Answer:supports the body
facilitates movement
protects internal organs
produces blood cells
stores and releases minerals
Explanation:
The skeletal system in animals helps in their movement, support and to maintain their shape.In humans ,it consists of bones,which works closely with the muscular system.unlike worms and arthropods that have hydrostatic and exoskeleton respectively, humans have endoskeleton.the bones have the following functions;
*It allows the animal move . The skeleton provides support for the body and through the flexible joints ,the body is able to move
*The skeleton protects the internal organs of the body by protecting them against impact.for examples,the ribs protect the lungs and the skull protects the brain.
*Certain cells in the bone produce immune cell and important components of the bone
*The bones also regulate the level of calcium in the blood
The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.
Explanation:
The bacteria rapidly divide, the chances of mutation in the gene increases manifold.
The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.
These bacteria which survived and proliferated as the environment was in their favour.
Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.
The answer is B
C pairs with G, T pairs with A but in RNA T is replaced with U so A pairs with U
Photosynthesis<span> is plants taking in water, carbon dioxide, and light to make sugar and oxygen. This is </span>important<span> because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants.
Hope this helps</span>
Answer:
c. lobes
Explanation:
Brain lobes are divisions of the cerebral hemispheres, designated by the names of the surrounding cranial bones and covering them. The frontal lobe is located in the forehead region; the occipital lobe in the nape region; the parietal lobe in the upper central part of the head; and the temporal lobes in the lateral regions of the head above the ears.
Parietal, temporal and occipital lobes are involved in producing the perceptions resulting from what our sensory organs detect in the outer environment and the information they provide about the position and relationship to outer objects of different parts of our body.
