Answer: Xiao can use these structures to create a similarity matrix that enables to differentiate between synapomorphies and homoplasies .
Explanation: A synapomorphy is a trait that has been inherited from the same ancestor, this trait enables to establish a relation of homology between two or more species; while a homoplasy is an analog structure that doesn't have homology.
Answer:
The label A corresponds to Convergent boundary zones
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped <u>volcanic islands</u>, t<u>he island arches</u>. Subduction zones coincide with deep-sea <u>trenches</u> or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.
Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
The correct answer is: It enters the citric acid cycle and associates with a 4-carbon molecule (OXALOACETATE), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
The citric acid cycle is a cyclic process (part of the cellular respiration) where acetyl CoA is modified in the mitochondria to produce high-energy intermediate molecules for the oxidative phosphorilation (production of ATP).
Answer:
1. Insulin resistance and diabetes
2. Metformin
Explanation:
Metformin can be used to treat polycystic ovary syndrome, especially for insulin-resistant women (insulin is a hormone that transports sugar into cells).
People with insulin resistance have high levels of this hormone in their blood and excess circulating insulin can aggravate manifestations of polycystic ovary syndrome, and also increase the risk of diabetes.
The main benefits of metformin in the treatment of polycystic ovaries is the normalization of menstrual irregularity and the restoration of ovulatory cycles.
Since most women with polycystic ovary syndrome are insulin resistant, metformin is a good treatment option in some cases.
However, the treatment of polycystic ovary syndrome should be individualized for each woman, depending on the symptoms presented and the goal to be achieved with the treatment.
