RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.
Option D
<h3><u>Explanation:</u></h3>
The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.
As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.
As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.
So the most possible cross that is given here is RrXtXt×RrXTY.
2+2=4. duh. IDK if this is a joke or what, but this is not high school.
answer
Its either a or d
cause i set the numbers to an equal denominator
Answer: Competition
Explanation:
An ecological niche is the place of a given organism within its ecosystem. A niche consist of limited resources such as food, shelter, space, light, desired temperatures, moisture for the organism to survive.
Two or more species of organisms may have similar basic needs and occupy the same niche. When different species population occupy the same niche, they compete for these limited natural resources.
Competition occurs when 2 or more organisms or populations in a community rely or need similar limiting resources.
Amino acids that must be obtained from foods in order for the body to function properly are called <u>essential amino acids.</u>
<u></u>
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Organic substances known as amino acids are primarily made up of nitrogen, carbon, hydrogen, and oxygen.
- Twenty distinct amino acids are required by your body for growth and optimal operation. Despite the fact that all 20 of these are crucial for your health, just nine are considered essential.
- These include <u>valine, tryptophan, isoleucine, leucine, lysine, methionine, phenylalanine, and threonine.</u>
- While your body may produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.
- Animal proteins including meat, eggs, and poultry are the richest providers of necessary amino acids.
- But some plant meals, such edamame and tofu made from soy, do contain all nine essential amino acids. They are "complete" sources of protein.
