People who do not use insect repellents or wear protective clothing when entering endemic areas are at an increased risk of T. brucei infection.

Trypanosoma brucei (T. brucei), which is only found in sub-Saharan Africa, infects people when a tsetse fly bites them. When the tsetse fly bites, it ingests the parasite, which it then transmits to another host through its saliva. The parasite is found in the blood of infected humans and animals.

Only Sub-Saharan Africa, where tsetse flies are found, is affected by the virus.  Without taking precautions, such as applying insect repellents, travelers to endemic regions run the danger of being bitten by tsetse flies and contracting T. brucei.

Keeping a large number of livestock on a small amount of land results in soil erosion, option D is correct.

Keeping a large number of livestock on a small amount of land can lead to overgrazing, which in turn leads to soil erosion. Overgrazing occurs when animals consume more forage than can be naturally replenished, leaving the soil bare and exposed to the elements.

As a result, the topsoil is washed away by rainfall, and the land becomes prone to flooding and landslides. Soil erosion not only affects the productivity of the land but also causes environmental degradation. It results in the loss of essential nutrients from the soil, increased water pollution, and decreased biodiversity, option D is correct.

Answer:

Explanation:

Meristems are regions in plants where active cell division occurs, resulting in the growth of new plant tissue.

Apical meristems are located at the tips of roots and shoots and are responsible for primary growth in plants.

Apical meristems are important because they are responsible for the growth of new tissues that give rise to leaves, stems, and roots, which are essential for plant growth and development.

The growth of new plant tissue is caused by the continuous activity of apical meristems, which divide and differentiate to form new cells and tissues.

The shoot apical meristem produces structures such as leaves, stems, and flowers as its cells divide by mitosis.

Tropism is the growth response of a plant to a particular environmental stimulus.

Two types of tropisms are phototropism, which is the growth response of plants to light, and gravitropism, which is the growth response of plants to gravity. In phototropism, plants respond to the direction and intensity of light by growing towards it, while in gravitropism, plants respond to the direction of gravity by growing either towards or away from it.

The main group of plant hormones are auxins, gibberellins, cytokinins, abscisic acid, and ethylene.

The main functions of plant hormones include regulating growth and development, controlling tropisms, responding to environmental stimuli, and coordinating plant responses to stress.

Auxin influences gene expression by binding to specific receptors in the nucleus of cells, which leads to changes in gene expression that regulate cell growth and differentiation.

Micropropagation is a technique used to produce large numbers of plants from a small amount of tissue.

Micropropagation is done by culturing plant tissue in vitro, under sterile conditions, and providing it with the necessary nutrients and plant hormones to stimulate growth and development.

Micropropagation is done for several reasons, including the production of disease-free plants, the preservation of rare or endangered species, and the rapid propagation of genetically identical plants for commercial purposes.

Darwin's theory of evolution by natural selection was more powerful and useful than the proposals of other scientists because it provided a comprehensive and well-supported explanation for how and why species change over time.

Before Darwin, scientists such as Lamarck and Lyell had proposed that living things could change over time, but they lacked a comprehensive mechanism to explain how and why these changes occurred. Darwin's theory of evolution by natural selection not only provided a mechanism for how species change over time, but it also explained why certain traits become more prevalent in a population over time.

Darwin's theory was supported by a vast amount of empirical evidence, including observations of artificial selection, biogeography, and the fossil record. Additionally, his theory provided a unifying framework for understanding the diversity of life on Earth, and it has been refined and expanded upon by subsequent generations of scientists.

Two tropisms in plants are phototropism and hydrotropism. Phototropism refers to a plant’s response to light while hydrotropism is the plant’s response to water.

Auxins and Cytokinins are two groups of hormones produced by plants. Auxins help to promote stem growth while cytokinins help in cell division.

The main function of the plant hormones is to promote growth and development activities such as cell division seed formation flowering, dormancy, enlargement, etc. in the plant.

Auxins control the process of development by altering the expression of many genes. Auxin promotes cell elongation in shoots while it inhibits cell elongation in the roots.

Micropropagation is the process of artificially growing plants in the laboratory through cell culture or tissue culture techniques by providing the necessary nutrients in the medium.

In the process of micropropagation small pieces of plant tissues are grown in the nutrient medium by providing the necessary conditions required for growth.

Micropropagation is done to obtain plants with desired traits. It is also helpful to produce a large number of plants in a shorter time span and to produce healthier plants with greater disease resistance.

External factors such as temperature, day length, and stress can affect gene expression and flowering.

The phytochromes help to detect the presence of light in plants and also regulate seed germination and flowering in plants.

The process of transfer of pollen from the anther to the stigma of the flower is termed pollination.

The fusion of a male gamete and a female gamete to produce a diploid zygote is called fertilization.

It is a mechanism by which the seeds are transferred or spread by different means or factors for the germination of new plants.

Off-season flowering can be induced by interrupting the day with a period of darkness.

The process of sprouting seeds or spores after dormancy is termed germination.

The factors which are necessary for the germination of seeds are oxygen, water, light, and proper temperature.

Gibberellins play an important role in seed germination. GA promotes seed germination by increasing the growth potential of the embryo and inducing hydrolytic enzymes.

Offspring inherit traits in both asexual and sexual reproduction; however, the diversity of inherited traits is more prevalent in offspring with two parents.

When speaking of asexual reproduction, a single parent produces an offspring through means such as parthenogenesis or fragmentation, where genetic information deriving solely from the same parent generates without any recombination of genetic materials from individual donors.

In contrast to that, two parents producing offspring by sexual reproduction each offer half of their own genetic material contributing jointly to the formation of varied and distinct genetic traits during fertilization which arises from meiosis cell division. These hybrid traits comprise characteristics drawn from both individuals' inheritance resulting in manifold outcomes.
