what is the utility of tissue in multicellular organisms​

Answers

Answer:

A tissue is classified as a cluster of cells that work together to perform a particular task and are structurally similar. In multicellular species, the use of tissues provides structural and mechanical strength and enables division of labour. For example, nerve cells from the nervous tissue help in the transmission of messages.

Multicellular organisms

Multicellular organisms are composed of more than one cell, with groups of cells differentiating to specialized functions. For example, cells differentiate early in development in humans to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. The cells of multicellular organisms may also look different according to the organelles needed inside of the cell.

They possess distinct organs and organ systems.

Their cells exhibit division of labour.

Their size increases with the number of cells in an organism.

Answer:

1.To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.

Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.Now prepare fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.After adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.Sprinkle water on a regular basis to maintain the moisture content of the compost.Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.

Infer why doctors recommend people, especially elderly and those with weak immune systems, get the flu vaccine every year.
(1 point)
O They should get the flu vaccine because viruses mutate.
O They should get the flu vaccine because viruses do not mutate.
They should get the flu vaccine because their bodies already have a resistance.
O They should get the flu vaccine because their bodies do not build up resistance.

Answers

Doctors recommend people with weak immune systems to get the flu vaccine every year because viruses mutate and their bodies already have a resistance.

Flu is common viral infection caused by a virus and attacks the lungs, nose and throat.

Vaccine for flu infections helps the immune to recognize and attack antigens from the flu virus.

Virus are known to mutate. Because of this, a weak immune system might not recognize the new mode of the virus which multiplies and cause damage to the system.

Therefore, old people and those with weak immune system are always advised to get the vaccine every year because whenever new variant are discovered, vaccine are improved and help the weak immune to recognized and attack any variant of the flu virus.

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell.

Answers

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

The ribosome represents the actual site of protein synthesis.The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

Answers

Active and passive transport are cellular processes that involve the transport of substances inside and outside the cells.

Active and passive transport help the cell to regulate the uptake and removal of materials (Option D is correct).

Passive transport is a type of transport that does not involve an energy input to transport substances in favor of a concentration gradient.

There are four main classes of passive transport:filtrationosmosissimple diffusionfacilitated diffusion
