In the experiment determining the parental genotype of plant seedlings from a monohybrid cross, if the dominant color was green

(C) and the recessive color was white (c), what would the parental genotype have been if plate 1 only contained white seedlings instead of all green

Answer:

cc × cc

Explanation:

This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).

In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.

Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).

Answer:

c. mid-adulthood

Explanation:

This stage of life when gray hairs  become overwhelming in number and he has more gray hairs than brunette( brown hair) is called middle adulthood. Middle adulthood spans from 20 to 40 years of life which may be defined differently for different culture and country.

Robert is in his late mid adulthood somewhere near 40 at this age hair generally grow grey.

Can someone please help me
Usimov [2.4K]

Answer:

1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers

1B - Skeletal = bones

1C - Muscular = muscles

1D - Digestive = stomach, large/small intestine

1E - Circulatory = heart, veins and arteries

2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive

3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.

Can someone help me pls....<br><br> Describe the chemical structure of a carbohydrate?
Dafna1 [17]

Answer:

Carbohydrates consist of the elements carbon (C), hydrogen (H) and oxygen (O) with a ratio of hydrogen twice that of carbon and oxygen. Carbohydrates include sugars, starches, cellulose and many other compounds found in living organisms. In their basic form, carbohydrates are simple sugars or monosaccharides.

Sometimes, when Mendel crossed two pea plants with each other, he obtained a phenotypic ratio of 3:1 purple-flowered pea plants
vladimir1956 [14]

Answer:

heterozygous purple pea plant and heterozygous purple pea plant

Explanation:

Suppose the gene controlling flower colour in pea is P. Allele P is dominant over allele p. So, PP and Pp produce purple flowers and pp produces white flowers. If two heterozygous purple pea plants (Pp) are crossed :

Pp X Pp :

    P     p

P  PP  Pp

p  Pp  pp

As evident, the progeny will have genotypic ratio of 1 : 2 : 1 ( PP : Pp : pp ) and phenotypic ratio of 3 : 1 ( Purple : white )

Hence two heterozygous purple pea plants will produce 3:1 ratio of purple to white pea plants.
