Answer:
Q1 As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts.
Q2When stars first begin to fuse hydrogen to helium, they lie on the zero-age main sequence. ... The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.
What would happen if the muscles that control structures in the larynx became paralyzed?
Answer:
It depends.
Explanation:
Considering that the Larynx is responsible for creating an air passage, and allowing us to speak; if those muscles become paralyzed, then you would not be able to speak and have a very hard time breathing (or you would stop breathing).
what are types of scientific explanation
Answer:
theories, models, and laws
Explanation:
Carbohydrates can be used for energy storage or to build structures. Plants store energy as ________A__________ and animals store energy as _______B_________. Plants build structures out of ______C__________.
Answer:
A. starch
B. glycogen
C. cellulose
Explanation:
Molecules of carbohydrates providing energy and support consist primarily of sugar polymers. They are formed from monosaccharide monomers in long chains and rings. The basic composition of monosaccharides, disaccharides and polysaccharides comprises the elements C, H O, with several polar groups of OH.
Polysaccharides consist of glucose joined by 1-4 glycosidic bonds. They are used as energy storage in photosynthesis and used by animals in respiration, ethyl alcohol fermentation and lactic acid fermentation for ATP synthesis. Plants transport glucose as sucrose, and store it as starch, while animals store glucose as glycogen.
Glucose is readily converted into another form of chemical energy as ATP. Plants also make up insoluble and stable cellulose and lignin structural units in plants.
1.How would you describe the relationship between the eagle and the hare?
2.According to the video, why can't the eagle afford any mistakes?
3.How could an overpopulation of eagles affect the hare population?
1)Describe the relationship between a predator population and the population of its prey.
2)What is a keystone species? Give an example.
3)What is a limiting factor? Give an example.
4)What is the role of camouflage in prey and predator?
Explanation:
1. Remember, the video began with the words, "For one death, for the other, are all decided in an instance." Meaning, both could result in each other harm. There is
2. The eagle can't afford to make any mistakes because we are told, "even the slightest injury can leave it too weak to hunt and cause it to stave."
3. More eagles means more hares are hunted, and as more hares are been killed, the lesser the hare population.
4. The increase in the predator population leads to a reduction in the population of the prey. In other words, as more predators start looking for prey to eat, the prey population decreases.
5. In simple words, a keystone species is a type of predator whose presence in the community has far-reaching effects on other species in the community. One common example is the sea star species found in coral reefs, see stars feed on mussel and sea urchin thereby helping to regulate the population of mussels and sea urchin. Doing this ultimately helps other species survive.
6. A limiting factor is an attribute or factor that reduces the exponential growth in the population of an organism.
7. Camouflage allows preys to hid from their predators. Usually made possible by their physical appearance.

How are primary and secondary succession similar and how are they different?
Answer:
Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.
Answer:
Both human and natural activities that result in a substantial change in the composition of an area create primary and secondary succession. In locations where there is no soil, primary succession takes place, and in areas where there is soil, secondary succession takes place.

What are codons and anticodons?
Answer:
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence. An anticodon is found at one end of a transfer RNA (tRNA) moleculeExplanation:

explain the difference between an
autotroph and an heterotroph.
Answer:
The answer will be listed below.
Explanation:
Autotroph and heterotroph are two different terms. Autotrophs are producers, such as plants and other organisms that can produce their own food. Heterotrophs are consumers who consumes producers or other consumers to get their food. Examples include animals, people, and those who consume other things for energy.

write down at least 5 examples of dominant, recessive or co dominant alleles and what their crosses would yield
Answer:
If both alleles are dominant, it is called codominance. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant Dominant and Recessive Traits List 1． Widow’s Peak. Also known as mid-digital, hairline is a result of expression of the hairline gene. The gene contains 2 alleles: one for straight hairline, which is recessive and the other for widow’s peak, which is dominant.
