B. Gases dont have a fixed shape:solids do
C. Gases have particles that are closer together than thoes in a solid
D. Gases partical have less energy than solid paeticals.
Answer:
B: Gases dont have fixed shape, solids do
Explanation:
A is false because gases and solids can be both made up of atoms and also molecules
B is true because gases do not have definite shape or volume, while solids have definite shape and volume
C is false because particles of a gas are farther apart under similar pressure, volume and temperature as particles of a solid
D is false because gases have more energy than solid particles under similar pressure, volume and temperature due to their movement they are constantly transfering energy from one particle to another as they move
Answer:
Explanation:A: the atoms in a gas move at high speeds

Glycogen synthetase kinase 3 beta is a protein kinase that has been implicated in many types of cancer. Depending on the cell type, the gene for glycogen synthetase kinase 3 beta (GSK38) can act ether as an oncogene or as a tumor suppressor. Which of the following best predicts how GSK 98 mutations can lead to the development of cancer? A Cells with inactive GSK 38 fail to trigger apoptosis. B Cells with inactive GSK 38 fail to proceed past the G2/M checkpoint. с Cells with overactive GSK 98 are more likely to repair DNA damage. Cells with overactive GSK 38 have longer cell cycles.
Answer:
A Cells with inactive GSK 38 fail to trigger apoptosis
Explanation:
Apoptosis is defined as the process of programmed death cell. Tumor cells are capable of evading apoptosis, thereby leading to uncontrolled cell proliferation. Glycogen synthase kinase 3 (GSK-3) is a protein kinase that phosphorylates serine and threonine amino acid residues on different substrates, thus activating different signaling pathways and having different biological functions. The GSK-3-mediated phosphorylation on different substrates may lead to the activation or inactivation of apoptosis depending on the cell type. Thus, GSK-3 has a dual activity and functions as a tumor suppressor and oncoprotein.

Which type of feather gives the bird its color?
down
barb
contour
flight
it contour
I hope it work
Contour type of feather gives the bird its color. Therefore, the correct option is C.
The outer feathers that give a bird its color and general appearance are known as contour feathers. The barbs on the branches that make up the central shaft of these feathers join to form a strong, streamlined structure. The barbs have their own little branches, known as barbules, which contain pigments that help give the bird its color.
The diverse colors and patterns seen on many bird species are determined by the arrangement and color of pigments in the barbules of contour feathers. Therefore, contour feathers are important in determining a bird's color.
Therefore, the correct option is C.

Harassment, Corruption, and Unfair treatment of Workers
Explanation:
Business Entrepreneurship EDG 2021
Harassment, Corruption, and Unfair treatment of Workers.
What are ethical issues?When a particular action, scenario, or judgment conflicts with the moral standards of a society, there is an ethical problem. Since any of their actions could be questioned in terms of ethics, both people and companies could be implicated in these disputes.
These problems can arise in a person's interactions with other people or in their interactions with organizations, and the same is true for organizations.
These disputes can occasionally be legally risky since certain potential solutions may go against the letter of the law. In other cases, the problem might not have legal repercussions, but it might cause a backlash from outside parties.
Therefore, Harassment, Corruption, and Unfair treatment of Workers.

