What's the waste product of electrons and pyruvate combining in fermentation?
Answer:
Lactate
Explanation:
Under the conditions of oxygen scarcity, pyruvate does not enter the Kreb's cycle in the form of acetyl CoA. Rather pyruvate is reduced into lactate by accepting the electrons from NADH. Reduction of pyruvate and oxidation of NADH form lactate and NAD+. The process is called lactic acid fermentation.
Here, the NAD+ enter the glycolysis to continue the energy production while lactate is a waste product.

Alcohol builds up in the bloodstream after a person consumes more than how many drinks per hour? 1 2 3 4
Answer:
Option B, 2
Explanation:
As per the standard rule if a person taken one drink per hour then he/she gets enough time to burn off the alcohol consumed irrespective of number of drinks taken at the same rate. Hence, there is no accumulation of alcohol in the body.
However, if a person intakes more than one drink per hour then alcohol starts building/accumulating with in the blood stream. After consuming 2 drinks per hour , one is dissolved but the other one accumulates.
Hence, option B is correct.
The human body can metabolize approximately one standard drink per hour. Consuming more than this causes alcohol to build up in the bloodstream, with potential negative effects such as reduced reaction times and lowered alertness. Factors such as body weight, genetics, and consumption rate can affect how quickly alcohol is metabolized.
Explanation:Alcohol is metabolized and removed from the body at a certain rate; this rate slightly varies between individuals, typically being slower in women compared to men. On average, the human body can metabolize approximately one standard drink per hour. Drinking more than this will cause alcohol to build up in the bloodstream, resulting in higher blood alcohol concentrations. Consider that factors such as body weight, genetics, and consumption rate may also affect how quickly one can metabolize alcohol.
Drinking more than the body can metabolize can lead to riskier effects. Some effects of consuming a large quantity of alcohol include decrease in visual acuity, slow reaction times, lowered alertness, and loss of behavioural control. Excessive consumption can result in complete loss of consciousness and in some cases, can lead to health problems such as Fetal Alcohol Spectrum Disorder (FASD) in infants if consumed by a pregnant woman.
It's important to be aware of one's own drinking habits and the potential effects. Practicing moderation and understanding the body's limits when it comes to alcohol can help promote healthier and safer behaviour.

Answer:
B; height
Explanation:
Traits are polygenic when there is a wide variation in the trait.
The polygenic trait in humans is option B. height.
What is a polygenic trait in humans?Polygenic traits are traits that are controlled by multiple genes instead of just one. The genes that control them may be located near each other or even on separate chromosomes. Because multiple genes are involved, polygenic traits do not follow Mendel’s pattern of inheritance. Instead of being measured discretely, they are often represented as a range of continuous variation.Some examples of polygenic traits are height, skin color, eye color, and hair color.HeightHuman height is controlled by many genes, in fact, there are over 400 genes related to height, and all of these genes interact to make up a person’s phenotype.

Which of the following best describes the Expensive Tissue Hypothesis? brains require more energy, so the gut had to be reduced, and larger brains and tool use led to higher quality diets. increasing body size means that Homo neanderthalensis had to include more fat in its diet. brains require more energy, so the gut had to be reduced as brains got bigger. brains require more fat, so the gastrointestinal viscera (gut) had to expand, and hands were needed to acquire more food.
Answer:
The correct option is this: BRAIN REQUIRES MORE ENERGY, SO THE GUT HAD TO BE REDUCED AND LARGER BRAINS AND TOOL USED LED TO HIGHER QUALITY DIETS.
Explanation:
The Expensive Tissue Hypothesis is an hypothesis that relates the relationship between the brain and the gut during the period of human evolution. The hypothesis submits that in order for human to develop a larger brain without increasing his metabolic rate, he has to use less energy on other expensive tissues such as gut. Thus, the hypothesis suggests that human evolve a larger brain and make up for this development by evolving a gut that need less energy and by eating higher quality foods that are obtained by mean of using agricultural tools.
