Oxygen is taken into cells by the process of simple DIFFUSION.
Simple diffusion is a cellular process by which small molecules (e.g., oxygen and carbon dioxide) pass across the plasma membrane and thus can enter and leave the cell.Simple diffusion always occurs in favor of a concentration gradient, i.e., from a region of high concentration to a region of low concentration.For example, oxygen (O2) molecules move from a region of high concentration in the lungs to a region of low concentration in the blood.This process (diffusion) does not require energy to move molecules across biological membranes.In conclusion, oxygen is taken into cells by the process of simple DIFFUSION.

A student kicks a soccer ball three times. Another student records the distance, the amount of time the ball travels, and the average speed in the table shown below. How many seconds did it take for the ball to travel 30 m during Kick 3?
F. 0.5 s
G. 1.0 s
H. 1.5 s
J. 2.0 s
Answer:
2/j
Explanation:
formula: average speed= total distance/total time
15=30/total time
30/15= 2
Hope this helped and good luck!!!
It would take 1 second for the ball to travel 30 m during Kick 3
SpeedSpeed is the ratio of total distance travelled to total time taken. It is measured in meters per second. The formula for speed is given by the equation:
Speed = distance / time
From the question, average speed = 30 m/s, hence:
Average speed = distance / time
30 = 30 / time
time = 1 second
It would take 1 second for the ball to travel 30 m during Kick 3.

Which evidence supports the idea that life on Earth has continually evolved
Answer:
Fossils are the remains of long-dead organisms, preserved in rock. Because rocks are laid down in layers, one on top of the other, the fossil record is generally set out in date order: the oldest fossils are at the bottom. Running through the fossil record makes it clear that life has changed over time.

What are the FIVE ways an object's motion can change?
Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.
Explanation: please can I get brainliest
Motion is defined as the phenomena where an object moves from one point to another. Usually, a force has to act on the object for it to be in a state of motion.
Mathematically, motion has to do with:

The picture shows the process of asexual reproduction in hydra. According to the illustration, all offspring are
-
ning
-19
A) genetically varied.
B)
genetically identical to the parent.
slightly similar to the parent.
D)
genetically very different from the parent
Answer:
There is no illustration, but the question can be answered based on general understanding of reproduction. The answer is:
B) genetically identical to the parent.
Explanation:
Reproduction, which is the process by which organisms produce their offsprings, can be done in two major ways namely: sexually and asexually. The asexual reproduction involves only one parent that undergoes division to form two daughter cells.
Since there is no exchange of genetic material between two parties as it involves only a single organism, the offsprings will be GENETICALLY IDENTICAL to the parent cell. This is the case of Hydra in this question that underwent asexual reproduction. All of the offsprings of this mode of reproduction will be GENETICALLY IDENTICAL i.e. have the same genetic composition as their parent.

Which description distinguishes eukaryotes from prokaryotes
Answer:
Explanation:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Prokaryotes only contain a single circular chromosome and lack a nucleus and membrane-bound organelles. In contrast, eukaryotes have numerous linear chromosomes and a nucleus.
Organisms called eukaryotes have intricate cellular structures. Their cells are distinguished by the presence of a genuine nucleus, which contains the DNA that serves as the genetic code. The nuclear envelope, a double membrane that encloses the nucleus, is made up of numerous organelles including the Golgi apparatus, endoplasmic reticulum, and mitochondria. These organelles are in charge of carrying out numerous metabolic processes and carrying out specialised tasks required for the survival of the cell. On the other hand, prokaryotes are straightforward organisms devoid of a nucleus and organelles that are bound to membranes. Their cells have a single nucleoid, a circular fragment of DNA that floats freely in the cytoplasm and gives them some control over their genetic makeup.

Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.
