Food provides the raw materials for biosynthesis and energy for cell activities. The body needs food, for growth and development and also for energy; these foods include; proteins, carbohydrates, fat, vitamins and minerals. Food helps us to stay healthy and productive; through various functions; for example proteins; are needed to build, maintain and repair muscle, blood, skin and bones and other tissues and organs in the body.
Answer:
Explanation:
A: Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton's Second Law of Motion
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.
You observe a species of bird that, upon hatching, has contact with its parents only while being fed. You also never hear the parents sing during the feeding process. What would you propose about song production in this species of bird?
A. Song learning in this species is most likely learned behavior.
B. The period of imprinting is likely later in the bird's life.
C. This species does not hear.
<span>D. Song production in this species is most likely innate behavior.
the answer is d im pretty sure
