Explanation:
Answer: increases the chance that deleterious and lethal recessive alleles will combine to produce homozygotes with harmful traits.
Explanation:
Unlike crossbreeding, inbreeding encourages the mating of organisms of same species; thus preventing the introduction of other desirable traits and a state of continuous monopoly in transmission of inherited traits (both beneficial and deleterious)
Answer:
The statement, that is, the fossil record does not contain any fossil remains of plants, only animals is false.
Explanation:
Any trace of past life is termed as the fossil. It can be an organism's remains like shells, plants, bones, or teeth. Any activity of an organism like burrows, footprints, and feces can be known as a fossil record. Five different ways by which the formation of a fossil takes place are natural casts, permineralization, trace fossils, amber preserved, and preserved remains.
The formation of a fossil distinctly takes place, however, the majority of them formed when an animal or plant dies in a watery environment and gets buried underneath the silt and mud. In the process, the soft tissues quickly get decompose and leave behind the shells or hard bones. With time accumulation of sediments takes place over the top and solidifies into a rock.
1. Temperatures are extreme; mostly high or very cold temps (only winter and summer it feels like). They have changed over years.
2. Polar ice caps (glaciers) are melting drastically.
3. Habitats/ecosystems such as the coral reef are suffering and are expected to disappear over the course of 10-20 years
