Explanation:
If the plant can use energy from the sun to make ATP, why does it go through the trouble of using the ATP to make glucose?
Plants go through the trouble of using the ATP to make glucose because it provides it with nourishment and is used in the production of cellulose.
What is Glucose?This is referred as a simple sugar and a monosaccharide. it has a sweet taste and is readily absorbed in cells to provide energy.
Plants make ATP in a limited manner and the production of Glucose from it ensures the cells are adequately nourished and the production of cellulose is maximized.

After which event will ecological succession most likely happen? answer choices. a forest fire. a thunderstorm. a high tide. a lunar eclipse.
Ecological succession is most likely to happen after a forest fire. Option A is the correct answer.
Forest fires can cause significant disturbances to an ecosystem, clearing out vegetation and organic matter. This creates a blank canvas for new plant growth and colonization by other organisms. The absence of competition and the availability of resources in the post-fire environment provide opportunities for pioneer species to establish and initiate ecological succession.
These pioneer species gradually pave the way for the establishment of more complex and diverse communities over time, leading to ecological succession. Therefore, a forest fire is an event that often triggers the process of ecological succession.

Do you think the amount of foam in the glasses will differ? write down your prediction.
Answer:
The formation of foam is a process when the small bubbles of the gas get trapped inside a solid or a liquid a form is made and gets made by the tapping of millions of small bubbles and can be seen in marshmallows. The process of foam formation is thus through a dispersed medium and in general gas is present.
The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.

The anti-Mycobacterium tuberculosis compounds isolated from sea sponges by the research team in this case are made by microbes living in the sponges. Group startsTrue or False
The anti-Mycobacterium tuberculosis compounds isolated from sea sponges by the research team in this case are made by microbes living in the sponges. False
The compounds isolated from sea sponges and found to have anti-Mycobacterium tuberculosis activity are likely produced by the sponges themselves as a defense mechanism against pathogens. While some marine organisms have been found to harbor microorganisms that produce bioactive compounds, there is no indication in this case that the compounds were made by microbes living within the sponges.
The research team likely isolated and identified the compounds from the sponges through a process of extraction, purification, and chemical analysis, rather than through analysis of microbial populations within the sponges.

a. located in the space outside the nucleus.
b. spread evenly throughout an atom. c. concentrated at multiple sites in an atom.
d. concentrated in the center of an atom.
The correct option is D.
concentrated in the center of an atom.
Explanation:
In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

Imagine that you live on a farm and grow all your own food. In four to eight sentences, trace the flow of carbohydrate macromolecules through your farm. State how the macromolecules are produced, how they are passed along, and what they are eventually used for. In your answer, give specific examples of macromolecules and processes
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie.
What is a carbohydrate?The carbohydrate which is a macro-molecule is produced by the producer such as trees and shrubs etc. in the process of photosynthesis. These carbohydrates transfer to the primary consumer such as monkey who eat these plants. When the secondary consumer such as jaguar eat these primary consumer, this carbohydrate again transfer from one organism to another organism.
How is energy stored?This carbohydrate is a source of energy which is broken down in the stomach into glucose and this glucose is absorbed by the cells and releases energy by mitochondria in the form of ATP. This energy is used in various activities such as walking, running and breathing etc. Carbohydrate, proteins and fats are the examples of macro-molecules.

During photosynthesis, carbon dioxide and (oxygen / sodium chloride / water / methane) are converted through a series of reactions into two products: high-energy (proteins / hydrocarbons / sugars / sunlight) and (carbon dioxide / carbon monoxide / hydrogen/ oxygen) gas.
Answer:
water, sugars, oxygen
Explanation:
Water, carbohydrates, and oxygen Green plants and some other organisms use sunlight to create food from carbon dioxide and water. The green pigment chlorophyll is most commonly used in photosynthesis in plants, which produces oxygen as a byproduct.
What steps comprise photosynthesis?The capture of light. As the first stage of photosynthesis, chlorophylls linked to proteins in chloroplast thylakoids absorb light.During the photosynthesis cycle, three episodes occur: Chlorophyll absorbs light energy and breaks down water molecules into oxygen and hydrogen. Chemical energy is created by converting light energy. Carbohydrates are formed as a result of carbon dioxide reduction.Transfer of Atoms.

(d) All of these need outer and middle ears.
The ear is an essential organ for hearing in most vertebrates. The outer ear collects sound waves and directs them into the ear canal, while the middle ear contains the eardrum and three small bones (ossicles) that transmit sound vibrations to the inner ear.
These structures are essential for the process of hearing in most vertebrates, including dogs, and cats. Fish does not need an outer or middle ear to hear effectively. They have a unique sensory system called the lateral line, which allows them to detect vibrations and changes in water pressure, allowing them to hear sounds and locate prey in their aquatic environment.

A geneticist wants to determine what mutation in a DNA molecule changed the structure of a specific protein. What would the scientist need to know before planning the investigation?
The normal sequence of bases that code for the protein
Whether the mutation was a substitution, insertion, or deletion
The total number of bases in the DNA molecule
How many thymine bases are in the DNA molecule
A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.
What is mutation?A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.
By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.
Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.

Answer:
The correct answer is - gain of function, and dominant.
Explanation:
A mutation in which the gene that altered carries out the production of the product that has a new pattern of gene expression or a new molecular function.
Function mutations are always gain by almost always Dominant or in some rare cases semi-dominant so, the mutation in a coat color gene of a mouse alters an enzyme such that it produces a red pigment instead of the wild type, which is tan. This is a gain of function mutation, which is most likely dominant.
