Answer: Answer below
Explanation: pH is a measure of the acidity or alkalinity of a solution. What the pH scale measures is basically the concentration of hydrogen and hydroxyl atoms in a solution. So, the last option is the answer. Another thing to keep in mind is solutions with a pH under 7 are acidic, solutions with a pH of 7 are neutral, and solutions with a pH over 7 are alkaline or considered a base. I hope this helped! Good luck:)
Answer:
Pleiotropy
Explanation:
Marfan syndrome has several signs and symptoms depending on the individual affected.
The main manifestations of the disease are related to the skeletal system, in which the affected individual presents with elongated limbs, elevated height, scoliosis and thoracic deformations; the cardiac system, characterized by mitral valve prolapse (closing of the upper and lower chambers of the left side of the heart) and dilation of the aorta; and the ocular system, characterized by a detachment in the lens of the eye, and myopia.
The ability of genetic defects such as Marfan syndrome to reach such distinct organs is called pleiotropy.
Size, density, and growth rate are the three main ones. There is also dispersion, age structure, and survivorship. Hope this helps!
A complex assemblage of animals, plants, and their environment through which materials and energy move is known as ecosystem.
<h3>What is a ecosystem?</h3>
All the organisms that live in an ecosystem are present, along with their physical surroundings. Through energy flows and nutrient cycles, these biotic and abiotic components are interconnected. Plant tissue absorbs energy from the system through photosynthesis. Animals contribute significantly to the flow of matter and energy through the system by eating plants and one another as well as.
Additionally, they affect the biomass levels of the microbial and plant communities. Decomposers help to promote nutrient cycling by transforming nutrients stored in dead biomass back into a form that can be easily utilized by plants and microbes. They do this by consuming dead organic matter and releasing carbon back into the atmosphere.

Answer and Explanation:
<u>Cruza</u>: persona sana sin mutaciones con persona portadora
El parental sano aporta alelos normales del gen a la descendencia
El parental portador aporta un alelo normal y un alelo alterado. Tiene el 50% de probabilidad de transmitir la enfermedad a la progenie.
Parental) AA x Aa
Gametas) A A A a
Cuadro de Punnet) A A
A AA AA
a Aa Aa
F1) 2/4 = 1/2 = 50% de la progenie seran individuos sanos AA
2/4 = 1/2 = 50% de la progenie seran individuos portadores Aa
Como uno de los progenitores es portador, cada individuo tiene un 50% de posibilidades heredar el gen alterado.
