Pea plants can have yellow seeds or green seeds. Which conclusion about the meaning of Y is correct if the allele combination Yy is for yellow seeds?

Answers

Answer:

yellow and dominant

Explanation:

In genetics, complete dominance occurs when a gene variant referred to as 'dominant allele' completely masks the expression of another allele referred to as 'recessive allele' in heterozygous individuals (i.e., individuals carrying one copy of the dominant allele and one copy of the recessive allele) at a specific locus. In this case, the yellow (Y) allele is dominant for the trait of 'color seed' with regard to the recessive (y) allele, which is responsible for the phenotype of green seeds, and therefore heterozygous individuals (Yy) will have yellow seeds.

The Doppler effect suggests that sound waves are relative to the observer. You know if an object is coming or going from the sound it makes. Light waves follow the Doppler effect also. However, instead of sound changing, you know if an object is coming or going _____.

Answers

from the brightness of the light of course. If the brightness is increasing it means the the light source is approaching and if the brightness is decreasing it means the light source is leaving.

Answer:

The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.

Explanation:

The doppler effect is a physical phenomenon. This phenomenon allows us to perceive if an object is approaching or moving away through the wave effect that that object produces in relation to an observer. This is because when a wave is propagated the speed of that wave depends on the environment in which it is being emitted. For this reason, the speed of this wave will be constant even if the observer moves, but the frequency and movement of this wave varies in relation to the observer's position. In this case, the Doppler effect suggests that the sound waves are relative to the observer. You know if an object is coming in or out of the sound it produces. The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.

Which of the following describes why wetlands are important to the water cycle?A.Dense vegetation helps filter out pollutants in the water.
B.Open meadows help to filtr out pollutants in the water.
C. Dense vegetation allows for biological magnification in the water.
D. Open meadows allow for biological magnification in the water.

Answers

C and D are not good answers: biological magnification is not something to be desired, as it makes pesticides and heavy metals more pronounced as they move up the food chain.

Among A and B A is the better answer: the vegetation is dense and this helps to filter out pollution.

Answer:

a

Explanation:

When an invasive species is introduced into a new habitat where it has no natural predators, it can quickly populate. Which best predicts the effect this will have on the native species of the habitat?A.
The native species will compete for resources in the habitat.


B.
The native species will thrive in the habitat.


C.
The native species will remove all of the resources in the habitat.


D.
The native species will destroy the habitat.

Answers

answer:

a. the native species will compete for resources in the habitat.

explanation:

since there are no predators for the introduced species to be monitored by, the native species will compete for resources that the introduced species is depleting.

What is the outcome of mitosis

Answers

Answer:

The correct answer is the formation of two daughter cells with same genetic material.

Explanation:

Mitosis is a type of cell division which produces two genetically similar daughter cells with the same genetic material.  

This type of cell division takes place in somatic cells where ploidy or number or chromosome number remains the same. It is also a way of the asexual mode of reproduction which produces clones with the same genetic material.

Thus, the formation of two daughter cells with the same genetic material is the correct answer.

 At the end of mitosis there is 4 daughter cells 

A dog called the Maltese doesn't shed. This type of dog most likely came about through _____. hybridization genetic engineering recombinant DNA cloning

Answers

Answer:

The correct answer would be hybridization.

Hybridization refers to the process by which organisms of different breed, species, or varieties are selectively interbred in order to produce offspring with desired characters.

Similarly, Maltese dogs were selectively bred in order to attain characters like the small size, less shedding of hairs et cetera.
