Answer:
DNA and ATP 2. proteins and lipids 3. chitin and starch ... Singer proposed the fluid mosaic model of the cell membrane in which the cell membrane consists of a double lipid layer with proteins embedded in it to act as name tags or to aid in movement of larger molecules across the membrane.
Explanation:
Answer:Radiant energy is a form of kinetic energy so it is Kinetic energy .
D oxygen there was no free oxygen on the earth
Answer:
The correct answer would be C. 0.60
It can be calculated with the help of Hardy-Weinberg equation i.e
p² + q² + 2pq = 1
Also, p + q = 1
- where p represents the frequency of dominant allele.
- q represents the frequency of recessive allele.
- p² represents the frequency of homozygous dominant genotype
.
- q² represents the frequency of homozygous recessive genotype
.
- 2pq represents the frequency of heterozygous genotype.
Number of homozygous dominant (YY) = 36
Number of homozygous recessive (yy) = 16
Number of heterozygous dominant (Yy) = 48
Total number of plants = 100
Now, frequency of homozygous dominant (YY) = 36/100 = 0.36
Therefore, p² = 0.36
So, p = √0.36 = 0.60
Hence, frequency of dominant allele (Y) = 0.60
<u>Role of Parenchyma cells-</u>
The two primary jobs of parenchyma cells are food storage and transport.
<u>Parenchyma cells-</u>
Parenchyma cells are cells that are living. These cells also have really thin-walls and a structure that is unspecialized. These cells can therefore perform a variety of functions. Parenchyma cells are present throughout a plant. These are present in the form of tissues which are homogenous. Parenchyma cells are present in both the stem and roots. This is the primary reason these cells are involved with the assimilation of nutrients and food. These cells are also present in the flesh of fruits and in seeds, and in the mesophyll of leaves which is why these cells can store food.
