What would happen if the concentrations of carbon dioxide and methane rose too high?
Answer:
I'm assuming this means concentrations of the atmosphere*
Explanation:
Carbon dioxide are both considered greenhouse gasses. This means whenever they are in the atmosphere, they absorb heat from the sun and trap it within the atmosphere. In general, greenhouse gasses are a good thing. They trap heat in the Earth during nighttime so we do not freeze when we don't have the sun. However, since the Industrial revolution, the overuse of fossil fuels which are made of carbon and sometimes have high methane concentrations have lead to an excess amount of these gasses in our atmosphere. If concentrations become too high, the Earth's climate will continue to display higher average temperatures, leading to a complete change in our environments as once glacial areas will begin to display more temperate climates, and temperate and warm climates will become even hotter. Ecosystems in every area will be severely damaged, with many species likely facing extinction. Additionally, sea levels will rise much higher, both due to the melting of glaciers into the ocean and also because warmer climates will make the ocean warmer, meaning the molecules of water will spread farther apart and increase the volume of the ocean.

How can cells from the same organism have such different shapes and functions?
Answer:
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity. B Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
Explanation:
Answer:
Because cells are not only characterized by by their genetic material and other interior components, but also by the genes they express. Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. For example melanocytes in the skin are highly specialized cells which mostly make the pigment melanin. Plasma cells on the other are highly specialised for making antibodies.
7 Infer Before scientists were able an to view and study the ocean floor directly , why might they have expected the ocean floor to be smooth and flat ?
Answer:
Rocks deteriorating the ocean floor
Explanation:
As rocks scrape past the ocean floor they chip away at it smoothing it (erosion) out but due to continental drift and magma rising and cooling it causes the new igneous rock forms on the ocean floor making it rough and rugged.
When thinking about this think about a pebble on the beach, what it is?
rounded due to erosion just as scientists thought the ocean floor would be.
8. Describe: Locate the Sun on the H-R diagram. How will the Sun's luminosity and
temperature change as it ages? How will these changes affect its position on the diagram?
Answer:
It will eventually become less bright and cooler.
Explanation:
Astronomers estimate that the Sun's luminosity will increase by about 6% every billion years. This increase might seem slight, but it will render Earth inhospitable to life in about 1.1 billion years. The planet will be too hot to support life.
The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this.
Answer:
it will turn into a super giant then eventually turn into a white dwarf star

Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers. So, the correct option is B.
What are sedimentary rock layers?The formation of sedimentary rocks involves the accumulation or deposit of mineral and organic particles at the Earth's surface, following by cementation. The mechanisms that lead to the accumulation of these particles are collectively referred to as sedimentation.
Sediment refers to the little particles that make up sedimentary rocks and can be either geological detritus (nitrogen and phosphorus) or biological detritus (organic matter). Sandstone, limestone, and mud are examples of typical sedimentary rocks.
These rocks frequently begin as sediments that are transported by rivers, then are dumped in lakes and oceans. The sediments become dry and cement together to form rock when they are buried. Volcanic ash can be found in tuffaceous sandstones. Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers.

2. in cardiac muscle, acetylcholine binds to muscarinic acetylcholine receptors (machrs), which are g-protein coupled receptors, which elicit a signal transduction pathway that induces cardiac muscle to relax. outline how g-protein coupled receptors induce signal transduction pathways including relevant secondary messengers.
3. interpret dr. peterson’s statement that active transport is essential for facilitated diffusion of na+ ions to occur in muscle cells. how are na+/k+ pumps involved in this process? sketch a na+/k+ pump indicating conformational changes and energy usage steps and identify ions that are moved during the cyclic process.
4. generally, after neurotransmitters are released in the neuromuscular junction, many of the neurotransmitters or some of their components are recycled by a reuptake mechanism inherent in the pre-synaptic neuron. considering that the reuptake mechanism is often a sodium-dependent process that utilizes membrane potential, what type of membrane transport might you expect to be in play here?
Uniporter allows the movement of a subtance in one direction, symporter two molecules in the same sense and antiporter two in opposite sense. Nicotinic acetylcholine receptors are linked to symporters to allow the movement of neurotransmitters. G protein function is coupled to second messengers such as cyclic AMP, active transport allows the movement of substance again a concentration gradient and reuptake mechanism involves symporter transport.
What are uniporter, symporter, and antiporter?The terms uniporter, symporter, and antiporter make reference to different types of channel proteins located in the cell membrane which allows the movement of molecules through this selectively permeable barrier.
Moreover, nicotinic acetylcholine receptors are receptors that bind to certain neurotransmitter chemical messengers such as acetylcholine in order to allow the movement of ions through the membrane.
Therefore, with this data, we can see that uniporter, symporter, and antiporter are different classes of channel proteins in regard to the movement of molecules in and out of a selectively permeable barrier (i.e. the cell membrane).
