Answer:
The use of left arm is more compared to right hand
Explanation:
In the given question, the anthropologist when examines the left and right arm he found that the left arm is thicker than the right arm.
The more thickness of the left arm signifies that the person uses his left arm for the muscular work as the more use of hand increases the deposition of the calcium phosphate and sulfate in bones along with other material which increases the thickness for the bones and increases the strength.
Thus, The use of the left arm is more compared to the right hand is correct.

광합성 과정에서 햇빛 에너지는 물을 산소와 수소로 분해하는 데 사용됩니다.
Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
Answer:
<u>The cork cambium produces cork and phelloderm.</u>
Explanation:
Cells' structural components decide their function. Cells arrange themselves into tissues, where specialized cell types carry out their functions in tandem. As cells mature, their function may even change over time, as they undergo certain subcellular changes in protein expression and signaling.
In larger plants, rigid tissues are needed to help support their modified stems, and transport water, minerals, other nutrients and food to different regions. Cork cambium is an unspecialized tissue found in the outermost plant layers. These act as meristematic regions; here, new tissues arise, growing outwards- these include:
- phelloderm- they mature into inner secondary cortex
- cork- dead air-filled cells called cork that form a strong protective layer on the stems of woody vascular plants.
