If there is no fertilization, degeneration of the corpus luteum results in a drop in _____, which results in the sloughing off of the uterus's endometrium.
Degeneration of the corpus luteum results in a drop in progesterone production.
What is progesterone?Progesterone is a hormone produced by the corpus luteum that allows the uterus to prepare for fertilization. The halt in production of this hormone then causes the sloughing of the uterus's endometrium, which results in the individual undergoing the process of menstruation.
Therefore, we can confirm that the degeneration of the corpus luteum results in a drop in progesterone production.

Your body needs a constant supply of oxygen for cellular respiration to produce the ATP needed to fuel your body processes. When you exert yourself in a strenuous workout the oxygen demands of your muscle cells quickly outpace the oxygen your body can provide. Skeletal muscle cells that have an insufficient oxygen supply to allow aerobic respiration to continue will undergo lactic acid fermentation. Refer to the model above. Predict what changes will occur when your body shifts from aerobic respiration to anaerobic respiration (lactic acid fermentation). Select ALL that apply.

Explanation:
The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.

Scientists have noted a difference in the concentration of atmospheric gases available to Norway spruce trees at site 1 and site 2. Use Table 1 and Figure 2 to describe the difference in atmospheric gases at each site. Explain how the flow of matter and energy differs in these two locations as a result of the concentration difference. Use evidence from any of the tables or figures to support your answer
The concentration of gases in the atmosphere available to the Spruce trees depends in the number of trees in each location.
How do the amount of trees in an area affect concentration of atmospheric gases?The atmosphere contains a mixture of gases such as carbon dioxide, water vapor, oxygen and nitrogen.
Plant such as trees are known to contribute to the amount of gases present in the atmosphere.
Trees remove carbon dioxide from the atmosphere and release oxygen into the atmosphere.
Therefore, the concentration of gases available tongue Spruce trees depends in the number of trees in each location.

The fibrocartilage pad between the medial condyle of the femur and the medial condyle of the tibia is called the __________.
Medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.
What is medial meniscus?It is an articular fibrocartilage that extends medially across the knee joint, where it attaches to the tibia anterior to the insertion of the anterior cruciate ligament.
This in the middle zone has continuity with the deep portion of the medial ligament, being well attached to the tibia and femur and acting as a cushion and distributing the weight of the femur.
Therefore, we can conclude that the medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.

Which of the following is most affected by natural selection?
Angora rabbits

Influenza (The Flu)
Poodles
Answer:
Influenza (The Flu)
Explanation:
Influenza (the flu virus) is a real-life example of natural selection that is most evident during an annual time period when the influenza virus infection peaks. The repeated or cyclical nature of flu outbreaks is caused by the natural selection of the virus for traits that allow it to evade the immune system and replicate, a process that actually results in new distinct strains of influenza virus.

Tmp/smx has two components that act on different steps in the folic acid biosynthesis pathway and are thus used together. sulfamethoxazole is a structural analog of a compound called paba, competing with it in the enzymatic production of dihydrofolic acid, an intermediate in the synthesis of folic acid. trimethoprim inhibits the step following dihydrofolic acid production and prevents the formation of the biologically active form of folic acid. choose true statements regarding tmp and smx.
Trimethoprim-sulfamethoxazole (TMP-SMX) are a class of antibiotics used in the treatment of bacterial infections due to their inhibitory actions in the folic acid biosynthesis pathway of bacteria.
What is TMP-SMX?Trimethoprim-sulfamethoxazole (TMP-SMX), otherwise known as co-trimoxazole, is a combination of two antimicrobial agents that work synergistically to inhibit the enzyme systems involved in the bacterial synthesis of tetrahydrofolic acid.
They are used in the treatment of urinary tract infections, respiratory tract infections, cholera, etc.
