What happens during stage mitosis cell cycle
Answers
Answer:
Mitosis is the process in which the nucleus of a eukaryotic cell divides. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase.
Explanation:
What is the phase change from gas to liquid?
A. Sublimation
B. Condensation
C. Vaporization
D. Transpiration
Answers
Answer:
Condensation
Explanation:
Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.
Answer:
Condensation
Explanation:
Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.

Answers
Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

1.What were some characteristics that the finches developed to give them an advantage in surviving?
2.How do you think that the one species of finch evolved into many different species, each with its own advantages?
3. In what ways do these advantages help the finches to survive and reproduce?
4. What might have happened if the finches didn't evolve into many different species?
Answers
Answer:
1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.
2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection
3. Medium ground finches with larger beaks could take advantage of alternate food

A chain of reactions is initiated upon soil flooding leading to reduced (low) soil redox potential (Eh, mV) conditions. These reactions include physical, chemical and biological processes that have significant implications for wetland plants.
Physical processes include restriction of atmospheric gas diffusion in the soil leading to depletion of soil oxygen and accumulation of carbon dioxide [4,5]. ... This process leads to oxygen depletion and reduction in soil oxidation reduction potential (Eh) followed by a chain of soil chemical changes.
According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.
Answers
Answer:
99%
Explanation:
at a salt solution concentration of 2%, plasmolysis first started to occur. So the other 98% in the "solution" would have just been water. Since water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

how does the respiratory and digestive system work together to maintain homeostasis
Answers
When groups of tissues work together, they are called organs. Some
examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.
There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.
All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Your digestive system absorbs water and nutrients from the food you eat.
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses. If any system in your body isn't working properly, other systems are affected.
Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.
As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have to work together.
The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells.

You are working in a lab trying to identify a single celled organism. You are not
sure if it is a Protist or a Moneran (Eubacteria or Archaebacteria). What test
would be most useful to determine its identity?
A. Put it in the sun and measure the oxygen levels
B. Determine if it is motile
C. Test its cells for chitin
D. Determine if it has a nucleus
Answers
The test that will be most useful to determine the identity of the single-celled organism is to "determine if it has a nucleus".
DIFFERENCE BETWEEN A PROTIST AND MONERAN:
A protist is a member of the kingdom protista characterized by it's single cells and eukaryotic nature.
On the other hand, a MONERAN is a member of the kingdom MONERA and characterized by it's unicellular and prokaryotic nature.
The major difference between Monera and protista is their prokaryotic and eukaryotic cells respectively. Prokaryotic cells do not have a membrane bound nucleus while an eukaryotic cell does.
Since the major difference between Monerans and protists is their possession of a membrane bound nucleus, the identity of the single-celled organism is to "determine if it has a nucleus".

Molecules of DNA are composed of long chains of?
Answers
two long polynucleotide chains
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together
Molecules of DNA are composed of long chains of nucleotides.
What are nucleotides?Nucleotides are the building blocks of DNA and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.
The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.
Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.
A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.
Therefore the molecules of DNA are composed of long chains of nucleotides.

When the northern hemisphere points toward the sun, the southern hemisphere faces away from the sun. In this instance, it is:
A.
summer in North America, and winter in Australia.
B.
summer in North America and Australia.
C.
winter in North America, and summer in Australia.
Answers
Answer:
A
Explanation:
the northern hemisphere is the opposite from the southern hemisphere
Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.
Why are the seasons reversed in each hemisphere?The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.
Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.
