Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This keeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.
Normal cells VS mutant cellsNormal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.
While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

Answer:
Look down!!! ;)
Explanation:
In a human karyotype, autosomes or “body chromosomes” (all of the non–sex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). However, chromosome 21 is actually shorter than chromosome 22.

Radioactive dating technique
To confirm the ages obtained with magnetic records, and get an absolute age of the seafloor, scientists use the radioactive dating technique. When the lava solidifies at the ridges to form the new seafloor, radioactive elements coming from the mantle are trapped in it.
How does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

Drag each image to indicate whether it shows point source pollution or non-point source pollution
Answer: The first and the last are point source and the second and third are non-point source.
Explanation: I got these right on the quiz.
The first image and the last image are point source pollution while the second and third images represent non point source pollution.
A point source pollution refers to a pollution that is emerging from a particular point such as from a pipe. It is traceable to a given source. The non - point source pollution is not traceable to any particular source.
In the image as shown, the first image and the last image are point source pollution while the second and third images represent non point source pollution.

How did the invention of the microscope contribute to knowledge about 1p living things?
Answer:
It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.

Because biological systems are generally held at constant temperature and pressure, it is possible to predict the direction of a chemical reaction by measuring which of the following?
a. ATP concentration
b. Enthalpy
c. Entropy
d. Free energy
Because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.
What role does free energy play in the biological system?In a biological system, the free energy is very significant, where the free energy is the amount of energy that is needed by the cells of the body to perform the function, and the negative free energy indicates that the reaction is exothermic and this energy can be used for other processes. The process where free energy is needed, known as endothermic process, must be completed when there is positive free energy.
Hence, because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

The division of the cytoplasm, which follows Mitosis, is called...
Answer:
Cytokinesis,
Explanation:
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.
The division of the cytoplasm, which follows Mitosis, is called Cytokinesis. This is further explained below.
What is Mitosis?Generally, Mitosis is simply defined as a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.
In conclusion, Cytokinesis is simply defined as the division of the cytoplasm that occurs after mitosis to produce two daughter cells.
