Answer:

Limits platelets population.

Explanation:

The result of this  modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body.

Answer: Protists

Explanation:

The protists are organisms which have characteristics similar to both plants and animals. There is huge diversity of protists on earth as they are single celled organisms and they increase in numbers by reproduction. They have a specialized cellular structure which includes organelles like nucleus, mitochondria, and others which are characteristic features of the eukaryotic organisms. They live in moist environment. They engulf their prey this way they are heterotrophic and they can also photosynthesize like plants.

This is parenchyma is found below the epidermis of plants and It of living cells that have thin cell walls which are loosely packed to accommodate the intracellular space. Parenchyma consist of chlorophyll and they take part in photosynthesis.

Xylem is called a permanent tissue because it contain various types of cells like tracheids, vessels, xylem fibres, xylem parenchyma which is responsible for storing food.

Answer: Paramedics are the medical professionals which perform multitasking in providing medical aid to the patients in the field as well as in the hospital.

Explanation:

Problems encountered by the paramedic at the accidental scene:

1. Major problem is the collection of the blood and other bodily fluids for examination as it is contaminated over spilling on the road.

2. Stabilizing and uplifting of the patient found on accident and curating them to ambulance is a labor consuming task.

3. Some body parts are severely damaged in accidents some of which includes those parts which covers the vital organs like ribs, spinal cord, skull, and pelvis so stabilizing those parts is a risky task for paramedics and can even kill the patient.

Answer:

presence of self replicating molecules

Answer:

The correct answer is - C. protein.

Explanation:

Ribosomes are biological molecules that are made up of RNA and proteins. These molecules produce protein molecules with the help of mRNA by the process of translation. These molecules are called the factory of protein or protein synthesis site.

The RNA that is present in these molecules is ribosomal RNA. These are attached to the other cell organelles called endoplasmic reticulum used the protein to check and modify them.

Answer:

pyruvic acid

Explanation:

Glycolysis involves the breaking of glucose molecule into two molecules of a 3-carbon compound called pyruvate (pyruvic acid) & two other molecules of ATP

Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons. Thus, option C is correct.

Glycolysis is the metabolic process by which glucose produces cellular energy, glycolysis is significant.

The most crucial source of energy for all living things is glucose. Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.

Most living things engage in some form of glycolysis. It represents the initial phase of cellular respiration.

It is a glycolysis route that results in the partial conversion of pyruvate from glucose. The common mechanism for both aerobic and anaerobic respiration is glycolysis.

Therefore, pyruvic acid is a 3-carbon molecule which is the final products of glycolysis.

D. There's a 50% chance the male will express the recessive trait

Explanation:

Because X is dominant over Xr, a female could not express it in this punnett square because she will have the extra X chromosome. While males do not have the extra X so if they receive the Xr they will have nothing to "cover" them.

Explanation:

Answer:

The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.

Explanation:

Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.

Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:

1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.

2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.

3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.

Answer:

Explanation:

A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. Less heat radiates into space, and Earth is warmer.

Answer:

Germline Mutations

Explanation:

Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)

Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
