Explanation:
Humans use their lungs to inhale oxygen from the air. But worms, fish, crabs and other underwater animals use gills to get oxygen from the water. As water moves across an animal's gills, oxygen is removed and passed into the blood. Gills work better when there is more oxygen in the surrounding water.

what is brain cancer ?
Answer:
Brain cancer is an overgrowth of cells in your brain that forms masses called tumors. Cancerous, or malignant, brain tumors tend to grow very quickly. The symptoms of brain cancer depend on the size and location of the tumor.
Common brain cancer symptoms include:
headaches that are usually worse in the morning
nausea
vomiting
a lack of coordination
a lack of balance
difficulty walking
memory lapses
difficulty thinking ,speech problems
.Many of the symptoms of brain cancer are also caused by other, less serious conditions. There’s no need to panic if you’re experiencing these symptoms, but it’s a good idea to visit your doctor to have your symptoms investigated, just in case.
Explanation:
Changes to _______ can be ascribed to glacial melting. a. Earth’s surface b. CO2 levels c. coral reefs d. water pollution
Answer:
a. Earth’s surface
Explanation:
The glacial process is a geomorphological process caused by the action of ice, snow, and frost.
When the water flows away from the glacier melting of the sea, it goes to the ocean, so the amount of water in the ocean provokes the changes on the coasts. This is happening slowly and, in the end, we are starting to see changes in the Earth's surface
Answer:
Earth’s surface

A doctor treats a patient with a skin condition with different creams to see which is most effective. What is the independent variable?
1. Skin Creams
2. Skin Conditions
Answer:
1. Skin Creams
Explanation:
An independent variable is the only variable that is changed while the rest is kept the same. In this setup, the doctor is using different creams on the same patient with the same skin condition so the independent variable is the skin cream and not the skin condition.

Which role does photosynthesis play in the flow of energy? (1 point)
Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.
Photosynthesis is how plants break down glucose to use for energy.
Photosynthesis allows plants to create energy for themselves to store and use for metabolism.
Photosynthesis provides radiant energy to all the organisms in the entire food chain.
Answer:
Radiant energy transformation that takes place during photosynthesis
Explanation:
Radiant energy transformation that takes place during photosynthesis
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration

Photosynthesis converts radiant energy to chemical energy to be used by the organisms in the food chain .
What is photosynthesis?
It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

What new details are you able to see on the slide when the magnification is increased to 10x that you could not see at 4x? What about 40x?
As the magnification increases, more specific information, such as the nucleus of cells on the slide, is seen.
What is magnification?
The majority of compound microscopes include objective lenses, which are replaceable lenses. The most popular magnification powers for objective lenses are 4x, 10x, 40x, and 100x, commonly referred to as scanning, low power, high power, and (usually) oil immersion objectives.
More minute characteristics of the cells and the form of the stained nuclei may be seen at a magnification of 40 times. You can see a smaller area of the specimen because of the reduced field of view at higher magnifications. Furthermore, keep in mind that although appearing to be incredibly thin, the item on the slide actually has a thickness.

Which base is found only in DNA?
O adenine
O guanine
O cytosine
othymine
Thymine is the base that is found only in DNA. Adenine, guanine, and cytosine are also present in both DNA and RNA, but thymine is exclusive to DNA. In RNA, uracil replaces thymine.
What are nucleotide bases?Nucleotide bases are the building blocks of DNA and RNA, the genetic material in all living organisms. There are four nucleotide bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine. These bases pair with each other to form the "rungs" of the DNA ladder, with A always pairing with T (or U in RNA) and C always pairing with G.
The sequence of nucleotide bases in DNA determines the genetic information carried by an organism. DNA replication, the process of copying DNA before cell division, relies on the complementary base pairing of nucleotide bases to ensure that each new strand of DNA has the same sequence as the original.
Mutations, or changes, in the sequence of nucleotide bases can occur naturally or as a result of external factors such as radiation or chemical exposure. These mutations can lead to genetic variations and may have consequences for the organism.

Forest butterflies are often brown. This helps them to
Answer:
Avoid predators
Explanation:
Organisms often mimic their surroundings to escape the predators. This technique is also called camouflaging.
Forest butterflies have also adopted several structural adaptations to avoid predators. Many of them have brown wings with jagged edges so that they resemble dried leaves. In this way, they blend with their surroundings, especially the forest floor, and go unnoticed. On the other hand, butterfly larvae are green in color so that they resemble the leaves on which they feed and avoid predators.

What is the role of ATP when large molecules need to be transported across the cell membrane against the concentration gradient?
The bond between the phosphate groups is broken to store energy.
The bond between the phosphate groups is broken to release energy.
Bonds are formed between the adenine and the ribose to store energy
Bonds are formed between the ribose and the phosphate to release energy.
Answer:
b. the bond between the phosphate groups is broken to release energy
Explanation:
Phosphate groups are negatively charged => there is a pull between the two groups=> it's easy to break this bond & ATP is unstable
=> ATP has a lot of free energy
breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)=> delta G <0
=> breaking this bond releases energy
the energy released by ATP is then used to transport large molecules against the concentration gradientThe bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.
ATP is also called as the energy factory for the cell. It is also required for various metabolic processes within and outside the cell. It has a role in transfer of macromolecules like proteins, lipids, and other into and out of the cell. It is difficult for molecules to be transported into and out of the cell across a cell membrane against a concentration gradient for this energy in the form of ATP is required. When the hydrolysis of the molecule of ATP occurs it releases the phosphate group along with the release of energy this energy is necessary for the active transport of molecules against the concentration gradient across a cell membrane. Hence, the bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.Learn more about ATP:
