B. polygenic inheritance.
C. codominance.
D. multiple allele traits.
Answer: The correct answer is- A) Incomplete dominance.
Incomplete dominance means neither of the allele ( that is dominant and recessive allele) shows its phenotype complelety. In other words, no allele is completely dominant and a heterozygous condition produces an intermediate phenotype that lies between a dominant and a recessive trait.
As per the question, the phenotype of parents are - curly hair and straight hair.
As child expresses and intermediate phenotype that is wavy hair, therefore it is an example of incomplete dominance.
The aspect of the scientific process that will decrease the likelihood of publishing low-quality research is : Statistical hypothesis testing
Statistical hypothesis testing is used to determine the conclusion from two different, conflicting hypothesis ( i.e. null and alternate hypothesis ).
This testing is carried out on a determined sample of the population and the difference between the sample and the null hypothesis determines if the results from the the statistical hypothesis testing will be accepted or not, because the null hypothesis is true. i.e.
Hence we can conclude that The aspect of the scientific process that will decrease the likelihood of publishing low-quality research is : Statistical hypothesis testing

Answer:
statistical hypothesis testing
Explanation:
The new drug must be evaluated by statistical tests in order to compare this it with a control (i.e. a placebo). This comparison must be statistically significant to accept the hypothesis that the drug is effective. The statistical significance in these tests is very important since it is the only way to accept a hypothesis with confidence that it is true. If Dr. Besson doesn't get that, their drug will hardly be released.
On the other hand, proving that the drug is safe (i.e no harmful side effects) implies more research and is more difficult to prove.

Secondary succession can happen after primary succession or independently of primary succession.
a. True
b. False
Which of the following about secondary succession is not true?
a. It occurs in ecosystems without soil.
b. It occurs in ecosystems that are already established.
c. It reduces the number of species in an ecosystem.
d. It is ...
1. Answer;
-Fungus
Explanation;
-A pioneer species is one which is the first to colonize an area, which can be seen with fungus in the way that spores are quickly spread across large areas.
-Pioneer species are usually lichens and mosses, which can grow on bare rocks. As they grow, the lichens and mosses help break up the rocks to form soil. When these organisms die, they provide nutrients that enrich the developing soil. Over time, seeds of plants land in the new soil and begin to grow.
2. Answer;
The statement above is true
Explanation;
-Secondary succession can happen after primary succession or independently of primary succession.
-Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation by forest fire, tsunami, flood, or an abandoned field.
-Secondary succession may occur independently, but the stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
3. Answer;
A. It occurs in ecosystems without soil.
Explanation;
-Secondary succession refers to the process that happens after a disruptive event, reducing the population of species in an ecosystem. As opposed to primary succession that occurs in an ecosystem lacking soil, secondary succession happens on preexisting soil.
-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
Grass is an example of a pioneer species, so option d is correct. The second statement is True. Secondary succession can happen after primary succession or independently of primary succession. Secondary succession reduces the number of species in an ecosystem thus the answer is (C).
Hardy species called pioneer species are the first to establish themselves in once-biodiverse steady-state ecosystems. Lichens, fungi, bacteria, fireweed, grasses, alder, and willow are examples of pioneer species.
In primary succession, living organisms first occupy newly exposed or newly created rock. In secondary succession, a previously inhabited area is disturbed, disrupted, and then recolonized as a result of the disturbance.
In third question, among all the given options only option (c), "it reduces the number of species in an ecosystem" is not true.
Before secondary succession starts, a variety of species will already be present in the ecosystem and new complex plants and animals move in as the ecosystem develops, bringing with them new species. so it will increase the number of species in an ecosystem.
Therefore, in question 1st, option d is right, in question 2nd, the given statement is true, and in 3rd, option c is right.
