<span>The correct answer is B. As one parent cactus is dominant heterozygous, and another is homozygous recessive, half of the progeny will bear long needles (as they carry dominant allele L), and hald will bear short needles (As they carry both recessive alleles).</span>
Answer:
1)the process being studied in the picture is transpiration I guess
3)the pot is covered with plastic sheet to trap the water (vapour) which is being evaporated
Answer:
And over time, volcanoes made from low lava viscosity are wide and have a shallow slope; these are known as shield volcanoes. Classic examples of shield volcanoes are Mauna Kea and Mauna Loa in Hawaii, as well as Olympus Mons on Mars. When lava has a high viscosity, it's very thick and doesn't flow very well at all.
9,600 cubic miles
Mauna Loa is the largest volcano on Earth with an estimated volume of 9,600 cubic miles (40,000 cubic kilometers). It makes half of the area of the Island of Hawaii. Mauna Loa began to form nearly a million years ago. There is a caldera, Mokuaweoweo, at the summit and rift zones extend to the northeast and southwest.
Explanation:
Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.
Answer:
Option A, The animal can only live in Australia
Explanation:
At present the Koala are found in several states of Australia such as
a) Queensland
b) NSW
c) Victoria
d) South Australia
Though the Koala is found on the eucalyptus trees of the temperate rain forest , they are only found in Australian geographies . There are several other place on planet earth where there is rainforest with eucalyptus trees and temperate climate, even though the Koalas are limited to Australia.
Hence Option A is correct.
