Cross a person who does not have freckles and is heterozygous for dimples with a person who has
Alja [10]

Answer:

1. 1/2

2. 1/2

3. 1/4

Explanation:

Let the allele for freckles be A or a while that of dimples be B or b.

A person without freckles but heterozygous for dimples = aaBb

A person who has freckles (whose mother has no freckles) but no dimples = Aabb

      aaBb    x    Aabb

Offspring

4 AaBb - freckled and dimpled

4 Aabb - freckled and non dimpled

4 aaBb - non freckled and dimpled

4 aabb - non freckled and non dimpled

1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2

2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2

3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4

Suppose you discover a new organism. What would you expect to see if you studied it under a microscope?
weqwewe [10]
Since it is a organism, we know its a living thing.
Ex: Rock=not living=not organism

Plant=Living=Organism

If you studied it under a microsope, you would expect to see cells as every living thing has. A microscope is a tool used by scientist and are made to see very little things that our regular eyes and a magnifying glass cannot see. So you would see cells because cells are very very tiny

Compare and contrast the role of secretory vesicles, the lysosome, and the peroxisome.
Daniel [21]

Lysosomes ( common in animal cell but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion in white blood cells that eat bacteria) lysosomes contents are carefully released Into the cytoplasm can also cause cell death.  

Peroxisomes: this organelle is responsible for protecting the cell form its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria .The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.

Secretory vesicles: cell secretions –e.g, hormones, neurotransmitters, are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for releases.
