Why does our heart need two parts that are completely separate from one another?
Answer:
the heart is separated into two sides so that it can carry out its function well. The right heart contains deoxygenated blood and the left heart with oxygenated blood. the two sides are separated from each other so that the blood from the two sides don't get mixed. this leads to effective oxygenation of the deoxygenated blood in the right heart through pulmonary circulation and effective oxygenation of the tissues in the different parts of the body by the oxygenated blood of the left heart through systemic circulation.

Twins creating a child somewhat different to them
Answer:
a single being cloned into an identical twin
Explanation:
I'm not 100% sure but I learned this in biology not that long ago
Answer:
A single person being cloned into an identical twin
Explanation:
I think its this one because the process of cloning is probably always going to be more exact than any natural birth

You are a biologist looking at samples of pond water. Using a microscope to investigate your samples, you identify a cell with a nucleus. Briefly explain how you know immediately that this is not a prokaryote. Additionally, without further investigation, would you be able to determine if it was a plant or an animal cell?
Answer:
You know it's not a prokaryote, because prokaryotes do not have a nucleus. You would not be able to determine if it was a plant or animal cell without further investigation because both have a nucleus.
Plant cells do have organelles that animals cells don't such as chloroplasts and cell walls, but you would have to investigate further.
The cell is eukaryotic one as it does not possesses a nucleus. For determining that the cell is of plants or of animals, the best way is to look at the criteria like cell wall, vacuoles, etc., which are present only in plant cells.
What is eukaryotic cell?Eukaryotes are organisms with nuclei in their cells. Eukaryotes include all animals, plants, fungi, and many unicellular organisms.
They are members of the Eukaryota group of organisms, which is one of the three domains of life. The other two domains are Bacteria and Archaea.
Plant cells have both a cell wall and a cell membrane. The cell wall surrounds the cell membrane in plants.
This is what gives plant cells their distinctive rectangular shape. Animal cells have only a cell membrane and no cell wall.
A cell wall, chloroplast, plasmodesmata, plastids, and various organelles are all found in plants.
Animal cells do not have cell walls, but they do have organelles such as tight junctions and cilia. The meristematic system, which is located at the tips of roots and stems, is responsible for plant growth.
Thus, this way, one can identify with further investigations that if it was a plant or an animal cell.

Describe a general animal life cycle.
Answer:
The four stages of the life cycle of an animal are birth, growth, reproduction and death. Most animals appear similar to their adult counterparts at birth, but some types of animals, including most insects, go through a radical transformation called metamorphosis during their growing stage.

Georgette drew a diagram to compare chytrids and sac fungi.
Which description belongs in the area labeled Z?
a-Have reproductive cells with flagella
b-Contain cell walls
c-Release chemicals to break down food
d-Lack hyphae
Answer:
D
Explanation:
Chytrids lack hyphae.
Answer:
d-Lack hyphae
Explanation:
It refers to the difference between them and also the characteristics which chytrid has.
They both have cell wall.They both are reproductive cells with flagella.fungi release chemicals to break down food but chytrids do not.fungi has general hyphae whereas chytrids does not.

Answer:
C. Out of the leaf by diffusion.
Explanation:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. The solvent moves to dilute the concentrated solution and equalize the concentration on both sides of the membrane.
Examples of Osmosis: Examples include red blood cells swelling up when exposed to freshwater and plant root hairs taking up water. To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane.
Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Examples of Diffusion: Examples of diffusion include the scent of perfume filling a whole room and the movement of small molecules across a cell membrane. One of the simplest demonstrations of diffusion is adding a drop of food coloring to water. Although other transport processes do occur, diffusion is the key player.
Based on the above information, your answer is most likely

The presence of Permian-aged Mesosaurus fossils in both Brazil and Africa is evidence that South America and Africa were once joined as part of a single continent. Alfred Wegener proposed Pangea.
Alfred Wegener and PangeaAlfred Wegener was a geologist who proposed all continents were once a single landmass known as Pangea.
Alfred Wegener indicated that this landmass broke and continents separated and drifted to their present locations.
Wegener developed these ideas in a publication known as "the Theory of Continental Drift".
