Help!! Why do geologists radioactive/carbon dating determine absolute age? (i need this quickly!)
Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.

Adenine and Thymine are examples of nitrogenous bases in a nucleotide.
What is a nucleotide base?A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.
Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group.
The two classes of nitrogenous bases are purines and pyrimidines and they are as follows;

Why does cell size need to be limited?
Where does the DNA come from that is in the parent cell?
Answer:
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

What will happen to the pressure in the brain if water moves into it from the blood?
Answer:
A sudden increase in the pressure inside a person's skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery
Explanation:
A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.
What is brain?The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath.
It is possible for patients with elevated ICP to fully recover with prompt treatment.
Therefore, A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.

How does deforestation affect coral reefs?
Answer: When the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs. That runoff adds nutrients to the ocean water.
Explanation: Basically, when this occurs, the roots are no longer attached to the soil, letting all the nutrients get ruined in the ocean water instead of feeding plants/animals/trees.

How is the cell division of cancer cells like these misregulated?
Select all that apply.
Such cells are not inhibited by density.
Such cells can divide in the absence of growth factors.
Such cells skip the G1 phase of the cell cycle.
Such cells do not require anchorage to a surface in order to divide.
Such cells do not respond to signals that normally trigger apoptosis.
Such cells do not need enzymes for DNA replication.
Cancer is due to irregularities in cell division that are caused by mutations in cancerous cells. These mutations inhibit apoptosis and favor cell division. Among the options, the correct ones are 1, 2, 4, and 5.
------------------------------------------
Cancer is the result of irregular cell division.
Its development and progression are closely related to changes in the cell cycle regulator factors.
Cancerous cells
• Divide when they should not do it ⇒ overactivity of the positive cell division regulators.
• Do not stop dividing when they should ⇒ reduction in the activity of cell division inhibitors
• Do not die when they should ⇒ loss of the apoptotic capability
• Leave the area where they are growing ad travel to other parts of the body ⇒ metastasis
Normal cells divide and die during a programmed period.
When a normal cell mutates or suffers from any alterations that can not be repaired, it automatically activates its apoptotic process.
However, cancerous cells lose the capability of dying and their reproductive inhibition, so they keep growing and dividing with no limits.
The unlimited division occurs because mutations in cancerous cells influence the cell cycle by favoring proliferation and inhibiting senescence and apoptosis.
These cells do not depend on external growth factors or other protein signals to divide.
Cancerous cells can release their own growth factor and even influence neighbor cells to produce and release these substances.
Cell division is constant even when there is no space.
Sometimes over multiplication creates tumors that might affect healthy neighbor cells and the tissue itself.
Among the options,
1) Such cells are not inhibited by density. CORRECT
2) Such cells can divide in the absence of growth factors. CORRECT
3) Such cells skip the G1 phase of the cell cycle. INCORRECT
4) Such cells do not require anchorage to a surface in order to divide. CORRECT
5) Such cells do not respond to signals that normally trigger apoptosis. CORRECT
6) Such cells do not need enzymes for DNA replication. INCORRECT

Cancer cells can divide in the absence of growth factors. Cancer cells do not require anchorage to a surface in order to divide. Cancer cells do not respond to signals that normally trigger apoptosis.
Cancer cells can multiply without any growth factors whereas normal cells will not divide without the addition of growth factors. Cancer and tumor cells are less dependent on anchorage. They are free to proliferate, and invade tissues. A normal cell that have damaged DNA will undergo apoptosis while on the other hand, cancer cell with unfixable DNA will not undergo apoptosis and will continue multiplication.

He knew his pursuer was coming; he heard the padding sound of feet on the soft earth, and the night breeze brought him the perfume of the general's cigarette. It seemed to Rainsford that the general was coming with unusual swiftness; he was not feeling his way along, foot by foot. Rainsford, crouching there, could not see the general, nor could he see the pit. He lived a year in a minute.

What is cellular respiration ?
A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.
