Cell transport describes the passage of a material across a cell membrane. The material has the ability to enter or exit cells. Different substances travel through the cell membrane or plasma membrane.
What is cell transport called?Material moving across cell walls is referred to as cell transport. Both inactive and active cell movement are involved. Active transport needs energy to operate, whereas passive transport doesn't. Osmosis, assisted diffusion, and diffusion take place during passive movement.
In a cell, there are four different kinds of transfer systems. These are main active transport, secondary active transport, facilitated diffusion, and straightforward diffusion.

Cells are placed in a solution that causes them to absorb liquid until they burst. When more water is removed from the solution, newly added cells do not burst. The original solutions was ________ , while the second was ________ to the cells.a. hypertonic; isotonicb. isotonic; hypotonicc. isotonic; hypertonicd. hypotonic; isotonic
Hypotonic and isotonic.
The original was Hypotonic because it grew. The second is Isotonic because they stayed normal. If the cells shrunk, they would be Hypertonic.
The original solution was hypotonic, while the second was isotonic to the cells. The correct answer is option d.
In a hypotonic solution, the concentration of solutes is lower outside the cell than inside the cell. This causes water to move into the cell through osmosis, causing the cell to swell and potentially burst.
Over a semipermeable membrane, a solution is referred to as a hypotonic solution if it contains less solute than other solutions with the same solute concentration. Such a solution results in a reduction in the concentration of solutes and complete water flow within the cell. This results in edema breaking down.
In an isotonic solution, the concentration of solutes is the same inside and outside the cell, so there is no net movement of water and the cell does not swell or shrink.
A solution that has the same osmolarity, or solute concentration, as another solution is said to be isotonic. Water will flow equally into and out of either solution if a semipermeable membrane is used to separate the two. We can say that the net flow is the same because the flow in and out is equal.
Therefore, the correct answer is option d. hypotonic; isotonic.

What is the length of the side of each of the smallest squares on your hemocytometer? biol 4100
The length of the side of each of the smallest squares on your Hemocytometer is 50 micrometers.
The hemocytometer (or haemocytometer) is a counting-chamber device that was initially created for counting blood cells.
Louis-Charles Malassez designed the hemocytometer, which consists of a thick glass microscope slide with a rectangular depression that produces a precise volume chamber. This chamber has a laser-etched grid of perpendicular lines. The gadget is meticulously built such that the region limited by the lines and the depth of the chamber are both understood. It is therefore feasible to count the number of cells or particles in a certain volume of fluid by watching a defined region of the grid, and hence compute the concentration of cells in the fluid overall, by observing a defined area of the grid. The Neubauer counting chamber is a popular type of hemocytometer.

during the yeast fermentation lab, why did glucose show a higher rate of fermentation than starch? multiple choice starch is a disaccharide. starch is a polysaccharide. glucose is a disaccharide. glucose is a polysaccharide.
During yeast fermentation lab, glucose shows a higher rate of fermentation than starch as : starch is a polysaccharide.
What happens in yeast fermentation?During the yeast fermentation, glucose is converted to ethanol and carbon dioxide by the action of yeast enzymes. Starch is a complex carbohydrate that is made up of many glucose units linked together in chain. In order for yeast to ferment starch, the starch must be broken down into component glucose molecules, which takes time and requires additional enzymes.
Therefore, glucose shows higher rate of fermentation than starch because it is already in the form of simple sugar that can be readily metabolized by yeast. Starch, being a polysaccharide, is more complex and hence requires more processing before it can be used by yeast for fermentation.

how does the distribution of starch compare with tparts of leaf in which carbon fixation reactions take place g
The distribution of starch in a leaf is closely related to the parts of the leaf where carbon fixation reactions take place. Starch accumulates in the mesophyll cells of leaves, which are responsible for carbon fixation through photosynthesis.
Starch is a carbohydrate that is produced as a result of photosynthesis and is stored in various parts of the leaf to provide energy for growth and development. The distribution of starch is directly related to the parts of the leaf where carbon fixation occurs. Starch accumulates in the mesophyll cells of leaves, which are responsible for carbon fixation through photosynthesis.
Starch accumulation is critical because it serves as a reservoir of carbohydrates that can be used to support other plant functions, such as growth, development, and energy production. Starch is stored in chloroplasts, which are organelles that contain the pigments responsible for photosynthesis. Carbon dioxide is fixed in the chloroplasts, resulting in the production of sugar, which is then converted to starch for storage.
The greater the rate of carbon fixation in the chloroplasts, the more starch will be produced, and the higher the accumulation in the mesophyll cells. The location of starch within the leaf can be determined by staining the leaf tissue with iodine, which produces a blue-black color when it comes into contact with starch.

Shortly explain the science behind gene therapy.
Answer:
Gene therapy is a medical technique that aims to cure diseases by changing a person's genetic material. Our genes are like a set of instructions that tell our cells what to do. Sometimes, these instructions can be wrong, and that can cause diseases. Gene therapy is a way of fixing those mistakes.
The process of gene therapy involves introducing new or modified genes into a person's cells to correct the faulty instructions. Scientists use different methods to do this, but the most common one is to use a modified virus called a "viral vector." This virus is engineered to carry the new or modified gene and infect the target cells, inserting the new gene into their DNA. Once the new gene is in the cell, it can produce the correct protein that was missing or defective, which can cure the disease.
Gene therapy can be used to treat a wide range of diseases, including genetic disorders like cystic fibrosis or sickle cell anemia, cancer, and viral infections like HIV. However, it is still a new field, and there are many challenges to overcome, such as making sure gene therapy is safe and effective and developing better ways to deliver the therapeutic genes to the right cells.

What is sickle cell anemia and how is it caused by your genes? Use the starter sentence below.
Sickle is caused by ____________
Answer:
Sickle cell anemia is caused by a genetic mutation in the hemoglobin gene.
Explanation:
Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. In sickle cell anemia, the mutation causes the hemoglobin to form abnormal, sickle-shaped cells instead of the normal round shape. These sickle cells are stiff and sticky, and they can block blood flow in the small blood vessels, leading to pain, infections, and organ damage. The mutation that causes sickle cell anemia is inherited from both parents, and it is more common in people of African descent but can also occur in other populations.
