Heterotrophic organisms used the process of fermentation to nourish. What is fermentation? It is a chemical process that requires oxygen. It is a chemical process in which sugar molasses is ingested. It is a chemical process which enables heterotrophs to obtain energy without oxygen

Answers

Answer 1

Answer: It is a chemical process which enables heterotrophs to obtain energy without oxygen. Heterotrophic organisms undergo fermentation when oxygen is not available. The process converts carbohydrate (sugar or starch) into an acid or alcohol.

Explain the differences between the three ways of heat transfer, conduction, convection, and radiation.

Answers

Answer:

The differences between these three ways of heat transfer are that conduction is the transfer of thermal energy through direct contact, convention is the transfer of thermal energy through the movement of liquid or gas, and radiation is the transfer of thermal energy through thermal emission. As you can see, each way of heat transfer has a different way of moving through objects.

What is control, constants, independent and dependent variable, experimental and control group?

Answers

Final answer:

Control, constants, independent and dependent variable, experimental and control group are important concepts in an experiment.

Explanation:

Control: In an experiment, the control is the group or condition that does not receive any treatment or manipulation. It serves as a baseline for comparison. Constants: Constants are the factors or conditions that remain the same in both the control group and experimental group(s). They are kept constant to ensure that any observed effects are due to the independent variable only.

Independent Variable: The independent variable is the factor or condition that is intentionally changed or manipulated by the researcher in an experiment. It is the cause of the effect being studied. Dependent Variable: The dependent variable is the factor or condition that is measured or observed in response to changes in the independent variable. It is the effect being studied.

Experimental Group: The experimental group is the group or condition in an experiment that receives the treatment or manipulation of the independent variable. The effects on this group are compared to those of the control group. Control Group: The control group is the group or condition in an experiment that does not receive any treatment or manipulation. It is used as a comparison to assess the effects of the independent variable.

Final answer:

In experimental design, a control is a benchmark group, constants are factors that remain the same, the independent variable is the manipulated factor, the dependent variable changes in response to the independent variable, an experimental group is exposed to the independent variable, and a control group is not.

Explanation:

These terms you've asked about are all key elements in an experimental design in the area of biology or other sciences. The control refers to a group in an experiment that is not exposed to the treatment or variable being tested, serving as a benchmark to measure how the other tested subjects do. Constants are factors in an experiment that remain the same throughout all experimental groups. The independent variable is the factor that the experimenter manipulates or determines, while the dependent variable is what changes in response to the independent variable. An experimental group is exposed to the independent variable and the control group is not. They are compared to determine the effect of the independent variable. For example, if you were testing if sunlight affects plant growth, the amount of sunlight would be the independent variable, the plant growth would be the dependent variable, the group of plants exposed to sunlight would be the experimental group, the group of plants not exposed to sunlight would be the control group and constants would possibly include the type of plant and watering schedule.

Determine the most stable secondary structure that can be formed from the RNA oligonucleotide 5’-GAGUGCGCGAGCCUCU-3’. Consider only Watson-Crick base-pairing

Answers

Complementarity is achieved through interactions between nucleobases. In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). RNA secondary structure is achieved when two regions of one strand base pair and form a double helix.
Respecting the rule of complementarity and base-pairing, some of the bases will pair and some will not, as it can be seen on the image. The stability depends on helix length, base composition, and the number of mismatches.

Answers

The two given terms congenital and strangulated are related to the surgical procedure which is known as hernioplasty. Hernioplasty involves the surgery of hernia, in which the organ is repaired by putting a mesh over the weakened portion of it. Hernia can be defined as the medical condition when a part of the internal tissue, or an organ breaks through a hole in the overlying muscles.

Hence, the answer is 'hernioplasty'.

Answer:

These two terms are related to Hernia repair, hernioplasty,

herniorrhaphy

Explanation:

Hernia repair or hernioplasty or herniorrhaphy represents the same terminology and it is a form of surgery which is done usually when a hole occurs in a muscle due to the break down of an organ or tissue. In this surgery, the displaced tissue is brought to its appropriate position.

Strangulation of hernia is done when any part of an organ or tissue stuck inside hernia thereby blocking the blood supply.

While Congenital hernia surgery is done when a part of abdominal organ moves below the hernia sac, .

Why is carbon so abundant in living things when oxygen is the most abundant element on Earth? a. Carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.b. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gasesc. Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits.d. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.
