The burning of fossil fuels and other human activities are contributing to
increasing carbon dioxide levels in the ocean. In one ocean ecosystem,
the change in carbon dioxide levels is causing an increase in the algae
population and a decrease in the phytoplankton population. Algae and
phytoplankton both produce energy through the process of
photosynthesis. Which of the following describes how human activity will
likely affect this ocean ecosystem?*
o

Why is the making of sedimentary rock a physical change?
Answer:
Igneous rocks go through the physical change of erosion, where the rock is broken apart by wind and rain. The resulting sediments are deposited on the ground or ocean floor and start to be compressed into sedimentary rock.

What covers the skeletonANSWER-
periosteumExplanation:
The tough, thin outer membrane covering the bones is called the periosteum. Beneath the hard outer shell of the periosteum are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone. Muscles, ligaments, and tendons may attach to the periosteum.[tex] \rm\color{wheat}by - \: denfor[/tex]

Why is the making of metamorphic rock a chemical change?
Answer:
Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
Of the following disturbances, which can only be categorized as extreme (i.e., could not be considered small or medium
in scale)? (1 point)
O hurricane flooding in several cities in Texas
O wildfire across several counties in California
O volcanic eruption in the middle of the ocean
O rapid glacial retreat due to climate change
Rapid glacial retreat due to climate change.
The disturbances, which can only be categorized as extreme, are the rapid glacial retreat due to climate change.
What is the glacial retreat?The glacial retreat is when the terminal does not extend as far.
When the ice melts quicker than the snow falls, the retreat of glacial occurs.
When the glacier loses its ice more it gains, than water level rises.
Sometimes, the pieces of ice rocks float in between the water.
Thus, the correct option is D.

Please help! After 1973, American scientists began to make serious efforts to develop technologies that create
electricity from renewable resources. Do you think this step was necessary? Explain your answer.
Answer:
Yes
Explanation:
Yes, because the embargo of 1973 showed how dependent we are on just one type of fuel, so it was necessary to start looking at different ways to create energy.

3. How can mutations benefit a species?
Answer: They can lead to speciation.
Explanation: Speciation can introduce new survival traits to a species which can lead to higher survival rate in their environment and that can lead to population growth.
Answer:
They result in specific gene variants that aid organisms in adapting to environmental changes. Beneficial mutations are required for evolution to take place. They improve an organism's chances of survival or reproduction, and as a result, they are likely to become more frequent over time.

In arthropods, What are the tubes that enhance respiration called?
Answer:
tracheae
Explanation: mark me brainliest!!
Most insects have a respiratory system akin to ventilation in a building. Tubes called tracheae run throughout their bodies delivering oxygen.
During winter, Alaska typically sees a decrease in the number of prey animals. In
order to survive, Arctic Foxes will eat berries, seaweed, insects, and larvae. If it is so
cold one winter that even these foods are depleted, Alaska's population of Arctic
Foxes is likely to -
Answer:
Decrease
Explanation:
If the foxes have nothing to eat, some will starve and die so the population will decrease.

how mutation cause colorectal cancer
Answer:
A very small portion of colorectal cancers are caused by inherited gene mutations. Many of these DNA changes and their effects on the growth of cells are now known. For example: Familial adenomatous polyposis (FAP), attenuated FAP (AFAP), and Gardner syndrome are caused by inherited changes in the APC gene.Why should a scientist use a plasmid with a GFP gene when inserting a new gene?
A) The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene
insertion worked.
B) The GFP gene will remove other genes, making it easier to see the effects of the new
gene.
C) The GFP gene is not well understood, so inserting it would be a valuable experiment all
on its own.
D) The GFP gene will stop the gene insertion from falling apart, making the results more
reliable.
Answer:
the answer is a
Explanation:
the GFP gene will make cells glow green in ultraviolet lights, confirming that the gene intersection worked.
A scientist use a plasmid with a GFP gene when inserting a new gene because it makes the phenotypes that is easily detectable. The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene insertion worked.
What is a GFP plasmid ?GFP plasmid is an engineered plasmid to be used in the biotechnology where the use of GFP will be in order to make up the genetic modified organisms.
The GFP plasmid will make up the multiple number of reporter genes that will help to detect the mutations and the inserted gene . The most notice GFP gene that will be detected is GFP that is green fluorescent protein and the ampicillin resistant gene that will make the gene look different from other types of genes present.
The GFP gene will make cells glow green in ultraviolet lights, confirming that the gene insertion worked. This can be detected by the gel running when the screen is seen.
