Answer: Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
Explanation:
Answer: FALSE
Explanation:
The plasma membrane has both Na –K channels across it walls. They are membrane transport proteins which hydrolyse ATP s for the active transport mechanisms for transport of sodium and potassium ions across the plasma membranes .
Naturally,there are more potassium ion channels than sodium channels in plasma membrane; potassium is also extracellular while sodium is extracellular
Therefore ,when some potassium ions diffused into the Axoplasm, from the extracellular medium;;some potassium ions still move out BACK into the extracellular environments. Not all potassium are restricted from leaving .
This leakage occurs because of more available potassium ions channels than sodium ions, and higher number of available potassium ions
Thus the answer is FALSE
the ratio of diffusion <u>is 3 sodium out to 2 potassium in </u>
Out of the choices given here, a literary analysis contains a thoughtful interpretation of a work. The correct answer is A.
Answer:
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division. Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
Explanation:
The answer is an ovary.
The carpal is the female part of a flower and it consists of the style, stigma, and ovary. After pollen lands on the stigma, pollen tube begins to grow until it reaches an ovule which is inside the ovary. A<span> nucleus of pollen will fuse with a nucleus of the ovule and that fertilization will occur. A fertilized ovule becomes seeds surrounded by the ovary which matures and becomes the fruit.</span>
