The correct answer is D. Mitosis. Mitosis is a type of cell division that results in two identical daughter cells, and does not increase genetic variation.
Crossing over, random fertilization, independent assortment and mutation, however, all increase genetic variation by introducing new combinations of alleles.
Crossing over occurs during meiosis, when chromosomes exchange genetic material. Random fertilization results in the creation of unique combinations of alleles in each offspring. Independent assortment occurs when different chromosomes are not inherited together. Finally, mutation introduces new alleles into the gene pool.

where in the digestive system are protease enzymes secreted?
Answer: In humans, proteases are mainly present in pancreatic juice and gastric secretions to break down dietary proteins. Trypsin and chymotrypsin are secreted by the pancreas and pepsin is secreted by the chief cells in the stomach.
Explanation:
Proteolytic enzymes or proteases catalyze the breakdown of proteins into shorter polypeptides or amino acids. They undergo proteolysis by hydrolyzing peptide bonds. Also, they are involved in various biological functions like protein catabolism, cell signaling and digestion.
Protease is produced in the stomach, pancreas, and small intestine.It is produced in the gastric chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. Pepsin is an aspartic protease, using a catalytic aspartate in its active site. Enzymes are secreted from our salivary glands, 1 and then from the cells lining our stomach, pancreas, and large and small intestines. Different types of enzymes are secreted depending on the types of foods that we eat.
Most of the chemical reactions occur in the stomach and small intestine. In the stomach, pepsin is the main digestive enzyme attacking proteins.Proteases enzymes allow for proteolysis, the process that breaks the long, chainlike molecules of proteins so that they can be digested. Proteases are produced by the pancreas, and they are also found in some fruits, bacteria and other microbes

While traveling through the rain forest of Peru, you are introduced to a rare and exotic plant. You discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. If administered, what affect would this toxin have on the reabsorption of glucose
While traveling through the rain forest of Peru, we are introduced to a rare and exotic plant. we discover that it contains a toxin that blocks the reabsorption of sodium ions from the proximal tubule. If administered, the toxin would significantly decrease the amount of glucose reabsorbed.
Tubular reabsorption always happens via the paracellular route. It involves carrier-mediated transport. It moves water and solute from the blood to the filtrate.
Reabsorption from PCT - The PCT is responsible for reabsorbing 50–60% of the glomerular ultrafiltrate. Thus, it is a site for high volume reabsorption, but not for regulation of the final composition of the urine.
Sodium absorption varies widely under conditions of Na+ excess or depletion and is primarily regulated by the hormones aldosterone and vasopressin, both of which increase renal Na+ absorption by acting on the principal cells of the kidney.

A. 25%
B.50%
C.100%
100%. In a cross between two plants that are both true-breeding for purple flowers, all of the offspring will have purple flowers.
What do you mean by true-breeding?
True breeding is a term used to describe organisms or varieties of organisms that always produce offspring with the same characteristics as the parent generation when bred together. This is also known as pure breeding or inbreeding. This is achieved by breeding only related individuals that share the same desirable traits.
This is because the purple flower trait is dominant, and the white flower trait is recessive. Therefore, all of the offspring will have the dominant purple flower trait, and none of them will have the recessive white flower trait.

What joints are condyloid joints?
A condyloid joint is a type of synovial joint within an ellipsoidal cavity of the other bone.
An ovoid convexity on one articular surface of the bone articulates with another bone with an ellipsoidal hollow. This joint can rotate but not move. Jaw and finger joints, for example, are condyloid joints. Condyloid joints are also known as condylar joints, bicondylar joints, or ellipsoid joints.
The articular capsule is found between the two linked bones in condyloid joints. The synovial joint is protected by articular cartilage. Certain ligaments around the joint give support. They also aid in injury prevention by restricting mobility.
Condyloid joints, like saddle joints, provide for two degrees of freedom of movement. Such joints permit movement such as abduction/adduction and flexion/extension (circumduction).
The ball and socket joint allows axial rotation but not the condyloid joint. Condyloid joints, in other words, have non-axial motions. Due to the oval form of the joints, however, minimal circumduction may be achieved at such joints.

What are inherited traits give any two examples of it in humans?
Traits that are inherited in humans from their parents are hair color, eye color, etc.
Some physical traits are determined by a single gene, while other traits manifest due to the expression of two or more genes. These genes are expressed to varying degrees and produce specific versions of physical traits.
Some of the characteristics that are passed from parents to offspring are caused by combinations of genes that are expressed and do not always follow dominant or recessive inheritance patterns.
More than 20 genes play a role in controlling the proteins involved in expressing hair color. The protein then activates the production of the two pigments responsible for hair color pheomelanin for red hair and eumelanin for blonde, black, or brown hair. While one gene can determine black or brown hair, the expression of several genes determines colors that range from the lightest blonde to black or a combination of colors, such as auburn.
Eye color is determined by variations between the genes involved with melanin. The gene that activates the production of large amounts of melanin produces brown eyes and small amounts of melanin produce blue eyes, with shades of green and hazel falling between the two ends of the spectrum. Eye color is primarily determined by two genes, with several other genes playing a lesser role in how eye color is expressed.

Heartburn, also known as pyrosis, cardialgia, or acid indigestion, is a burning feeling in the upper central belly or central chest. Heartburn is often caused by the regurgitation of stomach acid into the esophagus (gastric reflux). It is the most common sign of gastroesophageal reflux disease (GERD).
Belching, nausea, squeezing, stabbing, or a feeling of pressure on the chest are all classic characteristics for heartburn, in addition to burning. The discomfort usually starts in the chest (just beneath the breastbone) and can spread to the neck, mouth, or arm angle.
