The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.

A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.

The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.

The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.

The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.

Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.

The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.

Therefore, the correct option is A.

Explanation:

because it is beneficial in both plant an water

Answer:

(B) No this would not be a symbiotic relationship.

Explanation:

this is because symbiotic relationship is where the two organisms have a mutual relationship where they depend on each other. The plants depend on water for their growth while the water does not depend on anything from the plants.

An example of a symbiotic relationship is between rhizobium bacteria and leguminous plants.The rhizobium bacteria gets shelter and food from the leguminous plants while the leguminous plants use the bacteria to convert nitrogen in the air to nitrates through a process called nitrogen fixation.

Answer:

The addition of a water molecule breaks a covalent bond between sugar monomers

Explanation:

The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.

Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.

The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.

connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body

epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Explanation:

Answer

Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.

Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Answer:

it helps regulate them and keep them level going through the state of transpiration

Explanation:

to prevent too much water lost a plant will close it's stoma to store that water, this process is called transpriation. if the stoma is open it will dry out the plant.

so a plant losing water in reaction they will close their stoma which is homeostasis, homeostasis is balance. so for example u go through homeostasis when it's hot outside it results in u sweating, why? cause your body is trying to cool down and regulate it's self.

Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.

Answer:

im pretty sure its E

Explanation:

The sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only, as radiation can be classified into two main types: ionizing radiation and non-ionizing radiation.

Medical X-rays are a type of ionizing radiation used for medical imaging. Although the amount of radiation exposure from a single X-ray is usually very small, frequent exposure to X-rays can increase the risk of cancer. The use of X-rays in medical imaging is carefully monitored to ensure that the benefits outweigh the risks. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, which can cause damage to living tissue and increase the risk of cancer. Medical X-rays and the burning of fossil fuels are sources of ionizing radiation that can produce low-level radiation.

Hence, the sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only.
