1 answer:

5 0

It seems that you have missed to include the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. The group of protists that would be most likely to have cilia as adults and why is the heterotrophic protists would since they use them to gather food. Hope this helps.

How does the tympanic membrane work?

Ilya [14]

The eardrum (or tympanic membrane) works by taking in vibrations in the air, which causes the membrane itself to vibrate. These vibrations are transmitted through the three bones of the middle ear to the cochlea in the inner ear, which causes ripples in the fluids inside the cochlea which are registered as 'sounds'.
Hope that helped! =)

viktelen [127]

Answer:

A. 0

Explanation:

Both red-green color blindness and and shape of hairline are independently assorting genes.

Red-green color blindness is X-linked recessive while hairline shape is autosomal dominant.

The man who has widow's peak had a father with straight hairline. This means that the man is heterozygous for the trait.

Assuming hairline shape is represented by S. A heterozygous widow's peak man will have a genotype of Ss. A straight hairline woman will have a genotype of ss.

Assuming the allele for colour blindness is c. A normal vision man will have the genotype $X^CY$ while a color blind woman will have the genotype $X^cX^c$ .

$X^CY Ss$ x $X^cX^c ss$

The man does not have the color blind allele and a daughter will need two color blind alleles (one from the father and the other from the mother) in order to show the trait.

This means that the probability of the couple producing a color blind daughter is 0. Hence, the chance that any daughter the couple has will be color blind with a straight hairline is also 0.

The correct option is A.

What do cells need oxygen for

Answer:

Hello Queen Messy here!

Glycolysis in Respiration

Cells use oxygen to assist in cellular respiration. This type of respiration, called aerobic cellular respiration, converts stored energy into a usable form, chiefly by reacting glucose and oxygen through an intermediate. The first stage of aerobic cellular respiration, glycolysis, can be performed without oxygen. However, if oxygen is not present, cellular respiration cannot continue past this stage.

In glycolysis, glucose is converted to a carbon-based molecule called pyruvate. Two molecules of adenosinse tri-phosphate (ATP), a nucleotide that provides energy to cells, are generated during this process.
