Answer:
Explanation:
Cancer is condition in which cells grow without control and rapidly divide. The discovery of paclitaxel's mechanism of action would be exciting because it may stop the division of abnormal cells. ... Cancer patients could not be given chemotherapeutic drugs indefinitely.
Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.
Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.
Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.
Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.
Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.
Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.
Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.
Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.
Answer: The correct answer to the question is option D
CAST FOSSILS.
Explanation: To understand what a cast fossil really is,let's look at what a fossil is generally.
Fossils are traces of what are formed and left of living things which dates back to a long time ago. Fossils are often found in sedimentary rocks examples; Shales, limestone and sandstone.Fossils are left over animals/plants.
Not all fossils are remains of living things.
There are different types of fossils; FROZEN FOSSILS; When an animal is trapped and freezed as a result of drop in temperature.
IMPRINT FOSSILS; They are prints made and left when animals walk or move over clays,these imprints dries and get covered by other sediments.plants also leave imprint fossils.
AMBER FOSSILS; These are fossils that are formed when tiny insects and bugs become trapped in saps of trees, when these saps dries up,they become hard and and an Amber is formed.(a seminiferous material).
CAST FOSSILS; These are fossils that form as a result of the death of plant,animal or any organism,when this happens,chemical reaction occurs which brings about a degradation in the bones and flesh if the organism,cavities are formed and minerals are deposited in those cavities bringing about a cast which looks like the original form or image of the organism.
Ummmm... from my book females have wider area 90 degrees or something like that, while males have slimmer area like 60 degrees or something. Obviously not everyone has that type of area surface but I think ?typically? They are around those degrees.
Well, hope this helps you even though it is all weird and stuff
Answer:
5: The phenotype for both parents is being tall.
6: 25%
7: 50%
8: 25%
Explanation:
5: We are shown that tall plants are dominant over short plants, and the genotypes of both parents are Tt (tall, short). This means that both parents will be tall.
6: The Punnet Square shows us that 1 out of 4 offspring are TT, 1/4 is 25%
7: The Punnet Square shows us that 2 out of 4 offspring are Tt, 2/4 is 50%
8: The Punnet Square shows us that 1 out of 4 offspring are tt, 1/4 is 25%
