Answer:
Talons
Explanation:
Talons are an owl's primary weapon for catching its prey. When an owl catches its prey, two of its talons go forward and two go backwards to ensure that when the prey is caught, it cannot escape.

Cells vary in _____ and _____.
A cell carries out _____.
The __________ allows substances to move in and out of the cell.
Answer:
Explanation:
Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.
20 POINTS, SOMEONE PLEASE DO THIS. The questions are;
1. State 6 differences between mitosis and meiosis. It could be differences when it comes to the process itself and also molecular differences.
2) Mention 2 differences between sexual and asexual reproduction.
3) Please state the stages of the cell cycle and what is occurring in each state.
Answer:
this might help
Explanation:
Mitosis
Meiosis
Where it occurs
Occurs in all organisms, except viruses
Only occurs in animals, plants, and fungi
Cells it produces
Creates body/somatic cells
Creates germ/sex cells
Number of cell divisions
One cell division ( 4 stages total)
Two cell divisions (8 stages total)
Prophase length
Prophase is short
Prophase I is longer
Recombination/crossing over
No recombination/crossing over in prophase
Recombination/crossing over of chromosomes during prophase I
Metaphase
During metaphase, individual chromosomes line up on cell’s equator
During metaphase I, pairs of chromosomes line up on cell’s equator
Anaphase
During anaphase, sister chromatids move to opposite ends of the cell
During anaphase I, sister chromatids move together to the same cell pole.
During anaphase II, sister chromatids are separated to opposite ends of the cell
Number of cells created
End result: two daughter cells
End result: four daughter cells
Ploidy
Creates diploid daughter cells
Creates haploid daughter cells
Genetics
Daughter cells are genetically identical
Daughter cells are genetically different
What happens to the air pressure in an area if the air temperature increases?
A) The air pressure will increase because the air particles are packed together.
B) The air pressure will decrease because the air particles are spread out.
C) The air pressure will remain the same because temperature does not affect the air particles.
D) The air pressure will remain the same because the hot air will travel to different areas.

The Earth’s orbit around the sun is perfectly circular
True
False
Answer: False
Explanation: A perfectly circular orbit would mean that the earth is always the same distance from the sun
Answer:
Earth's orbit is not a perfect circle
Explanation:
Earth's orbit is not a perfect circle. It is elliptical, or slightly oval-shaped. This means there is one point in the orbit where Earth is closest to the Sun, and another where Earth is farthest from the Sun. The closest point occurs in early January, and the far point happens in early July
The closer to the sun a planet is, the hotter it is.
True
False
Answer:
true

Answer:
Only first 1 requires energy, rest all are passive transports!!Explanation:
First one:Here the molecules are moving from region of low concentration to high concentration, so as it is an uphill transport also known as Active transport. So active transport requires the ATP to be carried out.
Second one:This is the normal passive transport of hydrophobic or lipid soluble substances. So as normal passive transport requires no energy but a concentration gradient. So it doesn't require the ATP to be carried out.
Third one:This is a transport system of protozoans like Amoeba which form a pseudopodia process around the food, and then engulf the substances which then is surrounded by vacoule for digestion to take place. It also doesn't require energy.
Fourth one:This is an example of bulk transport mechanism where large big molecules move from higher concentration to their lower concentration through special membrane proteins and then their utilisation takes place. This is also known as Endocytosis. This also doesn't require energy to be carried out.
How many Oxygen atoms are in 12CO2 ?
So, from the name, we can say that carbon dioxide has two oxygen atoms. Alternatively, we can use the chemical formula of the molecule. Carbon dioxide has a chemical formula of CO2 .
There are twenty-four atoms of oxygen in 12CO₂.
What is oxygen and carbon dioxide?Oxygen is a gas that is present in the atmosphere, to mix with air. Oxygen is the most needed gas. It is used by living beings in breathing. Oxygen is needed for the breakdown of food molecules in living organisms. Oxygen is taken by hemoglobin present in the blood. This process is called respiration.
Carbon dioxide is also a gas that is present in the atmosphere. This gas increases the warmth of the earth. These are greenhouse gases. This is present 0.03 %.
CO₂ has two molecules of oxygen, as written here.
Given, 12CO₂
The 12 moles are multiplied by 2 moles of oxygen, which is equal to 24 moles total.
12 x 2 = 24
Therefore, there are 24 atoms of oxygen in 12CO₂.

Why is it harder for evaporation to occur when the air pressure is high?
A) Evaporation only occurs when there is no air pressure.
B) The air particles are heavier with little ability to rise.
C) The air particles are packed together with little space for water vapor.
D) The air particles are spread out with plenty of empty spaces for water vapor.
Air pressure has a few effects on evaporation. If the air pressure is high on the surface of a body of water, the water will not evaporate quickly. The pressure on the water makes it very difficult for the water to disperse as a vapor into the atmosphere. Air pressure is the force of the surrounding air that is acting on the surface of the water. Greater air pressure means greater force per unit area. This pressure is forced on evaporating water molecules, so greater air pressure means that the water molecules will exert more energy to evaporate. That being said, you could say the air particles are heavier and weighing down on the water. I hope this helps! Have a great day. :)

if a ball goes at 135 mph,how fast will it travel over a year?
Answer: I will travel fast in a year I guess
Explanation:
Answer:
The optimum number is a 1:1.5 ratio between clubhead speed and ball speed. ... In other words, at 100 mph of clubhead speed, a solid blow will send the ball at 150 mph off the face of a legal driver. The lower the ratio, the poorer the quality of the strike and the more inefficient the impact.
