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.
Answer: c. connective
Explanation:
Connective tissue is the abundantly present tissue in the human or animal body. It is widely distributed and exists in varied type in the human or animal body. It includes the fat, bone, bone marrow, blood, cartilage, fibrous tissues. The function of the connective tissue is to provide the support and protection to the body. All connective tissues consists of fibers, cells and ground substances. The cells of the connective tissues include the macrophages, adipocytes, leucocytes, mast cells and fibroblasts.
The adipocytes are the cells which deposit fat in them. These cells are responsible for the majority of the weight in the body.
Answer:
9/16
Explanation:
This is a typical dihybrid cross involving two genes; one coding for anridia (form of blindness) and the other for Migraine headache, both in humans. The allele for possessing anridia (A) is dominant over the allele for not possessing it (a) in the first gene, while the allele for having Migraine headache (M) is dominant over the allele for not having it (m) in the second gene.
A cross between a man that is heterozygous for both genes (AaMm) and a woman also heterozygous for the two genes (AaMm), this means that both parents are dominant for the two traits i.e. they both possess anridia and migraine headache.
Both parent cells will undergo meiosis to produce four possible combination of gametes in which the alleles are independent of one another in the gametes, according to Mendel's law of independent assortment. The gametes are: AM, Am, aM, am
These gametes are crossed using a punnet square (see attached image) to produce 16 possible offsprings in a phenotypic ratio of 9:3:3:1.
9- Offsprings with both anridia and migraine
3- Offsprings with only anridia but without migraine
3- Offsprings with only migraine but without anridia
1- Offsprings without both anridia and migraine
According to the question, the chance of an offspring expressing both traits i.e. having both anridia and migraine headache is 9/16
b. thylakoid
c. grana
d. chlorophyll
The correct answer is Chlorophyll.
Chlorophyll is a pigment present in the plant that directly absorbs light from the sun rays. There are two types of chlorophyll called as chlorophyll a and chlorophyll b. They both absorb light. The maximum absorbed spectra is red and minimum absorbed spectra is blue. The green colored spectra is not absorbed by the plants making the plants appear green in color.
B. It is an energy source from the lungs.
C. It is waste produced by the cells in her body.
D. It is an energy source produced by the cells in her body.
