Answer:
Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-
Original fossils that are not very old. e.g. teeth, skeleton, shells.
Frozen fossils
less permanent fossils
casts, molds, and prints - wings, skin, leaves, etc.
The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.
e.g. Archeopteryx is the connecting link between the reptiles and birds.
The modern horse Equus have several ancestor species, we came to know from the fossil records.
The fossil record shows the evolution of humans and their ancestors.
Answer:
The process of erosion uses weather, water, and plants to break down the ground on earth so that craters become virtually nothing. ... The Earth's gravity is stronger than the moon's, so it attracts more space debris than the moon does.
Primarily because earths' atmosphere disintegrates many meteorites before they reach the Earth. Secondarily because earth's more active tectonic motions delete them
Explanation:
Answer:
It is expected to observe individuals exhibiting green, yellow, blue, and white colors in a phenotypic ratio of 9:3:3:1, respectively.
Explanation:
This example is a classic case of a dihybrid cross involving two unlinked genes that differ in the same observed trait. In this case, the genotype double homozygous recessive is white, while the presence of one dominant allele in one of these genes results in individuals with either blue or yellow color. Finally, the presence of two dominant alleles results in individuals with blue color.
Phenotypic and genotypic ratios:
gene 1 two alleles U u
gene 2 two alleles N n
Cross:
UuNn x UuNn
uunn: white color (1/16)
U_nn: yellow color (3/16)
uuN_: blue color (3/16)
U_N_: green color (9/16)
Echinoderms are more closely related to human than to a jellyfish because they are biltarian.
