O A. Elements are pure substances, but compounds are not
B. Compounds can be broken down by physical changes, but elements cannot.
C.
Elements are made of identical atoms, whereas compounds are made of
identical molecules,
D. A compound contains many different kinds of elements, whereas an element
contains many different kinds of atoms.​

Answers

Answer 1

Answer:

C.  Elements are made of identical atoms, whereas compounds are made of  identical molecules.

Explanation:

Elements are made of identical atoms, whereas compounds are made of  identical molecules because elements are made of atoms of only one kind while on the other hand, compounds are the pure substance that is made of molecules that is similar as well as different from one another. Both element and compound are pure substance. Compound can be broken down by chemical means whereas elements can not be broken down.

Which type of rock is shown in each of these photographs?

Answers

Let us see the choices

In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.

Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.

Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.

Answers

Answer:

Yes, it is all of the above.

Explanation:

Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

What do you mean asexual reproduction?

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.

The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

A woman bought 10 crates of eggs from the market. On getting home, she realized that 15 eggs were broken. What is the ratio of broken eggs to unbroken eggs.

Answers

Answer:

B:U = 1:20

Explanation:

Let the number of broken eggs be B.

Let the number of unbroken eggs be U.

Given the following data;

Number of crates of egg = 10 crates

But, 1 crate of egg = 30 eggs

10 crates of egg = 30 * 10 = 300 eggs

B = 15 eggs

U = 300 eggs

Ratio B to U = B:U

B:U = 15:300

Dividing by 15, we have;

B:U = 1:20

B, the discovery of new evidence resulted in changes to the cell theory,

The statement 'the discovery of new evidence resulted in changes to the cell theory'  best summarizes why the cell theory was developed over time.

The cell theory is a model in cellular biology that states all cells evolved from a pre-existing cell.

This theory also states that all organisms are composed of cells.

The cell theory was further modified as new evidence emerged in the scientific community.

In conclusion, the statement 'the discovery of new evidence resulted in changes to the cell theory'  best summarizes why the cell theory was developed over time.

Answers

I'm a bit confused about this question. But I will try my best to answer. :)

To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.

I hope this helps! :)

A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.

What is the Immune response?

The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.

A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.  

Carrier molecules typically do not elicit an immune response by themselves.

Therefore, it is well described above.

The United States is often called the "melting pot" because people from all nations have made a home here. If someone has a grandmother from Brazil, for example, that came to live in the US, would relocating to Chicago change her grandkids’ skin tone phenotype? Why or why not?

Answers

Answer:

Technically no

Explanation:

Technically no. The skin tone of the individual is caused by two factors, one is genetic and the other is environmental. The genetic factor will continue being there since the grandkids would be descendants of the grandmother. The environmental factor can change skin tone phenotype over the course of an individual's life. Although in this scenario, both locations have the same type of weather. Both Brazil and California are incredibly hot locations all year round.

write any three methods of controlling flood landslide and soil erosion​

Answers

You can reduce soil erosion by:
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Floods can be controlled by redirecting excess water to purpose-built canals or floodways, which in turn divert the water to temporary holding ponds or other bodies of water where there is a lower risk or impact to flooding.

modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.
