The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. In population biology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium. Its effect on population dynamics may be approximated in a logistic model, although this simplification ignores the possibility of overshoot which real systems may exhibit.

Carrying capacity was originally used to determine the number of animals that could graze on a segment of land without destroying it. Later, the idea was expanded to more complex populations, like humans. For the human population, more complex variables such as sanitation and medical care are sometimes considered as part of the necessary establishment. As population density increases, birth rate often increases and death rate typically decreases. The difference between the birth rate and the death rate is the "natural increase". The carrying capacity could support a positive natural increase or could require a negative natural increase. Thus, the carrying capacity is the number of individuals an environment can support without significant negative impacts to the given organism and its environment. Below carrying capacity, populations typically increase, while above, they typically decrease. A factor that keeps population size at equilibrium is known as a regulating factor. Population size decreases above carrying capacity due to a range of factors depending on the species concerned, but can include insufficient space, food supply, or sunlight. The carrying capacity of an environment may vary for different species and may change over time due to a variety of factors including: food availability, water supply, environmental conditions and living space. The origins of the term "carrying capacity" are uncertain, with researchers variously stating that it was used "in the context of international shipping" or that it was first used during 19th-century laboratory experiments with micro-organisms. A recent review finds the first use of the term in an 1845 report by the US Secretary of State to the US Senate.
The double layers of cell membranes is made up of PHOSPHOLIPIDS.
The cell membrane, also called plasma membrane is made up of double layers of phospholipids. Phospholipid is a type of lipid, which is made up of two parts, an hydrophillic head and a hydrophobic tail. The hydrophillic head is made up of phosphate and glyerol while the hydrophobic tail is made up of fatty acids. The double layer of phospholipids serves as a barrier that allows only certain substances to enter into the cells.
The double layer of a cell membrane is made up of phospholipids. These molecules form a phospholipid bilayer, where their hydrophilic (water-attracting) heads face outward and their hydrophobic (water-repelling) tails face inward, maintaining the cell's structural integrity and controlling substance passage.
The type of molecule that makes up the double layer of a cell membrane is called a phospholipid. Phospholipids are a type of lipid molecule that is a primary component of all cell membranes. They are structured with a glycerol backbone, two fatty acid chains which are hydrophobic (water-repelling), and a phosphate group which is hydrophilic (water-attracting). In the cell membrane, these phospholipids align themselves into two parallel layers, known as a phospholipid bilayer, with the hydrophobic tails facing inward and the hydrophilic heads facing outward. This molecular arrangement allows the cell to maintain its structural integrity while also controlling the passage of substances in and out of the cell.

The chromosomal mutation is C. Nondisjunction .Therefore , C. Nondisjunction is correct .
There are a number of factors that can increase the risk of nondisjunction, including:
Age: The risk of nondisjunction increases with age, especially in women.
Genetic factors: People with certain genetic conditions are at increased risk of nondisjunction.
Environmental factors: Exposure to certain environmental toxins, such as radiation, can also increase the risk of nondisjunction.
There is no cure for nondisjunction, but there are a number of things that can be done to manage the symptoms and improve the quality of life of people with nondisjunction-related birth defects.
Here are some additional details about nondisjunction:
Nondisjunction can affect any chromosome, but it is most common on chromosomes 21, 13, and 18.
Nondisjunction is estimated to be the cause of 50-60% of all miscarriages.
Nondisjunction is also the cause of some stillbirths and birth defects.

Identification of mutation type, such as point mutation, silent mutation, insertion, deletion, transversion, or transition, depends on the specific changes in DNA or RNA sequences. For example, a change in a single base pair signifies a point mutation.
A thorough identification of the type of mutation seen on Chromosome 20 goes beyond merely looking at the question diagram. It depends on the specific alteration of the DNA or RNA sequences. Several types of mutations exist including point mutations, silent mutations, insertions, deletions, transversions and transitions, among others.
As an illustration, suppose the mutation involved a single base pair alteration, this would be a point mutation where one nucleotide is substituted with another. Transversions involve switching a purine with a pyrimidine or vice versa. If the mutation led to an addition or removal of a base pair, this would be termed an insertion or deletion respectively. Occasionally, a fraction of DNA from one chromosome may get transported to another chromosome or a different part of the same chromosome, a scenario known as translocation.

B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.
C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.
During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.
A simple diagram of Cori cycle (lactic acid cycle) is given below:
The correct answer is true.
C. They help maintain ecological balance by preventing desertification. The seed is protected by The Ovaries.
