Which of the following describes an impact of floods on ecosystems?
Answers
Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.

Answers
Answer: The body systems that are involved are:
--> Nervous System and
--> muscular system.
Explanation:
The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:
--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.
--> The muscular system: This system enables the organism to move from one location to another.
Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.
The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
Answers
Answer:
Heat
Explanation:
Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.
Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.
What is metamorphic rock?Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.
Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

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

Answer:
Chromosomes contain genes, which help to determine an organism's traits. Genes come in alternate forms called alleles. The actual gene combination that an organism receives from its parents is called its genotype, while the trait that gets expressed as a result is referred to as its phenotype. If an offspring receives the same type of allele for a given gene from each parent, it is said to be h o m o z y g o u s. If the alleles differ, it is h e t e r o z y g o u s.

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).
Define the following and give an example of each.
