Answer:
1) Wax belong to lipids.
2) <u>Animals</u>: Water and cold isolation and protection from pathogenic microorganisms.
<u>Plants</u>: It controls evaporation and maintains hydration.
Explanation:
1) Wax belong to the biomolecules of lipids.
2) In animals, such as birds, the uropygial gland secrets sebum or wax, spreading it throughout the animal's feathers to prevent water from penetrating as it serves as an isolating compound for animals that live in cold areas. It also provides protection from bacteria and fungi. In coloquial terms, it would be like a water-proof coat that protects them from water and extreme climate.
In plants, the secretion of wax through the cuticle has been developed as an adaptation to control evaporation and maintain hydration.
Answer: The question is is incomplete, here are the options.
A.Loonand O Charles Darwin named them Geospiza leodarwini in honor of his son Leonard.
B. They come from the Darwin archipelago off the coast of Ecuador C. C. Charles Darwin collected the first scientific specimens.
D.John Gould placed them in the genus Darwinospiza
Correct option is C.
Explanation:
Charles Darwin collected the first scientific specimens.
Darwin's finches play vital role in the development of Darwin's theory of evolution and natural selection. This is because the birds called Darwin's finished have variable size and shape making them important for the development of the theory.
Theory of natural selection and evolution which was developed by Darwin states that organisms changes over time as a result in variation in it's characteristics or behavioral traits to survive , adapt and reproduce in it's environment.
1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
Answer: Survival rate up to start of April = 76.67%
Explanation: size of colony = 150mice.
Size of colony in February =125mice.
Size of colony in march = 115 mice.
1. Survivorship rate in February
= Size of colony / size in February *100.
= 122 / 150 * 100
= 83.33% to the nearest hundredth
2. Survivorship rate in march
= Size of colony / size in march *100.
= 115/150 * 100
= 76.67% to the nearest hundredth.
