Plants are classified asA. multi-celled eukaryotes.
B. multi-celled prokaryotes.
C. single-celled eukaryotes.
D. single-celled prokaryotes.

Answers

Answer 1
Answer: The correct answer is A: Multi-Celled Eukaryotes

Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. ... This includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, and excludes the red and brown algae.

Hope this helps!
Answer 2
Answer: The answer is, "A", "Multi-Celled Eukaryotes".

Organisms that have two identical alleles for a particular trait are said to be a. hybrid.
b. homozygous.
c. heterozygous.
d. dominant.

Answers

Answer:

B. Homozygous

Explanation:

Homozygous organisms have two identical alleles for a trait. They may have two copies of dominant alleles or two copies of the recessive allele of a gene. For example, both RR and rr are homozygous genotypes. However, a heterozygous or hybrid genotype has one dominant and one recessive allele for a gene. Here, "Rr" genotype would be an example of hybrid or heterozygous genotype.

Final answer:

In genetics, organisms with two identical alleles for a specific trait are considered 'homozygous'. These can be either homozygous dominant or homozygous recessive, with the distinction depending on the specific alleles that are identical.

Explanation:

Organisms that have two identical alleles for a particular trait are said to be b. homozygous. This term is used in genetics, the branch of biology, for discussing the inheritance of traits. In this case, the two alleles inherited from parent organisms, one from each, are identical. For example, if a plant genotype is AA or aa for a specific trait, like height, it is considered homozygous, either homozygous dominant (AA) or homozygous recessive (aa).

Is green light most or least useful in photosynthesis? Why?

Answers

Green is the least useful light for photosynthesis. We know that becsuse plants look green, so we know that the plant doesn't absorb green. It just discards it.
it is least useful or effective in photosynthesis,,,
 because
the chlorophyll where light is trapped is itself green in colour...
so when sunlight falls on it ,, it traps all lights but not the green colour... and reflects green light so this green is not used or least used as it is reflected....
also plants appear green due to this reflection....

Red-green color blindness is due to an X-linked recessive allele in humans. A widow�s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele.Consider the following family history:
A man with a widow�s peak and normal color vision marries a color-blind woman with a straight hairline.
The man�s father had a straight hairline, as did both of the woman�s parents.
Use the family history to make predictions about the couple�s children.
Drag the correct label to the appropriate location in the table. Not all labels will be used.
What is the chance that any daughter the couple has will be color blind with a straight hairline?

Based on the exercise data we know that the couple genotype for red-green color blindness is:

(XY     x     X'X')

     X'        X'

X    X'X      X'X

Y   X'Y      X'Y

And the genotypes for widow's peak are:

  (Aa   x  aa)

     a      a

A   Aa   Aa

How many genes do people have ?

Answers

The amount of genes we have is considered an estimation. Theyused to believe it was around or above 100,000. Then when the human genome project (HGP)was completed in 2003 their estimation brought it down to 20,000 to 25,000. Youcan find their current work at “national human genome research institute” andalso a free public database.
