Which components of animal plasma membranes reduces the permeability of the membrane to most biological molecules?
jarptica [38.1K]

Cholesterol

The animal plasma membrane is a layer of phospholipids that is entwined with cholesterol and proteins. Cholesterol makes up a small part of the cell membrane's mass and it is present in every cell of the body. Cholesterol maintains the integrity of the cell membrane. It assists in the immobilization of the outer surface of the cell membrane and it reduces the permeability of the membrane to most biological molecules. Cholesterol also perform roles in cell signaling, maintaining fluidity  and protecting important proteins in the membrane.

Label the figure below. Word bank: leading strand, lagging strand, DNA
Natalija [7]

Answer:

DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.

Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.

The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.

The points where DNA is currently unwinding are called replication forks.

Some inbred strains of the weedy plant Arabidopsis thaliana flower early in the growing season, but other strains flower at late
RoseWind [281]

Answer:

a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.  

b. The genotype of all the four plants are:  

1st plant = Ll

2nd plant = ll

3rd plant = LL

4th plant = Ll

c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).  

In case if the 2nd plant is self-fertilized, the expected progeny will be only early.  

In case if the 3rd plant is self-fertilized, the expected progeny will be only late.  

In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).

How are the names of binary ionic compounds determined?
Alexandra [31]
Naming ionic compounds<span> with transition metals isn't too hard either. They are</span>named<span> like the </span>binary compounds<span>, with the cation first, then the anion with -ide added to it, but you have to take into account the variations of the metal </span>ions<span>. You do this by adding Roman numerals in parenthesis to the cation.</span>
