Population study in ecology is a broad topic to be studied, in order to answer this question we must know that .......

<h3>Population </h3>

A population, in Ecology, can be defined as a set of individuals of the same species that live in a given area in a given period of time. Individuals in one population are more likely to interbreed with each other than with organisms in another population of the same species.

<h3>Population dynamics</h3><h3> </h3>

Population dynamics is the study of how and why populations change in size and structure over time. Important factors in population dynamics include rates of reproduction, death and migration.

With this information, we can say that" Ecologists conduct population studies to understand population dynamics by investigating how the <u>number of individuals</u> increases or decreases over time.

<u />

<u>We can conclude that these studies in </u><u>Population dynamics </u><u>are of great relevance to visualize the characteristics of </u><u>populations</u><u>.</u>

<u />

Design an experiment to test this claim “If the samples are made of different materials, they will heat up at different rates” T
vitfil [10]

Answer:

Yes, the statement is true.

Explanation:

Different substances requires different amount of heat because every materials has its own specific heat capacity. Heat capacity is the amount of heat required to increase its temperature by 1 degree. Different substances have different types of bonds due to which they required different amount of heat energy for its breaking.

For example, heat requirement of water is different from  glucose because they are made of different substances.

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.
mote1985 [20]

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 <em>different potential scenarios </em>for this question.

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

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

<h3 /><h3><u>SCENARIO 1</u>  ⇒ long nose is the dominant trait</h3>

Let us say that

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

Since long nose is dominant over stubby nose

  • LL and Ll ⇒ long nose
  • ll ⇒ 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.

<u>Cross 1</u>

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

  • <em>There is 100% chances for a child to have a long nose</em>
  • <em>There is 0% chances for a child to have a stubby nose</em>
  • <em>These children are not purebred</em>

                                             **********

<h3><u>SCENARIO 2</u>  ⇒ Stubby nose is the dominant trait</h3>

Let us say that

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

Since stubby nose is dominant over long nose

  • SS and Ss ⇒ stubby nose
  • ss ⇒ 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.

<u>Cross 1</u> : 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

  • <em>There is 100% chances for a child to have a stubby nose</em>
  • <em>There is 0% chances for a child to have a long nose</em>
  • <em>These children are not purebred</em>

<u>Cross 2</u>: 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

  • <em>There is 50% chances for a child to have a stubby nose</em>
  • <em>There is 50% chances for a child to have a long nose</em>
  • <em>These children are not purebred</em>

Why did mendel use cross pollination and not self pollination
Studentka2010 [4]

He wanted to see how different traits passed through the pea plants he grew. To do this, he needed to cross polliante so that their were multiple parents affecting the genes of the new pea plant. If he self pollinated, all the new baby pea plants would Look the same as their parents and we wouldn't know as much as we do about genetics now
