Fraternal twins, while conceived at the same time, are not genetically identical.
Which statement best explains why these siblings are genetically different from each other
Answer:
Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

the process of activating photoreceptors by altering the photopigments is known as __________.
The process of activating photoreceptors by altering the photopigments is known as PHOTOTRANSDUCTION. It involves the mechanism by which light can be converted into electrical signals.
Phototransduction refers to the mechanism by which light can be converted into electrical signals.
Visual phototransduction occurs in the part of the eye known as the retina, in specific cells called photoreceptors and ganglion cells.
Photoreceptor cells include rod cells and cone cells, which are sensitive to light.

which body systems work together to provide oxygen to all cells within a human organism?
Answer:
Explanation:
For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
Answer:
The respiratory and circulatory
Explanation:
The respiratory system allows for someone to breath and The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.
In mitosis the daughter cells are identical to the parent cell. How do the cells produced during meiosis differ from those produced from mitosis
Answer:
The cells produced during mitosis are identical but cells produced in meiosis are different.
Explanation:
This is because in mitosis, there is no crossing over, but crossing over occur in meiosis. During crossing over, there is swapping of the genetic material.

what happened to the urine volume when the solute gradient in the interstitial space was increased?
The urine volume decreased when the solute gradient in the interstitial
space was increased.
The solute gradient in the interstitial space being increased means more
absorption of compounds into the bloodstream and vice versa. When this
occurs, the constituent of urine decreases.
The decrease in the urine components brings about a decrease in its
volume also due to increased absorption taking place.

Assuming diallelic genes, expressing complete dominance and not interacting, the predicted fractions are 4/16 Black Fur, Black Eyes - 4/16 Black Fur, Red Eyes - 4/16 White Fur, Black Eyes - 4/16 White Fur, Red Eyes
Available data:
Two traits are involved in this cross ⇒ fur color and eye color.Black fur color is dominant over white fur colorBlack eyes is dominant over red eyesThe cross is between a h0m0zyg0us recessive parent with a dihybrid one. What can we deduct about this information?
Assuming diallelic genes coding for each trait, expressing complete dominance, and no interaction between genes, we can propose the following genotypes and phenotypes.
Genotype Phenotype
BBEE, BbEE, BBEe, BbEe Black fur, Black eyes
bbEE, bbEe White fur, Black eyes
BBee, Bbee Black fur, Red eyes
bbee White fur, Red eyes
How to perform the cross?Cross: h0m0zyg0us recessive parent with a dihybrid parent
Parental phenotypes) White fur, Red eyes x Black fur, Black eyes
