A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. Dichotomous keys always give two choices in each step.
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)
This explanation and his theory were not widely accepted. Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together, suggesting some schism in the past.
<span>Continental drift was really not allowable as even an accepted theory until the 1950s. Most geologists accepted the theory as quite possible before 1970. Several factors point to the acceptance of the continental drift theory. </span>
<span>Fossil records from separate continents, particularly on the outskirts of continents show the same species. As well mineral specimens along the supposed break lines of the continents are nearly identical. Some identical species exist on certain continents, like an earthworm common to both Africa and South America suggesting the species could not have spontaneously arisen on both continents without some variations hope this helps</span>
The correct option is ZYGOTE.
In humans, a zygote refers to a fertilized eukaryotic diploid cell that is produced as a result of fertilization process that occur between a male and female gametes. This cell contains all the genetic data that is required for the growth and development of a complete human being.The zygote is the first stage in the development process of a genetically unique organism that is genetically different from its parents.
Answer:
Nematocysts, the most widely used term to describe the “stinging capsules” characteristic of the phylum Cnidaria, constitute the best-studied and most diverse group of cnidae, the secretory products of cnidocytes. All cnidae consist of a collagenous capsule containing an eversible tubule.
