what organic molecules are in chicken
Answer:
Organic molecules present in chicken are Nucleic acid, proteins, carbohydrate and lipids .
Explanation:
Chicken itself has the all four organic molecules in it. Organic molecules are those having carbon in it. They are attached by covalent bonds, in which electrons are being shared within the atoms. The nucleic acids are DNA and RNA which helps in the making of the proteins which are found in the various structure and ought to perform various metabolic functions. Proteins are the building block of the amino acids. Lipids found are the fat bodies, burning of lipids gives us energy.
Chicken contains organic molecules such as proteins, lipids, carbohydrates, and nucleic acids, which are essential for various biological functions and nutritional needs. The nutritional value of chicken can vary depending on farming practices, which can alter the balance of these nutrients, like omega-3 fatty acids.
Explanation:The organic molecules found in chicken include a variety of biomolecules essential for life. Some of the primary categories of these organic molecules are proteins, lipids, carbohydrates, and nucleic acids. Proteins in chicken not only serve as a major source of dietary amino acids for building and repairing tissues but also play roles in various biological functions like enzyme and hormone activities.
Chickens are also a source of lipids, which include fats that are important for energy storage and hormonal functions. Carbohydrates present in chicken are generally found in small quantities and include glycogen, which is a stored form of glucose. Nucleic acids, like DNA and RNA, are present in every cell and are responsible for genetic information and protein synthesis.
Furthermore, chickens produce glycosylated proteins, adding the correct sugars to these proteins. Modern farming practices have influenced the nutritional composition of chicken, altering levels of essential nutrients like omega-3 fatty acid. It has been observed that intensively raised chickens now have higher fat content compared to their protein content, with reduced amounts of omega-3 fatty acids compared to chickens raised in the past.

What effort do enzymes have on the activation energy of exergonic and endergonic reactions
Activation Energy Of Exergonic Reactions:
A. increase
B. Decrease
C. Increase
D. Decrease
Activation Energy Of Endergonic Reactions:
A. Increase
B. Decrease
C. Decrease
D. Increase
Answer:
Enzymes 'reduces the activation energy' of both Exergonic and Endergonic Reaction by acting as a catalyst.
Explanation:
For example, in the case of 'carbonic anhydrase', enzymes act rapidly causing the chemicals to 'react 107 times faster' than they would normally. Enzymes are substrate specific meaning an enzyme working on one substance may not work on another. Function of the enzyme is identified by its 'shape of the protein' and arrangement of these molecules produces an area called activation site.Enzymes lower the activation energy of both exergonic and endergonic reactions.
Explanation:In biological systems, enzymes play a crucial role in lowering the activation energy of chemical reactions. Activation energy is the energy required to start a reaction. Enzymes facilitate reactions by providing an alternative pathway with a lower activation energy, allowing the reaction to occur more easily and at a faster rate. For exergonic reactions, which release energy, enzymes can help decrease the activation energy. For endergonic reactions, which require energy input, enzymes can still lower the activation energy required for the reaction to proceed.
Discuss the law of segregation and explain why each organism has two copies of gene for each trait expressed
Answer:
The explanation is provided in the explanation section
Explanation:
Gregor Mendel, who was referred to as the FATHER OF GENETICS discovered the principles that governs heredity in his several experiments. He observed that, for a particular trait, an organism receives two copies of a gene called ALLELE. This two copies are contributed by each parent in gametes during reproduction. An allele is a contrasting form of a gene, that is responsible for a particular trait of that gene.
For example, the height gene possesses two alleles T and t, which is responsible for a tall and short trait respectively. In an organism, two copies od this height gene will be present either same or different depending on which allele is contributed by each parent. This explains why a diploid organism possesses two alleles for a specific gene.
One of the principles of heredity discovered by Mendel is the LAW OF SEGREGATION, which states that the alleles of a gene will separate into gamete during gamete formation (meiosis). Mendel stated that only one form of a gene (allele) will be found in each gamete. For example, in an organism with Tt genotype, the gametes produced by this organism will either contain T or t allele.
The Law of Segregation states that genetic traits are split during gamete formation, producing offspring with two copies of each gene, one from each parent. This is due to the fact that most organisms are diploid, having two sets of chromosomes from both parents.
Explanation:The Law of Segregation, also known as Mendel's first law, states that during the formation of reproductive cells (eggs and sperm), pairs of genetic traits are separated or segregated from each other. This means each parent contributes one copy of the gene for each trait, resulting in the offspring having two copies of the gene - one from each parent. These copies then randomly assort into gametes, maintaining genetic variation.
As to why each organism has two copies of a gene, this is attributed to the fact that organisms are diploid. A diploid organism has two sets of chromosomes, one set from the mother and one from the father, and consequently, two copies of each gene. These genes often have slight variations, leading to diversity in traits like eye color, skin color, and so on.

snow. Which statement describes the particles
that make up the igloo?
(A) The particles in the snow have no kinetic
energy
(B) The particles in the snow are not attracted to
one another.
(C) The particles in the snow have some kinetic
energy, but the particles only move around in
place.
(D) The particles in the snow melt easily because
they have more kinetic energy than liquid
water.
The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.
Option C
Explanation:Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.
Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.

