Which of the following is true about the principle of the conversation of mass
Answer:
I don't see a file attached.
In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

The attraction that causes water and other liquids to form drops on thin
films is called______.
This is also water's ability to be attraction
to other water molecules.
A.)cohesion
B.)adhesion
C.)capillary action
D.)surface tension
Answer:
Cohesion is an attraction between substances of the same kind. Because of cohesion, water and other liquids form thin films and drops. Molecules at the surface of water are linked together by hydrogen bonds like a crowd of people linked by holding hands.
The attraction that causes water and other liquids to form drops on thin films is called cohesion.
Thus, option A is correct.
What is cohesion?
Cohesion is defined as attraction of molecules for other molecules of the same type and molecule of water have strong force of cohesion.
Cohesion is a property of same molecules of the same substance that stick to each other due to mutual attraction.The attraction that causes water and other liquids to form drops on thin films is called cohesion.
The properties of matter include a character that can be measured, such as object's color, mass, density, melting point, odor and temperature.Cohesion is defined as attraction of molecules for other molecules of the same type and molecule of water have strong force of cohesion.
Solid have high cohesive properties so they do not stick to the surface in which they come in contact.The properties of matter include a character that can be measured, such as object's color, mass, density, melting point, odor and temperature.
Therefore,the attraction that causes water and other liquids to form drops on thin films is called cohesion.

How can stem cells help a patient.
Answer:
In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.

Photosynthesis is done only by plants by using sunlight water and CO2
All living organisms can do cellular repirations
She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.
Aerobic Respiration
Anaerobic Repiration
If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration
If it does not contain sugar it goes to Anaerobic Respiration
Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall
2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36
Anerobic: They fall part to 2 major respirations of this section which are
1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol
2.Lactic Acid - gain 2 ATp and no oxygen and used in yogurt you eat and it creates sore in your muscles
She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them
Hope that answers the question
How many molecules of atp are needed for each "turn" of the calvin cycle
Answer:
3 ATP
Explanation:
Each turn of the Calvin cycle also uses up 3 ATP and 2 NADPH in the processes of reducing (adding electrons to) 3-phosphoglyceric acid to produce glyceraldehyde-3 phosphate, and regenerating RuBP so that they can accept a new atom of carbon from CO2 from the air.
9 molecules
*EXPLANATION*
the calvin cycle: three molecules of CO² fixed give a net yield of one molecule of glyceraldehyde 3-phosphat at the net cost of nine molecules of ATP and six molecules of NADPH

Genetically modified (GM) crops are foods that have had their genomes modified, allowing humans to increase the production of certain crops. Farmer A purchases GM seeds that are immune to a specific herbicide. She plants these seeds in rows over seventeen acres. The following spring, Farmer A's neighbor, Farmer B, tells her that nearly a third of the plants in his crop fields have the same immunity.
Which of the following describes the most likely explanation for this occurrence?
a.Rabbits which frequent both fields carried the seeds across to Farmer B's land.
b.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
c.The two farms share an irrigation system which transmitted the immunity from one field to another.
d.By increasing the genetic diversity in Farmer A's crops, they have out-competed the crops on Farmer B's land.
Answer:
B.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
Explanation:
Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination. Option B is correct.
Jumping Gene:
It is a concept in biology which says that the genes present in the one plant can transfer to another plant via pollination. They are also known as Transportable elements.
Here Herbicide resistant genes transferred to from Farmer A's plants to farmer B's plants.

What is the difference between dominant and recessive traits?
Answer:
Dominant trait is the trait that the offspring are more likely to have, like if a dominant trait is to have green eyes and the recessive trate is blue eyes, then the offspring are more likely to have green eyes, but its likely to have blue eyes too.
Dominant traits show up more than the recessive trait, because its stronger than the recessive trait.
Explanation:
Answer:
Dominant traits are traits that are always expressed when the connected allele is dominant. This is for even if only one of the copy of the dominant traits exist. Dominant traits are always written in capital letters. An example of dominants traits would be BB or Bb.
Recessive traits are traits that are only expressed if both of the alleles are recessive. A recessive trait is always written in a lowercase letter. An example of recessive traits would be "bb".
Also, Dominant traits are traits that are more common to people. It is strong. For example, if you are right handed, that is a dominant trait. Being right handed is a common thing in this world. 90% of the world's population is right handed.
On the other hand, recessive traits are traits that are rare to people. It is weak. For example, if you are left handed, that is a recessive trait. Being left handed is a rare thing for people in this world. Only 10% of the world's population is left handed.

Tay-Sachs disease is a genetic disorder that results in the destruction of neurons due to a buildup of sphingolipids in the cells. Which organelle is malfunctioning in Tay-Sachs
Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.
