Describe the importance of Tiktaalik roseae to the study of evolution.
Answer:The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.
Explanation:can i have brainless?
Tiktaalik roseae was famous for his discovery of well-preserved pelves and a partial pelvic fin in aquatic organisms. These structures support aquatic organisms to a large extent.
What is Evolution?Evolution may be defined as a methodology through which gradual changes in organisms may take place over many generations. Due to this, a species of animals, plants, or insects slowly change some of their physical characteristics and adapt to nature.
According to the context of this question, it was the time of about 3.75 million years ago, when the transition between fish and first-legged animals was observed. This observation clearly demonstrates that the evolution of hind legs in the animals was actually initiated through the hind fins of the fish.
Therefore, the importance of Tiktaalik roseae to the study of evolution is understood by the fact of describing well-preserved pelves and a partial pelvic fin in aquatic organisms.

how would you check that the destarching had been effective
Answer:
Test a leaf or two for the presence of starch in order to determine whether the plant is completely destarched. If a positive result is obtained - leaves turn blue-black, the plant should be left under in the cupboard or under the coverd bell jar for longer, until a negative result- no colour change - is obtained.

The diagram below represents some changes that took place in a bacterial population recently exposed to an antibiotic.Which statement would best explain the presence of bacteria on day 4?A) A bacterial population cannot survive exposure to antibiotics.B) This bacterial population cannot survive exposure to this antibiotic.C) Bacteria can change whenever it is necessary to survive antibiotic treatment.D) Some of the bacterial population was resistant to this antibiotic.
About the question:
You will find the diagram used to answer the question in the attached files.
Answer:
D) Some of the bacterial population was resistant to this antibiotic.
Explanation:
The term resistance refers to an inheritable change in a population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach a desired effect on the target population.
The excessive use of antibiotics on the bacteria population leads to the fixation of new mutated genes -by natural selection-. The mutated genes make these cells even more resistant to the drug.
In the exposed example we have,
Day 1 ⇒ a big population of white bacteria and only one black cell, probably carrying mutated genetic material.The population was treated with antibiotics.
Day 2 ⇒ there are fewer white bacteria and three black cells. This means that white bacteria are dying, while the black ones are reproducing.The mutated phenotype gets to survive under the effects of the chemical.
Day 3 ⇒ There are no more white bacteria. Only the black population survived and keeps reproducing.The mutated bacteria reproduce with the capability of tolerating the antibiotic dose that is usually used to destroy a population of white bacteria.
Day 4 ⇒ Black bacteria got to survive a produce a big population. Remember that bacteria follow the exponential growth model, meaning that their reproductive rate is too high. This black population survived the antibiotic action and reproduced at high rates.What is the name given to your gag reflux organ?
Answer: pharyngeal reflex
Explanation:
The gag reflex, also known as the pharyngeal reflex, is when your pharynx contracts and your larynx pushes up, contracting your throat.
The afferent limb of the reflex is supplied by the glossopharyngeal nerve (cranial nerve IX), which inputs to the nucleus solitarius and the spinal trigeminal nucleus. The efferent limb is supplied by the vagus nerve (cranial nerve X) from the nucleus ambiguus.

When a scientist uses radiometric dating to determine the age of a rock specimen, would he use a radioactive element with a short half life, say a half-life of less than 10,000 years, or a radioactive element with a long half-life, say a half-life greater than 1 billion years?
Answer:
He will use a radioactive element with a long half life of greater than 1 billion years
Explanation:
Rocks are an aggregation of solid mass which is usually rich in minerals. The age of rocks is established using radiometric dating method.
According to Oxford Dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."
The age of rocks can only be ascertained using isotopes that have very long half lives because many of these rocks are very old (aged billions of years) hence their age can only be determined using elements that has a half life greater than 1 billion years.

1Which waste needs to be sorted and which can be disposed of in the general bin? 2How do you know which wastes can be recycled and sorted? 3Provide arguments to show that we save energy by making items from recycled materials.
Answer:
Waste which needs to be sorted are: Plastic, paper, and alminium. And the ones can be disposed can be any other items such as food, sweet wrappers, plastic wrapping, and broken glass.
The waste bags are opened and the waste is put onto a conveyor belt and moved into a processing area. First, the waste will go into a pre-sort area, where any items that can't be recycled are removed, and then the materials move into an area where they can be sorted automatically by machines, or manually by workers.
As most people know, recycling can reduce pollution, animal harm, and energy because we won't need as much material to be making the same thing over and over again so in general, recycling is the best way to save energy and for the sake of the planets environment.

A chemist wants to show how the molecular structures of the major greenhouse-effect contributors allow them to
absorb heat.
Which of the following would the chemist not be modeling?
A) carbon dioxide
B) carbon monoxide
C) chlorofluorocarbons
D) nitrous oxide
E) methane gas
Answer:
Option C is the correct choice
Explanation:
The major contributor of green house effect are
a) Carbon dioxide (CO2)
b) Carbon Mono-oxide (CO)
c) Nitrous oxide
d) Methane
e) Ozone
The chlorofluorocarbons (CFCs) is a man made green house gas and hence the chemist will not model it as it does not allow to absorb heat. Instead it leads to non ending chain reactions with the ozone layer thereby degrading it and hence allow entry of harmful UV rays.
Option C is the correct choice

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
