Answer:
no
Explanation:
Human blood is red because of the protein hemoglobin. Hemoglobin contains a red-coloured compound called heme that’s important for carrying oxygen through your bloodstream
Sometimes blood can look blue through our skin, but its never blue. the reason we see blue is because blue light doesn't go as deep into kin as red. If the blood vessel is deep, your eyes see more blue than red light due to the blood’s absorption of red wavelengths.

Explanation:
In sexual reproduction, how many genes does an offspring receive for each trait?
Answer:
__________
Explanation:
In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.
Answer:
Each parents gives of half of the genes acquired by the offspring. 46 chromosomes or 23 pairs.
Explanation:
". Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes. Why? Well, when an egg and a sperm come together, which is a process called fertilization, they contribute 23 chromosomes each. Add 23 and 23 together, and you get one happy 46-chromosome-containing fertilized egg that can now develop into a new human.
Meiosis
Gametes are produced by a type of cell division known as meiosis. It's meiosis that reduces the number of chromosomes in the cell down to 23. It's also meiosis that makes gametes genetically different from one another. After the cell division takes place, each sperm and each egg has its own unique genetic makeup. In other words, meiosis can be thanked for giving Junior his cute mismatched ears. "

Explanation:
Can someone help me out with this? In pea plants, the allele for green seeds (G) is dominant over the allele for yellow seeds (g). • Parent 1: homo-zygous for green seeds • Parent 2: homo-zygous for yellow seeds. • What are the gametes each parent plant will produce? Parent 1: Parent 2:
Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes

centricles play specific roles during the division of
Answer:
Centrioles play a notable role in cell division. ... These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division. Though centrioles play a role in the mitosis of animal cells, plant cells are able to reproduce without them.

The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? *
A. Only the interaction between dominant genes.
B. Only the interaction between recessive genes.
C. The interaction between dominant and recessive genes.
D. The interaction between dominant and recessive genes does not determine inherited traits.
Answer:
c is right answer.
The interaction between dominant and recessive genes
Explanation:
Eye colour and blood groups are both examples of dominant/recessive gene relationships.
Eye colour
The allele for brown eyes (B) is dominant over the allele for blue eyes (b). So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.) However, if both alleles are for the recessive trait (in this case, blue eyes, bb) you will inherit blue eyes.
Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
HOPE THIS HELPED <3
Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.

What is the answer here?
A student attaches a rope to the handle of a chest loaded with a few books, while the other end of the rope is tied to a spring scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.
What can be concluded from the data?
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force decreases as the mass of the chest increases.
The amount of frictional force decreases as the mass of the chest increases.
Answer:
As the mass of the chest increases, more force is required to pull it.
Explanation:
Mass is a measure of the inertia of a body. Inertia means reluctance towards motion. A heavier object has a greater degree of inertia than a lighter object.
Hence, the student will notice that more force is required to move a heavier chest of books than a lighter one.
Therefore, as the mass of the chest increases, more force is required to pull it.
Which process is involved in the formation of a galaxy?
