Answer:
c
Explanation:
the environment is changing from ocean to dry land
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
Answer:
This question lacks options, however, it can be answered based on general understanding of forest layers.
The difference in photosynthetic rate is as a result of the amount of sunlight received by plants in the canopy and the forest floor.
Explanation:
Canopy of a forest refers to the collection of the crowns of trees found above the ground layer of a forest while the forest floor is the ground level of the forest. Plants that grow in the canopy are directly exposed to sunlight and receives most of the light from the sun while plants that grow in the forest floor are least exposed to sunlight as the crowns of the plants in the canopy covers/masks them.
Based on this, the rate at which the plants in the canopy layer photosynthesize will he higher than that of the plants in the forest floor because the amount of sunlight is a determinant of the photosynthetic rate.
<h3><u>Answer</u>;</h3>
Yes females can survive without Males
<h3><u>Explanation</u>;</h3>
- The Komodo dragon can can reproduce sexually or asexually depending on their environmental conditions. At most zoos, females live alone and are kept separate from other dragons.
- <em><u>The females Komondo dragons can produce babies without fertilization by a male. This process is called parthenogenesis or a virgin conception.</u></em>
