We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.
The characteristic features of active transport are:
-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.
-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.
-The process of active transport can be inhibited by inhibitors that react with the protein side chains.
-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.
The various types of processes that depend on active transport are:
-Absorption of amino acids from the gut.
-Absorption of mineral ions by plant roots.
-Excretion of urea and hydrogen ions by the mammalian kidney.
-Exchange of sodium and potassium ions in nerve cells.
-Filling of the contractile vacuole in amoeba.
The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.
Additional information :- Some intrinsic protein molecules function as molecular pumps. These permit the cell to go for active transport to accumulate glucose or ions against the concentration gradient. Cells that undergo active transport have abundant mitochondria that provide ATP needed to power active transport.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Where is the rainshadow area on the Big Island of Hawaii? Please help
Answer:
Applied to the Big Island, since the trade winds blow from the northeast and must pass over the mass of Mauna Kea and Mauna Loa, it means that the Hilo side is considerably rainier than the Kona side. The best place to view this rain shadow effect is to drive from Kohala to Hilo through the town of Waimea.

What happens to the cell's
genetic information during the cell cycle?
Answer:
Mitosis results in two nuclei that are identical to the original nucleus. So, the two new cells formed after cell division have the same genetic material. During mitosis, chromosomes condense from chromatin. ... At the end of mitosis, the cell has two identical sets of chromosomes in two separate nuclei.
Explanation:

Why can cells in the bone marrow produce both red and white cells
Answer:
1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.
Explanation:
2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.
3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

3. A strain of cells undergoes a mutation that increases the permeability of the inner
mitochondrial membrane to hydrogen ions.
a) What effect would you expect this mutation to have on the process of cellular
respiration? 12
b) Assuming the mutant cells can survive, how might the metabolic requirements of
these cells differ from those of a non-mutant strain of the same variety? 12
A mutation that involves the permeability of the inner mitochondrial membrane to protons (H+) will affect the amount of ATP. If mutant cells can survive, then they will need more energy to create a suitable gradient.
Cellular respiration is a series of metabolic reactions by which aerobic cells can generate energy in the form of ATP by using the chemical energy stored in the foods.
Cellular respiration can be divided into three sequential stages: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is then used to generate ATP by means of a protein complex known as ATP synthase.

Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries

Explanation:
1.) Using the information in the table below, determine the amino acid sequence or get is coded for by the mRNA sequence: AUG-UCU-GAU-UGG-UAC.
2.) What is the start codon? What are the 3 stop codons?
The amino acid sequence here is Met-Ser-Asp-Trp. The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.
The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.
The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).
The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.

Match the digestive organ on the left with its function.
Answer:
pancreas: secretes digestive enzymes into the small intestine
esophagus: the place where peristalsis takes place
small intestine: area of the digestive tract where most nuturients are absorbed
stomach: area of the digestive tract that follows the esophagus
large intestine: area of the digestive tract where mostly water is absorbed
Explanation:
peristalsis: so the food can move down towards your stomach, independently of gravity
pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes
small intestine: it is really really long -> more time to absorb nutrients
large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
