7. An extremely rare X-linked recessive genetic disorder known as Norrie disease affects the eyes
and can lead to blindness and in some cases hearing loss. There are only 400 known cases of
Norrie disease worldwide. Explain why it is virtually impossible for a baby girl to be born with
Norrie disease.

Answers

Answer: Girls need to inherit two affected chromosomes to develop the disease, and it may also happen that the affected chromosome is inactivated in the eye (if it has only one)

Explanation:

Norrie's disease is an inherited eye disorder affecting males, which is characterized by abnormal or immature development of the retina (light-sensitive nerve tissue lining the back of the eye) and possible deterioration of the iris (colored part of the eye) and eyeballs. X-linked recessive inheritance is one of the ways in which a genetic trait or condition is passed from parent to child when there are mutations in a gene on the X chromosome from either the father or the mother. Females possess two X chromosomes, while males possess one X and one Y chromosome. In males, the presence of a mutation on the X chromosome causes the disease, since it is the only X they possess. In females, both X chromosomes need to be affected if it is a recessive condition.

So, the disease is inherited in an X-linked recessive manner, which means that almost all affected individuals are male. However, the sons of affected males will not have the mutation since they only inherit the Y chromosome, while all their daughters will be genetic carriers of the mutation because they inherit the affected X chromosome, although without clinical symptoms but being carriers. On the other hand, the mother will pass one of her two X chromosomes (which may or may not be affected) randomly to both her male and female offspring (if they are male, they will be affected and if they are female they will be carriers unless they also inherit an X chromosome from their father). So the only way for females to develop the disease is for their two copies of the gene to be mutated if both parents have the mutation.

But female carriers could be affected by inactivation of their X chromosome with the correct sequence. X chromosome inactivation is a random process that happens separately in individual cells during embryonic development. That is, one cell may inactivate the paternal X chromosome, while others may inactivate the maternal X chromosome. This is because a dosage compensation is necessary, since the Y chromosome in males is not homologous to the X, it does not have the same genes, so if females would express both X chromosomes, they would have twice as many genes as a male.  All the descendant cells of each of these original cells will maintain the same pattern of X chromosome inactivation.

In females, one X chromosome is inactivated in each tissue in an arbitrary manner. Then, in addition to having to inherit two affected chromosomes, it may also happen that the affected chromosome is inactivated in the eye (if it has only one).

answer:

it occurs in two stages: transcription and translation

explanation:

transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. it includes three steps: initiation, elongation, and termination. after the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.translation occurs at the ribosome, which consists of rRNA and proteins. in translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. then, rRNA helps bonds form between the amino acids, producing a polypeptide chain.

Explanation:

How would you expect the number of births to compare to the number of deaths in a population that was changing?

Answers

Population Growth - Basic Information
All populations change in size with time
- if births exceed deaths, the population grows
- if deaths exceed births, the population shrinks
- only when births equal deaths does the population stay the same
Other Population Growth Factors
Populations can also change size if organisms move in (immigration) or leave (emigration)

Putting It All Together
We can write a simple equation to show population growth as:

Change in Population Size = (Births + Immigration) - (Deaths + Emigration)

Expressing Population Changes as a Percentage
Suppose we had a population of 100,000 individuals. Suppose in one year there were 1000 births, and 500 deaths.
What percentage of the population were births?
1000/100,000 = 0.01, or in percentage terms, this is 1% of the population.

What percentage of the population were deaths?
500/100,000 = 0.005, or in percentage terms, this is 0.5% of the population.

Assume immigration equals emigration. If so, then they cancel out of our population equation. We'll come back to
this assumption later.

Now, subtract deaths from births but express as a percentage:
1000-500/100,000 = 500/100,000 = 0.005, or 0.5% net growth

Thus, this population would be growing by 0.5% this first year. That means that after one year, there will be 500 more
individuals than the previous year. So, after one year, the population would be 100,500 individuals.

The Net Reproductive Rate
The net reproductive rate (r) is the percentage growth after accounting for births and deaths. In the example above, the population reproductive rate is 0.5%/yr.

Net reproductive rate (r) is calculated as: r = (births-deaths)/population size or to get in percentage terms, just multiply by 100.

Suppose we came back many years later, the net reproductive rate was still the same, but now the population had grown to 1,000,000. How many new individuals would be added each year now? Simply multiply the population by the reproductive rate:
1,000,000 x 0.05 (which is 0.5%) = 50,000

This means that now 50,000 new individuals are added in one year!! The net reproductive rate is the same as before, but because
the population is so much bigger, many more individuals are added.

Exponential Growth
If a population grows by a constant percentage per year, this eventually adds up to what we call exponential growth. In other words, the larger the population grows, the faster it grows!! A curve of exponential growth is an upward sweeping growth curve.

Plants lose water from their above ground surfaces in the process of transpiration. Most of this water is lost from stomata, microscopic openings in the leaves. Excess water loss can have a negative effect on the growth, development, and reproduction of a plant. Severe water loss can be fatal. Environmental factors have a major impact on the rate of plant transpiration. text...

Explanation:

The curve level off with an increasing percentage of open stomata per area of the leaf because the population decreases because of death. The unaffected plant species gain resources.

What is transpiration?

Plant roots absorb a considerable amount of water from the soil. This water travels to various parts of the plant via sap ascending. The entire amount of water absorbed by the plant exceeds its requirement.

Only a fraction of this water from vapor is absorbed by plant aerial parts such as (stem, leaves, buds, and flowers), which account for around 95% of total absorbed water. This is known as transpiration.

Therefore, because the population reduces due to death, the curve flattens out with an increasing percentage of open stomata per area of the leaf. Plant species that are not harmed gain resources.

How are the Hawaiian honeycreepers an example of adaptive radiation?



There were a large variety of honeycreepers that first inhabited the island. They found many different niches, so they were all able to survive.


The honeycreepers that first inhabited the island were able to adapt as the island changed, so that population of birds was able to survive.


There was a diversification of honeycreepers (each with different beak shapes) to help fill various ecological niches.

Answers

Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
