Answer:

The answer is B. Stratum Basale

The shoals are often more than 7 km long, 1.5 km wide and 30 metres deep and are clearly visible from spotter planes or from the surface. Sardines group together when they are threatened. This instinctual behaviour is a defence mechanism, as lone individuals are more likely to be eaten than large groups.

The shoaling habit includes all the popular, common fish that belong to the Characin family (tetras), Cyprinidae family (barbs and danios) and Melanotaeniidae family (rainbow fish). There are even some species of catfish and cichlids that shoal.

Many kinds of fish prefer to swim together in groups called shoals. ... Shoaling can help fish because there are more eyes for spotting danger from predators or for finding food. Predators also find it more difficult to target a single victim in a big, moving group.

Answer:

True

Explanation:

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.

Answer:

False.

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.

Answer:

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.

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:

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.

2. D

Explanation:

In an experiment, which aims at solving a particular problem or answering a scientific question about nature, the scientific method is employed. The scientific method contains the following steps:

- Making an observation.

- Asking a question.

- Formulating a hypothesis

- Testing the hypothesis via experimentation

- Analyzing the results

- Conclusion

According to question 1, the PURPOSE of an experiment portrays what is about to be done in a question format. For example, a purpose can go this: What will be the effect of pesticides on the growth of cowpea?. Furthermore, the PURPOSE helps make a research and state a hypothesis in the next step.

- In the analysis of result, the qualitative or quantitative approach is used. The QUANTITATIVE method involves the use of numbers or numerical data to express the outcome or result of the experiment. By counting or measuring, a numerical data is collected and given a unit depending on what is being measured

Answer:

External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs.

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.

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.

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".

Answer:

It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.
