Why is it so important for scientists to calculate exact amounts of products used by
Vsevolod [243]

Answer with Explanation:

When it comes to the study of the outer space, <u>astronauts play a vital role in giving people significant information regarding their exploration.</u> Most of the missions last for 6 months in space and this is followed by another mission lasting at the same time or so.

When astronauts travel, <em>they need to bring exact amounts of products that they will be using during their expedition.</em> These products are particularly related to personal items that they need in order to survive. However, <u>these items have to be calculated in terms of their weight, since the space craft can only accommodate a certain amount of mass. </u>

The collective term for the personal items is "Personal Preference Kit" or the "PPK." It is said that an astronaut can only carry up to 20 personal items and the total weight should only be<em> 1.5 pounds. </em>

Thus, this explains the answer.

The diagram represents part of a plant cell. Identify the name of the location in the plant cell
konstantin123 [22]

Answer:

The <u>stroma</u> within the chloroplast

<u />

Explanation:

Chloroplasts are membrane-bound organelles  in plants. They comprise many invaginations of a plasma membrane called a thykaloid membrane. This includes chlorophyll pigments in layers called granum, whereas the internal spaces of the organelle are called lumens. Fluid surrounds the granum, and forms the stroma; here, all metabolic reactions within the chloroplast occur- <u>including CO2 fixation.</u>

Photosynthesis, involves the conversion of energy from photons or light particles and water, starting in the thykaloids; here, the pigments like chlorophyll, which is essential to photosynthesis, reside.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At a basic level mitosis and meiosis are similar processes. However, they have very different outcomes. Which of the following s
Dafna1 [17]

Answer: C. Homologous chromosomes are separated in meiosis but not in mitosis.

Explanation: There are two main types of division that take place in eukaryotic cells, mitosis, and meiosis. Mitosis is the type of division that is used for growth, repair, and replacement of tissues. Therefore it is not necessary that the cells have  different chromosome numbers or are varied genetically in the daughter cells in the case of mitosis.

Meiosis is the division that takes place to form the gametes for sexual reproduction. It is important in the first stages of meiosis I, to introduce variation and to halve the chromosome number.

Chromosomes numbers are halved (from 46 to 23) during meiosis I because the gametes (sperm and egg) come together and fuse during fertilization to form a zygote. When this fusion occurs (23 from the zygote and 23 from the egg), the chromosome number needs to be returned to that of the parent cell (46).

<h2>Genetic variation is introduced during synapsis which only occurs in meiosis, not mitosis. Homologs exchange genetic information during crossing over of synapsis. Entire chromosomes also separate during meiosis I. </h2>

At the end of meiosis, four genetically unique cells are  produced with half the number of chromosomes as the parent cell (23 cromosomes) . After the process of mitosis is completed, two cells genetically identical to each pther are produced and have the same number of chromosomes as the parent cell (46 cromosomes).

Genetic variation is actually important because of changing environmental conditions.
