A scientist is investigating the effects of salinity on fish development in the Atlantic Ocean. He places fertilized fish eggs i

n an aquarium that contains lower salinity than typical Atlantic Ocean water. He observes that the fertilized eggs fail to develop. He concludes that fish eggs do not develop in conditions with low salinity. Why is this an invalid conclusion? The experiment lacks an experimental group. The experiment does not measure any dependent variables. The experiment does not have a group tested in normal salinity. The experiment changes more than one variable at once. i need help ASAP PLEASE

If a lipid bilayer is at least 108 times less permeable to K ions than it is to water, how do the K ions that are needed for man
valina [46]

Answer:

Explanation:

If the lipid bilayer is at least 108 times less permeable to K ions than it is to water, then a way that this much needed ions can get into the cell is through ion channels.

Ion channels are memberane proteins that form pores and they also span across the cell membrane allowing ions to pass through these pores. They act as a passage through which charged ions can pass through. There are three main type: voltage-gated, extracellular ligand-gated, and intracellular ligand-gated ion channels.

Consider the cross between two different pea plants with the following genotypes: PpTt x PpttP (purple flowers) is dominant over
Sonbull [250]

Gametes of the parents would be:

PpTt : PT ; Pt ; pT ; pt

Pptt : Pt ; Pt; pt ; pt


You can do this easily using the FOIL method on each genotype. Just like in math, F stands for first; O stands for outside; I stands for inside; and L stands for last. I'll do one parent genotype and maybe you will understand how this was done:


GENOTYPE: <em>PpTt</em>


<em>F- </em><em>irst of each pair. P and T</em>


P p T t


Gamete: <em>PT</em>


<em>O </em><em>- utside allele of the pair. P and t</em>


P p T t


Gamete: Pt


<em>I - </em><em>inside alleles of the pair. p and T</em>


P p T t


Gamete: pT


<em>L</em><em>-ast or end allele of each pair. p and t</em>


P p T t


Gamete: pt
