What is plasma membrane?
The boundary between a cell's inside and outside is created by the plasma membrane, which is a network of lipids and proteins. It is also known as the cell membrane plainly. The plasma membrane's primary job is to shield the cell from its surroundings. It controls the materials that enter and leave the cell and is semi-permeable. All living things have plasma membranes in their cells.Na/K pump across plasma membrane:
This protein pump, also known as the Na+/K+ pump or Na+/K+-ATPase, is located in the cell membrane of neurons (and other animal cells). In a ratio of 3 sodium ions out for every 2 potassium ions brought in, it functions to transport sodium and potassium ions across the cell membrane. The process aids in stabilizing membrane potential, and the pump is crucial in establishing the circumstances required for action potentials to fire.Hence, 700 Na+; 200 K+; 900 ATP and −200 charge differential (inside-outside) is the answer

Which one of the following aquatic plants grows completely submerged in water?a. water lily
b. lotus
c. water hyacinth
d. hydrilla
The aquatic plants that grows completely submerged in water is d. Hydrilla.
Hydrilla is a genus of aquatic plants that includes only one species, Hydrilla verticillata, though some botanists divide it into several. Hydrilla is an aquatic weed that forms large mats that can completely cover a pond. Diquat Herbicide has proven to be the most effective against Hydrilla, killing growths quickly.
Hydrilla outcompetes native submerged aquatic vegetation and can quickly fill a pond or lake, preventing boating, fishing, swimming, and other recreational activities from taking place. Despite being non-native and invasive, it provides high-quality habitat for fish and shellfish, as well as benefits to water quality.
It can tolerate lower light levels than most aquatic plant species, allowing it to start photosynthesizing earlier in the morning, giving it a competitive advantage. It spreads quickly through tubers and turions. Because there are no native predators that eat hydrilla, its growth is unabated.

degeneration of the distal portion of the neural process and the myelin sheath is called this type of degeneration
Degeneration of the distal portion of the neural process and the myelin sheath is called the Wallerian type of degeneration.
In the field of biology, Wallerian degeneration is a type of degeneration of axons that occurs due to an immune response caused by an injury.
As a result of Wallerian degeneration, the myelin sheath that wraps and protects an axon is destroyed. When the myelin sheath is destroyed, the axons are no longer able to transmit signals from one neuron to another. As a result, the whole of the neural communication process is disturbed.
However, this type of degeneration is recognized by the body within a short time and as a response, the growth of more axons is promoted with a protective myelin sheath.

in dogs, alleles c and c determine whether a dog has curly (cc), wavy (cc), or straight hair (cc). in a cross of a curly-haired dog with a straight-haired dog, what will be the phenotypic ratio of the offspring?
Answer: (cC)
Explanation: Curl (C) is governed by a change in one of the genes responsible for a structural protein in hair (keratin). The mutation again involves the substitution of a single nucleotide—this time, a T (thymine) is substituted for a C (cytosine). The substitution is believed to affect folding of the completed protein, leading to curled or wavy hair. Dogs with straight hair have two copies of the straight form of the gene (cc); dogs with wavy hair have one copy of the straight form of the gene and one copy of the curly form (Cc); dogs with curly hair are homozygous for the curly mutation (CC).

The repulsive forces would boost the energy of all the electrons on the metal equally if it were surrounded by a spherical field of electrons (physicists like to imagine things are spherical since it makes the calculation easier).
The magnetic characteristics of metals and metal salts were of interest to both scientists. They were aware that these attributes were connected to unpaired electrons. While compounds with just paired electrons are not attracted by magnetic fields, those with unpaired electrons are. Since the quantity of unpaired electrons depended on how the d electrons were filled, they were interested in the variables that affected the d electron configuration of transition metal salts.

Hydrolysis is a chemical reaction wherein water is used for the break down of chemical bonds existing between particular substances.
In hydrolysis, the water (H2O) molecules get attached to two parts of a molecule. One molecule of the substance gets H+ ion and the other molecule will receive the OH- group.
Polymers are usually broken down into monomers in hydrolysis.
Reaction of water with another compound results in the formation of two or more products.
Examples of hydrolysis are dissolving dissolving sulphuric acid in water or a salt of a weak acid or base in water where hydronium and bisulfate compounds are formed.

Through internal metabolic heat production, heterotherms maintain high body temperatures.
Heterotherms are organisms with a body temperature control range that lies between that an ectotherm and an endotherm. Some endothermic ('warm-blooded') small mammals and birds may lower their metabolic rate during a particular season or even time of day, causing their body temperature to drop and enter a condition of torpor. This saves small animals, like hummingbirds and some rodents, the relatively expensive expense of keeping a steady body temperature when there is a lack of food or other unfavorable circumstances. Partial endothermy is another name for this tactic. On the other end of the spectrum, certain creatures that are typically thought of as ectothermic (or "cold-blooded") have the capacity to generate heat internally for brief durations, momentarily boosting their body temperature to enable activity when the surrounding environment is chilly.

b. decrease in pH (acidosis) strengthens the hemoglobin-oxygen bond
c. increase in pH (alkalosis) weakens the hemoglobin-oxygen bond
d. increase in pH (alkalosis) strengthens the hemoglobin-oxygen bond
The correct option is Option a.
With the Bohr effect, more oxygen is released because: a decrease in pH (acidosis) weakens the hemoglobin-oxygen bond.
What is the Bohr Effect?The Bohr effect causes the muscles and tissues to release more oxygen when CO2 levels rise. This helps deliver oxygen to metabolizing tissue such as skeletal muscle, where it is needed most.
The Bohr effect is a result of the effect carbon dioxide has on hemoglobins affinity for oxygen.
As carbon dioxide increases, it combines with water to form carbonic acid. This increase in acid lowers the pH. The lowered pH then decreases hemoglobins affinity for oxygen, meaning hemoglobin lets go of oxygen more easily. As a result, more oxygen is released to the muscles and tissues that need it most.
Conversely, decreases in carbon dioxide will increase hemoglobins affinity for oxygen, meaning hemoglobin is less likely to release oxygen. Thus, the relationship between CO2 and hemoglobins affinity for oxygen can be described as an inverse relationship meaning when one goes one way, the other goes the other way.
