Why are enzymes important for chemical
reactions?
Answer:
Enzymes greatly increase the reaction rate, or catalyze them.
Explanation:
Without them, many of us would not be alive, because the reactions wouldn't be fast enough!
what would you make if you added CO2, water and energy
Answer:
You can react it with water to produce energy-rich hydrogen gas, or with hydrogen to produce useful chemicals, such as hydrocarbons or alcohols. If there were a sustainable, cost-efficient route to transform CO2 to CO, it would benefit society greatly.
Explanation:
Explain how the structure of a plant allows it to obtain and keep water.
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.
Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?
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).
Which of the following best explains what happens to the water that is expelled by photosynthesis?

Water is attracted to the sides of a glass cylinder is an example of cohesion.
What do you mean by 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.

What type of succession starts with some soil but then goes through the 10p
steps of succession?
A. Primary Succession
B. Secondary Succession
C. Climax Community
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]

Consider the evidence that explains how physical separation of two populations of a species can cause speciation. What effect does physical separation have on organisms that might result in speciation?
Answer:
Interruption in the genetic flow between separated groupsThe emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations. Genetic divergence by natural selection and reproductive isolation Prezigotic isolation mechanismsExplanation:
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:
The emergence of the barrier. Interruption in the genetic interchangeThe occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation. Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears. Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.the name of the layer in witch earths weather occurs

Be able to explain how segmentation and exoskeletons gave some animals an adaptive advantage over those that were not segmented and did not have exoskeletons.
Answer:
Arthropods have partially alleviated this problem by having the exoskeleton form as individual plates on each body segment or individual cylinders on each segment of the appendages. The plates are called sclerites, and they are connected by flexible tissue to allow the animal to bend during movement.Early land arthropods evolved adaptations such as book lungs or trachea to breathe air. The exoskeleton was another important adaptation. It prevents an animal from drying out. It also provides support in the absence of buoyant water.

Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow and divide, or by dying. In 2010 a group of scientists reported that a certain kind of immune reaction can cause DNA damage that leads to a fourth response. DNA damage can turn off genes involved in cell-signaling pathways. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of- a. tumors c. hemophilia b. allergies d. cardiovascular disease
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.
What is the most common cause of tumor?
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:
Benign: These tumors do not have any cancer-causing properties. They do not penetrate the tissue that is close by and they do not spread to other areas of the body.Tumors that are premalignant have cells that are not currently cancerous but have the capability of developing into cancerous cells in the future.Malignant: Malignant tumors are malignant.Learn more about tumors, here:

(I'm in 5th grade btw, and I have a big test coming up so this could really help)
Answer:
A.....
Explanation:
,.............
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.
Why do plants that live on the forest floor have big leaves?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.
