Answer:
The integumentary system is similar to a cell membrane in that both structures create a protective barrier against the outside world. How is a nerve cell specialized? Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body.

Answer: 5. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain in the mesohyl), delivering phagocytized sperm from choanocytes to eggs, and differentiating into more-specific cell types. 6. Sponges form symbiotic relationships with a variety of microorganisms, including bacteria and algae. A symbiotic relationship between organisms is a close ecological association between two species that may be mutually beneficial or may benefit one partner at the expense of the other. However, humans are still damaging sponge populations with weighted nets and even taut fishing lines, which can slice sponges apart by accident. As a rule, anything that can affect the ocean floor will have a negative impact on sponges, as they have never developed protection against impacts. brainliest??
Explanation:
Explanation:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.
<h3>
Transitional fossils</h3>
Transitional fossils are any fossilized remains of a life form which show common traits to both an ancestral group and its derived descendant group.
<em> Australopithecus afarensis </em>is a hominid that represents an evolutionary transition between modern bipedal humans and their quadrupedal ape ancestors.
Similarities in DNA
All species in the world share some amount of DNA. Species that are more related to each other share bigger amount of DNA than species that are less related. For example fruit fly and modern humans share 61% of their genome and chimps and humans share 96%.
Evolution of the eye
The PAX6 gene controls where eyes develop in animals ranging from fruit flies, octopuses, to mice and humans.
Answer:
I believe refraction plays a big part on why we can distinguish water from air. As light hits the water, it's bent to a different angle because it's slowed down. If you've ever held a pole in the water, you'll see a break in the line where it meets the water. That's the effect of refraction.
