Answer:
+1, -1, +2, -2, +3, and -3 are the answers :)
Explanation:
Answer:
C. endonuclease
Explanation:
Endonuclease is a type of enzyme which involves the use of its properties to cleave the phosphodiester bond which are available in a polynucleotide chain such as DNA or RNA.
This enzyme cuts the pre-mRNA between the AAUAAA consensus sequence and a GU-rich sequence before translation takes place in a DNA. This explains why the right choice is an Endonuclsease.
C
Punnett squares are only used for predictions, as they can’t accurately measure/county anything.
Answer: From signalling to disease. ... Also sometimes the signal cant pass from one cell to the other. An example of this is in the diseases of multiple sclerosis in where the nerve cells can no longer transmit signals from one area of the brain to another
Explanation:
Phytoplankton, <span>Zooplankton are “animal-like” plankton that include tiny animals and fish larvae. They feed on phytoplankton.</span>
The phytoplankton (left) and zooplankton (right) shown here have been magnified. Otherwise, they would be too small for you to see.
Nekton
Nekton are living things that swim through the water (Figure below). They may live at any depth, in the photic or aphotic zone. Most nekton are fish, although some are mammals. Fish have fins and streamlined bodies to help them swim. Fish also have gills to take oxygen from the water.
Nekton swim through ocean water.
Benthos
Benthos are living organisms on the ocean floor. Many benthic organisms attach themselves torocks and stay in one place. This protects them from crashing waves and other water movements. Some benthic organisms burrow into sediments for food or protection. Benthic animals may crawl over the ocean floor. Examples of benthos include clams and worms. Pictured below are two other examples (Figure below).
These animals live on the ocean floor.
Some benthos live near vents on the deep ocean floor. Tubeworms are an example (Figurebelow). Scalding hot water pours out of the vents. The hot water contains chemicals that some specialized bacteria can use to make food. Tubeworms have the bacteria living inside them. The bacteria get protection and the tubeworms get some of the food.
Tubeworms live near hot water vents on the deep ocean floor.
