Firstly we have to know what is meiosis.
Meiosis is the cell division process by which a diploid (2n) mother cell divided twice to produce four haploid (n) daughter cells.
Diploid cells have paired chromosomes. For example, in human, the diploid cells contain 23 paired chromosomes, i.e., 46 chromosomes.
Haploid cells do not have paired chromosomes. In human, the haploid cells contain 23 chromosomes only.
We know, chromosomes contain DNA (Deoxyribonucleic Acid).
So, if the chromosome number is half in case of haploid cells, then obviously, they have half as much DNA.
So, the correct option is 2. They have half as much DNA.

Answer:

2. They have half as much DNA.

State one effect the reintroduction of the wolf may have on the coyote population within the Adirondacks

Masteriza [31]

Answer:

Decrease in the population of coyote occurs after the reintroduction of the wolf within the Adirondacks effect.

Explanation:

Wolves are the top predator in the ecosystem. They hate coyote and kill them and sometime eat them too. So the reintroduction of the wolf decreases the population of coyote by killing them directly and by consuming the prey and the coyote die due to hunger. Coyote feed on rabbit, snakes, deer, fruits and grasses so decrease in coyote population increases the availability of grasses and other animals for different animals.

Bioflix activity: membrane transport -- vocabulary review can you match the processes involved in membrane transport to their de

Natalka [10]

Explanation:

From the diagram with corresponding labels:

Exocytosis
Facilitated diffusion
Endocytosis
Diffusion
Active transport

Further explanation:

Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Active transport is a mediated process that requires the use of specialized membrane proteins these proteins require energy in the form of avenues and triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules.

Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane. Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

...some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle; different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells, water and targeted substances respectively.

Similarly, in exocytosis, the particles (Protein, Waste material etc.) surrounded by a phospholipid membrane. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.
