What happens during mitosis in normal cells grown in tissue culture?Cell division, or mitosis (meiosis in germ cells), is a process that involves a number of dynamic processes and the coordinated interactions of numerous cellular parts. The DNA that has been copied condenses into chromosomes during mitosis and is then joined to what is known as the "mitotic spindle," a complicated structure.
How do your cells multiply when you suffer a paper cut?The explanation is that new cells are created during mitosis whenever we suffer an injury. A parent cell divides into two daughter cells with an equal number of chromosomes during the mitotic phase.

When in a complex with ________, the cap protein binds to the cap site and ________ the expression of the lac operon.
Answers
There is a binding site for a protein called the protein degradation activator protein proximal of the transcription (CAP).
The binding of something like the CAP protein bending the DNA as well as facilitates RNA polymerase attachment, which dramatically improves the transcription of both the lac operon.With the help of coupled CAP, RNA polymerase may connect to the lac operon promoter. Whenever lactose has been available, the operator would activate the lac repressor This makes it possible for RNA polymerase to continue transcription of something like the operon on the DNA. Catabolite activator protein (CAP) should indeed connect to cAMP for RNA polymerase to start transcription of either the lac operon.The DNA located 61.5 kb forward of the transcription start point is where the protein degradation gene activator-cyclic AMP combination (CAP) interacts and positively controls the lactose (lac) operon promoter.

In this illustration, the small blue spheres represent water molecules. Sections A and B are divided by a membrane, with section A containing fewer water molecules than section B. In which direction will water molecules move across the membrane? Sections A and B are divided by a membrane, with section A containing fewer water molecules than section B Question 9 options: Water will move from A to B There will be no net movement of water. Water will move from B to A.
Answers
Through an osmotic process, water can freely go from a more diluted solution to a less diluted one. It follows its concentration gradient and does not need energy. Option 3 (or C) Water will move from B to A.
What is osmosis?
Osmosis is a simple passive transport process through which water molecules move from one side to the other of the membrane.
Water follows its concentration gradient, so it does not need energy to be transported. Water moves from the most diluted side to the more concentrated one.
When dilutions have different concentrations, there is a difference in the number of water molecules moving from one side to the other.
Solutions reach a dinamic equilibrium when concentrations at each side of the membrane are the same.
In the exposed example, sections A and B are separated by a semi-permeable membrane, and A contains fewer water molecules than B.
Water will move from A to B ⇒ NOThere will be no net movement of water ⇒ NOWater will move from B to A ⇒ YES
Water moves from B to A because in section B there is a greater concentration of water than in A. So water follows its concentration gradient and moves forward to A.
Option 3 is correct.

Because purple is dominant to white in this situation, all the offspring will be purple since every offspring produced from this cross will be a heterozygote (Pp). Consequently, there is no chance that a child will produce flowers that are white.
How many flowers will result from crossing a homozygous dominant purple flower with a heterozygous purple flower?Homozygous dominant purple flowers make up 25% of the F2 generation, while heterozygous purple flowers make up 50% of the F2 generation (homozygous recessive, white flowers).

Write an essay about why or why not: Should scientis clone the DNS of dinosaurs and bring them back to populate the earth?
Answers
DNA degrades over time. Dinosaurs went extinct about 66 million years ago, and so much time has passed that it is highly unlikely that any dinosaur DNA remains today. Dinosaur bones can survive millions of years, but dinosaur DNA almost certainly cannot.
The oldest DNA fragments found are only 800,000 years old, so cloning dinosaurs is probably impossible. True cloning also requires intact living cells and has been successful only in host animals of the same species. This also excludes mammoth clones. If you dig up a fossil today the dinosaur DNA in it would have fallen apart long ago.
So, as far as scientists know even with the best technology available today, it's impossible to make a dinosaur out of DNA. Scientists are now working to reverse extinction by bringing animals that disappeared from the earth long ago back into our lives. By manipulating the genetic code of a closely related species' DNA we can slowly build and manipulate a model of the species' DNA in reverse.

• D. An increase in bubbles on the plant when it is moved under a brighter light

Answers
An increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles are [tex]O_2[/tex].
PhotosynthesisDuring photosynthesis, green plants use their chlorophyll to absorb sunlight. This solar energy is then used to fix carbon dioxide and water into glucose while oxygen is liberated as a by-product of the reaction.
The process happens through a series of steps. Some happen in the presence of light while others happen without light. Those steps that require sunlight are said to be light-dependent while those that do not are said to be light-independent.
The overall equation of the reaction is written as follows:
[tex]6CO_2 + 6H_2O -- > C_6H_1_2O_6 + 6O_2[/tex]
Since the reaction depends on light, the brighter the light, the faster the rate of the reaction, all other factors being equal. The faster the rate of the reaction, the more bubbles of oxygen will be formed.
In other words, an increase in bubbles on the plant when it is moved under a brighter light would give indirect evidence to support the hypothesis that the bubbles on the water plant are oxygen gas.
