Answer:
(I) pancreas - it secretes insulin
it's function is to regulate the sugar levels in blood
if it does not function properly it causes diabetes (sugar)
(ii)pituitary- it secrets growth hormone
it's function is to regulate the growth in human body
if it produces lots of hormone then the body will increase a lot in size known as gigantism
if it produces very less hormone then the body will not increase in size and will be very short known as dwarfism
(III)thyroid gland-it secretes thyroxin
its function is to maintain metabolism growth
lack of iodine makes this gland swell up known as goitre.
(iv)Adrenal gland - it secrets adrenaline
it's function is to help us prepare and respond to stressful situations
because of its malfunction the body does not get enough hormones.

Because of high increases in populations, some underdeveloped countries are already exceeding their carrying capacity. They cannot produce enough food to support their populations. These regions are undergoing very rapid desert formation. Growing populations contribute to this by clearing forests for agriculture and firewood. Which region in the table is most likely experiencing desert formation? Explain.
Hint: Think about where the population is increasing the most quickly.
Answer:
Africa is most likely experiencing desert formation because it's annual growth rate is the highest of them all.
In the given scenario, Africa is most likely experiencing desert formation as it is having highest growth rate percent.
What is growth rate?The average annual rate of change in population size for a given country, territory, or geographic area over a given time period.
As the given regions are undergoing very rapid desert formation, Africa would go through this process, as it is having highest growth rate.
Thus, the answer is Africa.

Describe two pathways the student can use to show how a metamorphic rock
could become another type of rock and then become metamorphic once again
Answer:
In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.
Explanation:
hope this helps
Answer:
One pathway is that an igneous rock can apply heat and pressure to the rock which will become metamorphic. Another pathway is that a metamorphic rock can be changed by heat and pressure to form into a different metamorphic rock.

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fibrosis and isn't a carrier. Use F to denote the normal allele and f to denote the mutated CFR allele. What percentage of their children are likely to have cystic fibrosis? What percentage of their children are likely to be carriers of cystic fibrosis?
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF". The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.

Answer:
A) A nucleus
Explanation:
Nucleus is the structure that all eukaryotic cells contain as represented by the diagram. Nucleus is present inside the cell and located in the center of the cell.
What is nucleus?Nucleus is defined as a membrane that is enclosed cell organelle inside a cell and it contain chromosome.The main function of nucleus is to regulate and controls the activities of the cell. It is also known as brain of the cell as it regulates and controls all the function of the cell.
The structure of nucleus is that it contains a structures such as nuclear envelope, nucleoplasm, or it is also known as nucleus sap or nuclear matrix, nucleolus and chromatin.
Nucleus stores the DNA of the cell and maintain its integrity, and provide it for the process of transcription, traslation and replication.
The nucleus contain nucleolus and the region is black and chromosomes have beeds like structure on them and they are known as genes that helps to pass a particular character from one generation to other generation.

How can an abiotic factor like temperature impact the population size of an ecosystem
Answer/Explanation:
Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.
They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.
If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.

Why the tropical forest has a more lush plant life than the tundra in regards to how fast things decompose.
Answer:
Because of Nitrogen
Explanation:
Nitrogen seems to be much difficult for plants to acquire because they can only consume nitrogen when it is combined with oxygen or hydrogen, which is why tropical forests have a lusher plant growth than tundra.The decomposition process is the secret to maintaining the nitrogen cycle going since the bulk of fixed nitrogen arrives from decaying organisms and faces being broken down by bacteria.What do igneous rocks that undergo weathering and erosion become?

Which of the following is(are) non-technological ways of improving air quality?
a. using public transportation
b. building wind turbines
c. turning lights off when leaving a room
d. both a and c
Using public transportation and turning lights off when leaving a room are both non-technological ways of improving air quality. Therefore, (A) and (C) are correct.
What is air quality?An air quality index is a tool that is used by government agencies to communicate with the general public about the current level of air pollution as well as the level of air pollution that is expected to occur in the near future.
The Clean Air Act regulates a number of key air pollutants, including ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The AQI is determined based on these four pollutants. The Environmental Protection Agency (EPA) has developed national air quality standards to safeguard the general population from each of these contaminants.
We can improve the quality of the air by:
Try to cut down on the amount of times you drive your vehicle.Use of fireplaces and wood stoves should be cut back or eliminated entirely.Avoid burning anything, including leaves, rubbish, or other objects, on fire.Try to avoid using lawn and garden equipment that is powered by gas.Learn more about AQI, here;
