The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.

Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.

Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.

The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.

The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see

This is exactly what the graph depicts, so option C is correct.

Answer:

The correct answer is edema.

Explanation:

When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.

However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.

Answer:

Did you know: There are over 1,400 species of bats worldwide. Bats can be found on nearly every part of the planet except in extreme deserts and polar regions. The difference in size and shape are equally impressive. Bats range in size from the Kitti’s hog-nosed bat (also called the Bumblebee Bat) that weighs less than a penny -- making it the world’s smallest mammal -- to the flying foxes, which can have a wingspan of up to 6 feet. The U.S. and Canada are home to about 45 species of bats and additional species are found in the U.S. territories in the Pacific and Caribbean.

Answer:

D

Explanation:

Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.

Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.

Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Answer:

The concept of fraction

Explanation:

What is the concept of fraction tho? Fractions are numbers that represent a part of the whole. When an object or a group of objects is divided into equal parts, then each individual part is a fraction. ... It is divided into a numerator and denominator where the denominator represents the total number of equal parts into which the whole is divided.

A fraction represents the number of parts that we take from a unit that is divided into equal parts. It is represented by two numbers separated by a fraction line.

Answer:

12 m^2

Explanation:

Area = length * width

A = 4m * 3m

A = 12 m^2

(Area is measured in square units)

Answer:

D. 12 m2

Explanation:

To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:

4 x 3 = 12.

So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

Answer:

C. Co-dominance

Explanation:

because both phenotypes are expressed fully

Answer:There are two kind of nuclear ractions: fusion and fission reactions.

Both release a huge amount of energy in different ways.

Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.

That is what model 1 shows:

Model 1: Atom 1 + Atom 2 = Atom 3 + energy

That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.

In the Sun two atoms of hydrogen fuse into a larger atom of helium.

That is represented by the nuclear reaction:

Explanation:

Prokaryotes were split into two kingdoms because they were discovered to be very different from each other.

The correct option is B.

Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.

Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

Answer:

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

Explanation:

Lysosome digest worn out cell and destroyed invading viruses and bacteria

Vacuole help to maintain water balance

Mitochondria is produced energy to cell in form of ATP

Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.

Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.

Asexual reproduction.

Explanation:

The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.

Answer:

Nitrate deficiency

Explanation:

Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
