Answer:
Intermediate neuron
Explanation:
Interneurons are the "middle man", neither a sensory or motor nueron, that creates neurial circuits, connecting a broad class of neurons in the spinal cord and brain. They enable communication from motor and sensory neurons in the central nervous systems and are classified into two groups; relay and local interneurons. Through neurial circuits, the brain is able to manage and deal with complex stuff such as decision-making and learning.
A. Polysaccharide, this is because polysaccharides have cellulose which make the grass stand up.
Answer:
47
Explanation:
We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.
But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
Answer:
Enzymes are proteins that act as biological catalysts. Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
