Answers
Metabolism refers to the sum total of all the chemical reactions that occur in organisms.
In the life processes of an organism, there are many chemical reactions that happen in the body that require energy. The sum of all of these reactions is referred to as metabolism. It involves breaking down complex molecules into simpler ones and also building complex molecules from simple ones.
Metabolism is responsible for the maintenance of the living state of an organism and all cellular processes of the body. Metabolism can be grouped into two categories: catabolism and anabolism. Catabolism breaks down complex molecules into simpler ones and releases energy in the process while anabolism uses energy and simple molecules to build complex molecules. An example of catabolism is the breakdown of glucose to release energy while an example of anabolism is the synthesis of proteins from amino acids.
Metabolism is important because it is responsible for the production of energy in the body, the breakdown and synthesis of molecules, and the elimination of waste. In summary, metabolism can be defined as the sum total of all the chemical reactions that occur in organisms, and it is a vital process that is responsible for sustaining life in an organism.

Explanation:
Judging from the pictures, I think to claim that lungfish are “more closely related to the tetrapods than… to tuna” is an extraordinary claim.
2. According to some this would imply it needs extraordinary evidence.
3. Evidence based on a particular assumption only shifts the focus of the argument to the justifiability of the assumption.
4. If you insist that the world had no designer and OOL happened by chance ( a very shaky assumption that no one has shown to be in line with any reasonable calculation of the probabilities involved ) then there exists extraordinary evidence that the lungfish is closer because of the function of lungs. However, this is only sufficient evidence, it is not necessarily evidenced. the same situation is likely to have occurred given the assumption of design
5. So we are back to all evidence being subject to a basic assumption that do you (by faith ) believe that creation happened without an intelligent designer… and I do not.
6. Your basis for believing that lungfish are closer related to humans than tuna ( even in a narrow technical sense ) is a statement of faith.

Answers
Mitochondria are cellular organelles that are involved in cellular respiration, which generates adenosine triphosphate (ATP).
ATP is responsible for the body's energy production, which is required for different metabolic functions. A lack of mitochondria would result in a significant impact on the body's metabolic processes.If all your mitochondria were destroyed, you would have much less ATP available to think, move muscles, etc. Metabolically, ATP is essential for the body's metabolic activities. ATP is produced via oxidative phosphorylation, which occurs in the mitochondria. Hence, if the mitochondria are destroyed, the body cannot produce ATP via oxidative phosphorylation, leading to an insufficient ATP supply. As a result, the body's metabolic processes will significantly slow down or stop.
Additionally, you would have much less oxygen available to think, move muscles, etc. Mitochondria are responsible for oxygen utilization in cellular respiration. If the mitochondria are destroyed, oxygen is not effectively used. Hence, less oxygen would be available to think, move muscles, etc.
Furthermore, you would have much less glucose available to think, move muscles, etc. Mitochondria are involved in the process of breaking down glucose during cellular respiration to produce ATP. If mitochondria are destroyed, glucose breakdown would be significantly reduced, leading to lower levels of ATP production. This would result in a lack of glucose available for the body's metabolic activities.
Therefore, a lack of mitochondria would have a considerable impact on the body's metabolic processes, leading to a shortage of ATP, oxygen, and glucose supply.

A researcher finds an embryo of an unknown animal. By which measure could she determine whether the organism is a protostome or deuterostome
Answers
A researcher found the fetus of an unknown animal. By measuring the number of germ layers in an embryo it can be determined whether an organism is a protostome or a deuterostome. Here option B is correct.
The measure that could be used to determine whether an unknown embryo is a protostome or deuterostome is the number of germ layers in the embryo. This is because protostomes and deuterostomes have different patterns of embryonic development, which are reflected in the number of germ layers they possess.
Protostomes typically have three germ layers: the ectoderm, mesoderm, and endoderm. Deuterostomes, on the other hand, have four germ layers: the ectoderm, endoderm, mesoderm, and an additional layer called the archenteron.
During embryonic development in protostomes, the blastopore (the opening of the developing digestive system) develops into the mouth, while in deuterostomes, it develops into the anus. This difference in development is reflected in the number of germ layers, with deuterostomes having an additional layer that gives rise to the lining of the digestive tract.

what enzyme is responsible for splitting the two strands?
Answers
The enzyme responsible for splitting the two strands of DNA is called helicase.
It unwinds the double helix by breaking the hydrogen bonds between the base pairs, separating the two strands. Helicase is a type of enzyme that is essential for DNA replication, the process by which cells create a copy of their genetic material before cell division.
It is responsible for unwinding the double helix structure of DNA, which is necessary for the replication machinery to access the individual strands and create a new complementary strand. The process of helicase unwinding the double helix is called DNA melting.
Helicase uses the energy from ATP hydrolysis to unwind the DNA, and it requires the assistance of other enzymes such as single-strand binding proteins (SSBs) to stabilize the unwound regions.

