Answer:
The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.
Explanation:
Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.
Answer:
The muscular system is the set of more than 650 muscles in the body, whose main function is to generate movement, whether voluntary or involuntary.
Explanation:
The functioning of the muscular system can be divided into 3 processes, one voluntary in charge of the skeletal muscles, the other involuntary carried out by the visceral muscles and the last process is the duty of the cardiac muscles and autonomous functioning.
Skeletal muscles allow walking, running, jumping, in short, they empower a multitude of voluntary activities. Except for reflexes, which are the involuntary responses generated as a result of a stimulus. As for involuntary functioning muscles, it can be specified that they perform independently of our will but are supervised and controlled by the nervous system, they are responsible for generating pressure for the transfer of fluids and the transport of substances throughout the organism with the help of peristaltic movements (such as food, during the digestion and excretion process).
The autonomous process takes place in the heart, an organ made of heart muscles. The primary function of this muscle tissue is to contract regularly, millions of times, having to endure fatigue and weariness, or else the heart would stop.
Answer: A, B, C
Explanation: I got the answer from USA test prep
It is approximately 1.7% of humans that are found to be born with biological traits that are associated with neither exactly male nor female. These conditions are called intersex, meaning that a person is born with reproductive system/s or organ/s that neither fits the characteristics of females or males.
I'd say Solar energy is a source we humans could use in the future
