If a DNA molecule contains 30% cytosine, what % of the molecule should be thymine?
Answer:
20%
Explanation:
cytosine = guanine = 30%
cytosine + guanine = 60 %
adenine + thymine =100% - 60% = 40 %
thymine = 20%
If a DNA molecule contains 30% cytosine, then 20% of the molecule should be thymine.
What do you mean by DNA?DNA stands for deoxyribonucleic acid. It is considered as the genetic material of most organisms. It is a complex molecule that bears genetic information.
Amount of cytosine = 30%
According to Chargaff's rule, A=T, C=G.
∴ Guanine = 30%
Now A + T = 40%
Therefore, the amount of thymine molecules is 20%.

What does it mean if elements are in the same period
Enter text here
Answer:
--> 12.011 is the relative atomic mass number of carbon.
--> elements in the same group have the same number of electrons in their outermost shells
--> elements in the same period have the same number of electron shells.
Explanation:
An element is a pure chemical substance that contains the same type of atoms which cannot be broken down into smaller substances by any chemical reaction. Example of an element is Carbon, hydrogen, Helium, Nitrogen.
Carbon has the relative atomic mass number of 12.011 in the periodic table. This is as a result of carbon having six protons, six neurons and six electrons. Carbon being an element that has isotopes, the number of decimal seen is its relative mass compared to 1/12 the mass of one atom of carbon-12.
Periodic table shows the properties of elements that vary in a regular manner. The elements in the same GROUP have the same number of electrons in their outermost shells. Electrons are arranged in shells which forms the outermost part of an atom around the atomic nucleus. Electron are arranged in shells called K,L,M,N outward from the nucleus with maximum number 2,8,18,32 respectively. For example, atoms in group 1 include hydrogen, Lithium, Sodium and potassium. When arranged in shells, they all have the same number remaining in their outermost shell which is 1. This makes them to have similar chemical properties.
Elements in the same period have the same number of electron shells. Example of elements in the same period include sodium, magnesium, aluminium silicon, phosphorus. When their atoms are arranged in shells, they have the same number of shells irrespective of the atomic number.

During a football game, you are starting to feel cold, your body starts to shiver. What is the path of communication between your nervous system and endocrine system to help your body stay warm?
Multiple choice question.
A)
Your sensory receptors in the nervous system recognize the external change in the environment and send a signal through the somatic nervous system to your muscles and glands and tell them to start shivering.
B)
Your sensory receptors in the nervous system are blocked due to the lower temperatures so the internal receptors know that something must be wrong. It works with the endocrine system to maintain homeostasis.
C)
Your sensory receptors in the nervous system recognize the external change in the environment and immediately send a signal through the autonomic nervous system to a gland that gradually communicates your internal body temperature is also changing. Both systems work together to maintain homeostasis.
D)
Your sensory receptors in the nervous system recognize the external change in the environment and send a signal through the autonomic nervous system to your muscles and tell them to start shivering. The endocrine system is useless.
E)
Your sensory receptors in the nervous system can’t recognize the external change in the environment and rely on the endocrine system to help them know when to communicate with the muscles to shiver.
Answer:
C)
Your sensory receptors in the nervous system recognize the external change in the environment and immediately send a signal through the autonomic nervous system to a gland that gradually communicates your internal body temperature is also changing. Both systems work together to maintain homeostasis
Explanation:
The answer basically gives you an explanation, but here is mine:
The nervous system works heavily with the brain by sending signals through nerves. The endocrine system secrete chemicals for wide ranges of things, but it does this with a message that is relayed the nervous system. Since in this problem the temperature is decreasing, then the nervous system will send a message to the brain and then the message gets sent to whatever system is needed to adapt to the temperature decrease which in this case it the endocrine.

Explanation:
Deepak was lifting heavy weights for exercises. After some time he could feel cramping pains in his muscle. He took some rest and when his breathing came back to normal the pain also diminished. Describe the reason for this.
Answer:
The correct answer is - muscle soreness and overexertion.
Explanation:
When an individual does strenuous physical activity such as heavy weight lifting, muscles of the body extend and contract to support the pressure and movement.
Such weight lifting or physical activity repeatedly and for prolonged, time can overexert the muscles and muscle soreness with pain in the muscle. After resting muscle relaxed again and breathing helps in providing oxygen to muscles for aerobic respiration for more energy.

describe how more than one type of protein can be synthesized from the RNA produced from one gene
The expression of genetic information as protein is a complex process consisting of several steps. Genetic information is encoded in DNA that represents a linear sequence of nucleotides. The first step of the realization of genetic information is its storage and amplification that is controlled by replication. Replication is the process of the formation of two daughter DNA molecules based on the parent DNA molecule. Using special enzymes, the double helix of maternal DNA is decomposed into two strands, a second strand is built on each strand formed, producing two identical daughter DNA molecules, which are then twisted into separate spirals.
Two insect groups vary genetically by two genes. When put together,they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
The insects are the same species.
Explanation:A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

True or False:
Bacteria are Eukaryotes.
Answer:
Bacteria belongs to the Prokaryotes family of microorganisms.
Explanation:
The answer is false.
The given statement is False as the Bacteria are prokaryotes usually.
What are Prokaryotes?The cells falls majorly under two categories:
- Prokaryotes and
- Eukaryotes
The single celled bacteria falls under the category of Prokaryotes.
Components of Prokaryotes are:
These cells share common component with Eukaryotes such as
- Plasma Membrane which is an outer covering separating the cell's interior from its surrounding environment.
- Cytoplasm containing cellular components.
- DNA
- Ribosomes, helpful in synthesis of proteins.
A prokaryotic cells is simple, single celled organisms lacking nucleus or other membrane bound organelle.
Prokaryotic DNA is found in the central part of the cell in the darkened region called the Nucleotide.
The diameter of these cells are smaller than Eukaryotes and allows ion and organic molecules to quickly spread to other parts of the cell.
What are Eukaryotes?A eukaryotic cell has a membrane bound nucleus and other membrane bound compartments or sacs called organelles having specialized functions.
The word eukaryotes meant true kernel or true nucleus due to presence of membrane bound nucleus in these cells.
These are found in higher level organisms including plants, animals and humans.
