O A. Mesozoic
O B. Palezoic
O C. Cenozoic
O D. Precambrian
Answer:
Precambrian era is the longest era in the Earth's history. It began 4600 million years ago and ended about 540 million years ago.
Explanation:
Precambrian era makes up the vast majority of Earth's history. So, the correct option is D.
What was Precambrian era?The majority of the history of the planet occurs during the Precambrian epoch. The Precambrian, which occurs before the current Phanerozoic Aeon, is the earliest period in Earth's history. The Cambrian, the earliest period of the Phanerozoic Aeon, is named after Cambria, the Latinized name for Wales, where rocks of this era were first investigated, hence the name "Precambrian."
The Precambrian period is known as the "Age of Early Life." The Precambrian period saw the formation of continents, the emergence of our current atmosphere, and the evolution and flourishing of early life. The world's oceans were home to soft-bodied animals like worms and jellyfish, while the land remained sterile.
Therefore, the correct option is D.

Which structure in the diagram below is a muscle that contracts during
inhalation?
Larynx
D
Pharynx
C
Lung
B
А
Answer:
Lung
Explanation:
Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.

This was simulation. What are some variables that this peppered moths simulation does not address?
Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.
What do you mean by Hardy-Weinberg equilibrium?The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Which feature separates watersheds?
A.) basins
B.)bays
C.)ridges
D. )rivers
Answer:
c
Explanation:
C.) Ridges are the feature that separates watersheds.
What is watershed ?A watershed is a region or area of land that collects and drains water into a particular river, stream, or other body of water.
Ridges or high points of land are critical in separating watersheds because they provide the boundary or border between two adjacent watersheds. When rain falls or snow melts, the water will flow downhill towards the closest body of water.
However, if that body of water is separated from another by a ridge, the water will flow down opposite sides of the ridge, into different watersheds.
Ridges are created by geologic processes such as tectonic uplift or erosion, and can vary in size and height. In some cases, a single ridge can divide a large drainage basin into two or more smaller ones, each with its own unique set of characteristics and ecosystems.
The boundary or border of a watershed is formed by a ridge or high point of land that separates one watershed from another. Water that falls on one side of the ridge flows into one watershed, while water that falls on the other side of the ridge flows into a different watershed.

If the food source is affecting the buffalo population, what do you predict the graph of the food source would look like? Either draw a graph or write a prediction.
Answer:
I think the number of buffalo should reduced,for the grass to grow better and act as the food for buffalo
If the food source is affecting the buffalo population, the number of buffaloes in the area should decline.
What do you mean by Population?A population may be defined as the number of individuals of the same species in a particular area at a given time.
Anything that affects the population of any species, it definitely reduces the number of specific species in a particular area. Then the affecting resource has the chance to spread in a much better way.
Therefore, if the food source is affecting the buffalo population, the number of buffaloes in the area should decline.

Example of how organisms that were previously thought of as related are actually more genetically related to organisms outside their species?
Answer:
Explanation:
Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.
But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.
Which best explains why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys
Answer:
The reason why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys securely is:
Active tectonic plate edges are found at these locations.Explanation:
Earthquakes are caused by the release of energy that occurs regularly at the edges of tectonic plates, which with their movement allow the release of said energy, which later translates into an earthquake. In simpler words, imagine that tectonic plates are pieces of a domino together next to each other trying not to leave space, each union between one piece and another is a possible focus of energy release if these pieces move, and if that happened, whatever was on them would feel an earthquake or tremor.
There are places that are much more prone to earthquakes than others, for example, San Andreas Fault, which is heard a lot by the great earthquake it could cause in California.
Answer:
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.

Joey eats strawberries for lunch. Explain how homeostasis is maintained in the endocrine systems once the fruit has entered Joey’s body.
Answer:
Explanations:
Homeostasis can be defined as the phenomenon whereby there is balance or stability within the internal and external environment of a cell or the body. The internal environment of the organism is kept constant during homeostasis. During this process there is adjustments in the
internal environment Because there is always change in the conditions inside and outside the cell. When the system of the body is able to adjust itself it's reffered to as homeostatic regulation.
The endocrine system which contains glands that is responsible for the secretion of hormones into the bloodstream play also vital part during Homeostasis, This is because hormones which are the chemical messaged effect some change cells in another part of the body. The endocrine system is responsible for the regulations of
metabolism as well as the development of some body cells and systems via feedback mechanisms, hormones such as
Thyrotropin-Releasing Hormone during Homeostasis. Therefore as Joey eats strawberries for lunch the hormones makes adjustment of muscle metabolism and also regulate fluid and ion concentration in the system or body

Some laboratory mice are spotted, due to a dominant gene. Solid color is recessive. A solid color female mouse is mated to a spotted male. Both parents are homozygous. What percentage of mice should be found in the litter?
Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Explanation: First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)
Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid
The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Hope this helps :)
