"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.
Answer:

(1) Marine Chronometer In the early 18 th century, knowing your whereabouts on the face of the globe was difficult. As the world’s greatest global power, Britain was extremely keen to remedy that.

Answer: Ascomycota
Explanation:fungi are eukaryotic organisms that lacks chlorophyll,roots ,stems and leaves.they feed by decaying death matter and some exist as symbionts.they are found in trees,soil,burnt grass etc.
Fungi may be Unicellular or multicellular and possess whitish and threadlike filaments called hyphae.these hyphae forms a mass called mycellium,which is the main body.
Fungi reproduce asexually through spores.
The Ascomycota is a group of fungi also called sac fungi.their spores are formed in a sac , called ascus.the spores are eight in one haploid spores as they undergo mitotic Division to produce eight nuclei in the same ascus.
Upon maturity,the spores escape through a hole in the ascus and germinate when the fall on favourable places.
