Answer:
The burning and cutting of the trees will affect the carbon cycle by adding carbon dioxide to the atmosphere, in the case of burning the trees and by not removing enough carbon dioxide from the atmosphere in the case of cuting the trees.
Explanation:
When burning and cutting down trees, these actions significantly alter the carbon cycle, adding carbon dioxide in the case of burning trees and preventing said carbon dioxide from being eliminated when cutting down the trees that, through the process of photosynthesis, are responsible for cleaning the atmosphere transforming carbon dioxide into oxygen.
Where these processes lead to carbon cycle stagnation in the short and long term.
The giant african land snail is an invasive species that is also the largest snail ons earth what is most likely consequence of introducing this invasive species into a stable ecosystem?
A. The native snail species will change their diet therefore destabilizing the ecosystem.
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
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.

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?
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.
What best describes the role of molecular oxygen (O2) in aerobic respiration?
A. It accepts electrons when reacting to form water.
B. It combines with carbon and hydrogen to form glucose.
C. It is released when glucose breaks apart.
D. It reacts to form carbon dioxide and water.
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.

Answer:
A compound is chemically bonded whereas mixtures are not. Compounds have a set amount of atoms that are conjoined, maybe through the process of heat, acid, water, etc, but, mixtures two things roughly mixed together, not chemically bonded.

What composes a photosystem?
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.

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
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.

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.
