Answer:
Water separates polar molecules from each other by forming hydrogen bonds.
Explanation:
A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.
An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

Explanation:
7(c)(i). The diagram 7.2 shows the materials used by Claudia for preparing
tea. Claudia finds that the colour of the tea is light. Why? *
Answer: Because she used cold water
Explanation:
Tea leaves contain different flavors that dissolve in water to give it its distinct taste as well as its color. If water is hot, the flavors will dissolve quickly due to the fast movement of the heated water molecules.
If the water is cold however, as is the case in the above scenario, the flavors will take longer to dissolve in the water which means that the tea's color will not change drastically leading to a light tea.

Explanation:
Why does water have "surface tension"?
Answer:
Hello!
Explanation:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken. Hope this helps!

what causes the splitting of the phosphate group off of ATP
Answer:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
Explanation:
DNA is made up the nucleotide bases: A C G U and RNA is made up the nucleotide bases A T C G

What is made possible by a high concentration of auxins in a plant's shoot and root
tips?
a) hydrotropism
b) thigmotropism
c) phototropism
d) gravitropism
Answer:
phototropism
Explanation:
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
Phototropism made possible by a high concentration of auxins in a plant's shoot and root
The correct answer is C
What does a plant's phototropism entail?A plant can maximize photosynthetic light absorption in the aerial portion and water and nutrient uptake in the roots by using phototropism, or the differential cell elongation displayed by a plant organ in response to directed blue light.
What occurs during phototropism?
Positive phototropism, or growing toward the light, is the term for how a plant stem reacts to light. A negative phototropism, or root growth away from the light, is the term used to describe how a plant root reacts to light.

Question 2
Do you think the amount of foam in the glasses will differ? Write down your prediction.
The correct answers are
respirationcarbon dioxiderespirationWhat is the formation of foam?The formation of foam is a process when the small bubbles of the gas get trapped inside a solid or a liquid a form is made and gets made by the tapping of millions of small bubbles and can be seen in marshmallows. The process of foam formation is thus through dispersed medium and in general gas is present.
The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.

Which of these disorders, in which blood does not clot normally, can a technician diagnose through genetic testing? A. malaria B. diabetes C. hemophilia D. rabies
Answer:
Hemophilia
Explanation:
Hemophilia is a disorder in which the blood fails to clot normally because it lacks enough blood-clotting proteins resulting in excessive bleeding from injuries. Other symptoms include:
Unexplained and excessive bleeding after surgeryLarge or deep bruisesPain or swelling in knees and jointsPresence of blood in urine or stoolBleeding into the brain which could sometimes occur from slight knocks to the headIt is a genetic disorder in that it occurs due to a defect in the genes. The disorder is located in the X chromosome found in females. Diagnosis is through genetic testing.

Explain How are speed and pressure of a fluid related?
Answer:
The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.

Which sequence best explains the relationship between DNA and protein structure and function?
DNA → gene → protein → trait
DNA → amino acid triplets → protein → trait
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA shape → amino acid sequence → protein shape and function
ty <33
Answer:
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
Explanation:
From Google:
"The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides [base triplet] in the gene (DNA) encoding it."

The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.
It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.
This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.
Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.
Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.
It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
Thus, having an optimum temperature is essential in functioning of enzymes.

What is an amniote, and which animals on this tree are amniotes?
Amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.
What are amniotes?They are an extensive group of animals such as reptiles, birds or mammals that have amnions during their embryonic phase.
The amnion is a fetal membrane that lines the chorion and delimits the amniotic cavity, that is, it is an internal membrane or closed sac that surrounds and protects the embryo.
Therefore, we can conclude that amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.

Rosa uses a microscope to compare and contrast a group of cells. She sees that the cells are joined together, so she knows that they are from one organism. She also sees that all of them have cell walls. Rosa could be looking at: (HIGHLIGHT THE CORRECT ANSWER)
Answer:
plant cells
Explanation:
Rosa could be looking at plant cells.
Plant cells are generally joined together when tissues of plants are viewed under the microscope and each cell is usually with a cell wall. Animal cells, on the other hand, do not have cell walls.
Tissues are generally composed of similar cells that have been aggregated together to perform a function in the body of organisms. Both plant and animal tissues consist of many cells but only plant cells have cell walls.
