can solute particles pass through the membrane of a semipermeable membrane?
Answer:
No.
Explanation:
No, solute molecules are larger in comparison to solvents, so they cannot pass through the semi-permeable membrane.
Answer:
Nope Nope Nope, They cannot pass through it
Explanation:
Osmosis describes the diffusion of the solvent through a semipermeable membrane. The driving force of the solvent shift is the concentration difference of solutes in the solutions separated by the semipermeable membrane. In contrast to solvent, solutes cannot pass this barrier.

5. What muscle is below the deltoid and is attached to the ulnar process? How many heads does this muscle have?
Answer:
What muscle is below the deltoid and is attached to the ulnar process? How many heads does this muscle have?
Explanation:
Triceps is the muscle that is responsible for the extension of elbow joint and also contribute to extension of shoulder joint. This muscle have three origin, that's why the name triceps. The triceps muscle has three heads which are:
A. The long head originates from the infraglenoid tubercle of scapula.
B. The lateral head originates from above the radial Grove in humerus.
C. The medial head originates form below the radial Grove in humerus.
These heads meet to form the body of triceps which gets inserted as triceps tendon in the olecranon process of ulna just behind the elbow. The contraction of this muscle causes the extension of the elbow joint.
Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.
What is Deltoid muscle?The muscle known as the triceps is in charge of extending the elbow joint and helping to extend the shoulder joint. The name triceps refers to the fact that this muscle has three origins.
The scapula's infraglenoid tubercle is the source of the long head. In the humerus, the lateral head develops from above the radial Grove. In the humerus, the medial head develops from below the radial grove.
The triceps body is formed when these heads come together, and it is placed as the triceps tendon in the ulna's olecranon process, right beyond the elbow. The elbow joint extends as a result of this muscle contracting.
Therefore, Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.

Explanation:
The bacteria normally grow in high temperature condition. So, the correct option is D.
What is Bacteria?Bacteria are defined as tiny, single-celled organisms that are millions of different types of bacteria. Many can be found in and on the body and are beneficial to us. Bacteria lack a membrane-bound nucleus and other internal structures, so they are classified as unicellular life-forms called prokaryotes.
The bacteria in our bodies help break down the food we eat, provide us with nutrients and neutralize toxins that play an essential role in preventing infection by protecting colonized surfaces from invading pathogens.
Thus, the bacteria normally grow in high temperature condition. So, the correct option is D.

what is the primary pigment that makes leaves green in land plants?
Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.
What is chlorophyll?It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.
During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.
It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.
Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.

ATP is the energy currency of the cell and it is required almost everywhere. 4 cellular activities that would require the energy of ATP will be cellular respiration, ion transport, muscle contraction, nerve impulse.
What is the role of ATP ?The role of ATP is providing energy where it gets hydrolysed into ADP along with the phosphate ion where the reaction provides energy and this reaction brings about energy in the activity.
The cellular activities are the activities that take place inside the cell and various activities that will link to them in order to perform various functions. DNA synthesis, biochemical reactions, cellular respiration, cellular activities all takes place with the help of ATP.

Pollution
The stream runoff from small watersheds feeds into larger streams and rivers. The sun evaporates some water back into the air as it inflows into streams, rivers, and oceans.Wetlands' highly developed root systems hold the soil in place and filter pollutants, naturally improving water quality (including water that is eventually used for drinking).Contaminants present in these surface waters can contribute to contamination of the groundwater system. Some wells rely on artificial recharge to increase the amount of water infiltrating an aquifer, often using water from storm runoff, irrigation, industrial processes, or treated sewage.Heavy metals and other contaminants can accumulate in seafood, making it harmful for humans to consume. Microplastics can be ingested by fish and other species that filter their food out of the water.The salinity of the ocean varies from place to place, especially at the surface. Much of the ocean has salinity between 34 ppt and 36 ppt, but there are places that tend to be higher or lower.How is pollution caused?
Pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes, and wildfires.
