A strategy for fighting bacterial infections uses viruses. Viruses that infect bacteria are called bacteriophages. Phage comes from the Greek word for “eater.” Explain why it is not accurate to call a virus that kills bacteria a “bacteria eater." What happens when a virus attacks a cell?
help!!
Answer:
Viruses are not living organisms, and for that reason a bacteriophage virus does not feed on bacteria, but uses them to replicate, producing lysis of the bacterial cell in the process.
Explanation:
Viruses are structures formed by genetic material —DNA or RNA—covered by a protein envelope called the viral capsid. These structures do not perform the vital functions of a cell, so they are not considered living organisms.
A bacteriophage virus is characterized by using prokaryotic cells to replicate, destroying them in the process.
Viruses need a living cell to be able to replicate, so they introduce their viral genome into them to replace the genetic material of their nucleus and be able to multiply. They can do this:
Introducing the genetic material from outside the cell. Entering directly into the cell to be able to replicate.Bacteriophage viruses do not eat the bacteria, they simply use it to reproduce, and then happens the lysis of the bacterial cell.
Answer:
Viruses are not living organisms, and for that reason a bacteriophage virus does not feed on bacteria, but uses them to replicate, producing lysis of the bacterial cell in the process.

A construction company has clear-cut all the plants on the land next to a river. It plans to build many large homes on the land. During the construction, there are
periods of heavy rain. Large areas of red mud run off into the water, causing the water to become extremely cloudy. Which effect will these mud particles most
likely have on life in the river?
A) The mud particles will decrease the turbidity of the water, making it less difficult for plants to photosynthesize.
B) The mud particles will decrease the turbidity of the water, making it more difficult for plants to photosynthesize.
C) The mud particles will increase the turbidity of the water, making it less dificult for plants to photosynthesize.
D) The mud particles will increase the turbidity of the water, making it more difficult for plants to photosynthesize.
Answer: C). The mud particles will increase the turbidity of the water, making it more difficult for plants to photosynthesize.
Explanation:
The run off of the red soil and the construction material in the form of mud particles will contaminate the river water. This will increase the turbidity of the water of the river. The turbidity will not allow the penetration of sunlight into the river water as a result the plants will not get sunlight which is necessary for the process of photosynthesis. In the presence of sunlight the green plants prepare their own food by using carbon dioxide and water so as to produce the carbohydrates in the form of food.
Which term best describes the macromolecule shown below? А monosaccharide В polysaccharide С amino acid D nucleic acid
Answer:
B. Polysaccharide
Explanation:
A polysaccharide is a carbohydrate molecule made up of several units of monomers called monosaccharides linked together by glycosidic bonds. The monosaccharide is the simplest unit of a carbohydrate with the general formula, (CH2O)n.
However, the monosaccharides, which include glucose, fructose, galactose etc can link up by a bond to form a much larger carbohydrate molecule called POLYSACCHARIDE. As depicted in the image attached to this question, each ring is a monosaccharide, which becomes linked to one another to form a polymer called polysaccharide. Examples of polysaccharides are starch, glycogen, cellulose
One example of evolution and natural selection is:
O a. Arctic Foxes changing coat color in the winter, from brown to white.
O b. Lung fish being able to survive out of the water.
O c. Pigeons nesting and living in an urban environment,
d. All of the above
Answer:
D. All of the above
Explanation:
Evolution by natural selection involves organisms being better suited to their environment as a result of the occurrence of changes in traits to enable it to reproduce more or have a higher chance of survival.
An example of evolution by natural selection involves Arctic Foxes changing coat color in the winter from brown to white, Lung fish being able to survive out of the water and Pigeons nesting and living in an urban environment.
In the natural selection simulation we set the fitness of rr individuals to 0. Why does the r allele persist in the population?
Answer:
In the clarification section elsewhere here, the definition of the concern is mentioned.
Explanation:
The notion of fitness seems to be the basic phenomenon of Fisher. Fitness is a dynamic term since it is the calculation by a person in his lifetime of the cumulative production of viable progeny. The fitness of an organism is zero even though no offspring is created. With a growing life span as well as the amount of order to promote innovation, flexibility increases. Members of an organization that are very well-adapted to that certain range of environmental factors have had a benefit in the mechanism of selective breeding over others who might not be as possibly the best adapted. The benefit falls throughout the form of genetic diversity and longevity. Those people who are much more able to easily find and use food supplies, for example, would live considerably longer and have more offspring than someone who is less reliable at seeking food. Inherited features that increase human fitness are then passed on to their descendants, thereby providing this very same value to the descendants. The disappearance of fewer adapted varieties seems to be the most drastic alternative. Unless the best-adapted variant doesn't adjust even though it is as when the optimum balanced local, so for the ideal characteristic, less drastic will delete both-new variant.Since less drastic selection has become too inadequate to aggressive edge mutations, the aggregation of missense mutations will happen and even the outcome would be a progressive deterioration of genomic integrity. If it maintains you prolonged enough, this should contribute to disappearance for certain species; nevertheless, the subsequent widespread presence of the deleterious mutations just seems like such a genome would then inevitably also contribute to backward mutation incidence. Extinction could result if the intense choice has become too high for the entire world, because if the world is saved in time.There are several different kinds, but the one you pick doesn't do its job?

