The arthropods with three body sections, three pairs of legs, and one or two pairs of wings are the _______
Answer:
Insects
Explanation:
Insects, like ants, have three body sections, the head, thorax, and abdomen. They have three pairs of legs, three on each side of the body, six legs. And some ants have wings.
The arthropods with three body sections, three pairs of legs, and one or two pairs of wings are the insects.
What are the characteristics of arthropods?Arthropods are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda.
Insects such as ants, dragonflies, and bees. Arachnids such as spiders and scorpions. Myriapods (a term which means “many feet”) such as centipedes and milipedes. Crustaceans such as crabs, lobsters, and shrimp.
All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.

3. population
2. community
4. ecosystem
5. biome
5. biosphere
Explanation:
Biological term related to the number of individual organisms from smallest to largest is organisms, populations, communities, ecosystem, biome, and biosphere.
An organism is a single organism or unity entity in a population, a population is a group of similar individuals that combinedly form a community with other types of population.
A community is a group of various types of populations, that interact with one another. If a community interact with other biotic and abiotic factors it is known as an ecosystem that together with other ecosystems forms a biome

B. preventing mutations from occurring during DNA replication
C. helping from the sugar-phosphate backbone of DNA molecules.
D. providing the instructions for the traits of an organism.
Answer:
D. providing the instructions for the traits of an organism
Explanation:
It can't be A because RNA is used for replication not DNA
It can't be B because mistakes in the RNA are what causes mutation.
It can't be C because sugar phosphate wouldn't be in the nucleus.

words inside the box.
1. The main artery of the body, supplying oxygenated blood to the circulatory
system.
2. The upper right chamber of the heart that receives oxygenated blood from the
lungs.
3. The chamber within the heart that is responsible for pumping oxygen-depleted
blood to the lungs.
4. The artery carrying blood from the right ventricle of the heart to the lungs for
oxygenation.
5. Is the thickest of the heart's chambers and is responsible for pumping oxygen-
ated blood lu tissues all over the body.
Answer:
1. Aorta
2. Left atrium
3. Right ventricle
4. The pulmonary artery
5. Left ventricle.
Explanation:
The aorta is the main artery of the body that carries the oxygen-rich blood to all the body parts except the lungs from the left ventricle. It is divided into main coronary arteries or blood vessels.
The left atrium is one of the heart chambers, it is located in the upper part of the heart on the right side that receives the oxygenated blood from the lungs through the pulmonary vein.
The right ventricle is the chamber of the heart that pumps the deoxygenated blood to the pulmonary valve to MPA to the lungs to get oxygenated.
The pulmonary artery or the main PA (MPA) carries the oxygen-depleted blood from the right ventricle into the lungs, where blood becomes oxygenated.
The Left ventricle is the thickest muscle chamber of the heart responsible for the pumping oxygen-rich blood to the circulatory system and to the body through the aorta.

The part of the following options that are not a long-term effect of mining in the Picher Mining District is the increased amounts of vegetation.
Picher Mining District is an area located in Ottawa, Northeast of Oklahoma. In this area, mining activities are being carried out and these activities can have long-term detrimental effects or complications to respiratory organs.
Miners are required to practices safety rules during mining activities and periodically go for check-ups to extract any harmful substances away from the body system.
Therefore, we can conclude that in an area where mining activities are being carried out, the effect of mining which is not a long-term effect is the increased amounts of vegetation.

I HOPE THIS HELPED YOU!8. A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? Answer
Answer:
the cell was submerged in a hypotonic solution
Explanation:
The cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.
The plant elodea contains cell membrane and cell wall.
The cell wall is an elastic structure that is permeable to all molecules.
The cell membrane is however, selectively permeable.
For the plant to survive and function well, the fluid its submerged into must be isotonic or be able to maintain an osmotic balance.
When placed in a hypertonic solution, a strong concentration, exosmosis occurs.
Water flows out of the cell into its surroundings.
As a result, the vacuole shrinks and eventually pulls the cytoplasm from the cell wall.
Therefore, the cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.

does anyone know how to make my voice deeper I'm ftm so I need help
Hey I have a suggestion if you're still wondering!
So this method actually helped me a lot.
So start by tilting your head downward and by humming in your regular pitch. Then slowly raise your head while continuing to hum. And finally tilt your head back down. And now your voice is deeper than before you started the process.
This helps your vocal cords to become deeper. You can do this as many times you need until you're satisfied. But please be careful and don't do it too much. The first time I did it, I felt really proud. And the day after my throat hurt. I'd say that doing it only once actually lasts a couple hours!
