Answer:
False.
Explanation:
The prokaryotes are smaller in size and has large surface area to volume ratio. This high surface area volume ratio increases the rate of diffusion in case of prokaryotes.
The ratio can be obtained by dividing the surface area to the volume. This signifies that how much surface area is available in comparison the volume of the cell. The large cell has large volume. This means the ratio is inversely proportional to the cell size or volume. Hence, the large cell has small ratio of surface area to volume.
Thus, the correct answer is option (b).
Answer:
A soil profile is a vertical section of soil
Explanation:
transports water and minerals
transports food
produces food through photosynthesis
Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.
Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.
Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways
Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.
Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.
Therefore, the correct options are A, B and C.

Answer:
Explanation:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
Which complementary DNA strand pairs correctly with the strand above?
A. 5’ CTAGCTAG 3’
B. 5’ GATCGATC 3’
C. 5’ CUAGCUAG 3’
D. 5’ CATCGATC 3’
Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.
Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.
This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.
Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.
For instance, a complementary DNA strand will have the nucleotidesequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.
Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

Answer:
A genetic disorder is a disease that is caused by the change in the sequence of DNA. Down Syndrom and Huntington disease are two examples of genetic disorders.
Explanation:
A genetic disorder is a change in the sequence of the DNA that results in a disease or condition. These disorders are caused by the mutation of one or multiple genes, by damage in chromosomes, or by environmental factors.
Down syndrome is a known genetic disorder where there is an extra copy of chromosome 21 instead of the two copies. People with Down Syndrom have intellectual difficulties and a different physical complexion that can lead to some problems.
Huntington disease is a genetic disorder that causes the degeneration of neurons, which brings emotional, cognitive, and movement problems that worsen with time since it is a progressive disease.
