Answer:
d. acid rain and ozone pollution
Answer:
a. Agricultural activities
Explanation:
because the other activities are the major sources of pollution. For example.. burning of fossil fuels pollute the air, storm water is a polluted one & it makes the water ways to pollute and the last one is also a pollution which is already shown as pollution in it's sentence.
How does the human brain receive messages and send signals to the body about what's happening?
Answer:
heres how
Explanation:
Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses.” Impulses rush along tiny fibers, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.

what is photosynthesis
Photosynthesis is a synthesis of compounds with the aid of radiant energy especially in plants.
Radiant energy it transmitted in the form of electronmagnetic radiation; energy that exists in the absence of matter.
Synthesis is the process of producing a chemical compound usually by the union of simpler chemical compounds.
The combination of ideas into a complex whole.
Reasoning from the general to the particular or from cause to effect.

Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Discuss what happens when an individual with 17 chromosomes mates with an individual of the same species with 16 chromosomes.
Answer:
There will be an extra chromosome in the offspring thereby leading to aneuploidy
Explanation:
Please see the attached file
How does aneuploidy lead to cancer initiation?
Answer:
Chromosomal aberrations during cell division represent one of the first recognized features of human cancer cells, and modern detection methods have revealed the pervasiveness of aneuploidy in cancer. The ongoing karyotypic changes brought about by chromosomal instability (CIN) contribute to tumor heterogeneity, drug resistance, and treatment failure. Whole-chromosome and segmental aneuploidies resulting from CIN have been proposed to allow “macroevolutionary” leaps that may contribute to profound phenotypic change. In this review, we will outline evidence indicating that aneuploidy and CIN contribute to cancer evolution.

Identify the blood type that can be transfused into anyone.
Answer:
n the United States, the most common blood type is O, followed closely by type A. If you have type O blood, you can only get type O red blood cell transfusions. But you can give your red blood cells to people with type A, B, AB, or O blood, which is why you are sometimes called a universal donor.
A negative: B negative
A positive: B positive
Explanation:
Answer:
O negative (O-)
Explanation:
It's the universal blood type

Why are sodium ions differentially permeable?
Answer:
In most cases, an ion channel is permeable only to specific types of ions (for example, sodium and potassium but not chloride or calcium), and sometimes the permeability varies depending on the direction of ion movement.
Explanation:
Hope it helps u
FOLLOW MY ACCOUNT PLS PLS
Explanation:
This transporter ejects 3 sodium ions from the inside of the cell for every 2 potassium ions it transports in, all against a concentration gradient. ... If, however, membranes are differentially permeable to the ions, an electrical potential across the membrane can arise.

Compare the overall excretory process in plants vs animals in terms of ; organs used and are they specialized?
Answer:
Stomata.
Explanation:
Plants do not have specialized excretory organs like animals. The plant body produces excess carbon dioxide and oxygen which are excreted from the plant through the small opening present on the underside of the leaves called stomata. In the process of photosynthesis, plant produces oxygen and glucose in which glucose is stored in the body whereas oxygen releases through stomata while on the other hand, in respiration process, plant produces carbondioxide gas that is also released through stomata.
What is the relationship between mass and solar energy in plants?

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
Answer:
No.
Explanation:
There is no clear evidence which indicates that cell phones will cause cancer because they emit very low intensity of radio waves but it can cause other diseases. Diseases such as brain tumor, male infertility and ear hearing function can be adversely affected by using cell phones due to the radio wave they emit. So we can say that cell phones will not the cause of cancer disease.
Answer:
No, the increasing number of cell phones will not the cause of cancer because it emits low intensity of radio waves. Radiations such as x-rays, gamma rays, alpha particles, beta particles, and neutrons are responsible for causing damage to the cell and the main cause of cancer. High intensity of radio waves heats up the cells not causing cancer disease so we can conclude that the increasing number of cell phones will not cause cancer disease in humans.

Why aren't human populations evolving to produce immune systems that are able to fight off MRSA and other "superbugs"?
Answer: There are genes that code for different cell receptors that detect foreign substances. And for the immune system to fight these superbugs, the genes encoding these receptors must mutate and evolve. Humans have a slow rate of evolution, slower than bacterial evolution. Then not only human genes mutate at a very slow rate, but insect genes mutate very fast and can improve their strategy to evade the immune system.
Explanation:
A mutation is a random change in the nucleotide sequence or in a gene, which produces a variation in its characteristics and which is not necessarily transmitted to the offspring. They occur spontaneously by the action of mutagens, which are physical, chemical or biological agent that changes the genetic information of an organism and thereby increases the frequency of mutations above the natural level. In multicellular organisms, mutations can only be inherited when they affect the reproductive cells, called gametes (egg and sperm) A consequence of mutations can be, for example, a genetic disease, or it can also be a favorable improvement such as being able to fight against a virus. However, even if in the short term mutations could detrimental, they are essential for our long-term existence becuase without mutations there would be no change, and without change life could not evolve.
The immune system is the body's natural defense against infections, such as bacteria and viruses. The body attacks and destroys invading infectious organisms by the coordinated action of cells and proteins. Any substance or compound produced by an organism is a potential antigen when it is recognized as foreign by the immune system of another organism, whether it is of the same or a different species. In addition, the genes code for different cell receptors that detect these foreign substances. And for the immune system to fight these superbugs, the genes encoding these receptors must mutate and evolve. But, humans have a slow rate of evolution, slower than bacterial evolution. Then not only human genes mutate at a very slow rate, but insect genes mutate very fast and can improve their strategy to evade the immune system. Therefore, the human population may not have mutations that improve the immune system to help it fight againts these superbugs.
