3. What is the relationship between
adaptation and natural selection?

Answers

Answer 1

Answer:

hope it helps...

Explanation:

Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.

A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.

Explanation:

Answer:

An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.

Explanation:

An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond.

A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?

Answers

Answer:

That its a nuetral

Explanation:

In the given case of water molecule, the charges shows that it is a polar molecule.

What is a polar molecule?

It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.

When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.

Thus, the charges shows that it is a polar molecule.

How do the circulatory and nervous systems work together to maintain homeostasis | ASAP

Answers

The cardiovascular system helps maintain homeostasis by continually supplying the central nervous system--the brain and spinal cord--with oxygen and glucose. Brain cells start dying after just one minute without oxygen. The brain is the control center for all of the body's homeostatic processes.

Answer:

The circulatory and the nervous systems work together to maintain homeostasis because the circulatory system gives your brain a lot of oxygen and glucose while your brain regulates your heart rate and blood pressure. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain  homeostasis.

the difference between prokaryotic and eukaryotic gene regulation

Answers

Answer:

READ THIS

Explanation:

To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.

Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level.

Eukaryotic cells, in contrast, have intracellular organelles that add to their complexity. In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm. The regulation of gene expression can occur at all stages of the process (Figure 1). Regulation may occur when the DNA is uncoiled and loosened from nucleosomes to bind transcription factors (epigenetic level), when the RNA is transcribed (transcriptional level), when the RNA is processed and exported to the cytoplasm after it is transcribed (post-transcriptional level), when the RNA is translated into protein (translational level), or after the protein has been made (post-translational level).

Answer:

Prokaryotic gene expression is primarily controlled at the level of transcription. Eukaryotic gene expression is controlled at the levels of epigenetics, transcription, post-transcription, translation, and post-translation.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival

Answers

Answer:

Explanation:

A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?

Answers

Answer:

1. ATP will increase

2. NADPH will increase

3. Sugar will decrease

Explanation:

Had the same problem

The effect of temperature on these molecules are ;

ATP will increase NADPH will also increase  while Sugars will decrease

ATP (  Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.

NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.

Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

A scientist grew an Elodea plant in a freshwater aquarium. She removed a leaf from the plant and placed the leaf in a hypertonic solution containing 8% salt in order to observe what happened to the cells within the leaf. When she looked at the cells under a microscope, she noticed that the cells in the leaf shrunk. Which statement best explains what caused the cells to shrink?

The hypertonic solution caused the water in the cell to move from the cytoplasm into the nucleus.
The salt moved from the hypertonic solution into the cell and chemically bonded with the water.
The salt within the cell moved through the cell membrane into the solution with the higher salt concentration.
The water within the cell moved through the cell membrane into the solution with the lower water concentration.

Answers

Answer:

The water within the cell moved through the cell membrane into the solution with the lower water concentration.

Explanation:

According to this question, a scientist removed the leaf of a plant originally grown in a freshwater aquarium and placed it in a hypertonic solution containing 8% salt. Firstly, A HYPERTONIC SOLUTION is that solution which contains a higher solute concentration than that of the intracellular environment.

Due to this concentration gradient i.e. difference in concentration, OSMOSIS process will be triggered. Osmosis is the movement of water from the region of low solute concentration (the leaf cells) to a high solute concentration (the salt solution) via a semi-permeable membrane (cell membrane).

Therefore, osmotic process causes water to move from the leaf cells into the salt solution via the cell membrane. hence, causing the cells of the leaf to shrink.

B: A phosphate group is removed from ADP to form ATP.
C: A phosphate group is added to ADP to form ATP.
D:A phosphate group is removed from ATP to form ADP.

Answers

The answer is “C.” ADP stands for adenosine diphosphate—di meaning two. When you add an extra phosphate, the di becomes tri (2 to 3). Therefore, adenosine TRIphosphate, or ATP, is released from cellular respiration.

What is cell wall?

Cell wall is the rigid outer layer of the cell; this forms a protective wall made mostly of cellulose, a structural carbohydrate. It  maintains the shape of the cell by preventing water loss. Vacuole a phospholipid membrane bound organelle plays a structural role in the cell; supports the cell membrane by exerting turgor pressure.

Arranged in a phospholipid bilayer, the cell membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Therefore, Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins.
