Answer: 16 mm

Explanation:

If I understood the given equation correctly, it could be rewritten as:

size of image = size of real object * magnification

Plug in the given values, and we get

size of image = 0.8 * 20 = 16 (mm)

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

Proton pumps embedded in the cell membrane use ATP to move hydrogen ions across the membrane. Which of the following best descri
DIA [1.3K]

Answer:

Explanation:

Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.
