Answer:
Yes,it's clear that bees play a vital role in food production. They are excellent pollinators! Most food crops—including fruits, vegetables, nuts, and seeds—must go through pollination. That's the process of moving tiny pollen cells between plants to help them make seeds.

Explanation:
Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion
Answer:
Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.
Explanation:
When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.
(3) (b) The mean concentration of red blood cells in an adult is 5.5 × 106 cells per mm3 1 mm3 = 0.000001 dm3 Calculate the mean number of red blood cells in 1 dm3 Give your answer in standard form.
Answer:
The correct answer is - 5.5*10^12 cells per dm^3
Explanation:
Given:
The mean concentration of red blood cells in an adult = 5.5 × 10^6
or = 5500 000
1 mm3 = 0.000001 dm^3
Solution:
Then, 1 dm^3 = 1000000 mm^3
(55000000 × 1000000) = 5500,000,000,000
= 5.5 × 10^12
how sclerenchyma tissues are important for plant though they are dead tissue ?
Answer:
Hey friend !!!
The cells of sclerencyma are without nucleus and protoplast....they are dead cells..
They provide mechanical support to organs of the plant body....
Hence they are important for plants....
Answer:
Sclerenchyma tissues are tissues that makes up parts of the plants that are hard. Like the nuts and covering seeds etc, These tissues have a hard thickness providing agent called lignin and lignin makes the cell wall too hard the sometimes the cell contains nothing. This cell mainly provides mechanical support to the plant

which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell
Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.
