Answer:

A

Explanation:

The correct answer would laboratory experiment.

In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.

Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.

The correct option is, therefore, A.

Answer:

S. carcini is a parasitic barnacle species

Explanation:

Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.

Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.

By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.

Answer:

More negative E value means More likely to accept electrons.

More Positive E value means More likely to donate electrons.

Compounds on the right side of the slash are the reduced form of the compound.

Compounds on the left side of the slash are the oxidized form of the compound.

Explanation:

Redox tower is formed by reduction oxidation reaction which transfer of electrons happen between two species. It is a chemical reaction in which oxidation number of ions changes due to gain or loss of electron.

Redox reactions involves loss/gain of electrons.

A redox reaction equation is one in which a chemical specie either donates or accepts electrons. If the value of E is negative, the specie most likely donates electrons while a positive E shows that the specie readily accepts electrons.

The compound on the left side of the slash is oxidized while the one on the right side of the slash is reduced.

Answer:

Acetyl CoA; glucose

Explanation:

Acetyl-CoA is a molecule known to be part of different reactions during carbohydrate, protein, and lipid metabolism. Pyruvate (also known as pyruvic acid) is a molecule whose decarboxylation produces acetyl-CoA. Glucose cannot be synthesized when amino acids are converted to Acetyl CoA because this molecule (Acetyl CoA) cannot be converted back to pyruvate. The citric acid cycle (CAC), also known as the tricarboxylic acid (TCA) cycle, is a group of biochemical reactions that release energy by oxidation of acetyl-CoA obtained from sources such as proteins, carbohydrates and fats. During amino acid metabolism, glucogenic amino acids and TCA intermediates can be converted into glucose through gluconeogenesis.

Answer:

A. near-Earth objects.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.

A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.

Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.

Hence, near-Earth objects may pose a collision danger to planet earth.

DNA has instruction in it on how to do protein synthesis.

Answer:

Due to their broad surface areas, green leaves can absorb more sunlight at a given time, and due to the thinness of the leaves, the light energy can easily penetrate the leaf surface and be trapped by the chloroplasts. This makes photosynthesis efficient. Therefore, green leaves are thin and broad.

A hematopathologist is a health care professional who works with the unicellular or multicellular organisms, both equally. Thus, the correct option will be B.

Hematopathologists can be referred to as the specially trained healthcare professionals who are responsible for the diagnosis of the diseases related to the different types of blood cells.

Hematopathologists use the specialized tests such as flow cytometry studies and the immunohistochemistry. The hematopathologist uses the results of these tests for the analysis and diagnosis of the infections and diseases of the blood, lymph nodes and the bone marrow.

A hematopathologist works with both the unicellular and multicellular organism equally.

Answer:

The field of genetics involves the study of genes, segments of DNA that code for specific traits, behaviors, or other characteristics of organisms. ... By studying genetics and DNA, we can get the best idea of how species are related to each other, and therefore how to classify them.

The field of genetics involves the use of DNA in the process of classifying organisms.

Genetics is the scientific study of genes and heredity and how certain characteristics are handed down from parents to offspring as a response to changes in DNA sequence.

A gene is a segment of DNA that contains instructions for constructing one or more molecules that aid in the functioning of the body.

Thus, the field of genetics involves the use of DNA in the process of classifying organisms.

Answer:

If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.

Explanation:

The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.

Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.

The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.

The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.

Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.
