Answer:
B
Explanation:
since the impulse is moving form Q to P ...Q will be the receptor and P is the relay neuron which will transfer the impulse to the next neuron
It gets plasmolysed due to exosmosis.
Answer:
If the producers would be removed in the food web, then the whole ecosystem would fall down and die.
Explanation:
The reason why producers are important in a food chain is because they provide food for the herbivore animals, and then, the carnivore animals kill and eat the herbivore ones, and whatever is left, is eaten by the decomposers. So, if we remove the root of the tree (producers), then can the tree(rest of food web) survive? The simple answer is NO.
So, Hence, the ecosystem won't be able to last long, all animals will die.
Answer:
1. It could result in a loss of function of the protein product
2. It could result in a protein product with excessive activity
3. It could result in altered structure of the protein
Explanation:
Any changes that occur in the nucleotide sequence in the DNA of an organism is known as a mutation. Various forms of mutation can occur in the DNA sequence of an organism which could be as a result of insertion or deletion of a nucleotide in the DNA sequence.
Insertion of an extra nucleotide into a DNA strand within a gene could have any of the following effects on the protein protein;
1. It could result in a loss of function of the protein product of the gene whereby the protein can no longer carry out its normal functions
2. It could result in a protein product with excessive activity other the normal range at which it functions.
3. It could result in altered structure of the protein either in the primary, secondary, tertiary, or quaternary structure
