Deoxyribose + phosphate group + thymine.
This is because anything with ribose is RNA and uracil is in RNA not DNA, all 3 other options have at least 1 of these in.
The cavity which separate or in between the nose and the mouth is the nasal cavity.
The nose and the mouth meet at a junction called the pharnx; option A
<h3>What is nasal cavity?</h3>
The nasal cavity refers to a large, air-filled space above and behind the nose in the middle of the face. It is the cavity which divides the nose and mouth.
However, the nasal septum divides the cavity into two cavities .
- The larynx is the passageway for air between the pharynx above and the trachea below.
- The pharynx carries air, food and fluid down from the nose and mouth.
So therefore, the cavity which separate or in between the nose and the mouth is the nasal cavity.

<span>B, enzymes will denature at that temperature. Sucrase has an optimal temperature of about 37 degrees celsius so 1000 would definitely be too high for them to work.</span>
Answer:
a. The spindle apparatus is present in cells undergoing <u>mitosis and meiosis. </u><u> </u>the spindle is crucial for chromosome sorting.
b. Chromosome replication occurs just prior to <u>mitosis and meiosis I. </u> DNA needs to be copied during S fase to have enough DNA and transfer it to the daughter cells.
c. The cells resulting from <u>mitosis </u>in a haploid cell have a ploidy of n.
Mitosis produces identical cells.
d. The cells resulting from <u>meiosis II </u>in a diploid cell have a ploidy of n. meiosis is the only process that causes chromosome reduction (assuming no errors).
(e). Homologous chromosome pairing regularly occurs during <u>meiosis I.</u> Each daughter cell needs 1 chromosome of each kind
(f). Non-homologous chromosome pairing regularly occurs during <u>none</u>. This is kind of an error.
(g). Physical recombination leading to the production of recombinant progeny classes occurs during <u>Meiosis I </u>
(h). Centromere división occurs during meiosis II and mitosis
(i) Non-sister chromatids are found in the same cell during <u>meiosis II</u>
