Meiosis or gametogenesis is the process that produce human egg and sperm cell.
What is meiosis?Meiosis is a type of reproduction in which a parent cell divide into four daughter cells that are genetically different from the parent cell. The daughter cells have half number of chromosome of the parent cell.
This process produce the gametes which are the sperm cell and egg cell.
Therefore, Meiosis or gametogenesis is the process that produce human egg and sperm cell.

If everyone on the planet used the same amount of
resources as an average American, what percent of
the Earth would need to be used to support
everyone?
A. 150%
B. 75%
C. 200%
D. 50%
Answer:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
Sowe actually would need like 5 Earths.
So none of the options is matches this, but this may be because this question is about some specific resources and not for the specific energy used. The closest option is 200%

the answer is 150 percent

Minerals have a crystal structure, yet, crystals are relatively rare. What are the reasons for this?
Answer:
What are relatively rare are crystals of a size visible to the naked eye, and also showing most of the faces that reveal the internal symmetry of their atomic pattern.
Explanation:
Being crystalline, i.e. having a regularly repeated three-dimensional atomic pattern, does not mean that a mineral necessarily formed under conditions where it could nucleate (i.e. assemble as the tiny cluster of atoms that is the “seed” of a single crystal) and keep growing large flat faces until a regular shape becomes visible to the observer.
To a crystallographer who can seek proof of internal atomic order by X-ray diffraction, the actual size of a solid made of highly ordered matter is irrelevant. Specific techniques (variants of X-ray diffraction methods, or polarizing microscopy) can reveal that a solid material is made of a single crystal (i.e. a uniform atomic pattern is repeated in the same orientation anywhere throughout the solid) or consists of many crystals (the same pattern occurs, but it is oriented differently in what are considered individual crystals regardless of their individual shape or size).
For precision, a crystallographer or a mineralogist will use terms such as “monocrystalline” (the atomic pattern has a single orientation throughout the entire specimen, regardless of shape and size) and “polycrystalline” (the specimen is an aggregate, or collection, of “domains” or “grains” in which the atomic pattern is in an orientation different from its neighbours).
A perfect single crystal of quartz, broken in several chunks, doesn’t lose its internal atomic pattern, only its external “habit” (the overall shape imparted by the flat faces that grew, layer by layer, along directions controlled by the rate of addition to the atomic pattern). Each individual broken chip of quartz is considered “monocrystalline” by the mineralogist, even if none ofo them is the whole original crystal.
Most igneous and metamorphic rocks are polycrystalline, i.e. entirely made of crystals, often tightly packed and interlocked. You may discern individual grains mostly when light reflects off surfaces exposed by breaking along preferred directions within some minerals, or because grains from different minerals contrast in colour or luster. Few of the grains will have a regular geometric shape, despite each one being a single crystal. In the case of an igneous rock, some of the well-formed crystal are typically minerals who grew early from the still-liquid magma. Most of the other minerals simply filled the remaining space. If an igneous magma was “gassy” or “watery”, those volatiles may have remained trapped in the last stages of crystallization and formed late pockets in which a few crystals of exceptional quality grew from the remaining dilute magma and had the space needed to fully develop perfect faces. In many rocks, it is later fractures that provided an “open space” in which crystals could grow larger and with well-developed faces from hydrothermal fluids (overheated ion-rich waters), for the future delight of collectors.

Which statement is true for photosynthesis? Producers use it. Consumers use it. Scavengers use it. Decomposers use it.
Answer:
A. producers use it
Explanation:
Answer:
A
Explanation:
If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result? Less water would be available on the earth’s surface. Less solar energy would reach the earth’s atmosphere. More oxygen gas would be found in the atmosphere. More carbon dioxide gas would be found in the atmosphere.
Answer:
More carbon dioxide gas would be found in the atmosphere.
Explanation:
Photosynthetic organisms convert carbon dioxide in air to oxygen through photosynthesis, while other non-photosynthetic organisms only consume oxygen and release carbon dioxide through respiration, they do not undergo photosynthesis.
When the number of photosynthetic organisms on the earth decreased drastically, the carbon dioxide released from other non-photosynthetic organisms cannot be converted to oxygen, so carbon dioxide in air accumulates.
How did Griffith help build our understanding of genetics?
O A. He showed that only humans contain DNA.
O B. He showed that cells contain a transforming factor.
O c. He showed that traits cannot be inherited.
O D. He showed that viruses do not contain DNA.
Answer:
B. He showed that cells contain a transforming factor.
Explanation:
Griffith showed that cells contain a transforming factor.
What is Griffith's experiment?He worked on the pneumonia causing bacteria, Streptococcus pneumoniae.He found that this bacteria has two colonies: smooth colonies (S strain) and rough colonies (R strain).When mice were infected with S strain, they die from pneumonia whereas mice infected with R strain will survive as they do not develop pneumonia.The bacteria was the killed by heating. When mice were infected with heat-killed S strain, they survive as they do not develop pneumonia whereas when mice were infected with heat-killed S strain + live R strain, they die.It was observed that the R strain has been transformed by heat-killed S strain.It states that some "transforming principle" has enabled heat-killed S strain to transfer its virulent properties to R strain.Hence, the correct option is B. He showed that cells contain a transforming factor.

11. Which of the following is not a cause of cell necrosis?
Infection
Blood clot
Injury
Perfusion
Infection, blood clot, and injury all are the causes of cell necrosis except perfusion. Thus, the correct option is D.
Cell Necrosis is the death of the cells which are present in the body tissues. While the dead body tissue can be removed, it cannot be brought back to the good health.
The necrotic tissue appears as white and friable cells, like the clumped cheese. Dead cells in the body disintegrate however are not completely digested by lysosomes, thus leaving granular particles. Microscopic examination of the dead cells show amorphous granular debris that is enclosed within a distinctive inflammatory border.
Cell Necrosis can occur due to different causes such as injury, infections or diseases. Lack of blood flow to body tissues and extreme environmental conditions.
Therefore, the correct option is D.

Answer:What traits would orchids have if the MADS-box genes were not duplicated?
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?
Explanation: The example given by Plato
If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
What is Genetic mutations?The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.
For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.
The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.
Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

What is the benefit of using a shortcut in a reaction between two chemicals? A shortcut would ensure a safer reaction. A shortcut may provide a faster reaction. A reaction with a shortcut would yield more chemical output. A reaction with a shortcut would require less chemical input.
Answer:
A shortcut may provide a faster reaction
Explanation:
Chemical reactions occur in a particular manner and speed if allowed to occur normally. However, shortcuts can be used for the essence of making the reaction proceed much faster than it naturally would. Catalysts are the substances used to provide these shortcuts.
A catalyst is a substance that increases the rate at which a chemical reaction occurs without being chemically used up in the reaction. A catalyst speedens up the chemical reaction by decreasing the activation energy. The activation energy is that energy needed for a chemical reaction to kick start. The higher the activation energy, the slower the reaction proceeds.
A catalyst, thus, creates a shortcut by lowering the activation energy of the chemical reaction, allowing it to proceed faster than when a catalyst is not used.
