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.

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.

Can anyone eXpLaiN what competition, mutualism, parasitism? Please and thank you. <3
Answer:
parasitism is when one animal harms another like a parasite. for example mosquitos and humans have a parasitism relationship because mosquitos harm humans. in total parasitism means the relationship in which one benefits and the other is harmed. mutualism is when both benefit and no on is harmed. an example of mutualism is when oxpecker (a kind of bird) eats the bugs off of a rhino, the rhino gets pest control and the bird gets food. and competition is the relationship between organisms that need and search for the same resources in the same place. for example predators of different species search for the same prey.
i hope this helped!!
Explanation:
in total parasitism means the relationship in which one benefits and the other is harmed
mutualism is when both benefit and no on is harmed.

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.

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.
(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.

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..

Explanation:
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.
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.

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)
