Answer:

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

1) How is DNA condensed to form a chromosome?

frosja888 [35]

Answer:

Hello! Here are the answers:

Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.

Explanation:

* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.

* 3. The genetic code determines the sequence of amino acids in various proteins.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t

Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² + 2pq+ q² = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = $\sqrt{0.35}$ = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
