Name some organs that the diaphragm pushes against during inspiration
1. Would the pollution problems caused by cars and trucks be completely solved if they all became electrically powered overnight?
2. Name one challenge we need to overcome by using solar panels
Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.
n 2000, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils.
Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer’s assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues.
Before laying eggs, female birds store calcium inside their bones that they will need to make eggshells. This layer of bone is called medullary bone. In the T. rex leg bone, Dr. Schweitzer found tissue just like the medullary bone of birds. The dinosaur was a female! If Dr. Schweitzer’s hypothesis is right, she is the first scientist to identify the sex of a T. rex. Which organ system includes the bones?
A. skeletal system
B. muscular system
C. reproductive system
D. integumentary system
Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found and is the first scientist to identify the gender of a T. rex, the organ system is the skeletal system, as it includes the bones that are present in Option A.
What is the significance of the skeletal system?The skeletal system, which provides structural support, is important for animals as it protects vital organs, supports muscles, and helps in movement. Also, the bones synthesize the blood cells, such as the red blood cells, which carry nutrients and oxygen, it also maintains the individual's balance and posture and provides a veil over the fossil records.
Hence, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found and is the first scientist to identify the gender of a T. rex, the organ system is the skeletal system, as it includes the bones that are present in Option A.

Explanation:
Which of the following is *true* of the placenta? Question 18 options: 1) It fully develops six months after birth. 2) It forms during the seventh month of prenatal development. 3) It is the fluid-filled sac that houses the developing embryo and fetus. 4) It allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material.
Answer:
4) It allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material.
Explanation:
The placenta is an organ present in all mammals. She is confirmed between the 6th and 8th week of pregnancy and has as main function the exchange of substances between the mother and the fetus. Among these substances are nutrients, gases and even secretions. The placenta also has the function of fighting infections and promoting immunity to the fetus, in addition, it can act as the lung, the intestine and the liver, while the fetus does not develop its organs.

Three complex carbohydrates that are very important in living things are starch, cellulose, and glycogen (see below).. All three of these polysaccharides are polymers of glucose, yet they behave very differently in our bodies. We can digest starch and glycogen, but not cellulose. Examine the drawing of these three polysaccharides below. What differences can you see between these molecules that might explain why
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.

which of the following best describes how the Sun creates wind on Earth
The energy of the sun heats the land unevenly, creating wind.
What is Earth?Earth, the third planet from the Sun, is the planet where all known life is found. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water.
The ocean covers roughly 70.8% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Earth's surface is made up of continents and islands for the remaining 29.2% of its total area.
Several slowly moving tectonic plates that make up the Earth's surface combine to create mountain ranges, volcanoes, and earthquakes. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet.
Therefore, The energy of the sun heats the land unevenly, creating wind.

What is the life cycle of the sun? What are the phases of its life? Birth What is it now? ________________ What will it become? ______________ What will it be called as it dies out? _______________
Answer:
Main sequence, red giant, white dwarf.
Explanation:
The life cycle of the sun is called as solar cycle and is the phase of solar development. There are about seven-stage in its life cycle. Starting with the birth of the sun that is found in the solar nebula theory took place about 4.56 billion years. The sun starts to enter the T Tauri stage, followed by the main sequence stage where the sun is currently in. After this stage that is when the sun runs out of hydrogen from its core. It will produce violent helium flashes and will shrink its size. When this happens it will reach the tip of the red giant stage. Later on, the naked core will form into a white dwarf.PLEASE HELP, I NEED THIS TO PASS xx,

g The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. it rises to the surface and absorbs wavelengths needed by aquatic plants it causes the water to become murky it decomposes endothermically causing the temperature of the water to decrease below the limits within which most aquatic organisms can live it causes oxygen depletion in the water it causes death of bottom dwelling organisms because it agglutinates and settles to the bottom, poisoning bottom dwelling organisms
Answer:
It causes oxygen depletion in the water
Explanation:
When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.
Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.
Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.
Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.
When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.
