16. ) A ___ is the structure that contains the DNA of the cell.
a.) centrosome
b.) chromosome
c.) centromere
d.) vacuole
e.) centriole
Answer:
the closest answer is b.
Explanation:
The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA.
Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. Thus, option B is correct.
What is the role of chromosomes?DNA, the cell's genetic material, is kept in the nucleus. In the nucleus, DNA is often found wrapped up and linked to a variety of histone proteins in a structure called chromatin that is loosely contained.
Chromatin coils tightly and condenses to produce chromosomes just before a cell divides. A DNA molecule called a chromosome is where an organism's genetic code is located.
When a cell is not dividing, chromosomes cannot be seen in the nucleus, not even under a microscope.
Therefore, a chromosome is the structure that contains the DNA of the cell.

Elements in the same period have the same ________________________.
Answer:
Elements in the same period all have the same number of valence electrons.
Explanation:
"Elements present in horizontal rows are called as periods so elements belonging to the same period have same number of shell as the electrons are added in the same shell of the element."
Answer:
All of the elements in a period have the same number of atomic orbitals.
Explanation:
For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.

how would a drug that increases sensitivity of cells to insulin help restore blood glucose homeostasis?
Answer:
Explanation:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

Which of the following is a chemical property of iron?
A. Iron corrodes in moist air.
B. Iron is soft when pure.
C. Iron melts at 1808 K.
D. Iron's density = 7.874 g/cm3
Answer:
A
Explanation:
Iron corrodes in moist air. When iron gets exposed to air, it reacts with oxygen molecules to form rust. Rust degrades the quality of iron. Therefore, methods of protection from rusting like, Barf's protection, Sacrificial protection etc. are carried out.
Iron corrodes in moist air is a chemical property of iron. Hence the correct option is A.
A chemical property of iron is its ability to corrode in moist air. Corrosion is a chemical reaction that occurs when iron reacts with oxygen and moisture in the air, resulting in the formation of iron oxide, commonly known as rust. This chemical property of iron is due to its reactivity with oxygen and can lead to the degradation and weakening of iron-based materials over time.
Corrosion is a chemical process that involves the reaction of a metal with its environment, typically in the presence of moisture or oxygen. In the case of iron, when it comes into contact with moist air, it undergoes a chemical reaction known as oxidation. This reaction causes the formation of iron oxide, commonly known as rust.
The corrosion process begins when iron reacts with oxygen in the air, a process called oxidation. This reaction leads to the formation of iron(III) oxide, which is commonly seen as the reddish-brown coating known as rust. The presence of moisture accelerates the corrosion process by providing the necessary medium for the reaction to occur.
Hence the correct option is A.

What is the answer for 25
Answer:
When a catalyst is present in a biochemical reaction, what is not expected is that the reaction requires more energy than normal (option b).
Explanation:
A catalyst is a substance used to facilitate a chemical reaction, decreasing the reaction time. Unlike a reagent, the catalyst retains the same amount of mass at the end of the reaction.
In a biochemical reaction, the use of a catalyst not only accelerates the reaction, but also decreases the amount of energy required by the process. An example of a biological catalyst is enzymes, specialized proteins that facilitate metabolic reactions.
The other options can be expected with the use of a catalyst, due to:
a. One of the functions of the catalyst is to decrease the amount of energy needed in a reaction.
c. Catalysts are substrate specific.
d. Catalysts work in a specific pH range.
