Which of the following variables have been shown to affect anaerobic respiration?
[Select ALL that apply]
solubility
pH
lactic acid concentration
availability of nutrients
oxygen levels
Answer:
When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown—and thus energy production—to continue.

Which of the following animals will provide the best soil aeration?
1.wolf
2.earthworm
3.fox
4.grasshopper
Answer:
The correct answer is - option 2. earthworm.
Explanation:
Soil aeration is one of the major factors that help in the productivity of the soil, it is the phenomenon that exchanges the gases between the atmosphere and soil. Microbes and plants leads to change in the oxygen and carbon dioxide in the soil. Volume of the macropores, oxygen, CO2, redox potential helps in the determining the soil aeration.
Earthworms are the natural way of the help in the status of the soil aeration as they help in the increasing the volume of the macropores in the soil asnd help. They help in increasing soil porosity which increases the air and gases in the soil.
How do enzymes help join two substrate molecules together to form a product?
Answer:
Enzymes bind with chemical reactants called substrates. ... In others, two substrates may come together to create one larger molecule. Two reactants might also enter a reaction, both become modified, and leave the reaction as two products. The enzyme's active site binds to the substrate.

Design an experiment to determine whether lactase persistence in the different global hot spots was caused by one or several mutations
Answer:
Collect DNA from individuals who are lactase persistent and are from the global hot spot populations. Then look for genetic differences correlated with lactase persistence; the first place to look would be in and around the lactase gene. Compare the genetic differences to see if they are the same or different.

Answer:
Explanation:
Nor do viruses have cells: they're very small, much smaller than the cells of living things,Bacteria are also much bigger than viruses. The virus or its genetic material enters the cell.
The statements accurately describes a difference between viruses and bacteria is viruses are much smaller than bacteria cells. Thus, option A is correct.
What is virus?A virus is a microscopic organism that serves as infectious agent and replicates only inside the living cells of an organism. Viruses infect all living organisms such as plants, animals, human beings including bacteria and other microscopic organism.
Virology is the branch of science which deals with the study of viruses. When virus infected a host cell rapid production can be observed and by multiplying rapidly thousands of original copy of viruses are produced.
When the virus enters into a infected cell or living cell, viruses exist in the form of independent particles known as virions. In open air viruses are non-living but when they entered into a living cell of an organism they become active and reproductive as well.
Therefore, The statements accurately describes a difference between viruses and bacteria is viruses are much smaller than bacteria cells. Thus, option A is correct.

This form of water pollution causes bacteria to multiply in the water rapidly causing people who come in contact with this water to become ill, many times with diarrhea.
Answer:
The correct answer is - water contamination.
Explanation:
Water contamination is a form of water pollution in which water is contaminated or polluted with several microorganisms and pathogens by industrial waste, sewage, animal waste.
It is contaminated when rainwater runoffs from agricultural farms, industrial and sewage dump that brings toxins, wastes, and fertilizers to the water body that help bacteria to multiply and infect the people who come in touch with it.

Strawberry plants produce offspring through asexual reproduction. Which statement is true about strawberry plants?
Question 4 options:
They are identical to the single parent.
They have characteristics of both parents.
Strawberry plants can reproduce by blastogenesis reproduction as well as syngenesis, so both statements are true.
Option (A) and (B) both are true.
How strawberry plants reproduce?Strawberry plants can reproduce by blastogenesis reproduction by sending out runners that are called stolons. So the daughter plants will be identical to the single parent.
Strawberry plants also reproduce by syngenesis reproduction by producing gametes in flowers. In this case, the daughter plants would have characteristics of both parents.
Thus, option (A)They are identical to the single parent and option (B)They have characteristics of both parents, both are true.

How do you contribute to the mass of a tree?
The living animals contribute to the mass of the tree because they release the carbon dioxide that is used by the plants for photosynthesis and later used by the cells.
What is the role of photosynthesis?Photosynthesis is the process in which the plant takes the carbon dioxide from the atmosphere and, with the help of sunlight and water, makes glucose and oxygen, which are further used by the living organisms, and releases the carbon dioxide into the atmosphere. More is the carbon dioxide released into the atmosphere by the animals, more is the rate of photosynthesizing, and more is the biomass of the plants. but if the carbon dioxide increases and the number of plants reduces, then the photosynthesis rate also reduces.
Hence, the mass of the tree increases if more carbon dioxide is released from the animals, and that is further used by the plants for photosynthesis and cellular metabolism.

In the synthesis phase of the cell cycle, a body cell copies DNA. This DNA replication occurs in preparation for which of the following processes?
In the synthesis phase of the cell cycle, a body cell copies DNA. This DNA replication occurs in S phase of Interphase. The correct option is a.
What is interphase?
Interphase is a phase of cell growth, it happens between mitosis and meiosis. It is one of the phases of the cell cycle. The series of events that occur in a cell leading to its division and DNA duplication to form two daughter cells is known as the cell cycle or cell-division cycle.
The B, C, and D periods make up the cell cycle in bacteria, which do not have cell nuclei. There are four phases in the cell cycle.
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.
