Answer:
2. octopuses
Explanation:
A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus.
Octopuses belongs in class Cepholopoda. So, the correct option is (B).
What is Cephalopod?A cephalopod is defined as any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus where specifically marine animals with bilateral body symmetry, a prominent head, and arms modified from primitive molluscs or is characterized by a set of tangents foot. These animals use gills to breathe and are invertebrates (lack backbones).
Cephalopods are most notable for their many arms and soft bodies, while ancestral cephalopods are known mostly from their shells because they are well preserved as fossils. The octopus, squid, cuttlefish, and chambered nautilus are familiar representatives.
Thus, Octopuses belongs in class Cepholopoda. So, the correct option is (B).

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.

1. The peppered moth is found in England during the industrial revolution. Coal was used as the top fuel during this. The problem with coal is that it is very dirty
and produces soot. This soot begins to cover the trees. Eventually the trees become darker, see the picture on the right. Use the data below to explain what
happened
Answer:
This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.

Velocity is The amount of time it takes an object to move from point A to point B. Therefore, option B is correct.
What is velocity?When an item is moving, its velocity is the rate at which it is changing position as seen from a particular point of view and as measured by a certain unit of time. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed). The various forms of velocities include uniform, variable, average, and instantaneous velocities.
There are countless practical uses for velocity, but one of the more frequent ones is figuring out how quickly you (or anything in motion) will get somewhere from somewhere.

Distinguish between an antibiotic and a pathogen.
An antibiotic is designed to kill bad cells to help aid illnesses. However, a pathogen is like a virus or a bacteria that can give a disease. Doctors observe pathogens on a atomic and cellular level to alienate the pathogens weaknesses and what does or doesn't kill it. An antibiotic is commonly used to kill these pathogens and prevent infections.
Basically, the big difference between an antibiotic and a pathogen, is that an antibiotic is used as a source of protection and a pathogen is a seperate living virus (disease). Both are key components of finding cures for harmful viruses and illnesses.
