Where does the cell spend most of its time?
Answer:
interphase
Explanation:
interphase
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Scientists have found two leaf fossils that come from very different climates. The smooth-edged leaf is from a warm climate, and the toothed-edged leaf is from a forest in a cooler climate. If the toothed-edged fossil was found in the desert, what hypothesis could you draw from this information.
The climate changed from cool forest to hot desert.
THe area was once covered by ice.
There was once snow in this desert.
The area was once under water.
Answer:
The first one has to be the answer
Explanation:
If the area had once been covered by ice or snow, then there would be no place to get the warm leaf from.
If the area was once underwater then I don't know how it would have grown a cold forest, a tropical forest, and then a desert.
It'd make more sense if you started with a cold forest with sharp leaves, that slowly became a warmer forest with smooth leaves, only so it could become a dessert with only leaf fossil remains.
so ya the first one is your answer.
The climate changed from cool forest to hot desert is the hypothesis which can be concluded.
What is Hypothesis?This can be defined as a proposed explanation for a particular phenomenon through various sources.
We were told that the toothed-edged leaf is from a forest in a cooler climate but was found in the desert which therefore means that the climate changed from cool forest to hot desert.

Anthony returns home from work. When he opens the front door of his house, he detects a strong smell of gas. He suspects that his gas pipe is leaking. Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of
Given what we know, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.
What is sensation?The sensation is a process that activates for each of the 5 senses. In this process, sensory neurons receive a stimulus and activate, sending a neural impulse to the brain with the information gathered. This information resulted in the ability to identify the smell as gas.
Therefore, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.

WILL GIVE BRAINLIEST / Dora was asked to label the upwelling and downwelling locations on this map of the earth. Dora labeled A as an area of downwelling. Which one of the following reasons does NOT support her answer?
1 A is near the south pole and downwellings are usually near the poles.
2 The cold, salty water forming at point A has a higher density than the warm water and will need to sink.
3 A has warm surface water coming in and a cold water current going out.
4 A is near the equator and downwellings are usually near the equator.
Answer:
I think it's 3 not sure tho because it can also be 4
Answer:
4
Explanation:
Downwelling usually occurs near the poles, and point A is near the equator, so it would be a likely spot for upwelling to occur

Which scenario is an example of the transfer of thermal energy by conduction? A. Hot air circulates in an oven. . B. Hot water heats up the cup that it is in. C. The air in a hot-air balloon is heated by a gas burner. D. You warm your feet in front of a fireplace.
Answer:
c.the air in a hot air balloon is heated by a gas burner.
The air in a hot-air balloon is heated by a gas burner - this is an example of the transfer of thermal energy by conduction.
What is thermal conduction?Thermal Energy is energy resulting from the motion of particles.
The process by which heat is transferred from the hotter end to the colder end of object is known as conduction. Thermal conduction is the diffusion of thermal energy (heat) within one material or between materials in contact.
In gases, conduction is due to the collisions and diffusion of molecules during their random motion. Photons in this context do not collide with one another, and so heat transport by electromagnetic radiation is conceptually distinct from heat conduction by microscopic diffusion and collisions of material particles and phonons. But the distinction is often not easily observed unless the material is semi-transparent.
The correct answer is option C.
