What happens when oxygen, carbon dioxide and glucose molecules diffuse across the cell membrane? Explain in your own words
Answer:
Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

which description of skeletal cartilage is incorrect?
The incorrect description is that Costal cartilages reinforce airways and support the external nose
The options were omitted but the complete question is :
Which description of skeletal cartilage is incorrect
Fibrocartilages are able to withstand both pressure and stretch.
Costal cartilages reinforce airways and support the external nose.
Elastic cartilages are able to tolerate repeated bending.
Articular cartilages cover the ends of most bones at moveable joints.
Costal cartilages are said to be at the anterior extreme of a rib cage. Their function is to give the ribcage a flexible structure and connect the ends of the ribs to the sternum. Respiratory cartilages are present in the Trachea and are responsible for flexible inhalation and exhalation thereby reinforcing airways and providing support to the structure of the nose.

Answer:
Nuculear Fission.
A process in which a large nucleus splits into two or more parts is called nuclear fission.
What is nuclear fision?The term nuclear fission refers to the breaking apart of a large nucleus to give daughter nuclei with the accompanying release of energy. We have to note that usually the nucleus is bombarded by a small particle.

Answer:
A student is looking through a microscope at some cells of an onion root tip. Many of these cells are undergoing division since the root tip grows quickly and requires more cells. Which cell is going from metaphase into anaphase? W X Y Z
It's y
The cell Y is transitioning from metaphase to anaphase.
What is metaphase?
The chromosomes are at their second-most compacted and coiled state during the mitotic stage of the eukaryotic cell cycle, known as metaphase. These chromosomes, which contain genetic material, align in the cell's equator before being divided into the two daughter cells.
A phase of cell division known as "metaphase" (mitosis or meiosis). Individual chromosomes are typically dispersed throughout the cell nucleus. During metaphase, the cell's nucleus disintegrates and the chromosomes condense and migrate toward one another, aligning in the middle of the dividing cell.
The duplicate genetic material existing in a parent cell's nucleus is divided into two identical daughter cells during the third stage of mitosis, known as metaphase.

the lysis of red blood cells in blood agar is indicative of the presence of which enzymes?
cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
Explanation: One cause of hemolysis is the action of hemolysins, toxins that are produced by certain pathogenic bacteria or fungi. Another cause is intense physical exercise. Hemolysins damage the red blood cell's cytoplasmic membrane, causing lysis and eventually cell death.
BAP assesses an organism's ability to produce hemolysins, enzymes that damage/lyse red blood cells (erythrocytes). The degree of hemolysis caused by these hemolysins aids in the identification of members of the genera Staphylococcus, Streptococcus, and Enterococcus.
What hemolytic pattern does S aureus shows on BAP?On blood agar plates, colonies of Staphylococcus aureus are often encircled by zones of clear beta-hemolysis. The golden appearance of colonies of some strains is the etymological root of the bacteria's name; aureus meaning "golden" in Latin.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, causes hemolysis. Intense physical activity is another cause. Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.
The action of hemolysins, toxins produced by certain pathogenic bacteria or fungi, is one cause of hemolysis. Intense physical activity is another cause.
Thus, Hemolysins cause lysis and eventually cell death by damaging the cytoplasmic membrane of red blood cells.

#1Fish develop more slowly than chickens, mice, and humans.
#2Fish embryos cannot be distinguished from chicken embryos.
#3Mice and humans have no similarities during development
#4Humans are more closely related to mice than they are to chickens or fish
Answer:
#4 Humans are more closely related to mice than they are to chickens or fish.
Explanation:
If you compare the human embryo with the mouse embryo, you can tell they look very similiar, like in the way they curl up and in their eye placement/size. With the other two- fish and chickens- they look extremely different in comparison to the human embryo. The comparisons that i used before (eye placement/size and formation) I'll use as an example. They look nothing similiar to each other, therefore the answer is #4.
