<h2>Phenotype probability</h2>
Explanation:
- In the given question,let say A is dominant allele and a is recessive allele
- Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
- When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%
YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.

Cells at the completion of meiosis compare with cells that are in prophase of meiosis I is (A) The cells have half the number of chromosomes and half the amount of DNA.
The correct option is (A).
- The cells produced at the end of meosis cell division have half the number of chromosomes (termed as Haploid), so they will have half the number of chromosomes but same DNA as that of the parent cell as DNA divides and makes a copy of the parent cell DNA.
- Meiosis is a form of cell division of germ cells that creates gametes such as sperm or egg cells in sexually reproducing animals. It consists of two rounds of division that result in four cells with just one copy of each chromosome (haploid). Prior to division, genetic material from the paternal and maternal copies of each chromosome is crossed across, resulting in novel code combinations on each chromosome.
- During fertilisation, the haploid cells generated by meiosis from a male and female will unite to form a zygote, a cell with two copies of each chromosome.

Answer:
Cytoskeleton
Explanation:
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement. Cytoskeleton is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition including microtubules, actin filaments and intermediate filaments.
