Listing the structures in order from smallest to largest follows this sequence ( A ) ; Gene right arrow DNA right arrow Chromosome right arrow Nucleus
Gene is the basic unit of heredity in animals, they are made up of DNA strands, while chromosomes ( thread like structures ) are positioned inside the Nucleus of ( plant and animal cells ).
Chromosomes are comprised of proteins and single molecule DNA that are passed from parents to its offspring.
Hence we can conclude that the flowchart that lists the structures in order from smallest to largest follows this sequence ( A ) ; Gene right arrow DNA right arrow Chromosome right arrow Nucleus.

Chloroplasts are found in lettuce cells but not mouse cells.
A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells.
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells.

Answer:
The root of a huge tree causes cracks in a rocky surface.---> biological Weathering.
Part of a cliff breaks and falls due to waves.----> mechanical weathering
Acid rain reacts with calcite present in limestone---> chemical weathering
Explanation:
The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved. Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands. Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.
Here's the matching of the scenarios with the types of weathering:
1. The root of a huge tree causes cracks in a rocky surface - Biological Weathering
2. Part of a cliff breaks and falls due to waves - Mechanical Weathering
3. Acid rain reacts with calcite present in limestone - Chemical Weathering
Biological Weathering: In this scenario, the root of a huge tree causes cracks in a rocky surface. Biological weathering refers to the breakdown of rocks caused by the activities of living organisms. The roots of the tree can exert pressure on the rocky surface as they grow, causing cracks and eventually breaking apart the rock.
Mechanical Weathering: Part of a cliff breaks and falls due to waves. Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. In this case, the force of the waves pounding against the cliff causes pieces of the rock to break off and fall.
Chemical Weathering: Acid rain reacts with calcite present in limestone. Chemical weathering involves the breakdown of rocks through chemical reactions. Acid rain, which is rainwater with a low pH due to the presence of acidic compounds, reacts with the calcite (a mineral in limestone) and causes it to dissolve, leading to the erosion and weakening of the limestone.
Each type of weathering plays a role in shaping the Earth's surface over time, and they often work together to break down rocks and minerals into smaller particles.

Answer;
Symbiosis
Symbiosis is the term that includes Commensalism , mutualism and parasitism.
Explanation;
Parasitism is a symbiotic relationship does one organism benefit while the other organism is harmed.
Commensalism is a symbiotic relationship between two species in which one benefits, and other is neither harmed nor helped.
Mutualism on the other hand is where both organisms involved from each other. Example is the relationship between an Oxpecker and the rhinoceros or Zebra.
Explanation:
If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.
Answer: Vasodilator
Explanation:
If a person is suffering high blood pressure then the pressure inside the blood vessels increases because of vasoconstriction. Vasoconstriction is a condition in which the diameter of the blood vessels decreases and blood pressure increases.
In this case, vasodilators are given to the patients which helps in increasing the diameter of the blood vessels so that the pressure inside the blood vessels decreases.
