Which fossil fuel produces the highest levels of most air pollutants? *

Answer:

BRAINLIEST PLEASE!!!

A = Smooth Endoplasmic Reticulum

B = Vacuole

C = Mitochondria (Plural)

D = Nucleolus

E = Cell Wall

Explanation:

This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.

When we rewrite the given in a simpler unit we have 7.9 ms-1.

By looking at the units of the quantities involved, dimensional analysis is a technique for determining whether a physical equation or formula is right. The essential tenet of dimensional analysis is that the quantities being multiplied or divided in the equation must have units that are equal to the units of the final result.

We know that we have to apply the principles that apply to dimensional analysis in the question and we have that;

m^2.s/m.s^2

= ms-1

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.

b) has leaves that are 8 -10 cm long

Answer:

I would say around the 11th or 12th hour

Explanation:

seeing as the question calls for ALL of earth's history compressed into 12 hours the timeline should be similar to this: Earth was born at midnight, at around 2-3 AM land masses form, Right after that, life begins, For around 8 hours (11 PM) life is confined in water, right after that we have plants, 22 minutes later we have dinosaurs, 22 minutes later we have mammals, 5 minutes later dinosaurs are extinct, 6 minutes later we have people. So it's most likely the 12th hour. I hope this helps.

In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.

Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.

Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

1. The four main categories of stars are:

2. In general, O-type stars are the largest and most luminous, while M-type stars are the smallest and least luminous. B-type and A-type stars fall in between these two extremes in terms of size, brightness, and temperature. However, there is a lot of variation within each of these categories, and there is not a hard and fast rule for how these characteristics relate to one another. The size, brightness, and temperature of a star depend on a variety of factors, including its mass, age, and composition.

1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.

2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.

3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.
