Mikayla is at the garden center picking out plants for her front garden. She sees flowers in many different colors and patterns.

Mr. Kim, the shop owner, sees Mikayla examining some camellias. He points out several kinds of flowers and explains how they end up with their color.
Choose the sentence from the passage that describes incomplete dominance.
1. These flowers are red and white because they have one red parent and one white parent.)
2. This is due to both alleles being expressed at the same time.)
3. But these pink flowers also have one red parent and one white parent.
4. Blending of colors occurs from mixing a dominant and recessive allele for an inherited trait.

What are the most likely percentages for offspring of two red/white-feathers parents?
weeeeeb [17]

Answer:

The question lacks options, the options are:

parents?

A.100% red/white-feather chickens.

B.50% white-feather chickens and 50% red/white-feather chickens.

C.33% white-feather chickens, 33% red-feather chickens, and 33% red/white-feather chickens.

D.25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens

The Correct answer is D

Explanation:

According to the question, the hybrid chicken has a mixture of red and white feather phenotypes expressed at the same time. This tells us that the red and white alleles are CODOMINANT in the chicken i.e. none is dominant or recessive over the other.

Let's assume that (R) allele is the red feather colour while (r) allele is for white feather colour. Therefore, the red/white feathered chicken will have a Rr genotype. In a cross between two red/white feathered chicken (Rr), the following offsprings will be produced RR, Rr, Rr and rr

RR- Homozygous red feather d chicken (1/4 × 100=25%)

Rr- Hybrid Red/White feathered chicken (2/4 × 100=50%)

rr- Homozygous white feathered chicken (1/4 × 100=25%)

Dinobryon is a species of protozoa that reproduces asexually. How is it better for the survival of the species for the protozoa
MakcuM [25]

Answer:

A. They do not use up any energy finding mates.

Explanation:

The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.

For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates

Therefore in the given case the correct option is A.

ankoles [38]

Answer:

The thyroid gland increase in size.

Explanation:

Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.  

In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.

During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the s
matrenka [14]

Answer and explanation:

Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.

These hormones have many functions and they all work together to prepare the individual for a fight or flight response -<em> like increasing heart rate and producing bronchodilatation</em>. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.

When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.
