Answer and Explanation:

The main purpose of mitosis is to certify that daughter cells must get the same genetic info, which is transferred in replicated chromosomes. In order to fulfill this objective, cells employ a microtubule-based molecular machine named a spindle. Chromosomes attach to the spindle through kinetochores and separate macromolecular associations that exist at the chromosome centromere. On every single chromosome, two kinetochores must assign to the contrasting spindle poles. Microtubules shrink and grow until steadied and captured by a kinetochore. In diploid human cells, mitosis takes fewer than 30 minutes. This inconsistency suggests that other mechanisms arrange chromosomes to the high-density microtubules areas and help mitotic spindle association by guiding microtubules' growth toward kinetochores, in mitosis, spindle forms in 3-D space. The spatial departure of replicated centrosomes determines the orientation and length of the spindle. This separation might take place during prometaphase or prophase.

Which of the following fat-soluble vitamins is an antioxidant necessary for synthesizing visual pigments, can be found in butter
liubo4ka [24]

The correct answer is B. Vitamin A.

Vitamin A (retinol, retinoic acid) is a fat-soluble vitamin important for vision, growth, cell division, reproduction and immunity. It also has antioxidant properties.

Vitamin A is present in many foods, such as spinach, dairy products and liver. Other sources are foods rich in beta-carotene, such as leafy vegetables, carrots and cantaloupe. Your body transforms beta-carotene into vitamin A.

There are two dofferent types of vitamin A. The first type, preformed vitamin A, it is found in beef, poultry, fish and dairy products. The second type, provitamin A, is found in fruits,vegetables and other products of vegetable origin. The most common type of provitamin A present in foods and dietary supplements is beta-carotene.

Not consuming enough vitamin A, can cause diseases (which can be avioded with a good diet). Vitamin A plays a very important role in vision. On the one hand, it is essential for the production of the pigment consumed by photoreceptors responsible for vision in darkness. Therefore, low levels of vitamin A lead to night blindness.

How many atoms? * PbSO4​
umka21 [38]

PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.

The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small.

Protons, which have a positive charge, make up the majority of it, while neutrons, which have no charge, form the remainder. All regular, naturally occurring atoms have protons, neutrons, and electrons that orbit them because they are heavy particles.

A sample's mass in grams should be divided by the periodic table's amu atomic mass, and the result should be multiplied by 6.02 x 1023, or Avogadro's number, to determine how many atoms are there. So, PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
