Answer:
Follicular phase
Explanation:
Menstrual cycle consists of 3 phases namely:
1. Follicular phase.
2. Ovulatory phase
3. Luteal phase
The follicular phase is stimulated by the follicle stimulating hormone(FSH). The first day of menstrual cycle marks the beginning of the follicular phase. The estrogen and progesterone reduces together with shedding of the uterine lining. In this phase and the follicles starts to form in the ovary. As time goes on only one follicle which contains egss continues to develop in the ovary which is released later.
Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
Answer:
This can be explained based on structure, and on metabolisms of carbohydrate.
Explanation:
Carbohydrate has a relatively simple structural composition than the either protein or fatty acids. The C, H and Oxygen molecules are of relatively fewer in number and few chains than fats and protein.Thus cells will spend less energy to break bonds(catabolisims) among these molecules during cellular respiration pathways to trap the energy.
In addition glucose the end products of carbohydrate did not need any processing before it enters glycolysis, Kreb's Cycle and oxidative phosphorylation pathways to generate energy for the cells.
Conversely, for protein to be used it has to be first deaminated(removal of amino acid) by the liver before it enters glycolysis,while fats needs to be broken down and undergo beta oxidation with the long chains removed before it can form acetyl CoA. Therefore cells will prefer few steps, less endergonic pathways of glucose than longer more endergonic amino acids and fatty acid pathways.
Furthermore, glucose can be used in cellular respiration to produce energy either aerobically or anaerobically, while fats can only be used anaerobically. Therefore, since cells usually prefer to thrive in aerobic conditions they breakdown glucose easily during this period, and when lack of oxygen occurs they switched to anaerobic, Thus, the versatility of glucose to oxygen concentration makes glucose a better choice. Besides if fats was used anaerobically, ketone bodies build up which may be toxic to the cells.
Answer:
C.
Explanation:
Because it's giving a brief description of how it looks and what it's function is, which as listed a seismograph is used to record ground motion such as caused by earthquakes, volcanic eruptions and explosions.
