Answer Options:
a. Cells are the basic units of structure and function in living things.
b. New cells are produced from existing cells.
c. All cells enclose their DNA within a nucleus.
d. All living things are made up of cells.
Answer:
a. Cells are the basic units of structure and function in living things.
b. New cells are produced from existing cells.
d. All living things are made up of cells.
Explanation:
Cell theory states that cell living organisms are composed of at least one cell, which are the basic unit of life.
Cells are always produced from other living cells, and cannot spontaneously generate.
However, not all cells enclose their DNA within a nucleus, prokaryotic organisms (bacteria) do not possess a nucleus but still have DNA

According to kagmi on yahoo these are three lines of evidence that support the theory of evolution.
The fossil record shows the existence of billions of extinct species. It also shows a clear progression from one species to the next; there are many "transitional fossils," such as the archeoptryx (probably spelled that wrong, lol) which is clearly an intermediate in the evolution of dinosaurs into birds.
<span>Biogeography shows the distribution of species, providing further support that different species can and do evolve from common ancestors. Australia has many species of marsupials not found on other continents, for example; this implies that these species may have shared a common ancestor which lived on Australia when it was separated from the other continents by continental drift. </span>
<span>Molecular biology allows us to analyze genes and proteins down to the very molecules that make them up. This reveals many similarities and differences between organisms not readily apparent to the naked eye. We can see, for example, that humans share the vast majority of their DNA with all mammals; slightly less with reptiles; slightly less with amphibians, and so on. We find that species' DNA sequences match up well with the fossil record in terms of how closely related the species are. </span>
True statement. Sperm are continuously produced by males, while a female is born with a full supply of eggs.
Characteristics of egg cells and sperm cells.
*Egg cells are usually formed in a female before birth while sperm cells form during puberty.
*Egg cells are produced in the ovary of a female human being while sperm cells are produced in the testicles of a male human being.
*Egg cells are included in the largest cells in a female body while sperm cells are the smallest cells in the male body.
*Only a single egg cell is produced during ones menstruation cycle while millions of sperm cells are released during a single ejaculation.
*Egg cells formed before birth and are active only until female menopause while sperm cells production started during puberty until death of the male body.
