In order for gas to leave a planet it needs to be hot enough and to overcome the planets gravity. The outer planets are colder and are very big compared to earth.

Scrat [10]

Answer:

They waited before crossing a busy street

Explanation:

Assume the graph looks like the one below.

It shows that, from Point B to C, the distance they were from home did not change.  They had stopped.

A possible interpretation is that they waited before crossing a busy street.

If they had begun accelerating, BC would have been steeper than AB.

If they had slowed their walk, BC would still point up. However, its slope would be less than that of AB.

If they had returned home, BC would point down and to the right.

A skateboarder has an initial velocity of 3 m/s West and comes to a stop in 2 seconds. What is the skateboarder's
ArbitrLikvidat [17]

Answer:

FV- 0 m/s

IV- 3 m/s

t- 2 sec

A= FV-IV/t

A= 0-3/2

a= -1.5 m/s²

Explanation:

FV- Final Velocity -> m/s

IV- Initial Velocity -> m/s

A- Acceleration -> m/s²

t- time -> seconds

What do brittle stars eat
Goshia [24]

Answer:

Brittle stars eat decaying plant matter (they are detrivores) and plankton, but can also kill small animals to eat as well.

What chromosomes are found in body cells but not sex cells?
Leni [432]
None, egg cells don't have chromosomes. No, sex cells do have chromosomes. meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

The net energy yield from this pathway, where glucose is broken down through several steps forming pyruvate, is ________ molecul
stepan [7]

Answer:

2 molecules of ATP and 2 molecules of NADH

Explanation:

Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.

Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.

In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase

All the DHAP molecules get converted to G-3-P in order to enter the next phase.

In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.

Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.
