A scientist named Joseph Connell studied two species of barnacles on the shore of a Scottish island. In the area between the average tide and the neap high tide, he found that the population of Species A was smaller than that of Species B. He removed Species B from one area but left both Species A and B in a similar area. The graph below shows the results of this study.
Based on these data, which hypothesis was Connell most likely testing?
Select one:
The two species of barnacles compete with each other for resources.
The two species of barnacles are closely related to each other.
Barnacles grow larger when they are isolated from other species.
The populations of both species of barnacles increase more in warm water than in cool water.

Answer:
I believe that would be the nerve cell
Explanation:
Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they're structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.

If all of the characteristics of life are required to classify something as “alive”, how can we account for those individuals who are definitely alive, but that do not reproduce (for example, people without children or a sterile mule)?
Answer:
Here is the answer key. Just scroll down to the question and the answer is there.
Explanation:
These organisms are still alive. Reproduction is not important for survival but for the survival of a species.
What is the importance of reproduction?The only way to ensure that the kind of species survives and keeps flourishing on the planet is through reproduction. The process by which organisms give rise to new offspring is called reproduction. It is one of the many defining characteristics of life and loving organisms.
There are some organisms that look and act exactly like their parent/parents. Whereas, other kinds of organisms share similar traits with their parents but are not completely like them. These organisms are unique individuals in their various characteristics.
Some species have two parents, whereas others have just one. It is determined by the method of reproduction by these organisms. It also determines the percent of similarity of the organism with its parents.
Reproduction is basically of two types: asexual reproduction and sexual reproduction. Asexual reproduction involves the development of new organisms by a single parent. Sexual reproduction involves two parents and their fusion of gametes.
Therefore, Reproduction is essential for the survival of a species and not for the survival of an organism.

Please help with science biology ASAP!! Will give brainliest!
Answer:
1) The beaks are different because they each had different purposes, such as the types of seeds the birds eat.
2) Natural selection is that organisms that are better suited for they're environment survive and reproduce.
3) Variation is the differences of one organism's difference from another of the same organism.
4) Biased off the fossils scientist may see the changes that happen over time to them and thanks to the ability of seeing how old a fossil is we may better order them.
5) Mimicry is when one organism "mimics" another, whereas camouflage is when one organism changes to look likes it surroundings.
6) Adaptation is a change or the process of change of which an organism or species becomes better suited to its environment.
7) An endangered species is a species that is very low is sightings or near extinction.
8) A herbivore has a plant biased diet whereas a carnivore has a meat, or other living organism biased diet.
9) Flowers use coloration to use a color to attract birds, and insects to reproduce and pollenate.
10) Charles Darwin was a explorer and scientist that came up with the theory of evolution, which states that through natural selection a species may change, give rise to new species, with a common ancestor.

What is Cladogram?A cladogram is a representation of a potential link between groupings of species, including their shared ancestors. The Greek terms "clados" and "gramma," which mean "branch" and "character," respectively, are the origin of the words "cladogram."
The image gives the impression that a tree trunk is sprouting branches. Yet, the cladogram's form is not necessarily vertical. The diagram's sides, top, bottom, and center can all branch off of it.
Cladograms can be exceedingly complicated, potentially classifying all forms of life, or very simple, comparing only a few types of organisms.
Therefore, The frog has 2 limbs at the back and 2 on the front. a pigeon walks with its two tiny legs.

Match the term to its description.
Term: Chromosphere. Convective zone. Core. Radiative zon.
Definition: A.) Layer of the sun where energy is transferred by thermal conduction.
B.) The central and hottest section of the sun.
C.) Layer of the sun where energy is transferred by convection.
D.) Layer of the sun that is known for its red color and can only be seen during eclipses.
Answer: The answer is the layer of the sun that radiates energy outwards from the sun core
Explanation: the reason why that is becuase the convection zone is a layers which is unstable to convection. And energy is primarily or partially transported by convection
The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.
What is the Sun?It is the central star of our solar system around which the planets and other planetary bodies revolve. Ninety-nine per cent of the mass of the entire solar system is constituted by the sun.
The sun produces a tremendous amount of energy. A part of this energy reaches the earth. The perfect distance of the earth from the sun ensures that this energy supports life on earth.
The sun is considered to be a 'dwarf' star among the other stars studied and observed in the observable universe. The sun has been formed from the material which had been processed inside of a supernova and is present in the outer regions of our milky way galaxy. The sun is made of several layers and each has its own role.
Therefore, The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.
