Answer:

a) genetics and heredity: Genetics can be described as the study of genome or DNA of an organism. Heredity refers to the traits which are passed on from the parents to the offsprings. Not all of the genome of an individual is similar to the parents. Hence, genetics refers to the genome of an individual and heredity refers to the traits which pass from the parents to the child.

b) Dominant and recessive trait: A dominant trait is caused due to a dominant allele. A dominant allele is the allele which can mask the effect of the other recessive allele. Hence, a person can be homozygous or heterozygous for the dominant trait. A recessive trait arises due to the recessive allele. A recessive allele is the allele which gets masked by the dominant allele.

Pure and hybrid: A pure offsprings contains the same genetic character for a trait. It is a homozygous offspring. A hybrind offspring contains different alleles or genetic characters and is heterozygous.

Andreas93 [3]

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

State three examples of human activities that could endanger botana curus
statuscvo [17]

Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.

This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.

The human activities that could have endangered botana curus is:

Pollution: It lead to slow down the rate of growth of the plant.

Overexploitation: The over use of plant for its medicinal purpose.

Habitat: The natural habitat of the plant has been changed due to various human activities.

Answer:

Primitive Earth where life emerged was subjected to extreme conditions  

Explanation:

The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.

garik1379 [7]

Answer:

c. When a rose bush cell divides, it copies its parts then divides into two cells <em><u>and</u></em>

d. The bacterium was formed when another bacterium divided

Explanation:

C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).

D is correct because bacterium are <u>unicellular</u> organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of  many cells.
