A. Sex cell
It looks like there’s more to the problem but since you only gave one I can only answer one. Hope this helps
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
<u>Genotypic</u>
BB : Bb : bb
1 : 2 : 1
<u>Phenotypic</u>
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
The correct answer is C. I hope this helps.
Answer:
The four-letter word which speaks to the ability of an organism to modify its behavior or actions to external stimuli is <u>Move.</u>
Explanation:
Movement gives organisms the ability to move away from or towards an external stimulus depending on whether it is a detrimental stimulus or a favourable one.
Examples of stimuli are:
- Light: All organisms respond to the presence of light. Some stay away from it and remain at sleep until the sun goes down. They are called nocturnal. Others gravitate towards it. Plants always grow towards light.
- Temperature: Some organisms favour cold environments, other the temperate parts of the earth
- Sound: The sound of a carnivorous animal such as the lion will put a deer to flight. The sound of a mother hen calling out to her chicks will attract them to her.
