Which describes the mating is organisms that have different homozygous alleles for a single trait? A: monohybrid cross
b: dihybird cross
c: homozygous cross
d: heterozygous cross

Answers

Answer 1

Answer: The answer is A

Breeding of individuals that have genes for a single trait:
MONOHYBRID CROSS.

We call it a monodihybrid cross when we are considering a cross with only one trait or characteristic.
"mono" means one and "hybrid" means that each trait will have two different alleles (for gene A: A or a), one is dominant and the other is recessive.

Answer 2

Answer: A: monohybrid cross describes the mating is organisms that have different homozygous alleles for a single trait.

Imagine that you are studying the control of β-globin gene expression in immature red blood cells (mature red blood cells contain β-globin protein but lack a nucleus and therefore the β-globin gene). If you deleted a sequence of DNA outside the protein-coding region of the β-globin gene and found that this increased the rate of transcription, the deleted sequence likely functions as a(n) _____. a. enhancer b. promoter-proximal c. element promoter d. silencer e. any of the above

Answers

Answer:

d. silencer

Explanation:

Based on the information provided within the question it can be said that the deleted sequence most likely functions as a silencer. This term refers to a DNA sequence that is located thousands of base pairs away from the gene that they actually control. In this situation, seeing as the DNA sequence that was found outside the protein coding region actually affected the rate of transcription when it was deleted then it is considered a silencer.

Answers

i think science is an interesting and essential subject, mainly i like the fact that having knowlege of biology,etc can help patients and sick people. Its obvious science is an important subject. But science cant explain everything, like about religion for instance scientists say the universe is created from big bang but religious people say god made it , so yeah. I mostly love science because of how amazing doctors are, helping people and all.

Which of the following could be a hypothesis for what causes a scarlet ibis to have red feathers?A. the red feathers make the bird more beautiful to people
B. A chemical in the birds food produces the red coloring
C. What does the scarlet ibis eat?
D. The feathers are red because a wizard cursed the bid long ago

Answers

The answer is C because it seems like the most logical answer

Final answer:

The hypothesis for what causes a scarlet ibis to have red feathers is that a chemical in the bird's food produces the red coloring.

Explanation:

B. A chemical in the bird's food produces the red coloring. In this case, the hypothesis suggests that the red feathers of the scarlet ibis are caused by a specific chemical component present in the bird's food. This hypothesis can be tested by conducting experiments to analyze the bird's diet and investigating the effects of different foods on the coloration of the feathers.
