i agree
neuron undergoes mitosis, two daughter cells are produced, one daughter cell is a stem cell, one daughter cell is identical to neuron
Explanation:
neuron undergoes mitosis, two identical daughter cells are produced, daughter cells divide to produce stem cells. neuron undergoes mitosis, two daughter cells are produced, one daughter cell is a stem cell, one daughter cell is identical to neuron.

Explanation:
Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
Answer:The answer is the second option from the top: Anoxic waters create a harsh environment that does not support marine life.
Explanation: Looking at the table, the amount of dissolved oxygen water (which enables marine species to breathe underwater) at station 138 is 0.02mg/liter compared to 1.5mg/liter, much lower than at station 137. Anoxic means "lacking oxygen", which sharks need to survive. So a lack of oxygen in a particular region will limit the number of sharks able to survive or live in that region.
Assuming this is a blank free fill question, a whole prehistoric insect could be found trapped in amber.
