Help please I'm so confused

Sergio [31]

Hi,

Attached is solution diagram. You can see that true breeding means both have same alleles for purple PP and white WW flowers.

They were crossed to produce hybrid plants that all had purple flowers PW because purple was the dominant trait.

However, upon self fertilization of those hybrid plants, both purple and white flower plants were produced in 3:1.

Hope it helps!

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

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

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

A plate moves 200 m in 10,000 years. What is its rate in cm/year?

schepotkina [342]

Answer:

1m = 100cm

200m = 20000cm

10,000years = 20,000cm

1 year = 20,000/10,000

= 2cm

It's rate is 2cm/year

The answer is option b.

Hope this helps.

What do the migration routes of homo sapiens reveal about their survival skills and ability to adapt?

garik1379 [7]

The migration routes of Homo sapiens reveal that they went through many environmental and physical challenges but adapted everything much quickly in comparison to the other animals. The evolution allowed other species also to adopt these changes but it took them a long time to fit in the new environment, a sub species of a species adopted the new and the previous one could not, but Homo sapiens invented ways and tools to combat and evolve much quickly. It included their living, dietary needs, clothing and much more.

The phrase “too large or too charged” is a helpful way to remember what kinds of molecules need to cross the cell membrane via a

saveliy_v [14]

Answer:

Due to their hole size.

Explanation:

Some molecules can pass directly through the phospholipid bilayer because of their small size which can easily pass through the small holes of phospholipid bilayer, while those that are too large or too charged need to pass through a membrane protein because membrane protein has a large holes through which large molecules can easily pass through the semi-permeable membrane of the cell by active or passive transport.
