5. Neurons have long projections to transmit impulses. What is the name of these projections? Answer:
Answer:
Their name is "Axon"
Explanation:
An axon is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.
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.
Which of the atoms below has the lowest atomic mass?
Answer:
C
Explanation:
The atom B will have the lowest atomic mass as it has the lowest number of protons and neutrons.
What is atomic mass?Atomic mass is the amount of matter that makes up an element's atom. It is written as a multiple of 1.992646547 × 10^23 gramme, or one-twelfth of the mass of the carbon-12 atom, which is given an atomic mass of 12 units. In this scale, 1.660539040 × 10^-24 gramme is equal to 1 atomic mass unit (AMU). In honour of the English chemist John Dalton, the atomic mass unit is often known as the dalton (Da).
The total mass of the protons, neutrons, as well as electrons that make up an atom, is a little bit less than the observable atomic mass. According to an equation where the energy (E) generated equals the product of the mass (m) expended and the square of the light velocity in vacuum (c), or E = mc^2, the discrepancy, known as the mass defect, is compensated for during the combination of these particles.
Therefore the correct option is B.

Some engineers are creating models of several unicellular organisms. What would all the models have in common?
Answer:
They would all have one cell with smaller parts to do different jobs within the cell.
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.
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%.

Why do invasive species often cause a decrease in biodiversity?
Invasive species are nearly always top predators.
Invasive species produce offspring with native species.
Invasive species compete for resources with native species.
Invasive species have higher mutation rates than native species.
Answer:
Invasive species compete for resources with native species.
Explanation:
The main problem is that they change the food web.
Answer:
I think its invasive species compete for resources with native species.
Explanation:
Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

Answer:
c) The mother cell gives rise to two daughter cells with half the number of chromosomes.
Explanation:
Mitosis is a type of cell division in which a parent cell is divided into two daughter cells having diploid i. e. double number of chromosomes. This type of cell division occurs in the somatic or body cells which is responsible for the growth of that organisms. This mitosis cell division has six phases such as prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. Both daughter cells are identical to parent cell.

Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.
Explanation:
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.
