Buying a new light bulb will cost money so it is economically inefficient. Cleaning the light surface doesn't increase the light output from the lamp and switching off the bulb means no light at all, therfore the answer is none of the above.

The correct answer based on the question made in the picture is A. the heart beats abnormlly fast.

Tachycardia is a heart condition in which the heart rate increases over 100 beats per minute. This occurs when cardiac impulses do not work properly and this in the long term can cause severe problems.

There are several types of tachycardia, It is not always a problem, sometimes It can be in response to exercise or stress.

In the types of tachycardia we can find: atrial fibrillation, ventricular tachycardia, atrial flutter, supraventricular tachycardia, ventricular fibrillation.

Therefore, we can confirm that the correct answer based on the question made in the picture is A. the heart beats abnormlly fast.

So predators cannot see it as well

Explanation:

It will affect their ability to survive because...since Jellyfish bodies are transparent, that means they are less visible to predators or threats. Which will affect their way to survive because since they are less visible to predators, it gives them a better chance for survival since their predators can't see them very well. It also gives them a better chance for survival because hunters won't be able to see them well enough to catch them because they blend in with the water, which is called transparent.

Answer: Plants respire at night.

Explanation:

brainliest me

In Plants photosynthesis can only take place in the presence of sunlight during the day, respiration happens all day long, hence option c is correct.

Plants' respiration is visible at night and day, plants consume oxygen during respiration while also releasing carbon dioxide. Both photosynthesis and respiration take place during the day.

However, only respiration takes place at night, which uses oxygen. A sequence of chemical processes known as cellular respiration converts glucose into ATP, which may then be utilized as energy for a variety of bodily functions.

Glycolysis, citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.

Therefore photosynthesis takes place during the day but plants respire all the time, hence option c is correct.

Answer:

Organ 1: Stomach

Explanation:

The stomach holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a useable form. The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The large intestines are to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption have already taken place. The small intestines have three parts:  the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.

Answer:

Gene flow

Explanation:

Answer:

Gene flow is the movement of genes into or out of a population. Such movement may be due to migration of individual organisms that reproduce in their new populations, or to the movement of gametes (e.g., as a consequence of pollen transfer among plants).

Answer: the answer is C which is “the magmatic pressure decreases“

The magma rises and collects in chambers within the crust and as magma fills the chamber, pressure grows. If the pressure gets high enough  the magma can break through the crust and spew out in a volcanic eruption., but If the pressure is low, do not break the crust. Thus the correct option is C.

Magma is a molten and semi-molten rock mixture present under the surface of the Earth.

This mixture is usually made up of four parts such as a hot liquid base, called the melt,  minerals crystallized by the melt, solid rocks incorporated into the melt from the surrounding confines, and dissolved gases.

Answer:

Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. ... Other density-independent factors include hurricanes, pollutants, and seasonal climate extremes. Density-dependent limiting factors tend to be biotic—having to do with living organisms.

Explanation:

The two types of limiting factors are density-dependent factors and density-independent factors. These differ in their influence by the size of a population.

A limiting factor is a variable of a system which causes a noticeable change in the output or another measure of a type of system. These are present in a limited amount.

Limiting factors are of two types: Density-dependent factors and density-independent factors. Density-dependent factors have varying impacts according to the size of the population. Density-dependent factors include food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size. Density-independent factors include temperature, altitude, amount of sunlight, etc.
