Answer:
lipids
Explanation:
There are four major biological macromolecules in living systems viz: carbohydrate, proteins, lipids and nucleic acids. These macromolecules play a significant role in the optimal functioning of every living organism. Like every other polymer, these macromolecules are made up of simpler units called monomers that defines their chemical structure. In turn, the monomers consists of chains of chemical elements held together.
According to the question, Sebastian has colored balls that represents the elements contained by each of these macromolecules. The colored balls and the elements they represent are as follows: Red: hydrogen, Black: carbon, Purple: oxygen, and Green: nitrogen.
Lipids are structurally made up of fatty acids and glycerol, which are long chains of carbon and hydrogen elements with a relatively small percentage of oxygen in the structure. An example is palmitic acid, which has a structural formula: CH3(CH2)14COOH
Hence, Sebastian could make a LIPID macromolecule, which consists of long chains of red (hydrogen) and black (carbon) balls since lipids are mostly made up of carbon and hydrogen elements in their structure.
Carbohydrates are composed of more percentage of oxygen in their structure. Hence, a long chain of only red (hydrogen) and black (carbon) balls cannot make them. Proteins and nucleic acids are made up of additional nitrogen and phosphorus elements in their structure.
Answer:
B. Lipids
Explanation:
Lipids contain carbon and hydrogen.

Tree-dwelling primates have prehensile tails for gripping branches. Tree-dwelling opossums also have prehensile tails. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not. Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live. Hawaiian honeycreepers, with their elongated, nectar-sipping bills, all evolved from a finch-like ancestor.Answer and Explanation:
Tree-dwelling primates have prehensile tails for gripping branches. Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups. But we can also think about it as a common descent if we consider the farthest primates ancestor. Although still controversial, Plesidiapsi might be considered a common ancestor of primates, that evolved from a ree-dwelling mammal with a long tail. It is believed that this animal used to live in trees. Tree-dwelling opossums also have prehensile tails. Convergence. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Convergence. These are two groups that are very separated from each other, and they developed different traits according to their needs separately. Some of the species of these two groups adapted to feed on the same plant so they needed to develop the same characteristic to obtain nectar.Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not. Common descent . The common ancestor had a prehensile tail, some of the descendants developed the tail but some others did not.Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live.

Look at the DNA sequence (1st Picture) Which sequence shows a substitution mutation? (2nd Picture)
Also, can you explain how you got the correct answer?
Answer:
Sequence A
CGTTACTGCAAT to CGTGACTGCAAT
Explanation:
Mutation refers to any change, whether big or small, that occurs in the nucleotide sequence of a DNA/gene. This change can either be caused by replicational errors or induced by mutagens. Mutation can be of different types depending on the effects on the affected organism (mutant).
A substitution mutation is a kind of mutation in which one or more nucleotide base is replaced by another in a sequence. This is the case here as the
original sequence: CGTTACTGCAAT
Mutated sequence: CGTGACTGCAAT
The fourth base, T has been replaced by G in the upper strand of the DNA sequence.

What is the correct order of organization in animals?
A. Organ, organ system, cell, tissue, organism
B. Cell, tissue, organism, organ, organ system
C. Tissue, cell, organ, organ system, organism
D. Cell, tissue, organ, organ system, organism
The correct order of organization in animals is Cell, tissue, organ, organ system, organism—that is what is written in the option D. The cell is the first to form, followed by tissue, and finally organs and organ systems.
What is the organization of an animal?At the early stage, unicellular individuals were seen, and later, due to development, multicellular individuals were developed. The unicellular organism has only cells, then those cells unite to make a tissue, and in a tissue all the cells have the same function. An example is epithelial tissue, which is made up of many epithelial cells.
Tissues combine to form an organ, and organs combine to form an organ system. An example is an organ such as the liver that is made up of many tissues, but all tissues perform certain functions that are required for the liver, and in the same way, the organ system and the organism are developed.
Hence, the correct order of organization in animals is cell, tissue, organ, organ system, organism—that is what is written in the option D.

here are times where you will be provided with BUD dates. When you do not have access to the BUD dates, you will have to determine that date yourself. What is the appropriate BUD date for a water containing oral formulation? Not later than 14 days Not later than 30 days
Answer:
Explanation: Not later than 14 days.
Beyond Use Date (BUD) is the date after which a compounded sterile preparation may not be stored or transported. This time is calculated from the date of compounding, and it is different from expiration date. This is because the BUDs are assigned with a different approach from those applied to assigning expiration dates to manufactured drug products. Also, compounded preparations are intended for administration following short-term storage. So, the BUD is the date after which a compounded preparation shall not be used. A reliable BUD is established to ensure that the preparation has an accepted quality and purity at least until the labeled BUD.
BUD is calculated by:
Type of container in which it is packagedHow long the medication will be takenType of drugHow fast is the drug degradatedStorage conditionsDosage of the medicationNature of the drug and its degradation mechanism Potential for microbial proliferation in the preparationFor Nonaqueous Formulation, the BUD is not later than 6 months or the time remaining until the earliest expiration date of any API (Active pharmaceutical ingredient), whichever is earlier.
For Water-Containing Oral Formulation, the BUD is not later than 14 days when it is stored at controlled cold temperatures.
For Dermal and Mucosal Liquid, Semisolid Formulations/Water-Containing Topical, the BUD is not later than 30 days.

what are some non examples of hydroshere
The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

How might this possible mechanism affect the function of ATP synthase
Answer:
H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane
Explanation:
ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain
Answer:
a. Hypertonic solution
b. Hypotonic solution
Explanation:
There are basically 3 types of solutions in biology,
1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.
2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.
