If you observed that the sperm of a bull could not fuse in a lab dish with the eggs of a cow, you would say that the bull and the cow showed gametic isolation.
What is gametic isolation?A type of isolation that occurs in many aquatic animals of different species. These species deposit gametes in the water, in the same place and at the same time, with fertilization occurring only between gametes originated by the same species.
Reproductive isolation mechanisms that operate prior to mating are called prezygotic reproductive barriers. These barriers are important, as they prevent individuals of different species from interbreeding and reproducing.

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

Which statement is true regarding the taxonomic system?
Charles Darwin was the primary creator of the current taxonomic system.
All of the past, extinct species have been cataloged.
The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.

Answer:
ATP functions as the energy currency for cells. ... The structure of ATP is that of an RNA nucleotide with three phosphates attached.
