for RNA, you’ll just do the opposite of what the DNA strand says..... so A pairs with T and C pairs with G

for the actual acids, you’ll just list the names of the RNA sequence, which could be adenine, thymine, guanine, or cytosine

The explanation is as follows:

The following information should be considered:

DNA has four nucleotides namely: Adenine, Gunanine, Thymine and Cytosine. While on the other hand,  RNA has Uracil in place of THymine. The process of copying the information from DNA into RNA is called transcription, whereas translating the nucleotide sequence into amino acid sequence is called translation.

Answers

Answer:

Hypothesis: If you eat Special K cereal for 2 weeks, you will lose 10 pounds.

Independent variable: Special K cereal.

Dependent Variable: Weight lose.

Explanation:

Hypothesis: The term "hypothesis" is determined as a testable and a precise statement of what a specific researcher or experimenter predicts would be considers as the outcome of a particular study.

Independent variable: In research, the term "independent variable" is determined as a variable that is being re-organized in an experiment or research in order to see its impact on the dependent variable. Independent variable influences the dependent variable directly. 

Dependent variable: The term "dependent variable" is determined as a variable that is being measured or tested in an experiment or research by the experimenter or researcher and is directly influenced by the independent variable.

how does the concentration of electrolytes in and outside a cell control the movement of water

Answers

Answer:

Maintaining an isotonic environment for the cell ensures that the cell does not shrink or swell due to water.

Explanation:

If the cell was in a hypotonic solution, water would rush in the cell causing it to burst, and if it was in a hypertonic solution it would cause water to move out of the cell, causing the cell to shrivel. It is important that the cell is always in a solution with an almost equal electrolyte solution inside the cell

What are genes?

A gene is the fundamental structural and operational component of hereditary material. DNA is the material that constitutes genes. Some genes' sole purpose is to provide instructions for making larger molecules known as proteins. However, many genes do not contain the coding necessary to produce proteins. Genes in humans can be as small as a few hundred DNA bases or as large as more than 2 million DNA bases.

Many of your characteristics, such as the color of your hair and skin, are determined by the genes that were passed down to you.

When scientists carefully measure the lichens and agree on their thickness and how often they appear which parts of the scientific cycle are scientists using

Answers

Answer:

This question is incomplete; the complete question including the options are as follows:

During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.

When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?

A- process and facts, because they are using a systematic method to measure and then record data

B- process and facts, because they are observing lichens and air quality and describing why they are related

C- explanation and process, because they are using a systematic method to measure and then record data

D- explanation and process, because they are observing lichens and air quality and describing why they are related

The answer is A. process and facts, because they are using a systematic method to measure and then record data

Explanation:

Scientific experiments follow a series of well coordinated steps. These steps range from making observations to analyzing data. In this experiment, which involves scientists conducting a study of lichens and air quality in a part of China, a scientific cycle is being followed.

However, the scientists get to a point where they carefully measure the lichens and agree on their average thickness and how often they appear. This point is where the ANALYSIS OF DATA in the experiment occurs. Therefore, the part of the scientific cycle they are using is PROCESS and FACTS, because they are using a systematic method to measure and then record data.

what do you observe at low temperature medium temperature and high temperature​

Answers

Low temperature means it’s cold or chilly so you be observing snow at low temperature. Medium temperature is like mild breezy not too hot not too cold so you’ll be observing breezy winds. High temperature is like hotness so your be observing more sun.

The temperature of a body can be related to the energy transferred between the particles of the body. Hence, temperature is directly proportional to the energy of the particles in the sample.

The kinetic energy possessed by the particles in a sample is highest at the highest temperature attained by the body.

The kinetic energy drops as the temperature drop s from high to medium to low temperature. Hence, the low temperature samples have very low kinetic energy.

Therefore, the energy possessed by the particles of a sample is directly proportional to the temperature of the sample.

A typical steer weighs about 1100 pounds and can be processed into approximately how many pounds of edible meat by a seasoned butcher ?

Answers

The correct answer is - 430 - 450 pounds.

Explanation:

A seasoned butcher can process a steer into edible meat. A typical steer can weigh in between 1100 pounds to 1300 pounds.

This alongside the fat and bone eliminated during the cutting record for an extra 18% misfortune. In synopsis, a cow weighing 1,000 pounds on the foot will average around 430 pounds of retail cuts (steaks, ground meat, cooks, stew hamburger, and so on.)

Which molecule separates the contents inside of the cell from the contents outside of the cell

Answers

Answer:

Which molecule separates the contents inside of the cell from the contents outside of the cell

Explanation:

cell membrane

Every cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.

The molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.

Lipids represent a broad range of biomolecules made up of carbon (C), hydrogen (H) and oxygen (O) atoms.

In some cases, lipids also contain phosphorus (P), nitrogen (N) or sulfur (S).

Lipids (i.e., phospholipids and cholesterol) represent the main biomolecules of the cell membrane whose function is to separate the interior of the cell from its surrounding environment.

In conclusion, the molecule that separates the contents inside of the cell from the contents outside of the cell is LIPIDS.
