You explain to the child's parents that the role of the mitochondria would be to produce the energy currency, ATP, for a cell.
So, the correct option is B.
The traditional function of the mitochondria is called oxidative phosphorylation, which produces ATP by using the energy generated through the oxidation of the food we ingest. The majority of biochemical and physiological functions, including growth, mobility, and equilibrium, all require ATP as their main energy source. The mitochondria in the cell use the oxygen already present to transform the chemical energy from the meal into energy that can be used by the host cell.
Within the mitochondria, a procedure known as oxidative phosphorylation takes place. For the purpose of making ATP, mitochondria oxidize their substrates, which generates heat. The cytosol and mitochondria may be up to 10 °C hotter, according to new theories.

What is the correct sequence of events for activation of a b cell by a t-dependent antigen?.
The correct sequence of events for activation of B-cells by T-dependent antigen is recognition of antigen, fragmentation, binding and secretion.
The process can be understood as firstly immunoglobulin receptors on the B cell recognize and bind with the antigen, secondly an antigen fragment in complex with MHC class 2 is displayed on the B cell's surface, thirdly the MHC-antigen complex binds a receptor on a TH cell and finally the TH cell secretes cytokines that activate the B cell. B-cells are the antibody producing cells that produce antigen specific immunoglobin molecule to fight against the pathogens such as bacteria or fungi. These B-cells are found in bone marrow of an individual. Lesser number of B-cells in the body makes it prone to infections as the immune system gets weak. T cells are the types of white blood cells primarily involved in directly killing of infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

Which species concept is primarily used to define extinct species known only from the fossil record?.
Phylogenetic species concept is primarily used to define extinct species known only from the fossil record.
What is Phylogenetic species?Although species serve a variety of special and essential functions in biology, none are more crucial than their involvement in phylogeny, naming, and biodiversity research. There is no way to divide species into smaller units where shared derived features may be accurately identified. A universally applicable species idea is necessary for biodiversity inventory, evaluation, and conservation. In formal Linnaean classification and zoological nomenclature, species are the fundamental units.
The Biological Species Concept pushed a basic taxonomic problem—what are species?—into a population genetics framework—why are there species?—and has long had only minimal support from most zoologists. Early attempts to develop a phylogenetic species concept concentrated on fixing issues with the biological species concept related to ancestral populations before applying phylogenetic reasoning to the actual species.

This practice will benefit the farmer in fixing the nitrogen in the soil
What is clover?
Clover is a member of the distinguished legume family. On the roots of legumes are bacteria that can convert atmospheric nitrogen into a form that plants can use. Plants utilize nitrogen in large quantities since it is a component of chlorophyll. The farmer enriches the soil with plenty of nitrogen and organic matter by planting clover and plow it beneath. A crop would be seeded after allowing the organic matter to decompose.
Advantages of clover in agriculture:
Clover is a Fixer of Nitrogen.
Clover is a legume crop that is a member of the bean and pea plant family. It helps the soil fix nitrogen. In other words, it works with helpful bacteria to convert nitrogen gas that is present in soil air pockets into stable organic molecules that feed nearby plants.Animals Love It
Because it is so nutrient-rich, clover provides farmers with a high-protein meal for their animals and enhances digestibility. Leaner meat and more nutrient-rich milk are produced as a result of reducing mineral deficiency, which can cause a number of illnesses and problems.Additionally, clover can be used as poultry feed for chickens, geese, and birds (and even humans - clover is edible and its colorful flowers can really make a salad pop).Positive insects and pollinators I adore it, too
Honey bees are drawn to the readily available nectar found within the small florets of white clover and crimson clover, which is why clover honey isn't simply a smart name. Clover, dandelions, and other "weeds" have been eliminated, and this has resulted in a sharp fall in bee populations, according to scientists.Hence clover practice is beneficial to farmers
