Only the last one provides an actual evidence of having a common ancestor. The rest can be a result of living in a similar environments that makes life easier. For example, many species live next to water, as water provides more fertile ground for plants, and they might have similar behaviors (searching for water) but they might not be closely related.
so the correct answer is D.
Answer:
A. a year that was cool or dry
Explanation:
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
Answer:
1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases
2) To hold the genetic info for the cell
3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus
4) To bring amino acids to the ribosomes to help build a protein
5) A chain of amino acids held together by peptide bonds
6) Ribosomes
7) Because those are the bases that are complementary in DNA so they must be equal
8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made
9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to be <u>convergent</u>.
A neuron in such a network can take information from numerous other neurons through convergence. Inhibitory interneurons are activated by presynaptic cells, but instead they reduce nearby cells inside the network.
Synaptic divergence refers to the dispersion of synapses from such a single neuron onto several postsynaptic partners as well as partner kinds, while synaptic convergence refers to being affected by having neuronal cell kinds delivering input around on a shared postsynaptic partner.
Multiple presynaptic cells send convergent information to a single postsynaptic neuron.
