Answer:
A. Photosynthesis
Explanation:
Photosynthesis is a process in plants produce food materials by absorbing carbondioxide from the atmosphere which decreases the concentration of carbondioxide in the atmosphere. In photosynthesis reaction, plant take water from the soil and carbondioxide from the atmosphere in the presence of sunlight produces glucose and oxygen. Glucose is stored in different parts of plant such as grains, stem and roots while oxygen is released in the atmosphere.
Answer:
Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.
Explanation:
False
Not always, some proteins are used in a variety. <span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. </span>
Answer:
A Origin
Explanation:
Sternocleidomastoid is the muscle found in the cervical and it’s the largest. It is responsible for the rotation and flexibility of the neck and is a very powerful and tissue-rich muscle.
The sternocleidomastoid muscle extends from the mastoid process of the temporal bone to the sternum and medial clavicle. When both sternocleidomastoid muscles contract, the head is flexed. The end of the muscle called ORIGIN connects to the sternum.
Answer:
e) All of the answers are correct
Explanation:
The first X-ray picture of DNA taken in 1952 by Rosalind Franklin using the X-ray crystallography technique revealed the helical shape of DNA. Based on this discovery, it was discovered later on that the DNA molecule was made of two chains of nucleotides and at high humidity i.e when exposed to water it becomes long and thin.
