Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

The endosymbiotic theory states that the mitochondria of eukaryotes are the evolutionary result of a Proto-eukaryotic cell engulfing an aerobic bacterium, which then evolved into the mitochondrion. Which characteristic of mitochondria supports this theory of development? A retention of a single layer membrane B retention of the chlorophyll pigments C retention of their own genome D retention of their own nucleus
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.

Base your answer to the question on the information below and on your knowledge of biology.
A biology student was given three unlabeled jars of pond water from the same source, each containing a different type of mobile unicellular organism: euglena, ameba, and
paramecium. The only information the student has is that the ameba and paramecium are both heterotrophs and the euglena can be either heterotrophic or autotrophic, depending
on its environment
State one way the euglena's two methods of nutrition provide a survival advantage the other unicellular organisms do not have.
No
Answer:
They can perform photosynthesis.
Explanation:
Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.
The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.

Answer:
Distance and displacement are the same in the 100-m sprint, therefore, velocity and speed are the same in the 100-m sprint.
Distance is 400 meters in the 400-m sprint, therefore Speed is not zero in the 400 M sprint.
Displacement is zero in the 400-m sprint, therefore, Velocity is zero in the 400-m sprint
Note: The question is missing some details which is given below;
A 100-meter sprint is a race using only the straight side of a racetrack. a 400-meter sprint is a race that makes one complete lap around a racetrack. why are velocity and speed the same for a 100-m sprint but not a 400-m sprint?
Explanation:
The speed of a body is the ratio of the distance covered and the time taken whereas the velocity of a body is the rate of change of displacement with time.
Distance measures the total length of space covered throughout the duration of motion, whereas displacement measures the change in a specified direction from a specific point.
In the 100 m race along a straight line, both distance and displacement = 100 m, therefore speed and velocity are the same. However, in the 400 m race, distance covered is 400 m, but the displacement is zero since the person returns to his/her starting point. Therefore, speed is not equal to zero, but velocity is equal to zero.

Some cells are specialized for
facilitated diffusion, a form of passive
transport. What sorts of structures
would these cells have more of?
Answer:
The cells specialized in passive diffusion have a greater amount of membrane structures called transport proteins.
Explanation:
Facilitated diffusion is a transmembrane transport mechanism, which consists of the passage of substances through the cell membrane by means of a transporter.This process does not require energy, as it is a passive transport, and depends on an ionic gradient or concentration.
The carriers of facilitated diffusion can be integral membrane proteins, so a cell specialized in this type of transport must have abundant transport proteins.

why blood in pulmonary artery is voilet but in pulmonary vein is scarlet?
Explanation:
hope it will help you.
Merry Christmas
Answer:
The blood in the pulmonary artery is violet because it is not oxygenated, while the blood carried by the pulmonary veins is oxygenated and its color is scarlet.
Explanation:
Under normal conditions, the arteries carry oxygenated blood, giving it a dazzling red or scarlet color, while the veins carry non-oxygenated blood —called venous blood— of a purplish and dark red color.
The only exceptions are the pulmonary arteries and veins
Pulmonary arteries carry non-oxygenated blood from the right ventricle to the lungs. They are the only arteries that carry non-oxygenated blood.Pulmonary veins carry oxygenated blood from the lungs to the left atrium, being the only veins to carry blood with oxygen.This is why in the pulmonary arteries the blood is violet, and in the pulmonary veins the blood is scarlet.

Answer:
There are two major ways that molecules can be moved across a membrane, and ... is trying to be evenly distributed everywhere, like dropping food coloring in water. ... These channels are almost always specific for either a certain molecule or a ... When a molecule moves down its concentration gradient is it participating.
When a solute particle from the region of high concentration travels towards the region containing the lower solute particle is called passive transport. It is transported easily without spending energy.
Bacteria ensures that the food molecule from the surrounding will transport through the passive transport system by the concentration gradient as molecules can get in the cell by two processes.
Concentration gradient allows the movement of food from the region of high concentration towards the region of low concentration that is in the bacterial cells.
Bacterial membrane permits the movement of food molecules across its membrane easily.
Therefore food is transported to the bacteria through passive transport.
