Information about the parts of a cell, its location and
role will help describe the appearance of a cell's content.
Organelles are cell structures that include the nucleus, cytoplasm,
cell membrane among others. One can view these using a light microscope.
1. Cell Membrane is a fluid mosaic. It is the outer boundary
of the cell.
2.Cytoplasm is the fluid inside the cell. It is located
between the nucleus and the cell membrane.
3.Nucleus is the control center of the cell and is located
at the center.
<span>Eukaryotic organisms that handle the decomposition of dead organisms as well as absorbing dissolved nutrients from their surrounding environment are found in the fungi kingdom. Some of the organisms included in the fungi kingdom are mushrooms, molds, puffballs, truffles, and yeasts. In all, there are over 70,000 different types of fungi.</span>
Answer:
they likely evolved from the same ancestor
Explanation:
because they have similar features
The quantity of water in the water table can change rapidly depending on the rate of extraction. As the level of water decreases in the aquifer, there is less available water to be pumped. If the rate of potential groundwater recharge is less than the rate of extraction, the water table will be too low for access.
Answer:
Clues that can be used to determine whether the movement of solutes through the membrane is passive or active could be the molecule size, membrane potential, and the presence/absence of membrane protein.
Explanation:
Solutes transport through the cellular membrane depends on the solute size, membrane potential, and the presence/absence of integral membrane protein.
There are two types of transport: Active and passive.
- Passive transport: It does <u>not need energy</u>; it is driven by a chemical potential gradient. <u>Small molecules</u> with no charge are transported through the membrane in a gradient favor, from a high concentration region to a low concentration region. There are two types of passive transport: <em>By simple diffusion</em> (small molecules pass through the membrane by themselves) and by <em>facilitated diffusion</em> (molecules are helped by integral membrane proteins to pass through the membrane). In facilitated diffusion, the helping protein can be a <u>channel protein</u> (hydrophilic pores that allow the molecule to pass with no interaction) or a <u>carrier protein</u> (proteins with mobile parts that suffer modification as the molecule pass to the other side).
- Active transport: It <u>does need ATP energy</u> to pass the molecule through the membrane, as they have to <u>move against the electrochemical gradient</u>. This kind of transport is always mediated by a <u>carrier protein</u>. These proteins join with the molecules and suffer changes as they pass the solute to the other side of the membrane. An important example of this kind of transport is the sodium-potassium bomb.
