Answer:

Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.

Explanation:

The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.

Answer:

She should consult a dermatologist immediately.

Explanation:

When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).

Answer:

mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way dna codes the genetic information (genotype). when mutations occur they can cause termination (death) of an organism or they can be partially lethal.

good luck :)

D. A mutualism relationship, because the fungus and algae both benefit from the relationship

Explanation:

The reason it's D is because a mutualism relationship means that both organisisms benefit from the relationship. Explained in the question, the fungus obtains the resources that the algae uses to make them both food.

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]

Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.

The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]

It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.

Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]

Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.

Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: [tex]6CO_2+6H_2O=C_6H_1_2O_6+6O_2[/tex].

Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.

A chromosone is a long DNA molecule

It can lead to the development of A. Tumors

Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of (A) tumors.

When cells reach their end of life cycle or get damaged, they pass away and are replaced by new ones. This normally well-regulated process can, on occasion, become disorganized, allowing aberrant or damaged cells to proliferate and reproduce when they should not. These cells have the potential to develop tumors, which are mass accumulations of tissue.

There are primarily three different kinds of tumors:

Water is attracted to the sides of a glass cylinder is an example of cohesion.

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion.

Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Explanation:

Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.

The process of allopatric speciation involves different steps that affect organisms:

If a forest has many large trees with lots of leaves, the likely thing that could be found on the ground is very few small plants, because the trees block all the sunlight. Thus, the correct option for this question is A.

The forest floor gets almost no light at all. Leaves in these environments have adapted to low light and lots of water. Large leaves are arranged horizontally to absorb the most light possible. This is because these plants have plenty of access to water, and they can keep large leaves alive.

The plants that live on the floor of the forest have bigger leaves so that they can absorb the little light that comes through rather the plants that live in hot sunny conditions don't need to store as much sunlight. Cacti are plants that live in extremely dry environments.

Therefore, if a forest has many large trees with lots of leaves, very few small plants would be found on the ground because all the trees block the sunlight. Thus, the correct option for this question is A.

Answer:

Stem tuber ---- Potato

Conditioned reflex ---- Pavlov's experiment

Blood circulation ---- William harvey

Pancreas ---- Insulin

Autotrophs ------ Blue green algae

Active transport ---- Minerals

Note: Chlorosis has no matching item in the list. Explanation is given below.

Explanation:

Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.

Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's  performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.

William Harvey discovered the circulation of blood and the function of the heart .

The islets of Langerhans found in the Pancreas secretes the hormone, insulin.

Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.

Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.

Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.
