Answer: One part of the plants vascular system is its stem which contains vascular tissues, giving it the strength to stand up, while also conducting water a nutrients to and from the roots, to the leaves.

Explanation:

Answer:

vascular system, in plants, assemblage of conducting tissues and associated supportive fibres. Xylem tissue transports water and dissolved minerals to the leaves, and phloem tissue conducts food from the leaves to all parts of the plant.

Because they have a wide surface area to speed up absorption, root hair cells are designed to absorb water and mineral ions.

Plants are anchored by root hairs that emerge from the surface of the soil and take up water and minerals.

Vascular tissue in the heart of the root transports food produced in the leaves to the root, while transporting water and minerals away from it.

Its main purposes include anchoring the plant, absorbing water and dissolved minerals and transferring them to the stem, as well as storing reserve food.

Water and nutrients are mostly taken up by root hairs from the rhizosphere.

Therefore, root hair cell have large surface area that enable the cell to carry out its function.

Explanation:

Cholesterol refers to a group of chemical compounds. A sterol is a kind of lipid, and cholesterol is one of them. All animal cells produce cholesterol, which is an important structural component of cell membranes. It is a yellowish crystalline solid when chemically separated.

a sterol-type molecule present in most human tissues. Cholesterol and its derivatives are key components of cell membranes and precursors of other steroid chemicals, but a high proportion of low-density lipoprotein in the blood (which delivers cholesterol to the tissues) is linked to a higher risk of coronary heart disease.

Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol you require.

I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.

In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes.  So, I am agree with this statement.

Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.

Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.

Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.

In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

Potential energy is greatest at point D. Therefore, option C is correct.

Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.

The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.

Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Option D has the highest concentration of lactic acid in the student's muscle tissue.

We can arrive at this answer because:

As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.

It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.
