Answer:

When plates move away from each other at divergent plate boundaries, interesting things happen. For example, when plates move apart, molten rock from the Earth's core ascends and forms new crust. ... This molten rock can rise up to the surface, forming a volcano, and causing volcanic eruptions.

Answer:

Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

Answer: Yes, organisms are able to transform both light energy and chemical energy into food.

Answer:

microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.

The main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.

The endoplasmic reticulum serves as the transport system of the eukaryotic cell, with many other important functions such as protein folding. It is a type of organelle made up of two subunits –

1. Rough endoplasmic reticulum (RER)

2. Smooth endoplasmic reticulum (SER)

It has a continuous nuclear envelope. The endoplasmic reticulum contains ribosomal granules anchored to the cytoplasmic surface of the cisternae is involved in the synthesis and secretion of proteins through membrane-bound vesicles called ergastoplasms.

Thus, the main function of the Rough Endoplasmic Reticulum is the production of membrane and proteins secreted by the cell.

Answer:

1. Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers and them by other consumers.

2. Producers are living things that use energy to make food. Producers make food for themselves and other living things.

3. the difference between a herbivore and an omnivore is a herbivore eats only plants or producers, and an omnivore eats both plants, and other animals/consumers.

4.A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.

Immediately, the pathogen has been recognized:

Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.

The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.

Antibodies helps to immobilize pathogen for macrophage to feed on.

if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.

Answer:

The advantages of endothermy are well known: the ability to occupy thermal niches that exclude many ectothermic vertebrates, a high degree of thermal independence from environmental temperature, high muscular power output and sustained levels of activity, to name but a few.

The major advantage of endothermy over ectothermy is decreased vulnerability to fluctuations in external temperature. Regardless of location (and hence external temperature), endothermy maintains a constant core temperature for optimum enzyme activity.

3-disturbing a drop of water such that it breaks into smaller droplets

4-popping a bag of popcorn

5-The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

Hope this helps! Good Luck!

A nuclear chain reaction happens when a single nuclear event averages out one or more further nuclear reactions, opening the door for a potentially endless chain of similar processes. Therefore, option (A) is correct.

A nuclear chain reaction happens when the output of one nuclear reaction triggers the occurrence of further nuclear reactions. These cascade reactions are nearly invariably a succession of neutron-excessive fission events. The moniker "chain reaction" comes from the fact that these extra neutrons have the potential to trigger more fission events. The functioning of nuclear power plants depends on nuclear chain reactions.

About a million times more energy is released during nuclear reactions than during chemical ones. Every fission event must result in precisely one additional fission event in order for a nuclear chain reaction to continue.

Therefore, option (A)  correctly describes the nuclear reaction.

Answer:The speed of the water flowing downhill will be affected by the degree of incline, and any structures or topographical features in its path. The faster the water flows, the more erosion occurs. Water flowing downhill moves and deposits sand at the bottom of the river. The faster the water flows, the more sand will be deposited at the bottom. A delta at the mouth of a river forms in the same way. Although the formation of the “rivers” in this activity appeared very quickly, in reality rivers can take millions to billions of years to form a path from land to sea.
