bromomethane, ch₃br, is a very useful fumigant against a wide range of agricultural pests, from insects to the verticillium wilt fungus. draw the lewis structure of ch₃br.
We must take into account the number of valence electrons that each atom in this molecule has in order to design the lewiS structure for CH three br.
When we examine our setup. As a result, hydrogen will each have one valence electron while carbon will have four. So, multiplying three by one, bro mean will have seven. We therefore get at 14 when we consider the entire number of electrons accessible. Drawing single bonds to each atom around the core molecule, in this case the carbon, is the first thing we do.
And keep in mind that every bond you draw involves sharing two electrons. I have therefore used up eight of the 14 electrons I had accessible as of the moment I drew this.

Darwin's experiments are just one way to study phototropism. A student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty-five-degree angle to another, and at a ninety‐degree angle from the third.
a. What is her independent variable?
b. What is a hypothesis she might write for her experiment?
Answer:
The independent variable is what is being changed or altered in the experiment (light position), the dependant variable is what is altered or changed by the independent variable (plant).
Explanation:
Consider what is being changed in this experiment to investigate the effects? The plant itself is not changed by the experiment but the positioning of the light source is. That is your independent variable.
The Hypothesis she will write
Researchers come up with their hypothesis based on the information they already know. So to write your hypothesis think about what you already know about phototropism. What do you think will happen to the plant in relation to the positioning of the lamp? Will the plant not move? Will it bend or move to face the lamp?

7. cytosine can be mutated through a deamination reaction. after one round of replication resulting in double stranded dna, what base pair would occupy this position? after two rounds of replication what base pair(s) would you expect?
cytosine can be mutated through a deamination reaction. after one round of replication resulting in double stranded DNA, uracil-adenine base pair would occupy this position. After two rounds of replication Adenine-uracil and uracil-adenine base pairs are formed in two distinct new double stranded DNA.
What is mutation?
A mutation is a change that takes place in the sequence of our DNA as a result of errors made during DNA replication or environmental influences like UV light and cigarette smoke. Viral infection, exposure to mutagens, and mistakes in DNA replication during cell division can all result in mutations. Germline mutations, which occur in eggs and sperm as opposed to somatic mutations, which occur in body cells, can be passed on to progeny.
A cytosine base can be transformed into uracil, a base generally only found in RNA, by a chemical process called deamination. Uncorrected cytosine-to-uracil changes might result in mutations because during DNA replication, uracil will link with adenine rather than guanine (as it would if the base was still cytosine). And after two round of replication one new double strand DNA have adenine-uracil base pair and another strand have uracil-adenine base pair.
Hence cytosine can be mutated through a deamination reaction. after one round of replication resulting in double stranded DNA, uracil-adenine base pair would occupy this position. After two rounds of replication Adenine-uracil and uracil-adenine base pairs are formed in two distinct new double stranded DNA

In this scenario best described is Wolves were exposed to too many limiting factors.
What exactly causes rabies?The rabies virus is just what causes a rabies infection. The virus spreads through the saliva of affected animals. Infected animals can spread the virus to certain other animals or people by biting them. In rare cases, rabies can be spread when contaminated saliva gets in touch with an open sore or mucous membrane, like the mouth or eyes.
Why can't rabies be cured?The permeability of the barrier may increase in an infected brain, allowing antibodies and immune cells to flow through to help eradicate the infection. However, when the rabies virus is present, the blood brain barrier shuts down, thereby making it impossible for anything—including antiviral medications—to get through.

The other component is the peripheral nervous system, which is made up of nerves that connect the brain and spinal cord to the rest of the body. The other component is the peripheral nervous system, which is made up of nerves that connect the brain and spinal cord to the rest of the body.
The central nervous system is the body's processing hub. The majority of bodily processes, including awareness, movement, thought, speech, and the five senses of sight, hearing, emotion, taste, and smell, are controlled by the brain.
The central nervous system (CNS) contains motor neurons in the spinal cord, which communicate with muscles, glands, and organs all over the body. All of our muscular movements are thus directly controlled by these neurons, which send impulses from the spinal cord to skeletal and smooth muscles (like those in your stomach). In reality, there are two different kinds of motor neurons: lower motor neurons, which travel from the spinal cord to muscles, and upper motor neurons, which travel from the brain to the spinal cord.
Hence a(n) motor neuron carries information from the central nervous system (CNS) to skeletal muscle in the periphery.
