Ependyma cells. These cells
that make up the neuroectodermal padding is responsible for the production of cerebral
spinal fluid. The cells are one type of neuroglia
cells of the central nervous system. The lining of ependyma cells of the brain also
plays a role in neuroregeneration.
(1) volume is given by
Volume=length*width*height=10cm*5cm*3cm=150 cm^3
(2) Density = mass/volume = 180 g / 150 cm^3 = (180/150) g / cm^3 = 1.2 g / cm^3
(3) Mass is independent of gravity, so the solid will have the same mass on the moon, on mars or any other planet.
Weight is the product of mass and acceleration due to gravity. Acceleration due to gravity on earth is 9.8 m/s^2, while on the moon, it is 1.62 m/s^2. Therefore the solid has a different weight on the moon than that on earth.
(4) If an object sinks in (pure) water, the density must be greater than one, since (pure) water has a density of exactly.1.0.
(5) Not all solid with he same dimensions have the same density, which depends on the nature of the material. Wood is lighter than water, while iron has a density of 7.8, gold has a density of 19.3, etc. However, all objects having the same dimensions have the same VOLUME.
(6) SI (Système International) is a unit based on metre, kilogram and second for length, mass and time measurements.
(7) Remaining definitions can be looked up in your textbook. If you need further definitions, please post.
Answer:
The inner membrane of the mitochondrion is folded into cristae. The cristae
<u>increase</u> the surface area of the inner membrane, <u>enhancing</u> the mitochondrion's ability to produce ATP through <u>cell respiration</u>.
Explanation:
Options for this question are
- <em>increase - inhibiting - photosynthesis</em>
- <em>decrease - enhancing - cell respiration</em>
- <em>increase - enhancing - cell respiration</em>
- <em>decrease - inhibiting - photosynthesis</em>
Mitochondria are the organelles in charge of energy production inside the cell. For the mitochondrion to achieve its goal, a series of metabolic processes must occur, that require the presence of oxygen and organic substrates.
Mitochondrial cristae are the configuration of the mitochondrial internal membrane, with the purpose of increasing the surface where metabolic reactions and the electron transfer chain occur, in order to obtain ATP molecules, during the process of oxidative phosphorylation, also called cellular respiration.

Answer;
Natural selection
Explanation;
-Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Genetic diversity allows the different organisms to have different physiological characteristics. Some of them provides them with genetic resistance, others don’t. The ones which are resistant survive the pesticide, others don’t ; this is known as natural selection.
-Those that are resistant will live longer and have a larger number of offspring (reproductive success). From one generation to another, there will be more and more resistant pests (because of their larger offspring), and less and less pests that are not resistant (because they tend to die young). If the selection process goes on, someday the pesticide will be useless (it will kill no pest).
Yes, because homologous structures are different structures we have that other different organisms might have. humans and monkeys both have arms, although they are completely different species, this can tell scientists that they could have shared a common ancestor in the past, and may have evolved
