I KNOW IT LOOKS ALOT BUT ITS 3 SMALL ANSWERS SEPERATED 1) As Charlotte watches her popcorn pop in the microwave, she wonders why she can’t see the energy that is heating up the kernels. Why can’t she see the microwaves that are creating the heat?

The energy level of microwaves is too high for us to detect with our eyes
Microwaves are moving too slow for our eyes to detect
The wavelength is too long for us to see with our eyes
Microwaves are moving too fast for our eyes to detect

2) When solar radiation crosses space and moves toward Earth, it consists of many types of radiation. Together, these radiation types are known as the electromagnetic spectrum. Which of the following properties differentiates among the different types of radiation found in the electromagnetic spectrum?

amplitudes
wavelengths
temperatures
chemical makeup

3) According to the (EM) spectrum diagram, what type of radiation has a larger wavelength than those found in the visible light spectrum?

Ultraviolet Light
Infrared Light
Gamma Ray
X-Ray

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

just here for the other one bc they put up with u

bc blah
