Well the niche of a squirrel mostly depends on the niche of a temperate rainforest.The trees need water and sunlight to make a nut.Then the squirrel finds the nut and stores it for the winter
Answer: K+ will flow from side 2 to side 1 until it is in equal concentrations in the two compartments
Explanation: A membrane potential will develop so that the electrical gradient stops the movement of K+ before equilibrium of the concentration can occur
Answer:
a. Bands at 1kb, 6kb and 8kb
Explanation:
The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.
The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.
In the given question, the
1. EcoRI- produces two strands of 7 kb and 8 kb
2. BamHI- produces two strands of 1kb and 14kb
This shows that the length of DNA sequence is 15kb
But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:
i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb
ii) 1 kb band is already produced by the Bam HI.
This shows that 1+6+8= 15 kb
Thus, Option-A is correct.
Pros:
It is (mostly) based on pyrethrine spray which kills the
insects rapidly.
It not poisonous to other animals.
It uses synthetic, natural spray which is safe to use because
it breaks down within 10 minutes.
Te technique can reach tall forests.
It can be used in closed spaces ( greenhouses, basements
etc).
Cons:
It requires windless circumstances ( which is mostly at
nights).
Breathing fog may cause respiratory and throat irritation to
some.
Answer:
Arteries at at a higher pressure than veins.
Explanation:
Arteries receive blood after the heart beats, putting them at a higher pressure. They are also thicker than veins as well.
