stellarik [79]

Complete question:

___BLANK___ system contains glands that secrete hormones into the bloodstream, whereas the ___BLANCK__system secretes substances through ducts.

Answer:

The ENDOCRINE system contains glands that secrete hormones into the bloodstream, whereas the EXOCRINE system secretes substances through ducts.

Explanation:

Those tissues that produce hormones might be classified as:

  1. endocrine glands (produce hormones exclusively),
  2. exocrine glands (produce hormones and other secretions),
  3. non-glandular tissues that secrete hormones but are not glands.
  • Endocrine organs, also known as ductless glands or endocrine glands, release their secretion directly to the bloodstream. Blood transport hormones to target cells, tissues, and organs, where they stimulate a change in metabolic activities
  • Exocrine glands release their secretions to a duct of different tissues where they act, such as the internal or external surface of cutaneous tissues, stomach mucose, or pancreatic ducts.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) f
lord [1]

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White
