Answer:Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.

Explanation:

The inner core of Earth is a solid which has a higher temperature and a higher pressure than the outer core of the planet. Thus, the correct option is C.

Scientists have discovered that the outer core of Earth must be liquid because of the S waves, which do not pass through it, whereas the P waves do pass through it. The behavior of P and S waves indicates that the inner core of Earth is solid. The speed of the seismic waves also depends on the density of the materials by which the waves are moving.

The pressure of the inner core is nearly 3.6 million atmosphere and the temperature of the inner core is far above the melting point of iron element. However, the inner core is solid. The inner core's intense pressure and temperature than the rest of the planet prevents the iron from melting.

Therefore, the correct option is C.

Explanation: my teacher gave me work like this

Answer:

Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Answer: Detrivore

Explanation: Detritivores are a smaller, narrower branch of decomposers that break down dead organic matter by consuming it, like worms. Scavengers, on the other hand, only eat some of the dead animal, but cannot break down the entire carcass, like the bones and feathers (I know that's not the question, but it may help to know the difference). Carnivores are animals that only eat the flesh (meat) of other animals, like a blue whale, which feeds on krill. Herbivores only eat plants, or herbs, like zebras. Omnivores, like humans in general, eat both plants and animals.

Answer:

The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

Explanation:

Because the gymnosperm germinates

The oceanic plate is forced down into the mantle in a process known as "subduction." As the oceanic plate descends, it is forced into higher temperature environments. ... This partial melting produces magma chambers above the subducting oceanic plate.

Answer: c

Explanation:

Answer:

In the first stage of sexual reproduction, "meiosis", the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During "fertilisation", haploid gametes come together to form a diploid zygote, and the original number of chromosomes is rest

Explanation:

Answer:

meiosis

Explanation:

During Neolithic revolution first domesticated plants and animals began. Thus, option B is correct.

Thousands of years before humans survived on hunting and gathering practices before crops were developed. Hunter gathers were highly migratory and mobile, lived in small tribes. They were highly depended upon what environment could provide each season.

The first agricultural revolution began called as Neolithic revolution, which helped to form lager populations by changing lifestyle of hunting into agriculture and settlement.

Therefore,  Neolithic revolution is the period when humans first domesticated plants and animals.

DNA vaccines consist of DNA vectors or plasmids (small double-stranded DNA rings originally derived from bacteria, but unable to cause infection) into which the genes encoding one or more immunizing proteins of the infectious agent have been inserted causing the disease to be prevented.

Explanation:

Vectors are the functional unit of naked DNA vaccines. Genes that encode the proteins of interest and are of bacterial origin are inserted into these vectors. Bacterial plasmids are circular DNA molecules that self-replicate extrachromosomally in bacteria. The genes encoded in these plasmids are under the control of promoters, almost always of viral origin. When a plasmid is introduced into the cell it translocates to the nucleus, where transcription of the transgene begins; the transcripts are then taken to the cytoplasm and translated there. The newly synthesized proteins are degraded in the proteasome to 8-10 amino acid peptides, which are transported to the endoplasmic reticulum. Peptides of high affinity with their respective MHC I molecule stabilize and enter the secretory pathway, thus reaching the cell surface, where they are coupled with the T-lymphocyte receptor (TcR) present on the surface of T lymphocytes cytotoxic drugs (CD8 +) to induce their activation.

Answer:

Direct relationship.

Explanation:

There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.

There is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.

Note the following about Water Clarity and how it affects aquatic life:

Therefore, there is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.
