Answer:

Rotifers are specialists at living in habitats where water dries up regularly.

The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]

The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]

Explanation:

The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.

Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.

Answer:

Trophi (got it right on my quiz)

Explanation:

The trophi located behind the rotifer's mouth are responsible for crushing food.

The Air Quality Act was passed in 1967 and was the first federal air pollution control law that addressed the problem of interstate air pollution. The correct answer is b. Air Quality Act.

The Act gave the federal government the authority to regulate and control emissions of pollutants from stationary and mobile sources that contribute to air pollution that crosses state lines.

The Act also established the National Air Pollution Control Administration, which was later merged with other agencies to form the Environmental Protection Agency (EPA) in 1970. The EPA is responsible for enforcing the Air Quality Act and other federal air pollution control laws.

While the Air Quality Act was an important step forward in addressing interstate air pollution, it was later superseded by the Clean Air Act of 1970, which established more stringent air quality standards and more comprehensive regulatory authority over air pollution at the federal level.

Answer: Yield

Explanation: Yielding is an important traffic rule that promotes safety and smooth flow of traffic.  It is an important practice that helps maintain order on the roads and promotes safety for all road users. It's essential to be attentive, follow traffic signs and signals, and be aware of the right of way rules in your area to ensure a safe driving experience.

When you yield, you give the right of way to another driver or pedestrian. This means that you let them go first, even if it might inconvenience you or require you to slow down or stop.

Yielding is typically required in situations such as:

Yielding to pedestrians: When you approach a crosswalk or intersection where pedestrians are waiting to cross, you should yield to them and allow them to safely cross the road before you continue to drive.  Drivers must yield to pedestrians within a crosswalk.  

Yielding at intersections: When you approach an intersection where there are other vehicles, you should yield to those already in the intersection or approaching from the right. This helps prevent accidents and ensures a smooth flow of traffic.

Yielding when merging: When merging onto a highway or another lane, you should yield to the vehicles already in that lane. This allows for a safe and efficient merging process.

If a man who is a carrier of the sickle-cell trait and a woman who is also a carrier for the sickle-cell trait have a child, there is a 25% probability of that child suffering from sickle-cell anemia.

Sickle-cell anemia is an autosomal recessive genetic disorder that is caused by a mutation in the HBB gene, which codes for the beta-globin subunit of hemoglobin. People who are carriers of the sickle-cell trait have one normal copy of the HBB gene and one mutated copy, and they are typically asymptomatic. However, if both parents are carriers of the sickle-cell trait, there is a 25% chance that their child will inherit two mutated copies of the HBB gene, one from each parent, and will therefore develop sickle-cell anemia. There is a 50% chance that the child will be a carrier of the sickle-cell trait like the parents, and a 25% chance that the child will inherit two normal copies of the HBB gene and will not have sickle-cell anemia nor the sickle-cell trait.

The two things which interfere with an enzyme's ability to speed up a chemical reaction are the temperature and pH condition.

The enzyme activity refers to the number of moles of the product which are formed per unit of time. The enzyme activity and the concentration of the enzyme can help in determining the specific activity of the enzyme in a reaction. The specific activity is the ratio of the enzyme activity to the concentration of enzyme.

Several factors which affect the rate at which enzymatic reactions proceed include temperature, pH, enzyme concentration, substrate concentration, and the presence of inhibitor molecules or activators.

Biologists refer to dominant alleles as uppercase letters and recessive alleles as lowercase letters when referring to genotype.

Genetics and evolution define an allele as a variant of the same sequence of nucleotides at the same location on a lengthy DNA molecule.

The variant DNA sequences at a locus are known as alleles, and the chromosomal or genomic location of a gene or any other genetic element is referred to as a locus.

Alleles can be identified using just one capital or lowercase letter, two, three, or more letters, or letter/number combinations. Superscripts, subscripts, or both may be present in alleles.

Alleles that are recessive are denoted by lowercase letters, while dominant alleles are denoted by capital letters.

Thus, this way, the alleles are represented.

The three types of capillaries in order from the least permeable at top to most permeable at the bottom are Continuous capillaries,Fenestrated capillaries, Sinusoidal capillaries.

The three types of capillaries can be arranged from least permeable to most permeable as follows:

Continuous capillaries: Continuous capillaries have the least permeability. They have tight junctions between endothelial cells that limit the passage of most solutes and macromolecules. Only the smallest solutes, such as water, ions, and lipid-soluble substances, can pass through the endothelial cells or through small gaps called intercellular clefts.

Fenestrated capillaries: Fenestrated capillaries are more permeable than continuous capillaries. They have small pores or fenestrations within the endothelial cells, allowing the passage of small solutes and macromolecules. Fenestrated capillaries are found in tissues that require rapid exchange of substances, such as the kidneys, endocrine glands, and intestines.

Sinusoidal capillaries: Sinusoidal capillaries are the most permeable type of capillaries. They have large irregular gaps between endothelial cells, wide intercellular clefts, and discontinuous basement membranes. This structural arrangement allows for the passage of large solutes, cells, and proteins. Sinusoidal capillaries are primarily found in organs with high metabolic activity, such as the liver, spleen, and bone marrow.

The link between adenosine diphosphate (ADP) and adenosine triphosphate (ATP) is best explained by the fact that when energy is added, ADP interacts with a phosphate group to form ATP. The right Option is (c).

The mitochondria of cells are thought of as the powerhouse since ATP is produced there. As seen in the reaction below, ATP is produced when ADP reacts with an inorganic phosphate and an energy source to generate ADP;

Pi + energy + ATP + H2O = ADP + inorganic phosphate

One adenine, one sugar, and two phosphates make up the biological molecule known as adenosine diphosphate (ADP). Its most crucial function is the creation of ATP, the most vital energy molecule in living cells, when it is coupled with a phosphate molecule. An enzyme called ATP synthase produces ATP during oxidative phosphorylation. Specifically, protons travel through the protein and cause a conformational change once a proton gradient is established. ADP and inorganic phosphate are then combined by ATP synthase to form an ATP molecule.