DNA replication is the process by which cells copy their genetic material before cell division. One of the key enzymes involved in this process is DNA helicase, which is responsible for separating the two strands of DNA in a helix so that they can be copied.
According to DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. DNA helicase unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing the strands to separate. It confirms that during replication, the two DNA strands separate at multiple points along the length of the chromosome. The separation of the two strands is a necessary first step for the replication process to proceed, and helicase is the enzyme responsible for this separation.

A pig breeder wants to select for two traits: Weight and Feed intake. They have decided that they wish to increase weight whilst reducing feed intake. Both traits have the same heritability (0.3) and the same phenotypic standard deviation (2 units). The genetic correlation is 0.40 and the phenotypic correlation 0.30. The breeder has calculated the economic value on the two traits of +2 for weight and -0.5 for feed intake.
A selection index based on own performance is calculated and used to predict response to selection in one generation, which is 1.05 Kg for Weight and 0.25 Kg for Feed intake. The breeder has asked you a series of questions regarding the results.
A. What is a selection index used for in animal breeding?
B. What is the difference between economic values and predicted response? C. Are the economic weights appropriate for the breeder’s goal? Explain why the response for feed intake is positive.
D. Explain how an index could be designed such that there was no response for feed intake.
Answers
The selection index based on own performance is a useful tool for evaluating the potential response to selection for multiple traits.
A) A selection index is a technique used in animal breeding to identify the best breeding animals based on a selection of traits. This index is used to estimate the breeding value of an animal in a breeding program.
B) Economic values are used to assign relative economic importance to different traits in a breeding program. The predicted response, on the other hand, is the expected improvement in a trait due to selection for that trait. It is calculated by multiplying the selection differential by the heritability.
C) The economic weights are appropriate for the breeder’s goal since they reflect the breeder’s desire to increase weight while decreasing feed intake. A positive response for feed intake may be due to the genetic correlation between the two traits. Since the genetic correlation between weight and feed intake is positive, selection for weight will indirectly lead to an increase in feed intake.
D) To design an index such that there was no response for feed intake, the index would need to be designed so that it only selects animals based on their weight and not their feed intake. This would involve assigning a weight of zero to feed intake in the selection index. This would mean that only animals with the highest weight would be selected, regardless of their feed intake.
However, the economic weights used in the index should be appropriate for the breeder’s goal in order to maximize the desired response. In this case, the positive response for weight suggests that the economic weights used are appropriate, but the negative response for feed intake suggests that a different design may be necessary to achieve the breeder’s goal of increasing weight while reducing feed intake.

A. remote, episodic memories
B. remote, semantic memories
C. remote procedural memories
D. state-dependent memories
Answers
According to the multiple trace hypothesis, the hippocampus is involved in retrieval of remote, episodic memories.
The multiple trace hypothesis is a theory that the hippocampus is involved in retrieving all types of memories, not only episodic ones. The multiple trace hypothesis proposes that the hippocampus is involved in retrieving a wide range of memories, including episodic memories, semantic memories, and spatial memories, among others. Furthermore, it asserts that the hippocampus is involved in the retrieval of both recent and remote memories. It is well-known that the hippocampus is required for the formation of new memories, especially episodic memories, which are memories of specific events that include information about when and where they occurred. According to the multiple trace hypothesis, the hippocampus remains involved in the retrieval of episodic memories even after they have become remote, or distant in time, from their initial encoding. In other words, the hippocampus is believed to continue to play a role in retrieving these memories, not just in their initial formation. However, it is important to note that the multiple trace hypothesis does not suggest that the hippocampus is the only brain region involved in memory retrieval.
Thus, according to the multiple trace hypothesis, the hippocampus is involved in the retrieval of remote, episodic memories.

D) Some plants are in environments in which sunlight is constant.
Answers
Some plants will be placed in complete darkness and some will be placed where sunlight is constant. So the correct option is C and D.
What is the effect of sunlight on plant growth?
Carbon dioxide from the atmosphere is absorbed by plant leaves, while water is absorbed by roots. The energy plants require to transform carbon dioxide and water into carbohydrates and oxygen is provided by sunlight. In order to enhance crop biomass and support vegetative and reproductive development, photosynthesis produces carbohydrates. Photosynthesis can only take place in the daylight since it requires sun energy.
The quantity of water vapor present in the atmosphere has an influence on the quantity of solar energy that reaches a crop. By reflecting solar radiation back into space and keeping it from reaching crops, clouds limit solar radiation. Future cloud cover will gradually decrease as the number of greenhouse gases in the atmosphere rises, which will contribute to greater global warming.
