Answer:
Both physical and chemical factors
Explanation:
A mutation is any alteration in the DNA sequence of the genome of a particular cell/organism. Depending on the type and localization, a mutation can be neutral, deleterious, or even beneficial for the individual that possesses it. Moreover, the mutation rate refers to the probability for a mutation to appear in a cell/organism. Exposure to physical environmental factors (e.g. ultraviolet radiation, X-rays, gamma rays, etc) and chemical factors (e.g., bromine) can increase this likelihood.
Answer:
physical and chemical factors
Explanation:
Factors that alter the critical chemical and physical characteristics of ecological systems include temperature, pH electrochemical (redox) potential, and the transparency of air and water.
The Darwinian theory of organic evolution through natural selection affected American religion by a raising awareness of the close spiritual kinship between animals and human beings. b turning most scientists against religion. c causing a revival of the doctrine of original sin. d sparking the rise of new denominations based on modern science. e creating a split between religious conservatives who denied evolution and accomodationists who supported it
Answer:
.e creating a split between religious conservatives who denied evolution and accomodationists who supported it
Explanation:
The Darwinian theory of organic evolution proposed that all forms of life evolved from more primitive life by differential survival and reproduction (i.e., by natural selection). Moreover, creationism is the religious belief that humans were created by God, whereas accommodationists refer to the persons that endorse cooperation and concession to the viewpoint of the opposition. In this case, Darwinian theory challenged the traditional religious anthropocentric viewpoint on human origins (i.e., humans descended from ape-like creatures by natural selection).

HIV binds to Helper T cells of your immune system.
A. True
B. False
Answer: True
HIV infects a type of white blood cell in the body's immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases. HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together).
Explanation:
T-cells, the thymus cells, work in a similar way but destroy infected cells rather than manufacture antibodies. In HIV infection, the body mounts a very strong antibody response in the first few weeks that partially works, bringing the viral load down from millions to, on average, about 50,000 copies/ml.
Answer:
The answer is true...
Explanation:
HIV infects a type of white blood cell in the body’s immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases.
HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together). It then takes control of the cell’s DNA, makes copies of itself inside the cell, and finally releases more HIV into the blood. HIV will continue to multiply and spread throughout the body – a process called the HIV lifecycle.
In this way, HIV weakens the body’s natural defences and over time severely damages the immune system. How quickly the virus develops depends on a person’s general health, how quickly they are diagnosed and start antiretroviral treatment, and how consistently they take their treatment

Protists represent an important evolutionary step between and A. fungi, plants B. bacteria, animals O C. single celled organisms, multicelled organisms D. plants, animals Peser Selection
Protists represent an important evolutionary step between single-celled organisms and multi-celled organisms.
Protists have similar DNA to the DNA of cyanobacteria. This similarity show the evolutionary relationship between cyanobacteria and algae in which cyanobacteria is a single celled organism whereas algae is multi-celled organism so from this discussion we can conclude that protists is an important evolutionary step between single celled organism and multi-celled organism.

Describe the interaction between the digestive and circulatory system of the earthworm.
The terrestrial invertebrate that is the tube-like organism and belongs to phylum Annelida are called earthworms.
The earthworm has a closed circulatory system and has vessels spread all over its body. The blood circulation and transport of oxygen occur through blood vessels.
The digestive system starts from its mouth towards the end till the anus. The intestine of earthworms has blood vessels that aid in absorption and in transporting nutrients and food in body parts.
The nutrients and food produced in the crop and intestine get absorbed in the vessels of the circulatory system that are present in the digestive organs.
In this way, the digestive and circulatory system interacts with each other.

give two examples of what a living thing can do once it has converted the energy from food into usable forms of energy.
Answer:
When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.
Two examples of what a living thing can do once it has converted the energy from food into usable forms of energy are growth, reproduction, and movement, and by using the energy, they survive in the ecosystem.
What is the significance of the energy from food?Energy from food can be obtained, and that energy is further used for many reasons, such as metabolism and movement, and a living organism can use it to power its muscles for movement such as running and swimming. Apart from that, the energy is used for growth and reproduction, which allow an organism to develop and produce offspring.
Hence, two examples of what a living thing can do once it has converted the energy from food into usable forms of energy are growth, reproduction, and movement, and by using the energy, they survive in the ecosystem.

Give any 2 significance of nitrogen cycle to green plant
Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is made up of nitrogen gas (N2).
Plant uptake of nitrogen compounds
Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
As part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.
Fixation
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
