Answer:
Type I.
Explanation:
The statistical hypothesis can be used in the scientific experiments to explain any observation or the results. Two main types of hypothesis are null hypothesis or alternate hypothesis.
Sometime error might also be done by the individual while accepting any hypothesis. In Type I error, the individual rejects the correct hypothesis and accept the alternate hypothesis which is wrong. Dr. Mai has also done Type I error in her experiment.
Thus, the answer is Type I.
Answer and explanation;
-All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. Fats are triglycerides.
-The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.
-Lipids are water-insoluble (hydrophobic), and this property is put to great use in the organisation of cells and tissues.
For example; phospholipids are a class of lipids that is amphipathic; that is it contains fatty acid tails that are hydrophobic, and a phosphate head that is hydrophilic. This means the phosphate group will orientate itself towards water and away from the rest of the molecule, and also gives rise to the special properties that allow phospholipids to be used to form membranes.
Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
Asexual reproduction the the act of an organism producing offspring by themselves, without the assistance of another organism. Asexual reproduction has many different advantages, but the primary one would be that reproduction can occur with a single parent as opposed to two.
