Proteins are composed of a sequence of amino acids linearly arranged. To accomplish their functions thet must adopt different structures. Primary structure: Amino acid sequence. Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide. Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide. Quaternary structure: The aggregation of multiple polypeptide subunits.

Proteins are molecules composed of several amino acids.

Amino acids are monomers composed of

The R group is what differentiates one amino acid from another one.

Several amino acids linearly arranged and connected by peptidic bonds compose the polypeptide.

The peptidic bond is the union of two amino acids by their carboxyl and amine groups.

The R group of each amino acid stabilizes the molecule through their interactions.

The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.

Protein functions also depend on the amino acid sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.

The hydrophilic R-groups stay permanently in the molecule interior, avoiding interaction with water.

A set of genes arranged in a specific order for lactose processing is called a coli lac operon. When lactose is present, the lac operon, which consists of three genes termed lacZ that code for enzymes is active.

The regulatory gene lacI, which produces repressor proteins, the enzyme lac-galactosidase, lacY, which produces lactose permease, and lacA, which produces acetyltransferase. The repressor proteins bind to the operator protein and then control transcription. As soon as it attaches to the operator, transcription ceases.

The energy is related to the change of state represented by the model by: D. Atoms lose energy as a gas changes to a liquid.

A model of the transition from a gas to a liquid is shown in the accompanying image. It demonstrates how atoms or molecules change from being widely scattered as in a gas to being concentrated as in a liquid.

The atoms in this process move from a higher-energy state  to a lower-energy state releasing or losing energy in the process. The most common kind of energy loss is heat.

b. broad leaves to catch available light

c. vines and structures to climb towards sunlight

Explanation:

This because Adaptation refers to the ability of plants or animals to adapt, survive and reproduce in it's environment through its developed structural which help it to do so. Plants in the rainforest enjoy abundance of rain and there are thick forest of trees and shrubs. Therefore animals there normally have broad eyes to see in the darkness because the trees form shade easily. The plants normally have broad leaves to receive sunlight

Answer:

- broad leaves to catch available light

- vines and structures to climb towards sunlight

- large eyes to see in the darkness

Explanation:

Organisms that live in rainforests have adaptations that enable them to live in the different conditions that exist in each layer.

Global carbon emissions are still rising given that governments around the world are aware that these emissions need to drop because we need energy and the measures to avoid the use of carbon dioxide-generating energies are increasing.

The expression sustainable modes of energy production is used to denote all types of energies that are able to reduce or maintain the rates of carbon dioxide production worldwide such as solar energy.

Therefore, with this data, we can see that sustainable modes of energy production need to be produced in order to reduce carbon dioxide emissions.

Polymer of simple sugars carbohydrate are complex carbohydrates  and

a two-sugar polymer glucose is maltose .

Sugar molecules are joined together in long, complicated chains to form complex carbohydrates. Foods high in complex carbs include peas, beans, whole grains, and vegetables. In the body, both simple and complex carbohydrates are converted to glucose (blood sugar) and used as energy.

Glycogen, starch, and cellulose are all important glucose polymers for mammals. Cellulose's b-1,4 glycosidic connections prevent it from being degraded by constitutive enzymes.An oxide bond generated by the loss of a water molecule connects the two monosaccharides. The linking of two monosaccharide units via an oxygen atom is known as glyosidic linkage.

The presence of 83 colonies on the plate after incubation indicates that the original water sample contains about 830,000 cells per milliliter. The required number is option A.

Dilution is the process that helps to make the solution less concentrated. In microbiology, this helps to reduce the bacterial concentration so that it will be easier to count the colonies while plating.

Let T₁, T₂, T₃, and T₄ be the test tubes. The T₁ has a concentration of 10⁻¹ mL⁻¹, T₂=10⁻² mL⁻¹, and so on.

Let x be the number of colonies in an original water sample. Given that the T₄ has about 83 colonies per mL. And the concentration in T₄=10⁻⁴ mL⁻¹. Then,

\(\begin{aligned}\frac{\text{conc. of original water}}{\text{conc. of 4th dilution}}&=\frac{\text{colonies in original water}}{\text{colonies in 4th dilution}}\\\frac{1}{10^{-4}}&=\frac{x}{83}\\x&=83\times 10^4\end{aligned}\)

Then, the required number is 830,000 cells per milliliter. So the required option is A.

The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.

Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.

Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.

Hence, after many generations, puffins of species B and C will increase.

Additional sources of evidence together with genomics data are used to build a cladogram because there is info based on morphological, and embryological data that indicates homology.

Homology in evolution refers to the similarities between organisms that are due to common ancestry, i.e. the presence of shared characteristics between species that are attributed to the inheritance of similar structures from a common ancestor such as the front limbs of a human and a horse.

The use of Zoysia grass is likely to produce the benefit of reducing erosion on embankments. Option 4.

Zoysia grass is a plant with dense growth habits with an extensive root system, which makes it effective in preventing soil erosion.

When planted on embankments or slopes, Zoysia grass helps stabilize the soil by binding it together with its roots, thereby reducing the risk of erosion caused by water runoff.

The dense growth of Zoysia grass also helps to trap sediment and slow down the movement of water, further reducing erosion.

While Zoysia grass can offer other advantages such as weed control and providing green growth when Bermuda grass is dormant, its ability to reduce erosion on embankments is one of its notable benefits.

Glacial ice eroded the rock as it slowly flowed downhill. The accumulation of snow in frigid conditions such as arctic regions and high-altitude mountains produces glacial ice, a solid form of water. Snow accumulates weight over time, becoming solid ice that can flow under its own weight and destroy terrain.
