Answer:
The correct answer is: a. True.
Explanation:
There are several membrane transport systems responsible for the passage of ions like Na+ and K+.
Cell membranes are semipermeable, which means they can regulate which molecules may and cannot flow through them. Some molecules may simply drift in and out of a cell (this is called simple diffusion), while others require specific structures to enter and exit (this type of diffusion is called facilitated diffusion), and still, others require an energy boost to pass the cell membrane (this is known as active transport).
Both simple diffusion and facilitated diffusion are types of passive transport: they happen without the energy boost that ATP gives, unlike active transport.
In passive transport, molecules follow their chemical gradients and travel through the most concentrated compartment to the less concentrated one to equal the concentrations. In active transport, on the other hand, the cell makes an effort to enter or exit ions against their chemical gradients and this is done particularly to maintain said gradients (they are required for the correct functioning of the cell).
Sodium and Potassium are two of the most important ions when it comes to maintaining these gradients: sodium is very concentrated in the outside of the cells (the extracellular compartment), while potassium is highly concentrated in the intracellular compartment. These differences in concentrations are maintained thanks to the Na+/K+ pump, a form of active transport. Apart from the Na+/K+ pump, these ions go through the membrane through passive transport as well, without requiring energy.

Which of the following is NOT a function of behavior?
A. To produce ATP.
B. To find food.
C. To reproduce.
D. To avoid predators.
Answer:
A to produce ATP as you are subconsciously producing ATP and you can not control it
Explanation:
To find food, to reproduce, and to avoid predators all are the functions of behavior except the production of ATP. Thus, the correct option is A.
What are the functions of behavior?Behavior is the range of actions and manners which are made by individuals, systems or artificial entities in a given environment. This can include other systems or organisms as well as inanimate physical environment.
The four main functions of behavior of an organism are attention, escape, access, and sensory needs. These four functions allow us to understand and categorize someone's actions, as well as determine the behavior of organisms such as finding food, reproduction, and avoiding the predators.
Therefore, the correct option is A.

La actividad de agua (aw) es la cantidad de agua libre en el alimento, es decir, el agua disponible para el crecimiento de microorganismos y para que se puedan llevar a cabo diferentes reacciones químicas. Tiene un valor máximo de 1 y un valor mínimo de 0. Cuanto menor sea este valor, mejor se conservará el producto. La actividad de agua está relacionada con la textura de los alimentos: a una mayor actividad, la textura es mucho más jugosa y tierna; sin embargo, el producto se altera de forma más fácil y se debe tener más cuidado.A medida que la actividad de agua disminuye, la textura se endurece y el producto se seca más rápido. Por el contrario, los alimentos cuya actividad de agua es baja por naturaleza son más crujientes y se rompen con facilidad. En este caso, si la actividad de agua aumenta, se reblandecen y dan lugar a productos poco atractivos. En ambos casos, el parámetro de la actividad de agua del alimento es un factor determinante para la seguridad del mismo y permite determinar su capacidad de conservación junto con la capacidad de propagación de los microorganismos.Agua y microorganismosControlar la actividad de agua en alimentos es sinónimo de alargar su vida útilCuanto menor es la actividad de agua de un alimento, mayor es su vida útil. Es importante diferenciar entre cantidad de agua y actividad de agua. El primer término hace referencia a la cantidad total de agua presente en el alimento, aunque puede ser que no esté libre para interaccionar. La actividad de agua, en cambio, hace referencia solo a la cantidad de agua libre en el alimento y disponible para reaccionar, es decir, la que puede facilitar la contaminación del producto.Los

Which of the following statements best represents the theory of pangenesis developed by Hippocrates?
a. Pregnancy is a spontaneous event, and the characteristics of the offspring are determined by the gods.
b. Particles called pangenes, which originate in each part of an organism's body, collect in the sperm or eggs and are passed on to the next generation.
c. Offspring inherit the traits of either the mother or the father, but not both.
d. Fertilization of plants is dependent on an animal.
e. Heritable traits are influenced by the environment and the behaviors of the parents.
Answer:
b. Particles called pangenes, which originate in each part of an organism's body, collect in the sperm or eggs and are passed on to the next generation.
Explanation:
Particles called pangenes, which originate in each part of an organism's body, collect in the sperm or eggs and are passed on to the next generation. The belief of Hippocrates states that "the semen was derived from the whole body." which means the whole body contributes the formation and creation of semen that is responsible for the fertilizing the female's egg with its sperm.
Name one geographic region that has few or no fossil primates and explain why.
Answer:
Australia
Explanation:
Fossils are preserved remains (or mouldings) of ancient living things which are preserved in sedimentary rocks. Primate fossils are generally found along with other fossils, usually in ancient soils that contain information on the conditions under which they were formed. Primate fossils are generally found in tropical and subtropical regions (which represent the natural habitat in which these species live). Primates never lived in Australia, and therefore no fossil primates from this geographic area have been found.

Mycelium
Septum
Hyphae
Answer:
Ascomycetes have zygotes
Mycelium

Ascomycetes have zygotes which is the main distinction between Ascomycetes and Basidiomycetes. Mycelium is a part of mushroom that is edible and can be eaten. Mycelium is the vegetative part of a fungus that consist of a mass of branching, thread-like hyphae. Hypha is a long, branching, filamentous body of mushroom as well as oomycete and actinobacteria. Hyphae are the primary mode of vegetative growth of fungi which is generally known as mycelium so mycelium is the edible part of mushroom.
