Which surface erosion event does the most short- term damage?


Loss of topsoil from farmland.


Movement of rocks by glaciers.


Occurrence of mud slides after heavy rains.


Pollution of water sources caused by runoff.

Answers

Answer:

Occurrence of mud slides after heavy rains.

Explanation:

Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.

Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.

Hence, the correct answer is "the Occurrence of mudslides after heavy rains."

Which best describes the permeability of a membrane?
O A. The total thickness of the membrane
B. The flexibility of the membrane
C. The number of molecules in the membrane
D. The ability to allow materials to cross a membrane

Answers

Answer:

D

Explanation:

D. is correct because the membrane works like a security guard and only allows certain materails to cross the membrane. The definition of permeability is the state or quality that allows something to pass through.

Permeability is a standard of easy motion of liquid and gases through a membrane or material. They allow the transportation and exchange of gases in a cell.

The statement that best describes the permeability of a membrane is:

Option D. The ability to allow materials to cross a membrane.

This can be explained as:

Permeability is a physical property of membranes and substances that allows the other molecules to move through them.

It acts as a barrier from substances entering and exiting the cell or membrane and maintains the balance in a system.

Therefore, permeability is the allowance of materials across the membrane.

Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.

Describe the connection between glycerol, fatty acids and triglycerides.

Answers

Answer:

In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.

A manufacturing factory is accused of emitting high levels of CO2 into the ecosystem. The factory burns coal to heat steel
drums. The factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the
lake
Scientist A claims the factory is responsible. The burning of coal releases excess CO2 into the atmosphere. This excess CO2 is
transferred to all areas. The CO2 is not lost throughout the system.
Scientist B clams the factory is not responsible. The CO2 is released directly into the atmosphere, not into the lake. The CO2 is
lost into the upper layers of the atmosphere and not cycled back into the ecosystem
The model represents the cycle of carbon in the atmosphere. Which key issue illustrated in the model would best support Scientist
A's claim?
A)
The model shows a factory creating excess levels of CO2
B)
The model depicts a continuous cycle. An increased level in one area will
increase levels throughout.
The model depicts multiple cycles. The atmospheric cycle would show an
increased level of CO2
The model shows high levels of carbon in the lake. Any change to this level
will have a greater impact on the atmosphere.
D)

Answers

The key issue that must be illustrated in the model and best support Scientist A claim is as follows:

The model depicts multiple cycles. The atmospheric cycle would show an increased level of CO2.

Thus, the correct option is C.

What is an Ecosystem?

An ecosystem may be defined as a place or an area in which individuals of different species live together and interacts with one another for the purpose of food, shelter, and space.

According to Scientist A, the factory is responsible for the excess level of carbon dioxide in the atmosphere. This is absolutely true because the factory burns coal that liberated a high amount of CO2 into the environment.

Apart from this, the factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the lake. This increases the concentration of CO2 in the lake as well.

Therefore, the correct option for this question is C.

How many genes make up the human genome?
four: adenine, thymine, guanine, and cytosine
23 pairs of genes
20,000–25,000 genes
3 billion genes

Answers

Answer:

The correct answer is - 20000, 25,000 genes.

Explanation:

Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.

According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.

Thus, the correct answer is - 20000, 25,000 genes.

Genes are the hereditary units, which are present in the coded segments of the DNA. Genes carry the information from parent to daughter cells.

There are 20,000 to 25,000 genes that make up the human genome.

Human Genome Project was conducted for several years, the result obtained was:

The human genome project was an international scientific project, which aimed at determining the base pairs that make up the human DNA.

The project estimated that humans consist of 20,000 to 25,000 genes in their genome. Each individual inherits the copies of genes from both parents.

Therefore, the correct answer is Option C.

Which would have most likely stopped Mendel from finding a pattern in his results?
O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring​

Answers

Answer:

A. If seed shape did not have a clearly recessive form

Explanation:

To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.

For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.

Answer:

A. If seed shape did not have a clearly recessive form.
