Answer:
Green chemistry, or sustainable chemistry, involves creation on the molecular level:
Explanation:
Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.
Explanation:
gene pairs - AABBCCDdEeFfGgHhIiJj
number of possible types of eggs - 1*2*2*2*2*2*2*2=128
reply "a" is good
Answer:
The correct answer is multicellular organisms.
Explanation:
Organs are differentiated structure formed by group of cells and tissues to perform the similar functions. When more than two organs perform specific function in a coordinated manner they form organ system.
Tissues and organs are a characteristic feature of multicellular organisms as more than one cell is present in these organisms and these cells aggregate together to form tissues, which further aggregate to form different organs carrying out the different functions attaining complexity.
Since, unicellular organisms do not have more than one cell, unicellular cells do not form tissues and lack organs.
Thus, the correct answer is multicellular organisms.
which is absent in unicellular organisms.
<h2>Answer:</h2>
An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen.
An obligate aerobe is an organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain.
An Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.
