PLEASE HELP WILL GIVE BRAINLIST!!!! Write a hypothesis to describe the relationship between earthquakes and tsunamis.
Answer:
Hypothesis: Earthquakes and tsunamis are caused by tectonic plates in the Earth's crust. When the crust moves, they occur, depending on the location of the crust.
Answer:
Most times a earthquake is what causes a tsunami, such as a deep ocean earthquake causing a tsunami to form. Most tsunamis are formed that way because deep ocean earthquakes create so much force.

A) The volcano stops erupting.
B) The lava cools form rock.
C) Lichens grow on the rock
D) The rocks melt back into lava.
Answer:
it is C
Explanation:
Lichens grow on the rock best describes the first stage of ecological succession that will begin the return biotic feed factors to the forest community and return it to a state of equilibrium. So, the correct option is (C).
What is Ecological succession?Ecological succession is the process of change in the species composition of an ecological community over time. This time scale can be decades or more or less.
In this process, the species and habitat mix in an area changes over time. These communities replace each other until a "climax community" – like a mature forest which is reached, or until a disturbance such as fire occurs. Ecological succession is the type of fundamental concept in ecology.
During succession, the area colonized and their populations of some species increase, while the populations of other species decrease and even disappear, Lichens grows on the rock etc.
Thus, Lichens grow on the rock best describes the first stage of ecological succession that will begin the return biotic feed factors to the forest community and return it to a state of equilibrium. So, the correct option is (C).

Choose the correct connective tissue.
1)Bone to bone
2)Muscle to muscle
-ligament
-tendon
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
A tendon is a fibrous connective tissue which attaches muscle to bone.
A ligament is a fibrous connective tissue which attaches bone to bone.
What is tendons and its function?
A tendon is a cord of strong, flexible tissue, similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.
What is ligament and its function?
Ligaments often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together. This ensures that the bones in the joint don't twist too much or move too far apart and become dislocated.

Differentiate the pH conditions of the stomach and intestine and how does it help in the digestion of food.
i will mark u as brainliest if u answer
Answer:
pH of stomach is more acidic ranging from 1.5 to 3.5 meanwhile intestine is more on the neutral side ranging from 6 to 7.4
Explanation:
as far as it is concerned about digestion relation between the two stomach and intestine is that stomach has more acidic pH because most of the the digestion occurs in stomach. the more acidic ,the more quickly food will be broken down to essentials .like an upset stomach as it overdoes the digestion as for the intestine it is mainly responsible for absorption of already digested food..
When the population of ant (prey) increases, what would you predict the population of the ant-lion (predator) would do?

The p53 gene is important to the cell cycle in G1 and G2, and cancer. What happens to the cell cycle when a mutation occurs in the p53 gene?
(please no links!!)
Answer:
PFFT this might help? sorry if not mate
Explanation:
Cell cycle checkpoint controls play a major role in preventing the development of cancer [see Sherr, 1994, for a more detailed discussion]. Major checkpoints occur at the G1 to S phase transition and at the G2 to M phase transitions. Cancer is a genetic disease that arises from defects in growth-promoting oncogenes and growth-suppressing tumor suppressor genes. The p53 tumor suppressor protein plays a role in both the G1/S phase and G2/M phase checkpoints. The mechanism for this activity at the G1/S phase checkpoint is well understood, but its mechanism of action at the G2/M phase checkpoint remains to be elucidated. The p53 protein is thought to prevent chromosomal replication specifically during the cell cycle if DNA damage is present. In addition, p53 can induce a type of programmed cell death, or apoptosis, under certain circumstances. The general goal of p53 appears to be the prevention of cell propagation if mutations are present. The p53 protein acts as a transcription factor by binding to certain specific genes and regulating their expression. One of these, WAF1 or Cip1, is activated by p53 and is an essential downstream mediator of p53-dependent G1/S phase checkpoint control. The function of p53 can be suppressed by another gene, MDM2, which is overexpressed in certain tumorigenic mouse cells and binds to p53 protein, thus inhibiting its transcriptional activation function. Other cellular proteins have been found to bind to p53, but the significance of the associations is not completely understood in all cases. The large number of human cancers in which the p53 gene is altered makes this gene a good candidate for cancer screening approaches.
When a stream's velocity decreases from 300 to 200 centimeters per second, which size sediment will be deposited?
Middle size sediment will be deposited on the ground when the speed of flowing water decreases.
Deposition of sedimentsWhen a stream's velocity decreases from 300 to 200 centimeters per second, the middle size sediment will be deposited because of the lowering velocity of the stream. Big size sediments hardly move by the water of the stream.
While on the other hand, middle and small sized sediments easily moved by the flowing water due to their light weight so we can conclude that middle size sediment will be deposited on the ground when the speed of flowing water decreases.

Multigene families include two or more nearly identical genes with related functions. A classical example is the set of genes for globin molecules, including genes on human chromosomes 11 and 16. Some of these genes produce hemoglobin only in the fetus or embryo. Others are very similar to functional genes, but have accumulated mutations and are no longer functional. A scheme of alpha globin gene family and beta globin gene family. The alpha globin gene cluster is located on chromosome 16 and includes the loci zeta, pseudozeta, pseudoalpha-2, pseudoalpha-1, alpha-2, alpha-1, pseudotheta. The zeta gene produces hemoglobin in the embryo; alpha-2 and alpha-1 produce hemoglobin in the fetus and adult. The beta-globin locus is located on chromosome 11. The order of the genes in the beta-globin cluster is epsilon, gamma-G, gamma-A, pseudobeta, delta, beta. Epsilon produces hemoglobin in the embryo, and gamma-G and gamma-A produce hemoglobin in the fetus. Delta and beta produce hemoglobin in the adult. What is the most likely mechanism for a gene sequence moving from one chromosome to another
Answer:
Transposition to different chromosomes by the ancestral gene
Explanation:
Transposable Elements (TEs), also known as jumping genes, are genetic mobile elements which are able to move from one location to another on the genome. There are two major mechanisms of TE transposition: 1-cut-and-paste mechanism, where one particular TE is inserted into a new position on the genome without replication, and 2-copy-and-paste mechanism, where a new copy is generated and the original TE remains at the original genomic site. In this case, it is likely that new TE copies containing the ancestral (duplicated) gene have proliferated through the copy-and-paste mechanism.

Answer:
Honestly it depends...
Explanation:
I would say overall fungi are beneficial because they feed on dead organic matter. They recycle most of the carbon and release nutrients to be used by other organisms. They are also used for medicinal purposes. Not to mention yeast is a fungus and bread is yummy.
But certain fungi are deadly if ingested or linked to plant and human diseases. Also mold is a fungus and nobody likes mold.
Explain the scientific evidence that supports continental drift.
Answer:
- The geography of the continents (they fit each other, contain similar mountain ranges, etc)
- The distribution of fossils and rocks
- The locations of ancient climatic regions
Explanation:
The continental drift theory states that continents moved across geologic time, plowing through oceans and drifting to different parts of the planet. The continental drift theory is associated with Alfred Wegener, who the first in using this terminology in 1912. Some of the most important lines of evidence that support the continental drift theory are the movement of continents on tectonic plates, the presence of evolutionarily related plant and animal fossils in different continents, paleoclimate indicators (e.g., glacial striations), etc.
