simplify the following
(-107)-(-97)+(-10)
Answer: -20
Explanation:
Here is the equation to solve:
(-107)-(-97)+(-10)
First and foremost, we should note that:
- × - = +
- × + = -
Therefore, (-107)-(-97)+(-10)
= -107 + 97 - 10
= 97 - 107 - 10
= 97 - 117
= -20

1) List what elements are found in a nucleotide.
2) What is the polymer of a nucleotide?
3) Why are nucleic acids important for all life?
COMPLETE SENTENCES PLZ ILL GIVE BRAINLIEST
Answer:
1) A nucleotide consists of a single sugar, a phosphate, and a nitrogen-containing base.
2) The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide. Nucleotides don't have polymers because they are monomers.
3) They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are DNA and RNA.

Explanation:
Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell
membrane, because is it semi-permeable, allowing small molecules to cross the membrane, but NOT larger molecules, like starch
A starch solution is placed in the dialysis tubing and then the dialysis tubing is placed in an iodine and water solution. lodine is
used as an indicator for the presence of starch. Normally, iodine is a yellow-brown color, but in the presence of starch, it turns a
deep purple. After observing the experimental setup for 20 minutes, the iodine solution remains brown, but the starch solution
inside the dialysis tubing is purple and swollen. Based on what you learned from the lab, starch is MOST likely to cross the cell
membrane at which of the points indicated on the diagram?
ah
ing
Starch requires ATP energy for transport and therefore cannot cross the dialysis tubing into the iodine solution.

How does the fermentation of pyruvic acidin cells contribute to the formation of ATP? A. It completes the oxidation of glucose to CO2, creating ATP. B. It generates lactic acid, which cycles back through the Krebs cycle, producing 2 ATP molecules. C. It converts FADH2 to phosphate, which bonds with ADP. D. It produces 2 NAD+ molecules, which cycle back to fuel the glycolysis reaction, allowing 2 ATP molecules to be produced.

Answer:
Explanation:
Skeletal Adaptations. Giraffes, lizards, and many other known species adapted to their environments through genetic changes to their skeletons. Coloration. Many species have been studied who've adapted to their environment through adaptions in coloring. Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds. However, natural selection does not always go to the optimum. An example of variation is that I have a cat with black fur and one with yellow fur. Trait that can be PASSED DOWN to offspring through genes. Inherited characteristic that INCREASES an organism's chance of survival or reproduction in its environment.
What is one job proteins do NOT have in the body
1.serve as a layer of insulation
2.support the immune system
3.structure for tissues and organs
4.serve as enzymes
Answer:
1. serve as a layer of insulation
is not a job of proteins
Proteins do not serve as a layer of insulation in the body.
WHAT ARE PROTEINS:
Proteins are one of the four biomolecules in living organisms. Proteins are made up of long chains of amino acids linked together by peptide bonds.
FUNCTIONS OF PROTEINS:
Proteins in the body are synthesized to perform varying functions. These functions include:
Enzymes: Proteins are the major components of enzymes responsible for regulating series of biochemical reactions in the body. Structure for tissues and organs: Proteins make up the structural components of many tissues and organs in the body. For example, keratin is a protein found on the skin. Support the immune system: Proteins provide support for the defense system of the body.Therefore, among the many roles that protein play in the body, serving as a layer of insulation is not one of them. It is rather the function of LIPIDS.

A new microbe has been discovered in the rumen of sheep. Microscopy shows no evidence of a nuclear membrane and biochemical studies of the cell wall demonstrate the lack of peptidoglycan. Metabolic studies show that this microbe generates methane. This microbe would most likely be classified in ______.
Since it has no nucleus it's most likely a prokaryote
A new microbe discovered in the rumen of sheep that generates methane, shows no evidence of a nuclear membrane, and biochemical studies demonstrate the lack of peptidoglycan. Such type of microbes is likely to be classified in Archaea.
Archaea is a group of single-celled microorganisms that were first discovered in 1977. Archaea are similar to bacteria and eukaryotes, but they are unique in that they thrive in harsh environmental conditions like extreme heat, high salt levels, and acid environments.
Some archaea can also generate methane gas, similar to the microbe in the given description. Hence, the given microbe that generates methane, shows no evidence of a nuclear membrane, and biochemical studies demonstrate the lack of peptidoglycan would most likely be classified in Archaea.

Put the drinking water treatment steps in the correct order.
Which of the following distinguishes a function of vascular tissue?
transporting water through the plant
shaping the plant's sperm
surrounding reproductive parts of the plant
forming the plant's egg
Answer:
The correct answer is - transporting water through the plant.
Explanation:
Vascular tissues are the conductive tissue present in most of the plants that made up of various cell types mainly phloem and xylem. Vascular tissue is complex and present in different types in different plants.
These two primary parts of the vascular tissues xylem and phloem help in transporting the fluids and nutrients to different parts internally in the plants. The fluids that are transported include water, plant hormones nutrients, and various essential molecules to help plant.
Answer:
transporting water through the plant

The cells of the leaf of the grape plant are able to make sugars which are then transported to the grapes. Describe the process by which sugars are made in a leaf cell.
Answer:
yes
Explanation:
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen

Maria walks up hill to go to school every day. When she reaches the top of the hill, she is always breathing much faster than when she started. How might this affect how her heart is working? Support your hypothesis with evidence.
Answer:
''By doing hard activity, the pumps very fast.''
Explanation:
''By doing hard activity, the heart pumps very fast.'' is my hypothesis. In this hypothesis, I mentioned that during hard activity pumping of heart goes very fast because our body needs oxygen as well as energy in the form of ATP and the only way to get both oxygen and energy is the pumping of heart which supply oxygen to the cell as a result energy is generated in the form of ATP and removes carbondioxide gas by breathing.
If a certain organism is a primary consumer, what best explains its position in the food web? (See picture above)
A. X, because organism X has the same role as the grasshopper
B. y, because organism Y has the same role as grasshopper
C. x, because organism X has the same role as the baby sparrow
D. Y, because organism Y has the same role as the baby sparrow
Answer:
A. X, because organism X has the same role as the grasshopper
Explanation:
In the food web the organism is denoted by X and it shares the same role as the grasshopper.
A primary consumer is mostly a herbivore. They feed directly on plant matter and convert them into useful nutrition for their own needs.
Grasshoppers feed on grasses. They are able to process plant matter into digestible food materials.Organisms of this kind are primary consumers. Organism such as Y are the secondary consumers. They feed on other organism but not directly on the plants.Answer:
A : X, because organism X has the same role as the grasshopper

Explanation:
The above are parts of a flower. The style actually holds up the stigma. It is the passage that leads down to the ovary which actually contains the ovules. Sepals are known to be green, leaf like structures which located at the base of a flower. It function is to protect the flower bud. An incomplete flower is known to be a flower that has "petals, sepals, stamens or pistils" missing. Perfect flowers are flowers that have the pistils and the stamen just in one flower.
