Why is cooperative binding of hemoglobin adaptive?

Answers

For example, when an oxygen atom binds to one of hemoglobin's four binding sites, the affinity to oxygen of the three remaining available binding sites increases; i.e. oxygen is more likely to bind to a hemoglobin bound to one oxygen than to an unbound hemoglobin.

A scientist finds that a sample of matter contains three types of atoms. The sample can be any of the following, except:
A. compound
B. molecule
C. element
D. mixture

Answers

Answer:

D. mixture

Explanation:

because the mixture is not part of an atom

As per the given scenario, the sample can be any of the following, except element. The correct option is C.

What is an element?

A substance that is unable to broken down chemically into smaller molecules.

An element is made up of atoms with the same atomic number, which means that each atom possesses the same count of protons in its nucleus as the other atoms in the element.

A chemical compound is a chemical substance made up of many identical molecules made up of atoms from multiple elements that are held together by chemical bonds.

A molecule made up of only one element's atoms is thus not a compound.

A scientist discovers three types of atoms in a sample of matter. Except for elements, the sample can be any of the compound, molecule or mixture.

Thus, the correct option is C.

What is the difference between near surface ozone and high altitude ozone?

Answers

The difference between near-surface ozone and high altitude ozone is that high altitude ozone is adequate ozone as it is a UV shield and the surface zone is destructive ozone as it is harmful to life forms.

What are the major reasons responsible for ozone depletion?

The major reasons for ozone depletion include the excessive accumulation of greenhouse gases, CFCs, propellents, manufactured chemicals, etc.

High altitude ozone is found at the topmost height in the region of the stratosphere, while surface ozone is found just above the troposphere.

Therefore, it is well described above.

Genetic engineering  is the process by which scientists choose a particular group of genes and insert them into an organism in such a way that the resulting features will be beneficial to the organism. Therefore, option (B) is correct.

What is genetic engineering?

The modification and manipulation of an organism's genes through technology is known as genetic engineering, often referred to as genetic modification or genetic manipulation.

Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating new DNA. Therefore, option (B) is correct.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?

Answers

Answer:

Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.

Explanation:

Homologous chromosomes exchange genetic material during the process of meiosis.

What is Meiosis?

Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.

These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.

Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).

Thus, homologous chromosomes exchange genetic material during the process of meiosis.

Answers

Answer:

Explanation:

https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession

The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.

Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.

In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.

The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.

The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.

Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.
