Answer:
Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).
Explanation:
If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.
In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.
Answer:
Areas of savanna are turning into desert.
Explanation:
The answer is two, haploid.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so each of these two haploid cells will in meiosis II produce two haploid cells. In total, meiosis results in four haploid cells.
Answer:
<h2>What is a biome?</h2>
A biome is an area classified according to the
species that live in that location . Temperature
range, soil type, and the amount of light and
water are unique to a particular place and form
the niches for specific species allowing scientists
to define the biome.
<h2>How does it relate to an Ecosystem?</h2>
<h3>Ecosystem</h3>
An ecosystem is a geographic area where plants,
animals, and other organisms, as well as weather and
landscapes, work together to form a bubble of life.
<h2>What biomes make up North America?</h2>
<h3>North American Biomes:</h3>
- Arctic & Alpine Tundra.
- Coniferous Forest (Taiga)
- Grassland (Prairie)
- Deciduous Forest.
- Desert Biome.
- Tropical Rain Forest.
- Urban Sprawl.
- Adaptations Links.

The answer is true. The reason why they should be tested or re tested is because it is essential that they should be free from any harmful microbes because this are being worn and used for the individual's safety in handling and manipulating carcinogens.
