How are muscle cells in bone cells similar

Biology
1 answer:
arlik [135]3 years ago
7 0

Explanation:

Bones shape our body and help is to stand up straight. Muscles are attached to bones, they help us walk and run and smile. All the bones in our body make up our skeleton - from the top of our skill to the tips of our phalanges at the end of our toes. Muscles stretch across our bones and are attached with tendons.

9. why do mammalian muscle cells perform lactic acid fermentation (instead of, say, ethanol fermentation)?
Crank

Alcoholic fermentation and indeed most forms of fermentation are low-energy producing. The waste products are often medium-sized hydrocarbons/alcohols that, when fully oxidized to carbon dioxide provide more energy.

Cells ferment sugars to lactic acid B. During training. This is why your muscles are sore and sore during exercise. Essentially, building this lactic acid causes your muscles to scream for oxygen and use a simplified fermentation process to meet their energy needs, which is not efficient at all.

Yes, animals will ferment for a short time if they are not supplied with enough oxygen. Humans perform lactic acid fermentation when the body urgently needs a lot of energy. If you sprint as fast as you can, your cells only have a few seconds of ATP stored. When stored ATP is depleted, muscles begin to produce ATP through lactic acid fermentation.

Suppose the human trait for freckles is controlled by a simple dominant and recessive relationship at one locus. Freckles, F, is
Dennis_Churaev [7]

Answer:

0.549 is the frequency of the F allele.

0.495 is the frequency of the Ff genotype.

Explanation:

<em>FF </em>or <em>Ff</em> genotypes determine freckles, <em>ff</em> determines lack of freckels.

In this class of 123 students, 98 have freckles (and 123-98= 25 do not).

If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:

q²= 25/123

q²=0.203

q= \sqrt{0.2

q= 0.451

<em>q </em>is the frequency of the recessive f allele.

Given <em>p</em> the frequency of the dominant F allele, we know that:

p+q=1, therefore p=1-q

p=0.549 is the frequency of the F allele.

The frequency of the Ff genotype is 2pq. Therefore:

2pq=2×0.549×0.451

2pq=0.495 is the frequency of the Ff genotype.
