What is the meaning of ecosystem?It is biological system is a geographical region in which plants, animals, and other organic entities, as well as climate and environment, work together to form an air pocket of life.
As a result of deforestation, the ecosystem is likely to change in the following ways:
Loss of habitat: Deforestation is the destruction of forests, which results in the extinction of many forest-dwelling species.Reduced biodiversity: Deforestation reduces biodiversity in the ecosystem because many forest species are unable to adapt to the new conditions and may become extinct.Thus, the correct options are C and D.

Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
After TELOPHASE II of meiosis, what is the chromosomal makeup of each daughter cell?
Diploid, and the chromosomes are each composed of two daughter cells
Diploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of two daughter chromosomes
plz remember its telophase 2 not 1
Answer:
Haploid, and the chromosomes are each composed of a single daughter chromosome
Explanation:
Meiosis is a type of cell division that reduces the chromosomal number of the daughter cells by half. Meiosis produces four daughter cells, which have half of the chromosomes of the parent cell. Meiotic process occurs in two division steps i.e. meiosis I and meiosis II, which each involves four stages namely: prophase, metaphase, anaphase and telophase.
- During meiosis I, homologous chromosomes (similar but non-identical chromosomes from parent), are separated into opposite poles while
- During meiosis II, sister chromatids (replicated chromosomes) separate into opposite poles.
Based on the above explanation, after TELOPHASE II of meiosis II, each daughter cell will be HAPLOID (n), and the chromosomes are each composed of a single daughter chromosome.

Please mark brainliest.
Respiration is the process of inhaling oxygen and exhaling carbon dioxide. Covering a glass prevents the oxygen to enter and can use to test anaerobic respiration. Thus, options 1. a and 2. b are correct.
What is anaerobic respiration?Anaerobic respiration is a process that uses electron acceptors to produce energy by breaking glucose or other sugar molecules. Unlike aerobic respiration, it lacks the use of oxygen for metabolic reactions.
This occurs in the absence of oxygen and occurs in the cytoplasm with the help of oxidizing substances like nitrate, fumarate, sulfate, etc. to produce less ATP compared to aerobic reactions of respiration.
Therefore, covering a glass prevents the entry of oxygen and can be used to observe the anaerobic respiration by some microbes.

Which cell replicates via meiosis?(1 point)
sperm cell
heart cell
skin cell
red blood cell
thanks!!
Answer:
Sperm cell
Explanation:
Because it is a reproductive cell and in one of the stages of foetus growth is meiosis so this cell undergoes meiosis to pass that stage
Meiosis is the process by which cells divide into four haploid daughter cells.Sperms are the cells that replicates via meiosis. Option A is correct.
Meiosis:
It is the process by which cells divide into four haploid daughter cells.
The daughter cells contains half of its parents chromosomes.The daughter cells are genetically different from the parent cells.It is occur in the germ cells of the organisms to produce gametes like sperm and ovum.Therefore, sperms are the cells that replicates via meiosis.

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.

explain natural selection and how it was demonstrated in this lab(website)
Hello. It is not possible to access the website you are referring to, but I will try to help you in the best possible way.
Natural selection is the term created by Chales Darwin to compose a theory of biological evolution. According to this term, living beings that have characteristics favorable to their survival, in relation to the environment in which they live, are more likely to survive and pass these characteristics on to their descendants, while those that do not have these characteristics are more likely to die. .
An example of this can be seen in a population of lizards that live in environments with a lot of grass. According to natural selection, green colored lizards would have better advantages of surviving because they would be camouflaged in the grass and would not be seen by predators, unlike red lizards, which would be easily identified and captured by predators. therefore, the population of red lizards would decrease until it ceased to exist, while the population and green lizards would survive and generate other green lizards.
