Answer: Absorb water

Explanation: i took the quiz the other guy is wrong

Absorbing the water from soil is function of root and not a stem. Thus, option B is correct.

The structural part of plant, that supports leaves, flowers, and fruits is called as stem. Stems are frequently differentiated for storage, asexual reproduction, protection, or photosynthesis.

The stem is divided into nodes and internodes. Node consist of buds and leaves, that can grow into the branches. It also gives rise to adventitious roots. The function of internode is to distance one node from another.

Stem supports and uprights leaves, flowers and fruits. The stem keeps the leaves in the light and provides the plant with a place to hold the flowers and fruit. It transports fluid between xylem and phloem roots and shoots. Therefore, transportation of water and nutrients is the function of stem, and not absorption. Hence, option B is correct.

Answer:

Loss of the structural framework of the brain.

Explanation:

Damage to oligodendrocytes in the central nervous system leads to the loss of the structural framework of the brain. oligodendrocytes produce the insulating sheath of axons and we know that axons are the nerve fiber that conducts electrical impulses away from the neuron's cell body. Axons are the primary transmission lines of the nervous system that carries impulse throughout the body so if the oligodendrocytes are damaged then our brain did not work properly.

If oligodendrocytes are damaged, the myelin sheaths around axons can be destroyed. This can lead to a loss of the structural framework of the brain, as the axons will no longer be properly insulated. Hence option C is correct.

Oligodendrocytes are glial cells in the central nervous system (CNS) that are responsible for myelinating axons. Myelin is a fatty sheath that surrounds axons and helps to speed up the conduction of nerve impulses.

The loss of the structural framework of the brain can cause a variety of neurological problems, including:

Reduced speed of nerve impulses. As mentioned above, myelin sheaths help to speed up the conduction of nerve impulses. Without myelin sheaths, nerve impulses will travel more slowly, which can cause problems with coordination, movement, and sensation.

Increased risk of seizures. Seizures are caused by abnormal electrical activity in the brain. When the myelin sheaths around axons are damaged, it can increase the risk of seizures.

Cognitive impairment refers to a decline in thinking and memory skills. Damage to oligodendrocytes can lead to cognitive impairment, as the axons will no longer be able to function properly.

Therefore, option C) loss of the structural framework of the brain is correct.

Answer:

A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.

Explanation:

this is the example answer. do what you will w it

The passive and active freezing protections can be done by planting facing north hill and providing overhead irrigation respectively.

This is the process of guarding something against damage from an external force.

The passive and active freezing protections are effective as it minimizes the risk of freezes and frosts during spring blooms.

You will find the model of the cell cycle in the attached files

Answer:

A. Arrow 1 represents interphase, and Arrow 2 represents mitosis.

Explanation:

When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).

Interphase: Represented by arrow 1.

The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.

• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.

• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.

• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.

Once the whole interphase is completed, mitosis occurs.

Mitosis: Represented in the cycle by arrow 2.

Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the whole-cell first duplicates and then separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). During prophase, chromosomes condensate, and the nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.

A major impact of combustion on water quality is the potential for increased precipitation. Runoff can carry suspended soil particles, dissolved inorganic nutrients, and other materials into nearby rivers and lakes, degrading water quality and damaging fish habitat.

C. The mountain has wider range of environments.

Explanation:

Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.

There are various locations and climates on earth where grassland environments can be found. Depending on where in the world they are and the type of climate there, they may also be referred to as prairies, savannahs, steppes, or pampas.

Because there are few places for animals to hide from predators in grasslands, they have developed underground burrows or grown tall enough to look over thick grasses and shrubs.

Many grasslands have been used for farming because they are suitable for raising crops and providing food for cattle. Yet, this means that grassland animals can no longer reside there.

Therefore,  Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.
