Aerobic respiration involves the reaction of oxidation which involves the acceptance of electrons when the molecular oxygen reacts with protons to form water molecules. Thus, the correct option is A.

What is Aerobic respiration?

Aerobic respiration is the chemical process in which molecular oxygen is used to make the energy in the form of ATP from carbohydrates. It is also called as aerobic metabolism, and oxidative metabolism.

Aerobic organisms can use molecular oxygen (O₂) to generate energy in the form of adenine triphosphate (ATP). The role of molecular oxygen in the process of cellular respiration is to act as the end acceptor of electron. As the electrons are dropped off at the inner mitochondrial membrane during the process of cellular respiration, they travel through the electron transport chain and  are finally accepted by the molecular oxygen to form water.

Therefore, the correct option is A.

Célula: Unidad básica de todos los organismos

Tejido: Conjunto de células especializadas que tienen una forma similar y una actividad determinada

Órgano: Estructura formada por diferentes tipos de tejidos, que coordinan sus funciones para realizar una tarea especifica

Sistema: Conjunto de órganos que trabajan de forma integrada y cumplen una función especifica en el organismo.

Organismo: Nivel de mayor complejidad. Constituido por sistemas, que realizan sus funciones en forma coordinada

Explanation:

Los organismos pueden ser unicelulares o pluricelulares. Estos últimos tiene muchas células, lo que hace que tengan estructuras mucho más complejas. En ellos hay distintos niveles de organización celular. Se le llama así porque es la célula la unidad básica de absolutamente todos los organismos. En el segundo nivel encontramos los tejidos, en el tercer lugar los órganos, luego en el cuarto nivel los sistemas y por último todos ellos constituyen un organismo, que es el quinto nivel de organización celular.

A su vez, cada uno de estos elementos mencionados en los distintos niveles de organización celular tienen sus propias características y funciones que hacen que se puedan clasificar y dividir en distintos tipos.

B. The native snail species will move to another area allowing the ecosystem to remain stable.

C. The native snail species will share their food with the invasive species stabilizing the ecosystem.

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Answers

Answer:

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Explanation:

In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.

In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.

Which of these characteristics is NOT a property of water? (SC.912.L.18.12) A. Increases density as it solidifies B. Functions as a universal solvent C. Exhibits a highly cohesive behavior D. Moderates changes in temperature

Answers

Answer:

Option A.

Increases density as it solidifies

Explanation:

Increases density as it solidifies is not the characteristics of water because when water solidifies or freeze it become less dense or lighter compare to liquid water. When water solidifies to ice, it molecules are packed together and it is arranged in six sided crystalline shape which make it to be less dense or lighter than the liquid water molecules which is denser or more heavier.

There are only three autosomal trisomic conditions (Patau, Edward, and Down Syndrome) where a fetus will survive to birth. Why do you think this is so?

Answers

Answer:

An autosomal trisomic condition is the deviation of the chromosome number where an extra copy of the chromosome present with the chromosome pair. The three trisomic conditions are Patau - extra copy at chromosome 13, Edward - extra copy of chromosome 18, and Down Syndrome - an extra copy of chromosome 21

Children or fetuses affected by these trisomies show the least life expectancy and develop as mentally week, other than these trisomies other trisomic conditions are highly lethal so we do not see the survivors and it is due to dosage sensitivity which means that increasing or decreasing their expression levels will reduce cell viability.

Why does ice become less dense than water?

Answers

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

What composes a photosystem?

Answers

The "special chlorophyll" molecules in the reaction center are what the photosystem will use to absorb all of the sun's energy.

What is a photosystem?

A core complex and a periphery antenna system referred to as the light-harvesting complex I (LHCI) for PSI and the light-harvesting complex II (LHCII) for PSII, respectively, make up each photosystem.

Light-harvesting structures and reaction hubs make up photosystems. To two unique chlorophyll molecules in the reaction center, pigments in the light-harvesting complex transfer light energy.

Sunlight is captured in the chloroplast by pigment chlorophyll molecules arranged into photosystems.

Therefore, the light-harvesting complex, which consists of pigments, and the reaction center make up the photosystem.
