D. Discarding data that does not fit with your personal expectations.

Explanation:

One of the ways in which bias can be introduced into an experiment is by discarding data that does not fit with one's personal expectations.

Bias in an experiment is the process whereby scientists alter the results of their experiment to achieve their own expected results.

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.

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.

Answer:

The correct answer is - option B. immovable joints connect my bones; movable joints allow my bones to move.

Explanation:

In the skeletal system, both immovable joints and movable joints are present and both have a distinct role in the body and skeletal system. The immovable joints are the joints that provide the stability to the bones that are connected and maintain the structure these joints also helps in protecting the organs.

Movable joints are the joints that are helpful in movement and allow bones that are connected to feely or up to a limit move.

Thus, the correct answer is - option B. immovable joints connect my bones; movable joints allow my bones to move.

Answer:

B

Explanation:

immovable joints connect bones well that a correct answer

them becoming arid desert. just took the test and got a 100 :)

Answer:

D because Iraq though the years became a dry sandy desert mostly made up of desert mountains to this day

Explanation:

A isn't right it'll be less of a desert but also less land, the mountains also only makes of a a bit of a quarter or more of the land

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.

Answer:

A single strand of DNA is a polymer of nucleic acids joined covalently between the phosphate group of one and the deoxyribose sugar of the next to for a “backbone” from which the nitrogenous bases stick out. In its natural state, DNA has two strands wound around each other in a double helix.

Explanation:

Answer:

Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer.

In mismatch repair, mistakes that happen during DNA replication are recognized, cut out and replaced. ... This mismatched base pair causes a point mutation, which you can think of as a typo in the DNA sequence of the new strand.

Explanation:

Incorrectly paired nucleotides cause deformities in the secondary structure of the final DNA molecule. During mismatch repair, enzymes recognize and fix these deformities by removing the incorrectly paired nucleotide and replacing it with the correct nucleotide.

Eukaryotes have solved the end-replication problem by locating highly repeated DNA sequence at the end, or telomeres, of each linear chromosome. In humans and other vertebrate organisms, the sequence of nucleotides in telomeres is TTAGGG, is repeated between 100 and 1000 times.

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 (  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.

Answer:

The answer is B because the sun melts the core of the comet

The sun's energy causes the comet to form a bright tail. The correct answer is A.

When a comet approaches the Sun, the Sun's energy causes various effects on the comet.

As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.

This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.

Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.

So, the correct option is A.

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
