Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
Answer:
As it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock because most such magmas are hotter than the melting temperature of crustal rock.

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
silent
missense
nonsense
deletion
Answer:
Deletion
Explanation:
I think it is the last one
Deletion
If it really helped please give me brainliest
A nonsense mutation is one mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.
Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene.
The CFTR gene codes for the CFTR protein whose function is as an anion channel (chloride ion) which helps control the movement of water in and out of the membrane of cells that are specialized to produce mucus, sweat, saliva, tears and digestive enzymes
When CFTR protein is defective or absent, thick, sticky mucus accumulates in these cells, obstructing the airways and glands.
The most common mutation of the CFTR gene is a deletion whereby the codon for the amino avid phenylalanine is deleted resulting in the production of a defective CFTR protein.
Another form of mutation in the CFTR gene is a nonsense mutation in which a stop codon is inserted in the middle of the gene resulting in the production of a shortened CFTR protein, which is then degraded by the cell.
Therefore, a nonsense mutation in the CFTR gene leads to cystic fibrosis by causing translation to end earlier in the gene sequence.

Warm air always wants to _________________.
a. rise (will give brainiest)
B. fall
c. move left
d. move right
Answer: A(Rise)
Explanation: Air flows from high pressure, to low pressure. for example: there are 2 rooms, one is cold and is warm that of warm room is thinner air rising towards the ceiling when the air from the two rooms gets mixed. now the cold air will be leaving the room close to the floor. At the same time, warm air from the warm room will rise and move into the cold room close to the ceiling

When a cell gains water, what will happen to its size and mass?
Answer:
The cell will swell up and eventually burst.
Explanation:
Cells swell if there’s more salt in a cell than outside it, the water will move through the cell membrane into the cell, causing it to increase in size. if too much water gets in, the cell will burst.

Old rivers-Have many meandersYoung rivers-Carry large objectsMature rivers-Carry medium-sized objectsWhat are rivers?Rivers are bodies of flowing water that are typically found on the surface of the Earth. They are formed by the accumulation of precipitation, such as rain or snow, in a specific area and flow in a defined channel towards an ocean, a lake, or another river. Rivers can vary greatly in size and length, with some being just a few meters wide and a few kilometers long, while others can be several kilometers wide and thousands of kilometers long.
They are an important resource for humans and other living organisms, providing water for irrigation, drinking, and industrial uses, as well as serving as habitats for a wide variety of plant and animal life. Rivers also shape the land they flow through, eroding and depositing sediment, and creating features such as valleys, deltas and canyons.
