Answer:
I believe the answer is Carbon Dioxide.
Explanation:
Answer: The correct answer is B) 23 in males.
In human beings, 23rd pair of chromosome, which is also called sex chromosomes is different amongst males.
It is XY in males whereas it is same in females that is XX.
23rd is the only homologous pair that is different in males as the presence of Y chromosomes determines the male sex. Chromosome pair 1- 22 are same in both males and females and are called autosomes.
Answer:
d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.
Explanation:
The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.

Answer:
Endothermic reaction
Explanation:
An endothermic reaction is that reaction that involves the absorption or use of energy in order to occur. That is, endothermic reactions are energy-consuming. On the contrary, an exothermic reaction releases energy into the surrounding environment.
Breaking a chemical bond requires energy, hence, it is an endothermic process while forming a bond releases energy, hence, an exothermic process. Since a chemical reaction involves breaking and forming bonds, the reaction is overally termed endothermic or exothermic depending on whether more energy is used or released respectively.
In this question, a substance is broken down into its atomic particles when it dissolves in water. In order to break this substance down into atom, the bonds holding each molecule must be broken, hence, energy will be utilized making this an ENDOTHERMIC REACTION.
