A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis

, because energy is being used to move molecules with the concentration gradient. B.Active transport, because energy is being used to move molecules against the concentration gradient. C.Facilitated diffusion, because energy is being used to move molecules with the concentration gradient.

Answer:

B.Active transport, because energy is being used to move molecules against the concentration gradient

Explanation:

Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.

Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.

Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.

ycow [4]

Answer:

This can be caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. ... However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.

Explanation:

I hope this helps I'm not so good at explaining.

Compare photosynthesis to an everyday process
mixer [17]
Hello.

A detailed comparison between all of the above details of photosynthesis to the process or subject of your choice?For example if we are going to do cake we are going to need to get all the ingredients so we could start baking when we start mixing the ingredients the cake is almost ready to be baked. We then put it to a pan and put it in the oven to start to bake, And then we have cake. This is like the process of photosynthesis because photosynthesis takes in sun light and then converts oxygen to glucose. The Cake takes in its ingredients and then it gets bake and it gives us energy.

Question 6: Why might islands be good ecosystems to study the outcomes of the founder effect?
Svet_ta [14]

Answer: This can be useful site to study the diversity of organisms.

Explanation:

The founder effect is the known phenomena proposed by Ernst Meyer. It occurs when a small number of organisms leave the larger population. The genetic variation will be lost when a new population is established by the small population. Due to lack of genetic variation the new population becomes phenotypically and genotypically different from the parent population. This process lead to speciation.

The islands are the regions where few organisms can be found, those have migrated from the native land. Thus the study of diversity of these organisms will become simple.

The most important adaptive advantage associated with the filamentous nature of fungal mycelia is
MAVERICK [17]

Answer:

d. an extensive surface area well suited for invasive growth and absorptive nutrition.

Explanation:

Fungi have an extracellular nutrition. These means enzymes are released to environment to start degrading macromolecules which can be later be absorbed (absorptive nutrition) through cell membranes. Having multiple spots (bigger surface area) through which it can nurture speeds up the rate at which it can grow leading to a faster growth and higher competition over resources.
