The fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life
descended from a common ancestor. Which of the following is evidence that justifies this claim? a. All organisms are made up of cells that contain energy-producing mitochondria.
b. All organisms are made up of cells that reproduce asexually through mitosis and meiosis.
c. The cells of all organisms contain DNA that is housed in a membrane-bound nucleus.
d. The cells of all organisms share common metabolic processes, such as cellular respiration.
c. The cells of all organisms contain DNA that is housed in a membrane-bound nucleus.
Explanation:
DNA is the genetic material found in the cells of living organisms. Among the characteristics of the DNA that makes up the genetic code, it is said to be nearly universal though. DNA is said to be the "blueprint of life".
This means that the DNA sequence that encodes protein and useful information is the same in almost all living organisms. Hence, the statement that "cells of all organisms contain DNA that is housed in a membrane-bound nucleus is the" justification that fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life.
A peninsula is mostly surrounded by mass around most of its coastline. It can also be referred to as a headland. The part that is not surrounded is connected to the larger continental landmass. Another example of the peninsula is the Korean peninsula and the Floridian Peninsula.
1. The group nearest the end or with the shortest stem of a phylogenetic tree has evolved most recently. In this case it is eutherians.
2. The group with the longest stem has been around the longest: fish
3. A direct common ancestor will share the same immediate line, like marsupials and eutherians. Fish and marsupials do not have a common direct ancestor.
A repeated series of independent experiments where there is only two possible outcomes (Normally called "Success" or "Failure") Examples: When you flip a coin. Out comes: head or tails Hope it helped :) Sorry if it was to late
