If a cell with 42 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?
Answer:
42
Explanation:
If a cell has 42 pairs of chromosomes (n = 42), it has 84 chromosomes (2n = 84). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 84 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 42 chromosomes.
A simple example is↓
The parent cell of 10 chromosomes will end up becoming two daughter cells that each have a copy of those 10 chromosomes.
The important fact about mitosis is that the daughter cells are identical to the parent cell. The daughter cells will have the same number of chromosomes as the parent cell.
If a cell with 42 chromosomes undergoes mitosis, the equal 42 chromosomes will each daughter cell have.
What is Mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
Before a cell divides it undergoes DNA replication. As a cell enters mitosis, double-stranded chromosomes fuse from the replicated DNA. A cell having 42 chromosomes will have 42 double-stranded chromosomes entering mitosis. Upon completion of cell division, each daughter cell will receive 42 single-stranded chromosomes, as double-stranded chromosomes are pulled apart during mitosis.
Therefore, if a cell with 42 chromosomes undergoes mitosis, the equal 42 chromosomes will each daughter cell have.

What are 2 functions of carbohydrates?
A. Carbohydrates are used to store energy and store information in living things.
B. Carbohydrates are used to store energy and provide structure/support in living things.
Answer:
In Short The correct answer is B...
Explanation:
Here are most of the functions of carbohydrates altogether:
Provide instant energy to the body. :This appears to be the primary function of carbohydrates in the body. ...
Reserve food: Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
Carbohydrates form other biomolecules.
Detoxification of the body by metabolism
Carbohydrates participate as reaction intermediates in some vital reactions. This function of carbohydrates is seen extensively in various cellular reaction.
For example, one of the vitamins, Vitamin B2 also called Riboflavin has a ribose sugar moiety. This ribose is a four carbon type of carbohydrate monomer by its chemical structure. It is involved in vital reactions at the organ and cellular level. Similarly, carbohydrates are also chemical constituents of many hormones, vitamins, enzymes, etc.
Carbohydrates form a part of DNA and RNA in the form of deoxyribose and ribose sugars. These are five carbon monosaccharides formed form heptulose sugars by the pseudo-heptulose pathway.
They are constituents of all the cellular organelles. Carbohydrates are also components of cell organelles like the cell membrane, mitochondria, nucleus, endoplasmic reticulum, etc. They provide structural integrity, mechanical strength in combination with proteins and lipids. They help make up the body mass by being included in all the parts of the cell and tissues. For example, in cell membranes, there are two constituents, i.e., glycolipid layer and glycoprotein layer. Here the term “glyco” is a carbohydrate.
8. Transport of oxygen: Glucose is taken by red blood cells. These are the types of blood cells which lack mitochondria and other cell organelles required for producing energy. In such a case, the ATP is produced by a non-oxidative pathway with the end product as lactose and ATP.
This energy thus produced is necessary for hemoglobin to bind to oxygen molecules. These bound oxygen molecules are transferred from lungs to the different tissues.
9. Aid in gut motility: Our diet has carbohydrates in greater proportions because, it aids in bowel movement. When you suffer from constipation, doctors first prescribe you bran and other carbohydrate material like Ispaghula. The carbohydrates in these material is in the form of fibrous material. When they are ingested, their material absorbs water in the guts, swells and increases the load.
This load is useful to increase intestinal motility and expulsion of waste (feces). Thus carbohydrates help clear gut and prevent constipation. Hence, when you feel constipated, have banana fruit and notice the change.
They play a role in other physiological roles. Since they are components of many bio-molecules, they have further roles in body physiology. They have a role in blood clotting, immunity, fertilization. Thus they take part in many physiological reactions.
Answer:
B. Carbohydrates are used to store energy and provide structure/support in living things.
Explanation:
The two functions of carbohydrates are to store energy and provide structure/support in living things.

Explanation: Climate change is causing the extinctions of species. But some species will have better chances of survive-al because they were created that way. So, humans for example will have a good chance of survive-al despite of climate change, because we are always innovating and changing, while most plants and animals, are used to one type of climate or region. Although there some cases of plants and animals that can adapt to any struggles of climate.

The cell grows in which phases?
A. G1, S, and G2
B. G1 and S only
C. G2 and S only
D. G1 and G2 only
Answer:
D. G1 and G2 only
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Answer:
D. G1 and G2 only
Explanation:
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.
David was sitting in his hotel room reading a book, when he heard a knock at the door, and the sound of someone trying the door handle. He opened the door,
where he saw a man whom he had never seen before. The man said, "I'm terribly sorry... I thought this was my room. Wrong floor, I guess. He then walked
off down the hall toward the elevator. David went back into his room, thought about what had just happened, and then phoned the front desk, suggesting they
call the police, since the man at the door had obviously been a thief.
Why was David so sure the man had been a thief?
Answer:
if he thought that it was his own room, he wouldn't have knocked (because people don't knock on their own rooms)

Explanation:
what changes were most likely caused by a shift in earth's continents?
Answer:
The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.
Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:
<p><strong>Fig 7.15.</strong> Diagram of the motion of plates</p>
Collision: when two continental plates are shoved together
Subduction: when one plate plunges beneath another (Fig. 7.15)
Spreading: when two plates are pushed apart (Fig. 7.15)
Transform faulting: when two plates slide past each othe
