Answer:

Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant.

Explanation:

Photosynthesis could be responsible for the rise in the amount of oxygen in the seas and atmosphere near the beginning of the Cambrian. This rise of oxygen concentration allowing the evolution of larger animals having complex respiratory and circulatory systems. So we can conclude that evolution in the physical and genetical characteristics of animals occur during the Cambrian Explosion.

The role of scientific knowledge in society is that the advances in scientific knowledge can be beneficial to society if applied responsibly. Thus, the correct option will be B.

Scientific knowledge is referred to as a generalized body of laws and theories which are used to explain a phenomenon or a behavior of interest that are acquired by people using the scientific method and knowledge.

Laws are observed patterns of phenomenon or behaviors, while the scientific theories are systematic explanations of the underlying phenomenon or the behavior observed.

The role of scientific knowledge in society is that the advances in the scientific knowledge can be beneficial to the society as a whole if applied responsibly.

Therefore, the correct option will be B.

Explanation:

Complete question:

Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species – A, B, C, D. The relationship between species can be determined by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.

Which two known plant species is the unknown plant species most closely related to?

Answer:

Species C is the most closely related, followed by species D.

Explanation:

Gel electrophoresis technique is used to separate different fragments of DNI, RNA, and other macromolecules or proteins, concerning their size/weight and charge.

Gel electrophoresis of DNI lets us visualize how many different fragments of the molecule are present in a sample and how they differ from each other. The presence of fragments of the same size will be distinguished as a line named band. Each band represents many DNI fragments of similar size placed in the same position. The result of the gel electrophoresis will be different bands in different positions according to their sizes. The biggest ones will not migrate in the gel as much as the smallest ones.

In the exposed example we can assume that the most closely related species is C. The second most similar is species D.

The gel electrophoresis of the DNA from the unknown plant species resulted in five different bands, which means five types of fragments of different sizes.

Answer:

Reduce the mass and measure the speed of pendulum.

Explanation:

First measure the swings of the pendulum at its original weight. After that some weight is removed from the pendulum and again measure the number of swing of pendulum at specific time period. We have to reduce mass of pendulum and then measure the number of swings. In this way, this experiment moves forward and we can find out the impact of mass on the speed of pendulum.

Answer: D. Kingdom Animal

Explanation: Among other animal characteristics, humans can move on their own, so they are placed in the animal kingdom. Further, humans belong to the animal phylum known as chordates, because we have a backbone. The human animal has hair and milk glands, so we are placed in the class of mammals.

Answer:

D. Kingdom Animalia

Explanation:

Human beings belong to kingdom Animalia. So, option (D) is correct.

Answer:

In the leaf, excess glucose is rapidly converted to starch, so we test leaves for starch to show that photosynthesis has happened, rather than testing for glucose. We often indicate that light and chlorophyll are required for the process by adding them to the equation near the arrow.

Answer:

j

Explanation:

since brown eyes are more dominant than blue eyes chances of it is 3/4

Answer:

The answer is J. 25%.

Explanation:

In this problem, we know brown eyes are dominant to blue eyes.  We can let the dominant allele for brown eyes be represented by "B" and the recessive allele for blue eyes be represented by "b".  Since it is given that both parents are heterozygous, we know that they must have the genotype Bb.

When two Bb individuals are crossed, the offspring will be 1 BB : 2 Bb : 1 bb, or 3 brown : 1 blue ratio.  Therefore, 1/4 of the offspring will have blue eyes, which represents 25%.  Thus, the correct answer is choice J, 25%.

Answer:

The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Explanation:

If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.

If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.  

The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.  

If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).  

But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

The gluteus maximus is the largest muscle in the human body. Its role in maintaining the body's trunk in an upright position makes it big and strong.

Muscles are defined as a collection of muscles that contract together to generate force.

Muscle is coordinated systems of contractile tissue for better performance.

It can also be defined as an organ made of muscular tissue that moves in a specific way when it contracts.

A person's muscles enable them to move, speak, and chew.

They manage digestion, respiration, and heartbeat.

Other, seemingly unrelated systems like regulating body temperature and vision also depend on the muscular system.

There are three types of muscles.

Thus, the largest muscle in the human body is the gluteus maximus. Its role in maintaining the body's trunk in an upright position makes it big and strong.

B. Isotonic solution

C. Hypotonic solution

D. Both A and C

then your answer is:

Correct option is - A

Hypertonic solution

A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.
