Which part of the cell theory do these results most support:

Vlad1618 [11]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\huge\textbf{Cell Theory}$

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.

$\huge\textbf{Question:}$

<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.

In humans, there are four blood types: A, B, AB and O. Each parent can give their offspring one of three blood type alleles, IA

Delvig [45]

Answer: One parent is IAi and the other parent is IBi

Explanation: As this trait is codominant, the child can inherited IA, IB or i.

Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.

How is prophase, metaphase and anaphase of mitosis, meiosis I and meiosis II different or the same?

bulgar [2K]

Answer:

The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.

The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.

Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
