Answer:
a virus, because it requires a host cell to reproduce
Explanation:
a bacterium, because it is contagious a fungus, because it infects livestock a protist, because it is microscopic a virus, because it requires a host cell to reproduceThe correct answer would be a virus because a virus is the only microbe that cannot reproduce on its own without a host. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.
In lytic cycle, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.
In lysogenic cycle, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.

Explanation:
1. Which of the following is a characteristic associated with an organism's niche but not with its habitat?
a. climate
b. soil quality
c. place in the food web
d. location within the ecosystem
A characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In a more simple sense, habitat may also be characterized as an area where the basic demands of an organism are fulfilled like food, space, and mating partner.
According to the context of this question, a pace in the food web determines the position and the type of food that an organism naturally eat or consume. As it connects the organisms with the source of energy.
But in reality, it does not describe any characteristics of the habitat to which a particular organism belongs. This is because the food web is the pictorial representation of organisms on the basis of their food habit and nature.
Therefore, a characteristic that is associated with an organism's niche but not with its habitat is the place in the food web. Thus, the correct option for this question is C.

B. Plants in the desert would have a decreased number of stomata compared to rainforest plants.
C. Plants in the desert would have an increased number of mitochondria compared to rainforest plants.
D. Plants in the desert would have a decreased number of stomata compared to rainforest plants.
Answer:
A.Plants in the desert would have an increased number of stomata compared to rainforest plants.
Explanation:Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.
Which description identifies a factor that influences the flow of water through the plasma membrane of a human cell?
A. The size of the phospholipids and proteins composing the plasma membrane
B.the concentration of solutes on either side of the plasma membrane
C.the presence or absence of a cell wall outside the plasma membrane
D.the number of contractile vacuoles on the surface of the plasma membrane
Answer:
A
Explanation:
Osmosis refers to the movement of water molecules across a selectively permeable membrane. During this process, water molecules move from an area of high concentration to an area of lower concentration.
A factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).Osmosis is a type of passive transport mechanism that does not require energy to occur.During osmosis, water diffuses through a selectively permeable membrane from an area of high water concentration to an area of lower water concentration.In an isotonic cell, the concentration of solutes and water molecules is equal on both sides of the plasma membrane.In conclusion, a factor that influences the flow of water through the plasma membrane of a human cell is the concentration of solutes on either side of the plasma membrane (Option B).

Lucy and Jim have been married for 5 years and have decided they would like to try to have a child. However, a rare genetic disorder runs in both or their families, so they decide to go to a genetic counselor to determine the chances that their future child will be affected. The disease achondrogenesis 1a affects the ability of proteins necessary for bone and cartilage development to be modified and packaged properly after leaving the endoplasmic reticulum. The results are devastating. Individuals with this disorder are often stillborn or die soon after birth from respiratory failure. Fortunately, after doing a genetic screening, the genetic counselor determined that while Jim is a carrier for this autosomal recessive disorder, Lucy is not. Therefore, if they do have a child it is unlikely that their child will be affected. Which organelle has been compromised
Answer:
The Golgi complex is compromised
Explanation:
The Golgi complex helps in the process of synthesis and packaging of proteins and lipids, especially those proteins that are for exportation. The organelle´s function is to manage the recently synthesized proteins, to transform them, and to export them to other places.
Different proteins are synthesized in the endoplasmic reticulum and sent to the Golgi complex in vesicles, where it happens the final association of carbohydrates with proteins. Finally, protein is transported from the Golgi complex to its final destiny. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
By being affected by the achondrogenesis 1a, the Golgi complex loses its functions and is incapable of finishing the protein synthesis and transport process, affecting other cells and their functions.
describe how the ancestors of whales moved from the land to the sea.
Answer:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down.
Explanation:
Are tyere any mammalian cells that would be a good source for dividing cells?
Answer:
Explanation:
This question appear wrong. Cells do not divide other cells as cells have the ability to undergo individual cell division as seen in cell cycle. However, there are some factors that could lead to increased cell division; factors such as cancer and viral infection can lead to increased division of certain cell types.
There is also a cell organelle present in mammalian cells that facilitates the division of a cell - this organelle is known as centriole. Centrioles do this by assisting in the separation of chromosomes during the mitotic phase of the cell cycle.

explain how the structure of a cell´s membrane is related to its function.
Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
The structure of cell membrane helps in being selectively permeable that play a major role in regulating the entry and exit of molecules into and out of the cell.
The cell membrane is a biological membrane that makes the barrier between the interior of all cells and the outside environment. It is composed of a phospholipid bilayer with embedded proteins.
Due to phospholipid bilayer that has hydrophilic heads toward outside and intercellular matrix and hydrophobic tails in the middle, it is selectively permeable to ions and organic molecules:
It forms a physical barrier between the cell and the external environmentselected necessary molecules to pass through itregulates the entry and exit of molecules into and out of the cell. permits the entry of vital molecules like water, oxygen and amino acids, glucose into the cellthese molecules are crucial for various life processesmetabolic waste products are expelled through the cell membrane.it provides signals from one cell to another.Thus, the major function of cell membrane is due to its structure.

Explain how bacteria become resistance to
antibiotics, supporting Darwin's theory..
Answer:
They adapt over time to the antibiotics.
Explanation:
Because of Darwin's theory of natural selection, the bacteria that are resistant to antibiotics will multiply whereas the ones that don't survive will die off. Over time, the species will only consist of those bacteria that are resistant, because they are the ones that survived. Hope this helps!
Answer:
Since bacteria reproduce at a very fast rate, they can also develop mutations; creating new strains. Some bacteria might become resistant to certain antibiotics because of these mutations. The evolution of the bacteria supports Darwin's theory of evolution !
