discuss the chemical structure; (b) describe how small component parts are assembled to make larger macromolecules using condensation reactions, and (c) describe how large molecules are broken down into their component parts via hydrolysis.
Answers
(a) Chemical structure refers to the arrangement and bonding of atoms in a molecule. It determines the molecule's physical and chemical properties.
It is represented by molecular formulas, structural formulas, or diagrams like ball-and-stick or space-filling models. (b) Small component parts are joined to form larger macromolecules through condensation reactions. In this process, two molecules combine, releasing a small molecule like water or alcohol as a byproduct. The small components, called monomers, link together by forming covalent bonds. This repetitive bonding creates polymers with specific structures and properties, such as proteins, nucleic acids, and carbohydrates. (c) Large molecules can be broken down into their component parts through hydrolysis. Hydrolysis involves the addition of water molecules to break the covalent bonds in the macromolecule. This reaction reverses the process of condensation. By adding water, the polymer is cleaved into smaller units, or monomers, which can be utilized for energy or building new molecules. Hydrolysis is a vital process in digestion, where enzymes break down complex molecules into simpler forms for absorption and use in the body.

Answers
A transform boundary occurs when two tectonic plates slide past each other horizontally. A horizontal or sideways motion typically characterizes the movement. Transform boundaries often create transform faults, where the plates grind against each other. These boundaries are associated with earthquakes due to accumulated stress being released along the fault line.
A divergent boundary occurs when two tectonic plates move away from each other. As the plates separate, molten rock, or magma, rises from the mantle to fill the gap, creating a new crust. Divergent boundaries are typically found along mid-ocean ridges or rift valleys on land. They are associated with volcanic activity, earthquakes, and the formation of new crusts.
A convergent boundary occurs when two tectonic plates collide or move toward each other. There are three types of convergent boundaries, depending on the types of plates involved:
a. Oceanic-Oceanic Convergent Boundary: When two oceanic plates collide, one plate is usually subducted (forced beneath) the other due to its denser nature. This subduction zone often leads to the formation of volcanic arcs, trenches, and island arcs.
b. Oceanic-Continental Convergent Boundary: When an oceanic plate collides with a continental plate, the denser oceanic plate is typically subducted beneath the continental plate. This subduction can create mountain ranges, volcanic activity, and deep-sea trenches.
c. Continental-Continental Convergent Boundary: When two continental plates collide, neither plate subducts due to their similar densities. The collision often leads to the formation of large mountain ranges with intense folding and faulting.

Answers
When looking at a somatic diploid cell in G2 and seeing that there are 36 chromosomes present, there will be 18 pairs of homologous chromosomes.
What is a somatic diploid cell?Somatic cells are cells that make up the body of an organism that are not used for sexual reproduction. A diploid cell is a cell that has two sets of chromosomes. Each set has 23 chromosomes, and the diploid cell contains 46 chromosomes total. A pair of homologous chromosomes refers to two chromosomes with the same size, shape, and set of genes.The cell cycle is a process that occurs in cells. It consists of various stages, each with its specific characteristics. The cell cycle can be divided into two main stages: interphase and the mitotic phase.
Interphase is the period in which cells prepare for division. G1, S, and G2 are the three phases of interphase. During G1, cells grow and develop. DNA replication occurs in S phase, and cells prepare for mitosis in G2 phase. Mitosis, which is the second stage, is where cells divide to produce two daughter cells. The daughter cells are genetically identical to the parent cell, and each daughter cell receives a set of chromosomes.

The population of birds with large beaks will increase on the island (1st listed) ; The trait for large beaks will be passed on to future generations through natural selection. (3rd listed)
B) 80 /200
Explanation:
Giraffes evolved over many generations to have long necks. Giraffes that had longer necks were more likely to survive than giraffes with shorter necks because they had better access to food. This is an example of natural selection / survival of the fittest.
(the "fittest" [most beneficial/practical] trait is surviving and getting "selected" by nature)
Giraffes are also vertebrates, like humans. In fact, despite their different neck sizes, humans and giraffes have exactly seven vertebrae bones in their neck. This similarity suggests human and giraffe necks are homologous [structures]

