Most water molecules that cross the plasma membrane do so by diffusion through aquaporins.
Aquaporins (AQP) are essential membrane proteins that act as conduits for the passage of water and, occasionally, tiny solutes. Animals, plants, and microorganisms all have them preserved in aquaporin. Each aquaporin molecule has a pore in its centre, according to structural investigations of the molecules.
Diffusion is the movement of molecules along a concentration gradient from a region of greater concentration to a region of lower concentration.
The definition of diffusion is the transfer of individual molecules of a material from a region of higher concentration to a region of lower concentration over a semipermeable barrier in diffusion.

Humans often like to help wild animals survive better. A marine biologist decided to feed Bruce’s pups and placed medicine in the food to prevent the pups from contracting an infectious disease. This helped more of Bruce’s offspring survive into adulthood. Eventually, the marine biologist moved after Bruce’s offspring reached adulthood. On the other hand, Chum’s offspring survived due to an inheritable trait that made them more resistant to infections.
A. Would the medication given from the marine biologist be able to pass down from one generation to the next
B.Would Bruce’s pups or Chum’s pups produce a fitter generation of pups? Explain your answer.
A. The medication given from the marine biologist would not be able to pass down from one generation to the next.
B. Chum’s pups would likely produce a fitter generation of pups because they have an inheritable trait that makes them more resistant to infections, which would give them a survival advantage.
Who is a marine biologist?
This refers to the study of biological oceanography and the fields related to chemical, physical, and geological oceanography to understand marine organisms. Marine biology is a very vast area of study therefore, researchers select a particular area of interest and specialize in it.

True/false: the zona pellucida is formed as the follicle becomes a secondary follicle.
It is true that the zona pellucida is an extracellular matrix that surrounds the oocyte (immature egg) and is formed as the follicle develops from a primary follicle to a secondary follicle.
What is follicle?In biology, a follicle is a small, spherical structure that contains an egg (or oocyte) and is found in the ovaries of female animals, including humans. Follicles develop in the ovary in response to hormonal signals, and each follicle contains a single immature egg that has the potential to develop into a mature egg that can be fertilized by a sperm. During the menstrual cycle, follicles grow and mature in response to the hormones estrogen and luteinizing hormone (LH) until one dominant follicle is selected to release a mature egg during ovulation. The remaining follicles will typically degenerate. In assisted reproductive technology (ART), multiple follicles can be stimulated to grow and develop using hormonal medications, in order to increase the chances of obtaining multiple eggs for fertilization.

A burn caused by boiling water causes proteins inside your cells to lose their functions. Explain why the high temperature causes this to happen? A.The increased temperature disrupts covalent bonds such as peptide bonds which causes the proteins to lose their primary structures and abilities to catalyze reactions. B.The increased temperature disrupts weak interactions such as hydrogen bonding which causes the proteins to lose their primary structures and abilities to catalyze reactions. C.The increased temperature disrupts weak interactions such as hydrogen bonding which causes the proteins to lose their tertiary structures and abilities to bind specific molecules. D.The increased temperature disrupts covalent bonds such as peptide bonds which causes the proteins to lose their tertiary structures and abilities to bind specific molecules.
C) The increased temperature disrupts weak interactionses such as hydrogenn bondding which causes the proteins to lose their tertiary structures and abilities to bind specific molecules.
Proteins are complex, three-dimensional molecules that are made up of long chains of amino acids held together by peptide bonds. The sequence of amino acids determines the protein's primary structure, while its final folded shape is determined by interactions between amino acids that create the protein's secondary, tertiary, and quaternary structures. These structures are held together by a variety of weak interactions, including hydrogen bonds, ionic bonds, and Van der Waals forces.
When a burn caused by boiling water occurs, the high temperature causes the hydrogen bonds and other weak interactions that hold the protein's tertiary structure together to break. As a result, the protein loses its three-dimensional shape, which is critical for its ability to perform its functions. This can cause the protein to become denatured, which means that it has lost its ability to bind to specific molecules or catalyze chemical reactions. Denaturation can also cause the protein to aggregate or clump together, which can interfere with cellular processes.
In summary, the high temperature caused by a burn disrupts the weak interactions such as hydrogen bonding that hold the protein's tertiary structure together. This leads to the protein losing its shape and function, and becoming denatured.

The colloid osmotic pressure in the capillary is caused by __________.
a) proteins in the blood
b) blood pressure
The colloid osmotic pressure in the capillary is caused by proteins in the blood.
The correct option is option a.
Colloid osmotic pressure, or the COP, is basically defined as the osmotic pressure which is exerted by the large molecules and basically serves to hold the water within the vascular space. This pressure is primarily created by the plasma proteins, namely the protein albumin, which is not able to diffuse very readily across the capillary membrane.
Inadequate amount of colloid osmotic pressure can end up contributing to the vascular volume loss as well as peripheral edema. Normal colloid osmotic pressure is approximately 20 mmHg. Patients who have the colloid osmotic pressure values less than 15 mmHg are at a possible risk for peripheral edema. COP is measured directly with the help of a colloid osmometer.

name two organelles that operate partially autonomously within the cell and share much in common with bacteria?
Two organelles that operate partially autonomously within the cell and share much in common with bacteria are mitochondria and chloroplasts.
Both of these organelles are believed to have originated from free-living bacteria that were engulfed by an ancestral eukaryotic cell, and over time, developed a mutually beneficial relationship that allowed them to survive and thrive within the cell.
Mitochondria are responsible for energy production in the cell, and play a critical role in cellular respiration. They have their own DNA and ribosomes, and are capable of reproducing independently of the cell. Chloroplasts, on the other hand, are responsible for photosynthesis in plant cells, and are also capable of reproducing independently of the cell. Like mitochondria, chloroplasts have their own DNA and ribosomes, and share many similarities with free-living photosynthetic bacteria.
Both mitochondria and chloroplasts are thought to have evolved from bacteria through a process called endosymbiosis, in which one organism lives inside another and eventually develops a mutually beneficial relationship. This process is thought to have played a critical role in the evolution of eukaryotic cells, and has led to the development of two organelles that operate partially autonomously within the cell, and share much in common with bacteria.
