Section 39.2 discussed the mechanism by which threonyl-tRNA synthetase attaches threonine to the proper tRNA while preventing th

e attachment of the similar amino acids valine and serine. Using this as a model, explain how an isoleucyl-tRNA synthetase might prevent the incorrect addition of the similar amino acids leucine and valine to its target tRNA.
Valine could fit in the activation site.
[ Choose ] FALSE TRUE
Isoleucine could fit in the activation site.
[ Choose ] FALSE TRUE
Leucine could fit in the activation site.
[ Choose ] FALSE TRUE
Valine could fit in the editing site.
[ Choose ] FALSE TRUE
Isoleucine could fit in the editing site.
[ Choose ] FALSE TRUE

ioda

Answer:

The correct option is <em>lower.</em>

Explanation:

Schizophrenia can be described as an inherited disease and it is a type of mental illness. As Armend has an identical twin brother with diagnosis of schizophrenia hence, he will have more chances than Robert whose fraternal twin sister has schizophrenia.

As fraternal twins develop from two different eggs hence, the chances in them having the same disease will be lower. Identical twins develop from the same egg, hence they will have more chances of having the same inherited disease.

Give one example of how the testing of Platismatia glauca could benefit future ecological research of this forest.
storchak [24]

Answer:

Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

hope this helps:)

why does the presence of 22 large herbivore species at Mpala seem to contradict the competitive exclusion principle Dr. Pringle
stealth61 [152]

Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.

On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.

The ovarian cycle describes the monthly events of a post-pubescent ovary that causes a small number of primary follicles to grow
Damm [24]

Answer:

The ovarian cycle regulates endocrine tissue preparation, and egg release in female body.  

The first half of the ovarian cycle as the follicular process. Slowly growing rates of FSH and LH are causing follicle development on the ovary surface. This cycle makes the egg primed for ovulation. As the follicles develop they start releasing estrogens and low progesterone levels. Progesterone locks the endometrium in order to help ensure pregnancy. It takes about seven days to travel ovum through the Fallopian tube and to get implanted in uterus. There are 30-60 cells at this point of evolution, called the morula. If there is no pregnancy implantation the lining would be sloughed off. estrogen levels increase after around 5 days, and the menstrual cycle enters the proliferative process. The endometrium starts to regrow, replacing the weakening blood vessels and glands at the end of the last cycle.
