Adaptations are like mini evolutions that occur in 1 generation , the plant or animals body changes based on the environment around it. Sometimes when and organism evolves it's because of natural selection, which basically means that the organism with the best trait will survive

During periods of vigorous physical activity, a person's breathing and heart rates increase. This enables the cells of the body
Sati [7]
Activate,cells can be classified by their activity.For example fat cells are one of the least active cells and it's hard to activate them;that's why it's hard to lose weight.The least active cells are bone (aka bone marrow cells) that are never active unless there's a fracture.Cells can also be classified by the amount of water they carry and their age.So when you're doing a lot of physical activity your heart rate and breathing increases because your cells are more active.

1. state the characteristics of Chrysophytes.
GuDViN [60]

1. Chrysophytes

⇒ Unicellar

⇒ Present in water bodies with low calcium levels.

⇒ Golden yellow colour due to accessory pigment.

⇒ Cell walls made of cellulose and silica.

⇒ Free swimming.

⇒ Two unequal flagella.

2. Dinoflagellates

⇒ Dinoflagellates are essentially golden-brown, biflagellate, unicellular motile protists.

⇒ Golden brown is the primary color, but due to changes in the ratios of other pigments, it may also take on yellow, green, brown, or even blue forms.

⇒ Theca or lorica, composed of articulated and sculpted cellulose plates, is a stiff covering that typically covers cells.

⇒ One flagellum is transverse and the other is longitudinal, making the two flagella distinct (heterokont).

⇒ Mesokaryon is the name given to the big nucleus.

⇒ Chlorophyll a and chlorophyll c are found in plastids or chromatophores.

⇒ In the sea, certain dinoflagellates like Gymnodinium and Gonyaulax proliferate in vast numbers, turning the water red and resulting in the so-called "red tide."

⇒ Dinoflagellates in the ocean exhibit bioluminescence. such as Noctiluca.

3. Euglenoids

⇒ Unicellular protists called euglenoids, like the genus Euglena, are frequently found in freshwater.

⇒ The pellicle, a protein-rich cell membrane, exists in place of the cell wall.

⇒ They bear two flagella on the anterior end of the body.

⇒ A small light sensitive eye spot is present.

⇒ They can prepare their own food because they have photosynthetic pigments like chlorophyll. They act like heterotrophs when there is no light, though, by catching other tiny aquatic creatures.

⇒ They are referred regarded as the connecting link between plants and animals since they exhibit both plant and animal-like characteristics, making it difficult to categorize them.

4. Slime moulds

⇒ Chlorophyll does not exist in them.

⇒ Only the plasma membrane encloses them. The spores, however, contain cellulose cell walls.

⇒ They often reside near decomposing vegetation.

⇒ They have a diverse spectrum of coloring.

⇒ They are saprotrophic or phagotrophic feeders.

What is a system of ideas that explains many related observations and is supported by a large body of evidence acquired through
Ghella [55]

Answer:

A theory.

Explanation:

A scientific theory is the product of related observations supported by evidence acquired through scientific investigation. An example of a theory includes the theory of evolution (which explains observations in the fossil record, phylogenetic patterns observed in species, and these results have been aquired through scientific investgation and analysis of things like the genome of species, and archeaological evidence)
