Answer:
Bacteria can change and mutate with time and can become virulent from avirulent species.
Explanation:
If a bacteria is considered harmless or avirulent, then the bacteria will not necessarily affect the animal species.
But when the species come into contact with other sick species caused by the microbe will make the bacteria virulent. This shows that bacteria can change with time, depending on the environment it is living in.
A microorganism can mutate or change with time and can become virulent.
Thus we can draw this conclusion, bacteria can change and mutate with time and can become virulent from avirulent species.

Which action could lead to foodborne illness from cross-contamination?
a) thawing meat at room temperature
b) failing to quickly refrigerate cut up fruit
c) eating chicken that is not fully cooked
d) chopping meat and vegetables on the same cutting board
Answer:
The correct answer is d) chopping meat and vegetables on the same cutting board.
Explanation:
There should be two different cutting boards for chopping meat and vegetable separately to prevent cross-contamination. Raw meat may have lots of pathogenic bacteria like Salmonella, Shigella, E.coli, Listeria, etc which can contaminate the board and the vegetable which is cut on the same board.
So if you consume the contaminated food then you can get foodborne illnesses. Therefore separate board should be used for cutting veg and non-veg items and the board should be washed with soapy water after each use to wash the remaining bacteria from board. So the right answer is d.
Answer:
d
Explanation:
Which of the following foods is likely to keep a person satiated for the longest period of time?
a. a bean and cheese burrito
b. a serving of full-fat ice cream
c. a bowl of rice cereal in whole milk
d. a tossed salad with oil and vinegar dressing
Answer:
The correct answer is option a. "a bean and cheese burrito".
Explanation:
A bean and cheese burrito is a food that keeps a person satiated for a long period of time. Beans are legumes that are high in protein and fiber, two components that help people to have a feeling of satiation. Also, cheese contributes to the feeling of satiation, because in average it has 7 grams of protein per ounce and 5 to 10 grams of fat per ounce.

In general, what is the primary ecological role of prokaryotes?
A. breaking down organic matter
B. serving as primary producers in terrestrial environments
C. adding methane to the atmosphere
D. parasitizing eukaryotes, thus causing diseases
E. metabolizing materials in extreme environments
Answer:
The correct answer is A. breaking down organic matter
Explanation:
Bacteria and archaea are the domains that come under prokaryotes. These organisms lack nucleus. They play an important role in the nutrient cycle. Most of these organisms are heterotrophs and consume organic matter to gain energy.
They play an important role in breaking down the organic matter and releasing the nutrient from them in the environment so they helps in circulating the nutrients in the ecosystem.
For example, different methanogens and acid-forming bacteria decompose organic waste of industry and agriculture and produce manure and biogas during anaerobic decomposition. So the correct answer is A.
The primary ecological role of prokaryotes is to break down organic matter, which is crucial in the carbon and nitrogen cycles for maintaining balance within ecosystems.
Primary Ecological Role of Prokaryotes
The primary ecological role of prokaryotes is breaking down organic matter. Prokaryotes are essential in nutrient cycling, particularly in the carbon and nitrogen cycles. They decompose dead organisms, returning vital nutrients to the environment, and fix nitrogen to make it accessible to plants. Additionally, some prokaryotes are involved in bioremediation, where they clean up pollutants from the environment. Prokaryotes also contribute to the production of oxygen and some even inhabit human bodies, providing health benefits and aiding digestion. In ecosystems, they play various roles that are critical to maintaining the balance and supporting life.
_____ was the first taxonomist to group animals by blood color and plants by size and shape. 1. aristotle 2. linneaus 3. adam 4. cordus
Answer:
Answer is Aristotle.
Explanation:
Aristotle was a pioneer in the field of philosophy and science. This is because of his contributions to these fields.
He was considered as the first person to developed the classification system, where he grouped organisms into two, namely plants and animals. He also created subgroups for these two major groups.
Plant subgroup are small, medium and large.
Animal subgroup are Water, land , Air.
The classification system of Aristotle was considered as not very good because of some reasons. For example, he grouped everything that can fly together, that is, flying insects and some birds that can fly were grouped together, while birds that couldn't fly were left out of the group.
A popular lab that can be performed by students is to test the reaction rate of catalase enzyme when it acts on the substrate hydrogen peroxide. Catalase has the ability to break down hydrogen peroxide. Catalase can be found in beef liver from the grocery store! However, if the beef liver is boiled first, the catalase will not be able to break down hydrogen peroxide. What is the variable affecting enzyme function
The variable affecting the enzyme action is temperature.
Explanation:Catalase is the enzyme which acts upon the "substrate hydrogen peroxide", breaking down them into water and oxygen gas. Each and every enzyme is a protein, which has a tertiary structure which is essential for the enzyme action. The tertiary structure of the enzyme provides the site of enzymatic action where the substrate do gets attached for the enzymatic action to take place.
Temperature, or heat, changes the protein structures irreversibly after a certain range. So if the beef liver is boiled, then the enzyme structure gets permanently changed, which is why the catalase cannot breakdown the peroxides, after boiling.
In the given experiment, the variable affecting enzyme function is temperature. The high temperatures achieved through boiling lead to the denaturation of the catalase enzyme in the beef liver, thus inhibiting its ability to breakdown hydrogen peroxide.
Explanation:In this experiment, the variable affecting enzyme function is the temperature. By boiling the beef liver, which contains the enzyme catalase, the heat alters the enzyme's shape or denatures it, thereby inhibiting its ability to function and interact effectively with its substrate - hydrogen peroxide. Enzymes like catalase are proteins, and their functionality is deeply tied to their structure. When the structure is altered due to high temperatures as in this case, the enzyme loses its ability to catalyze the reaction - hence, no breakdown of hydrogen peroxide.
The factor affecting the enzyme's activity here - temperature - is what is referred to as an environmental condition that impacts enzymatic function, alongside others such as pH and substrate concentration.

