Explanation:
first is meiosis, second is h. chromosomes, third is chiastsa, fourth is variation, and fifth is exchange
Answer:
The tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned with each other. The synaptonemal complex also supports the exchange of chromosomal segments between non-sister homologous chromatids in a process called crossing over.

In an experiment, a scientist places human red blood cells in seawater. What changes do you think would be made to the red blood cells due to osmosis? Cite facts about osmosis to support your prediction.
Answers
Osmosis is when water diffuses into (for example, a plastic bag), so I think the red blood cells would have more water in them and probably increase in size.
What is Osmosis?The net movement of solvent molecules through a semipermeable membrane is known as osmosis. Since the movement is downward and goes from greater to lower concentration, it is comparable to diffusion.
However, in osmosis, the movement must take place through a membrane that is semipermeable or selectively permeable. It cannot be referred to as osmosis without this component.
The main components of a solution are the solute (a material that needs to dissolve) and the solvent (the component that dissolves the solutes). To determine if a solution is isotonic, hypotonic, or hypertonic in comparison to another solution, the constituent concentrations of the two solutions must be compared.
Therefore, Osmosis is when water diffuses into (for example, a plastic bag), so I think the red blood cells would have more water in them and probably increase in size.

c. Mummified
d. Remains of Organism
Answers
Answer:
It would be D. Mummified
Explanation:
Mummified things are caused by humans using processes to preserve the body after death by deliberately drying or embalming flesh. However fossils are a natural way of preserving items and organisms.
Mummified things are not a type of fossil. Thus, the correct option is C.
What are the fossils?Fossils are the preserved remains of the organisms such as plants and animals whose bodies were buried in the sediments, such as sand and mud, under the ancient seas, lakes and rivers. Fossils can also include any other preserved trace of life that is typically more than 10,000 years old.
Mummified things are the methods of embalming, or treating the dead bodies, that the ancient Egyptians used, the process is called mummification. Using the special processes, the Egyptians has removed all the moisture from the body, leaving only a dried form that would not easily decay.
Therefore, the correct option is C.

8. Which of the following is true of osmosis? a. Osmosis is the movement of oxygen across a membrane. b. Osmosis requires the use of the energy molecule ATP. c. Osmosis is a type of passive transport. d. Osmosis moves against the water concentration gradient.
Answers
Answer:
Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated. Illustration of osmosis.
Explanation:
It is verified from Khan Academy a trusted website such as Brainly.
The statement that is true of osmosis is that "Osmosis is a type of passive transport".
WHAT IS OSMOSIS?
Osmosis is the movement of water molecules from the region of higher concentration to a region of lower concentration through a semipermeable membrane. Osmosis, like diffusion, is a kind of passive transport meaning that it does not require the input of energy (ATP) since it moves water down (not against) the concentration gradient.Therefore, osmosis is a passive transport and not an active transport.
