Which part of the microscope is used to make small adjustments in the image of an object?

A)Eyepiece
B)Fine Adjustment
C)Coarse Adjustment
D)Objective lens

Answers

Answer:

The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.

Explanation:

In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied.  This means making minimal adjustments in order to better observe the microscopic image.

After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.

The other options are not correct because:

    A. Eyepiece  is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.

    C. Coarse Adjustment  is the rough magnification, used for the initial approximation of the image.

    D. Objective lens enlarges and defines the image of the sample on the slide.

which one of the following is not an organic molecule found in living organisms?

Answers

Answer:

Well you weren't very clear, there were no answer choices. But If I had to say I would say, sodium Chloride. Organic compounds are proteins, nucleic acids,carbohydrates, and lipids. Sodium chloride is none of these, therefore it's the answer. I apolagize if i am wrong, It was slightly unclear. I might be wrong do not take my word, if you are unsure.

The correct answer is that minerals are not organic molecules found in living organisms. While they play important roles in biological processes and are required for the proper functioning of the body, they are considered inorganic substances. The last option is correct.

In living organisms, organic molecules are essential for various biological processes. They are composed primarily of carbon atoms bonded with other elements such as hydrogen, oxygen, nitrogen, and sometimes sulfur and phosphorus. Organic molecules found in living organisms include carbohydrates, proteins, and lipids. Carbohydrates are a class of organic molecules that serve as a primary source of energy. They are made up of carbon, hydrogen, and oxygen atoms and are found in various forms, including sugars, starches, and cellulose. Carbohydrates play crucial roles in energy storage and provide structural support in cells and tissues.

Why must dioecious organisms find mates in order to reproduce?

Answers

Answer:

Most familiar is biparental reproduction (sometimes called dioecious reproduction). ... Dioecious reproduction leaves the greatest genetic variability among offspring (an advantage under changing conditions or in competition or when faced with disease), but the organisms must find mates.

Most of the dioecious organisms find mates  in order to reproduce because they are unisexual in nature and they always need a partner to reproduce.

What are the two types of reproduction ?

The two types of reproduction are sexual and   It is the mating between two partner that happens in the case of sexual reproduction. In the case of asexual it is the single parent giving rise to its younger ones.

In the case of dioecious animals that is the organisms bearing either of males or either of females and in this case it is hard for organisms to give birth to their younger ones individually.

dioecious animals need to find the partners as per the compatibility and the specificity. The individuals with the compatibility and the specific orientations give rise to their younger ones and this process is called as reproduction.

Carrie is conducting an experiment on a solution. The solution’s initial pH is 10. Then, as Carrie gradually adds Compound X into the solution, the pH decreases to 5. Which is the most likely identity of Compound X? *

Answers

Answer:

Compound X must be an acid

Explanation:

Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.

What impacts would suburban development have on undeveloped deciduous forest and meadow ecosystems?

Answers

Answer:

Impacts of  suburban development on undeveloped deciduous forest and meadow ecosystems are - : loss of biodiversity , excessive land use , deforestation , degradation of air quality , increase in the amount of greenhouse gases , therefore leading to environmental loss .

Explanation:

SUBURBANIZATION -:  Suburbanization is a demographic change, resulting in the creation of (sub)urban sprawl, from core urban areas to suburbs. Low-density, peripheral urban areas are increasing as a consequence of the migration of households and companies out of the city centers. (Urbanization, which signifies a demographic change from rural areas to urban centres, is inversely related to suburbanization.)

Within the central urban area, many residents of metropolitan regions work and prefer to live in satellite communities called suburbs and commute to work by car or mass transit. Others have taken advantage of advances in technology to operate from their homes.

Environmental Implications   -: This can have negative effects on the community with the growth of suburbanization and the spread of individuals living outside the city. Suburbanization has been related to an increase in the mileage of automobiles, an increase in land usage, and an increase in the use of residential electricity. These suburbanization factors then induced air quality deterioration, increased use of natural resources such as water and oil, and increased quantities of greenhouse gases. This causes increased use of oil and gas as well as an increase in pollution as the use of cars to drive to and from the workplace grows. This will then cause air pollution and degrade the air quality of a region with a rise in emissions from vehicles. Suburbanization is increasing, leading to an increase in housing growth, which causes the consumption of land and land available to increase.

When pyruvic acid loses carbon dioxide it becomes what acid?

Answers

Answer:

Acetyl CoA

Explanation:

After glycolysis but prior to the beginning of the citric acid cycle (also called the Kreb's cycle), pyruvic acid (pyruvate) loses a molecule of carbon dioxide. The resulting molecule is called Acetyl CoA. This is called pyruvate oxidation and is an important intermediate step in aerobic respiration.

Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the addition of a certain amino acid to a specific tRNA. c The biological role of restriction enzymes is to: A) aid recombinant DNA research. B) degrade foreign DNA that enters a bacterium. C) make bacteria resistant to antibiotics. D) restrict the damage to DNA by ultraviolet light. E) restrict the size of DNA in certain bacteria.

Answers

Answer:

C) are sequence-specific DNA endonucleases

Explanation:

Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.

while fat molecules are used immediately.

B) O ATP molecules are used for long-term storage, while fat is used for
immediate energy
C) O Fat molecules are stable and can be stored for a long time, while ATP is not.
D) O Fat molecules are unstable and can be stored short-term, while ATP
molecules are stable and stored long term.

Answers

Answer:

C) Fat molecules are stable and can be stored for a long time, while ATP is not.

Explanation:

ATP is short-term energy, and fat is long-term energy and is used when when there is no more energy. Fat molecules are also highly stable because of the many covalent bonds

Answer:

C, i think

Explanation:

ATP is short term storage due to the fact that it is produced rapidly and used up just as fast in cells. Fat is long term, usually when there is no energy, fat is burnt up (during exercise is the most common) and used for energy
