Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,
- All organism are composed of one or more cells
- The cell is the structural and functional unit of life
- It is a de novo structure, that means it COULD arise from non living thing which was incorrect.
It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,
- Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.
Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

- <u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
- <u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
- <u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path
These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

The answer to this question would be: Brain Natriuretic Peptide(BNP) and or Atrial Natriuretic Peptide(ANP)
Both BNP and ANP can be found in heart tissue. But BNP is more frequently used because its level is higher, thus the laboratory result could be better. Both BNP and ANP has diuretic, natriuretic and antihypertensive effect that can counter the fluid overload in congestive heart failure. That is why they are secreted when the cells are stretched.
The statement that "A clustering appointment type is when patients with similar problems are booked consecutively on the same day" is true. Clustering is type of appointmnet scheduling. In this type of scheduling patients with similar problems are booked consecutively. A block of time is set aside for particular types of cases.
Explanation:
As we know that different versions of the gene are called as the alleles. Allele is the various sequence of DNA (deoxyribonucleic acid) or alleles are known to be different forms of the genes, which can be seen at the same locus on the homologous chromosomes. Let us know assume that gene Tyx has two alleles in it, which represents the two forms of expression having same character. i.e. Tallness and Dwarfness TT(tall), Tt(tall), tt(dwarf). In the given question, the version
(a) TT, where alleles exist in the homozygous dominant conditions,
(b) Tt, where alleles exist in the heterozygous dominant condition
(c) tt, where alleles exist in homozygous recessive condition. Therefore, it might follow autosomal dominant inheritance, or autosomal recessive inheritance or incomplete dominance etc.
