5. Read the following passage.
A small amount of oil can be used to produce a large amount of energy. Because of this, oil has changed the way we live. Our cities are built for cars, which run on oil in the form of gasoline. People have grown used to the idea of being able to hop in their car and drive anywhere they want, for a relatively low price. And our country has a large network of gas stations already in place to make this possible.
However, there is only so much oil underground. Once we have taken all the oil from underground, it will not be replaced. As oil starts to run out, the price will keep increasing. Also, oil releases greenhouse gases when burned, but that is not the only effect it has on the environment. Drilling for oil is a difficult process and can cause environmental damage. In the drilling area, organisms can lose their homes or be killed. Oil is also drilled offshore, which means it is drilled from the ocean floor. This can cause problems for marine life. One of the worst outcomes is when oil is spilled into the ocean, because this is very difficult or even impossible to clean.
a) Based on this passage, what are the pros and cons of using oil? (2 points)
Think about the good and bad things that the passage mentions.
b) How might society affect science when it comes to developing oil-based technology? (1 point)
Think about concerns or needs people may have.

Infectious Disease Investigation
The students are to investigate an infectious disease.
They will choose a specific infectious disease, such as the flu, common cold, or
COVID-19, and research its causes, symptoms, and preventive measures.
Students are to create informative posters or presentations about the disease,
including its transmission methods and ways to protect oneself from infection.
They will explain the importance of personal hygiene and vaccination in preventing
the spread of infectious diseases.
Following the summer vacation, the students will be given an opportunity to present
their findings to the class or organize an "Infectious Disease Awareness Campaign"
where they can share their posters or presentations with their peers.

Why are coconut trees found in coastal areas?
Answers
The warm, humid climate near the ocean is ideal for coconuts, which require constant moisture. Coastal locations also provide easy access to water, whether from rainfall or seawater absorption through the roots, to keep the coconut palms hydrated. Sandy soil, abundant at the coast, allows the coconuts' extensive root systems to spread and helps retain moisture.
In addition, coconut palms are well-adapted to withstand salty winds and wind-borne salt spray from the ocean, bending but not breaking in strong storms. Their flexible trunks and fan-like leaves help them cope with windy conditions.
Coconuts near coastal areas provide ecological benefits as well. Their root systems stabilize beach soil and reduce coastal erosion. Coconut palms offer shelter and food for coastal wildlife like birds and crustaceans.
In summary, the combination of warm, moist air; access to water; suitable soil; and ability to endure coastal weather make seaside locations a coconut palm paradise where these trees can thrive.

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.
how does the organization of the organism work together to function properly
Answers
Answer:
Like cells and tissues, organs seldom work alone. They "cooperate" with one another and form specific organ systems. Organ systems are the fourth level of organization in living things. An organ system is a group of organs working together to perform a specific function for the organism.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
25 PTS MIGHT GIVE BRAINLIEST Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answers
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explanation: i hope this can give you a little push!
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.
