In the answer we have (CRCR) 1/4
(CWCW)1/4
(CRCW) 2/4
They are called casts. CASTS
The DNA of a human cell can be cut and rearranged by using Enzymes. To cut DNA into smaller segments, enzyme nucleases are used. They do this by taking the phsophodiester bonds through hydrolysis and catalyzing it. when these enzymes comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the molecule.
Answer:
d. They are often keystone species
Explanation:
Top predators in an environment are the largest predators and sits on the top (apex) of the food chain in an ecosystem which do not have any natural predators.
As the top predators relative to its abundance has disproportionately large effect on its natural environment, they are the keystone species most of the time.
Hence option d. They are often keystone species is the right option.
The question is stated incorrectly. The correct question is as follows;
The site of intercellular communication between a neuron and another cell is the.
Answer:
Synapse.
Explanation:
Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.
Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.
Thus, the correct answer is synapse.
