Next, Mendel took the F1 progeny and allowed them to self-fertilize. In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. ... 1 out of 3 round pea plants from the F2 generation were true-breeding and produced only offspring with round peas.
Experimentation (or the experiments the scientist was doing for 10 years) could be wrong or done in an inappropriate way. The only way to know if the information is valid is by checking the way the experimentation (data) was done as well as making sure to check all other factors
Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.
- The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
- As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
- While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
- This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
- At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.

Peristalsis is the involuntary relaxation and constriction of the muscles of the digestive system which causes the movement of food in the digestive system. This is actually one of the reasons why you can eat upside down, however it is not advisable.
The answer is PERISTALSIS.
A Kidney/s: They are bean-shaped organs that filter waste products and urea from the blood. The filtering units of kidneys are called nephrons. Along with water, these waste products and urea are what makes up urine.
B. Ureters - These are thin tubes that connect the kidney and bladder. From the kidneys, the urine passes through the ureter down to the bladder. These ureters are just about 8 to 10 inches long. The ureters' walls tighten and relax to prevent back flow of urine.
C. Urinary Bladder - The bladder is a hollow and balloon-shaped. It collects the urine from the ureters. The bladder is held up by ligaments that are attached to the pelvic bones and other organs. The bladder has a sphincter that prevents leakage into the end point of the urinary system.
D. Urethra - It is a tube that allows the passage of urine out of the body. Men generally have longer urethras than women. In women, the urethra is about 2 inches long and in men, about 8 inches long.
