Why do capillaries need to be thin walled?

Biology

That's because one of the functions of capillaries is to transfer things such as oxygen, carbon dioxide, waste, or similar things, between cells. A thin wall enables these transfers to go easier because diffusion of them is easier. If the walls were thick then the process would last longer.

A recessive X-linked gene mutation is known to generate premature baldness in males but is without effect in women. If a heteroz
Sergeu [11.5K]

Answer:

\frac{1}{4}

Explanation:

Let "XB " represents the dominant allele for no baldness

and let "Xb " represents the recessive premature male-pattern baldness

Genotype of affected male is Xb Y

Genotype of heterozygous female XB  Xb

Now when the above male and female are crossed, the following offspring are produced

Xb Y * XB  Xb

XB  Xb, XB Y, Xb Xb, Xb Y

Since, this Xb allele is only expressed in males, therefore females will not be affected by it

Hence, out of 4 offspring only one male offspring with "XbY" genotype will have premature baldness

Which types of renewable energy could / should we use more? Why?
bekas [8.4K]
We should use wind and solar energy more because those are the two main renewable energy sources, the sun shines a lot so we can use the power from that to power are houses, but at night that would be a problem, so at night you could use water as a renewable energy to power your house at night so you can get light, wind would be good if you live in a windy place like Cheyenne WY.

Approximately what percentage of the human genome actually codes for proteins?
34kurt

The correct answer is: 2.5%

The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.

• Telomeres-ends of DNA with protective role (prevents shortening of DNA),

• Non-coding RNA genes-e.g. genes for tRNA,

• Gene regulatory sequences such as promoter, enhancers and silencers.
