1. Drowning, suffocation and carbon monoxide poisoning can lead to death because they all prevent
oxygen from reaching our cells. Explain how this lack of oxygen can lead to death; be specific about how
this lack of oxygen can affect cellular metabolic processes.
Answer: Lack of energy
Explanation:
Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.
Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.
The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.

Cell organelles are any of a number of organized or specialized structures within a living cell.
What is a cell?A cell may be defined as the fundamental structural and functional unit of living organisms. Each living organism is made of a cell. It is responsible for each metabolic function that is necessary for the survival of living entities.
Inside each living cell, a fluid jelly-like substance known as cytoplasm is filled. This provides an environment for the cell to accomplish all sorts of its task. Within the cytoplasm, a number of various organized or specialized structures are present which are known as Cell organelles.
A cell organelle may be characterized as a small structure in a cell that is surrounded by a membrane and has a specific function.
Therefore, cell organelles are any of a number of organized or specialized structures within a living cell.

please help Most ovens we use at home are powered by electricity or natural gas. These ovens use fossil fuels. Describe why the
energy used by a solar oven is considered a clean source of energy.
Answer:
Explanation:
Clean energy are renewable energy. This are energy from natural sources that are renewed without extra cost. Sun, wind, water are examples of renewable natural resources that helps generate clean energy.
The energy are refer to as clean because, they do not lead to any deposit of gasses that can affect the environment leading to environmental pollution. They have little or no side effects, no combustions or release of gases that are toxic or can deplete the environment as in the case of non- renewable energy.

On which end of a growing polypeptide chain is the next amino acid added?
C-terminal
N-terminal
5'-end
3'-end
Answer:
The correct answer is - C-terminal
Explanation:
Polypeptide chains are nothing but the linked amino acid sequences together which is takes place with the help of mRNA, ribosome, and tRNA in a living cell or organism. Polypeptide chain has two ends with two functional groups a carboxyl group end and an amino group end of the polypeptide chain.
The next amino acid added to the carboxyl group end of the polypeptide chain with the bond known as peptide bond and the reaction known as a condensation reaction and a molecule of water is released.

Dehydration Synthesis B. Induced Fit C. Hydrolysis D. Lock and Key Synthesis
Answer: C. Hydrolysis
Explanation:
In the process of hydrolysis, large complex molecules such as polymers are broken down into smaller, simpler molecules like monomers.
This is done through the use of water. The molecule that neds to be broken down is reacted with water and water then breaks the bonds of the complex molecule. The hydrogen ion in water goes to a molecule of the other reactant and the OH- goes to another molecule.

Answer: Genetics
Explanation: This may sound a little strange, but in order to have animals with certain traits, they must be born with or have in the blood line to have said traits. Even then the traits exhibited may not be hereditary. There is a 50% chance that the genetics that you want the offspring to have, may not occur. When a child is made, this means that the parents donate chromosomes from both sides to give the child some of their looks. This could mean disease, eye color, hair thickness.

Volcanic eruptions occur when magma rises upwards through ___ to reach the ____
Volcanoes eruption when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
When Melting takes place?Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Volcanoes are the large volcanic buildings with long, and generally the conical shape, usually with a small crater on the summit and the steep flanks, that constructed by the interleaving of lava flows and the pyroclastic products emitted by one or more conduits.
Compound volcanoes are present in all regions of the volcanism, but it has in the plate convergence zones, where the tectonic plate subdows plunges toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are the most abundant.
The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.
Therefore, Volcanic eruption when molten rock called magma rises to the surface.

A child is born to parents that both have hypophosphatemic rickets, a disease that is caused by a sex-linked dominant trait. What is the chance that the child will have the disease if the mother is heterozygous for the trait?
75%
50%
25%
100%
Answer:
75%
Explanation:
Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates) or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.
When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.
As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).
This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.
If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.
If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.
