The blockage of cerebrospinal fluid (csf) outflow in the brain can cause accumulation of fluid, resulting in cranial enlargement
alisha [4.7K]

The correct answer is hydrocephalus.

Hydrocephalus refers to the condition in which the accumulation of fluid takes place in the ventricles (cavities) deep inside the brain. The excess fluid enhances the size of the ventricles and applies pressure on the brain. The cerebrospinal fluid usually flows via the ventricles and bathes the spinal column and the brain.

Why do methane is a gas at room temperature and water is a liquid, even though both molecules are similar in size and mass?
emmainna [20.7K]

Answer:

Water can hydrogen bond.

Explanation:

Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.

Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.

Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.

Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.

<u>*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*</u>

If you could genetically modify a livestock organism, what would you modify and what
alexdok [17]

Answer:

Genetic modifications to livestock would most likely suit to increase their longevity and marketability.

Explanation:

One of the bigger problems facing livestock is disease. Genes for bacterial resistance would likely increase the yield of livestock over time. Additionally, livestock raised in hot/cold climates could benefit from genes that adapt them better to these conditions. For example, cattle raised in hot conditions would benefit from genes that increase sweating or decrease passive water loss like through defecation.

Additionally, tailoring livestock to consumer desires would increase marketability, and therefore profit. For example, an ideal steak has a set fat content. Genetically modifying cows to maintain this fat content would increase the value of its meat.

Scientists have been studying threats to coral reefs. The figure below shows where threats to reefs have increased (dark shading
erastova [34]
Since you are trying to investigate the possible variables that contribute to reef threats, it is advisable that you do an environmental study between two reefs that have characteristics that are similar or are closely similar. With this, you will be able to identify which is the primary cause of reef threats. Thus the correct answer is B.
