Answer:
Option C, stays the same
Explanation:
Heat flow by vibrating the molecules in any medium. Therefore, some medium is essential for heat transfer and hence no heat flows across an insulated vacuum can. Without any medium, heat transfer is stopped which means that neither the heat from outside environment can flow into the can nor it can flow from the can into the external environment.
Hence, the heat contained within the can shall remain the same.
Thus, option C is correct
Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.
Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.
There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.

Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

B) lysosome
C) endoplasmic reticulum
D) nucleus
The Golgi apparatus is the organelle that modifies, packages and sorts proteins for secretion or use within the cell. It processes proteins produced in the endoplasmic reticulum and is involved in their delivery.
The organelle that modifies, packages, and sorts proteins for secretion or use within the cell is the Golgi apparatus. This cellular structure is key in the processing of proteins produced in the endoplasmic reticulum. Proteins are transported from the endoplasmic reticulum to the Golgi apparatus, where they are modified (such as by the addition of carbohydrates to form glycoproteins), packaged into vesicles, and sorted for delivery either to other parts of the cell or to the cell membrane for secretion.

Nondisjunction is the failure of a pair of chromosomes to separate (to disjoin) during cell division (meiosis). When this happens ( in anaphase I of meiosis) two out of the four new daughter cells produced from a parent cell will have an extra copy of one chromosome and the other two daughter cells will end up missing that chromosome.
Most of the time when fertilization involves gametes with an abnormal number of chromosomes, the resulting cell does not survive to produce a new individual. However there are some cases where the individuals survive and such, when they are born end up having a syndrome caused by too many or too few chromosomes. An example is Turners syndrome caused by too few chromosomes (monosomy x) , and Down syndrome caused by too many chromosomes (trisomy 21).
Answer:
Nondisjunction is the failure of a pair of chromosomes to separate during meiosis.
Explanation:
B. absorption of nutrients
C. breaking down complex carbohydrates
D. removing water from undigested waste
The main function of the large intestine is to remove water from undigested waste. Therefore, the correct answer is option d.
The large intestine, also known as the colon, plays a crucial role in the final stages of the digestive process. Its primary functions include:
The large intestine does not play a significant role in the digestion of proteins, absorption of nutrients (the majority of nutrient absorption occurs in the small intestine), or the breakdown of complex carbohydrates (most carbohydrate digestion occurs in the small intestine as well). Its primary functions are related to water absorption, feces formation, and the maintenance of a healthy gut microbiota.
Therefore, the correct answer is option d.
