The process whereby the earth’s life changes over time through changes in genes of populations of organisms in succeeding generations is called____.a. emigration.b. mutation.c. natural selection.d. evolution.e. genetic drift.

Answers

Answer 1

Answer:

The correct answer is option : d. evolution.

Explanation:

Change in the heritable traits or characteristics of population of a organism over time by the adaption or changes in genes of such population over successive generation is known as the evolution.

These changes that cause the evolution of the biological population is caused by the process of adaption through natural selection that is the ability of the passing beneficial genes from parent to offspring.

Thus, the correct answer is option D. evolution.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins

Answers

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

C. Regulating
D. Supporting

Answers

Answer:

D. Supporting

Explanation:

Ecosystem services include provisioning, regulating, culture and supporting services.

Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.

Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.

Hence, the correct answer is "D. supporting".

Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.

Answers

Answer: Option C.

slight fluctuations that are kept within a narrow range.

Explanation:

An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).

Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.

Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?​

Answers

Answer:

"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule. "

While performing an experiment, it is important to:
a. change the control setup
b. test many different variables at the same time
c. reach a conclusion
d. record observations and measurements

Answers

Answer:

D

Explanation:

While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.

What is an experiment?

The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.

Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

When you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent

Answers

Answer:

Leading strand and Okazaki fragments

Explanation:

The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.

The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.

This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.

The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

What results if a broken chromosomal fragment becomes reattached as an extra segment to a sister or non-sister chromatid? A Duplication B Inversion C Polyploidy D Nondisjunction

Answers

Answer:

The correct answer is option A "Duplication".

Explanation:

Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.

Answers

Answer:

kills all microbes that cause disease or spoilage.

Explanation:

There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.

The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.

These mechanisms are used with surgical instruments, the operating room environment.

The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.

Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.
