Answer:
Pros:
You can get more scientific knowledge of the mammothYou will be able to clone the mammoth easierHelping the environmentIt will help protect species that are close to extinction(can't think of anything else, sorry )Cons:
Different environmentCould go wrong and become an alienCould carry retroviruses which can harm humansMight CHANGE the environment for the worseIt might cause more species to go extinctWhich of the following is a problem that could result from poor monitoring of free range grazing?
The increased use of antibiotics
The additional exposure of soil layers
The prevention of invasive plant species
The higher rates of mental illnesses in animals
Answer:
The additional exposure of soil layers.
Explanation:
Antibiotics are administered by humans, so less contact with humans won't cause an increased use of antibiotics. The prevention of invasive plant species is not a problem, nor would it be caused by improper management of free range animals. Mental Illness in animals is usually caused by being put in small enclosure or living in poor conditions, not by being allowed free range. Therefore, the answer is the additional exposure of soil layers, since excessive grazing can decimate plant and soil layers.
I hope that helped!
Answer:
The additional exposure of soil layers

you don need to actually chew the bread. you can just break it up into smaller pieces. which variable will you change in your investigation?
Answer: The type of bread (independent variable)
Explanation:
You can just change the type of bread you are eating and just hold it in your mouth to test your hypothesis of not having to chew the bread. It’s the easier thing to change when making the experiment. Now your bread is your independent variable because you are not changing anything else but the type of bread. Not sure if your question is talking about the technical terms for the variable or what actual variable in the experiment, so I put down both.

narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose. Draw a punnett square to determine the possible types of noses their children could have had. (Use the genotypes from #2) a. List the possible genotypes and phenotypes for their children. 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:
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
There is 50% chances for a child to have a stubby noseThere is 50% chances for a child to have a long noseThese children are not purebred----------------------------

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
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.

Why can’t a virus reproduce on its own?
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.What does it mean for the brain to process information contralaterally?

Possible setbacks are the difficulty in keeping up with market changes, failures in product production, failures in product distribution, sector problems, problems in the management of employees.
We can arrive at this answer because:
The management of a company is essential for its proper functioning and the success of the production.One of the first problems that lack of management causes is the difficulty in keeping up with market changes. This makes the company outdated and inefficient.Talking about the production and distribution of the product harms sales and reduces the number of customers.Sectoral problems hinder organized production, which will also affect sales.Problems in managing employees will also be disadvantageous, as it will affect all of the company's compositional factors.Therefore, we can say that management is the most important point to be organized.
