Which compound would most likely experience only london dispersion forces between its moleucles?
The nonpolar compounds are most likely to experience only London dispersion forces between molecules
When two atoms share electrons evenly, a type of chemical bond known as a non-polar covalent link is created. The number of electrons shared by the neighboring atoms in an atom will therefore be equal. Because of the largest minor difference in electronegativity in non-polar, the covalent bond is also referred to as nonpolar.
The least powerful intermolecular force is the London dispersion force. When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the consequence is the London dispersion force, a transient attractive force. The term "induced dipole-induced dipole attraction" is frequently used to describe this effect.

After ovulation, the secondary oocyte is drawn from the peritoneal cavity into the uterine tube by _________
After ovulation, the secondary oocyte is drawn from the peritoneal cavity into the uterine tube by fimbriae.
Ovulation is the process by which a developed egg is released from the female ovary so that male sperm cells can fertilize it. In humans, only one egg is typically released at a time; on rare occasions, two or more may do so during the menstrual cycle. On the 14th to 16th day of the roughly 28-day menstrual cycle, the egg emerges from the ovary. The little, finger-like projections at the end of the fallopian tubes known as the fimbriae of the uterine tube, or fimbriae tube are where eggs go from the ovaries to the uterus. The ovary and fimbriae are joined.The immature ovum that forms soon after ovulation is called a secondary oocyte.Near the fibrotic end of the fallopian tube, secondary oocytes are discharged into the abdominal cavity.learn more about ovulation here:

What is a geostrophic wind? Why would you not expect to observe a geostrophic wind at the equator?
A theoretical wind known as the geostrophic wind is produced when the Coriolis effect, as well as the pressure difference forces, are balanced (PGF). It is a decent estimate for the wind reported at middle latitudes at an altitude of greater than 1 km. Given that there is no Coriolis effect near the equator, there can be no geostrophic wind.
What does "geostrophic wind" mean?
Geostrophic flow, as used in atmospheric research, is the fictitious wind that would emerge from a precise balancing act between the Coriolis effect and the pressure difference forces. The term "geostrophic equilibrium" or "geostrophic balance" refers to this situation (also known as geostrophy). Parallel to the isobars is where the geostrophic wind is pointed. In nature, this equilibrium seldom occurs perfectly. Because of these factors, the genuine wind and geostrophic wind nearly never match up.
The location of geostrophic winds:
At elevations exceeding 1000 meters (3300 feet), geostrophic wind can be found. With the use of weather balloons, the geostrophic wind velocity may be calculated. At heights up to 100 meters, the ground surface has a significant impact on winds.

Calcium reabsorption by the kidneys is promoted by the hormone parathyroid hormone.
What is parathyroid hormone?The parathyroid glands emit a peptide hormone known as parathyroid hormone, sometimes known as parathormone or parathyrin, which regulates the serum calcium content through acting on the gut, kidney, and bone.One or more of the parathyroid glands are hyperactive in primary hyperparathyroidism. The gland thus produces an excess of parathyroid hormone (PTH). Too much PTH raises calcium levels in the blood, which can result in health issues like kidney stones and bone weakening.The following processes are stimulated by the parathyroid hormone: bones' release of calcium into the blood. The intestines' absorption of calcium from meals. kidneys' preservation of calcium.Hypoparathyroidism is a condition in which parathyroid hormone secretion or activity is low.

What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis. Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds. The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light. The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution. The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: https://brainly.com/question/18316109

Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks. what is the principle reason for this?
Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks because the extrusive magma cools quickly so the mineral grains do not have time to grow.
When lava comes out of a volcano and solidifies into extrusive igneous rock, the rock cools very quickly. Crystals inside solid volcanic rocks are small because they do not have much time to form until the rock cools all the way, which stops the crystal growth. Magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.
