what is the functional cell of the nervous system?
The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons and dendrites.
please mark brainliest.
The functional cell of the nervous system is neurons.
What is a nervous system?The nervous system is the main controlling system of the living body. It consists of the brain and the spinal cord. The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system.
Neurons are the cells of the nervous system. The cells are branch-like structures like the roots of a plant, they contain absorb the information using electrical impulses and transport it into different areas of the brain.
The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells. The neuron cells' function in the peripheral system is to collect the signals and information and to send it to the central number system, which contains the brain for processing.
Therefore, neurons are the functional cell of the nervous system.

Answer:
A. Ocean basins getting smaller or water returning to the hydrological cycle.
As ocean basins get smaller the amount of water on them does not dimish, this is why the sea level rises, same volume with less width you need more height, and as the water returns from the hydrological cycle, you add volume which makes the sea level go up.

if a cell at metaphase of mitosis contains 32 sister chromatids, how many chromosomes will be present in a g1 cell?
Answer:
16
Explanation:
because we are divid 32/2
If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.
During interphase chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes).
In G1, each chromosome is a single chromatid.At the G1 stage, the cell would have 16 chromosomes.Each chromosome has a single chromatid for a total of 16 chromatids in g1 cells.in metaphase sister chromatids are present and the number of chromosomes is 2n.Thus, If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.

Answer:
Active transport in plant
Explanation:
Active transport in plants
For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. Active transport then occurs across the root so that the plant takes in the ions it needs from the soil around it.

A. In an organism with more than one cell, each of its cells must perform all basic life functions to survive.
B. In an organism with more than one cell, some of its cells perform the basic life function of repairing cell damage and other cells do not.
C. In an organism with more than one cell, some of its cells perform the basic life function of getting rid of waste and other cells do not.
D. In an organism with more than one cell, each of its cells must perform one basic life function but not others.
Answer:
I think the answer is A
Explanation:
Because all cells must perform basic functions to survive
In an organism with more than one cell, each of its cells must perform all basic life functions to survive. Thus option A is correct.
what do you mean by cell ?
Cell is the basic unit of any living organism present in animal, plant, microbes etc; Bacteria are unicellular organism where as higher eukaryotic organisms are multicellular in nature like plants and animal cell.
Prokaryotic cells are the most simplest form of cell which have a cell membrane, cytoplasm, ribosomes where protein synthesis occur, and nucleoid genetic material are present, most of bacteria have cell wall, reproduce by binary fission.
The eukaryotic cells have all the organelles like it has outer covering cell membranes, cytoplasm, ribosomes, and nucleus, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum, Golgi apparatus for protein sorting and exporting.
It has mitochondria the power house, a cytoskeleton for structure of the cell and communication, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.
Thus option A is correct.

What is the purpose of the dietary food?Animals consume dietary food, and not all animals consume all foods. Some animals, such as the lions, are carnivores and eat animals, whereas others, such as the elephants, are herbivores and rely on plants for energy. The lion, as a carnivore, obtains the majority of its fats portion, proteins, and carbohydrates in the form of glycogen from other animal, whereas the elephant, as a herbivore, obtains the majority of its nutrients from plants such as carbohydrates, proteins from proteinaceous plants, and some lipids from seeds.
Hence, The elephant and the lion use macromolecules for energy, such as carbohydrates, proteins, lipids, etc., and these macromolecules, when broken down after digestion, give energy.
