Chromosome Gene Nucleus
Answer:
Nucleus
Chromosome
Gene
Explanation:
A simple explanation is that genes make up chromosomes, and chromosomes are located inside the nucleus. DNA is a thin, long string of codes and sequences that are basically the blueprint for making YOU. Genes are sections of DNA that are then shaped into a chromosome. Usually, 46 chromosomes are inside the nucleus. Having more or less chromosomes can lead to genetic problems.

How could our baby be an albino?
Tiffany and Joe have just had a baby and are very surprised to learn that their baby is albino with very pale skin
and hair color. Tiffany's sister has come to see the new baby, so Joe goes out to talk with his sister Vicky.
Did Tiffany have an affair?
Joe is very angry. He tells Vicky, "I think Tiffany had an affair with Frank! He's the only albino we know.
Obviously, Tiffany and I aren't albino, so Frank must be the father."
Luckily, Vicky remembers her high school biology, so she explains, "Two parents with normal skin and hair
color can have an albino baby, if they are heterozygous and carry a recessive allele for albinism."
She draws a Punnett Square to show this. Draw the Punnett Square. Use A for the dominant allele that
results in normal skin and hair color and a for the recessive allele that can result in very pale skin and hair color
Upload an image of your Punnett square.
Answer:
If both parents are heterozygous, there is a 1/4, 25%, 0.25 chance that the baby turns out albino.
Explanation:
Using A as the dominant allele and a as the recessive allele, I made a quick Punnett Square and attached it below. The outcomes are AA, Aa, Aa, and aa. I hope it helped! :]

How can an atom, that was once part of the rat's body, could become part of a bird's body?
Answer:
Explanation:
it could get rearanged atoms move to make objects like a dimaond is just carbon aranged different
The rat gets eaten by a bird, indicate that an atom, that was once part of the rat's body can become part of a bird's body.
What is food chain?"It is the sequence of transfers of matter and energy in the form of food from organism to organism."
The plants are producer that makes their own food in the presence of sunlight. The grasshopper which is primary consumer eats plants. The grasshopper gets eaten by the secondary consumer, rat. The tertiary consumer which is a bird will the eat this rat.
As we know that according to the law of conservation of matter, matter can neither be created nor destroyed but can transformed from one form to another. And the matter consists of atom.Hence, according to law of conservation of matter, an atom, that was once part of the rat's body can become part of a bird's body.

parent plant in order to have access to
enough light and moisture.
B-Seeds with unusual forms are not
attractive to animals, so they are not
eaten.
C-Seeds are camouflaged within the
parent plant so that they are not eaten

What is the role of structure A? Check all that apply.
to attract pollinators
to contain the pollen
to contain the egg and ovule
to surround the flowering bud
to protect the reproductive parts of the flower
Answer:
to attract pollinators
Explanation:
The role of structure A is to attract pollinators. Pollinators are the organisms which helps in the pollination of flowers. These organisms gets nectar from the flower. During their contact with flower pollens are attached to their body and when they moves to another flower these pollens falls on the carpel of the flower and as a result pollination occurs that leads to formation of seed.

Answer:
May be Nutritional but no sure
Diet and stress are mostly examples of nutritional type of factors. Thus, option C is correct.
What is the example of Diet and stress?
Diet and stress are mostly examples of Nutritional factor, Eye color is mostly caused by Genetics. The structure of human eye is an important sensory organs which is responsible for vision, differentiation of color that is 10 – 12 million colors and maintain the biological clock of the human body.
The internal components of an eye are Lens which are transparent, biconvex attached to the ciliary body with the cornea it refracts light. Retina is the innermost layer of the eye, light sensitive and acts as a film of a camera, ganglion, bipolar and photoreceptor cells are present in retina.
It involve in the conversion of the image into electrical nerve impulses used for the visual perception.Optic nerve located at the posterior portion of the eyes which carry all the nerve impulses from the retina to the brain for perception.
Therefore, Diet and stress are mostly examples of nutritional type of factors. Thus, option C is correct.
