Brown eyes (b) are dominant over blue eyes (b) and straight tails (t) are dominant over curly tails (t) in opossums. a brown-eyed, straight-tailed opossum male was mated to a tester female. the offspring were: 3 brown eyes and straight tails 2 brown eyes and curly tails 4 blue eyes and straight tails 3 blue eyes and curly tails what was the genotype of the male?

Answers

Answer 1
When there is a tester mate it means that the genotype of that mate is known, most commonly that mate has all the recessive traits that are being studied so that we know that mate's genotype is homozygous recessive.
Therefore, in this case the tester female has probably blues eyes and curly tail, meaning that the only contributed combination of alleles from the tester mate is blue eyes and curly tail. As we can see by the results of the mating, the male would have to have all types of alleles. Because the male has a brown-eyed and straight-tailed phenotype it means that he has at least one allele that's for brown eyes and one that's for straight tail. Once the offspring includes all types of phenotypes, we can conclude that the male had also the recessive alleles for both characteristics.

Why does a lack of movement create swelling in barbara's legs?

Answers

A lack of movement creates swelling in Barbara's legs because the body relies on pressure created by the movement of muscles to circulate the blood which then moves it back up into the heart. Barbara's arms didn't swell because she is more likely to move them in a car than her legs.

One would expect to find this protein involved in the elongation of bacillus anthracis to form its typical shape

Answers

The protein involved in elongation of Bacillus Antrasis to form its typical shape is called FtsZ.
FtsZ is a GTpase that polymerises in nucleotide dependent manner head to tail to form a single stranded filaments that assemble into a contractible ring.
Final answer:

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function.

Explanation:

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function. For example, in the process of biological nitrogen fixation, the carrier protein leghemoglobin binds with a very high affinity to its substrate oxygen at a specific region of the protein where the shape and amino acid sequence are appropriate. If the shape or chemical environment of the active site is altered, the substrate may not be able to bind as strongly or not bind at all. Thus, for the protein to be fully active, it must have the appropriate shape for its function.

Study the diagram, which represents the general equation for photosynthesis. What do the letters Y and Z represent?

Y - glucose
Z - oxygen

Y - glucose
Z - carbon dioxide

Y - carbon dioxide
Z - hydrogen

Y - carbon dioxide 
Z - oxygen

Answers

Answer:

The correct answer is Y - glucose, Z - oxygen

Explanation:

In photosynthesis, plants- and also other organisms- take carbon dioxyde (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → glucose + oxygen

In the diagram, the equation is:

carbon dioxide + water + sunlight → glucose + oxygen

Answer:

The correct answer is A.

Explanation:

Y represents Glucose, a product of cellular respiration. Z represents Oxygen, which is also a product of cellular respiration.

(CO2 + Water + Sunlight = Glucose and Oxygen)

Most enzymes in living things are made up of
1. Carbohydrates
2. Lipids
3.Proteins
4. Nuclear acids
Someone please help me with this as soon as you can!

Answers

Most enzymes are proteins

Answer:

3. Proteins

Explanation:

Enzymes are naturally occurring groups of organic substances of protein origin (they can be form by 62 amino acid residues, such as 4-oxalocrotonate tautomerase enzyme monomer to 2500 residue size) with intra or extracellular activity that have catalyst functions. This is achieved by lowering the activation energy to allow a chemical reaction, resulting in an increased reaction speed and allowing the metabolism of living things. Importantly, although most enzymes are proteins, there are also enzymes consisting of RNA as ribozymes.

Answers

The answer to this question would be: B) is a living organism

Protist can reproduce by dividing its cells. The organism also can survive in water. In fact, water was vital for the most organism and water depletion can cause the cell to die. The protist doesn't mean it gets energy directly from sunlight. It was a producer that can produce energy from sunlight.

Answer:

B) is a living organism.

Explanation:

All living organisms must have 8 treats or characteristics to be called living things:

cellular organizationreproductionmetabolismhomeostasisheredityresponse to stimuligrowth and developmentadaptation through evolution

These eight characteristics are what make something a living thing, since the protist is made out of a cell, which has all of this characteristics, we can assume is a living organism, the other options could be truth, but we do not have enough information to say if they are or they aren´t true.

Anton thinks that glucose is a reactant of photosynthesis, but his classmate Jamila disagrees. Who is correct, and why?

Anton is correct because glucose is a substance that is present before the chemical reaction of photosynthesis takes place. 
Anton is correct because glucose is a substance that is formed from the chemical reaction of photosynthesis.
Jamila is correct because glucose is a product, not a reactant, of photosynthesis.
Jamila is correct because glucose is not involved in the chemical reaction of photosynthesis.

Answers

Answer: Jamila is correct because glucose is a product, not a reactant, of photosynthesis.

Photosynthesis is a chemical reaction that occurs in plants which produce their food in the form of glucose by trapping the light energy from sun and using reactants such as carbon dioxide from the atmosphere and water. This process occurs in the leaf cells of the plants.

On the basis of the above information, this can be concluded that Jamila is correct because glucose is a product, not a reactant, of photosynthesis.

Why are reduction division and haploid gametes important?

Answers

Answer:

This is in order to maintain the species number of chromosomes.

Explanation:

Reduction division occurs by meiosis and it is very necessary in organisms that reproduce sexually.

Meiosis will take place in the ovary and testis to produce haploid gametes that have half the number of chromosomes compared to the parent cell .

During fertilization the two gametes will fuse to form the offspring an offspring with the same number of chromosomes as the parent. The species number of chromosome has been maintained.

Without meiosis or reduction division the off-springs would have double the chromosomes as the previous generation did.

