Answer:

75%

Explanation:

If you drew a Punnett Square, you will see that the possible outcomes would be AA, Aa, aA, and aa. Three out of the four would exhibit the dominant trait.

Please help it’s biology!!!!!!

Answers

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

1÷4×100 = 25

Answers

Answer:

B.

Explanation:

In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.

There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.

Intraspecific competition is a competition between two living beings of the same species.

The monarch butterfly and the queen butterfly both belong to the same species- danaus.

Therefore, option B is correct.

To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices

Answers

Answer:

The missing answer choices are:

a. hypotonic

b. isotonic

c. osmosis

d. hypertonic

The correct option is d. hypertonic

Explanation:

A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.
