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.

Answer:

This is the Ventral Regulatory Group-VRG

Explanation:

In the medulla,there are four groups of neurons which forms the exhalation parts of the   respiratory  control.These 4 groups are called the VRG.They occupy 5mm anterior in length, and laterally positioned to the dorsal respiratory group.They are therefore said to occupy the ventrolateral part of the medulla.

The dorsal respiratory group(DRG) consists of the inspiration neurons,contrary to the VRG. They do not extend to the DRG,but the DRG, extends to them

They(VRG) function in propagating action potentials needed for the mechanisms of respiration.(exhalations), and Inspirations

Long-term environmental changes can have various effects on the organisms and ecosystems that inhabit them, and one possible effect is habitat loss, which is the third option.

Long-term environmental changes are changes that occur gradually over time, such as changes in temperature, rainfall patterns, or atmospheric conditions, and can have significant impacts on ecosystems and the organisms that inhabit them. One of the primary effects of long-term environmental changes is habitat loss. For example, climate change is leading to melting ice caps, rising sea levels, and changes in weather patterns, which can impact habitats such as coral reefs, forests, and wetlands, causing them to shrink or disappear. This can result in the loss of habitat for many species, leading to declines in their populations and potential extinction.

Hence, long-term environmental changes can have various effects on the organisms and ecosystems that inhabit them, and one possible effect is habitat loss, which is the third option.

The process that involves wind moving loose sediments is the deflation. Deflation is further described below.

Deflation is a type of wind erosion that involves the displacement of movement of loose materials from flat dry and non cemented surfaces such as the deserts and dry lakes.

The wind is the major factor that causes deflation in wind erosion, therefore the stronger the wind the bigger the pieces of sediments the wind can pick up.

D. atoms to be rearranged into new substances.

Explanation:

Chemical reactions involve interaction between chemicals such that all reactants are changed into new materials. The properties of the new materials are different from those of the reactants.

Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.

Answer: The expected frequency of carriers is P(Aa)=0.046.

The proportion of childs with CF is P(aa)=0.024.

25% of having a child with CF (aa).

Explanation:

Hardy-Weinberg's principle states that in a large enough population, in which mating occurs randomly and which is not subject to mutation, selection or migration, gene and genotype frequencies remain constant from one generation to the next one, once a state of equilibrium has been reached which in autosomal loci is reached after one generation. So, a population is said to be in balance when the alleles in polymorphic systems maintain their frequency in the population over generations.

Given the gene allele frequencies in the gene pool of a population, it is possible to calculate the expected frequencies of the progeny's genotypes and phenotypes. If P = percentage of the allele A (dominant) and q = percentage of the allele a (recessive), the checkerboard method can be used to produce all possible random combinations of these gametes.

Note that p + q = 1, that is, the percentages of gametes A and a must equal 100% to include all gametes in the gene pool.

The genotypic frequencies added together should also equal 1 or 100%, and all the equations can be summarized as follows:

[tex]p+q=1\\(p+q)^{2} = p^{2} +2pq+q^{2} = 1\\P(AA)=p^{2} \\P(aa)=q^{2} \\P(Aa)=2pq1[/tex]

So, there are 1700 individuals and only one is affected. Since it is a recessive disorder, the genotype of that individual must be aa. So the genotypic frequency of aa is 1/1700=0.000588.

Then, [tex]P(aa)=q^{2}=0.000588[/tex]. And with that we can calculate the value of q,

[tex]P(a)=q=\sqrt{0.000588}=0.024[/tex]

And since we know that p+q=1, we can find out the value of p.

[tex]p+0.024=1\\1-0.024=p\\p=0.976[/tex]

Next, we find out the genotypic frequency of the genotype AA:

[tex]P(A)=p=0.976\\P(AA)=p^{2} = 0.976^{2}=0.95[/tex]

Now, we can find out the genotypic frequency of the genotype Aa:

[tex]P(Aa)=2pq=2 x 0.976 x 0.024 = 0.046[/tex]

Notice than:

[tex]p^{2} + 2pq + q^{2} = 1\\x^{2} 0.976^{2} + 2 x 0.976 x 0.024 + 0.024^{2} = 1[/tex]

Then, the expected frequency of carriers is P(Aa)=0.046

The proportion of childs with CF is P(aa)=0.024

If two parents are carriers, then their genotypes are Aa.

Gametes produced by them can only have one allele of the gene. So they can either produce A gametes, or a gametes.

In the punnett square, we can see that there genotypic ratio is 2:1:1 and the phenotypic ratio is 3:1. So, there is a probability of 25% of having an unaffected child, with both normal alleles (AA); 50% of having a carrier child (Aa) and 25% (0.25) of having a child with CF (aa).

Answer:

c. -0.78

Explanation:

Correlation coefficients are used to measure the relationship between two variables.  correlation coefficients lies between -1 and +1.

Correlation coefficients greater than zero indicates positive correlation, less than zero indicates negative correlation and zero shows no relationship between the two variables.

Large positive or negative correlations have very less chances to occur, so large negative correlation will have less chances to occur because sampling variation gives large negative correlation by chance.

Hence, the correct answer is c. -0.78.

The matrix can be used to detect the expression of the target gene

Explanation:

DNA probes enable to identify target acid nucleic sequences (i.e., DNA or RNA) that are capable of hybridizing with the probe. The probe is usually labeled with different 'detectors' (i.e., radioisotopes, fluorophores, epitopes, etc), thereby allowing its detection by observing the response to the hybridization process. For example, a DNA microarray can be used to detect simultaneously the expression of thousands target genes.

The conclusion related to the sequence of baby DNA fragment should be that the matrix is used for detect the expression of the target gene.

The probe of DNA should enable for identifying the target acid nucleic sequences. Also, it should be labeled along with the distinct detectors. Also, it permits detection by observing the response to the hybridization process.

Explanation:

With the practice of exercise and a well-balanced diet, what usually happens is an increase in lean mass, associated with the loss of body fat.

This gain of lean mass mainly with people who practice resistance and strength exercises, such as weight training and Crossfit.

The bodyweight remains unchanged, even if the individual's body measurements change. That is since muscle mass weighs more than fat mass, with less volume.

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.

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.

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

Answer:

The correct answer is - hypogastric region.

Explanation:

The hypogastrium (additionally called the hypogastric region or suprapubic locale) is an area of the abdomen situated beneath the umbilical region. The pubis bone comprises its lower limit. The underlying foundations of the word hypogastrium signify "beneath the stomach"; the foundations of suprapubic signify "over the pubic bone".  

The hypogastric region (beneath the stomach) contains the organs around the pubic bone. These incorporate bladder, some portion of the sigmoid colon, the anus, and numerous reproductive organs, for example, the uterus and ovaries in females and the prostate in guys.

Thus, the correct answer is - hypogastric region.
