What evidence is there that modern archaebacteria may be most like the hypothesized earliest cells on Earth?
Both archaebacteria and early cells share morphological similarities,
including a membrane-bound nucleus.
Photosynthesis allows both archaebacteria and the earliest cells to harness
energy from the Sun.
Archaebacteria thrive in extreme environments of intense heat or pressure,
and microfossils suggest early life forms lived in volcanic environments.
Archeabacteria can only survive in warm, shallow waters similar to the
primordial seas in which cells evolved on early Earth.

What does the hardy-weinberg principle relate to? a. chances of survival of an organism b. frequency of alleles in a population c. natural selection in a species d. causes of evolution among organisms

Which of these transport mechanisms moves glucose from the blood into a cell? active transport diffusion facilitated diffusion osmosis

Abody cell has been growing and at synthesis proteins.in the nucleus of this body cell,dna replication is taking place. and a copy of the cells genetic material is copied.which of the following is the best conclusion you can make about the life cycle of this cell ? a) the cell is ready to undergo mitosis.and a chemical signal will send the cell to prophase b)the cell is undergoing meiosis and will cross over the genetic material next c)the cell is in the s phase of interphase and will move next to the g2 phase d) the cell is in the g2 phase of the interphase and is ready to begin diving
