Answer:
A. nutrition
Explanation:
The most likely explanation for the remainder of the variation would be nutrition. Little is known about how exactly nutrition affects genetics and heritability, but it is known that it does. Scientists believe that traits that allow a species to feed more successfully have a drastically increased chance of appearing in offspring as it greatly contributes to their survival. When a trait does not allow the species to gain the proper nutrition, the species tends to develop other traits to accomplish this which then get passed on to offspring.
Answer:
A. Nutrition
C. Precipitation

Which statement about the relationship between interphase, the cell cycle, and mitosis is true?
A. The cell cycle and interphase make up mitosis.
B. Interphase and the cell cycle are parts of mitosis.
C. Mitosis and interphase are parts of the cell cycle.
D. Mitosis and the cell cycle are parts of interphase.
Answer: C.Mitosis and interphase are parts of the cell cycle.
Explanation:Interphase is actually the longest stage of the cell cycle. This is the point where the cell prepares itself for division. It is composed of 3 phases:
G1 phase - is when the cell starts to grow and copies its organelles.
S phase - it starts making copies of its DNA and makes a copy of its centrosome.
G2 phase - continues to grow and produces the proteins or enzymes that will be used in the process.
After the stage of interphase, the cell will enter its M phase or mitosis in the case of body cells. Mitosis is the process of cell division.
Answer:
c
Explanation:
mitosis and interphase are part of the cell cycle
Question 4 (1 point) If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water?
A. Less than 22 grams because some mass is lost in the reaction
B.More than 22 grams because the oxygen gains mass during the reaction
C.22 grams because mass cannot be created or destroyed
D. There is no way to tell from this information.
Answer:
C.22 grams because mass cannot be created or destroyed
Explanation:
Reaction equation:
2H₂ + O₂ → 2 H₂O
Mass of oxygen = 18g
Mass of hydrogen = 4g
The mass of water produced is 22g according to law of conservation of mass.
The law states that " in a chemical reaction, mass is always conserved"
The sum of the mass of product and reactants must always be the same.

what process has the effect of changing ploidy?
Answer:
Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. For many organisms, especially plants and fungi, changes in ploidy level between generations are major drivers of speciation
Explanation:
Hope this helps.. this is something I got from a website. I didn't got the paste and the copy from someone else..
;)
Meiosis and fertilization are cellular processes capable of changing the ploidy level.
The ploidy level refers to the number of sets of homologous chromosomes in a given cell type.Meiosis is a type of cell division that is capable of reducing the number of chromosomes in the parent cell and thus produces four (4) gametes or germ cells.These gametes contain half the normal (i.e., somatic) number of chromosomes. During fertilization, two gametes combine to re-establish the ploidy level, i.e., the normal chromosome number in somatic cells.Thus, fertilization can restore the ploidy level of the parents.In conclusion, meiosis and fertilization are cellular processes capable of changing the ploidy level.

Disease outbreak - decrease - Because the disease will kill a lot of them and can potentially cause birth rates to go down
b. Name one advantage and one disadvantage of replacing wild forestland with
cropland.
Answer:
Advantage: Having the space and land to make an economy and to grow crops
Disadvantage: Destroying animal, and wildlife habitat and reducing O2 productions from trees
Explanation:
Why?
Deforestation can eliminate many living organisms and take down trees, which produce oxygen. On the plus side, the land allows for humanity to settle in, farm and start an economy.
One advantage is having the space and land to make an economy and to grow crops. One disadvantage: Destroying animal, and wildlife habitats and reducing O2 production from trees.
What is deforestation?
Many living things can be wiped out by deforestation, which also removes trees that produce oxygen. On the bright side, the land enables human settlement, agriculture, and the emergence of an economy.
The consequences of deforestation are increases in greenhouse gas emissions, which contribute to climate change, desertification, soil erosion, fewer crops, flooding, and a myriad of issues for indigenous people.
Therefore, having the room and acreage to build a business and raise crops is one benefit. One drawback is the destruction of wildlife and animal habitats, which lowers tree O2 output.

which description properly describes a step involved in cellular respiration? (4 points)
Glucose is created, then the energy gained is transferred to the energy molecule.
Carbon dioxide is combined with oxygen to make glucose.
Water is divided into carbon dioxide and glucose.
Oxygen is combined with the carbon atoms left from the glucose molecule.
Answer:
Oxygen is combined with the carbon atoms left from the glucose molecule.Explanation:
Plants are producers that make polysaccharides through the process of photosynthesis. These polysaccharides, are used to store chemical energy stably in their covalent bonds.
Mitochondria break down sugars in cellular respiration. Aerobic respiration for instance, breaks down glucose in the presence of oxygen, which produces carbon dioxide and water, while transferring energy to the molecule ADP, to produce ATP (adenosine triphosphate).
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Oxygen is the final electron acceptor, it combines with the leftover carbons in respiration resulting in the waste product [tex]CO_{2} \\[/tex].

Why are bacteria a necessary part of the nitrogen cycle?
Other living things cannot use atmospheric nitrogen.
Other living things cannot use the nitrogen in plants.
Bacteria are the main nitrogen reservoir.
Bacteria are the main nitrogen transpirators.
Answer: The answer is... (A) Other living things cannot use atmospheric nitrogen
Explanation:
Other living things cannot use the nitrogen in plants except bacteria which has the ability to use and convert nitrogen.
Role of bacteria in Nitrogen cycle
Atmospheric Nitrogen gas can't use by the plants directly but the bacteria are able to use the atmospheric nitrogen and convert it in available form to the plants.
The decomposers, soil bacteria and fungi break down proteins in dead organisms and animal wastes, releasing ammonium ions which can be converted to other nitrogen compounds which make the bacteria an important part of nitrogen cycle.
In conclusion, bacteria is the only organism which can use nitrogen.
