Answer:
Cells, tissues, organ, organ systems, organism
Explanation:
All living organisms including Lisa as used in this question is made up of fundamental and basic unit called CELLS.
In multicellular organisms (more than one cell), these cells undergo multiplication by dividing repeatedly and the ones that perform similar functions forms the TISSUE. For example, in humans like Lisa, we have the blood tissue formed by blood cells performing similar functions e.g erythrocytes, leukocytes etc.
The tissues that work together to perform a certain function groups together to form an ORGAN. An organ performs a specific function in the body. Examples of organs in a living organism like Lisa is heart, Kidney, liver etc. These organs, whose, functions are in synchrony collectively forms the ORGAN SYSTEM, which helps maintain the internal environment of an organism. Organ systems include; circulatory system, digestive system etc. Each organ system is made up of certain organs.
The collaboration of many organ systems working together ultimately forms the full ORGANISM like Lisa who is a human.
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies
:
- <em>Red eye (R) is dominant trait.
</em>
- <em>White eyes (r) is the recessive trait.
</em>
When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square
:
<em><u>Rr X Rr
</u></em>
<em>Alleles R r
</em>
<em>R RR Rr</em>
<em>r Rr rr</em>
In the offspring, the probabilities are:
- 50% heterozygous individuals Rr, with red eye phenotype.
- 25% pure dominant individuals RR, with red eyes
- 25% individuals with the recessive rr genotype, white eyes.
<u>This is the possibility of two red-eyed flies having white-eyed offspring</u>.
The question is incomplete as it does not have the options which are:
a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
b. The woman may have different gender babies.
c. The woman with less stretch marks has larger skin cells.
d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.
Answer:
The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
Explanation:
The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.
These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.
Thus, the selected option is correct.
Answer:
The answer is B) monomer of starch and cellulose.
