Answer: B. Genes
Explanation:
Got it right on the test.
The correct answer is option C, that is, the presence of the nuclear membrane.
Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.
Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.
Answer:
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Explanation:
Answer: Information stored in DNA must be translated into functional products.
Explanation: DNA is a short form of deoxyribonucleic acid. DNA is a type of nucleic acid. There are two types of nucleic acids: DNA and RNA (ribonucleic acid).
DNA is a double-stranded helical molecule that contains the complete information for the synthesis of a functional gene product. The functional gene product is usually a protein.
DNA is first copied into a messenger RNA (mRNA) in a process known as transcription. This process is catalyzed by the enzyme RNA polymerase. This process occurs in the nucleus.
The mRNA leaves the nucleus to the ribosome where it is used to produce a protein. This process is called translation and occurs in the ribosome. The protein is the functional product that expresses its function in the organism.
Answer:
B. the energy production in the sun.
Explanation:
The sun ngenerates its energy by nuclear fusion of hydrogen nuclei into helium.