The oxygen that is released as o2 during photosynthesis came from _____________ molecules.
Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
The oxygen (O2) released during photosynthesis comes from water molecules. This happens during the light-dependent reactions of photosynthesis where water molecules are split and oxygen is released as a by-product.
Explanation:
The oxygen that is released as O2 during photosynthesis comes from water molecules. The process of photosynthesis occurs in plants, algae, and some bacteria where light energy typically from the sun is used to convert carbon dioxide and water into glucose (a sugar) and oxygen. In detail, during the light-dependent reactions of photosynthesis, water molecules are split, thereby releasing oxygen as a by-product. This oxygen is what we, and other animals, breathe.

Increased force output of the synergists for hip extension to compensate for the weakened gluteus maximus is an example of which of the following?
a. Wolff's law
b. Synergistic dominance
c. Autogenic inhibition
d. Davis's law
Answer:
b. Synergistic dominance
Explanation:
The stabilizing muscles will always be synergistic, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.
In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.

Using the principle of independent assortment, complete the Punnett square to show the results of an F1 cross between two individuals heterozygous for both pod color (C = green and c = yellow) and pod shape (S = smooth and s + constricted). The gametes and some of the genotypes of the F2 offspring are given.
Answer:
9:3:3:1 ( 9 dominant pod color and shape, 3 heterozygous pod color and homozygous recessive pod shape, 3 homozygous recessive pod color and heterozygous pod shape and 1 recessive homozygous pod color and pod shape)
Explanation:
Mendel's law of independent assortment posits that the alleles of two (or more) different genes get assorted into gametes independently of one another. This implies that the allele a gamete receives for one gene does not influence the allele received for another gene.
In the question given;
We will take a critical look at the cross between two pure-breeding pod color and pod shape:
Pod color (green) = C
Pod color (yellow) = c
Pod Shape (smooth) = S
Pod shape (constricted) = s
The F1 progency of the cross between the heterozygous pod color and pod shape will be:
Cc × Ss
= CS, Cs, cS, cs
From the question, we are to complete the punnett square of the results of the F1 generation, i.e if the F1 progeny assorts independently, what will be the results (F2 generation)
i.e : CS, Cs, cS, cs × CS, Cs, cS, cs
The Punnet Square is in the attached file below.
The results of this dihybrid cross are as follows:
CCSS, CCSs, CCSS, CcSs, CCSs, CcSs, CcSS, CcSs, CcSs (all dominant pod color and shape) "9"
CCss, Ccss, Ccss (heterozygous pod color and homozygous recessive pod shape) "3"
ccSS, ccSs, ccSs (homozygous recessive pod color and heterozygous pod shape)
ccss (recessive homozygous pod color and pod shape)
We can therefore conclude that the results of the Punnet Square of the F1 generation is in the ratio of 9:3:3:1
Which of the following is the term for an abnormally low white blood cell count?
Answer:
The correct answer is- Leukopenia
Explanation:
White blood cells are present in our blood which protect our body from foreign antigens like bacteria, viruses, etc. When these white blood cells decrease abnormally in number then this condition is called leukopenia.
White blood cells contain different cell which protect our body from different type of infections. So there are different types of leukopenia according to the particular white blood cell whose number became low.
For example when neutrophils number in the body decrease it is called neutropenia. So the correct answer is leukopenia.
