How does planting can conserve our natural resources?
Answers
1. Prevents soil erosion - Trees and plants help to hold soil in place, preventing it from being washed away by rain or wind. This helps to conserve soil and prevent land degradation.
2. Improves water quality - Trees and plants help to filter water, removing pollutants and reducing the amount of sediment that enters our waterways. This helps to conserve water resources and improve water quality.
3. Provides habitat for wildlife - Trees and plants provide habitat for a wide variety of animals and insects. This helps to conserve biodiversity and maintain healthy ecosystems.
4. Reduces greenhouse gas emissions - Trees and plants absorb carbon dioxide from the atmosphere and store it in their biomass. This helps to reduce the amount of greenhouse gases in the atmosphere, which can help to mitigate climate change.

Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long, narrow tail that originates in the mantle. This type of volcanism, hot spot volcanism, is unique. Why?

The option (D) is correct. All are the characteristics of sulfurous smog.
What is sulfurous smog?
Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal. This type of smog is aggravated by dampness and a high concentration of suspended particulate matter in the air.
Moreover, sulfurous smog is also called “London smog,”. Sulfurous smog results from a high concentration of SULFUR OXIDES in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.
Answers
The skeletal system serves several important functions in the human body. These functions include:
1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.
2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.
3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.
4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.
5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.
6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.
The human skeleton consists of 206 bones in adults. Some of the major bones include:
1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.
2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.
3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.
4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.
5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.
6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.
7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.
8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.
These are just a few examples of the major bones in the human skeleton.
Answer:
Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:
enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.
Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC
supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.
Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

Differences between the Kutchicetus and the Saber-toothed cat:
The Kutchicetus had a large tail for propelling in the water, and thick blubber to stay warm.
The Saber-toothed cat had a short tail, lived in social groups, and weighed twice as much as the lion.
(They both had proportionally small hind legs compared to the rest of its body.)
Explanation:
I know the Kutchicetus had a large tail and the Saber-toothed cat didn't becuase of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Kutchicetus had thick blubber and the Saber-toothed cat didn't because of anatomy and reasoning (the Kutchicetus dwells in water).
I know the Saber-toothed cat lived in social groups and the Kutchicetus didn't because the Saber-toothed cat is related to lions (lions have social groups).

Why are archaea in a different domain from bacteria?
A. They both evolved from eukaryotes.
B. They shared a common ancient ancestor.
C. They developed along different evolutionary paths.
D. They are prokaryotes, but bacteria are eukaryotes.
Answers
Answer:
A. They had independent evolutionary development.
Explanation:
Answered correctly. got 100%!
Archaea are in a different domain from bacteria because they both are evolved from eukaryotes. Thus, the correct option is A.
What are Archaea and bacteria?Archaea is an independent domain of single-celled organisms. These microorganisms generally lack a cell nuclei and are therefore prokaryotic organism. Archaea are the organisms which were initially classified as bacteria.
Bacteria are ubiquitous, mostly free-living organisms which are often consisting of only one biological cell. Bacteria constitute a large domain of prokaryotic microorganisms. They are typically a few micrometers in length, bacterial species were among the first life forms to appear on this Earth, and are present in most of its habitats.
