Answer:
The correct answer is - А. experiment.
Explanation:
An experiment is a type of research method used for scientific investigation to check how a natural phenomenon works and how a particular variable affected by causing or manipulating one variable.
The affected variable called the dependent variable and the variable that is changed is called the independent variable. Other than independent variables other variables should be controlled so there would be no influence on the result other than independent varibles.
The research method in which a researcher changes the value of one
variable to determine how the change affects another variable is during
Experiments.
What is an Experiment?An Experiment is usually conducted to confirm or refute claims of an
hypothesis. This is usually carried out by using two types of variables
called:
Dependent variable.Independent variable.This involves changing the independent variable which causes a
corresponding change in the dependent variable

7. Challenge yourself: You have already learned that mutation is one source of
variation in a population. Based on what you have just seen, what is a second
source of variation?
(I just need more information or explanation) please
Answer:
Natural selection would be the other source because organisms that have a beneficial trait will live, but organisms that do not have a beneficial trait might die. So the organsims that do survive will reproduce and pass on those traits to their offspring. Eventually all the organisms that do not have a beneficial trait will die out, leaving most of the population having that beneficial trait.

Why solid melt when heated
Answer:
When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.

All animals need food, water, shelter, and space to live. which of these is difficult to find in a grassland habitat?
According to the scenario, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. It may also be characterized as the area where the basic demands of an organism are fulfilled like food, water, space, mating partner, etc.
Grasslands habitats are generally open and continuous, fairly flat areas of grass. They are often located between temperate forests at high latitudes and deserts at subtropical latitudes. In these habitats, the availability of shelter is very low because of an abundance of small grasses across the area which is insufficient to build a shelter.
Therefore, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Static frictional force is the minimum force that must be overcome for one object to slide over another.
What is frictional force?Frictional force is the force the acts between the surfaces of two objects in contact which oppose the motion of one object over the other.
The minimum force that must be overcome for one object to slide over another is known as static frictional force.
If the applied force is greater than static frictional force, the object will start moving over the other.
Therefore, static frictional force is the minimum force that must be overcome for one object to slide over another.

A different couple has a child with O type blood who has a blood disorder and
needs regular transfusions. The mother is type B, and the father is type A. A
genetic counselor created a punnett square to show them the chance of having
another child with type O blood. The results are shown below:
What is the chance of the couple producing another child with type O blood? __%
Answer:
25%
Explanation:
A simple way to think of the punnett square is to think of it as divided into fourths. Only one of these fourths has o type blood. Therefore, there is only a 1/4 or 25% chance of them having another child with o type blood. Hope this helps :)

If all the bees in the hive come from the queen, how are they related?
All the bees in the hive are cousins.
All the bees in the hive are sisters and brothers.
All the bees in the hive are aunts and uncles.
Answer:
B :D
Explanation:
I just had this question on a Gizmo lab of mine and I answered "B" and it was correct :) The answer above mine is correct :D
It's amazing to see how the bees in the hive interact with one another. All of the bees in the hive are directly descended from the queen bee, who serves as the mother of the whole colony.
What is the task of a queen in the queen bees ?The only bee in the colony with the ability to reproduce is the queen, and she does it by laying eggs. The drone bee, the queen's partner, fertilises the eggs, and the larvae that result hatch into worker bees.
Given that they all have the same mother, the worker bees are all sisters and brothers. They are all also cousins since they have the same father, the drone bee. A small number of female bees known as "daughters of the queen" are also produced by the queen bee.
Additionally, these children are sisters to the These daughters are not relatives; although they are sisters to the worker bees, they are not linked to the drone bee. The queen bee can also give birth to drones, which are male bees. These drones are not relatives since they have no siblings or brothers and no connection to worker bees.
However, because they have the same mother as the worker bees, they are aunts and uncles to the latter. In conclusion, there are many relationships among the bees in the hive. They are all related since they all have the same mother, the queen bee. They are cousins because they have the same parent, the drone bee. The worker has relatives and uncles who are drones.

Which of the following best explains how viruses replicate?
Answer:During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.
Explanation:
Virus replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before their replication can occur.
What do you mean by Viruses?Viruses may be defined as infectious microbes consisting of an element of nucleic acid surrounded by a protein coat.
There are six steps that govern the replication of a virus. They are given below:
Adsorption or attachment: This step attaches the virus particle to the plasma membrane of the host cell. Penetration: It is done by receptor-mediated endocytosis and the virus now enters into the cytoplasm of the cell.Uncoating: This step breaks the whole structure of the virus particle and allows its genetic material to reach inside the nucleus of the host cell.Viral Genome replication: This is done in the nucleus of the host cell.Maturation: It involves the growth of replicated virus particles.Release: It allows the replicated virus particle to move outside the host cell by bursting it.Therefore, it is well described above.
