Energy producing technologies can positively impact soil fertility

Answers

That statement is true

But it depend on what type of energy producing technologies you're talking about.

BioChar , a technology that uses Charcoal to produce energy will positively impact soil fertility because it is really rich in carbon.

On the other hand Nuclear related energy producing technology can negatively impact soil fertility

Why is testcross necessary to determine genotype when an organism shows a dominant trait?

Answers

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
Since dominant trait results from a dominant allele, the test cross can determine if unknown genotype is heterozygous and homozygous dominant.

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is heterozygote, and aa is recessive homozygote.
According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).

Limestone is made up of calcium carbonate. How would you expect the pH of the lake with limestone bedrock to compare with other lakes with several years of acid rain.

Answers

Answer:

See the answer below.

Explanation:

One would expect the pH of a lake with limestone bedrock to be higher than that of other lakes with several years of acid rain.

A lake with a bedrock made of limestone would be alkaline due to the weathering of the bedrock and the alkaline nature of calcium carbonate. Lakes with several years of acid rain would, of course, be acidic.

Generally, pH above 7 is alkaline while the ones below 7 are acidic. Hence, the pH of a lake with limestone bedrock will be higher (above 7) than the pH of other lakes with years of acid rain (below 7).

what do u mean by this chromosones contain information of inheritance of character from parent to next genration in the form of dna

Answers

Answer:

Explanation:

DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.

So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)
