What did Mendel's cross-pollination of pea plants prove?
A. Inherited factors combine in offspring to create entirely new characteristics.
B. Each parent only passes on one-half of its hereditary factors to each offspring.
C. There is no such thing as a true-breeding plant; they all have hidden factors.
D. It takes four generations of offspring to identify the parents' factors.
Answers
Answer:
B. Each parent only passes on one-half of its hereditary factors to each offspring.
Explanation:
Pea plants have both male and female reproductive organs. As a result, they can either self-pollinate themselves or cross-pollinate with another plant. In Mendel's experiments, he was able to cross-pollinate purebred plants with particular traits and observe the outcome over many generations.
As a little fun fact; as we know, both human parents have 46 chromosomes, and when reproduction occurs, they both give half of their chromosomes (23) to their offspring!

At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.

1.How do wavelength and frequency compare on the electromagnetic spectrum?
2.What are the different forms of radiation on the electromagnetic spectrum?
3.How is the electromagnetic spectrum used to examine astronomical objects?
Answers
Answer:
In physics, electromagnetic radiation consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.
Explanation:
2. There are radio waves, microwaves, infrared waves, visible light waves, UV (ultraviolet waves), X-rays, and gamma rays.
3. The electromagnetic spectrum deals with light on a scale from blue to red, with blue being the closest to the observer and red being the farthest from the observer. When scrutinizing astronomical objects, scientists can use the electromagnetic spectrum to hypothesize the distance a given object is from Earth.

Why would an organism prefer aerobic respiration as opposed to anaerobic respiration (fermentation)?
Answers
Answer:
Advantages of Aerobic Respiration
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
Explanation:
Mark as brainlest answer!Anerobic respiration will produce 36 ATP faster than aerobic, but it will also produce lactic acid, which is toxic for cells (hint- it’s an acid)
This is why an organism would prefer aerobic respiration. Anaerobic fermentation would also produce toxic lactic acid.

When relative humidity is 100%, the two thermometers register the same temperature. However, at 50% humidity, the wet bulb thermometer registers a lower temperature than the dry bulb thermometer. Why do you think the spinning motion cools the wet bulb thermometer when there is less humidity in the air?
Answers
Humidity likes to hold onto heat. The less humidity in the air the more the heat can be dissipated.
What do you mean by humidity?Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On the weather reports, humidity is usually explained as relative humidity.
Humidity is the measure of the level of moisture vapor suspended in the air around you. Although you can't see it, it's still there. The ideal relative humidity for health and comfort is somewhere between 30-50% humidity.
When the humidity level increases along with temperature, it's harder for the moisture to dry, and you feel warmer. When the air indoors is 75 degrees and the humidity is 30 percent, the air actually feels like 73 degrees.
