Answer:

S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

Answer:

Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time

Sea floor spreading

Explanation:

The process responsible for creating magnetic changes along the mid-ocean ridges. Sea floor spreading entails the movement of the lithosphere over the weak and fluid asthenosphere. At the spreading center new oceanic crust is created.

The earth is surrounded by a magnetic field. Magnetic minerals in fresh magma orients in the direction of prevalent magnetic field when they begin to cool and solidify.

Due to changes in the magnetic field direction and the upwelling of new magma, the magnetic patterns in a rock changes.

Answer:

Starch is a indicator in the iodometric titration and it turns deep dark blue when iodine is present in a solution. The starch under warming condition forms amylose and amyl pectin's which combine with iodine to produce dark blue color. In absence of iodide ion starch indicator is colorless.

Explanation:

Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced. Beta-amylose combines with iodine, resulting in a dark blue color change. The iodine-starch test is a chemical reaction that is used to test for the presence of starch or for iodine. The combination of starch and iodine is intensely "blue-black". The interaction between starch and triiodide is the basis for iodometry. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I2 that is released. This absorption will cause the solution to change its color from deep blue to light yellow when titrated with standardized thiosulfate solution. This indicates the end point of the titration. Aside from their basic nutritional uses, starches are used in brewing and as thickening agents in baked goods and confections. Starch is used in paper manufacturing to increase the strength of paper and is also used in the surface sizing of paper. When starch is heated in water, various decomposition products are formed, among which is beta-amylose which forms a deep blue-black complex with iodine. The starch indicator solution must be freshly prepared since it will decompose and its sensitivity is decreased.

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.

Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.

The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Answer:

In a lipid bilayer, the hydrophilic part is the head, and the hydrophobic is the tail. This location makes sense because the plasma membrane has a barrier that has a selective permeability so it selects what goes in and what goes out of the lipid bilayer.

Answer: C

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster:  the space between atoms increases:   The motion and spacing of the particles determines the state of matter of the substance:  The end result of increased molecular motion is that the object expands and takes up more space.

Answer:

warthog

Explanation:

1. Zebra burns too many calories when its hunted

2. Warthog when times 3 times makes 15k calories

3. Wildbeast would exhaust the lion and meerkats wouldnt give it enough calories

Larger lions should hunt on warthog as from hunting these organisms they get more energy as compared to the energy required for hunting. Lions will get 12,000kcal per hunt of a warthog.

Energy flow is the flow of energy in an ecosystem through different living organisms. The flow is unidirectional i.e., it starts with the Producers and goes on to the primary consumers and further to secondary consumers in a food chain. Each level in a food chain is known as a trophic level.

Energy flow in an ecosystem follows the 10% law where, only the 10% of the energy present at the previous trophic level is transferred to the next trophic level.

In this question, larger lions needs to hunt for survival and have 15,000kcal energy to expend per day. They need to get maximum energy from hunting less than three times a day. So, by hunting on warthog they expend 5,000kcal of energy and get 12,000kcal per kill. This way they get maximum energy from hunting three warthogs, i.e., 12,000×2 = 24,000kcal from expending 10,000kcal energy.

Answer:

the correct answer is B Frame shift insertion

Explanation:

plz give me brainiest

Frameshift-insertion mutations affect the amino acid sequences.

Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.

This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.

These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.

Thus, Frameshift-insertion mutations affect the amino acid sequences.
