Listen How are channel and carrier proteins similar? Select all that apply.
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
B. Channel and carrier proteins are both types of facilitated transport.
C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.
D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.
Answer:

Explanation:
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
Channel and carrier proteins are both types of facilitated transport.
Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.
Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.
So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.
This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.
Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions. When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.Consequently, when an ion channel opens, the potential difference between the two compartments is altered.
Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.
This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:
Uniport, a single molecule translocates in only one direction.Simporte, two molecules that translocate in the same direction.Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

Bart believes that mice exposed to microwaves will become extra strong (maybe he's
been reading too much Radioactive Man). He decides to perform this experiment by
placing 10 mice next to a microwave for 10 seconds. He compared these 10 mice to
another 10 mice that had not been exposed. His test consisted of a heavy block of wood
that blocked the mouse food. He found that 8 out of 10 microwaved mice were able to
push the block away. 7 out of 10 of the non-microwaved mice were able to do the same.
What was one of the constants in this experiment?

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

What is biology of brown rat?
Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?
A.Spiders do not have eight legs.
B.Insects do not have six legs.
C.If spiders evolved first, six legs is the derived trait.
D.Spiders do not have derived traits, since they evolved first.
Answer: The answer is C
Explanation:
The piece of information that Antonio is considering is that if spiders evolved first, six legs are the derived trait. So the correct option is C.
What are derived traits?A trait that has been observed in a group of organisms but was not observed or was absent in the previous common ancestor of the group.
These are also the traits that are not present in the group of organisms under consideration but were observed in the previous common ancestors. This is called the secondary loss of traits.
Therefore, derived traits are not only concerned with the development of new traits but also the loss of old traits. Simplicity in a structure or function is a secondary derived trait.
Thus, because the spiders evolved before other insects, the presence of 6 legs in insects is a secondary derived trait as it represents simplicity in structure. Spiders are not derived because they are the common ancestors of the group of insects.
Therefore the correct option is C.

What happened if we add normal saline instead of PBS during beta amylase extraction?
Answer:
hi
Explanation:
Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.
How saline water affects beta amylase extraction?PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.
When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.
As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.
Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.
