How many times more erosion occurs in a soil with 3% moisture than a soil with 7% moisture is a 15 m s-1 wind?
Answer:
Twice.
Explanation:
If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

How does natural selection lead to an increase or decreased in heritable traits over time in a population?
Answer:
Not a copy and paste answer
Explanation:
When resources are limited in an habitat, organisms with heritable traits favor more survival and reproduction will tend to leave more offspring then other organisms only because of their heritable traits.

Anatomy
Label each of the following structures or processes.
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.

How is the brain involved with the senses and what is the relationship to the wat a personreacts to objects?
Answer:
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.
Explanation:
The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.
The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.
The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.
Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

Chemical Weathering 5 facts about it
Answer:
5 Facts
Explanation:
1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.
3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.
4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.
5. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.

The sugars of a DNA and RNA molecule are alternated with in the backbone of the strand
Answer:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

If you drink a gallon or more of fresh water at a single sitting, what happens to your blood and then what might happen to the cells in the blood?
Answer:
I hope this will help
Explanation:
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Hyponatremia is a low sodium concentration in the blood. It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. Symptoms can be absent, mild or severe. Mild symptoms include a decreased ability to think, headaches, nausea, and poor balance.
