Answer: First and third Options are correct.

Explanation:

As we know the equation of photosynthesis :

Water + carbon - dioxide ----- glucose + oxygen

So, if the plants was exposed to more intense light and The plant absorbed more carbon dioxide, then the glucose level in the plants get increased.

Hence, First and third options are correct.

The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence, such as
svp [43]
1. Red-shift, which is basically the Doppler Effect, but with light. Because stars in other galaxies appear to give off red light, this shows that they are moving away from us (Earth). Red light is on the far left of the Visible Light Spectrum, so things moving away from us appear to be red, while things moving towards us appear blue (the other end of the spectrum). This suggests that the universe is expanding all the time - and therefore it might have started from a single explosion - the Big Bang.

2. Cosmic Microwave Background Radiation (CMBR) has been found by scientists to be coming from all directions in space, and is suspected to be 'left over' energy from the Big Bang.

A detective finds a miniscule spot of blood on a murder suspect’s shirt. What method would the police lab be expected to use to
WARRIOR [948]

Answer:

Polymerase chain reaction (PCR)

Explanation:

Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.

The fact that plants can be cloned from somatic cells demonstrates that _____.A) differentiated cells retain all the genes of th
mojhsa [17]

Answer:

The correct answer is A) differentiated cells retain all the genes of the zygote

Explanation:

A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.

All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.

This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.

Gene A has two alleles (A1 and A2). A1A1 homozygotes are twice as likely to survive from birth to reproductive age as heterozygo
Usimov [2.4K]

Answer:

The correct answer is C: <em>0.60 </em><em>A1</em> and <em>0.40 A2</em> will be the allele frequencies in those progeny when they reach reproductive age

Explanation:

<em>Genotype</em>                                <u><em>A1A1 </em></u><em>  </em><u><em>A1A2</em></u><em> </em><u><em>A2A2 </em></u>

<em>Relative aptitude, w</em>                  1           0.5    0.5

<em>Number of individuals</em>                 40            40     40

<em>Initial allelic frequency</em>      p0= (40+20)/120=0.5    q0= (40+20)/120=0.5

<em>Zygote frequency</em>                  p2= 0.25 2pq=0.25 q2=0.625

<em>Relative contribution</em>         0.25x1=0.25     0.5x0.5=0.25 0.25x0.5=0.125

<em>of each genotype</em>              

<em>Average aptitude W</em>              W= 0.025 + 0.25 + 0.125 = 0.625

<em>Population</em>                    AA= 0.25/0.625    AB=0.25/0.625  BB=0.125/0.625

<em>Genotype frequency</em>             AA= 0.4             AB=0.4          BB=0.2  

<em>New Allelic frequency</em>       p1=0.4+(0.4/2)=0.6   q1=0.2+(0.4/2)=0.4

  • <em>Total number of individuals</em>: 120
  • <em>Initial allelic frequency</em>:

                  (number of homozygote individuals + half number of  

                   heterozygote individuals) / Total number of individuals

  • <em>Relative contribution of each genotype</em>:

                           Zygote frequency x Relative aptitude

  • <em>Average aptitude W</em>: It is the sum of relative contribution of each genotype to the next generation.  

                    wA1A1 x p2 + WA1A2 x 2 x p x q + WA2A2 x q2

  • <em>Population Genotype frequency</em>:

                Relative contribution of each genotype / Average aptitude

  • <em>Allelic frequency</em>:

                      Homozygote population genotype frequency +  half  

                           heterozygote population genotype frequency
