Answer:

Hair grows by forming new cells at the base of the root. These cells multiply to form a rod of tissue in the skin. The rods of cells move upward through the skin as new cells form beneath them. As they move up, they're cut off from their supply of nourishment and start to form a hard protein called keratin.

Explanation:

Skin cells are designed to be shed and replaced quickly, and they lack mitochondria (which helps to generate energy).

Cells are the foundational building blocks of all life. Many of cells make up the human body.

They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.

Hair grew back by establishing new cells at the root's base. These cells divide and multiply to form a tissue rod in the skin.

As new cells form beneath them in that case, the cell rods starts moving upward through the skin. As they progress, they are cut off from their food supply and begin to form keratin, a hard protein.

Thus, this way, it can be concluded that, hair cells are different from skin cells.

Answer:

lipids

Explanation:

lipids also can contain sulphur (C, H, O, N, S, P)

Answer:

(a) lungs

Explanation:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Answer:

B. The activity will speed up

Explanation:

As temperature increases, enzyme activity increases (until is passes the optimum temperature)

Answer:

Under normal ambient conditions water is less dense as a solid than as a liquid, so ice floats on water. Most materials are more dense as solids.

It's actually D on edge2020. Tundra has limited veg, the two types are alpine and artic, and temperatures can get below -20F. Tundra can support animal life, but it's just extremely harsh and unforgiving.

The statement that is not true about the tundra is the tundra biome doesn't support animal life. So, the correct option is D.

Tundra biome is found at high latitudes, where sunlight is low. The soil in this region is completely frozen and nutrients are limiting. The average temperature of this region is below -10°F. The vegetation consists of low shrubs and grasses.

As the nutrients are limited in the tundra biome, it has limited vegetation. There are two main categories of the tundra biome i.e. Arctic tundra and Alpine tundra. Animals such as the arctic hare, the arctic fox, the musk ox, the polar bear, etc. are present in the tundra habitat.

Therefore, the statement that is not true about the tundra is the tundra biome doesn't support animal life.

Answer:

Paramecium and amoeba live in fresh water. Their cytoplasm contains a greater concentration of solutes than their surroundings and so they absorb water by osmosis. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane.

Explanation:

Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.

Answer:

The fact that organisms live together forces them to interact in different ways. For example, an organism preys upon another for food. Or perhaps there is competition among organisms over resources such as food, water, and territory.

Answer:

20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

Answer:

The correct answer is:  E. Coli is a harmful bacteria that can be killed by high temperatures.

Explanation:

E.coli or Escherichia coli is a gram-negative bacteria that are normally harmless but there are many strains that cause harm to individuals including humans. These bacteria come in contact with organisms through contaminated food or water and cause diarrhea and other illnesses inside and outside of the intestine.

These bacteria can be killed by the high temperature as they are not able to live at a high temperature that is the reason high temperature is used to decontaminate the water or places that are at high risk of exposure to the bacteria.

Answer:

the correct answer is E. coli is a harmful bacteria that can be killed by high temperatures. Or C

Answer:

The discharge of effluent from wastewater treatment plants (WWTPs) has major detrimental effects on the health of aquatic ecosystems. WWTP outfall can deposit large amounts of organic matter and nutrients into receiving waterways. Increased nutrient loading can lead to eutrophication (20) and temporary oxygen deficits (35)

Answer:

uhh if its asexual reproduction then 4. isnt true. there are no variations since its just basically the cell splitting.

Explanation:

Answer:

Because some materials can come in and some materials must stay out

Explanation:

Cell membrane is a structure that covers or bounds the cytoplasmic layer of every living cell. It is made up of mostly lipids. According to this question, it is regarded as selectively permeable. This means that it selects what goes into the cell and what comes out.

The cell membrane is capable of this because of its amphipathic nature i.e contains both hydrophilic and hydrophobic regions. Because the cell membrane controls what goes into the cell and what comes out of the cell, it is referred to as selectively permeable as some materials can come in and some materials must stay out.

Answer:

Viruses must use their host’s cellular machinery in order to reproduce

Explanation:

The evidence that viruses use their host’s cellular machinery in order to reproduce put viruses in non living category. Thus option B is correct.

Viruses are microscopic infectious agents that contain genetic material, either DNA or RNA, and must invade a host in order to multiply.

Living things reproduce. Cells generally reproduce by replicating their DNA. Unlike cells, viruses do not have the tools to replicate their DNA.

But they have found other ways to create new viruses. This is done by introducing viral genetic material into the host cell.

Many scientists claim that although viruses can use other cells to reproduce, viruses are still not considered alive under this category. This is because the virus does not have the tools to replicate its genetic material on its own.

Therefore, scientists consider virus as non living because they do not have their own machinery to replicate their genetic material. Thus. option B is correct
