Which of the following must be true in order for natural selection to occur?

Group of answer choices

There must be variation in traits in the population

The trait must cause the individual to evolve

The trait must have no other advantage in fitness

The trait must be for the good of the species

The trait must be heritable

The trait must advance the goal of evolution

Answers

Answer:

For natural selection to occur, it is true that there must be genetic variation in the population.

Explanation:

According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.

For natural selection to occur, three fundamental conditions must exist:

A trait that can be inherited from one generation to another.

The trait is subject to variability between subjects of the same species.

Genetic variability can determine the possibility of reproductive success and survival.

Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.

For natural selection to occur :-

There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.

What is Evolution?It is the change in the characteristics of a species over several generation.It relies on the process of natural selection.

Which of the following is a correct association?

Answers

Answer:

The first one

Explanation:

because it has the most words on their.

The correct association is option a.The cell synthesises proteins and organelles in the G2 phase (also known as the "Gap 2 phase") of the cell cycle in order to prepare for cell division.

The cell enters the G2 phase following DNA replication, which takes place during the S phase. In order to manufacture the elements required for cell division, the cell continues to expand and goes through further protein synthesis during this phase. These proteins play a role in the development of the mitotic spindle, control of cell cycle checkpoints, and cytoskeleton organisation.

The cell also creates organelles like the mitochondria and endoplasmic reticulum to make sure there will be enough energy and cellular building blocks for the impending division in the phase.

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

Gametes)  S    s     s    s

Punnett square)   S       s

                      s     Ss     ss

Describe the three methods for harvesting stem cells, for each method, explain the benefits of the method and the ethical concerns related to the method

Answers

Answer:  These stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.

Explanation: Describe the three methods for harvesting stem cells, for each method, explain the benefits of the method and the ethical concerns related to the method

Stem cells are specialized cells that can proliferate into many types of cells lineages. Umbilical cord blood collection, bone marrow harvesting and dental pulp collection are the methods.

What are stem cells harvest methods?

Stem cells can be collected from the blood and the tissues of the umbilical cord of the baby born and is an easy method that collects the cells from the umbilical cord and the placenta for future use.

The cells and the tissues are chopped and kept in the low temperatures that include the Mesenchymal stem cells in it. They are beneficial as they can treat cancers, anaemia etc. There are not many ethical issues related to umbilical cord use.

Stem cells can be derived from the bone marrow as this is the site where they originate from. The method uses the removal of the bone marrow from the pelvic bones and subjects them to the removal of the stem cells from the blood.

Stem cells from the bone marrow are used for the replacement of damaged cells. The use of the bone marrow and using human lives is the ethical issue concerned with bone marrow based stem cells.

The dental pulp collection method of the stem cells uses the method of deriving cells from the teeth region and are a source of the bone and the mesenchymal cells.

DPSCs can be used for cell banking and are the method that has no ethical concerns. It is simple can be done in dental routines.

Therefore, umbilical cord, dental pulp and bone marrow are the stem cells collection methods.

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.

Select the TRUE statement about a resting neuron. a.) The cytoplasm side of a neuron is positively charged while the outside of the neuron has no charge. b.) The cytoplasm side of a neuron is negatively charged while the outside of the neuron is also negatively charged. c.) The cytoplasm side of a neuron is more negative than the outside of the neuron. d.) The cytoplasm side of a neuron is more positive than the outside of the neuron.

Answers

Given what we know about the nervous system and resting neurons, we can confirm the cytoplasm side of a resting neuron is more negative than the outside of the neuron.

What is a neuron?Neurons are specialized cells that make up the nervous system in the body. Their primary function is to act as messengers, delivering information in the form of electrical impulses and neurotransmitters. These neurons work using rapid shifts in membrane potentials.In order to do this, the starting value or resting point of the membrane is negatively charged.

Therefore, we can confirm that since neurons function using shifts in membrane potentials, the starting point or resting form of a neuron has a negatively charged membrane, meaning that the cytoplasm side of a resting neuron is more negative than the outside of the neuron.

Could there be winds without differential heating? Using evidence from Unit 5 explain what differential heating is and whether this effects the earth’s global wind patterns.
HELPPP PLEASE SITE EVIDENCE (WILL MARK BRAINLIEST)!!!!!!!!

Answers

Differential heating is responsible for the wind patterns across the globe.

Differential heating is defined as the difference in heating of air on the land versus water. Sea breezes occur when land heats up faster than water which rises and creates a low pressure system. The high pressure air from the sea influxes is responsible for the creation of a sea breeze.

Unequal heating of the Earth's surface is responsible for the formation of large global wind patterns. Warm air rises at the equator and moves toward the poles while on the other hand, the cooler air rises at the poles and moves back toward the equator so in this way the earth’s global wind patterns occurs so we can say that differential heating is responsible for the wind patterns across the globe.
