Why is there a need for a student to get acquainted to different laboratory apparatus?
A student needs to get acquainted with different laboratory apparatuses because then they can prevent any error, accident, or hazard from happening.
While working in the laboratory, a student needs to know which apparatus is required to perform what experiment/function. They need proper practice so as to remember the specific job of every instrument.
For example, a student should know that they need to use a cover slip properly so that they can prevent any bubbles from forming on their slide while looking at it under the microscope. If they do, they potentially reduce the chances of error in their calculations.

in coelomate animals, what type of tissue surrounds the digestive tube? What function does this type of tissue usually serve in other locations in the body?
The coelom is found between the intestinal canal and the body wall, lined with mesodermal epithelium. Coelom can absorb shock or provide a hydrostatic skeleton.
Coelomic fluid function of a hydrostatic skeleton, which helps for locomotion of soft-bodied animals and provide body a distinct shape. Contracting muscles can push against the coelomic fluid because of the fluid pressure.
In coelomate, the tissue that lines the inner side of the body cavity come from the same germ layer as the tissue lining from the outer side of the body cavity. Hence, The digestive tract of a coelomate functions as a coelom.

What are the steps for photosynthesis?
Photosynthesis is defined as the process by which plants use energy from sunlight in the manufacturing of food.
What are the steps of photosynthesis?The photosynthetic process in green plants occur in four distinct steps that includes the following:
Absorption of light: This is the first and important stage of photosynthesis that involves the absorption of light by the chlorophyll which is located at the chloroplast of.most green plants. This leads to the splitting of waters molecules to form oxygen.Electron transfer: As the electrons are transferred through the membrane, protons are pumped out of the membrane, resulting in the proton gradient across the membrane.Generation of Adenosine triphosphate (ATP): The movement of protons from the thylakoid lumen to the stroma leads to the generation of ATP.Carbon fixation: The ATP generated drive the process of reducing carbon into six-carbon sugar molecules.Learn more about photosynthesis here:

C. using fertile soil to grow
horticulture
D. water absorption from plants
Answer:
B.
Explanation:
Photosynthesis is basically plants using sunlight (or any light) to make 'food'.
Plants, algae, and cyanobacteria that contain chlorophyll engage in the most prevalent and important type of photosynthesis. These organisms absorb solar energy and transform it into chemical energy contained in the molecules of carbohydrates by using carbon dioxide and water. Thus, option B is correct.
What are the process involving in photosynthesis?The three episodes that occur during the photosynthesis cycle are: Light energy is absorbed by chlorophyll, which breaks down water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. The reduction of carbon dioxide leads to the formation of carbohydrates.
The photosynthetic cycle contains three stages, which are as follows: Light energy is absorbed by chlorophyll, which then divides water molecules into oxygen and hydrogen. Light energy is converted into chemical energy. Carbon dioxide is reduced, which results in the creation of carbohydrates.
Therefore, using light to make high-energy carbohydrates.

what is the net gain of energy when going from the bonds broken to forming new bonds in new proteins?
While a gram of protein has four calories, the same as a gram of carbohydrates, the body does not readily use protein as a fuel source. Around 5% of the daily energy needs are met by protein on an average day.
What is the involvement of protein in energy production?Because a large portion of the energy required to build complex organic food molecules like sugars, lipids, and proteins is physically stored inside the chemical bonds that keep them together, these molecules are abundant sources of energy for cells.
In some reactions, energy is absorbed because more energy is needed to break bonds than is created when new bonds are formed.
Therefore, When bonds are broken, energy is absorbed, and when bonds are formed, energy is evolved.

Erosion is the geological technique wherein earthen substances are worn away and transported with the aid of using herbal forces together with wind or water. A comparable technique, weathering, breaks down or dissolves rock, however does now no longer contain movement. Erosion is the alternative of deposition, the geological technique wherein earthen substances are deposited, or constructed up, on a landform. Most erosion is accomplished with the aid of using liquid water, wind, or ice (commonly with inside the shape of a glacier).

Which could cause a
change to the carrying
capacity of a species in an
ecosystem?
A. seasons changing
B. continuous rotation of resources
C. more predators
D. consistent rain falls
The carrying capacity of a species in an ecosystem is the continuous rotation of resources. Option B.
As abiotic or biotic factors change so does the carrying capacity. Natural disasters can destroy ecosystem resources. When resources are destroyed, ecosystems can no longer support large populations. This reduces the payload. Increased food production through improved agricultural practices control of many diseases with modern medicine, and the use of energy to render historically uninhabitable areas.
Earth's habitable is an example of something that can expand its carrying capacity. Altering ecosystems can increase the carrying capacity of some species, as other species are overwhelmed and populated while others are dramatically reduced due to hunting. Carrying capacity is the maximum number of individuals in a population that the environment can support.

describe another situation in which the cell cycle short to allow rapid cell division before returning to normal
Overexpression of growth factors or the absence of suppressor proteins can lead to rapid cell division.
How the cell cycle allows cell division before returning to normal?The study of the cell cycle focuses on the apparatus that regulates the timing and frequency of DNA duplication and cell division during the mitotic (M) phase, the cell divides its duplicate DNA and cytoplasm to make two new cells. M phase involves two distinct division-linked processes such as mitosis and cytokinesis. A cell cycle is a series of events that takes place in a cell as it fattens and divides. A cell spends most of its time in what is called interphase, and through this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and concluded its division.
So we can conclude that the division cycle of most cells comprises four processes such as cell growth and DNA replication.
