Where are steroid receptors generally located and where do they bind the steroid hormone once it enters the cell:____________
A. They are located and bind the steroids in the middle of the cell membrane
B. They are located and bind the steroids in the cytoplasm
C. They are located and bind the steroids on the intracellular membrane surface
D. The receptors are located in the cytoplasm but they bind their ligands in the lysosomes.

Answers

Answer: B. They are located and bind the steroids in the cytoplasm

Explanation: Steroid hormones are a class of organic compounds, typically lipids. They bind to protein receptors in the cytoplasm or nucleus of the target cell and thus, their receptors are located inside target cells where they function as ligand-dependent transcription factors. This is to say that hormone-receptor complex formed on binding to DNA activates specific genes that increases production of proteins.

Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.

Answers

Answer:

Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.

how would you describe cellular respiration to a younger child?

Answers

Answer:

Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy.

What happens to the total blood flow during heavy exercise compared to at rest?

Answers

Blood flow is greater when you exercise because the blood vessels in your muscles dilate. Imagine water flowing through a fire hose compared to a garden hose. Adenosine triphosphate, or ATP, is the way your body uses biochemicals to store and use energy. When ATP gets used up in working muscles, the muscles themselves produce metabolic byproducts (for example, adenosine, hydrogen ions and carbon dioxide). As these byproducts leave the muscle cells, they cause small, thin-walled blood vessels (capillaries) within the muscle to expand or dilate, which is called vasodilation. The dilated capillaries allow increased blood flow, which delivers more oxygenated blood to the working muscle.

The function of oxygen in aerobic respiration is to:
a) carry hydrogen ions from the Krebs cycle to the electron transport chain
b) bind electrons and hydrogen ions at the end of the electron transport chain
c) attach a high energy phosphate group to ADP
d) form carbon dioxide in the Krebs cycle
e) donate electrons to NADH to make it release a hydrogen ion

Answers

Answer:

Aerobic respiration uses oxygen to break down glucose, amino acids, and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles.

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X

objective by raising the oil objective a little to avoid the damage to objective lens. Critique his

technique. (1 pt.)

Answers

Answer:

See the answer below

Explanation:

In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.

For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

Explanation:

When a branch is detached from a tree, water is being lost through the porous open area. After some time, a callous formation of new tissues starts to appear on the open surface to terminate further loss of water. The osmotic pressure in the leaves gets reduced as they no longer contain enough water, while the stem is being filled with water due to the network of capillaries.

What is the chemical reaction that lactase catalyzes?

Answers

Answer:

galactose and glucose

Explanation:

Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose hope this worked :)

The chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose. The reaction is as follows:

Lactose → Glucose + Galactose. (in the presence of Lactase).

What is a Chemical reaction?

A chemical reaction may be defined as a process through which one or more substances known as the reactants are significantly transformed into one or more different substances known as the products in the presence of enzymes of energy.

Lactose is a type of disaccharide which dissociates into glucose and galactose. It is similar to maltose which in presence of an enzyme maltase gives two different compounds of glucose and sucrose in presence of an enzyme sucrase converts into glucose and fructose.

Therefore, the chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose.

C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.

Explanation:

Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription.  Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme.  Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.

What are DNA sequences?

The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are same.

The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine.

But in RNA, it is uracil with adenine. Guanine and cytosine are the same. So the adjacent base pairs will be:
