Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.

Why isnt there a solar eclipse during every new moon?
Answer:
Eclipses do not happen at every new moon, of course. This is because the moon's orbit is tilted just over 5 degrees relative to Earth's orbit around the sun. For this reason, the moon's shadow usually passes either above or below Earth, so a solar eclipse doesn't occur.
Explanation:
Make this in own words if it's for a test or smth
Explanation:
Solar eclipse don't happen every new moon, because the moon's orbit tilted over degrees relative to the earth's orbit around the sun. The moon's shadow usually passes either above or below earth, so therefore that is the reason a solar eclipse does not occur every new moon

A large protein needs to enter a cell to help preform a function explain what process the cell must use to allow the protein to enter and why
Answer:
The protein is too large to simply diffuse across the phospholipid bilayer of the cell, so it uses phagocytosis to diffuse across, where it is contained in a vesicle and pinched into the cell? Credits to yahoo answer. Hope I could help sweets.
Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.
These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.
Which statement correctly demonstrates the relationship between cellular respiration and photosynthesis?
A: The ATP produced by all cells during cellular respiration can be used by plant cells to produce water molecules during photosynthes
B: The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
C: The oxygen produced by all cells during cellular respiration can be used by plant cells to produce glucose during photosynthesis.
D: The water molecules produced by plant cells during photosynthesis can be used by all cells to produce oxygen during cellular O respiration.
Answer:
your answer is B. The glucose produced by plant cells during photosynthesis can be used by all cells to produce ATP during cellular respiration.
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

What are the main characteristics of epithelial tissues?
they compose glands
they contain blood vessels
they cover the body surface
they form the inner lining of body cavities
they line hollow organs
Answer:
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
The main characteristics of epithelial tissues includes: they compose glands, cover the body surface, form the inner lining of body cavities and line hollow organs.
What is tissue?It is a group of cells having same structure and function.It includes: connective tissue, epithelial tissue, nervous tissue and muscle tissue.What is epithelial tissue?It covers the body surfaces.These are avascular, meaning they do not contain blood vessels.Glands are made up of epithelial tissues.They lines the body's inner cavity and hollow organs.It helps in movement of molecules across the its surfaces.It functions in absorption, secretion and protection.Hence, the correct options are: They compose glands, they cover the body surface, they form the inner lining of body cavities and they line hollow organs.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

How can you test the idea that solar energy is required for the reduction of NADP+ to NADPH?
Answer:
In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

Frederick Griffith made a scientific discovery in 1928. Which best describes
the knowledge about genetics before 1928?
Answer:
Frederick Griffith's discovery on the theory of genetics is credited to his experiment on mice. He subjected them to different strains of pneumonia bacteria. He concluded that there is an unidentified force that leads to the formation of different strains from what the mice were subjected to. This leads to the discovery of DNA, the carrier of traits. Scientist before did not know how the trait is passed on not until Griffith's experiment.

if a cell has 24 chromosomes, how many chromosomes would each of its four daughter cells have after meiosis?
Answer:
Because there are two rounds of division without duplication in between, the genetic content is cut in half. Each of the 4 daughter cells will only end up with half of the genetic content of the parent cell. Therefore, after meiosis, the daughter cells would have only 12 chromosomes each.

In an ecosystem, what form does carbon take after photosynthesis? What form does carbon take after cellular respiration?
Answer:
organic molecules and carbon dioxide
Explanation:
Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas. Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ).
