Answer:
(V-Vo)/t = (30-0)/4 = 7.5 m/s^2.
I remember this from last year haha. The dark moths populations will go down since they can’t blend in as well as the light moths.
Large blue whales that are up to 30 meters long live primarily on krill that is/are only about 6 cm long.
Blue whales belong to the class of mammals. They are the largest animals on the Earth. They live in marine habitat. They can be more than 100 feet long. The weight of a single whale can be equal to 30 elephants. And they can live for as long as 80-90 years.
Krill are small animals belonging to the class of crustaceans. They are present in oceans. Krill are actually zooplanktons. They are majorly the food of whales. Krill are filter-feeders.

There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart. Our outer layer of skin is epithelial tissue.
If a linear piece of DNA has three sites for a particular restriction enzyme, it will be cut into 4 fragments. If the DNA is circular, the number of obtained fragments will be N for N recognition sequences for the specified restriction enzymes however if the DNA is linear, the number of obtained fragments will be (N+1).
A bacterial protein called the restriction enzyme cleaves DNA at specific locations. The recognition sequences, or short and distinct nucleotide sequences, are recognized by restriction enzymes in DNA. When a DNA sequence is recognized by the restriction enzyme, it hydrolyzes the bond between neighboring nucleotides and cleaves the DNA molecule.
The restriction enzymes guard against bacteriophages on the living bacteria. They identify the bacteriophage and cleave at its restriction sites, destroying its DNA.
The use of restriction enzymes in genetic engineering is crucial. In order to introduce foreign DNA for gene-editing purposes, restriction enzymes cut DNA at a specified location, which makes them a crucial tool.
