It uses energy

It evolves.

It grows and develops.

It is made of cells.

2.Compare a virus to a unicellular organism.(1 point)

Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.

Neither unicellular organisms nor viruses respond to stimuli.

Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

Viruses need energy; unicellular organisms do not need energy.

3.Summarize the lytic cycle.(1 point)

A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.

A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.

The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.

A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.


4.Differentiate between the lysogenic and lytic cycles.(1 point)

The host cell copies its own DNA during the lytic cycle.

The host cell is destroyed during the lytic cycle.

The virus injects DNA into the host cell during the lysogenic cycle.

Viral proteins are synthesized during the lysogenic cycle.

5.Infer why doctors recommend people, especially elderly and those with weak immune systems, get the flu vaccine every year.(1 point)

They should get the flu vaccine because viruses mutate.

They should get the flu vaccine because their bodies already have a resistance.

They should get the flu vaccine because viruses do not mutate.

They should get the flu vaccine because their bodies do not build up resistance.

Answer 2

The trait of living things that's depicted by a virus that mutates is that it evolves.

The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

The lytic cycle is when a virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

The difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.

The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.

It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.

People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.

Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.

In conclusion, the correct options are B, C, D, B, and A.

Answers

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.  

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.

Answers

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous

Answers

Answer:

The correct answer is -

A) BbTt x bbTt

B) .5^4 or 1/16 or 0.0625

Explanation:

As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.

For Branchydactylus and For tasting :  man and women will be heterogeneous.

Hence,

The Genotype of man = BbTt

The Genotype of wife = bbTt

b. Answer = 0.0625

For Branchydactylus:

Bb X bb

Possible genotypes:

B b

b Bb( Brachydactylus) bb(normal)

b Bb (Brachydactylus) bb (normal)

The probability of a single child being Branchydactylus = 2/4 = 0.5

So,  Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

InformationHow did
the discovery of isotopes disprove one part of
Dalton's atomic theory

Answers

Answer: Because Daltons theory states all atoms of a given element are identical in mass and properties.

Explanation:

The discovery of isotopes demonstrated that atoms of the same element can have different atomic weights, implying that atoms of the same element are not identical in every way. 

What is Dalton's atomic theory?

Dalton's atomic theory postulated that matter is made up of indivisible particles known as atoms, and that atoms of the same element are all identical and cannot be created or destroyed.

Compounds are formed by the simple combination of atoms into compound atoms.

Dalton, John Experiments with gases became possible at the turn of the nineteenth century, prompting John Dalton to propose a modern theory of the atom based on certain assumptions.

Dalton's theory is debunked. This is because Dalton's theory states that all matter is made up of identical, indivisible, and indestructible atoms. Isotopes have the same element but a different number of neutrons.

Thus, this way, the discovery of isotopes disprove one part of Dalton's atomic theory.

Answers

Answer:

Between depths of tectonic plate boundaries and the outer core.

Explanation:

The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core.  At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.
