Answer:
B: Multiple gene mutations
Explanation:
Mutations can be very small changes, affecting only a few nucleotides or they can be very large, leading to major changes in the structure of chromosomes. Both small and large mutations can affect the behavior of cells. Combinations of mutations in important genes can lead to the development of cancer.
Uncontrolled cell growth phrase best describes the Cancer. So, the correct option is (C).
What is Cancer?
Cancer is a disease which caused when the cells divide uncontrollably and it is spread into surrounding tissues. Cells which are divided uncontrollably they are abnormal in nature and also spread to different parts of the body. These cells may form in the lumps of tissues known as Tumors. They are of two types - Cancerous and Non-Cancerous (benign).
Cancerous tumors spread to the nearby tissues or invade into it. It can travel to different places in the body to form new tumor which is called metastasis. Cancerous tumors are also called malignant tumors. Mots of the cancers occur from the solid tumor but in case of blood cancer, it is not.
It is mainly caused by the alteration of DNA. Genetic changes that cause cancer can occur because
Some errors which occur when the cells divide. Damage to DNA which caused by harmful substances in the environment, such as the chemicals in tobacco, smoke, etc.It can be inherited from the parents.Thus, uncontrolled cell growth phrase best describes the Cancer. So, the correct option is (C).

The question is incomplete, the complete question is;
complete the half reactions for the cell shown here and show the shorthand notation for the cell by dragging labels to the correct position. The electrode on the left is the anode, and the one on the right is the cathode.
in the left side there is a solution of Pbcl2(s) and it contains the elctrode pb and on the right side there is solution of AgCl(S) which contains the electrode Ag. There is inverted glass tube with Kcl (aq) on the left and and Kcl(aq) on the right.
Anode half-reaction:
Blank + 2Cl^- equilibrium arrow yields Blank + 2e^-
Cathode half reaction:
Blank +2e^- equlibriums arrow yields Blank + 2Cl^-
Shorthand notation: Please provide.
Answer:
Explanation:
Let us remember that oxidation occurs at the anode while reduction occurs at the cathode. This will guide our work here. The Pb(s)/Pb^2+(aq) is the anode while the Ag^+(aq)/Ag(s) is the cathode
Anode half-reaction:
Pb(s) + 2Cl^- ⇄ Pb^2+(aq) + 2e^-
Cathode half reaction:
2Ag^+(aq) + 2e^- ⇄ 2Ag(s) + 2Cl^-

What are the products for a single pyruvate molecule in the Krebs Cycle?
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

when do birds use their teeth????
Answer:
to eat worms
Explanation:
Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

Describe how a solid rock in the lower level of the crust could become a molten rock.
PLS HELP I WILL MARK BRAINLIEST
Answer:
The higher the pressure on anything, the hotter it will get. The hotter a rock gets, the more possibility that it will have to melt.
So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure. Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.
The net result is like melting a stick of butter. It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.
Identify the tonicity of the solution surrounding the cell.
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

What other traits are highly variable like human skin color ? List at least three
Answer:
Our lack of body hair and our variable skin color are some of the traits that set us apart from our closest primate relatives. Wavelengths of light are reflected or absorbed by pigment in the skin called melanin. Melanin is synthesized in structures called melanosomes that are produced by cells called melanocytes.
Explanation:
Skin colour varies considerably from person to person and is generally of their characteristics:
By the presence of melanocytes, carotene, Oxygenated haemoglobin, and Blood flow.What type of variable is skin colour?"Skin colour is a classic variable characteristic in humans, and it's thought to be adaptive," Tishkoff said. "Analysis of the genetic root of variation in skin colour sheds light on how adaptive traits evolve, including those that play a role in disease risk."
Thus, the presence of melanocytes, carotene, oxygenated haemoglobin, and blood flow.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

ANSWER ASAP PLEASE. What process occurs after glycolysis if oxygen is still available for cellular respiration?
Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.
What is Kreb's cycle?Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.
In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.
Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.
