Chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow.
What characteristic do these cels most likely share with cancerous cells?
O They form tumors.
O They spread through the blood.
• They divide rapidly.
O They contain a mutation.
A
Answer:
They divide rapidly
Explanation:
Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.

Use the above facts and rules to answer the following questions. Also provide the Prolog query that would resolve the answer. What swims? Do lizards have scales? What eats fish? What do things with scales eat? Add the following rules to the program: Reptiles are things with scales that slither or crawl. Fish are things with scales that swim and eat fish. Insects fly and are eaten by reptiles and bugs.
Answer:
Fish can swim.
Explanation:
Fish are cold blooded organisms that has the ability to live and swims in the water or aquatic ecosystem. Yes, lizards have scales on their bodies because lizards belongs to the reptile family. Organism such as octopuses, squid, sharks, grizzly bears, snakes, turtles, and sea gulls feed on fish. Reptiles are the organisms whose body covers with scales.
A old Cell is called what?
1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.
Answer:
1. Stamen and pistil
2. Pollen, microspore
Explanation:
The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).
The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

After being hunted to near extinction, wolves were reintroduced to Yellowstone National
Park in 1995. After two years, the population of wolves increased rapidly until 2009.
After 2009, the population decreased slightly and has remained at an average of 93
wolves. Which type of growth curve describes the Yellowstone wolves?
A. population density curve
B. exponential growth curve
C. bell curve
D. logistic growth curve
Answer: B: exponential growth curve
Explanation: An exponential growth curve is J-shaped. Exponential growth is more common in R-selected species, which have a short life span and a high rate of reproduction. Yellowstone National Park has 124 wolves living in it.

Answer:
I would have to say recharge of the aquifer by using ground water after some precipitation.
Explanation:
Melting snow or rain increases ground water that percolates down to replenish the aquifer.
Elevation changes causes the aquifer to flow up in low spots/springs on the surface. And the cycle repeats through evaporation and plant respiration.

What structure provide shape and support for the cell?
A.Chloroplast
B.Mitochondria
C. cell Wall
D.Golgi bodies
The cell wall provides shape and support for the cell. Therefore, option (C) is correct.
What is cell wall?In the cells of plants, fungi, and some bacteria, the cell wall is a strong structure that encloses the cell membrane. It has a solid and strong structure because it is formed of chitin, which is found in fungi and cellulose in plants. The cell wall supports it mechanically, shields it from harm, and aids in keeping its shape. Moreover, it stops the cell from bursting or collapsing under pressure, which is crucial for plant cells because they must maintain turgor pressure in order to function properly.
Animal cells, on the other hand, lack a cell wall and instead contain a cytoskeleton formed of protein fibers that gives them stability and shape. Organelles that perform photosynthesis include chloroplasts, mitochondria, and golgi bodies, which also produce energy and process and transport proteins inside of cells.

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.
The number of guanines in the double-stranded DNA is 4.
In the DNA, the base pairing occurs as:
The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule. Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.
Therefore, the guanine in the nucleotides will be 4.

What is a Chemical reaction?A chemical reaction may be defined as a mechanism that significantly directs the chemical transformation of one set of chemical substances or molecules to another. This process of chemical transformation utilizes numerous catalysts to enhance the rate of reaction.
The amount or number of chemical substances or molecules that are present before the progression of reaction are known as reactants.
While after the successful progression or completion of a specific chemical reaction such reactants are performed into another, these substances or molecules are known as products.
Both the molecules of reactants and products possess some sorts of chemical identity in order to distinguisg from each other.
