Explanation:
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.
Answer:
C. Determine how to manufacture the new heart valve.
I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.
The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.
What is meant by a Prototype?A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.
A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.
Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.
Therefore, the correct option for this question is C.

Mt. Pinatubo, a volcano in the Philippines, erupted in 1991. The eruption resulted in the cooling of Earth's surface
for two years.
What can you deduce from the information given?
O Solar energy seeped through the atmosphere,
O The eruption caused sunspot activity to increase.
O The volcano released a lot of sulfur dioxide and ash,
O Greenhouse gases caused the cooling of Earth's surface.
Answer: this is easy, i think
Explanation:
The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

PLEASE HELP!! in the process of translation, the ribosome is the site where---
a. free floating amino acids are picked up by tRNA
b. information from DNA is copied to RNA
c. DNA strands are separated and copied
d. amino acid chains are assembled from information in the mRNA
Answer:
d. amino acid chains are assembled from information in the mRNA
Explanation:
The ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).
During gene transcription, a sequence of DNA called gene is used as a template to create a messenger RNA (mRNA).Subsequently, this mRNA travels to the ribosome to be used as a template for the creation of a protein by the process of translation.The ribosome is the site where successive amino acids are added to the growing polypeptide according to the order of triplets of nucleotides or 'codons' in the mRNA sequence.In conclusion, the ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).

A) chromosome are made of DNA.
B) there are 26 pairs of chromosomes in humans.
C) alleles are the different forms of a gene that can exist.
D)chromosomes contain genes that control the inheritance of traits.
E)genes are made of chromosomes and contain all of the genetic information for an organism.
D)chromosomes contain genes that control the inheritance of traits.
The statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).
Chromosomes are linear fragments of DNA that contain part of the genetic material in eukaryotic organisms.
Alleles are different gene variants. In diploid (2n) organisms, one allele for a given gene locus is inherited from the mother, whereas one allele of the same gene is inherited from the father.
Genes contain the instructions that are inherited across generations in order to synthesize proteins (both structural and enzymatic proteins), which largely determine the phenotypic traits of an organism.
In conclusion, the statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).

Make a list of different weather patterns
Weather comes in all different forms, and it changes by the day. It could be sunny one day and raining the next. It could even be sunny, rainy, cloudy, and stormy in one day.
Common Types of Weather Elements
The weather has a lot of different factors. When someone asks how the weather is today, you need to think about temperature, humidity, precipitation, wind, cloudiness, and atmospheric pressure. All these different parts work together to create the weather you see when you walk out the door.
Like most plants, a bluebonnet begins as a seed under a blanket. When the time is right, the outer coat of the seed cracks to releaseee a tiny root tip. As the root tip begins to grow downward, the stem will begin to grow and push upward. How does the bluebonnet root knwo which way is down? How does the stem know whch way to stretch to reach sunlight? The answer is geotropism. This property of plants allows them to orient their growth with the direction of gravity. What phrase helps you determine what orient means? a. Property of plants b. To reach the sunlight c. How does the stem know d. With the direction of gravity
Answer:
d. With the direction of gravity
Explanation:
Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants. The roots show positive gravitropism and the stem negative gravitropism this they appear to be bend upside on a hill or slope. Can be seen with a potted plant, was the woody stems are capable of bending.What is the volume of a 13.4 g silver coin?

Why does it rain more heavily on the windward side of mountain ranges?
A.Air masses absorb moisture as they increase in altitude, form clouds which precipitate rain.
B.Cool air on the lee side of the mountain encounters warm moist air from the windward side causing it to give up moisture.
C.Prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing rain.
D.Cool, moist air from the oceans warms over land and precipitates rain on the windward side of mountain ranges.
It rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.
What are the prevailing winds?This is a type of wind that blows in a specific direction over a certain area, and its strength can be influenced by many factors, like the elevation of the land, temperature and pressure differences between air masses, earth rotation, etc. In a mountain range, the prevailing winds carry moist air to the top of the slope, where it cools and releases precipitation, that causes the rain.
Hence, it rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.
