D. Solution

Explanation:

Just took the test :)

Solution types of weathering requires the presence of water.  Thus option D is correct.

The process in which break down or disintegration of rock surface occurs due to natural occurring process like rains, snow, wind, or sunshine, is called as weathering.

The origin of weathering may be due to continuous biological, chemical, and physical processes on rocks, wood, soils surface or it may due to soil erosion which occurs with the movement of rocks, minerals, snow, wind etc.

Other physical factors include pressure where as one of the chemical factor include carbonation occur between water and carbon resulted in dissolving rocks area.

When rain water combines with carbon dioxide form carbonic acid, which is then reacts with calcium carbonate of  rocks and minerals leads to rock weathering.

As the process of carbonation occur in presence of water, Hence Thus option D is correct.

Answer:

B. He has no E alleles.

Explanation:

In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.

Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.

Why not C: If he has no recessive alleles, EE, he would have detached earlobes.

If a boy is born with connected earlobes, he has no E alleles because the allele for detached earlobes is dominant (E), whereas the allele for attached earlobes is recessive (e). So, the correct option is B.

A dominant allele is one that will overpower a recessive allele's expression. Hence, only the trait linked to the dominant allele is manifested when a dominant allele and recessive allele coexist in the genotype of offspring. Consequently, for a recessive allele phenotype to manifest, both of the recessive allele must be present in the progeny.

A recessive allele causes connected earlobes (e) while the dominant earlobe detachment allele (E)

A child with the EE genotype would have disconnected earlobes.

As features of dominant alleles are manifested in heterozygous genotypes, offspring with the Ee genotype would also have disconnected earlobes. Only the child with the ee genotype would have connected earlobes. A homozygous recessive genotype is genotype ee.

Thus, the correct option is B.

Answer:

According to big bang model, the universe was born during a period of inflation that began about 13.8 billions years ago.  Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size.

Initially the universe was permeated only by energy, some of the energy congealed into particles, which assembled into light atoms like hydrogen and helium.

At first the atoms turned into galaxies, then stars and then other elements were forged.

Explanation:

These are what happened when the universe was forming.

Answer

:Photosynthesis can be explained in four simple steps, as follows.

Step 1:  

The plant gathers sunlight from the chlorophyll in the cells to convert into energy.

Step 2:

The light energy then reactions and forms hydrogen and oxygen.

Step 3:

The hydrogen joins with carbon dioxide and create sugars.

Step 4:

The sugar is then separated, some to be used as the structure in the cell wall, and some stored in the ATP for later use.

Answer:

DNA is transcribed into RNA and RNA is translated into proteins.

Explanation:

The central dogma of biology explains how gene is expressed in living organisms. Genes are segments of DNA that encodes or carry information for useful products called PROTEIN. However, these genes needs to be expressed. Gene expression occurs in two stages viz: transcription and translation.

Transcription is the first process of gene expression involving the synthesis of a RNA molecule from the gene-containing DNA molecule i.e. DNA is transcribed into RNA.

Translation is the second process of gene expression that involves the synthesis of an amino acid sequence from the information contained in the RNA transcript. These amino acid sequence forms the PROTEIN. Hence, RNA is translated into protein, which is responsible for certain phenotypes.

Answer:

A. Fever

Explanation:

Fever is part of the nonspecific immune response. Therefore option A is correct.

Fever serves as a defense mechanism against infections. When the body raises its temperature, it creates an environment that is less favorable for the growth and reproduction of many pathogens.

Higher temperatures can also enhance the activity of immune cells, such as white blood cells, allowing them to function more efficiently in fighting off the infection.

Fever is triggered by the release of certain chemicals, such as cytokines, by immune cells in response to the presence of pathogens.

These chemicals act on the hypothalamus in the brain, which regulates body temperature, causing it to increase.

Thus, fever is a physiological response of the body to infection or inflammation and is considered a part of the nonspecific immune response.

Answer: The casual relation is a cause and effect relation whereas the correlation is when the two variables are related based on two or more parameters.

Explanation:

A casual relationship can occur in between the two events, the first occurs before the other. The first one is cause and the other one is effect. A correlation can be defined as the relation between the two variables. It does not imply causation. It can be defined as the causal relation between the two variable that are correlated.

Answer:

The difference between causal and correlational relationships is as following:

A correlational relationship is defined as a measure of relationship between two variables and the variables can be negatively correlated, positively corelated or not correlated at all.

Relation between two events said to be causal relation, if the occurrence of the first causes the other. It means the effect of second event should be caused by the the first event.

So, causal relationship between two variables must be correlated.

For example: there is a positive correlation between the organisational behaviour and work done. if any one employee will deny to work from the group of 4 employees it will affect other employees behaviour and reduces their working ability, which will reduce tehir work done. It means that organisational behaviour between employees is the cause of less work done. so, the second event (work done) is the cause of first event (organisational behaviour) and they both are positively correlated as well.

Answer:

The four main reservoirs of oxygen cycle are terrestrial biosphere, marine biosphere, lithosphere and atmosphere.

Explanation:

Oxygen is present about 21 % in the atmosphere which comes to the earth surface i. e. terrestrial biosphere where animals and microbes use this oxygen for the process of respiration while plants are the only organisms which produces oxygen in the process of photosynthesis and this oxygen goes to the atmosphere. This atmospheric oxygen also dissolve in water which is used by the marine animals. Oxygen atom is also present with carbon atom in the form of food molecules such as glucose which is produced inn the process of photosynthesis.

The oxygen cycle is a biogeochemical cycle, in which oxygen is circulated through the lithosphere, atmosphere, rhizosphere, and biosphere. The amount of oxygen present in the Earth's atmosphere is 21%.

The oxygen's primary reservoirs are the biosphere, atmosphere, and lithosphere.

The atmosphere or the air constitutes 21% of the oxygen. The organisms present on the terrestrial surface consume oxygen via respiration.

In the biosphere, autotrophs like plants produce oxygen via photosynthesis. The oxygen is then delivered to the atmosphere, where it is again utilized by terrestrial organisms.

The oxygen when dissolved in the water is used by marine organisms in the form of dissolved oxygen.

In the lithosphere, the oxygen is circulated through chemical weathering, which the formation of iron oxides. Chemical weathering can lead to the release of oxygen in the atmosphere.

Therefore, the oxygen can be circulated through terrestrial organisms, marine animals, the lithosphere, and the atmosphere through different processes like weathering and photosynthesis.
