How many different versions of a gene are carried in a single normal cell?

All organisms must perform life-sustaining metabolic processes in order to survive.

Alik [6]

Explanation:

Unicellular organisms or single celled organisms that are made up only of one cell. Hence the name.
Unicellular organisms are further divided into Prokaryotic and Eukaryotic organisms
Examples of prokaryotic organisms are bacteria and Eukaryotic are protozoa and unicellular algae, however many eukaryotes are multi cellular as well.
These organisms have to carry out life sustaining metabolic processes for their survival.
These processes are metabolism, homeostasis and reproduction. Metabolism is important as it involves conversion of food into energy for cellular processes. Homeostasis for maintaining a constant internal physical and chemical conditions and reproduction is by cell division.
Multi cellular organisms as the name says unlike unicellular organisms consists of more than one cells.
Examples of multi cellular organisms are animals, land plants etc.,
Metabolic process in multi cellular organisms is a broad category of processes happening for these organisms which involves chemical reactions and pathways that happen at organismal state, transporting substances between the cells.

Based on the definition of a watershed, how many different watersheds were there in your model? Explain how you determined this

cupoosta [38]

Answer:

Water shed is created when an area or land separates the water flowing to different rivers, basin and seas.

Explanation:

Water shed are of different types-

Large water sheds-Contain well developed channel networks.
Small water sheds-Contain dominant land phase.
Urban watershed-It is dominated by building,roads,pavements.
Agriculture water shed-
Forest water shed-Evapotranspiration is the dominant component of the hydrologic cycle.
Mountain water shed-mountain is the dominant component that separates the water flow.
Desert water shed-Sand dunes sand mounds that are formed by blowing air causes separation of water flow.
Coastal watershed-Coastal area may partly be urban and is dynamic contact with sea.The hydrology is influenced by tidal action.

Explain how endocytosis, digestive enzymes and exocytosis work together to get rid of bacteria

erma4kov [3.2K]

Answer: Endocytosis brings materials to the inside of the cell while exo takes them out. Exoocytosis has the vesicle being formed in the golgi apparatus which then fuses with the membrane, while endo has the vesicle. formed from the cell membrane which then gets into the cytoplasm.

In piranha, fish with large teeth represent the dominant trait. Because the dominant trait masks the recessive trait, in a popul

vodomira [7]

Answer:

B. 25%

Explanation:

Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.

Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:

Aa x Aa = AA, Aa, Aa and aa

The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.

Hence, about 25% of the next generation of the population is ecpected to have small teeth.

The correct option is B.
