So the answer should be gametogenesis/ meiosis....

Hope that helps!

By: xBrainly

Meiosis or gametogenesis is the process that produce human egg and sperm cell.

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.

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.

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:

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.

Explanation:

The immune response is usually triggered by the presence of the donor's own unique set of HLA proteins, which the recipient's immune system will identify as foreign.

To prevent infection, the immune system launches an attack against foreign invaders when it comes into contact with them. The immune system must be able to distinguish between our own healthy tissues and external invaders in order to avert an attack on our own cells and tissues (autoimmunity).

When the recipient's immune system assaults the donor graft and starts killing the transplanted tissue or organ, graft rejection takes place. The presence of the donor's own distinct collection of HLA proteins, which the recipient's immune system will recognize as alien, typically initiates an immunological response.

Histocompatibility refers to the degree of resemblance among the HLA genes of the donor and recipient; the more suitable the donor and recipient are genetical, the more accepting the recipient's immune system should be of the transplant. There will always be some degree of rejection, though, unless the donor and receiver are genetically identical (such as identical twins).

Therefore, the difference in HLA proteins results in graft rejection.

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.

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.

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.

Answer:

One lives inland, while the other lives in the water.

Explanation:

Amblyrhynchus cristatus is a marine reptile that lives in the Galápagos Islands. This species attracted the attention of Darwin because it is a marine iguana that lives exclusively in the Galapagos and, interestingly, their close relatives inhabit in land, also in the Galápagos Islands. The marine and land iguanas from Galápagos form a phylogenetic clade that is characterized by high diversification levels, which are evidenced by conspicuous phenotypic differences. These species can hybridize with each other, but the offspring are infertile. Recently, it has been shown by using phylogeographic analysis that both species diverged 8-10 million years ago.

Time Period D-Walking

Time Period E- Frightened by a loud Noise

Explanation:

The question is asking you to label the time periods shown with the activity that represents the heart rate of the person.

Your heart rate is lowest when you're sleeping because your body is not exercising or under any stress

When you're walking your heart rate will steadily go up but not as high as running because running requires more work and physical strain than walking

Your brain is under extreme stress when you are startled by a loud noise which causes a spike in heart rate.

Answer:

The answer is a

Explanation:

It is not b because when someone is frighented by a sudden loud noise the heart rate will be very pointy.

Not c either because sleeping makes your heart rate very low.

Not d because waking make your heart rate increase (about 90 beats per minute) but then stay in the same rate.

So probably a because running increases your heart rate at a very big level for a long time but then it drop when you stop.
