The answer is biomagnification. <span>Bioaccumulation</span> involves <span>the
build-up</span> of a pollutant from the environment to an organism in a food
chain. Biomagnification refers to the tendency of pollutants to concentrate as
they move from one trophic level to the next. The substances become
increasingly concentrated in tissues or internal organs as they move up the
chain.
Answer:
1. CGAGGTT → CGTT (Deletion)
2. ATTCGG → ATTCGGATTCGG (Duplication)
3. CTTAAT → TAATTC (Inversion)
4. CTTAAT → CTTAACGCT (Insertion)
5. CGAT → CTAT (Substitution)
6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation)
Explanation:
1. CGAGGTT → CGTT (Deletion) ---- This is called deletion because it involves the removal of 3 base pairs (AGG) from the DNA sequence.
2. ATTCGG → ATTCGGATTCGG (Duplication) ---- In this case, the particular sequence (ATTCGG) is copied again or duplicated.
3. CTTAAT → TAATTC (Inversion)----- This is called inversion mutation because the DNA sequence breaks off and is reattached but this time in a reverse order i.e. CTT becomes TTC, placing the last base first and the first base last.
4. CTTAAT → CTTAACGCT (Insertion) ------ This is called insertion mutation because it involves the addition of extra base pairs (CGC) into the sequence. The Insertion occurs between the last A and T nucleotide.
5. CGAT → CTAT (Substitution) ----- This is called substitution because Guanine base is replaced by Thymine in the DNA sequence. It is specifically called a transversion substitution because a purine (Guanine) is replaced by a pyrimidine (Thymine). It is called a point mutation because it involves a single base.
6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation) ----- in this case, CCGGTT and TTAGGC are sequences on different chromosomes. Portions of sequence on the first chromosome (GTT) and second chromosome (TTA) breaks off and gets reattached/exchanged in each other i.e. the first chromosome gets TTA while the second gets GTT. This kind of mutation is called translocation.
Actually it is the females the mostly build the nests the males will help build it sometimes both males and females will build it but typically it is females and that goes for all birds.
"Females typically build nests, but sometimes both parents or just the male"
Answer:
its not a or d I know that
Explanation:
In adults aged 20 and older, the average daily vitamin K intake from foods is 122 mcg for women and 138 mcg for men. When both foods and supplements are considered, the average daily vitamin K intake increases to 164 mcg for women and 182 mcg for men.
