The stage that scientists begin to ask questions and attempt to explain observations is A. forming hypotheses. This is because a hypothesis is basically a testable question about observations scientists make.
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
Only males can be carriers for X-linked recessive traits, False, it should read "Only females can be carriers for X-linked recessive traits."
<h3>What is an allele in a gene?</h3>
An allele is defined as an allele is a variant form of a gene.
For example, if both of your parents have green eyes, you might inherit the characteristic of green eyes from them.
Or if your motherhas freckles, you might have freckles too because you inherited the characteristic for freckles
Thus, option "A" is correct.

Answer:
He need to eat 275 g
Explanation:
2000 = 100
5500 = 2000÷100= 20 = 5500÷20 = 275
He need to eat 275 g
