Solution:

Remember that viruses that infect bacteria are called bacteriophages. In effect, bacteriophages inject DNA into the host cell, while animal viruses enter by endocytosis or membrane fusion.

The differences between bacteriophages and animal viruses can be detailed in the comparison of their Multiplication Cycles:

Attachment:

For bacteriophages, tail fibers attach to cell wall proteins. Whereas, in animal viruses, the attachment sites are plasma membrane proteins and glycoproteins.

Penetration:

In bacteriophages, Viral DNA is injected into the host cell. Whereas, in animal viruses, the capsid enters by endocytosis or fusion.

Uncoating:

It is not required in bacteriophages. Whereas, in animal viruses, there is enzymatic removal of capsid proteins.

Biosynthesis:

In bacteriophages, this occurs in the cytoplasm. Whereas, in animal viruses, this process occurs in the nucleus (DNA viruses) or cytoplasm (RNA viruses).

Chronic infection:

In bacteriophages, lysogeny is generated. Whereas, in animal viruses, there is a latency or slow viral infections.

Release:

In bacteriophages, the host cell is lysed. Whereas, in animal viruses, nonenveloped viruses rupture the plasma membrane.

Answer:

The correct answer is B. False

Explanation:

The genotype of an organism determines its phenotype. Phenotype is constituted by observable characteristics of an organism. These characteristics are codified by genes, and the combination of the differents variants of a gene which codify a phenotipic characteristic constitutes the genotype. For example: eyes color is a characteristic. Its is codified by variants of a gene. The combination of two variants of a gene gives a genotype, which codifies for the phenotype 'blue eyes'.

Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.

Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.

Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.

Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.

The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.

The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.

Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.

This shows that Carlton has an impaired absolute threshold.

He could not detect the smallest quantity of a stimulus to differentiate between the smells.

Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.

This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.

Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

If we can genetically engineer any species of organism, it would be a human-fish hybrid.

A human-fish hybrid would have lungs as well as gills to breathe so that life can be also possible under water.

It would be revolutionary because humans would not be just restricted to land but also be able to explore deep seas and oceans and found new types of minerals and other hidden treasures in the deep seas and oceans.

If somehow land became unfertile or flood hits, human will still be able to cope up with that and if by some reason the land collapses or air became all polluted, we can still live underwater and make a new civilization.

This hybrid will also provide us the power of echolocation because of the sonar detection feature in most fishes.

This hybrid would also be able to talk to other fishes if fishes can talk to each other, it will basically be like a living mermaid just not the fin.

People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might get flu by touching a surface or object that has flu virus on it and then touching their own mouth, nose, or possibly their eyes.

High salt concentrations in soil is plants that appear dehydrated even when they are receiving adequate water because the salts comes from the irrigation activity.

The more salt that accumulates in the soil from irrigation and natural occurrence in the soil. We applied water to the plants in order to maintain the water content in the plants and make them hydrated. Sometimes the water has high salt concentration that negatively affected plant growth. Salinity greatly affects production in crops and trees by preventing the nitrogen uptake, reducing the growth and also stop the reproduction process in plant. Chloride salts are the toxic ion to plants. When its concentration increases in the soil, the plant is poisoned and dies in the end.

So we can conclude that High salt concentrations in soil is plants that appear dehydrated even when they are receiving adequate water because the salts comes from the irrigation activity.

if growth hormone is secreted into the blood in high amounts after the epiphyseal plates close,the result is acromegaly

Acromegaly develops if growth hormone is produced into the blood in large levels after the epiphyseal plates complete.

The anterior pituitary gland produces growth hormone, which is then released into the blood. In addition to producing growth hormone, the pituitary gland also makes other hormones with distinct purposes.

Children's growth is aided by growth hormone, which affects many different body components. Growth hormone does not increase height after the fusion of the epiphyses, the growth plates in the bones. Although it does not promote development in adults, it does assist in maintaining a healthy body composition and metabolism, including assisting in regulating blood sugar levels.

Teresa is likely to be a carrier of the Huntington's disease allele, but not affected by the disease herself, since she inherited one dominant allele A and one recessive allele B.

Teresa's genotype is Aa, where A is the dominant allele that causes the production of the protein Huntington in a way that leads to Huntington's disease, and a is the recessive allele that does not cause the disease. However, since Teresa inherited one allele A and one allele B, she is not affected by the disease herself because the dominant allele A is not present in two copies.

Instead, she is a carrier of the disease-causing allele A, meaning that she has the potential to pass it on to her offspring. If she has children with someone who also carries the A allele or has Huntington's disease, there is a possibility that their children may inherit two copies of the A allele and develop Huntington's disease.

This question is incomplete, the complete question is as follows:

A cell biologist measures the volume of a bacteria cell. The volume is 6.741*10^-10 L. What is the volume in picoliters? Write your answer as a decimal.

The answer is 674.1 picolitres (pL)

Explanation:

According to the question, the volume of a bacterial cell is measured by a cell biologist to be 6.741*10^-10 L i.e. 0.0000000006741L (expanded form)

The volume in picolitres and Litres are interconvertible.

1 × 10^12 picolitres = 1L

Hence, 6.741 × 10^-10 L will be 6.741 × 10^-10 × 10^12 pL

= 6.741 × 10^ (12-10)

= 6.741 × 10^ (2)

= 6.741 × 10^2

= 674.1

Hence, the volume of the bacteria cell in 6.741 × 10^-10 L is 674.1 pL

Explanation:

A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.

Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).

The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Answer:

B. A proton gradient across a membrane.

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

In cellular respiration, the energy for most ATP synthesis is supplied by proton gradient across a membrane.

This ultimately implies that, most adenosine triphosphate (ATP) is formed due to the net movement of protons against a concentration gradient in the electron transport chain.
