Answer:
Option C. It is found only in a eukaryotic cell.
Explanation:
Plasma membrane is also called cell membrane. It is found in all cells of living organisms both unicellular and multicellular. It controls the amount of nutrients and wastes entering or leaving a cell. Due to permeability, the substances are easily pass through. Plasma membrane also act as boundary of animal cell.
Answer:
c. Proteins and lipids are made on the ER membrane and put in vesicles.
a. Vesicles containing proteins and lipids fuse with the Golgi bodies.
d. The Golgi bodies tag the molecules to signal their ultimate delivery.
b. Vesicles pinched off from the cristernae carry the molecule to its location.
Explanation:
Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.
Answer:
Both the food chain and food web represent flow of food and energy through various organisms (including plants) and point from the producers to the consumers. Both the food web and food chain include a number of organisms including both producers and consumers (as well as decomposers).
In their simplest form, food webs are made of food chains. Food chains show a direct transfer of energy between organisms. A chain might involve a mouse eating some seeds on the forest floor.
for example A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
