Answer:
The correct answer is - b. Air pollution from the excess fertilizers
Explanation:
In long term using excess amount of fertilizer than requirement will lead to several condition such a soil acidity, soil degradation, soil leacing, eutrophication of waterways and many but more improtant is green house gases and air pollution.
Using the excess amount of fertilizer does not help in increasing crop yield but gives negative impact. Using fertilizer more than requirement wil lead to release of toxic and harmful gases in atomosphere and fuming.

Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.

Skim the headings and bold words in this section. Write four steps scientists might take to solve a problem.
Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.

Describe the structure of the conjugated protein
haemoglobin, with reference to the levels of protein
structure.
Answer: Answer below, hope this helps! :D
Explanation:
A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

You might then also realize that the new method, at least on paper, may have additional applications. ... which makes the technology attractive to yet more scientists.
Explanation:
Hoped I helped you out please mark me brainliest!!!
With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.
What is a microscope?A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.
In most cases, the light is focused on the sample by passing it through a condenser.
After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.
The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.
Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

Explain the difference between how light falls on the Earth near the Equator or the Poles
Answer:
Explanation:
The normal amount of solar radiation reduces from the Equator to the poles. This is because the low latitudes (near the Equator deliver relatively large amounts of radiation all year, and at high latitudes (near the poles), the more slanting angle of the Sun’s rays together with long periods of darkness in the winter, result in a low amount of received radiation.

Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.
If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.
If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.
