Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radio metric dating and categorize them to determine the evolutionary relationships between organisms

What are the interacting spheres of the earth and what is cycled between these spheres?
Answer: The Earth's Carbon Cycle is the biogeochemical exchange of carbon between the earth's five main physical “spheres”—atmosphere, biosphere, pedosphere, hydrosphere and lithosphere.
Explanation:
cause in space spheres is like ice that freezes in outer space
The interaction spheres of the earth are the atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere.
What are interacting spheres?Within the Earth's crust are four interconnected sections known as “spheres”: the lithosphere, hydrosphere, biosphere, and atmosphere. The spheres are so intertwined that a change in one sphere frequently results in a change in one or more of the others.
The Earth's Carbon Cycle is the biogeochemical exchange of carbon between the earth's five main physical “spheres”—atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere.
These four subsystems are referred to as "spheres." They are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living things), and the "atmosphere" (air). Each of these four spheres is subdivided into sub-spheres.
Therefore, the atmosphere, biosphere, pedosphere, hydrosphere, and lithosphere are the earth's interaction spheres.

D. Sodium
Answer:
C. Oxygen

This study reveals such a “photoelectric device,” where semiconducting Fe and MN (oxyhydrogen) oxide-mineral coatings are found to overlay vast expanses of natural rock/soil surfaces and exhibit highly responsive and stable photon-to-electron conversion.
What type of rock is limestone? Describe how a limestone rock is likely to change over a long period of time.
Answer:
Explanation:
Most limestones actually start as calcium carbonate mud or shells precipitated by organisms in reefs or shallow shelf regions - the biosphere. Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic CO2 (in the atmosphere).

Answer:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.

How does the moon cause tides?
The pull of the moon on Earth causes the water level on the shores to fluctuate.
The moon's gravitational pull acts on Earth.
The moon dries up Earth during different times of the month.
As the moon's gravity pulls on Earth, the ocean water is pulled toward it.
The moon pushes down on Earth and causes the water to rise.
Answer: 1, 4, 5
Explanation:
The moon always pulls on the tides, and in certain moments like the equinoxes the moon will set a patterned tide for the rest of the month, since the moon is being flung around in earths orbit, its gravity causes it to pull on the most flucuate object on earth: water. And if you have glass of water then put your hand into it you will see how your hand displaces the water.!
Could anybody help me on this please
Answer:
The term genotype refers to the genetic characteristics of an individual. Many genes have different variations, which are called alleles. As we inherit genes from both of our parents, we inherit one allele from each of them. The combination of alleles we possess is in fact our genotype.
The term phenotype refers to our physical characteristics. They are heavily influenced by our genotype, but they can also be affected by environmental factors (unlike the genotype).
As an example of genotype, we can mention eye color. Brown eyes are a result of dominant alleles (B), while blue eyes are a result of recessive alleles. If a person has one (Bb) or two dominant alleles (BB), their eyes will be brown, and if they have both recessive alleles (bb), their eyes will be blue.
As an example of phenotype, we can mention skin color. The amount of melanin we produce will depend on our genotype. A person whose skin cells produce more melanin will have darker skin. However, our melanin can start getting darker after longer exposure to UV light, which results in skin darker than what is dictated by our genotype.

Why do fish and frogs lay eggs in hundreds whereas a hen lays only one egg at a time?
Answer:
bc there eggs are tinnier then a hens egg
Explanation:
Answer:
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.

The drug colchicine inhibits the formation of spindle fibers during mitosis if you treat diving plant cells with colchicine what would you expect the results to be
Answer:
Chromosomes would divide in interphase and enter mitosis. However, the spindle apparatus would not form, so the chromosomes would end up in the metaphase form and no further mitotic events would take place.

In sex-linked traits, sons get their traits from the female.
True
False
Answer:
False
Explanation:
A sex-linked is any phenotypic trait associated with one or more genes located on sex chromosomes, i.e., on the X chromosome and/or the Y chromosome. In humans, females have two X chromosomes, whereas males have one X chromosome and one Y chromosome. In humans, sex-linked traits are often associated with recessive diseases caused by mutations on the X chromosome, although there are exceptions to this rule. In consequence, if a disease is associated with a mutation in the X chromosome, males will have more chances to be affected because males have a single copy of the X chromosome.
