Answer:
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.
Answer:
8
Explanation:
I am assuming that this organism reproduces sexually. The body cell of the offspring will be the same as the parent. The reproductive cell of the organism will have half the amount of chromosomes as the body cell.
So if the parent has 8 chromosomes in its body cells then the offspring will have 8 chromosomes in its body cells.
Answer: Nitro blue tetrazolium is a chemical compound composed of two tetrazole moieties. ... NBT serves as the oxidant and BCIP is the AP-substrate (and gives also dark blue dye).

Explanation:
Answer:
number of nitrogen bases
Explanation:
<em>The correct answer would be the number of nitrogen bases.</em>
<u>A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.</u>
Mutation can occur in a variety of ways including:
<em>1. Deletion of nucleotide base sequence in the DNA</em>
<em>2. Addition (insertion) of nucleotide base sequence in the DNA</em>
<em>3. Duplication of nucleotide sequence in the DNA</em>
<u>A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.</u>
Hence, the correct option is number of nitrogen bases.
Living things are made of types of molecules, known as macromolecules.
There are four major classes of biological macromolecules:
carbohydrates
lipids
proteins
nucleic acids
Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
