Answer:
The options are missing in the question, the options are;
a. an archaean
b. a Paramecium
c. a yeast (fungus) cell
d. a grasshopper cell
The correct answer is A (an archaean)
Explanation:
Archaea and Bacteria are domains where prokaryotes are commonly found. Archaea and Bacteria as prokaryotes are unicellular organisms that lacks membrane-bound organnelles and a well defined nucleus, in the sense that unlike eukaryotic cells, a nucleus does not house their genetic material (DNA), instead their single circular chromosome is nakedly localized in a region called the NUCLEOID.
In addition, prokaryotic cells lacks many organnelles found in eukaryotic cells e.g mitochondria, Endoplasmic reticulum, lysosome etc. The few ones like ribosomes found in their cytoplasm are not enclosed by lipid bilayers called membranes.
<span>The correct answer, according to Lamarck's theory of evolution, is that A) "Land mammals progressively modified their organs to survive in water. These features were passed on to the next generation, and the mammal gradually evolved into today's aquatic mammals."
Lamarck believed that animals could (a) acquire the traits that they needed and (b) pass those acquired traits on to their offspring. According to part (a) of Lamarck's idea, if I needed to be a faster swimmer (if I were an athlete), I could modify my body to have webbing between my toes, which would allow me to beat the competition! Also, according to part (b) of Lamarck's idea, if I were a body builder and developed (acquired) very large muscles through my training, then my children should be born with very large muscles. Based on the these examples, you can see why Lamarck's theory of evolution is not the one that is generally accepted by scientists. Rather, Darwin's theory of evolution, in which the traits that we are born with confer either an advantage or disadvantage to us in our particular environment, which determine whether or not we are successful (ie, survive and reproduce). New traits come about randomly by mutation, not by our need for them.</span>
Answer: This is True
Explanation: DNA is copied and carried down into generations every time an organism sexually reproduces.
