Apoptosis is used by cytotoxic T lymphocytes to kill infected cells.
Antibody-producing plasma cell.
Releases cytokines and interleukins to activate other cells.
T and B cells undergo differentiation into effector cells after activation, which carry out vital effector tasks such generating cytotoxic antipathogen chemicals and antibodies, respectively. Innate, adaptive, & passive immunity are the three kinds that exist in humans. innate defense: Innate (or natural) resistance is a form of all-encompassing defense that is present from birth. The skin, for instance, serves as a barrier to prevent pathogens from entering the body. Lymphocytes (T cells, B cells, & NK cells), neutrophils, and monocytes/macrophages are the immune system's most prevalent cell types. White blood cells come in a variety of forms. T cells can eliminate malignant or contaminated cells. Additionally, they control the immune reaction by assisting B cells in eradicating foreign infections. Antibodies are made by B cells.

Write 5-6 sentences that explains roles of Heredity and probability.
Answer:
Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.

Hello there, kawissaehsshen!!!
The answer here would be A. The organism is a singular thing, so it should be first. The population comes next - it is all the same type of organism living in one ecosystem. Next is community - this is all the living organisms in the area. Lastly, there is the ecosystem - the organisms, their habitats, and everything else.

Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

What happens in the light reaction of photosynthesis?
What happens in the dark reaction of photosynthesis?
What five factors affect photosynthesis and its rate? How?
Answer:
Ans - 1 Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
Ans-2 The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
Ans-3 The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.

Answer:
The answer is "using wind energy to generate electricity".
Explanation:
The Wind turbines may not emit water or sulfur compounds (with rare exceptions) and require no water as a coolant. The cost of power produced from energy sources may also be reduced by windmills, which will result in lower overall air quality and hosing pollution, that's why Utilizing wind energy for energy production decreases human greenhouse gas sources.
