Answer:
you just draw what the question asks you to do.
Explanation:
The right option is; A. windblown sand cutting and polishing exposed rock surfaces
Abrasion is best described as windblown sand cutting and polishing exposed rock surfaces.
Abrasion is a process of erosion which occurs when materials such as soil or rock is removed and wears away at a surface over time. The concentration, hardness, speed and mass of the moving particles are the factors that determine the level of abrasion. Abrasion generally can be caused in four ways which are; by wind, by ice or glaciation, through the action of waves, and by rivers. Abrasion can be found on rocky mountains, on cliffs, at beaches, streams, and beneath glaciers.
Answer:
Yes.

Yes, all life on Earth depends on sunlight for obtaining energy and also shares a common ancestor of all organisms that lives on the land surface or in the oceans. Sun is the major source of energy through which plants produces food for itself and for other organisms. All the organisms have common ancestors which evolved with the passage of time when the change occurs in the environment and is responsible for the diversity of organisms.
Answer:
Phenotypic ratio= 1 Brown : 1 Gray
Explanation:
Genotype of brown snake= BB
genotype of gray snake= Bb
A cross between brown (BB) and gray (Bb) snake obtains progeny in following phenotypic ratio= 1 Brown : 1 Gray
Here, the heterozygous parent, gray snake (Bb) forms two types of gametes in 1:1 ratio while the homozygous dominant parent, brown snake (BB) forms only one type of gamete.
Lactose because it is a sugar made up of galactose and glucose.
