The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).
The purpose of meiosis is to create gametes. Thus, it reduces the number of chromosomes to half.
What is meiosis?In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid or have only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are gametes.
In humans, autosome cells contain 46 chromosomes, while gametes contain 23 chromosomes. Hence, the main purpose of meiosis is to divide the genetic material in half.

what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s
Answer:
We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J
Explanation:
What landform is created when 1 oceanic plate and 1 continental plate move apart at a Divergent Boundary?
Answer:
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.

Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves.
The skin cells of a scorpion organize together to make a hard covering called a carapace, which helps protect the scorpion. What is the term for a group of similar cells working together?
Question 11 options:
system
organism
organ
tissue
The skin cells of a scorpion organize together to form a hard covering called a carapace, which helps protect the scorpion. "Tissue" is the term for a group of similar cells working together. The last option is the correct answer.
What is a tissue?In a single-celled organism, cells perform all of the body's functions, whereas in multicellular animals, cells join together to form tissue, tissue joins together to form organs, and organs join together to form organ systems, and all functions are divided. By the time zygote formation occurs, there is only one cell present, and that cell has been divided, specialized, and assigned specific functions.
Some cells make stem cells, some make epithelial cells, and so on. The tissue is a group of cells having a similar function, such as epithelial tissue, which has many cells but all of them perform the same function, that of a skin cell; all of them have sweat glands, etc.
Hence, "tissue" is the term for a group of similar cells working together. The last option is the correct answer.

What can happen if a population of organisms disappears from the food chain in an ecosystem with low biodiversities, such as the tundra?
Answer: If the population of an organism dies out, then the animals on top of it on the food chain are going to die, since they will have no other food to rely on. Or, they will have to find a new source of energy if they do not.
This is why we should not try to kill any animals, even too much fishing can cause the same problem.

Define 3 of the major parts of the skeletal system and list the
function(s) of each (bones, ligaments, and tendon, cartilage.)
Answer:
Bone
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
Ligament
Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.
Tendon
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Cartilage
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

In a balanced ecosystem with predators and prey, if the prey population decreases then....?
Answer:
Predator population will also decrease
Explanation:
This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.

What is density of a liquid with mass of 17.4 and a volume of 20 mL ? Would this liquid float or sink at room temperature based on its density and the known density of water?
Answer: The density of the liquid is 0.9 g/mL
. Hope this helps but I can not answer the second part. Hope that it is beneficial to you anyway! :)
(Edit) This might help you figure it out: The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
