Answer:

New cell are made

Explanation:

Answer:

yes, but by gas you mean oxygen right?

Explanation:

Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Explanation:

Answer:

1. producers are the largest and consumers are the least

2. because wolves feed on both primary and secondary consumers

3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.

4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.

if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die

Answer:

the egg begins to shrink

Explanation:

During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.

Answer:

6.25%

Explanation:

Given that:

The trait of a female fruit fly that is heterozygous for red eyes = XRXr;   &

The trait of a white-eyed male is XrY_ ;

since Y is dominant y; the male trait can either be XrYR or XrYr

So, let assume that it is XrYr

Then; if each trait self crossed; we have:

XRXr = XX    Xr    XR    Rr

XrYr = XY    Xr     rY    rr

Thus, the punnet Square can be computed as:

               XX             Xr             XR           Rr

XY         XXXY       XXYr         XXYR        XRYr

Xr          XXXr         XXrr          XXRr        XRrr

rY          XrYX          XxYr         XrYR        RrYr

rr            XrXr          Xrrr           XrRr        Rrrr

∴

the percentage of offspring that would have white eyes XrY_ is:

1/16 = 0.0625

= 6.25%

Liquid because it's always moving somehow, so the particles have more kinetic energy

Answer:

1. use of the wrong antibiotic

2. use of insufficient concentration of the right antibiotic

Explanation:

MRSA means Methicillin-resistant staphylococcus aureus

VRSA means Vancomycin-resistant Staphylococcus aureus

These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.

Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.

Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:

1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.

2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.

Cell division in a cell takes place in the single-celled organisms to reproduce and pass along the genetic information of the cell. Thus, the correct option is B.

Cell division is the process of division of cell through which a parent cell divides into two daughter cells with equal genetic content which are similar to the parent cell. Cell division generally occurs as a part of a larger cell cycle in which the cell grows in size and the cell replicates the chromosomal material before it is undergoing cell division.

In the unicellular organisms, cellular division is a significant process through which a unicellular organism undergoes development and result into the formation of a new organism with genetic material which is similar to the parent cell. In the multicellular organisms, process of cellular division helps in maintaining a balance between the genetic material such as the DNA and the RNA contents as well as the nuclear and cytoplasmic contents of the cell.

Therefore, the correct option is B.

Answer: i think the Interphase because

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

Answer:

Explanation:

Regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

The body maintains a particular internal temperature irrespective of changes in the external environment, and this is possible because of the homeostasis in the body, which is important because many of the body's processes are temperature and pH sensitive, such as the enzymatic function, the alkalinity of blood, etc.

Hence, regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

Explanation:

Answer:

Many predators have adaptations that help them survive in the wild.  For example, the snake shown below has camoflauge coloring to look like its surroundings.  This gives it the element of surprise when going to attack its prey.  These adaptations help the predator in hunting for food.  Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws.  The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.

They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.

The final experiment, also known as the Waring Blender experiment, in which Hershey and Chase demonstrated that phages only injected their DNA into host bacteria and that the DNA acted as the replicating genetic element of phages, is the Hershey-Chase experiment that is most well-known.

Hershey and Chase discovered proof that phages introduced their DNA into host bacteria in the prior experiment.

Therefore, Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.

The mutation affects DNA and chromosomes by changes in the sequence of DNA or changes in the gene present on the chromosome.

The mutation is a sudden change in the structure of chromosomes or DNA. The smaller mutation affects the nucleotide base in DNA, while the larger mutation affects the genes present on the chromosomes.

The substance which causes mutation is known as mutagens. Mutation can cause problems in growth and development and affects the functioning of the body. When changes occur in chromosomes or DNA, they cause changes in the protein. Due to this, a different kind of protein is produced.

The mutation is caused by the insertion, duplication, deletion, and substitutions of a DNA sequence. Thus, mutation can affect DNA and chromosome in many ways.
