Answer:

The food chain that is described in the question is called Grazing food chain.

Explanation:

Grazing food chain is a type of food chain that contain producers at the lowest tropic level.The producers can manufacture their own food by photosynthesis process. Here grass act as producers.

The second topic level of grazing food chain contain primary consumers which consume producer. Here grasshopper eat grass,as a result grasshopper act as primary consumers or herbivores

The third tropic level of grazing food chain contain secondary consumers that feed on primary consumers. Here snake eats grasshopper,as a result snake act as secondary consumers or primary carnivores.

The highest tropic level of grazing food chain contain tertiary consumers or secondary carnivores.Hawk eats snake,as a result hawk act as Tertiary consumers or secondary carnivores.

Answer:

I think that Viruses are not alive so Being composed of molecules that are found in cells (nucleic acids, proteins, lipids and complex sugars) and having the capacity to evolve, viruses are often said to be alive. But they aren't alive because they arent a living thing.

Firdavs [7]

Answer:

"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>

Explanation:

Biological membranes are formed by two lipidic layers, proteins, and glucans.

Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.

Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.

Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.

Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occu

fenix001 [56]

Answer:

B) Prokaryotic DNA is much smaller than eukaryotic DNA.

Explanation:

In biology, one event is correlated with the other event or structure like observed in the DNA. The genetic material of a eukaryote and a prokaryote differ from the other in many ways:

1. The prokaryote possesses only one chromosome which is double-stranded and circular.

2. The eukaryotic organism exhibits more than one chromosome which is not circular.

Since the prokaryotes possess very less amount of DNA then the eukaryotes therefore during DNA replication, the DNA of prokaryote require only one origin of replication from where the replication will start.

Thus, Option-B is correct.
