Answer:
The fossil record supports a "biological" type of evidence.
Explanation:
<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>
When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.
<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.
The molecule that is the primary source of energy in all cells is ATP, which is definitely not a macromolecule. Other primary sources of energy include other sugars, proteins, and fats. Hope this answers the question. Have a nice day.
Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
Answer:
The answer is option B. autotrophs
Explanation:
Decomposers release nutrients like nitrogen and carbon dioxide as well as water when they feed on dead plants and animals. Decomposers include fungi, bacteria and earthworms.
These nutrients are released into air, soil and water and serve as nutrients for autotrophs. Autotrophs produce their own food from sunlight energy, water and carbon dioxide. Example include green plants; which by the process of photosynthesis produce their own food using carbon dioxide and soil nutrients.
