A scientist is observing a onion cell and a human cheek cell under a microscope which observation does she MOST LIKLEY make A) The onion cell have lysosomes, and the cheek cell does not B) The cheek cells have larger vacuoles than the onion cells C) The cheek cells have a nucleus, and the onion cell does not D) The onion cells have a cell wall, and the cheek cells do not
Final answer:
The primary observation a scientist would make is that onion cells, which are plant cells, have a cell wall for structural support, unlike the cheek cells of humans that lack a cell wall.
Explanation:
A scientist observing an onion cell and a human cheek cell under a microscope will most likely make the observation that the onion cells have a cell wall, and the cheek cells do not. This is because onion cells, being plant cells, have a rigid cell wall surrounding their cell membrane which provides structural support and protection. In contrast, human cheek cells, like all animal cells, lack a cell wall and instead only have a cell membrane which is flexible and allows for a variety of shapes.

Explanation:
A student set up an experiment to show the effect of light color on photosynthesis in Elodea plants. She filled three test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic so the phenol red turned yellow. She exposed Tube A to white light, Tube B to green light, and Tube C was wrapped in aluminum foil. Which of the tubes should she expect to turn red the fastest?
Answer:
Tube A will turn red the fastest.
Explanation:
Tube A will turn red fastest because Elodea plants will take up the white light and carry out photosynthesis.In tube B, the red colour will not be generated fastly because plants do not use green light. Usually, the green light is just reflected by the plants and it is not absorbed.
In tube C, no photosynthesis will be able to occur because due to the wrapped aluminium foil the plants could not receive any light for photosynthesis.
From the setup of the experiment to show the effect of light color on photosynthesis in Elodea plants, the solution in Tube A should turn red the fastest.
White light is essentially a mixture of all light colors. Hence, the Elodea plant in Tube A will absorb the most effective light color from the white light for its photosynthesis, utilizing the carbon dioxide in the tube's solution faster and making it turn red.
Green light is generally considered to be the least efficient of all light colors when it comes to photosynthesis. Hence, the rate of consumption of carbon dioxide from the tube with green (Tube B) light would be slow.
There will not be any photosynthesis in Tube C because there is no light for the process. the aluminum foil would have blocked any form of light that could get to the plant in the tube.

What type of succession shown from figure a to figure b
PLeASe ASAP !!!!
Answer:
The correct answer is secondary succession.
Explanation:
A slow process by which ecosystems develop and modify with time is termed as ecological succession. An array of community modifications that occurs on a previously colonized, however, damaged or disrupted habitat is termed as the secondary succession. Secondary succession takes place in the regions which were cleared of the prevailing vegetation or due to the catastrophic incidents like fire.
The phenomenon of secondary succession generally takes place at a rapid rate in comparison to the primary succession. This takes place because of various reasons like the undisturbed root systems present in the soil that helps the plants to regenerate at a quick rate, a prevailing seed bank of suitable plants in the soil, and the structure and fertility of the soil that would have been modified significantly by the species that were present in the previous colony, making the soil more appropriate for growth and development.
Why does secondary succession occur faster than primary succession?
Answer:
Soil with nutrients is already present. Seeds are present from earlier occupants, brought in by wind, and/or germinate after fire.
Explanation:
Sample answer hope this helps!!! Brainliest?
Secondary succession usually occurs faster than primary succession because the components are already present. whereas in primary succession, there is no soil and it needs to form.
as pioneer species must inhabit the area, they must die, and as this happens repeatedly, soil formations take place.
What is Ecological Succession?Ecological succession is the process by which the mix of species and habitats in an area varies over time. Gradually, these communities replace one another.
Thus, Secondary succession usually occurs faster than primary succession.

The current eccentricity of Earth is .017. The shape of the Earth's orbit changes from being elliptical (high eccentricity) to being nearly
circular (low eccentricity) in a cycle that takes between 90,000 and 100,000 years. When the orbit is highly elliptical, the amount of
insolation received at perihelion would be on the order of 20 to 30 percent greater than at aphelion. What would be the predicted
result of this change?
The awnser is “A much warmer climate than what we are currently experiencing”
Answer:
In the given case, a much warmer climate will be experienced in comparison to what one is experiencing at the present time.
Explanation:
When the orbit of the Earth changes its path, one can witness a variation in the Earth's climatic conditions. Like when the Earth comes nearer to the Sun, the climate of the Earth becomes warmer. However, when the axis of the Earth shifts slightly away from the Sun, one can witness a reduction in the Earth's temperature.
Therefore, in the given case, the isolation received at perihelion would be twenty to thirty percent more in comparison to aphelion when the orbit is more elliptical, this condition eventually results in a warmer climate.

The structure labeled “A” in this diagram of a virus is called the
a. RNA envelope
b. Capsid
c. Nuclear membrane
d. Viral genome
The structure labeled “A” in this diagram of a virus is called the b. Capsid. Therefore, b. Capsid is correct .
The capsid, a crucial component of viruses, serves as a protective protein shell enveloping the viral genome.
Comprising subunits known as capsomeres, the capsid exhibits diverse structural forms, such as icosahedral, helical, and enveloped.
The icosahedral shape, with 20 triangular faces, is a common configuration, offering stability and efficiency in encapsulating the genetic material.
Capsomeres possess the unique ability to self-assemble, forming the capsid that shields the viral genome from external threats and damage.
Additionally, the capsid plays a pivotal role in facilitating the virus's attachment to host cells, a crucial step in the infection process.
Some viruses boast an additional layer beyond the capsid, known as the RNA envelope.
This outermost layer, though not labeled in the diagram, comprises a lipid bilayer studded with proteins.
The envelope serves several functions, including aiding the virus in evading the host's immune system and facilitating the virus's entry into host cells.
This membrane-like structure enhances the virus's adaptability and interaction with the host environment.
It's essential to note that the nuclear membrane mentioned is distinct from the viral components.
The nuclear membrane surrounds the nucleus in eukaryotic cells, providing a boundary between the nucleus and the cytoplasm.
The viral genome, on the other hand, represents the genetic material of the virus, not a membrane.
These structural elements is fundamental to deciphering the intricacies of viral infection and host interactions in various biological contexts.
