Answer:
C. Aa x Aa
Explanation:
According to this question, one gene coding for fur coloration in mice is involved. The allele for agouti coloration (A) is a dominant trait over black fur (a). This means that a heterozygote mouse will have an agouti coloration.
Based on this question, two parents were crossed to produce offsprings that have a ratio of three agouti individuals (3) to one black individual (1). Based on this phenotypic ratio, only parents that are both heterozygous for the fur color gene can produce it. That is, a cross between Aa and Aa mice parent. Hence, the genotype combination of Aa × Aa is possible for the parent to produce offsprings with 3 Agouti : 1 black.
Answer: C) Aa x Aa

Apples, peas, orange, banana, carrot, lettuce, turnip, pear, grape, potato
Answer: The caterogries are fruit and vegtables
Explanation: The fruits are: apple, orange, banana, pear, and grape. The vegtables are: peas, carrot, lettuce, turnip, and potato
We classify the given fruits and vegetables on the basis of true seeds and bogus seeds.
True seeds: Apple, Peas, Orange, Lettuce, and Pear.Bogus seeds: Banana, Carrot, turnip, grapes, and Potato. What do you mean by Seeds?Seeds may be defined as a reproductive unit of flowering plants which are capable of inducing other identical plants.
Banana, potato, grapes, orange, apple, etc. have fleshy endocarp that surrounds either the true seeds or bogus seeds.
Sometimes, bogus seeds are not visible with our bare eyes.

Answer:
I belive that the answer is B
Explanation:
I believe that it's B because if the rabit population continued to grow then it will allow the soil to become more fuirtle because of the dropings that the rabbits leave behind. This would cause more plants and growth in the habitat, which would lead to economic growth

Answer: Your answer is Sexual reproduction
Explanation:
The sperm and eggs produced with sexual reproduction provide genetic diversity because their gene combinations differ from those in the parent organisms. Asexual reproduction is called asexual reproduction because the person splits into two people that have the same genes, as opposed to sexual reproduction.
If you’re good in biology/science, plzzz help!
Answer:
D is the correct answer
Explanation:
During replication, you must find the complementary DNA strand that matches.
In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine (A) always pairs with (T) thymine, and (G) guanine always pairs with (C)cytosine.

when does a star start to die
Answer:
Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up.
study the punnett square below. what percentage of the offspring are heterozygous
Answer:
50%
Explanation:
Heterozygous is when both of the alleles are different. Since AA and aa are the same allele, the other two Aa and Aa have on capital and one lowercse and for that reason they are different and thus heterozygous. Since 2.4 are heterozygous, 50% is the answer.

- Cyanide is a strong cytochrome c oxidase inhibitor. Cytochrome c is the last enzyme in the
electron transport chain. If cell is exposed to cyanide, most of the cyanide will be found in which
of the organelles?
Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.

What happens in the light reaction of photosynthesis?
What happens in the dark reaction of photosynthesis?
What five factors affect photosynthesis and its rate? How?
Answer:
Ans - 1 Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
Ans-2 The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
Ans-3 The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
