The answer is D. This means that is you have a determined amount of force (in newtons) being applied on an object of known mass (in kilograms), then to determine the acceleration of the object, divide the force by the mass (or multiplying the force with the inverse of the mass of the object). This behavior of objects is stipulated in Newtons/ second law. Increasing the force increases the acceleration while increasing the mass decreases the acceleration of the object. Acceleration is a vector quantity meaning it has magnitude and direction.
B. small sizes
C. varied shapes
D. methods of movement
Answer: The correct answer for the blank is A.biochemical diversity.
Bacteria can thrive in various environmental conditions such as hot springs, salt flat, polar ice caps because of their biochemical diversity.
For instance, the organisms belonging to the domain archaea ( such as methanogens) live in extremely harsh environmental conditions. They have ether linked lipids in their cell membrane ( unlike bacteria, which possess ester linked lipids) and do not have peptidoglycan in their cell membrane. This provides them an advantage to survive under harsh conditions.
Nucleic acids provide the blueprint for the construction of proteins, the third statement best describe the relationship between proteins and nucleic acids.
The primary information-carrying molecules in the cell are Nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two main forms of nucleic acids. DNA is the genetic substance of all free-living creatures and the majority of viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays a crucial part in activities such as proteinsynthesis.
The mRNA (messenger RNA) receives the genetic information of the proteins from the DNA (Deoxyribonucleic acid) and gives it to the ribosome (which generates proteins), so that the ribosome may produce proteins based on the 'blueprints' that came from the DNA.
Thus, the third statement best describes the relationship between proteins and nucleic acids.

Answer:
Simple diffusion is the process by which some atoms and molecules move directly across the cell membrane from an area of high concentration to an area of low concentration.
Answer:
chloroplast.
Explanation:
Chloroplasts are specialized organelles found in plant cells and some other organisms, such as algae. They are responsible for carrying out photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into glucose (energy) and oxygen.
Chloroplasts have a double membrane structure and contain their own DNA and ribosomes. They are green in color due to the presence of chlorophyll, a pigment that captures light energy for photosynthesis.
The presence of chloroplasts in plant cells allows them to produce their own food through photosynthesis, whereas animal cells do not possess chloroplasts and rely on obtaining nutrients from external sources.
In summary, chloroplasts are organelles found in plant cells but not in animal cells. They play a crucial role in photosynthesis, enabling plants to convert light energy into chemical energy and produce their own food
