Answer:
A homozygous dominant trait can be described as a trait in which both the alleles of a gene are the dominant one. For example, the AA genotype of the 80 brown gerbils.
A heterozygous trait can be described as the trait in which one of the alleles is dominant and the other is recessive. For example, the Aa genotype of the 64 brown gerbils.
A recessive trait can be described as a trait in which both the alleles are recessive. For example, the aa genotype of the black gerbils.
The completed table is shown in the attachment.
For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.
For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.
I mean global warming is pretty fast ngl
