Intramuscular

Explanation:

Intramuscular is a method of administering injection directly into the muscles for effective functioning.

Long acting penicillin are administered intramuscularly because of penicillin sensitive microorganisms that are subsceptible to low serum levels which is associated with penicillin dosage in the body and penicillin Has low level of solubility therefore it is slowly released into the muscles sites.

A binucleate white blood cell would contain 92 chromosomes as it has two nuclei.

A white blood cell with two nuclei would have twice the amount of chromosomes as a regular white blood cell with a single nucleus. Typically, human white blood cells have 46 chromosomes.

If a white blood cell has two nuclei, it is known as a binucleate white blood cell, which means that it has two nuclei and twice the number of chromosomes as a single-nucleus white blood cell.

Therefore, a binucleate white blood cell would contain 92 chromosomes as it has two nuclei.

However, the number of chromosomes in white blood cells may vary depending on the type of white blood cell.

There are several types of white blood cells, including monocytes, neutrophils, eosinophils, basophils, and lymphocytes.

The number of chromosomes varies between these different types of white blood cells.

The relationship between a decomposer and a dead body is essential for the natural environment to be in balance. Decomposers such as bacteria, fungi, and scavengers break down the dead body, releasing nutrients and energy back into the environment.

This process is known as decomposition and it is essential for the cycle of life. Decomposers break down the dead body, releasing nutrients and energy back into the environment and so, preventing the buildup of waste. The nutrients released can be taken up by other organisms in the environment, including plants which then produce more food for animals.

This cycle of decomposition and nutrient release is essential for the balance of the environment. Without decomposers, dead bodies would accumulate and cause an imbalance in the environment, resulting in disease and death of other organisms.

The phylum Porifera contains the sponges, which are multicellular sessile organisms without a nervous, digestive, or circulatory system.

This means B, sponges, is the right answer.

Answer:

mitotic division

Explanation:

Answer:

Hyperviscosity will result in the decrease in blood flow which will increase the blood pressure in the individual.

This is referred to as the central organ of the circulatory system and is responsible for the pumping of blood and other types of substances to different parts of the body.

When the blood is hyperviscous, the blood becomes thicker and the heart requires more force to pump the blood to other parts of he body which therefore leads to an increase in the blood pressure of the affected individual.

This is why symptoms such as seizures, coma, or bleeding from their mucous membranes are experienced thereby making it the correct choice.

The correct sequence of events in cellular respiration is option a: glycolysis, citric acid cycle, electron transport chain.

During cellular respiration, glucose is broken down to produce energy in the form of ATP. The process starts with glycolysis, which occurs in the cytoplasm and involves the breakdown of glucose into pyruvate molecules. Glycolysis generates a small amount of ATP and NADH.

The pyruvate molecules produced in glycolysis enter the mitochondria, where the citric acid cycle, also known as the Krebs cycle, takes place. In this cycle, the pyruvate is further broken down, releasing carbon dioxide and generating NADH and FADH2 as electron carriers. The citric acid cycle also produces a small amount of ATP.

The electron carriers NADH and FADH2 then participate in the electron transport chain, which is located in the inner membrane of the mitochondria. In the electron transport chain, the electrons from NADH and FADH2 are transferred through a series of protein complexes, creating a flow of electrons that drives the synthesis of ATP. This process is known as oxidative phosphorylation.

Therefore, the correct sequence of events in cellular respiration is glycolysis, citric acid cycle, and electron transport chain, as stated in option a.

Explanation:

This question is impossible to answer without knowing exactly what is in the yellow tubing, regardless we can assume that the solution in the tubing with the yellow band is more concentrated than distilled water. This being the case then this will cause the distilled water to enter the tubing due to it being hypotonic to the solution within the tubing which means it has a higher concentration of water.

Answer:

C. The herd has reached its carrying capacity because the growth rate is negative.

Explanation:

The herd has not reached its carrying capacity because the growth rate is negative. Hence option c is correct.

Ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors. In ecosystems, biotic and abiotic factors or nonliving components coexist. Human welfare and survival depend on healthy terrestrial ecosystems because they give us access to critical goods and advantages.

Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. the three benefits that one organism might get by coexisting in a population with clumped dispersal. There is more access to food resources, less movement required for individuals to find mates, and improved predator protection for organisms.

Thus, the herd has not reached its carrying capacity because the growth rate is negative. Hence option c is correct.

DNA, RNA, ribosomes, pigments, cytoplasm, and prokaryotic and eukaryotic cells all contain these components.

There are mitochondria only in eukaryotic cells. Only eukaryotic cells contain the mitochondria, a cytoplasmic membrane-bound organelle. Mitochondria are not present in prokaryotic cells, which include bacteria and archaea.

They lack a nucleus, thus the genetic material inside each cell is free to move around. Furthermore, eukaryotic cells' many membrane-bound organelles are absent from prokaryotes. Prokaryotes lack mitochondria as a result. Some cell types, including red blood cells, are completely devoid of mitochondria. Bacteria and archaea are prokaryotic creatures and lack mitochondria.

When lawn mowers collect clippings, the drawback of this practice with respect to plant nutrition is that it reduces nutrient recycling in the soil.

Grass clippings are rich in nitrogen and other plant nutrients, making them an excellent natural fertilizer. Instead of collecting and disposing of them, you may use them as a beneficial ingredient in your lawn care strategy. Instead of expending money on commercial lawn fertilizers, returning grass clippings to the soil is an easy and inexpensive approach to enhance plant nutrition.

However, when you collect lawn clippings, you take away a significant quantity of organic matter and nutrients that would otherwise return to the soil and contribute to its fertility. By removing the clippings, you are reducing nutrient recycling in the soil, which can harm plant nutrition.

This may result in nutrient deficiencies, slower growth, and even pest or disease issues.Plant nutrition is important for the growth and healthy development of plants. Nutrient recycling is an important process for plants to derive necessary nutrients and this is hampered by collecting clippings. Hence, the drawback of this practice with respect to plant nutrition is that it reduces nutrient recycling in the soil.
