Since forces cause a change in motion or state of a body, friction is a force which opposes motion of an object over another.
What is frictional force?Frictional force or friction is the force that opposes the relative motion of one object over another at their surface of contact.
The two types of friction are:
static friction andkinetic frictionRough surfaces experience the greatest friction while smooty surfaces experience the least friction.
Hence, friction can be reduced by lubrication or polishing.
Based on the property of forces and friction:
Force is defined as a push or pull that starts, stops or changes the direction of a moving object.Friction is a force that opposes motion between two surfaces sticking or touching together.A sandy floor has the greatest frictional force among these surface.Friction is a force that opposes motion. It acts in the opposite direction of a moving object. Friction is a force that occurs when surfaces touch each other.

What is the name of the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle?
Answer:
It is called the Centrosome
Explanation:
The Centrosome is known as the main microtubule organizing center of animal cells, the Centrosome participates in the organization of the microtubule network within a cell. It's formed with two centrioles surrounded by a matrix of proteins called pericentriolar material.
The cell cycle includes various phases. The microtubule-organizing center found in animal cells is present during all phases of the cell cycle are centrosomes.
What is a centrosome?A centrosome is a cellular organelle which is involved in the process of cell division.
Before cell division, the centrosome duplicates, as division begins, the two centrosomes starts moving to opposite ends of the cell.
It is the main microtubule-organizing center (MTOC) of animal cell. It is also a regulator of cell cycle progression.
Thus, the centrosome is the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle.

Your friend tells you that sunlight breaks rocks into small pieces. using what you learned from the video, revise this statement, explaining how the process is more complicated than that
The process is more complicated than that because the cycle of expansion and contraction brings about the weathering process.
What is Weathering?This is the process in which rocks are broken down into smaller fragments or particles.
Sunlight heats the rocks and causes expansion which cools down during the night. This cycle of expansion and contraction is what disintegrate the rocks into smaller pieces.

Pls answer!!
a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.

Explanation:
ATP is the main energy-storing molecule found in all living organisms. It transports the energy necessary for all cellular metabolic activities. It is made through the process of photosynthesis using energy from sunlight, or through the process of cellular respiration in the mitochondria of a cell.
Hope this helps!!
The energy of the sun is converted into usable energy for the cell in the form of simplest form of energy a cell can use is a molecule known as adenosine triphosphate (ATP).
How is energy converted?Light energy absorbed via way of means of pigments produces high-power electrons which can be used to transform NADP+ and ADP to the compounds NADPH and ATP, trapping the power in chemical form.
Sunlight is transformed to chemical power withinside the shape of ATP (adenosine triphosphate), that's the principle energy -storing molecule in dwelling organisms.
