The two features would the scientist use to distinguish a plant cell from an animal cell are the presence or absence of a cell wall and chloroplasts. Thus option B is correct.
what is function of chloroplast ?Chloroplasts are the membrane bound organelle present only in photosynthetic organism like plants and algae; They are located in mesophyll cells of leaves and have a high concentration of chlorophyll pigment which absorb sunlight and absent in animal cell.
Chloroplast has extra-nuclear DNA, these are semiautonomous in nature; They synthesize food that is glucose by the process of photosynthesis by absorbing sunlight into chemical energy.
It is major house which involve in the production of NADPH and molecular oxygen (O2) released by the photolysis of water; It also produces ATP from photosynthesis.
It also indirectly participate in generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.
Thus option B is correct.

if a cell more than doubled its size before dividing what would eventually happen to the cells?
Answer:
If a cell more than doubled its size before dividing, the daughter cells would be larger than the original cell. If this happened with each generation, cells would quickly become too large to live. Similarly, if a cell did not double its size before dividing, the daughter cells would be smaller than the original cell.
Explanation:
HELP PLEASE Are animal cells and plant cells the same 4-7 sentences a claim, evidence, and reasoning PLEASE HELP.
Answer:
No, plant cells and animal cells are NOT the same. Some parts of the cells are not different such as the Chloroplasts, cell wall, ect.. Also the fact that plant cells are found only in plants and animal cells is only found in animals. Although plants and animals have some same parts, this does not make them the same.

In this energy pyramid below,which type of consumer gets only 10% of the energy stored in plants
A.herbivores
B.carnivores
C.secondary consumers
Answer: I believe it’s carnivores..
Explanation:
Every time an animal (starting with the primary consumers) eats food, they obtain ten percent of that energy. hope this helps bro
In the energy pyramid the consumer that gets only 10% is the : (A). Herbivores
Meaning of Consumers and energy pyramidA consumer is one that can not produce its own food by itself using sunlight. They do not possess chlorophyll, but they depend on the producers for food.
The energy pyramid is a pyramid that shows how energy is transferred or distributed in a food chain between the producers and the consumer. The energy in the pyramid reduces as we go up the pyramid.
In conclusion, In the energy pyramid the consumer that gets only 10% is the Herbivores

Which of the following provide evidence that natural selection occurs in peppered moths?
A. Melanic moths become more abundant than light forms in polluted areas
B. Light moths become more abundant than melanic forms when clean air legislation is implemented
Answer:
B
Explanation:
When the moths camouflage with their surroundings, they are less likely going to be eaten by their predators. So therefore, more moths are going to want to mate with the darker moths that blend with their surroundings.
Camouflage protects moths from predators. Thus, darker moths that blend in will attract more mates. Therefore, option (A) is correct.
What is natural selection?Natural selection refers to the process in which different individuals with distinct phenotypes have variable rates of survival and reproductive success. The gradual shift over time in the heritable characteristics that are typical of a population is a crucial aspect of the evolutionary process known as evolution.
It is less probable that the moths' natural enemies will consume them if they are able to blend in with their environment and use camouflage. Therefore, a greater number of moths will seek to mate with the darker moths because these moths fit in better with their environment.

In order to come to the conclusion that their hypothesis is supported, what crucial step must a scientist perform? a)Gather information and do background research. b)Make observations and record the data. c)Communicate their results and allow peers to review their findings. d) Analyze their test results to look for patterns.
Answer:
A
Explanation:
i think
Answer:
[See Below]
Explanation:
✦ In science, we usually refer to the scientific method:
✧ Question - What do you want to learn more about? What are you trying to figure out?
✧ Research - Gather your information that relates to the topic.
✧ Hypothesis - Form an "educated" guess of what will happen, what the answer will be.
✧ Experiment - Using steps, test your hypothesis.
✧ Analysis - Review all the information you collected from the experiment. As well as a written account of what happened.
✧ Conclusion - Was your hypothesis correct or not? Explain.
✦ Now for your question, if we look at the above scientific method what can we inquire that you need to PROVE that you hypothesis is correct:
✧ Gather information and do background research - This is a step but it's not crucial to PROVING the hypothesis.
✧ Make observations and record the data - This is a step but it's not crucial to PROVING the hypothesis.
✧ Communicate their results and allow peers to review their findings - This is a step but it's not crucial to PROVING the hypothesis.
✧ Analyze their test results to look for patterns - Yes! This is probably the most crucial step besides the actual test itself. When you analyze your data you can figure out if what happened in the test was what you said would happen in your hypothesis.
So It'd be D, Analyze their test results to look for patterns.

Answer:
Viruses are not living things. One reason viruses are not alive is because they require a host to survive and reproduce. A second reason a virus is not alive is because they do not stimuli. A final reason that a virus is not alive is that they are not made up of cells. All living things can reproduce without a host, are made up of cells and react to stimuli except viruses, so they are not living.

How do the positions of the aronium and antheridium relate to their reproductive function?
Answer:
Generally in non flowering plant the male sex organ is called the antheridium,while the female is called the achegonium. Due to the habitat and methods of reproduction, special adaptive feature s have been developed by these plants to ensure reproduction and prevent extinction.
Explanation:
Based on structure,Antheridial (male sex cells) are usually upright in position,with pores located at the top of the antherialdial disk.These perforation is adaptive feature for effective dispersal of sperm during reproduction.
In addition present in the archegoniu is the achegonium dsik. The latter is the adaptive feature for protection of the archegonia.The disc serve as an umbrella surface for the protection of the archegonia during reproduction.Thus ovum is well protected to ensure fertilization and prevent wastage.

Tarnishing- is a thin layer of corrosion that forms over copper, brass, aluminum, magnesium, neodymium and other similar metals as their outermost layer undergoes a chemical reaction. Tarnish does not always result from the sole effects of oxygen in the air.
endothermic -(of a reaction or process) accompanied by or requiring the absorption of heat.