Final answer:
Asexual reproduction is most likely to result in a rapid growth in population.
Explanation:
The type of reproduction that is most likely to result in a rapid growth in population is asexual reproduction. Asexual reproduction involves the production of offspring without the need for a mate, and it can occur through various methods such as binary fission, budding, or fragmentation. Since asexual reproduction does not require the time and energy needed to find a mate, it can lead to a rapid increase in population size under favorable conditions. For example, bacteria can reproduce through binary fission, where a single cell divides into two identical cells. Each of these cells can then divide again, resulting in exponential population growth.

Which stage of cellula
respiration generates the most ATP molecules?
A.The Krebs cycle
B.Glycolysis
C.The electron transport chain
D.Fermentation
Answer:
The answer is C. The electron transport chain
Explanation:
Glycolysis involves the conversion of one glucose molecule into 2 molecules of pyruvate with the production of 2 ATPs and 2 molecules of NADH2. The molecules of NADH are used in the electron transport chain to produce more ATPs.The Kreb's cycle produces 2 ATP, 8 NADH and 2 FADH2.The electron transport chain converts 10 NADH and 2 FADH2 to produce 34 ATPs and 2 GTPs to yield another 2 ATPs.In total, one molecule of glucose yields 36 ATP molecules upon respiration.* Each NADH yields a total of 3 ATP molecules whereas each FADH2 yields 2 ATPs.

explain why controlling the proteins in an organism controls the organisms characteristics
Answer:
Controlling the proteins in an organism controls the organism's characteristics because proteins are enzymes, and enzymes catalyze and regulate chemical reactions, and therefore can control certain traits such as color, shape, or even gender.
Explanation:
Controlling the proteins in an organism regulates the organism's characteristics because translation regulates the protein expression of cells based on DNA sequences and eventually the characters are expressed.
What is the importance of protein expression?In general, the cell has genetic contents that are expressed in terms of transcription and translation, and here these are called the fundamental processes of the cell as they are required by the cells for enzyme formation, synthesis of the receptors, membrane protein, and expression of the traits. If the translation is regulated, then the message present in the DNA is also regulated, and the protein expression can be controlled.

In a certain species of plant, the color purple (P) is dominant to the color white (p).
According to the Punnett Square, what is the probability of an offspring being
white?
a. 0%
b. 25%
C. 50%
d. 75%
e. 100%
The probability of an offspring being white in the given scenario, assuming heterozygous parents, is 25%, as calculated using a Punnett square.
Explanation:The probability of an offspring being white in the given plant species, where purple (P) is dominant over white (p), can be determined by creating a Punnett square. If we assume both parents are heterozygous (Bb), the Punnett square would have one quarter (bb) representing white flowers. Therefore, there is a 25% chance that an offspring will have white flowers (rr). The other three quarters would result in purple flowers because of the dominant purple allele (P), showing a 3:1 ratio of purple to white.

Why is a dichotomous key called a dichotomous key?
Answer:
The name comes from the Greek “di” for “two” and “tome” for “cutting instrument.” As the name suggests, a dichotomous key arrives at the answer to species identification by presenting a series of questions with two possible answers.
Explanation:
You will understand better with the picture.
A dichotomous key is called so because it presents a series of two opposite choices (dichotomies) at each step to classify and identify organisms.
A dichotomous key is a systematic tool used by biologists and taxonomists to identify and classify organisms based on their observable characteristics. It is designed as a series of paired statements or questions, where each pair represents two opposite characteristics of the organisms being studied. The user must choose the statement that best matches the observed characteristics of the specimen they are trying to identify.
At each step of the key, the user makes a choice between the two options, leading them to the next set of characteristics that narrows down the possibilities. This process continues until the user reaches a specific name or classification for the organism.
The term "dichotomous" comes from the Greek word "dichotomia," which means division into two parts. The key's structure of presenting two opposing choices at each step helps to simplify the identification process and efficiently categorize organisms into specific groups based on their shared characteristics.
Dichotomous keys are widely used in various scientific fields, including biology, botany, zoology, and ecology, to identify and classify organisms in a structured and organized manner. They are valuable tools for researchers, students, and anyone involved in the study of living organisms.
