Answers
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

Answers
Answer:C each species was unchanged since the moment of its creation
Explanation:
people believed we were all the same and we just were there on the earth
Before Darwin's theory of evolution people believed that : ( C ) Each species was unchanged since the moment of its creation
Before Darwin proposed the theory of evolution most people believed that the species of plants and animals on earth were not connected to each other and could not have evolved from each other. because they believed that human species were outside the earth given that the earth was perceived as been too young.
Darwin's theory of evolution proposes that species evolve ( change in physical attributes ) over time through the process of natural selection. Darwin believed that man evolved from Apes over million of years.
Hence we can conclude that Before Darwin's theory of evolution people believed that : Each species was unchanged since the moment of its creation.

Accoring to the data table, Molly observed rust on the sample of iron filing and dries the sample thoroughly. She then finds the mass of the entire sample and finds it has more mass than the 188g of the original sample. As the rusted iron filing occurred in an open system, which of the following best explains the increase in mass?
Select one:
A. The sample gained mass because rust is a different color than the iron fillings, and the different color rust has more mass that the original iron fillings.
B. The sample gained mass because the iron fillings combined with oxygen in a chemical reaction, thus making the final rusted sample to have more mass.
C. Molly made a procedure mistake when measuring the mass of the entire sample. She should remeausre her sample.
D. The sample gained mass because rust is a physical change and the color change causes the mass to be more than the original sample.

PLS DONT COPY AND PASTE THE ANSWER FROM THE INTERNET
Answers
The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.
How Oxygen from the air is absorbed?Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart.
When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.
O2 and CO2 are constantly circulating and passing from one medium to another, so much so that O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli.
Therefore, The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body.

Which is larger, 40 centimeters or 670 millimeters?
Answers
Answer:
670 Millimeters
Explanation:
1 Millimeter = 0.1 Centimeter
670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.
What is a millimetre?It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.
It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.
The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.
Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.
Therefore, 670 mm is 67 cm which is greater than 40 cm.

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?
Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.
Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.
The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.
The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.
Answers
Answer:
breeding with and altering the population of wild salmon
the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects
there is a rainforest in BC that's survival relies on the nutrients that salmon bring when they spawn and die
It could also be scare mongering and have no negative effect, could be a net positive??

Maybe they should experiment a little more, because they are not completely sure about them yet, and it could cause seriously disastrous consequences, like brain damage, but vaccinations are good. They will help people to not get sick, and hopefully lower the spread of disease. People are lining up to get vaccinated, because they are afraid of the disease. The vaccination is a way to soothe those fears. So, the vaccination movement, is a good thing, and doctors and scientists should go ahead with it.

Answers
Answer:
The organism would be classified as a prokaryote. The reason for this, is because it's a simple organism that lacks a nucleus, and is unicellular. (hope that helps)
You would have to classify this organism in the category of a prokaryote. This is because a prokaryote has a cell wall that is made up of peptidoglycan while they lack a well-defined nucleus.
What is an Organism?An organism may be defined as a type of living thing that is typically made up of one or more cells depending on its structural identity and function.
Prokaryotes are simple types of organisms that lack complex genome organization. Such types of organisms have a cell wall, flagella, etc. but do not have a well-defined nucleus and other membrane-bound cell organelles.
Prokaryotic organisms have the tendency to survive on the ocean floor where the temperature of the surrounding water is of utmost high.
