Option C
Bones
Explanation:
Trace fossils (or ichnofossils) are geological records of biological activity. They are fossils, but not of the living things themselves.
Trace fossils may be impressions made on the substrate by an organism. Burrows, borings, footprints, bones, feeding marks, and root cavities are examples.

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
Answers
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 would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answers
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells

What are the different parts of a bacteriophage? Where is the DNA stored in this virus?
Answers
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.

Look at the food web. In your response, answer the following questions
correctly for full credit: a) Identify the producers, primary consumers, and
secondary consumers in the ecosystem. b) What would happen if all the
hawks in this ecosystem were to die from an illness? c) Why would you
expect there to be fewer foxes than caterpillars in this ecosystem? d)
Which organism would have the smallest population? (8 points)
Answers
Answer:
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers.
B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash.
C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population.
D) The hawk has to be the smallest population.

Explanation:
According to Mendelian's law of inheritance, the dominant allele is the allele that is expressed in an individual while the recessive allele are usually not expressed in the phenotype of an individual.
If a parents is dominant for a particular allele of tallness and recessive for a particular allele of shortness it is observed that the dominant allele is what is expressed in the phenotype of the offspring and inherited in simple Mendelian fashion by the offspring.
A scientist could best determine which ion (F-, Cl-, Br-, or I-) produced the greatest electrical potential in the Experiment by comparing the electrical potential that develops between ice and:
a solution of each sodium salt at the same concentration.
a single sodium salt solution at different concentrations.
a single sodium salt solution at different temperatures.
droplets of sodium salt solutions at different collision rates.
Answers
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

An elderly neighbor says today's girls are less mature than they used to be. He says it used to be that by the time a girl had a mature body, she had
a mature brain to go along with it. The neighbor argues that it all comes down to bad parenting and too much television.
Answers
Answer:
He is trying to explain that girls in his day had more respect for their self than they do not
Explanation:
They copy what they see on tv, school,and friends
Answer:
First of all, every child develops and matures on their own pace (within a certain range) and we can't compare one person to another. Secondly, in general, girls are reaching puberty earlier than they used to, which may stem from nutritional or environmental influences. For example, in 1900, the average age of puberty for girls was fifteen; today, it is twelve and a half. Moreover, attaining puberty or having a mature body doesn't result in a mature or fully developed brain. The brain continues to develops on its own pace from the rest of the body, until into adulthood to the age of twenty-five.
