Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

Answer:

Due to suitable environment of the equator.

Explanation:

Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.

I believe that your answer is A) Speciation.

Answer:

Speciation

Explanation:

Over time, genetic variations can happen when organisms adapt to new environments, weather, etc. Like that thing with bears and how they all started out the same, but as they separated, the once that lived in the cold with snow got thicker fur (polar bears) and the ones that had access to a lot of fish became really big.

Answer:

This is the Prophase. Mitotic Prophase,

Explanation:

The process  cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called  a multiplication division because two daughter cells are  form from a single  the mother cells. Each of the daughter cells can also undergo Futher divisions.

It is the second stage fist  mitotic cells division after the first phase called Interphase.

In this stage, the nuclear membrane disappear, nucleolus disintegrate and  the nucleus disappeared  This is followed  by the constriction of the chromosome to sister chromatids.

The constricted nuclear membrane leads to the releases of the chromatids This is  followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.

other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)

Answer:

Genotype = 1CC: 2Cc: 1cc

Phenotype = 3 tongue curler : 1 non-tongue curler

Explanation:

This question involves a single gene that codes for the ability or not to curl the tongue. The ability to curl the tongue (C) is dominant to the inability to do so (c). This means that a heterozygote will be able to curl his/her tongue.

According to this question, If Eric, who is a heterozygous tongue curler (Cc) marries Brandy who is also heterozygous (Cc) i.e. Cc × Cc, the following gametes will be produced by each parent: C and c.

Using these gametes in a punnet square (see attached image), the predicted genotype of the offspring is 1CC: 2Cc: 1cc while the predicted phenotype is 3 tongue curler : 1 non-tongue curler.

Answer:

About 78% of the Earth's atmosphere is made up of "free" nitrogen (N2), produced by biological and chemical processes within the biosphere and not combined with other elements. ... One family of nitrogen compounds produced by nitrogen - fixing bacteria are called nitrates.

Explanation:

Hope this helps

Free nitrogen refers to nitrogen gas (N₂) that exists in the Earth's atmosphere as a diatomic molecule consisting of two nitrogen atoms bonded together. It is called "free" nitrogen because it is not chemically combined with other elements or atoms.

Nitrogen gas makes up approximately 78% of the Earth's atmosphere, making it the most abundant gas present. Despite its abundance, most organisms cannot directly utilize nitrogen gas in this form. This is because the bond between the two nitrogen atoms is very strong, requiring a significant amount of energy to break.

Therefore, free nitrogen refers to nitrogen gas (N₂) present in the atmosphere that is not chemically combined with other elements. It needs to undergo nitrogen fixation to be converted into usable forms before most organisms can utilize it.

There is a seed in the banana and then the seed grows into a tree and produces more banana

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

Explanation:

All of the things found in the Earth system can be categorized into four (4) main categories and these includes;

I. Land: this subsystem forms a sphere which is generally referred to as litosphere.

II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.

III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.

IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.

If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.

The one variable affects another happens in  experiments. Thus, option D is correct.

An experiment, or experimental research, is a research method in which the researcher manipulates or changes the value of one variable, (the independent variable) and measures the variable that is considered the dependent variable, in order to find how the change affects it.

The other three posible answers, observational research, survey and case study are also research methods, but the researcher can't manipulate or control any of the variables, these methods are used only to measure a specific variable.

Therefore, The one variable affects another happens in  experiments. Thus, option D is correct.

Sea anemones are one of the numerous predating animals found in the marine environment. They have cylindrical bodies whose bases are usually found attached to substrates and are therefore described as being sessile. However, a few species of sea anemones are known to be free swimmers.

Generally, sessile organisms are those that live their life attached to a substrate and, therefore, are not able to freely move about.

Answer:

True

Explanation:

This is because sea anemone polyp is permanently attached to the beneath of the base where it stay by it base called pedal foot. It sometimes glide around in order to prevent itself from predation and it uses it's tentacle to catch moving food particles around it and consume it. It belong to the group cnidaria.
