Answer: There are 3 answers.
1- Plate tectonics causes loss or displacement of fossils.
2- Most organisms never fossilize, leaving holes in the fossil record
3- Because marine fossils are prevalent, this can lead people to believe they were more dominant than they actually were.

What type of signals does the nervous system send? What carries these signals?
What are the main organs of the nervous system?
Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

What are the different parts of a bacteriophage? Where is the DNA stored in this virus?
Answer:
What are the differents parts of a bacteriophage?
The tailed phages have three major components: a capsid where the genome is packed, a tail that serves as a pipe during infection to secure transfer of genome into host cell and a special adhesive system (adsorption apparatus) at the very end of the tail that will recognise the host cell and penetrate its wall.
Where is the DNA stored in this virus?
Where is DNA stored in viruses?
The genome of most DNA-containing viruses that infect eukaryotic cells is transported (with some associated proteins) into the cell nucleus, where the cellular DNA is, of course, also found.

Imagine customers moving into and out of a coffee shop. Which situation
resembles how a reaction in dynamic equilibrium acts?
A. There are the same number of people inside the coffee shop as
outside it.
B. People enter the coffee shop at the same rate as others leave.
C. No people are moving either into or out of the coffee shop.
D. Some people sit down and drink their coffee slowly, while others
drink theirs quickly while standing up.
No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.
Option A, C, D are not a good analogy for dynamic equilibrium.

What two things below most affect the amount of dissolved oxygen in water?
Answer:
Dissolved oxygen levels will fluctuate with temperature
Explanation:
While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³. As such, dissolved oxygen levels can range from less than 1 mg/L to more than 20 mg/L depending on how all of these factors interact.

1. The colour of a tomato can be represented by RR, Rr or rr. Why do we use capital
letters for some symbols and lower case letters for others? Why are there two
symbols for one trait (characteristic)?
Answer:
The capital letter is used to show a dominant trait, while a lowercase is used to represent a recessive trait.
Explanation:
If you are to take a Mother and a Father as example, and they have 3 children, the father's brown eyes as example we can show the children with capital and lower case depending on their looks. If the Father had brown eyes and 2 of his children out of 3 have brown eyes, we can represent that as a dominant trait, so it would be R. Then, if we take the father's hair color, brown, and the mothers hair color, blonde, we can say 2 of 3 children have brown hair, so 1 of 3 children have brown hair. So we now know that brown hair is a recessive trait. 2 of 3 children have blonde hair so the child with brown eyes and blonde hair could be represented like "Rr". Hope that helps, this is just my little explanation of this!

Fossils of tropical plants have been found in the Earth's polar regions. How could this be explained?
A. The continent on which the tropical plants lived changed latitudes over time.
B. The fossils are of arctic species that look like tropical species.
C. Seeds from tropical plants were carried to the polar regions by birds a long time ago.
D. Tropical plants were able to withstand much colder temperatures in the past.
Answer:
A.The continent on which the tropical plants lived changed latitudes over time.
Explanation:
When the Fossils of tropical plants should have found so this explained that the continent where the tropical plants lived changed latitudes over the time. hence, the option A is correct.
Where are the Fossils of tropical plants found?Mainly it should be found in the Svalbard which is situated in the Arctic Ocean. But at the same time it should be found in the Earth's polar regions.
And, it explained the continent where the tropical plants should be lived also it changed the latitudes over time.

In the field of medicine, researchers have recently designed a technique that allows them to use adult
stem cells to test the potency and safety of newly designed drugs for humans. What is the most
likely advantage of this new technology compared with other forms of drug trials?
A
It helps ensure that the shelf life of newly designed drugs is as long as possible.
B
It helps ensure that the newly designed drugs can cure all patients they are used to treat.
C
It helps reduce the demand to test newly designed drugs on animals.
D
It helps reduce the time it takes to bring newly designed drugs to the market.
Answer:
The answer is B
Explanation:
The technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.
The stem cells to test newly designed drugs for humansUse important stem cells to define the toxicity of new drugs presented results in preliminary tests. The rational use and search for alternative methods to the use of animals in scientific research is currently a worldwide concern. However, despite the stages of the scientific community, it is still not possible to open animal experimentation in the so-called pre-clinical development of new drugs and other products for human health.
With this information, we can conclude that the technique that allows them to use stem cells to test the potency and safety of newly designed drugs for humans, helps reduce the time needed to bring newly designed drugs to market.

Which of these activities would be least likely to help scientists explain the origin of life on Earth? determining how pollution is affecting life in the ocean
determining how the atmosphere became rich in oxygen
determining how cells could develop from nonliving matter
determining how organelles developed from symbiotic organisms
Answer:
B
Explanation:
Determining how the population affects life in the ocean is the least likely to help scientists explain the origin of life on Earth. Therefore, option A is correct.
What is the origin of life?The origin of life means the emergence of organisms on earth. Many scientists tried to explain how life originated on the earth and gave various theories, like panspermia, common descent, gradualism, natural selection, etc.
The first organism that originated on the earth was microbes in water. When the earth formed, it was reduced in nature. Gradually oxygen formed on the earth which was very helpful in the origin of life. Some theories explained how cells could develop from nonliving matter.
determining how the population is affecting life in the ocean is not related to the origin of life. Hence, option A is correct.
