The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.A fossil can form when

‘Plant and animals are interdependent on each other’, Why do they depend on each other. Write three points to justify your answer.

The process of photosynthesis adds oxygen to the atmosphere. Option C is correct for the given statement. In the atmosphere, nearly 21% oxygen is present.
What is the gas constituent of the atmosphere?In the atmosphere, different gases such as oxygen, nitrogen, carbon dioxide, and water vapour are present. These differ in composition, with oxygen accounting for 21%, nitrogen accounting for nearly 78%, and carbon dioxide accounting for less than 1%.
The oxygen is produced by the process of photosynthesis that is undertaken by green plants. The phytoplankton, algae in aquatic habitats, and plants of the terrestrial ecosystem do photosynthesis because of the presence of chloroplasts.
This oxygen is used by animals and plants for cellular respiration. Others are incorrect options because forest fires increase carbon dioxide in the atmosphere, animals take oxygen from the atmosphere, and rock weathering does not add oxygen.
As a result, option C is the correct answer because photosynthesis produces oxygen for the atmosphere.

B: move to the left with the same speed

there is one correct answer
Answers
If a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, the ball will continue with the same velocity.
What is a balanced force?A balanced force occurs when the opposing forces acting on an object is equal.
According to Newton first law of motion, a body will remain at rest until it is acted upon by an external force.
However, a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, this means that a balanced force is acting on the object, hence, will move at the same velocity.

Variola virus, the virus known to cause small pox, produces soluble TNF alpha receptors (meaning that these receptors are secreted by the virus). What advantage does the production of a TNFalpha receptor have for avoiding immune response?
i. TNF alpha represents a family of soluble cytokines. By producing soluble receptors that bind to this cytokines, the cytokine effector response is eliminated and only a limited immune response will occur
ii. TNF alpha receptors bind to cells of the immune system and prevent the release of cytokines.
iii. TNF alpha receptors block transcription within infected cells so that new virus particles cannot be made.
iv. TNF alpha receptors bind to cytotoxic T cells, preventinglysis of infected cells.
v. TNF alpha receptors allow an infected cell to become infected by more than one variola virus particle
Answers
Answer:
i. TNF alpha represents a family of soluble cytokines. By producing soluble receptors that bind to this cytokines, the cytokine effector response is eliminated and only a limited immune response will occur
Explanation:
Cytokines represent a broad category of small proteins which are secreted by specific cells of the immune system. These molecules (cytokines) indicate instructions and mediate communication between immune and non-immune cells. The Tumour Necrosis Factor-alpha (TNF-alpha) is a cytokine that exhibits pleiotropic effects on cells (e.g., cell proliferation, cell death, etc). Cytokine antagonists are molecules capable of inhibiting cytokine activity by interacting with their receptors, by altering their production, or by directly binding to cytokines and thereby preventing their functions. The variola virus is a poxvirus, which encodes viral TNF receptors (vTNFRs) capable of blocking the activity of proinflammatory cytokines and thus avoids an effective host immune response.
