Which of the below is an example of a chemical that plants, algae, and animals all need to survive and grow?

What is the overall function of an enzyme?

katrin2010 [14]

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

Determine whether each example represents continental drift or sea floor spreading.

laila [671]

Answer:

Sea floor spreading-> Oceanic ridge and Magma pushing two plates apart

Continental drift-> Concept of pangaea and Oceanic plates sliding under continental crust

Explanation:

Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.

Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.

Into which chamber of the heart do the superior vena cava, inferior vena cava, and coronary sinus return deoxygenated blood? Cir

azamat

Answer:

Human heart is comprised of four regions, components, zones or muscular containers. As, the blood quality is regulated by the blood, by keeping the deoxygenated form of blood apart from the oxygenated form of blood inside the heart and then provide suffiecient amount of materials, solutes, and other nutrients to the different tissues and organs of the human body in a proper manner.

The deoxygenated form of blood is collected and brought to the right atrium by the superior and inferior venacava, as it provides a more safer route for the transportation of these materials in order to remove the unwanted substance from it by sending it back to the lungs through the pulmonary artery.

Inside the lungs the blood is cleaned up and then sent back to the heart in order to be pumped into the different portions of the heart.

Answer:

a. Cross-sectional study

Explanation:

A cross-sectional analysis includes at one particular point in time looking at data from a population. Participants are chosen based on specific variables of interest in this type of study.

For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.

Evolution is the

lina2011 [118]

Answer:

Evolution is the biological process that happens over time in a population, giving rise to new species. The theory of evolution states that all organisms alive on Earth today have a common ancestor which lived years ago.

Explanation:

Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.
