Answer:

The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Answer:

The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).

Explanation:

Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.

- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.

- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.

- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.

The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Answer:

B. All of the fish, bacteria, and mammals that live in a lake

Explanation:

In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.

Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.

Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".

Explanation:

During thermotherapy, treated skin becomes warm and develops redness, or erythema, as the capillaries in the skin's deep layers fill with blood.

Answer: Black allele has frequency of 0.14.

              Red allele has frequency of 0.86.

             The frequency of heterozygotes is 0.241

Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:

[tex]p+q=1[/tex]

[tex]p^{2}+2pq+q^{2}=1[/tex]

p represents frequency of dominant allele;

q represents frequency of recessive allele;

2pq is frequency of heterozygotes;

For the frequency of red allele, which is dominant, we can use:

[tex]p^{2}=\frac{37}{13+37}[/tex]

[tex]p^{2}=\frac{37}{50}[/tex]

[tex]p^{2}=0.74[/tex]

[tex]p=\sqrt{0.74}[/tex]

p = 0.86

For the black allele:

[tex]p+q=1[/tex]

[tex]q=1-p[/tex]

[tex]q=1-0.86[/tex]

q = 0.14

Frequency of heterozygotes is

2pq = 2(0.86)(0.14)

2pq = 0.241

Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

Answer:

Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface.

Explanation:

Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Answer:

the breaking down or dissolving of rocks and minerals on the surface of the Earth is known as weathering

Answer:

C.  sharp thorns

Explanation:

The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.

Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.

Answer:

The principles used to collect, process and analyze statistical data in Agriculture is explained below in details.

Explanation:

There are multiple techniques used to collect or receive data for statistical examination. Three of the most traditional techniques are Direct Observation • Operations and • Surveys. A review petitions data from people; e.g. Gallup surveys; pre-election surveys; marketing reviews. Field data collection facilitates us to gather important information such as the crops farmed, agronomic methods utilized by the farmer, and data on the temporary growth of crops.

glaciers, rivers.wind

Answer:

Wind and water (rain) can erode rock

Erosion occurs if weathered materials such as soil and rock fragments are carried away by wind, water or ice. Many forces are involved in weathering and erosion, including both natural and man-made causes.

Answer:

Genetic = yes

Infectious = no

Potentially lethal = yes

Inherited = yes

Explanation:

"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.

It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.

Explanation:

The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.

Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.

The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.

Answer:

The function of a cell wall is to protect and support the organism.

Answer:

aluminum silicate minerals

Explanation:

Aluminum silicate minerals has the same chemical composition most similar to andalusite, sillimanite, and kyanite.

Chemical composition is defined as any substance made up of similar molecules made up of atoms from two or more chemical elements.

It can also be defined as a scientific symbol used to show the number and kind of atoms in a molecule.

Chemical composition containing basic components such as carbon, hydrogen, and oxygen which are very important for development and growth of human life.

Human body mainly consist of six important elements which help in growth and development. They are Carbon, oxygen, hydrogen, nitrogen, calcium and phosphate.

Thus, aluminum silicate minerals has the same chemical composition most similar to andalusite, sillimanite, and kyanite.

Answer:

What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.
