Explanation:
When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuous supply of NAD
Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.
In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as Glycolysis.
This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.

One of the hottest ideas in engineering today is the concept of building an energy capturing system
similar to photosynthesis. The system would use light energy to make artificial food. What two
parts would such a system need, and how must these parts interact if they are to be like
photosynthesis?
The capturing device and converter are the two parts needed by the energy capturing system in order to make food.
If an energy capturing system wants to perform the same function of photosynthesis, then it must have two parts i.e. converter and capturing device. The capturing device works to capture or absorb light energy and send it to the place where this energy energy is converted into food.
The second part is the converted which convert light energy into food particles. These two parts interact with each other then the desire product will e achieved otherwise not so we can conclude that capturing device and converter are the two parts needed by the energy capturing system in order to make food.

identify the explanations researchers suggested to explain differences in health and mortality by gender.
The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.
There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.
Amongst the many possibilities, scientists have mentioned:
Gender-reliant genetic vulnerability Hormonal factorsDifferences in physiologyas the main possible reasons.
Hormones play a big part in the health of each individual and are vastly different between genders, along with the endless differences in physiology at a molecular level. These factors together may explain why some members of a gender are more vulnerable to genetic illness.

Which of the following types of agriculture is most likely to use economies of scale?
Biodynamic
Conservation
Industrial
Slash-and-burn
Among the options listed, the most likely to use economies of scale (given our understanding of this concept) is Industrial Agriculture.
The concept of economies of scale is the idea that a business entity uses mass production of a product in order to be able to reduce the cost of every individual unit. This is a very common practice in industrial work environments.
Like most industrial work systems, Industrial Agriculture is focused on efficiency. The companies in question often use mass production as a method of reducing costs, given that by completing the process on a bigger scale, they can create more units of a product while sharing the same cost.
This system is the exact definition of the use of an economy of scale, therefore we can confirm that the Industrial Agriculture option is correct for the question at hand.

The transcription factor that binds directly to the tata-box sequence is TFIID. This transcription factor (TFIID) is a macromolecular protein complex.
The TATA box is a fundamental nucleotide gene sequence that forms the eukaryotic core promoters, which are required to initiate transcription.
TFIID is a macromolecular protein complex (also called the RNA polymerase II preinitiation complex), which acts as a general transcription factor during the initiation of eukaryotic transcription.
TFIID recognizes and binds to the TATA box (core promoter) and also binds with different activator and repressor proteins in order to regulate the transcriptional activity.

Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.
Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.
Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).
Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.
