Answer and Explanation:
The cell looks like a prokaryotic cell. A prokaryotic cell might be recognized by the presence of flagellates used to move (the four long filaments located posterior to the cell). There are also many pili surrounding the cell wall (the small little filaments). There are almost no organelles. There is a circular DNI molecule concentrated in a nucleoid (which seems to be the grey oval in the middle of the cell). Prokaryotic cells also have different compartments that depend on the type of cells, such as chlorosome, carboxysome, phycobilisome, and others (which might be the dark spiral circle in the anterior part of the cell). Two differences with the cell of an onion peel are that the onion peel cell has its genetic material surrounded and protected by the nucleus membrane, whereas the prokaryotic cell lacks a delimitated nucleus. Also, the onion peel cell has a hexagonal shape and lacks flagellates and pili, unlike the prokaryotic cell, which uses the to move. The onion peel is a multicellular structure, while the prokaryote is a one-celled organism. There should always be a cover glass over the cell or tissue we are looking at. Fasten the slide with the stage clips. Move the lens carefully in order not to damage it or the slide. Do not touch or clean the lens with the fingers and try not to stain them.why are fossil fuels considered finite?
Answer:
A finite resource is something that can only be consumed once without possibility of being recycled for re-use. Because fossil fuels are burned, they cannot be reused and are therefore a finite resource.

How might global climate change effect iguana populations?
Answer:
Since iguanas are cold blooded animals and can not regulate their own body temperatures, once temperatures reach 40° they become immobilized and they cant move, so if it is cold they will die.

Answer:
1. It's difficult to find out if someone is blood doping because the body has red blood cells. First the doctors get blood samples. Because the body constantly produces new blood, the blood that was stored shows that it is old with the blood samples it shows that there are some new and some old blood cells, which is how you can tell if they are doping.
2. Hemoglobin is a protein that is produced by the body that carries oxygen in the red blood cells the more red blood cells the more hemoglobin you have. Ex; If the athletes have a high level of hemoglobin on the day of the race than it had been days or weeks before, to shows that the athlete was blood doping.
3. It can help the body produce more blood cells to carry more oxygen (get more energy) and the body can get used to that kind of high altitudes and climates. Which leads to you getting even more energy at lower altitude levels.

Explain how asexual reproduction works. what organisms undergo asexual reproduction?
Answer:

Scientists can identify the gene mutated in a bacterial auxotroph by transforming the cells with a genomic library in which fragments of the auxotroph's genome have been cloned into plasmids.
a. True
b. False
Answer: false
Explanation: this can only be true if the genes in the genomic library fragments have been identified and if the mutation is an SNP and not an inversion or deletion or insertion, whether they were cloned into plasmids or not.

State a technology and
explain how it is used to
forecast a future event.
I don't really know your question but I will tell you what can be predicted.
But how can a technological forecast be made to contain probability dimensions in the same way other forecasts do? Most people think of a technology as a quite specific physical entity. They do not conceive of this entity as having the variable characteristics which would permit range forecasts or probability statements. To their minds, a precisely defined technology either will exist in a given situation, or it will not. And the forecaster must predict this exact event or else he is wrong. This misconception—which would place an impossible demand on any forecaster causes much of the confusion in discussions about technological forecasting.

pls hurry In which parts of the cell cycle would chromosomes be paired up? Check all that apply. interphase metaphase I anaphase II telophase II metaphase II telophase I
Answer:
metaphase I
Explanation:
The cell cycle encompasses the series of processes that divides a cell into daughter cells. The cell cycle is made of mitosis and meiosis, which are the types of cell divisions. Meiosis occurs in two division steps namely: meiosis I and meiosis II.
The stages in these meiotic process are prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. Note that, meiosis I involves homologous chromosomes while meiosis II involves sister chromatids. According to this question, Chromosomes pair up in the PROPHASE I stage and remains paired in the metaphase I stage until the separate in the Anaphase stage. Hence, chromosomes will be paired up in the METAPHASE I stage.

from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.
Which of the following is a renewable source of energy?
O A. Solar energy
O B. Nuclear power
C. Coal
D. Natural gas
Answer: A. Solar energy
Explanation:
Hope this helps :)
Solar energy is the renewable source of energy. So, the correct option is A.
What is Renewable resources?A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, furthermore known as a flow resource. This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
Renewable energy is generated by renewable resources that replace themselves more quickly than they are used up. Examples of these sources that are continuously replenished are the sun and the wind.
Solar energy, wind, falling water, geothermal heat from the soil, biomass from plants, waves, ocean currents, temperature variations in the oceans, and tide energy are all examples of renewable resources.
Therefore, the correct option is A.

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.

Use the ideas of natural selection to suggest how woolly mammoths may have developed..
Science !!
PICTURE BELOW
Answer:
thats crazyyyy
Explanation:
Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.
The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.
The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.
For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.
