Answer:
2
Explanation:
Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates.

If the consumption of carbohydrates lowers, then ATP production will likely remain the same as the cell can use other compounds that feed into the glycolysis and citric acid cycles. Option 4 is the correct answer.
How is ATP produced from food?The dietary carbohydrates, protein, and fat are broken down to produce energy. The body generally uses glucose, as it is the simplest source of energy. Less energy is used to break down the glucose for energy.
From lipids and proteins, energy can be derived too. Lipids such as saturated lipids need more energy to break down the covalent bond. To generate energy from the lipid, the body must expend more energy. A lipid molecule generally produces 9 kcal of energy, while a carbohydrate molecule produces 6 kcal.
If the carbohydrate level decreases, the body will use the lipids to produce ATP. ATP production will not stop in the absence of carbohydrate until the body has lipid as a reserve material.
Hence, Option 4 is the correct answer as ATP will produce from other source.

Question 4: Suppose there were changes in the habitat that caused this actual value. What might a
combination of those changes be?
Please help if you’ve done this for biology on e2020
Answer:
The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate.
Explanation:
A combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springs What is a habitat?A habitat refers to a combination of resources and geographical area that defines where the particular species of a living organism such as a rabbit, generally lives and thrives.

The cellular mechanism that determines the independent assortment of maternal and paternal chromosomes is: Please choose the correct answer from the following choices, and then select the submit answer button. determined by their dominant or recessive inheritance pattern. separation of sister chromatids at anaphase II of meiosis. separation of sister chromatids at anaphase I of meiosis. separation of homologous pairs at anaphase II of meiosis. separation of homologous pairs at anaphase I of meiosis.
Answer:
separation of homologous pairs at anaphase I of meiosis.
Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.
When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
what happens when an atom has lost an electron comes in contact with an atom that has gained an electron?
Answer: When an atom that has lost an electron comes in contact with an atom that has gained an electron, usually the the two atoms would attract each other and form a compound. This compound would be ionic since it is governed by ionic bonding.
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, ________.
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.

The following claims correctly describes a kingdom of Domain Eukarya is Kingdom fungi includes organisms that get energy by decomposing materials in their environment.
What are the main features of the Fungi kingdom?Fungi are heterotrophic and eukaryotic organisms that can be unicellular or multicellular. The vast majority of species are filamentous, and these filaments are called hyphae. Some fungi are formed by several densely packed hyphae, which form the so-called mycelium.
The Fungi Kingdom is represented by unicellular or multicellular eukaryotic organisms, being found in the most diverse types of environments. Fungi include mushrooms, molds, wood ears, lichens, among other organisms.
