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.

After formulating wh questions, it's time to form a hypothesis or an educated guess, but how do we do this?
First, you must gather the knowledge you already know; ad back it up with something that has happened like a study, article, etc

This will be the base of your hypothesis, and from here, just add the knowledge of which you know that can make up a well supported hypothesis, which you will then test.
Example:
It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe.

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
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

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.

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 traitLet us say that
L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby noseSince long nose is dominant over stubby nose
LL and Ll ⇒ long nosell ⇒ stubby noseIf 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 traitLet us say that
S is the dominant allele and codes for stubby noses is the recessive allele and codes for long noseSince stubby nose is dominant over long nose
SS and Ss ⇒ stubby nosess ⇒ long noseIf 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 purebredCross 2: Violet is heter0zyg0us, Ss
Parentals) Ss x ss
Gametes) S s s s
Punnett square) S s
s Ss ss
s Ss ss
F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss
Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

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. please help me on this its due in class
