Answer:

EeWw

Explanation:

The allele for the earlobe is depicted as e while that of the hairline is w.

A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.

The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww

eeWW x EEww

During meiosis, each genotype will form gametes.

eeWW: eW, eW, eW, eW

EEww: Ew, Ew, Ew, Ew

These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:

eW x Ew

<u>offspring</u>

100% EeWw (see the attached image for the Punnet's square)

<em>The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline. </em>

Calculate the actual size of the organelle (A to B). Show all your workings in microns (um). <br>

fredd [130]

To measure the diameter of a organelle with a scale line of 1 µm.

Measure the length of the scale line on the micrograph in mm, e.g. 1 µm = 17mm.
Measure the diameter of the organelle in millimetres, e.g. = 60mm.
True diameter of organelle.

<h3>How do you find the actual size of an organelle?</h3>

To calculate the actual size of a magnified specimen, the equation is simply Mixed6 :

Actual = Image size (with ruler) ÷ Magnification.

Thus, this is how we can measure the size of an organelle.

Damian grew a plant from a leaf cutting. How did the plant reproduce?

ycow [4]

A plant grew from a leaf cutting will reproduce asexually.A plant cutting refers to a piece of plant that is used to vegetatively propagate a plant. A plant cutting can be a piece of stem, root or leave. The plant cutting is usually placed inside a suitable medium, where the cutting will grow to produce a new plant under suitable conditions. Plants that are grown from plant cutting are considered to be reproduce asexually, because vegetative propagation is a form of asexual reproduction.