...' What are two ways the decrease in seed availability will affect the population of birds on the island?'
The population of birds with large beaks will increase on the island.
[This is the concept of natural selection / survival of the fittest, they have the most abundant resource [because they are able to eat what is abundant on the island, compared to smaller birds that have a larger decrease in food availability] ]
The trait for large beaks will be passed on to future generations through natural selection.
[If these birds / and this trait survive, they will be able to have offspring [future generations]. Birds with a low survival percentage will be less successful in mating, and will likely not produce the same quantity of offspring that will carry on their traits to future generations.]

frequency of an allele:
population: 100
frequency recessive [homozygous bc 2 same recessive alleles]: 25 (tt)
frequency dominant homozygous: 45 (TT)
frequency heterozygous dominant: 30 (Tt)
total alleles: 100 [our population] times 2
100 · 2 = 200
total alleles: 200
number of times we have [dominant] T:
30 from each heterozygous dominant (Tt)
2 · 45 (TT has two T's) = 90 from homozygous dominant
30 + 90 = 120
number of times we have [recessive] t :
30 from each heterozygous dominant (Tt)
2 · 25 (tt has two t's) = 50 from each homozygous recessive
30 + 50 = 80
So, we know that the frequency of recessive allele [t] is 80 / 200
[80 out of 200]
So, option B) 80 / 200 is correct
(this = 0.4)
(and dominant [T] is 120 / 200; I say this to show that recessive frequency and dominant frequency are calculated the same way!!)

Answers
-Earth is on an axis, which means it roared
-some of the earth is facing the sun, hence summer and spring
-some of the earth is facing away from the sun, hence fall and winter.
-spring and fall are unique because the axis of earth is 90 degrees away from the sun during those seasons
Paragraph 2:
-once again it is due to the earth being in a axis
-the uneven heating of earth creates global circulation patterns
-Global circulation patters cause the different temperatures and storms
-add this example: since the poles are usually faced away from the sun at almost all times, there is barely any weather patterns. The poles are known for being “cold deserts” because they don’t have much precipitation or storms.
Paragraph 3:
-Different climates are due to the earth being on an axis
-different parts of the earth get sun more, and other parts don’t
-the sun isn’t evenly distributed amongst the different parts of the earth. As a result (what I said above)
-I’m places such as the tropical rainforest (near the equator) is wet and humid. It gets a lot of sun since it is in the middle of the globe.
-the middle of the globe gets a lot of sun compared to the other parts

Composite volcanoes are tall, steep cones that produce explosive eruptions.
Shield volcanoes form very large, gently sloped mounds from effusive eruptions.
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

Most phenotypic traits—features of the organism that we can observe—are not easy to put into a Punnet Square. Give at least two reasons, or factors, that make most phenotypic traits complicated. How, then, can we measure these traits?
Answers
Most phenotypic traits are complex due to polygenic inheritance and environmental influences.
Phenotypic traits often result from the combined effects of multiple genes (polygenic inheritance) and can be influenced by environmental factors. Punnett Squares, which illustrate single gene pair inheritance, are not suitable for capturing the complexity of such traits. Additionally, environmental factors can interact with genetic factors, leading to variations in trait expression.
To measure complex phenotypic traits, alternative approaches are used. Quantitative measurements, such as height or weight, provide precise numerical values. Statistical analysis helps identify patterns, correlations, and heritability estimates in populations. It involves studying large sample sizes and employing statistical models to understand the contributions of genetic and environmental factors. Molecular genetics advancements have further enhanced our ability to study complex traits at the genetic level.

1. list the energy sources used to synthesize atp for muscle contraction.
Answers
ATP or Adenosine Triphosphate is the primary source of energy for most cellular processes including muscle contraction. ATP is synthesized through several energy sources during muscle contraction.
The sources of energy that synthesize ATP for muscle contraction are as follows:Glycolysis: This process occurs in the cytoplasm and it converts glucose or glycogen into pyruvate. The energy released in this process is used to synthesize ATP. The net gain from glycolysis is two ATP molecules. Krebs cycle or Citric acid cycle: This cycle occurs in the mitochondria and it generates ATP by oxidizing acetyl-CoA to carbon dioxide. The total yield of ATP from one glucose molecule is 36 or 38 ATP molecules depending on the source of glucose. Electron transport chain: This is the final stage of oxidative metabolism that occurs in the inner membrane of mitochondria. During this process, electrons are transferred from one molecule to another and this generates a proton gradient. This gradient is used by ATP synthase to synthesize ATP from ADP and inorganic phosphate (Pi). The yield of ATP from one glucose molecule in this process is 28 or 32 ATP molecules depending on the source of glucose.
