Which of the following prevents blood from flowing backward through the circulatory system?
netineya [11]

Answer: Valves in the veins

Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.

The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.

Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.

Some types of fish can generate an electric field around their body to communicate with other individuals of the same species (l
Neporo4naja [7]

Answer:

Animal behaviour is controlled by the physiological mechanism

Explanation:

There are the known species of fish which communicate with each other through electrical signals or in the form of the electric field. This is known as the electrocommunication and the electroreception.

The communication between two fishes through the electric field is controlled by the physiological mechanism present in the fish and shows that the fish behaviour is controlled by the physiological mechanisms of the fish.

Thus, Animal behaviour is controlled by the physiological mechanism is correct.

Which diagrams shows reaction pathway that absorbs energy?
postnew [5]

Question:

<em>The diagram shows the potential energy changes for a reaction pathway.</em>

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Answer:

Part 1: The diagram illustrates an endothermic  reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.

Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.

The right answer is Child abuse.


Cannabis (marijuana) during pregnancy is dangerous for the fetus

During pregnancy, the active component of cannabis, which is THC (tetrahydrocannabinol), can go into the placenta and affect the fetus, including its birth weight (like the case in the question here) and brain function, reducing the baby's IQ and attention capacity.


Depending on the type of drug and the quantity consumed, it is also possible that the baby suffers from weaning at birth, that is to say from deprivation (inconsolable crying, irritability, tremors, feeding difficulties, etc.). .


Cannabis may also have longer-term effects in children (learning disabilities, behavioral problems, hyperactivity, etc.).
