What is the function of the cell wall in the onion cell you looked at?

Biology

Brilliant_brown [7]3 years ago

The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onionfruiting body (bulb) is used for storing energy, not photosynthesis. Each plantcell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole.

tree and nest
If a robin builds a nest in a big tree, the robin benefits and the tree is not helped or harmed. This type of symbiotic relationship is called commensalism, and it is between the tree and the nest/Robin.

<span>There are several types of biotic relationships that is occurring every single moment in the ecosystem and commensalism is one. In contrast, parasitism is the biotic relationship where one organism doesn't benefit from the other and is harmed. In this scenario with human beings and mosquitos, this phenomenon of interaction is distinguished as parasitism where mosquitos draws blood that contains nutrients from the human tissue to use it as its source of food and then leaves harmful substances and bacteria in the human’s blood stream.<span> </span></span>

The major difference between angiosperms and gymnosperms comes from the _____.
kumpel [21]

Answer:

presence or absence of a protective covering over the ovule

Explanation:

In angiosperms, seeds develop from ovules and are enclosed in the ovary. So, their is the presence of protective covering making the seeds enclosed.

On the other hand, gymnosperms have seeds that are borne on cones, so they are naked due to the absence of any protective covering over the ovule.

What is a possible effect of an error during transcription?
Leviafan [203]

A possible effect of an error during transcription is the wrong amino acid chain, will be produced.

Option D

<h3><u>Explanation: </u></h3>

The "wrong amino acid chain", will be produced as a possible effect of an error during transcription. A mutated set of proteins will start getting produced. They will have different or faulty functioning. In some cases, they won't have any functions of their own.

To avoid the possibility of an error, the transcript goes through a process of proofreading which further eliminates the chances of a wrong protein being developed.

Local and global winds are set in motion by air moving in convection cells. Describe the motion of air in a convection cell. Be
IrinaVladis [17]

Answer:

Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.

The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense  and begins to rise. The cooler and denser air mass from the poles rushes in, through the  lower atmosphere, to replace the void of the rising air.

When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.

The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.
