There are no cells in viruses. The genetic material they possess is shielded by a protein sheath (either DNA or RNA).

Nucleic acid (the genome) and protein are the two primary components of infectious viral particles. All viruses that have an envelope also have lipid in the envelope and carbohydrates in their glycoprotein peplomers (as well as that in the nucleic acid).

In virology, viruses choose a protective protein coat over the cell walls that certain living things have in place of the nucleic acid. This kind of covering is known as a capsid.

A species that can change the composition of an entire community based solely on the strength of its biotic interactions is called keystone species.

Abiotic interactions in plants are a straightforward example. For plants to grow, they require water, sunshine, and carbon dioxide. The connection between organisms occurs when plants use a process known as photosynthesis to produce their own food using water, sunshine, and carbon dioxide.

In terms of relationships between organisms, we use the term "biotic interactions." They may be intraspecific (among individuals of the same species) or interspecific (between members of different species). An antagonistic connection is one in which at least one of the interactants suffers harm.

The male sperm never fertilizes the female egg despite the parrots' repeated mating. Gametes mate, yet they are unable to combine. This is an illustration of a prezygotic reproductive barrier known as gametic isolation.

The process through which one species divides into two or more species is known as adaptive radiation. Different populations become reproductively isolated from one another as a result of adjusting to various circumstances, which typically happens.

By means of speciation, which occurs when an ancestor population divides into two or more genetically separate descendant populations, new species are created. Within the original population, speciation entails the reproductive isolation of groups and the development of genetic variations between the two groups.

The form of enzyme regulation described is called "proteolytic activation."

Proteolytic activation is a common mechanism for regulating enzymes, particularly digestive enzymes. In this mechanism, an enzyme is produced in an inactive form (called a zymogen or proenzyme) and must undergo a specific cleavage event to become active. In the case of chymotrypsin, it is produced in an inactive form in the pancreas and only becomes active in the intestines after being cleaved by trypsin. This ensures that the enzyme is not active in the pancreas where it could potentially harm the pancreas itself or other tissues. This mechanism of enzyme regulation is important for maintaining proper digestion and preventing damage to the body.

Answer:

It is not possible to put a figure as to how much the atmospheric carbon will change in one, 10, or even 100 years.

The change in the atmospheric carbon fluctuates based on certain factors:

How much carbon is released to the atmosphere both by natural processes and human activities

How much carbon is removed from the atmosphere based on both natural processes and human efforts.

It is not really possible to predict exactly how humans will behave or what natural processes will happen. Hence, it becomes really difficult to put a figure on how much the atmospheric carbon will change with time.

The global atmospheric carbon was 409.8 ± 0.1 PPM in 2019 and this figure represents an increase of 2.5 ± 0.1 PPM from the previous year. If the latter figure is anything to go by, it means that an increase of 2.5 ± 0.1 PPM happens annually. That would be an increase of 25 PPM in 10 years and 250 PPM in 100 years to come.

Environmental and occupational health (EOH) practitioners need a firm grasp of basic epidemiological principles in their daily work as epidemiological principles help EOH practitioners to recognize and analyze disease patterns and patterns of exposure to environmental contaminants that cause disease.

Epidemiology is the study of how diseases spread and how to prevent or treat them. EOH practitioners must know the science behind disease transmission and prevention, as well as how to perform public health surveillance and risk assessments.

EOH practitioners work in a wide range of settings, including hospitals, local health departments, state and federal government agencies, and academia. They often work with colleagues from various disciplines such as toxicology, biostatistics, and environmental science, among others. They use a range of epidemiological tools to investigate environmental and occupational health hazards that can affect human health. They must also understand the statistical methods used to analyze and interpret data obtained from epidemiological studies.

Answer:

DNA consists of two complementary strands which runs anti parallely to each other and forms a helix like structure due to their twisting angle geometry\(.\)

Complementary strand means, if you are given the nitrogenous base sequence of any one strand, you can easily find the sequence of other strand by the simple rule of "A binds with T and C binds with G" i.e. purine binds with pyrimindines in other words.

When threatened North American Millipedes roll into a ball to protect their undersides that are the most vulnerable part of their bodies. Unlike  millipedes are relatively slow creatures who like to travel at their own pace.

Predation is defined as a biological interaction where one organism, the predator, kills and eats another organism, its prey.

Millipedes release a harmful substance (toxin) all over their body if they are threatened or if you handle them roughly. The toxin which millipedes release keeps away most predators. Some large millipede species can spray these toxins as far as 33 inches (81 cm).

Answer:

C. On earth's surface directly above the initial rock slippage

Explanation:

A fault occurs when the earth's crust breaks because two blocks slip in a way that affects each other. Transform fault is a type of strike-slip fault that occurs when the two blocks slip in a horizontal manner alongside each other. hen earthquakes occur around transform faults, the depth is not very deep rather the earthquakes will occur at shallow depth.

Epicenters of earthquakes usually occur close to the surface of the earth. Therefore, the epicenter of a transform fault would occur on the earth's surface directly above the initial rock slippage.        

An ectopic pregnancy is basically a complication in which the fertilized ovum is implanted in any tissue other than the uterine wall.

Hence, the correct option is option c.

The pregnancy basically begins with a fertilized egg. Normally, this fertilized egg attaches to the uterine wall. An ectopic pregnancy is said to have occurred when the fertilized egg gets implanted and also grows outside the main cavity of the uterus.

An ectopic pregnancy most commonly occurs in a fallopian tube, which performs the function of carrying the eggs from the ovaries to the uterus. This type of ectopic pregnancy is known as tubal pregnancy. Sometimes, an ectopic pregnancy can also occurs in other areas of the body, like the abdominal cavity, ovary, or the lower part of the uterus, which is the cervix, which connects to the vagina.

Fossil fuels are burned to produce energy. Power plants burn coal or oil to build heat that is consequently used to make steam to drive turbines which generate electricity.

Answer - Solid fosiil fuel formed from decay of land vegetation or plant remains. Produces energy when burned.

In a population with random gamete selection but is small, there is a higher chance of genetic drift occurring. Genetic drift is the random fluctuation of allele frequencies in a population due to chance events. In a small population, these chance events can have a larger effect on the overall genetic makeup of the population, leading to a loss of genetic diversity and potentially causing certain alleles to become fixed in the population.

In contrast, a larger population with random gamete selection is less likely to experience genetic drift, as the effects of chance events are diluted by the larger number of individuals. As a result, there is a greater chance of maintaining genetic diversity and preventing certain alleles from becoming fixed in the population.

Overall, the main difference between a small population with random gamete selection and a larger population with random gamete selection is the likelihood of genetic drift occurring and its potential effects on the genetic makeup of the population.
