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.

Answer:
Pluto is big enough to be considered a dwarf planet, but it has not been classified as such in some peoples views such as Quaoar and Sedna.
Explanation:
The both reach the otter layers of the solar system just like Pluto and are as I said above big but not big enough to be considered a dwarf planet
The ribosome slides one codon down the mRNA. <u> Option B.</u>
Transcription is the technique of the producing of RNA from DNA. Translation is the gadget of the formation of protein from RNA. Translocation is the motion of substances in vegetation from the leaves to other elements of the plant. Translation takes area at the ribosome, which includes rRNA and proteins. In translation, the instructions in mRNA are take a look at, and tRNA brings the perfect collection of amino acids to the ribosome.
Metabolic techniques, particularly the products of photosynthesis are transported from the leaves in which they may be formed to unique factors of the plant. This shipping of soluble photosynthetic products is known as translocation and takes vicinity in a part of the vascular tissue called the phloem. A mutation wherein non-homologous chromosomes change stretches of DNA. Autosomal issues. Autosomal troubles affect each women and men.

Answer: Where would the blood come from if there were a blockage just posterior to the middle cerebral artery on the left? If blood could not get to the middle cerebral artery through the posterior circulation, the blood would flow around the circle of Willis to reach that artery from an anterior vessel.
