The evolutionary theorist says about the relatedness in organisms is due to molecular phylogeny, while the design theorist that group are related to each other by morphological characteristics.
What is the role of molecular phylogeny in evolutionary studies?The molecular phylogeny is the way to find out whether the species has a common ancestor or they are different. It is studied on the basis of DNA sequencing and amino acid sequence.
This is correct as it gives exact data of evolution. But previously the theorist believed and grouped organisms based on morphological character.
The similar-looking organism was grouped into the same category as an animal, plant fungus. Which is not the correct way.
Thus, evolutionary theorists rely on molecular basis study to know about the closeness of an organism to other species.

g B. PROTEINS 1. Name the gastric enzyme that initiates protein digestion. Explain how this enzyme is activated. Pepsin is the gastric enzyme that initiates protein digestion. It is activated by stomach acid into the active form. It then breaks down the protein in our food into smaller particles like peptide fragments and amino acids. 2. Name the ducts in the pathway by which pancreatic juice flows from the pancreas to the duodenum. The Pancreatic duct. 3. Describe 3 ways the body uses these amino acids..
Answers
Answer:
1-the gastric enzyme is pepsin, which is why it is a peptidase, since it catalyzes the binding of proteins within the stomach. Its activation method is the acidic pH of the stomach.
2-Pancreatic juice is a juice that hydrolyzes and helps the digestion of proteins or peptides, since this is the EXOCRINE substance of the pancreas, this juice being exocrine is poured into the main pancreatic duct of the pancreas and then through the choledochol in the blister of toilet at intestinal level.
3-amino acids are used by the body for hormonal, transport, and structural purposes. It also has other functions such as the conformation of the same DNA, but there are 3 that must be answered.
Explanation:
Proteins have structures or junctions that are quaternary, tertiary, binary, and primary.
the easiest to degrade with the quaternary and tertiary while the other two do not.
It is important that you know this fact why these structures are ordered from the outside to the inside or inside the protein, the outermost ones are the quaternary ones and the innermost ones are the primary ones.
A protein ceases to be protein and becomes free and separated amino acids when it reaches the heart of the protein and breaks the primary bond, or the sea the strongest and most difficult to break.
These amino acids have multiple functions but they can be said which, when united, are the unit that makes up proteins or peptides.

A student astronomer went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get smaller over time. Why did this happen?
Answers
Answer:
The light part of the Moon appeared to get smaller over time because of the change in the relative position of the Moon, the Sun, and the Earth. This is known as the lunar phase. The changing appearance of the Moon from the Earth's perspective is caused by the Moon's orbit around the Earth and the position of the Moon and Sun relative to the Earth. The Moon's phases are caused by the angle between the Moon, Earth, and Sun changing, as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, the side facing the Earth is not illuminated by sunlight, so it appears dark, and this is called a new moon. When the Moon is on the opposite side of the Earth from the Sun, the entire side of the Moon facing the Earth is illuminated by sunlight, so it appears full, and this is called a full moon. As the Moon moves in its orbit, the angle between the Sun, Earth, and Moon changes, causing the illuminated portion of the Moon visible from the Earth to change, leading to different lunar phases.
3. What evidence was provided for localized functions inherent to specific anatomical brain structures during execution of behavior and mental processes?
Answers
Evidence from studies of brain lesions and neuroimaging techniques supports the concept of localized functions in specific brain structures during the execution of behavior and mental processes.
There is substantial evidence supporting the localized functions of specific anatomical brain structures during the execution of behavior and mental processes. One such piece of evidence is the study of patients with brain lesions. By observing the behavioral and cognitive deficits resulting from damage to specific brain regions, researchers have been able to identify the functions associated with those areas. For example, damage to the prefrontal cortex can lead to impaired decision-making and planning abilities. Additionally, neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), have provided evidence for localized functions. These techniques allow researchers to observe changes in brain activity during specific tasks, providing insight into the regions involved in those tasks.For more questions on neuroimaging

characteristics of contaminated water
Answers
Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.
Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.
Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.
Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.
Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.
Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

Conservation of Mass Activity Worksheet
Instructions: Observe and analyze the interactions between the substances pictured in the slide show. Compare the properties of substances before and after each interaction. You will submit your completed worksheet for grading.
Data Table
On the table below, record your observations before and after the interactions and explain how mass was conserved. Describe the changes in properties that prove a chemical reaction occurred. The first row is an example.
Observations Before Interaction Observations After Interaction How was mass conserved? Proof of a Chemical Reaction
Example: Sugar + Heat The sugar is in tiny white particles in a pile. Heat is not seen but is implied by the heat source. The pile of sugar in the pot has a mass of 100 grams. There is a solid, light brown mass at the bottom of the pot. It has a mass of 100 grams. The mass of the sugar is the same in melted form as it is in solid crystal form. There was not a chemical reaction. Sugar did not change composition. It only melted. Melting point is a physical property, and this is a physical change.

HELPPPP PLEASEEEEEE
Answers
After Interaction How was mass conserved it is discussed below:
Steel Wool + Oxygen (Fire): chemical change
Egg + Heat: chemical change
Water + Heat: physical change.
Zinc + Hydrogen Chloride: chemical change
Sodium Hydroxide + Copper Sulfate: physical change
What is conservation of mass?According to the rule of conservation of mass, no atoms are lost or created during a chemical process. Instead, the atoms combine in various ways to generate products. This is why the number of atoms in each element in a balanced symbol equation is the same on both sides of the equation.
Steel Wool + Oxygen (Fire):The steel wool is a grayish color and has a rough surface. Oxygen is transparent It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder Well Iron oxide is 7 grams and steel wool combined is 7 grams so that the mass was conserved Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.
Egg + Heat:The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white It was conserved because the eggshell was 4 grams and the fried egg is 41 grams It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.
Water (H₂O) + Heat:The water is a clear liquid, while the heat is very hot but transparent The water turned into a type of oxygen -Water Vapor- If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor. There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition. So, it is a physical change.
Zinc (Zn) + Hydrogen Chloride (HCl):Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas. The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid. Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left. When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid. So, it is a chemical change.
Sodium Hydroxide + Copper Sulfate-Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved. The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate. So, it is physical change.
