We have not been able to explore deep in the ocean, extremely cold climates, and some may have even been missed in "our backyard" because Earth is so diverse! According to National Geographic, "Even after centuries of effort, some 86 percent of Earth's species have yet to be fully described, according to new study that predicts our planet is home to 8.7 million species. ... So far, some 1.2 million species are known to science."

technology used for? (1 point)
Think about the methods used to analyze DNA.

Answers

The technology that was used to produce the results illustrated in the image is gel electrophoresis and it is used for separating deoxyribonucleic acid (DNA) fragments.

Gel electrophoresis can be defined as a technology that is used in the laboratory for the separation of mixtures of deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or other macromolecules such as proteins based on molecular size and charge.

In gel electrophoresis, an electric current is applied to the deoxyribonucleic acid (DNA) samples so as to create fragments that can be used to compare the various samples of deoxyribonucleic acid (DNA).

The steps involved in gel electrophoresis include the following:

Extraction of deoxyribonucleic acid (DNA).DNA isolation and amplification.Addition of deoxyribonucleic acid (DNA) to the gel wells.Application of an electric current to the gel.The separation of DNA bands based on molecular size and charge.Deoxyribonucleic acid (DNA) bands are stained.

Temperature-sensitive alleles are an example of conditional alleles; at the permissive temperature, the gene has normal function, whereas at the restrictive temperature, the gene has mutant function. You are studying the E2F pathway and you obtain a temperature-sensitive CDK4 mutant. At the permissive temperature, CDK4 functions normally. At the restrictive temperature, CDK4 is non-functional. Would you expect cells to continue growing or stop dividing when at the restrictive temperature? Explain your answer.

Answers

When at the restrictive temperature, we can comfortably expect the cell to stop dividing, whilst continuing to grow

The E2F pathway in a cell is responsible for the transition from the G1 stage of the cell cycle to the S stage. The G1 stage is where a cell grows and expands before the duplication of its DNA.

The S stage stands for synthesis. This is the moment in the cellular cycle in which the DNA of the cell is copied in order to prepare for cellular division.

Therefore, if the transition from G1 to S is blocked by temperature restrictions, we can expect the cell to continue growing, but not divide.

A mother has blood type A and her son has blood type O. Which blood types are possible for the father?

A

O

AB

B

Answers

i would say just O :) have a good day

Answer: Blood types O, A, and B are possible for the father.

Explanation: Since the mother has type A blood, there are two possible genotypes that she can have: AA or AO. Since her son has type O blood, he only has one genotype: OO.

For blood types,

Type A - AA or AO

Type AB - AB

Type B - BB or BO

Type O - OO

* A and B are dominant over O.

Now we have to do crosses between the mother and the father:

AA mother with AB father: child with type AA or type AB blood

AO mother with AB father: child with type AA, AO, AB, or BO blood

AA mother with OO father: child with AO blood

AO mother with OO father: child with AO or OO blood

AA mother with AA father: child with type AA blood

AA mother with AO father: child with type AA or AO blood

AO mother with AA father: child with type AA or AO blood

AO mother with AO father: child with type AA, AO, or OO blood

AA mother with BB father: child with type AB blood

AA mother with BO father: child with AB or AO blood

AO mother with BB father: child with AB or BO blood

AO mother with BO father: child with AB, AO, BO, or OO blood

The father can have blood types O, A, or B.

What are the chances of a child with a long nose? out of or % c. What are the chances of a child with a stubby nose? out of st or__% d. Would their children be considered purebred like Dobby? Explain:​

Answers

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

SCENARIO 1  ⇒ long nose is the dominant trait

Let us say that

L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nosell ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals)    LL   x    ll

Gametes)  L    L     l    l

Punnett square)    L       L

                      l      Ll      Ll

                      l      Ll      Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

     Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long noseThere is 0% chances for a child to have a stubby noseThese children are not purebred

                                             **********

SCENARIO 2  ⇒ Stubby nose is the dominant trait

Let us say that

S is the dominant allele and codes for stubby noses is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nosess ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals)    SS   x    ss

Gametes)  S    S     s    s

Punnett square)   S       S

                      s     Ss     Ss

                      s     Ss     Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

     Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby noseThere is 0% chances for a child to have a long noseThese children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals)    Ss   x    ss

Which option distinguishes what a commodities trader would do with the information in the following scenario?
A heat wave is expected to hit the central United States and cause a drought that will kill off many wheat plants.


sell off wheat supplies immediately at their highest price

immediately buy futures contracts at their current prices

cancel all options on future sales of wheat

wait until the heat wave to make wheat purchases

Answers

The commodities trader would immediately buy futures contracts at their current prices. The correct option is C.

Thus, a commodities trader would probably predict a decline in wheat supply if they learned about an anticipated heat wave and drought that may affect wheat plants. They would then buy futures contracts at their present levels in response.

By taking this move, the trader is able to protect himself against prospective price rises brought on by the decreased supply of wheat by securing the right to purchase wheat at a certain price in the future. The trader may be able to take advantage of the predicted market conditions before the impact of the heat wave is fully felt by purchasing futures contracts.

Thus, the ideal selection is option C.

Why can’t a virus reproduce on its own?

Answers

Answer:

Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.

At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.

They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).

A virus that infects bacteria is known as a bacteriophage, often shortened to phage.

The study of viruses is known as virology, and those who study viruses are known as virologists.It has been argued extensively whether viruses are living organisms.

Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.

They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.

A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.

Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.
