Answer:
The correct answer will be-
1. Observation-option B.
2. Hypothesis-option A.
3. Experiments- option C.
Explanation:
A scientific method involves various steps to explain a natural phenomenon of nature. It begins with making an observation which leads to asking the scientific question. The researcher does background research and proposes a hypothesis which could be tested through experiments. The experiments could prove or disprove the hypothesis based on the results.
In the given question the observation made is an equal amount of A and T and G and C are observed. It leads to a hypothesis which shows that this could have happened due to the winding of two strands of DNA and the experiments was performed through X-ray diffraction pattern.
Thus, the selected options are the correct answer.
Answer:
Photosynthesis
Explanation:
The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.
Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.
A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.

Answer:
Dermis
Explanation:
The hair follicles are present in the dermal papillae of the dermis layer. The dermal papillae are a series of triangular-shaped cells. The hair follicles are extending from the skin surface to the dermis layer of the skin. The hairs are the extension of the epidermis layer into the dermis layer of the muscle. The hair follicle has 2 parts, such as - the part which extends outside of the epidermis known as the shaft. The base of the follicle known as root. The hair follicle itself has different parts - outer root sheath, inner root sheath, and a centrally placed hair shaft. The erector muscles help in goosebumps of hair during cold.
