For cells that are larger, nutrient intake and waste elimination takes a longer time due to the larger distance that must be covered by the same transport processes as the ones taking place in smaller cells. Shapes that maximize surface area help increase the rate of nutrient uptake and waste elimination.
1 molecules of mgcl2 = 95.11
1 mole in 1 molecules of mgcl2 is 1/95.11= 0.010514
or total moles in 312 gm of mgcl2 is
0.010514*312
=3.280368 m
Synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called Hebbian Synapse.
<h3>What is Synapse?</h3>
A synapse is a component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the target effector cell.
The transfer of nerve impulses from one neuron to another requires synapses.
The synapse contributes to the development of memory. Because of the signaling mechanisms of the receptors, which are activated by neurotransmitters across the synaptic cleft, the connection between the two neurons is strengthened when both neurons are engaged at the same time. The capacity of two interconnected brain circuits is thought to influence how well memories are stored. Long-term potentiation is the name for this process of synapse strengthening.

C. Dinosaur footprint as it is the only body part that is stated in the choices.
Hope this helps :)
The macromolecules broken down by following enzymes are:
- Nuclease: Nucleotides
- Sucrase: Sucrose
- Lipase: Lipids
- Pepsin: Peptides
Enzymes are the biological catalysts. They function to catalyze the chemical reactions inside any living organism. These enzymes act upon certain molecules called substrates, carry out the reaction in an accelerated manner and then form the product.
Nucleotides are the molecules involved in the formation of genetic material like DNA and RNA. A nucleotide itself is composed of three components: a pentose sugar, a nitrogenous base and a phosphate group. The pentose sugar is different for DNA and RNA. For DNA, it is deoxyribose sugar, whereas for RNA it is ribose sugar.
