As Hite and Seitz (2016) discuss in Chapter 5: Climate Change, reputable scientific studies continue to show that the Earth is warming at an unsustainable rate because of a rise in the release of CO2 and methane gases. What is the relationship between population increases and climate change
Answer:
See the answer below
Explanation:
The relationship between climate change and increased population of humans is a direct one. As the population of humans increases, their activities leading to the release of greenhouse gases such as CO2 and methane also increases. The greenhouse gases are primarily responsible for the warming of the earth.
As more and more greenhouse gases are released into the atmosphere, more radiation from the sun is trapped in the atmosphere and the earth receives more warmth. This extra heat received leads to increase in the global temperature, a phenomenon known as global warming. As the average global temperature increases, climate becomes more erratic and unpredictable.
The greenhouse gases-related activities of humans that are bound to increase with the increase in population include deforestation, fossil fuel burning, industrialization, etc.

What is nutrient cycling?Nutrient cycling is the process by which nutrients are transformed, transported, and exchanged between different parts of an ecosystem. Nutrients are essential for the growth and survival of all living organisms, and they are constantly being recycled through various processes in the environment.
For example, plants absorb nutrients from the soil and water, and then animals consume these plants and incorporate the nutrients into their own bodies. When animals die, their bodies decompose, releasing the nutrients back into the soil or water, where they can be taken up by plants again. This continuous flow of nutrients between living organisms and the environment is known as nutrient cycling.
Nutrient cycling is important because it helps to maintain the balance of nutrients in an ecosystem and supports the functioning of the ecosystem as a whole. It is influenced by many factors, including geological processes, weather patterns, and the actions of living organisms.

Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable autosomal dominant genetic disease, in an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible not all offspring will receive the abnormal allele from an affected heterozygous parent.
Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease.
Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease.
Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
As it is given that Mark's paternal grandmother and grandfather does not carry the disease. The symbols on the right side of the Punnett represent Mark's paternal family. If both his paternal grandparents are unaffected then his father and paternal aunt are also not affected by the disease.
His maternal grandfather is affected as mentioned and also his maternal aunts are affected. Mark's mother is unaffected as she does not have the disease-causing alleles determined by genetic testing.
Both of the marks parents are unaffected which indicates that marks also do not carry the allele of the disease.
Huntington's disease is an autosomal dominant disorder in which the presence of even one dominant allele can cause the disorder.
The autosomal disorder can not skip a generation, have to be present in every generation.
Condition Given:
Affected Member: Mark's Maternal grandfather and Maternal aunts.
Normal: Mark's Maternal grandmother and Mark's Mother.
As MArk's Maternal Grandfather is affected then his genotype must be Aa because Mark's Maternal grandmother is unaffected (aa), this is the only condition where Mark's mother will be normal.
A- Dominant (Huntington)
a- Recessive
Maternal means on the mother's side and paternal means on the father's side.

a. reflex arc associated with vasomotor fibers
b. reflex arcs involving baroreceptors
c. altering blood volume
d. centers in the medulla oblongata and the pons
Answer:
c. altering blood volume
Explanation:
The sympathetic nervous system acts to modulate blood pressure during short-term periods by modifying arterial pressure. The catecholamine hormone levels may be associated with an increase in the blood pressure by narrowing the blood vessels. Catecholamines are hormonal neurotransmitters released by the adrenal glands. These hormones derive from the metabolism of tyrosine amino acids and include, among others, adrenaline, noradrenaline and dopamine.

b) Insulin mediates glucose uptake in the brain
c) "Prediabetes" is a condition characterized by an increased risk for the future development of type 2 diabetes
d) The rise in insulin concentration after meal ingestion is reduced in type 1 but not in type 2 diabetes
Answer:
C) Prediabetes is a condition characterized by an increased risk for the future development of type 2 diabetes.
Explanation:
Prediabetes is a condition where there's a higher than normal blood sugar level but not high enough to be classified as type 2 diabetes. It is most likely to progress to type 2 diabetes if there are no lifestyle changes to mitigate the risk.
This progression can be stopped if the necessary lifestyle changes such as physical exercise, eating a healthy diet, weight control etc, are implemented.
Prediabetes doesn't usually present with any signs and symptoms though one possible sign is the darkening of the skin on the neck, armpit and elbows.
When signs like frequent urination, excessive thirst and fatigue are noticed, it is most likely the onset of type 2 diabetes.

The first glycolysis rate-limiting enzyme is under various allosteric regulations. This protein is nearly inactive because of inhibition by ( ) under physiological conditions. The activity is restored by ( ), its most potent allosteric activator.
a. AMP :::: citrate
b. AMP :::: Fru-2,6-P2
c. ATP :::: citrate
d. ATP :::: Fru-2,6-P2
e. All of these
Answer:
d. ATP; Fructose-2,6-bisphosphate
Explanation:
Phosphofructokinase-1 is the enzyme that catalyzes the formation of fructose-1,6-bisphosphate from fructose-6-phosphate and ATP. The phosphofructokinase step is the first rate-limiting step of glycolysis.
Phosphofructokinase-1 activity is allosterically regulated. Its activity is increased whenever the cell's ATP supply is depleted or when its breakdown products, ADP and AMP accuulates in he cell. However, it is inhibited when the cell is amply supplied with ATP.
The activity of phosphofructokinase-1 is restored by fructose-2,6-bisphosphate, its most potent activator.
From the given options:
a. AMP :::: citrate is wrong because AMP increases the activity of phosphofructokinase-1 and citrate is not its activator but an inhibitor
b. AMP :::: Fru-2,6-P2 is wrong because AMP increases its activity same as fructose-2,6-bisphosphate
c. ATP :::: citrate is wrong because both citrate and ATP are inhibitors
d. ATP :::: Fru-2,6-P2 is correct as explained above
e. All of these is wrong because of the other wrong options above.

Answer:
Death of organism
Explanation:
Human activities include the clear-cutting of areas of forest to make space for farming.
Which effect is most likely to occur as a result of clear-cutting?
Is this your question?
Death of organisms effect is most likely to occur as a result of clear-cutting.
What do you mean by clearcutting?Clearcutting is an extreme logging method in which resilient natural forests are harvested and replaced with man-made tree plantations that do not replicate the ecosystem services of a healthy forest.
Clearcutting is one of the most publicly maligned and misunderstood forest regeneration treatments. It is the only way to grow trees that require full sunlight to reproduce, such as tulip poplar, black cherry, and aspen, and the fastest way to provide/create shrubland habitat.
Clear-cutting often contributes to reductions in root strength and soil water-holding capacity, due to soil compaction and reduced transpiration. Moreover, the removal of the forest cover exposes the soil surface to heavy precipitation and large variations in temperature.

After duplication, at what point does a cell become two cells with identical DNA? starting in prophase end of anaphase end of cytokinesis
Answer:
The correct answer is - end of cytokinesis.
Explanation:
Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.
During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA
The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.
Thus, the correct answer is - end of cytokinesis.
