Answer: To double the pressure, the temperature has to be 2*t1 K
Explanation: Gay-Lussacs law states: for a constant mass of gas held at constant volume, Pressure is proportional to absolute temperature (degrees K)
p1/t1 = p2/t2
we have p1/t1 = 2*p1/t2—> t2 = 2*p1*t1/p1 —> 2*t1

Which of the following methods uses the decay of atomic particles in an object to find its exact age? (3 points)
a
Fossil dating
b
Geologic dating
c
Radioactive dating
d
Relative dating
Answer:
C. Radioactive dating
I know this because radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the fossil, organism, and/or material.

(REPOST)if something needed to enter the cell and couldn't go through the phospholipid bilayer, how else could it enter the cell?
Answer:
by being facilitated
Explanation:
If something needs to enter the cell and could not go through the phospholipid bilayer, it could be assisted through a process known as facilitated diffusion.
Facilitated diffusion involves the passive movement of molecules that will ordinarily not pass through the phospholipid bilayer of the cell membrane through the help of the channel or carrier proteins.
If the phospholipid bilayer will not allow some molecules to pass through it as a result of a concentration gradient, the channel/carrier proteins form a special passage and the molecule is facilitated by such passage to move across the membrane.

Parents that are heterozygous for having freckles (dominant) are crossed. Which correctly describes their offspring?
O Twenty-five percent have freckles.
O Twenty-five percent are Ff.
O Seventy-five percent have freckles.
O Seventy-five percent are Ff.
Answer:
In a cross of parents heterozygous for having freckles, the ratio of their offspring is (C) Seventy-five percent have freckles. Let allele F be dominant and allele f be recessive. Heterozygous parents will have genotype Ff.
Explanation:
Seventy-five percent have freckles.
What is homozygous dominant genotypes?Homozygous dominant is a genotype that consists of two dominant alleles for a gene.
What is heterozygous dominant in biology?'heterozygous' organism for a particular trait means that it possesses dissimilar alleles (e.g. Aa); one of the alleles is dominant and the other is recessive.
Hence, C is correct option

4. Would a mutation in a red blood cell be passed on to offspring? Explain your answer
Answer:
The mutation that takes place in the somatic cells are not carried from one generation to another generation. The mutation in the red blood cells cannot takes place because the red blood cells does not have nucleus in them.
Explanation:
Mutations occuring in somatic cells can not be carried from one generation to another. Mutations within red blood cells are unable to take place because the red blood cells themselves don’t contain a nucleus.
Organism A can carry out cellular respiration. Organism B can carry out only glycolysis. Which organism will be able to use more of the energy in a molecule of glucose? Explain your answer.
Answer:
...
Explanation:
It is definitely organism A. Cellular respiration has a net of 32 molecules of ATP while glycolysis only has 2. This is because cellular respiration involves Kreb's cycle which causes the molecules to be constantly reduced and oxidized as electrons move from one molecule to another. This Is known as the electron transport chain. This releases a molecule of ATP every time a redox reaction occurs.
The sides of a DNA molecule are made up of sugar molecules alternating with ___________ molecues.
Answer: phosphate
Explanation:
Deoxyribose nucleic acid, which is commonly referred to as DNA simply carries genetic information in an organism. The m DNA is made up of two nucleotides strands.
Nucleotides are simply the DNA's building block. It should be noted that the sides of the DNA consist alternating sugar molecules and the phosphate groups.

Sandra is heterozygous for eye shape.
What does this mean?
She has two of the same alleles for eye shape, one from each parent.
She has two different alleles for eye shape, one from each parent.
She has only one allele for eye shape, which she received from one parent.
She has two alleles for eye shape, both from the same parent.
Awnser:
She has two different alleles for eye shape, one from each parent
You always receive 1 allele from each parent, and you're heterozygous, those alleles are different.
Sandra is heterozygous for eye shape, this means she has two different alleles for eye shape, one from each parent. The correct option is b.
What is heterozygous?Heterozygous means the person who has different alleles from each parent for the same type of character. There are two types of people, heterozygous, which contain different alleles for the same character. Homozygous, which means he has only one allele for one character.
Sandra has two alleles for eye shape, which means she got different eye shapes from her father and mother. She got two eye shapes, and now the allele which is dominant will be shown in her phenotype of Sandra. The other will be recessive.
Therefore, the correct option is b, She has two different alleles for eye shape, one from each parent.

name the organ that is adapted for gaseous exchange in humans
Answer:
Lungs.
Explanation:
Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..
what are the steps in cellular respiration?
There are three main stages in the cellular respiration
1.Glycolysis
Glucose is turned into two molecules of pyruvate. This process takes place inside the cytoplasm and does not require O2
2.Kreb's cycle(TCA cycle)
This proces takes place in the mitochondrial matrix.Electrons are incorporated in the molecules that will be used in the next step.
3.Electron transport chain
This process takes place in the mitochondrial membrane. Energy from the electrons resulted in the krebs cycle is used to pump protons in the inter membranous space to form an electro chemical gradient. This will lead to the oxydative phosphorilation(ATP synthesis)

Several kinds of specialized cells work together to create the sense of hearing. Hair-shaped cells sense vibrations and nerve cells send signals to the brain. Structural cells hold the hair cells in place. No matter their specialty, which functions must all cells perform to survive? Choose the three statements that apply.
Answer:
The correct answer is -
bringing in nutrients and water,
getting rid of wastes, and
obtaining energy.
Explanation:
All cells no matter what type of cell they are or their specialty, they need to bring water and nutrients to work properly and survive. These cells also need to remove cellular waste to prevent toxicity in the cell. All the toxic material or metabolic waste must be removed from the cells.
All the cells of the bodu=y including hair-shaped cells or structural cells all required energy to perform their function therefore obtaining energy is one of essential function cell need to be performed.

Max tried an experiment in which he added red-dyed salt water to clear freshwater. He noticed that a lot of the red water sank below the clear water. Which of the following statements explains why this happened?
a. Adding salt to water makes it more dense.
b. Adding salt to water makes it less dense.
c. Adding salt to water decreases its temperature.
d. Adding salt to water increases its temperature
Answer:
A
Explanation:
Adding salt to water causes its density to increase. Denser water will sink below less dense water.
As salt water is denser and will sink at the bottom and adding the salt raises the temperature of water body and hence will make it more warm and saline.
A max tries to add red dyed salt water to clear the fresh water he sees a red color sinking below the fresh water that is cool.The option D is correct.