Select the true statementabout unmyelinated axons:A. action potentials occur everywhere along the length of the axon, and propagation is faster than in myelinated axons.B. action potentials occur everywhere along the length of the axon, and propagation is slower than in myelinated axons.C. action potentials occur only at some points along the axon, and propagation is fasterthan in myelinated axons.D. action potentials occur only at some points along the axon, and propagation is slower than in myelinated axons.E. Unmyelinated axons do not exhibit action potentials.
Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.

A.
Lane 7
B.
Lane 2
C.
Lane 3
D.
Lane 4
its for Environmental Science
Answer:
Lane 4
Explanation:
Based on the information that is provided, it seems that the gel electrophoresis analysis was conducted to determine the presence or absence of carp DNA in water samples from six different sites.
What happens in the process of gel electrophoresis ?In gel electrophoresis, DNA fragments are separated based on their size and charge by applying an electric field to a gel matrix. The negatively charged DNA fragments move towards the positively charged electrode, with smaller fragments moving faster and migrating farther down the gel than larger fragments.
In this particular gel, lane 7 is the negative control, which means that it should not show any bands of DNA fragments. Lane 8 is the positive control, which should show a band of DNA fragments of known size and sequence. The purpose of the positive control is to ensure that the gel electrophoresis is working properly and that the expected band is present.
If the bands formed in lanes 1, 3, 5, and 6 correspond to the band in the positive control lane (lane 8), then it suggests that carp DNA may be present in the samples taken from those four sites.
However, it is important to note that this inference is based on assumptions and limited information provided, and a more thorough analysis and interpretation of the gel electrophoresis results would be required to draw definitive conclusions about the presence or absence of carp DNA in the water samples from those sites.

a. What is the major evolutionary advantage to producing an amnion?
b. What does that mean for embryonic development for the animal phylum as compared to the animal phyla?
WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?
The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.
WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?
The embryonic development of animal phylum is also known as embryogenesis.
It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.
This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.
This embryonic development of animal phylum comprises of 36 animal phyla.

If the pH of solution A is 10, and the pH of solution B is 2, then the concentration of H+ ions
Answer:
If solution A has a pH value of 10 which is greater than 7, it means that solution A is a base because all bases have pH value more than 7, while on the other hand, if solution B has pH value of 2 which is less than 7, this indicates that the solution is acidic.
Now, all acids have more concentration of H+ ions and they have less OH- ions, bases have less H+ ions and more of OH- ions.
So, Solution A = Higher concentration of H+ ions
Solution B = Less concentration of H+ ions.
