Answer:
Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another.
Explanation:
When Arizona's Grand Canyon formed, squirrels and other small mammals that had once been part of a single population could no longer contact and reproduce with each other across this new geographic barrier. They could no longer interbreed. The squirrel population underwent allopatric speciation.

Can someone define tropism and describe the different types of tropism exhibited in plants?
Answer:
Hello.
Tropism is specific to the direction of the stimulus. Plants can either display a negative or positive movement in response to a stimulus. It is positive tropism when the movement is towards the direction of stimuli while it is negative tropism when the movement is away from the stimuli.
Tropism is a response to certain stimuli. A positive tropism is moving towards the stimuli, while a negative tropism is moving away from a stimuli.
Positive Phototropism - Growing towards light
Negative Phototropism - Growing away from light
Positive Thigmotropism- Moving towards touch
Negative Thigmotropism- Moving away from touch
Positive Hydrotropism - Growing towards water
Negative Hydrotropism - Growing away from water
Positive Gravitropism - Growing towards ground
Negative Gravitropism - Growing upwards

What interactions occur between two hexane molecules?.
Hexane do not have any dipole-dipole interactions because they are non-polar molecules. Dispersion forces will occur between two hexane molecules.
What are Intermolecular forces?The forces of attraction present between atoms, molecules and ions when they are present close to each other , this type of force is known as Intermolecular Forces. An intermolecular force is experienced between two particles when a positively (+) and negatively (-) charged particles are attract to each other.
These forces are weak in nature when these molecules do not possess strong forces of attraction between them resulting in a repulsive form.
There exist four types of intermolecular forces which are as follows:
1. Ionic bonds
2. Hydrogen bonding
3.Van der Waals dipole-dipole interactions
4. Van der Waals dispersion forces
Among all the above mentioned forces, Ionic Bonds are the strongest Intermolecular force.
Thus, hexane do not have any dipole-dipole interactions because they are non-polar molecules. Dispersion forces will occur between two hexane molecules.

Why is it important to aquatic life (in ponds and lakes) that water freezes top down?
Answer:
If ice were to form from the bottom of a lake or pond upwards, all life in that water would eventually freeze and die. Freezing of water from the top down is critical for aquatic life to survive in brutally cold winters, since surface ice actually helps insulate and slow the cooling of the water below.
What type of data is non numerical
Answer:
qualitative
Explanation:
There are 2 main types of data - qualitative and quantitative.

Binary fission can sometimes be advantageous in evolutionary processes, allowing new daughter cells to adapt to different environments.
Which of the following MOST LIKELY leads to a possible advantageous change during binary fission?
Possible answers:
A= DNA Replication
B= Crossing over
C= A mutation
D= Meiosis
Answer:
C
Explanation:
DNA replication should copy the DNA exactly, so should not produce any changes to the DNA sequence.
Crossing over does not occur in prokaryotes, it only occurs in eukaryotes. The same is true for meiosis, it does not occur in prokaryotes as it is a specialized type of cell division that creates gametes in multicellular organisms
Mutations create changes to the DNA sequence. By chance, occasionally these changes can be beneficial and give the new cell an evolutionary advantage. For example resistance to antibiotics, or an ability to digest a new nutrient.

The size of a tsunami depends on the energy involved during its formation. which of these events is not likely to cause a tsunami?
a.
an earthquake beneath the ocean floor
b.
a massive underwater landslide
c.
the rise and fall of ocean tides
d.
an avalanche caused by melting ice caps
Answer:
C-the rise and fall of ocean tides on edmentum
Explanation:
Tidal waves do not produce tsunamis, and they are significantly less predictable than tide-related waves. Therefore, option (C) is correct.
What is Tsunami?A tsunami is a succession of waves in a body of water brought on by the shifting of a significant amount of water, typically in an ocean or a sizable lake. A tsunami can be produced by earthquakes, volcanic eruptions, and other undersea explosions that occur above or below the surface of the water.
Other possible effects include the devastation of homes and businesses, ports and harbors, cultural resources, utilities, and crucial infrastructure and facilities, in addition to the loss of life and widespread injury. Access to essential utilities including water, sewer, and power may be lost.
Therefore , option (C) the rise and fall of ocean tides do not result into tsunami.

A it is a natural resource.
B it can be replaced in a short amount of time.
C the resource forms very quickly.
D the resource forms very slowly.
The statement (B) is correct. Biosphere can be replaced in a short amount of time.
What is biosphere?The biosphere, also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere is virtually a closed system with regard to matter, with minimal inputs and outputs.
Moreover, the biosphere is the region of the earth that encompasses all living organisms: plants, animals and bacteria. It is a feature that distinguishes the earth from the other planets in the solar system.
Therefore, the portions or regions where organisms are found are collectively called the biosphere. Thus, it can also be said that the biosphere is the sum of all the ecosystems on Earth.

Occasionally, chromosomes fail to separate during meiosis, leading to aneuploidy. It is an aberration in the number of chromosomes.
What is aneuploidy?Aneuploidy can be defined as an aberration in the number of chromosomes in a given cell.
Aneuploidy occurs when chromosomes are not correctly separated during cell division (either mitosis or meiosis).
A common aneuploidy is a trisomy, where a diploid cell has three homo-logous chromosomes instead of two.
