Nerve cells do not begin to develop until after a child is born
true or false

Answer:

False

Explanation:

hope this helps :)

Nerve cells do not begin to develop until after a child is born, which is false, as they begin to develop well before birth, and the process of neuronal development starts during embryonic development.

Neurons are generated from specialized cells called neural stem cells, and then these neurons migrate to their final positions and begin to form connections, or synapses, with other neurons to form the neural networks, and these connections continue after birth and are influenced by experience and environmental factors.

Hence, nerve cells do not begin to develop until after a child is born, which is false, as they begin to develop well before birth, and the process of neuronal development starts during embryonic development.

Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.

Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.

What is the independent variable in this experiment?

The efficiency of photosynthesis varies with the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher labeled the CO2 supply to the algae with 14C, and the H2O with 18O.

Which of the following results is expected?

More 14C is found in the algae when it is illuminated by green light than when it is illuminated by violet-blue and red light.
More 18O is found in the algae when it is illuminated by green light than when it is illuminated by violet-blue and red light.
