Answer:
Volcanic gases. (Ans A)
Explanation:
Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.
In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
Answer:
The sequence of the complementary strand of mRNA is AUCAUCAUC
Explanation: There are four bases in DNA: Adenine A, Thymine T, Guanine G, and Cytosine C while the bases found in RNA are Adenine A, Uracil U, Guanine G, and Cytosine C. In DNA base pairing, Adenine pairs with Thymine while in RNA base pairing, Adenine pairs with Uracil while Guanine pairs with Cytosine.
When the organism is preserved in ice.
C. low humidity , when humidity is low it’s cooler outside which would be the best time for crystalline to form
This statement is true.
In the case of autosomal dominant disease, the person is either homozygous (which is very rare) or heterozygous. On the molecular level, either the mutation produced a new deleterious protein for the organism, or the mutation affected an existing protein in the physiological state and that a 50% activity is not enough to compensate for the needs. of the body.
In case of autosomal recessive disease, the sick person is always homozygous. If the two loci each have a different mutant allele, it is called a "composite heterozygote". People with autosomal recessive inheritance disorder have "mandatory heterozygote" parents.
