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!!

Answers

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.

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.

Mr. Attis

Answers

Answer:

its human activity that change ecosystems

Ecosystem survival during earth change is helped by biodiversity, which produces a quality environment, hence option b is correct.

What factors affect the ecosystem?

Ecosystem drivers encompass both natural and human-made elements. For example, habitat change and over-exploitation are direct causes that overtly affect ecological processes.

The effects of human activities on land and in the sea may have a significant impact on ecosystems. Among the various issues that ecosystems face include climate change and ocean acidification.

Biodiversity produces a quality of the environment that combine with oxygen, clean air, and water, pollinates plants, controls pests, treats sewage, and provides a wide range of other ecosystem services.

Therefore biodiversity provides an environment for the ecosystem when the earth changes, hence option b is correct.

Which purpose does a cell membrane play in eukaryotic cells?

Answers

The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

A peptide has the sequence of Gly-Ser-Glu-Leu-Ala-His-Gly-Arg-Leu-Ala-PheCys-Leu. (pKR=4.25, 6.0, 8.2, 12.5. Assume pKa’s of amino terminus and carboxyl terminus are 9.6 and 2.3, respectively.) The PI of the peptide is close to:_______

a. 7.1
b. 7.8
c. 5.1
d. 8.2
e. 10.3

Answers

Answer:

The correct answer is option a. "7.1".

Explanation:

One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.

Answers

Answer:

Bare soil is exposed, weeds and grasses colonize, perennial plants are established, shrubs appear, trees appear, and forest results

Explanation:

This question describes a secondary succession, which is a colonization that occurs after a natural disaster has caused damage to an ecosystem. In secondary succession, SOIL, is already present, hence, there is rapid initial recolonization by GRASSES AND WEEDS.

The colonization of grasses and weeds is soon followed by the establishment of PERENNIAL PLANTS, after which SHRUBS appear, then TREES until a stable or climax ecosystem of FOREST results.

Explanation:

A predatory fish evolves adaptations that make it more adept at catching smaller fish. In turn, the smaller fish evolve means to be evasive, leading to more selection on the predators to be still better able to catch their prey. The interaction between the two species is an example of a(n)

Answers

Answer:

an evolutionary race (i.e., coevolution)

Explanation:

Coevolution is a phenomenon where two or more species affect each other's evolution through the mechanism of natural selection. During coevolution, species start an evolutionary race, where one species adapt and change (i.e., evolve) in response to another species, thereby countering the adaptive effects of the first one. An example of coevolution is the evolutionary race between predators and preys, like the example above.

The interaction between the two species is an example of a(n) coevolution. To understand more about it......

Arms race

In the coevolutionary arms race, there is selection pressure on both prey and predator. The predator evolves to catch the prey, and mutually the prey evolves to escape the predator. These arms race can be seen in Cenozoic mammals, where the size of the brains of predators and prey increased relatively over time. As the brain size of predators grew to become smarter to catch prey, the brain size of prey also grew to become smarter and able to escape predators. This process is called climbing coevolution, where predator adaptations are neutralized by prey adaptations, with no advance occurring. As a result, current predators are no better at capturing their prey than ancestral predators. Different from what happens in the evolutionary process, where evolution generates organisms that are better adapted than others

With this information, we can say that the coevolution of predator and prey is common in nature, and determines the survival of these species involved.

Answers

Answer:

size of that species’ population.

Explanation:

The increase in the reproductive success of a species will have the greatest impact on the size of that species’ population.

A reproductive success rate means more individuals survive birth and get added to the existing population. The more the number of individuals added to a population, the more the size of the population of the species.

An increase in the population size of a species will only increase intra-species competition for resources but have no real impact on the success of other populations in the community.

Answers

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.

Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular proteins would be the target of your drugs?

Answers

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
