Answer:

im pretty sure its B

Explanation:

Explanation:

When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.

this is because water expands as it gets cold hence floating leaving the unfrozen water dense

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.

A

Explanation:

tilted towards sun....

Answer: There are pretty obvious differences between plants and animals, but – at the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix” that looks like a twisted ladder. What’s more, all DNA molecules – in both plants and animals – are made from the same four chemical building blocks – called nucleotides.

Land - Lion

Water - Sealion

Flies - Bees

Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.

The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.  

A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.

Some traits appear more often because they are dominant. Dominant traits win out over recessive genes.

Answer:

C

Explanation:

The skeleton relies upon the contraction and relaxation of muscles which are attached to bone in order to move. The muscular system is made up of three types of muscle, one of which is responsible for the movement of bone. To add to the confusion, the relationship between both muscles and bones is often lumped together as the musculoskeletal system, but to be sure, they are unique in their own ways.

In summary, bones can't move on their own, and therefore movement cannot be the skeletal system's function.

The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.

Sickle cell anemia is a hereditary disease which provides less oxygen to cells due to a change in the shape of red blood cells which fails to carry oxygen to cells.  

In sickle cell anemia, the effected or mutated part is the beta gene that normally makes hemoglobin but due to the mutation in the amino acid, the protein formed is defected and fails to perform its normal function.

As mentioned above, it is a heredity diseases and pass from generations to generations.If Mary has a child with someone who does not have a mutated sickle cell allele, there is a 25% probability that the child will be a carrier.

Therefore, The statement is true about Mary is If Mary has a child with someone who has sickle cell disease, there is a 50% probability their child would have the disease. Thus, option A is correct.

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.

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.

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%
