Answer:
These features correspond to the plant kingdom.
Explanation:
Plants are non-motile autotrophic organisms, they can synthesize chemical energy by using sunlight (trough a process named photosynthesis). Moreover, plants play a critical role in the ecosystems since these organisms produce oxygen when they photosynthesize.
Answer:
The scientific notation is 4.0075 x 10^7 m
Explanation:
In this case, the Earth's circumference at the equator which is equal to 40,075,017 m can be expressed in terms of scientific notation by multiplying it to a factor of 10.
Answer:
The cell wall
Explanation:
The cell wall exists to protect the cell, maintain its shape and regulate water uptake. The cell wall is much thicker than the cell membrane, providing an extra layer of protection. In plants, the cell wall is made of fibres of the polysaccharide cellulose, which is a structural carbohydrate.
This gives organisms such as plants much more structure - e.g. they can stand upright without the need for bones. However, they lack the same flexibility that animal cells have.
Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.
