Answer:
See the answer below
Explanation:
a) Since the pink phenotype is heterozygous, the genotype would be RW.
b) The pink genotype is RW. Hence, a cross between two pink snapdragons will go thus:
RW x RW
RR RW RW WW
<u>Expected genotypes:</u> 1/4 RR, 1/2 RW, 1/4 WW
<u>Expected phenotypes:</u> 1/4 red-flowered plants, 1/2 pink-flowered plant, 1/4 white-flowered plant.
They don't offer justifications for why they are accurate. They are regarded as established facts.
- A theory essentially means the opposite. A well-supported explanation of a phenomenon in the natural world, including laws, hypotheses, and facts, is called a theory.
- A hypothesis is a statement about the natural world that can be verified by observations or tests. Hypotheses must be falsifiable—that is, they must be formulated in a fashion that allows them to be disproven—and be evaluated scientifically in order to be considered to be true.
- Scientific laws or laws of science are propositions that describe or forecast a variety of natural occurrences and are based on repeated tests or observations.
- Scientific rules condense the findings of tests or observations, typically within a specific applicability range. The accuracy of a law typically does not change when a new theory of the relevant phenomenon is developed; rather, the law's application area expands because the mathematics or statement that represents the law remains constant.
Therefore, scientific laws, theory, and hypothesis are different aspects of Science.

Answer:
it's all the way at the bottom
Explanation:
the older the fossil is the lower it is digged.
They occur when a blood vessel within the skull bursts and bleeds into and around the brain. The main cause of haemorrhagic stroke is high blood pressure, which can weaken the arteries in the brain and make them prone to split or rupture. Hope this helps :/ x
The answer can be pollination or cross-pollination.
