In a plant, a single locus affects both berry color and berry size. There are two mutant alleles (R1 and R2) in addition to the wild-type allele (R0). Individuals that are R0R0 have large, white berries. Individuals that are R1R1 or R0R1 have red berries, individuals that are R2R2 or R0R2 have small berries, and R1R2 individuals have berries that are both red and small. Thus...R1 is dominant to R2.R2 is dominant to R1.R1 and R2 exhibit incomplete dominance.R1 and R2 exhibit codominance.R1 and R2 exhibit pleiotropy.

Given 4c + 5 = 0 and c Is a real number what is the multiplicative inverse of 4c + 5?

Answers

The word multiplicative inverse means that the reciprocal of a number. Then the multiplicative inverse of the letter x which is given is, one divided by x.
1/x.
Therefore, the multiplicative inverse will be 1/x (4c + 5 ).

Multiplicative inverse means the reciprocal of a number. Therefore, the multiplicative of x is equal to 1/x. For the expression given above, the multiplicative inverse should be 1/(4c+5). Hope this answers the question. Have a nice day.

What is the body system that controls growth and metabolism, and regulates reproduction, through hormones?

Answers

I think it is endocrine glands

Final answer:

The endocrine system regulates growth, metabolism, and reproduction through the production, secretion, and regulation of hormones, which act as cellular and organ 'messengers'. Key components include the hypothalamus and pituitary gland, and diseases often affect these components.

Explanation:

The body system that controls growth, metabolism, and reproduction through the use of hormones is the endocrine system. This system controls body processes through the production, secretion, and regulation of hormones, acting as chemical messengers that function in cellular and organ activity. It plays vital roles in growth, metabolism, and sexual development. For regulation, it uses hormones like the growth hormone (GH), which promotes protein synthesis and tissue building and the regulation of reproductive system by hormones from the pituitary gland, and the adrenal cortex.

Common human endocrine system diseases include thyroid disease and diabetes mellitus. The hypothalamus plays a crucial role in controlling the endocrine system, sending signals to the pituitary gland, releasing different hormones affecting other glands and cells, and thereby regulating various bodily functions.
