Answers
A multicellular organism is made up of numerous cells that cooperate, whereas a unicellular organism only contains one cell. Each function must be managed by a single cell, whereas in multicellular organisms.
What is in a unicellular organism?Any living creature only with one cell, which performs all crucial body functions like metabolism, waste, and fertilization, is referred to as a "unicellular organism." Unicellular organisms can either be prokaryotes or eukaryotes. Unicellular organisms include bacteria, archaea, unicellular fungi, and unicellular protists.
How is it important to unicellular organisms?Cell division in unicellular organisms is crucial only for reproduction. They divide their cells through a process called mitosis to create their daughter cells. Cell division is crucial for the development of new cells and reproduction in multicellular animals.

Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that aid in: Dissect food. Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine, and arginine are the 12 amino acids.The body cannot naturally generate essential amino acids; therefore we must get them from the foods we eat. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids. Compared to other foods, bananas do have a lot of seven of the nine essential amino acids. Banana lacks a little isoleucine and methionine.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.
Answers
During volume changes in the thoracic cavity, Diaphragm is primarily responsible for changes in length.
The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.
The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.
Thus, diaphragm is responsible for the increase in length of the thoracic cavity.

The Volley principle was given by Weaver, gray and their research team in 1937. According to this principle,
Whenever someone is exposed to high frequency sounds (i.e. succession of stimuli) very frequently, the Corti of ear merges all the stimuli and form a volley.
This causes successive volleys of impulses and these volleys are fired such to align with inputs of stimuli. This helps neuron process and fire for each sound event.

175,000 kcal/m2/yr , and the plant respiration is estimated to be 115,000kcal/m2/yr . what is the total amount of energy transferred during photosynthesis for this ecosystem?
Answers
The total energy exchanged during photosynthesis for this environment is 290,000 cal/m2/yr.
The term "net primary productivity" refers to the amount of energy retained by an environment's biomass when energy is released for metabolism and maintenance. Net primary productivity, as opposed to gross primary productivity, refers to the total energy input into the ecosystem before taking into account energy loss.
Net primary productivity (NPP) is calculated mathematically as Gross Primary Productivity (GPP) - Respiration.
NPP = 175,000 cal/m2/yr for the pine forest, and respiration = 115,000 cal/m2/yr, hence GPP = 175,000 + 115,000 = 290,000 cal/m2/yr.
Therefore, 290,000 cal/m2/yr of energy is transported throughout photosynthesis for the environment as a whole.

At this stage there will be capture of CO₂ from the free air and then the union of CO₂ with ribulose bisphosphate which is assisted by the rubisco enzyme.The photosynthesis cycle that occurs when it is dark or does not require sunlight in the process is called the dark reaction or Calvin cycle. And in the process it uses ATP and NADPH² that have been produced in the daytime photosynthesis process.In the Calvin cycle, glucose is formed through a chemical reaction that converts oxygen (CO₂) and several other components into glyceraldehyde 3-phosphate.The Calvin cycle is very useful in life, because it is the main player in the process that provides oxygen stability and prepares plant raw materials to make starch that we can later use.Learn more about Calvin cycle here: brainly.com/question/13477893

Closest to the definition of primary production is the production by primary producers in the deep parts of the ocean. So the correct option is b.
Primary production in ecology is the synthesis of organic molecules from aqueous or atmospheric carbon dioxide.
Primary production refers to the process by which autotrophs assimilate and fix inorganic carbon and other inorganic nutrients into organic matter. The chemical energy source is typically ignored when estimating an ecosystem's primary production.
There are two forms of primary production: gross primary production, which measures the total amount of organic material generated by all producers in an ecosystem.

what is the physical explanation for the very slow movement of membrane phospholipids from one leaflet of a biological membrane to the other? what factors influence this rate?
Answers
The physical explanation for the very slow movement of membrane phospholipids from one leaflet of a biological membrane to the other is the polar head must cross the hydrophobic area of the phospholipid membrane in order to go from one side to the other.
It takes a lot of energy to complete this process, which makes it go slowly. Last but not least, phospholipids have the ability to "flip-flop" between the two leaflets of the bilayer in a transverse motion. The phospholipids in the lipid bilayer can move either radially, laterally, or transversely between the bilayers. The monolayer (also known as a leaflet) on one side of a synthetic bilayer extremely seldom migrates to the other. Less frequently than once per month, each molecule experiences this "flip-flop" process.

Answers
Of the factors that influence diffusion of respiratory gases, the most variable and, therefore, important factor to consider is the concentration gradient.
The exchange of gases like oxygen and carbon dioxide occurs mostly based on pressure or concentration gradients in the primary sites of gaseous exchange in the lungs, known as alveoli. Diffusion coefficient of the gases and pressure difference across the membrane also play a vital role in diffusion.
Other significant variables that can impact the pace of diffusion include the solubility of gases and the thickness of the membranes engaged in diffusion. As oxygen and carbon dioxide do not react in the alveoli, the reactivity of gases has no impact on the rate of alveolar diffusion.

Answers
A strong correlation between independent and dependent variables is indicated by a coefficient of correlation of 0.85.
What type of correlation is this?Correlation coefficients serve as measures of how strongly two variables are related linearly. Positive relationships are shown by correlation coefficients greater than zero. A value less than zero denotes an negative association. Lastly, a value of 0 denotes that there is no correlation between the two variables, x and y.
On dividing the covariance by the sum of the standard deviations of the two variables, one may calculate the correlation coefficient. Here, the given correlation value of the data is 0.85. So, the more severe (closer to -1 or 1) the correlation coefficient, the stronger the association. This also signifies that a correlation that is close to zero denotes the independence of the two variables, i.e., that neither variable tends to drop nor rise as the other does.
