Explain how enzymes work, including the role of the enzyme-substrate complex.

In some angiosperm plants, pollen grains express spikes on their surface that help them stick to the pollinator's body and incrceases the chances of cross-fertlization. Option B. Angiosperm.

Different families among the Angiosperm group produce pollen with spikes on their surface.

This is a strategy developed by these plants to ensure cross-fertilization. Let us remember that pollen is the masculine cell released by the masculine organ of the plant. This cell meets the ovocell and fertilize.

In cross-fertilization, pollinators play an important role since they carry pollen from one plant to another one.

To ensure pollen sticks to the pollinator's body and succesfully get to another flower, Angiosperm developed spikes that help the grain to  cling to the pollinator's body. Once the insect get to the new flower, pollen is deposited, increasing the chances of cross-fertilization.

The correct answer is b. Angiosperm

You will find the table that provides data about the two species in the attached files.

Answer:

Because in the table provided you can see that, even when both species can use the same resources, certain vegetable species are eaten only by buffalo and not by cattle, while some other plants are eaten by cattle and not by buffalo.

Explanation:  

The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the interaction with other species.

The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.

Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrate or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.

In the exposed example, cattle and buffalo share the same fundamental niche, meaning that both of them can consume the same vegetable species, although in some cases, cattle eat certain species that buffalo does not, and vice-versa. Probably it occurred resource partitioning between these species, reflected in the fact that buffalo feeds on some species, while cattle feed on some other species.

Answer:

E) Methylation of the N-terminal tails of nucleosomes typically results in decreased transcription and more tightly packed chromatin.

Chromatin condensation may be facilitated by methylation of histone tails. In chromatin, acetylation of histone tails gives transcription access to DNA. Some types of chromatin modification can be transmitted to subsequent cell generations.

One of the most prevalent epigenetic regulations that plays a significant role in both developmental processes and diseases is histone methylation. By altering the chromatin architecture, the methylation status of lysine residues in histone proteins determines the active and silent states of surrounding genes.

Systosolic blood pressure

Explanation:

The systosolic blood pressure occurs when the heart is contracting and pushing the blood round the body. It is more important than diastolic blood pressure.

When the heart beats, it contracts and pushes blood through the arteries to the rest of your body.

This force creates pressure on those blood vessels which are the arteries, producing the systolic blood pressure as compared to diastolic blood pressure that measures the lowest block pressure between heartbeats.

Answer:

We would gradually decay, and it would be horrific, and if new cells contiued to form it would also be pretty horrific

Explanation:

If we reached maturity while old cells never died off , this would heighten the risk for genetic and hereditary disorders, and new cells are not formed through mitosis, and are unable to replace inefficient or cells with damages, whether it not be to the DNA or other organelles.This would cause a significant decline of production in our body, and would also cause cells such as your skin cells, to be at a heightened risk of genetic and hereditary disorders and diseases such as cancers and melanomas

If our cells continued to form while old ones never died off, if would also be very inefficient for our bodies, as the amount of energy and ATP required to support an ever-growing cell population of that size would leave us wanting to eat more and more each day to fufill our daily metabolic processes, leaving us skinny and weak.This would also cause a loss of some function in some areas, because some areas require more energy than others, such as your pulmonary and cardiovascular system, and could result in wasting of muscle tissure, as they would not be getting the nutrients needed

If new cells would stop forming once maturity is reached, and old cells would never die. Genetic disorders would be more common, cells with damage would not be replaced, hereditary disorders would also be more common, such as cancers and others. If new cells continued to form and old cells would never die off, the amount of energy that is required to normally support us would leave us wanting more food each day to achieve our metabolic process.

The significant number of rat population being killed by an earthquake on the newly discovered planet of Paeleoland can be characterized as a density-dependent factor influencing the growth regulation of the rat population.

Density-dependent factors are environmental factors that have a greater impact on population growth as population density increases. In this scenario, the earthquake-induced mortality affecting a significant number of rats would directly influence the population density and have implications for the growth regulation of the rat population on Paeleoland.

The earthquake would lead to a sudden reduction in the rat population, creating a decrease in population density. As a result, the availability of resources and competition for those resources may change. With fewer rats, there would be less competition for food, shelter, and other essential resources, potentially leading to increased survival and reproductive success for the remaining individuals. This could contribute to a period of population growth as the population rebounds from the initial decline.

Furthermore, the decreased population density could also result in reduced intraspecific interactions such as competition and territoriality, which may further promote population growth. Over time, if the population size increases and approaches carrying capacity, density-dependent factors such as resource limitation or increased competition could once again regulate the population growth and stabilize it at a sustainable level.

Answer: OD

Explanation: OD. Due to the complementary nature of base pairing, elongation is paused when DNA polymerase adds the wrong nucleotide. The structure of DNA helps prevent errors from occurring during DNA replication by the complementary base pairing of the nucleotides. If DNA polymerase adds the wrong nucleotide, the base pairing will be disrupted, causing elongation to pause and allowing for correction mechanisms to remove the incorrect nucleotide and replace it with the correct one, reducing the number of errors that occur during replication.

An ontogenetic explanation is a sort of biological explanation that explains how a certain behavior or feature develops within a person or species. An ontogenetic explanation in the setting of a species could explain the existence of a behavior by demonstrating how that behavior improved the species' reproductive success through time.

A behavior that improves a species' chances of obtaining food, avoiding predators, or luring mates, for instance, could offer a selection advantage, causing that behaviour to evolve and change through successive generations. Researchers can learn more about ontogenetic evolution of manner and how such behaviors serve an adaptive purpose in a specific species by examining the ontogenetic development of those behaviors.

False. Natural selection is not defined as the differential survival and reproduction of a population’s individuals that are genetically identical.

Natural selection is the process by which populations of organisms evolve over time due to differential survival and reproduction of individuals with certain traits. These traits are often determined by the organism's genes, and individuals with traits that are better suited to their environment are more likely to survive and reproduce than those with less advantageous traits.

However, natural selection does not require that individuals within a population are genetically identical. In fact, genetic variation is a key component of natural selection, as it provides the raw material for evolution to occur. Different individuals within a population may have slightly different genetic variations, and the traits associated with these variations can lead to differences in survival and reproductive success.

Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.

Explanation:

In the beta globin gene, an adenine takes the place of a thymine, which causes valine to take the place of glutamic acid in the hemoglobin protein. This form of mutation is a base substitution. Option c is Correct.

Base substitutions, the most basic kind of gene-level mutation, occur when one nucleotide is exchanged for another during DNA replication. For instance, a thymine nucleotide may be substituted for a guanine nucleotide during replication.

A single nucleotide can be replaced with a different nucleotide in a mutation called a substitution mutation. Examples of base-pair substitutions include replacing one purine (A G) with a different purine or one pyrimidine (C T) with a different pyrimidine. Option c is Correct.
