Answer:

Please find the explanation below

Explanation:

Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.

The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.

Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.

In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.

What is unusual about Earth’s mantle being exposed?
cluponka [151]

Answer:

There is no actual way that the mantle could be...'exposed' or 'seen'. But scientists have managed to find multiple ways to analyze the mantle and it's actual existence by using multiple devices. The mantle is basically a 2,900 kilometers (1,802 miles) thick blocks of rocks and minerals underneath the crust(or the surface of the earth) , and makes up a whopping 84% of Earth's total volume.

Distinguish between evolution and naturalselection.
Ugo [173]

Answer:

Evolution - It occurs due to the continuous variations and diversifications coming from the past generations

Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!

Evolution - Driven by natural selection

Natural Selection- Driven by new characters that are the results of mutations

Evolution - Duration of Action Acquires millions of years

Natural Selection -  Can be done in a short duration

Evolution - Example ;- Darwin’s finches, bright-colored peacocks, Mexican cavefish, etc.

Natural Selection -Example ;- Tree-frogs are mostly eaten by snakes, giraffes with short and long necks, etc.
