Answer: products

Explanation:

The substances bfore the chemical reaction are actually called reactants. Substances that are there after the chemical reaction are products. Hope this helps!

Answer:reactants

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.

Answer: D Endoplasmic reticulum (ER)

Explanation: It moves proteins throughout the cell

The control group is the main one because it acts as a benchmark to balance the results of the experiment.

Control groups are a principal aspect of true experimental designs. The presence of control groups authorizes researchers to confirm that study results are due to the drafts of independent variables rather than irrelevant variables. The control group of an experiment is a group that is not revealed to the independent variable and thus serves as a benchmark to which to compare the outcome of the experimental group. An experimental group, also known as a use of group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be similar in all other ways.

So we can conclude that an example of a control group is a group of individuals in a detached trial that receive placebo pills instead of medication.

Answer:

When the concentration of molecules of a substance is the same on both sides of a membrane the solution is isotonic.

Explanation:

A given substance, when it has the same concentration on both sides of the membrane, is in equilibrium and the solution is called isotonic, from the extracellular space with respect to the cytoplasm.

The cell membrane is semipermeable to the passage of water and some substances. Hypertonic and hypotonic solutions tend to establish the dynamics of entry and exit of molecules or water, due to the concentration or osmotic gradients that are established, respectively.

An isotonic solution does not generate gradients, because the concentration of molecules is equal in the extracellular space with respect to the intracellular space.

Microscope where “micro” means small and scope is like a tool to see thing and salt crystals are small so be choice is microscope

A microscope is which produces large images of tiny  substance and provide observer a close view of minute structures at a convenient scale for examination and analysis.

Anatomically the microscope consist of  three structural parts, i.e. head, base, and arm, where head is known as the body and it carries the optical parts in the upper part of the microscope.

Base of microscope is used to support  and carries microscopic illuminators and Arms connect the base and the head and the eyepiece tube to the microscope base.

The optical parts are basically applied for the  view, magnify, and production of an image from a specimen placed and the various parts.

Eyepiece or ocular located at the top of the microscope with standard magnification is 10X, Eyepiece Tube which carries the eyepiece just above the objective lens.

Answer:  

the water begins to sink to the bottom of the glass.  The colored water behaves this way because of convection currents. As the warm air rises, a pattern of air movement is formed called a convection current. We can see this in air and in water.  The process is convection current.

Explanation:

Convection is one of three main types of heat transfer. The other two being radiation and conduction. Convection is the transfer of heat by the movement of heated particles into an area of cooler particles. You can experience convection when you light a match. The air directly above the lit match is always hotter than the air around the match.

This difference in temperature around the match is caused by effect of heat on the density of air. Hot air is less dense than cool air and will rise leaving the cooler air below. As the warm air rises, a pattern of air movement is formed called a convection current. We can see these convection currents in air and in water.

Convection currents in the atmosphere affect our weather. The rising of warm air and falling of dense cool air causes our winds. When warm, moist air rises and mixes with cold air, the atmosphere becomes unstable. This causes thunderstorms.

The Gulf Stream off the eastern coast of the States is a convection current. It carries warm water from the tropics up the east coast north toward the cold arctic waters.

 Heat affects the density of water as well. You can create your own convection current with water that will allow you to see the currents caused by the density difference of water at different temperatures.

The warm water will melt the ice cube, but the resulting water will be very cold. This cold, dense water will sink to the bottom of the glass. You can see this happening because the melted water from the ice cube will be whatever color you made your ice cube.

As the water warms, it will rise back to the top of the glass. The colored water will allow you to see the convection current in the glass.

Answer:

Daughters who are descendants of a woman carrier of Fragile X Syndrome and a healthy man will have a 50% chance of having or being carriers of the syndrome.

Explanation:

Fragile X syndrome has an autosomal dominant inheritance pattern, linked to the X chromosome. That is, someone with an altered X chromosome can either be a carrier or have the syndrome.

In this case, the mother is a carrier of the altered chromosome (X) while the father is neither a carrier nor has the condition (XY).

Cross X x XY

Alleles         X           Y

[tex]X^{f}[/tex]            [tex]X^{f}[/tex]X       [tex]X^{f}[/tex]Y

X               XX          XY

The couple has a 50% chance of having daughters, and of those daughters half (50%) have the chance of having an Xf chromosome, and being a carrier or suffering from the syndrome.

Answer:

The community will slowly decline, or be just fine, or be better off.

Explanation:

Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.

If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).

And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

Answer:

Sudden reversal of the electrical charge across the membrane of resting neuron

Answer:

Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

Answer:

First law: In the ecosystem, the energy flow from lower levels of the food chain to the highest levels

Second law: During energy transference between trophic levels, the main part of the energy is lost as heat and other processes.

Explanation:

The first law of thermodynamics states that the energy can not be created or destroyed, but instead it is transformed into one type to another. Moreover, the second law states that when energy is transformed an important proportion of this energy is lost as heat, and it increases the entropy level.

In an ecosystem, the energy flow is unidirectional, it means that energy flow from primary producers to primary consumers, then from primary consumers to secondary consumers and so successively in all levels. Moreover, organisms fight against entropy by converting foods into energy (which is used to maintain order within their cells. During the feeding process, the energy intake is not 100 % efficient, it means that most part of the energy is lost as heat (approximately 90%), thereby increasing the entropy in the ecosystem.
