Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Answer:
Tissue forceps are used in surgical procedures for grasping tissue. Often, the tips have "teeth" to securely hold a tissue. Typically tissue forceps are designed to minimize damage to biological tissue.
Answer:
We know that there are 200 guanine bases so there will be 200 cytosine bases also.
According to Chargaff’s base pair rule,
G+A=T+C=600,
A+200+T+200=600 (since total bases are 600)
A+T+400=600
A+T=200
since there is 50% adenine and 50% thymine , A=100, T=100, G=200, C=200
Verification
A+T+G+C=600
100+100+200+200=600
600=600

Answer:
The correct answer is non-disjunction at the time of meiosis.
Explanation:
A disorder, which takes place in males exhibiting an additional X-chromosome and is an outcome of an error in cell differentiation resulting in anomaly known as the Klinefelter's syndrome. Due to non-disjunction the egg or the sperm may acquire an additional X-chromosome. When these unusual cells take part in the genetic makeup of a person, then that individual most probably suffers from the condition termed as Klinefelter's syndrome.
In the majority of the circumstances, the division of the cells takes place generally during the development of the sperm, and at the same time, there may be certain errors at the time of egg development. Generally, the condition is mostly seen in the offspring of women that conceive after the age of 35.
The 7-month-old infant is accustomed to
having the perineal area exposed and cared for and is not in a developmental
stage in which fears related to sexuality are present. A "clean
catch" at this age is often contaminated; therefore catheterization has
been prescribed. The parents do have the right to refuse, but this concern is
not realistic an infant of this age. The parent's concern is not appropriate
for the developmental age of the infant.
