"Identical twins are more similar on the trait than fraternal twins" would lead to the conclusion that genetic factors are important in the development of this trait.
<u>Option: C</u>
<u>Explanation:</u>
Research performed on identical or fraternal twins are twin investigations. We seek to expose the significance for characteristics, phenotypes and diseases of environmental and genetic factors. Twin work is considered a key instrument in the domains of behavioral genetics and material, from biology to psychology.
Fraternal or dizygous twins each share around 50 % of their DNA, just like any other parent. Since the twins are born into the same family they share other factors of their surroundings. The existence of a given genetic or phenotypic trait in just one component of a pair of twins called discordance offers a valuable insight into influence on such a trait on climate.
The access is most heavily limited by Climate
In an extremely dry and hot climates such as desert, it will be incredibly hard to access potable water because they evaporate really quickly
Meanwhile in a wet and cool climates such as rain forest, it will be extremely easy to access potable water
Answer: B). fertilization, diploid
Explanation: During fertilization, the sperm cell (a gamete) fuses with an ovum or egg (a gamete) to form a zygote. Each of the gametes have haploid number of chromosomes (23 chromosomes) and they fuse to produce a zygote with a diploid number (46 i.e., 23 pairs) of chromosomes.
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers. B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash. C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population. D) The hawks has to have the smallest population.
