In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
Explanation:
Answer:
Explanation:
Prophase- During this phase the genetic material inside the nucleus condenses an the duplicated chromosomes become visible. Outside the nucleus, a spindle starts to form.
Metaphase- During this phase the centromeres of the duplicated chromosomes line up across the center of the cell. Spindle fibers connect the centromere of each chromosome to the two poles of the spindle.
Anaphase- During this phase the chromosomes separate and move along spindle fibers to opposite ends if the cell.
Telophase- During this phase the chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin.
Where are the tectonic plates located?
Answer:
The outermost part of Earth's structure is known as the lithosphere. The lithosphere consists of the crust and small portion of the upper mantle. The lithosphere is divided into a number of tectonic plates. These plates move and interact with one another, driven by convectional forces within the Earth.

An mRNA strand is 108 nucleotides long. The maximum number
of amino acids that could form in the resultant polypeptide chain is
Answer:
36 amino acids
Explanation:
A messenger RNA (mRNA) is a type of RNA formed during transcription of DNA. mRNA contains nucleotide bases that are read in a group of three i.e. triplet called CODON. Each codon specifies a particular amino acid when translated.
Hence, in an mRNA strand that is 108 nucleotides long. This mRNA sequence will be read in three's with each three nucleotide corresponding to one amino acid. Hence, to get the maximum number of amino acids that could form in the resultant polypeptide chain, we divide as follows:
108 bases ÷ 3 bases (codon)
= 36 amino acids

What holds amino acid chains within a protein in shape?
Answer:
Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they serve as the catalysts for virtually every biochemical reaction that occurs in living things. This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures.
In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by different bonds and folded into a variety of three-dimensional structures. The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein.

Why does dna need to replication short answer please
DNA replication needs to occur because existing cells divide to produce new cells.Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.
The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.
( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)

Explain how an imbalanced ecosystem be beneficial
Answer:
Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as their environment. ... Therefore, this balance is very important because it ensures survival, existence and stability of the environment
Explanation:
If one species is lost the entire ecosystem can stop working. ... If something happens in an ecosystem, it can shift from a state of balance to a state of imbalance. Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem.

How did photosynthesis and cellular respiration affect Earth's atmosphere?
Answer: it is line A the other person is wrong.
Explanation:
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
hope this helps
While cellular respiration emits carbon dioxide into the environment, photosynthesis absorbs carbon dioxide.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that decompose glucose to generate Energy, which is then utilized as fuel to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
The goal of cellular respiration is straightforward: it provides cells with the energy they require to function.
The greater the rate of photosynthesis relative to respiration, the faster ecosystems 'take in' atmospheric carbon.
As CO2 levels in the atmosphere rise due to human activity, causing global warming, the balance between photosynthesis and respiration in individual plants can shift.
Thus, this way, photosynthesis and cellular respiration affect Earth's atmosphere.

Summarize in 2-3 sentences the process of photosynthesis
Answer:
Photosynthesis is a chemical reaction where plants take in carbon dioxide (CO2) and water (H2O) through its stomata. With the help of sunlight and chlorophyll, which is found in its chloroplast, it is used to produce glucose (C6H12O6) and oxygen (O2). It converts light energy (sunlight) to chemical energy.
Explanation:
Answer:
please mark me brainlest!!
Explanation:
photosynthesis, plants take in carbon dioxide and water from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and conversion of CO2 into carbohydrates (carbon fixation).

Suppose the great, green galoofus lizard has 28 chromosomes in the nucleus of its unfertilized eggs. Predict how many chromosomes will be in the skin cells of a great, green galoofus lizard?
Answer: 56
Explanation:
Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes).
