The correct answer is (D)
Junipers belongs to genus Juniperus and are coniferous plants. These plants are widely distributed in northern hemisphere, from Arctic, south to tropical Africa and from Ziarat to Tibet, and in mountains of central America.
Juniper is a shrubs and grow densely over an area, shrubs are a great way to deter foot traffic through an area( another contributor to soil erosion). It helps to prevent soil erosion and are easy to grow plants.
Correct answer: A) bio-geographic isolation affects the random changes that take place within gene pools
The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.
The mixing of there genes within the same species is separated by the geographical barrier.
The barrier allows the mating of the species in a different way as compared to the previous one.
The sperm plasma then fuses with the egg's plasma membrane, the sperm head disconnects from its flagellum and the egg travels down the Fallopian tube to reach the uterus. In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
Answer:
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
Explanation:
Review the diagram, which shows a sedimentary sequence.
What could cause a sea-level change that would result in this sedimentary sequence?
a Melting ice caps change the quantity of ocean water, and rock made of calcium carbonate forms the top layer.
b Freezing temperatures change the quantity of ocean water, and rock made of larger grains forms the top layer.
c Rising temperatures change the density of ocean water, and rock formed in still waters appears in the upper layer.
d Tectonic activity changes the shape of the ocean basin, and rock formed in the deep sea appears in the upper layer.
The answer is B. We don't always have exact proof but our observations tell us more than we already know.
