Answer:
diluted genetic investment in offspring.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
Generally, asexual reproduction produces more reproductive offsprings than sexual reproduction, this is referred to as a reproductive handicap.
Hence, the reproductive handicap for sexual reproduction refers to diluted genetic investment in offspring.
This ultimately implies that, the sexually reproducing female would have a 50% genetic material passed to its female and male offspring.
However, sexually reproducing female has 100% transfer of her genetic materials through asexual reproduction.

A canyon is a small, deep valley with cliff-like sides. The Spanish word caon, which meaning “tube” or “pipe,” is where the term “canyon” originates. Thus, option A is correct.
What Canyons type of land features represented?A deep valley that has been carved into the surface of the earth over a long period of time by erosion from a flowing river is referred to as a canyon.
It is also referred to as a gorge and typically features rocky cliffs and very steep walls. One of the most well-known instances is the Grand Canyon, which the Colorado River carved out.
Canyon: A deep valley with steep walls and a V-shape created by a river slicing through hard rock. These valleys are common in the upper reaches of rivers, where the stream's fast, strong current rapidly digs the valley. Gorges are smaller valleys with a similar aspect.
Therefore, Although “gorge” is frequently used interchangeably with “canyon,” a gorge is nearly invariably narrower and steeper.

Arrange their 3 homologous pairs into Metaphase 1 (this will represent tetrads)
3. How many chromatids do you have?
RUBE
Answer:
Six pairs of chromatids.
Explanation:
There are six chromatids pair present if there are 3 homologous pairs of chromosomes because in each chromosome two chromatids are present. A chromatid refers to two identical halves of a replicated chromosome. Each chromatid has two arm like structure called telomere and these two chromatids are attached to one another from a point called centromere. So we can conclude that three pairs chromosomes have six pairs of chromatids.

Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: increased osmotic pressure in the filtrate that draws plasma through the membrane decreased osmotic pressure in the filtrate that increases the amount of filtration increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration neutral change in osmotic pressure with no effect on filtration
Answer:
The correct answer is ''increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration.''
Explanation:
Osmotic pressure is understood to be the force that must be applied to a solution when the flow of solvent needs to be stopped by means of a membrane with semi-permeable characteristics.Colloidal osmotic pressure in glomerular capillaries: it is the pressure exerted by proteins in the blood, which tends to recover the filtered water. To generate and maintain glomerular filtration, filtration pressure is required. That is, glomerular filtration is a physical phenomenon regulated by hemodynamic changes that affect the glomerulus and, although it is the initial excretion mechanism, it is not the exclusive regulator. Water, ions and some nutrients are mainly reabsorbed in the proximal tubule by different mechanisms. The water will follow a passive transport process by osmotic drag. The activity of the tubule is highly dependent on maintaining a fluid osmotic pressure similar to that of plasma. Since proteins and other elements that participate in the maintenance of the plasma osmotic pressure do not cross the glomerular barrier, in the tubule, the isoosmotic pressure with the plasma is fundamentally conditioned by the content of water and salt (dissociated as chlorine and Na +) of the ultrafiltered.
Cells and transport proteins are physically prevented from passing through the filtration membrane for this the correct answer is to increase osmotic pressure in the glomerular capillaries that reducing the amount of filtration.
Osmotic strain is known to be the pressure that needs to be carried out to an answer whilst the glide of solvent wishes to be stopped with the aid of a membrane with semi-permeable characteristics.Colloidal osmotic strain in glomerular capillaries: it's far the strain exerted with the aid of using proteins withinside the blood, which has a tendency to get better the filtered water. To generate and keep glomerular filtration, a filtration strain is required.What is glomerular filtration?That is, glomerular filtration is a bodily phenomenon regulated with the aid of using hemodynamic modifications that have an effect on the glomerulus and, even though it is the preliminary excretion mechanism, it isn't the different regulator.
Thus it is clear that the above answers are well explained.

Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?

Explanation:
Read the excerpt from How Hurricanes Form.
Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.
Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.
The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.

B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.
C. Scientists breed cows that give greater amounts of milk than their ancestors.
D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
Answer:
The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors
Explanation:
Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.
Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.

B) runoff will increase and less water will penetrate the soil to become groundwater
C) groundwater will puddle up and remain in one place instead of flowing to a central point
D) impervious surfaces such as roads and parking lots will divert water flow and it will not reach its endpoint
Answer:
B) runoff will increase and less water will penetrate the soil to become groundwater.
D) impervious surfaces such as roads and parking lots will divert water flow and it will not reach its endpoint
Explanation:
The runoff will increase and less water will penetrate into the soil to become groundwater if natural vegetation is replaced by impervious surfaces. The natural vegetation helps to lower the speed and intensity by absorbing large amount of water. Due to this absorbing, there is an increase occur in the concentration of groundwater level which increases underground water reserves for the coming generations. These impervious surfaces also act as a barrier that diverts water and prevents the water to reach to its ending point.

Why is the structure of a
nucleosome so important?
Answer:
In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression
Explanation:
In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.