A nurse is evaluating the client's understanding of post cataract surgery instructions. the client needs further education when they state."i will report any yellow drainage to my provider"."i can return to my normal activities like cleaning my house and vacuuming.""i will report any nausea or vomiting"."my vision will improve over the next 4 to 6 weeks".

Answers

The answer to this question should be: "i can return to my normal activities like cleaning my house and vacuuming"

A post cataract surgery patient will be prone to an airborne allergen such as dust so it is not recommended to do any cleaning or be in a place with much dust. Vacuuming will increase the amount of the dust in the room and this might cause damage to the patient eye.

A nurse is evaluating the client's understanding of post cataract surgery instructions. The client needs further education when they state: I can return to my normal activities like cleaning my house and vacuuming.

Further Explanation:

The lens is that part of the eye which allows it to focus light or an image on the retina which is present at the back of the eye and is involved in converting light signal into nerve signal. Lens mainly consist of water and protein.

The cataract is the condition when there occurs clouding of the lens in the eyes which eventually affects the vision. This can affect either or both the eyes but cannot build out from one eye to another.

In normal vision, the proteins in the lens are present in a precise way which maintains the lens clear and allows the passage of light but with ageing, the protein may assemble together and start gathering to a small part of the lens which results in cataract.

Cataract surgery may increase the risk of retinal detachment.

There can be post-surgery effect of cataract treatment which may include itching, some fluid discharge, infection and mild discomfort.

Doctors may suggest the patients undergone cataract surgery to use some eye drops, wear an eye shield or eyeglasses and avoid bending from the waist and do the heavy household chores

The structure of hair is formed by keratin. Keratin is most likely which of the following polymers?

Answers

tbe answer is protein.

Answer:

Keratin is a protein.

Explanation:

Keratin is a fibrous protein that has the characteristics of rigid conformation, elasticity and impermeability to water. It has animal origin and is found in the vertebrate epidermis and in some epidermal appendages, such as hair, nails, hooves, feathers and scales. This protein is produced in cells called keratinocytes, which are the most abundant in the human epidermis.

Like any protein, keratin is made up of amino acids. It has a large amount of cysteine residues, which is responsible for 7% to 20% of the total amino acids present in keratin. Note that cysteine is mainly located in the terminal region of the keratin chains.

The atp synthase uses this gradient to restore adp back to atp. what is this process called?

Answers

The process is called OXIDATIVE PHOSPHORYLATION.
Oxidative phosphorylation is the process by which a free phosphate ion is added to ADP in order to produce ATP. This process take place in the mitochondrion and is a major source of energy for anaerobic organisms. The free phosphate ion is usually transferred from NADH or FADH2.
Final answer:

ATP synthase uses a proton gradient to restore ADP to ATP in a process known as chemiosmosis, which takes place during oxidative phosphorylation.

Explanation:

The process by which ATP synthase uses a proton gradient to restore ADP back to ATP is called chemiosmosis. This occurs during oxidative phosphorylation, a key part of cellular respiration where the energy stored in the electrochemical gradient, developed due to the movement of protons (H+), is utilized. As protons flow through ATP synthase, much like water flowing through a turbine, they provide the energy needed for the enzyme to catalyze the production of ATP from ADP and inorganic phosphate (Pi).

Given a template strand of 3'-atgcttggaca-5' and a partially-made complementary strand containing only 5'-tac-3', what would be the sequence of the new strand of dna (including the 5'-tac-3') if the only additional nucleotides available to dna polymerase were those containing the bases g, a, and c?

Answers

A complementary strand is complementary to the template strand when in the opposite direction, in this case 5'-3', the nucleotides that it contains are complementary to those of the template strand. Thus, the partially-made complementary strand 5'-TAC-3' will bind to the template strand starting on the 3'-ATG-5' portion. Then it is elongated by the DNA polymerase only up to the next nucleotide A, not included, because its complementary nucleotide is T which is not available. So, the sequence of the new strand on DNA would be 5'-TACGAACC-3'.

compare the productivity of terrestrial and aquatic ecosystems against the percent of Earth’s surface area they occupy.

Answers

The 6 terrestrial ecosystems are tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, and desert, these are distinguished from aquatic ecosystem by the limited supply of water. The two types of aquatic ecosystems are marine and freshwater.

Terrestrial productivity is more effective in the wet tropical climates as the net primary productivity decreases between equatorial and polar regions due to less sunlight and therefore there is a temperature decrease. Global productivity is limited by factors of water and sun, as most ecosystems rely on photosynthesis and water. Marine productivity tends to be higher, as rivers and water carry more nutrients and deposit them in other ecosystems. The most productive regions are areas such as wetlands and estuaries. i hope this helps!

1. Step 1 The Sun emits energy. 
2. Step 2 Plants absorb energy from the Sun and use it for photosynthesis. 
3. Step 3 A rabbit eats the plants and uses the energy for growth and respiration. 
4. Step 4 A fox eats the rabbit and uses the energy for growth and respiration. 
5. Step 5 The fox dies and is decomposed. 

In an ecosystem, the energy flows from the producer to consumer levels. The plants utilise the energy from the sun and convert it into chemical energy. The chemical energy is stored as a form of energy molecules in the plants. The primary consumers eat the plants and get the chemical energy. The tertiary consumers eat the primary consumers and obtain energy from them. The dead organism is decomposed and the organic nutrients are restored in the soil.

Hence, the correct sequence would be:

1. The Sun emits energy. 

2. Plants absorb energy from the Sun and use it for photosynthesis. 

3. A rabbit eats the plants and uses the energy for growth and respiration. 

4. A fox eats the rabbit and uses the energy for growth and respiration. 

5. The fox dies and is decomposed.
