The image shows a rain forest ecosystem. The energy from plants, or producers, acts as the starting point of energy in the ecosystem. This energy is transferred to other organisms in the food web. In which two ways is the total amount of energy conserved in the ecosystem?
The organisms get some energy, while the remaining energy is discharged as thermal energy into the ecosystem. In an ecosystem, as we proceed up the trophic levels, we notice that the amount of energy keeps decreasing.
This phenomenon happens as a result of an ecosystem's inefficient energy transfer from one trophic level to another. The majority of the energy is discharged into the atmosphere as heat. It is known that around 10% of the energy in an ecosystem moves from one trophic level to another.
Thus, we can state that while the organisms receive some energy, the remainder enters the ecosystem as thermal energy. The amount of energy in an ecosystem decreases as we move up the trophic levels, as can be seen.

03. Select All Correct Statements Pertaining to the Dihydroxyacetone Phosphate Reaction Step in Glycolysis.
ATP is Needed to Generate Dihydroxyacetone Phosphate.
Fructose is Needed to Generate Dihydroxyacetone Phosphate.
Glucose-6-Phosphate is Needed to Generate Dihydroxyacetone Phosphate.
Inorganic Phosphate is Needed to Generate Dihydroxyacetone Phosphate.
None of the Statements are Correct.
-
In the process of conversion of dihydroxyacetone phosphate step in glycolysis, glucose-6-phosphate is needed to generate dihydroxyacetone phosphate. Thus, the correct option is C.
What is Glycolysis?Glycolysis is the process of formation of pyruvate from the catabolism of glucose molecule. This process produces ATP, NADP, and FADH₂ molecules.
Dihydroxyacetone phosphate (DHAP) reaction step involves the conversion of DHAP to glyceradehyde-3-phosphate (G3P) by the enzyme triose phosphate isomerase. This enzyme catalyzes isomerization of a three-carbon sugar into another three-carbon sugar (G3P).
Dihydroxyacetone phosphate lies in the glycolysis pathway, and is one of the two products formed by the breakdown of fructose-1,6-bisphosphate, along with glyceraldehyde-3-phosphate. It is rapidly and reversibly isomerized to glyceraldehyde-3-phosphate.
Therefore, the correct option is C.

Write a paragraph discussing the organs and substances involved in mechanical and chemical digestion.
Answer:
In the Digestive tract, the mouth is first on the list. This is where Mechanical digestion takes place. Teeth crush, grind, break, shred, and mash food into small pieces that are easy to swallow and digest. Saliva is an enzyme that starts to break carbohydrates if any. That's why the mouth also performs Chemical Digestion. Once the food is ready to be swallowed, it is pushed into the Pharynx and into the esophagus. The esophagus squeezes food with rhythmic muscle contractions-this is called Peristalsis. We have traveled in 3 out of the 8 organs in the digestive tract.

Are viruses prokaryotic?
Viruses are neither prokaryotic or eukaryotic.
Who are Prokaryotes?
Living things with only one cell lack an appropriate nucleus and other organelles.Examples include cyanobacteria, bacteria, and archaea.In prokaryotic cells, bacteria and archaea are present. They lack a nucleus that is contained within a membrane. Instead, it is kept in a floating nucleoid in the cytoplasm of the cell. Prokaryotic cells typically range in size from 0.1 to 5 m in diameter, making them smaller than eukaryotic cells on average. Although prokaryotes only have one cell, they can pair up or group together to form mats.Who are virus?
They are contagious organisms that reproduce within their hosts.They are neither alive nor dead.Because they depend on the host cell to perform their fundamental tasks, they are not alive (replication, transcription, translation).Typically, they lack a cell wall. DNA and RNA serve as the genetic material inside the capsid, which is a protective protein shell.Adenovirus, Hepatitis C virus, and other examples.Due to the lack of life, they are neither prokaryotes nor eukaryotes. They are unable to live and reproduce on their own.Hence viruses are not prokaryotes

Cellular respiration is a catabolic process which involves the oxidation of glucose molecules. It produces energy and is also responsible for increase in body temperature.
What is Cellular respiration?Cellular respiration is the process which involves the oxidation of glucose molecules in the mitochondria of cell. It results into formation of ATP molecules.
The first stage of cellular respiration occurs in the cytoplasm which is known as glycolysis. This is the step where glucose molecules are broken down into smaller molecules. A small amount of energy is also released in this process. The second stage occurs in the mitochondria of cell which is citric acid cycle. This is the step where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy. The third stage is known as Oxidative phosphorylation.

Independent variables (IV) always cause an effect on the dependent variables (DV) and on results. 1) IV: Light, DV: flowering patterns. 2) IV: Penicillin, DV: E. coli growth. 3) IV: Progesterone, DV: Ovulation.
What are dependent and independent variables?
While conducting an experiment, several variables might influence the results.
Independent variables are those in which the researcher is interested and wants to know its effect on another variable. These independent variables are the ones that influence other variables and the experiment results.
The dependent variable is the other one in which the researcher is interested. This is the one affected by the independent variable, so the researcher wants to know how it changes according to the changes of the independent variable.
Controlled or constant variables are all the remaining variables that might affect the results, but the researcher is not interested in their effect. To avoid their effect on the dependent variable, they must be constant.

What are some example of an animal organs? Plant organs?
Animals have organs including the stomach, liver, lungs, and heart. Plants have two different kinds of organs: stems and leaves. Organ systems are collections of organs in higher organisms.
Organ systems are a set of organs working together to maintain good biological performance; organisms are living creatures generated by an ordered collection of systems. Organs are a group of tissues that come together to form a complex structure with a special function. The vegetative and reproductive organs of plants can be distinguished. The root, stem, and leaf are vegetative plant parts, whereas the flower, seed, and fruit are reproductive. The reproductive organs are necessary for reproduction, but the vegetative organs are crucial for sustaining a plant's existence (they carry out key tasks like photosynthesis).

9. Is the condition in this pedigree inherited as a recessive or a dominant trait?
Answer: Recessive trait.
Explanation:
First generation:
In the first generation of the pedigree, the female is affected, while the male is not affected. Thus, the female must have at least one copy of the disease gene, while the male may or may not be a carrier.
Second generation:
They mate to give a normal female progeny. This female progeny has two X chromosomes, one from each parent. The female mates with a normal male and one of their sons are affected by the condition. This leads us to believe that the female was a carrier, and so was the male, and thus, the son has one affected gene from each parent, making him homozygous recessive for this condition.

Explain what are two factors that determine the thermal energy of a substance
The factors that determine the thermal energy of a substance are temperature and mass, which are associated to the number of particles (mass) and kinetic energy (temperature).
What is thermal energy?The term thermal energy makes reference to a type of kinetic energy in which the particles are in constant movement, in the opposite way than potential energy which makes reference to the storage of energy such as occurs in the chemical bonds of foods.
This type of energy (thermal energy) is associated with the relative movement of particles in a substance, i.e. its temperature, as well as the mass which depends on the number of particles that form the substance.
Therefore, with this data, we can see that thermal energy depends on both the temperature or relative movement of particles and also the mass of a given object, which is represented by the number of particles per unit of area.
