A person might use a floating g stick to see how fast a ricer flows because when you put th e stick in the water,the stick moves with the water and goes as fast as it does, so when you look at how fast the stick is, you know how fast the water is.

Answer:
The correct answer will be-
1. Nucleosomes
2. Chromatin
3. Sister chroamtid
4. Centromere
Explanation:
The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.
The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.
The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
<span>Homologous chromosomes are chromosomes of equal length, size, and of corresponding genetic material. If, during meiosis, these chromosomes divide improperly, when they are re-combined with the opposite sex's portion, they will combine improperly. The unequal distribution of genetic material in reproduction will eventually create what's call an aneuploid germ cell: this germ cell results in dead zygotes, which leads to a miscarriage or spontaneous abortion in about 25 percent of all conceptions. So we see that it is imperative the genetic material of these chromosomes be exactly where it is supposed to be: so that it can combine perfectly with its compliment.</span>
Answer:
b. carbon dioxide
Explanation:
This metabolic pathway is called the Krebs cycle after the scientist who first discovered it in 1937. The Krebs cycle is further broken down by pyruvic acid, obtained in the glycolysis process. The process proceeds in two stages. The first is the degree of decomposition of the bicarbonate residue.
The Krebs cycle is the main metabolic pathway for the breakdown of organic matter and the production of energy in the form of reduced coenzymes, which will then be incorporated into ATP.
