Answer: FALSE
Explanation:
The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.
Parts of the nervous system includes:
--> Central Nervous System ( consists of the brain and spinal cord)
--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).
The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE
A man who has cystic fibrosis married a healthy women. They produce 2 children who both have cystic fiber. What are the genotypes of the man and women? (use symbols to represent the alleles and which parent is which)
Answer:
The correct answer would be -
Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
Explanation:
Cystic fibrosis is a recessive genetic disease that means it exhibits only if both copies of the gene mutated, If there is only one copy of the gene is mutated the person will be healthy however, he or she will be a carrier of the mutated gene.
Given: Father has cystic fibrosis which means he has two copies of the mutated gene - cc (c - recessive)
Female - she is healthy now there is two conditions possible
1. if the mother is healthy - CC (normal allele)
C C
c Cc Cc
c Cc Cc
All offspring are in the heterozygous condition that means they are healthy carriers which is not given in the question so women must be a carrier
2. Carrier mother - Cc
C c
c Cc cc
c Cc cc
Here 50% chances of having children with CF so it is possible as two offsprings have CF according to question
Thus, Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz
What is true about cellular respiration?
Answer:
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

How are precipitation and temperature different between the polar and tropical climate zones?
Answer:
The temperature is colder in the polar climate zones. Also, there is less precipitation in polar climate zones. Meanwhile,the temperature is warmer in the tropical climate zones. Also, there is more precipitation in tropical climate zones.
Explanation:
The earth is extremely diverse in its ecosystem. Different regions are called climate biomes to understand patterns of meteorology, biology, and natural phenomena.
The biggest difference between tropical and polar climates is the difference in temperature. The tropical climate is close to the equator and has more sun all year round than anywhere else on the planet, but the polar climate is the furthest from the equator and has the least sunlight and heat of any part of the world. This makes winters harsher and summers shorter in polar climates, but hotter virtually every day in tropical climates. Both climates are reminiscent of precipitation (such as tropical rains and polar snow), but both can be quite dry. Antarctica is said to be the largest desert in the world because there is little snow falling towards the center of the continent.
What are examples of tropical desserts?Tropical deserts, such as the Namib Desert in Africa, are so hot and dry that it is difficult to survive.
Thus it concludes that precipitation and temperature are different between the polar and tropical climate zones.

Choose the mutation that you think is causing Lucy’s ADA enzyme not to work.
Form a hypothesis and explain your answer.
You can revise your hypothesis as you perform more experiments.
Answer:
Stop Codon Mutation
The mutation that I think that is causing Lucy's ADA enzyme to not work is stop codon mutation. I think so because the stop codon mutation shortens the amino acid sequence causing Lucy to have a lower amount than normal.
Explanation:
I just did it
The mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.
What do you mean by Mutation?
The sudden, stable, and inheritable changes in the genetic material of an individual, are known as Mutation.
A nonsense mutation or stop codon mutations end the process of protein synthesis. Because these codons do not code for any amino acids. Thus, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence.
Therefore, the mutation that causes Lucy's ADA enzyme not to work is a nonsense mutation.

1. Other than having many features in common, state other characteristics of species 2. Give reasons for the loss of energy from one trophic level to the next in a food chain.
Answer:
As a metabolic heat.
Explanation:
The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.
Minerals are rarely used in everyday life true or false
Answer: False
Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)
Jacob a 40 year old man who is 6 foot tall and weighs 225 pounds has been diagnosed with atherosclerosis. What healthcare plan would you design for this patient? prescribe a medication to reduce bad cholesterol and no other changes need to be made. patient is just slightly overweight and she is worrying to much about his health, therefore no change. patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds prescribe a medication that lowers blood pressure and no other changes need to be made.
Answer:
The patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds.
Explanation:
We know that the patient weighs 225 pounds, and his height is 6 feet. With this information, we can determine his Body Mass Index (BMI) using the formula:
BMI= weight/(height)²
BMI= 225/(6)²
BMI= 30.5
Once that we calculated his BMI, we compare the result with the reference chart, here we can see that for his height. he is obese. This coincides with the fact that he has been diagnosed with atherosclerosis. His body has been placing the extra fat in the arteries.
The best plan for Jabob would be to make a lifestyle change to healthier foods and an exercise plan that helps him to lose weight so that his BMI would be approximately 25 and his weight of 195 pounds. Also, this plan will reduce cholesterol levels.

Which animals should not be vaccinated?
Answer:
Every dog and cat should be appropriately immunised, and each individual animal should be vaccinated as frequently as considered necessary by their veterinarian to provide protection. The vaccination protocol to be followed and the vaccines to be used should be determined within a veterinarian–client–patient relationship. The decision should be determined by factors such as the individual animal’s health status, the animal’s age and likely effects of maternally derived antibodies (MDA), the particular disease and environmental risks to the animal, and the duration of immunity (DOI) of available vaccines.
