The statement that is false about phytochemicals is that they are essential nutrients. 
<h3>WHAT ARE 
PHYTOCHEMICALS?</h3>
Phytochemicals are secondary metabolites of plants. Secondary metabolites means that they are secreted by the plants but not needed. 
Phytochemicals possess the following characteristics:
- They are naturally occurring chemicals in plants
- They have health benefits
- They can be found in legumes, nuts, seeds, and grains.
Therefore, the statement that is false about phytochemicals is that they are essential nutrients.

Answer:
Invertebrates share four common traits:
They do not have a backbone. They are multicellular. All the cells have different responsibilities in keeping the animal alive. ... They reproduce by two reproductive cells, or gametes, coming together to produce a new organism of their species.

Answer:
Explanation:
The Genotype of the  woman is XCbXN
The man XNY
 Since the allele for the color blindness is carried on one of the X -chromosomes of the  carrier mother, then  the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal  allele from the  mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal  X allele from the father.
Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes
1. XNY vs XCbXN.Then the one of the  boys will be colorblind  and the one of  girls will be carriers. XNXCb, XNXN, XCbY,XNY  50 %
2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle
Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).
The proportions that will be  the females  since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls  take the defective allele from the mothers and take normal from the father,they will all  be carriers,since the X of the father is normal. 
They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.
 
        
             
        
        
        
An action potential involves the transfer SODIUM and POTASSIUM ions across an axon's membrane.
During depolarization, when the ion channels open, they allow the influx of sodium ions into the cell, thus changing the electro-chemical gradient of the cell, in order to counter balance this, potassium ions will be allowed to flow out of the cell.<span />
