What are nutrients?--A substance that provides nourishment essential for growth and the maintenance of life.

What happens if you don't get nutrients?​--A nutritional deficiency occurs when the body doesn't absorb or get from food the necessary amount of a nutrient. Deficiencies can lead to a variety of health problems. These can include digestion problems, skin disorders, stunted or defective bone growth, and even dementia.

A substance that provides nourishment essential for the maintenance of life and for growth.

If you do not gain enough nutrients, a nutritional deficiency occurs (when the body doesn't absorb or get from food the necessary amount of a nutrient). Deficiencies can lead to a variety of health problems. These can include digestion problems, skin disorders, stunted or defective bone growth, and even dementia.

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.
lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which  leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase)   that  metabolize activities of  cholinergic   neurotransmitters  e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites  transmits action potential to the  neuromuscular junction is called presynaptic neuron. While  neuron that  transmit action potential away from the neuronal synaptic junction, or from the neuromuscular  junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called  post synaptic  neuron.

The more  negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of  activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to  continuous   excitatory activities  of cholinergic neurotransmitters   on  the receptors at the postsynaptic neuron, and the more  action potential

Describe how a new mRNA transcript is processed before it leaves the nucleus.
Schach [20]

Answer:

removal of introns, addition of 5' cap and 3' tail to mRNA.

Explanation:

The mRNA is processed before it leaves nucleus. The introns are removed and exons are remain in mRNA. This process is called splicing. The 5' end is attached with a cap and 3' is attached with a polyadenylated tail. Thus mRNA is processed with these process before it leaves the nucleus.

How does biomass in a community change as succession proceeds?
fenix001 [56]

A

It increases because the biodiversity of the community in the environment during succession increases.

Explanation:

During primary succession, the nutrients in the rocks are gradually released as pioneer plants help break up the rocks into soil. These nutrients are taken up and more species of plants are able to thrive in the environment including the perennial and biennial plants. These plants provide food and shelter for higher organisms (hence many longer food webs and chains) and this is why biodiversity increases with increased succession until the climax community is reached. Increased biodiversity means increased biomass.
