Answer:
combine with each other using covalent bonds
Explanation:
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
Answer:
Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct. Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.
Why must the number and type of atoms be the same in the products of a chemical reaction as in the reactants?

the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.
side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)
a)
Actual diameter = 0.007 mm
Diameter of scaled diagram = 2.3 cm = 23 mm
Formula to use:
Magnification = scaled dimension/actual dimension
Magnification = 23/0.007
Magnification = 3285.714... → x3286
b)
Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose
c)
i.
RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs
ii.
RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;
The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;
The small size also helps in being able to circulate the vasculature effectively and successfully

Which organism carries out autotrophic nutrition
Answer:
Autotrophs is the answer
Example : plants
Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.
Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.
Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

Is the cholesterol molecule mostly polar or mostly nonpolar?
Answer:
Most of the cholesterol molecule in non-polar and therefore associations with the non-polar fatty acid tails of the phospholipids. However, the hydroxyl group (-OH) on cholesterol carries a negative charge and therefore associates with the polar environment of water either inside the cell or outside.
Explanation:

how will you explain the importance of it in completeness of the biological organization?
The importance of biological organization is that it allows the study of natural balance between all organisms in a simple way.
The biological organization is a biological term that refers to the hierarchy of complex biological structures and systems that define life through a reductionist approach.
In this form of organization, the traditional hierarchy begins in the atom, this being the lowest level, and ends in the biosphere as a superior system.
The integrality of this organization focuses on the reciprocal relationships between each level, because the higher levels are more complex, but contain each of the organisms and parts that make up the lower levels. This type of organization must be understood as a whole.

The independent variable would be us humans polutling the ocean with oil and other plastics destroying the coral reefs. The dependant variable is an abbrasive species of fish becoming overpopulated and killing all the fish that help the coral grow causing the coral to die.

where are unmyelinated nerve fibers surrounded by schwann cells?
Schwann cells without myelination are seen in the peripheral nervous system (PNS).
Myelinating Schwann cells and non-myelinating Schwann cells are the two different kinds of Schwann cells. One kind of neuroglial cell is the Schwann cell. Nerves are helped and supported by neuroglial cells. Nerve impulses can be sent at speeds of about 270 miles per hour thanks to the ability of Schwann cells to speed up the process.The myelinating Schwann cell coils around nerve axons with large diameters. The myelinating Schwann cell creates the neurilemma, a lipid base membrane, as it loops itself around the nerve fiber. The myelin sheath develops from the neurilemma.However, unlike a hotdog bun that encircles a hotdog, the non-myelinating Schwann cell does not form myelin; instead, it permits thin nerve fibers to rest along, within, and on top of the non-myelinating Schwann cell. Non-myelinated nerves often have slower nerve transmission.Learn more about the Schwann cells with the help of the given link:

What type or piece of material culture do you think gives the most information about your society? Why?
This is a question on the circulatory system. I don't understand how the pathway that the blood goes through in the heart makes it oxygenated. Could someone pleas explain to me what each part does and how when it goes to the lungs it gets oxygenated?
Answer:
deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.

The results suggest the optimum temperature for the enzyme is between which two values?
A 15 °C and 35 °C B
35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C
Answer:D
Explanation:
The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.
What is an optimum temperature for enzyme?Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.
The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.

The diagram below represents two cells viewed using the same magnification with the same microscope. One possible conclusion that can be drawn about the activity of these two cells is that...
Answer:
more active transport occurs in cell A then cell B
Explanation:
hope this helps ;)
The possible conclusion that can be made drawn about the activity of these two cells is that more active transport occurs in cell A than in cell B. The correct option is B.
What is transport?Active transport is a type of transport that cells use to move molecules up and down cell membrane concentration gradients.
Moving actively is carried out using a variety of membrane proteins known as carrier proteins that are connected to an energy source, such as ATP, for example.
The energy needed to move molecules or ions up or down a concentration gradient is provided by the hydrolysis of ATP during this process, known as active transport. The other transport is passive transport, which is reverse.
Therefore, the correct option is B. more active transport occurs in cell A than in cell B.