Leukopenia is the term for an abnormally low white blood cell count which increases individual's risk for disease due to immune system weakness.
Explanation:The term for an abnormally low white blood cell count is Leukopenia. This condition occurs when too few leukocytes (white blood cells) are in the blood. A low white blood cell count leaves the individual at a higher risk for disease since these cells play a significant role in the immune system. Their production begins in the bone marrow, and abnormalities with this can cause deficient counts. Matters are further complicated when abnormally low lymphocyte counts occur, as a result of chronic illness or immunosuppression.

All your cells contain proto-oncogenes, which can change into cancer-causing genes. Why do cells possess such potential time bombs?
The given question is incomplete. The complete question is:
Question: All your cells contain proto-oncogenes, which can change into cancer-causing genes. Why do cells possess such potential time bombs?
A. Cells produce proto-oncogenes as a by-product of mitosis.
B. Proto-oncogenes are necessary for the normal control of cell growth and division.
C. Proto-oncogenes protect cells from infection by cancer-causing viruses.
D. Proto-oncogenes are unavoidable environmental carcinogens.
E. Proto-oncogenes are genetic junk that has not yet been eliminated by natural selection.
Answer:
B. Proto-oncogenes are necessary for the normal control of cell growth and division.
Explanation:
The process of cell division is under tight regulation by a family of extracellular growth factors, specific proteins that trigger cell division and the tumor suppressor genes that normally inhibit cell division. Defects in these genes can lead to cancer.
For example, the protein encoded by tumor suppressor gene p53 stimulates the synthesis of p21 which in turn inhibits the cyclin-cdk2 to block entry of G1 cells into the S phase until the DNA is repaired. Mutations in tumor suppressor genes retinoblastoma and p53 allow cells to proceed to the S phase irrespective of DNA repair.
Likewise, a mutation in ras proto-oncogene encodes a protein with no GTPase activity. The mutant Ras protein is always in its activated form, regardless of the signals from normal receptors. This makes the cells to divide in an uncontrolled manner.
Proto-oncogenes are genes essential for normal cell function, however, when mutated, they may cause uncontrolled cell division leading to cancer. Other factors, such as underactive tumor suppressor genes and epigenetic changes, can also contribute to cancer development. Active research is underway to utilize the reversibility of these changes for cancer treatment.
Explanation:Every cell in our body contains proto-oncogenes, which are essential for normal cell function and growth. However, these can mutate into oncogenes, setting off the equivalent of biological 'bombs' by causing uncontrolled cell proliferation, leading to cancers such as Burkett's Lymphoma. Proto-oncogenes and tumor suppressor genes work in tandem, like the accelerator and brakes of a car, to control cell cycle. Unwanted cell division and proliferation can occur due to three main scenarios: proto-oncogenes becoming overactive, tumor suppressor genes becoming underactive, or through epigenetic alterations.
Epigenetic changes such as methylation and deacetylation can silence genes, and these changes are common in cancer. Because these changes are temporary and reversible, designing drugs and therapies that can reverse these changes is an area of active research in cancer treatment.
Other proteins that influence the cell cycle, in addition to cyclins and cell-surface receptors for growth factors, have potential oncogenetic properties. An example is the Cdk gene, which when altered, can speed up cell cycle progression.
