during anaerobic metabolism in red blood cells, the carbons of glucose end up in a. co2. b. ethanol. c. lactic acid. d. both co2 and ethanol. e. all of the above.
Answers
C. Latic Acid, Pyruvate is designated as the pathway's end product under aerobic conditions, while lactate is the end product under anaerobic conditions. A base deficit results from the reaction between lactic acid and bicarbonate, which lowers serum bicarbonate levels.
When regular, oxygen-using (aerobic) cellular respiration is not possible, that is, when oxygen is not present to act as an acceptor at the end of the electron transport chain, both of these processes are made possible via alternate glucose breakdown routes. These routes for fermentation are essentially extensions of glycolysis with a few more processes. While the extra reactions in your muscles produce lactic acid, the extra reactions in yeast produce alcohol.
Although fermentation is a common process, it is not the only technique to anaerobically obtain energy from fuels (in the absence of oxygen). As a substitute for O2, some living systems use an inorganic molecule like sulfate as the last electron acceptor in an electron transport chain. Some bacteria and archaea carry out this procedure, which is referred to as anaerobic cellular respiration.

Relative dating places fossils into a sequence of events without assigning a specific age.
Relative dating is used to order geological events and the rocks they leave behind. Stratigraphy is the process of interpreting the order (layers of rock are called strata). Relative dating does not yield precise numerical dates for the rocks.
Relative dating involves placing fossils in a sequence of events without assigning a definite age. Absolute dating refers to the process of examining a real fossil or the strata above and below it and giving an age to the fossil in reference to the present.

some plants can fling, squirt, or otherwise hurl their own seeds for some distance upon maturity. what is the maximum distance a seed is likely to travel using this mechanism?
Answers
Some plants can fling, squirt, or otherwise hurl their own seeds for some distance upon maturity. The maximum distance a seed is likely to travel using this mechanism is about 45 meters.
What is seed dispersal?Seed dispersal is the process by which seeds are distributed throughout a landscape. Seeds that are spread by plants are said to be dispersed, and they can be dispersed by a variety of methods, including wind, water, and animals. A seed's form can influence how it is dispersed.
The maximum distance a seed can travel using this mechanism is around 45 meters. Several plants fling their seeds, which are commonly referred to as ballistic dispersal mechanisms. The plants that fling their seeds include violets, touch-me-nots, and witch hazels, among others.
When the seeds are mature, the seedpod splits open, and the seeds are flung out. In the case of touch-me-nots, the slightest touch may cause the seeds to fly out from the seedpod. Seeds may travel significant distances if they are dispersed in this manner.

Briefly explain how the collateral ligaments and the cruciate ligaments of the knee stabilize the knee by preventing specific movements between the tibia and femur
Answers
The collateral ligaments and the cruciate ligaments of the knee stabilize the knee by crossing each other to form an X and joining to bones like the femur, patella, and tibia to provide preventing specific movements like side movements.
The two medial and sidelong collateral tendons work together to permit your knee to move accurately, whereas the front and back cruciate tendons limit it from moving within the off-base heading.
The quadriceps muscles work together with your hamstrings and tendons to stabilize your knees and permit them to work the way they are gathered to.
The lateral collateral tendon (LCL) is on the external side of your knee. It interfaces your femur to your calf bone (fibula). The collateral tendons anticipate the knee from moving side to side as well.
Cruciate tendons are the interior of your knee joint and interface your femur to your tibia. They cross each other to form an X.
The cruciate is the foremost vital knee tendon in giving soundness to the knee. There are two cruciate tendons, the front (ACL) and the back (PCL).
They sit profoundly interior of the center of the joint connecting to the tibia and femur. They cross over each other, thus their title, and take after the St Andrews Cross (X).

Show your work (calculations) 0.1 mL of an original sample is diluted into 9.9 mL of water, and then 0.1 mL of this is spread on a plate. 54 colonies grew. What was the original cell density of the sample?
Answers
The original cell density of the sample was 540 cells/mL. This was calculated based on the dilution factor and the number of colonies that grew on the plate.
To calculate the original cell density, we need to consider the dilution factor and the number of colonies that grew on the plate.
First, we determine the dilution factor. The original sample was diluted 1:100 (0.1 mL into 9.9 mL), resulting in a dilution factor of 1/100 or 0.01.
Next, we calculate the number of cells in the diluted sample. Since 0.1 mL of the diluted sample was spread on the plate and 54 colonies grew, we can assume that each colony represents one cell from the original sample.
Therefore, the number of cells in the diluted sample is 54 cells.
To find the original cell density, we divide the number of cells in the diluted sample by the dilution factor:
Original cell density = (Number of cells in diluted sample) / (Dilution factor)
= 54 cells / 0.01
= 540 cells/mL.
Thus, the original cell density of the sample is 540 cells/mL.

How do AM fungi affect D. lanuginosum plants grown at high temperatures?
1)- D. lanuginosum plants show increased shoot and root growth in pots inoculated with AM fungi.
2)- D. lanuginosum plants show similar shoot and root growth in pots with and without AM fungi.
3)- D. lanuginosum plants show decreased shoot and root growth in pots inoculated with AM fungi.
Answers
The correct answer is:
1) D. lanuginosum plants show increased shoot and root growth in pots inoculated with AM fungi.
Arbuscular mycorrhizal (AM) fungi have a mutualistic symbiotic relationship with plants, particularly in nutrient uptake. When D. lanuginosum plants are grown at high temperatures and inoculated with AM fungi, they show increased shoot and root growth. This positive effect can be attributed to several factors. AM fungi form a network of hyphae that extend beyond the root system, enhancing the plant's access to nutrients, especially phosphorus. They also improve the plant's tolerance to abiotic stresses, such as high temperatures, by enhancing water uptake and regulating plant hormone balance. Additionally, AM fungi can protect plants from soil-borne pathogens, benefiting their growth and health. The enhanced growth observed in D. lanuginosum plants inoculated with AM fungi is likely due to the improved nutrient acquisition and stress tolerance provided by the symbiotic relationship. This interaction highlights the importance of AM fungi in promoting plant growth and resilience, particularly under challenging environmental conditions.

b:Suppose instead that = 0.1, what then is ? (2 points)P(+)P(+|T+)
c:Why does change so much between a) and b)? (2 points)P(+|T+)
Answers
In part a, the probability of actually having COVID19 antibodies, P(+), is very low (i.e. 0.01). Thus, even with a high conditional probability of testing positive given that one has the antibodies (i.e. P(T+|+) = 0.96), the probability of testing positive overall (i.e. P(+|T+)) is still relatively low.
However, in part b, the probability of actually having COVID19 antibodies, P(+), is much higher (i.e. 0.1). This means that even though the conditional probability of testing positive given that one has the antibodies (i.e. P(T+|+) = 0.96) is the same as before
the probability of testing positive overall (i.e. P(+|T+)) is much higher because there are more people who actually have the antibodies. Therefore, the change in P(+|T+) between a) and b) is due to the change in the prior probability P(+), which affects the denominator of the formula for P(+|T+).