How are the inner and outer planets different? Use an example to support your answer.
ʕ •ᴥ•ʔ *Rawr*
Answer:
THE INNER PLANETS
Mercury, Venus, Earth and Mars
THE OUTER PLANETS
Jupiter, Saturn, Uranus and Neptune
Small size
Earth is the largest of the Inner Planets, with a diameter of 12,756 km (7,926 miles). Mercury is the smallest with a diameter of 4,878 km (3,031 miles)
Huge!
Jupiter, the largest planet, has a diameter of 142,984 km (88,846 miles). Neptune is the smallest of the Outer Planets with a diameter of 49,532 km (30,779 miles)
Have solid surfaces and thin/no atmospheres
In theory, it would be possible to stand on each of the Inner Planets, although you would only survive on Earth.
Balls of gas with no surface
Most of the Outer Planets are made of gas. It is likely that they have a much smaller solid or liquid centre. It would be impossible to stand on any of the Outer Planets.
Greater Density
The size and composition of the planets is caused by the density of the elements that make up the planets. The elements in the Inner Planets are more closely packed together, causing them to be smaller and solid.
Smaller Density
Despite being larger, the elements that make up the Outer Planets are less densely packed together causing them to be quite light for their size.
Varied atmospheres
The contents of the atmospheres of the Inner Planets varies from planet to planet. Mercury has no atmosphere although Sodium and Helium can be detected above the surface. Venus' atmosphere is mostly Carbon Dioxide with a very small amount of Nitrogen. Earth's atmosphere is mostly Nitrogen with a smaller amount of Oxygen and even smaller amounts of other gases. Mars has a similar composition of carbon dioxide and nitrogen as Venus although has a much thinner atmosphere.
Similar atmospheres
The atmospheres of the Outer Planets consist mostly of Hydrogen and Helium, with Methane also being present in the atmospheres of Uranus and Neptune. Other gases are present although in much smaller quantities.
Known by the ancients
The existence of the Inner Planets has been known about for thousands of years. The earliest astronomers didn't know that the four objects (including Earth) were planets, but they knew they existed.
Not known by the ancients
Of the Outer Planets, only Jupiter and Saturn were observed by ancient astronomers. The existence of Uranus and Neptune was not known until relatively recently. Uranus was discovered in 1781 and Neptune in 1846.
Spin slowly
Compared to the much larger Outer Planets, the Inner Planets spin quite slowly. Earth spins the quickest, taking 23 hours and 56 minutes to spin on its axis. Venus takes 243 days to spin on its axis, spinning in an opposite direction to the other planets.
Spin quickly
All of the Outer Planets spin quicker than the Inner Planets. Uranus spins slowest, taking 17 hours and 14 minutes to spin on its axis. Jupiter takes only 9 hours and 55 minutes to spin on its axis. This rapid rotation causes Jupiter and Saturn to appear squashed, wider across the equator than from top to bottom.
Orbit the Sun quickly
Because they are quite close to the Sun, the Inner Planets complete an orbit quickly. Mercury takes only 88 days to orbit the Sun. Mars takes 687 days.
Orbit the Sun slowly
The Outer Planets orbit the Sun from millions of miles and have a much greater distance to cover to complete an orbit, so take much longer to do so. Jupiter takes almost 12 years to complete an orbit and Neptune takes over 164 years.
Few Moons
Only Earth and Mars have moons orbiting them. One moon orbits Earth and two small moons orbit Mars.
Lots of Moons
All of the Outer Planets have many moons orbiting them. There are 63 moons known to orbit Jupiter, 60 orbiting Saturn, 27 orbiting Uranus and 13 orbiting Neptune.
No rings
None of the Inner Planets have rings orbiting them
Rings
All of the Outer Planets have rings orbiting them. The rings are thin discs of dust and rocks possibly caused by moons being broken up or not being completely formed while orbiting the planet. Saturn has the most visible ring system of any of the planets.
Multiple space craft visitors
Due to being close to Earth, there have been several missions to the other Inner Planets, especially to Mars and Venus. Mercury has been visited by two spacecrafts.
All Outer Planets visited by one space craft
There have been multiple visits to Jupiter and Saturn, but Uranus and Neptune have only been visited once. This was by Voyager 2 (which also visited Jupiter and Saturn).

A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?
A. He should only grow one plant in each group.
B. He should only change the wavelength of light for each group.
C. He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.
D. There is nothing wrong with the experiment.
Answer:
The correct answer is - option B. he should only change the wavelength of light for each group.
Explanation:
In any experiment or research, there should be only one variable that needs to change to see the effect of that variable on the dependent variable and other variables should be constant so there no other variables could influence the result of the experiment.
In this experiment, there is two variable are manipulated that are the different wavelength of light which is desired variable or independent variable in this experiment but CO2 level also changes in each group which should be constant but now it affects the experiment.
