Energía.
Explicación:
Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.
Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.
En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.
Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.
Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.
Answer:
Energy.
Explanation:
Generally, electrons revolves continuously in the shells of atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.
They are needed for chemical reactions of a particular atom with another,through their loses or sharing.
In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.
However, if certain quantity of energy is supplied to such atom, the electron gains energy and therefore becomes excited.
They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

Answer:
to. 1. Cell-mediated immunity Cytotoxic T lymphocytes attack and destroy foreign cells and viruses Antibody-mediated immunity
b.1. Cell-mediated immunity T cells mature in the thymus before they circulate. Immune.
C. 1. Cell-mediated immunity B cells differentiate into plasma cells.
re. 2. Antibody-mediated immunity Antibodies adhere to specific targets.
me. 1. Cell-mediated immunity B cells mature in the red bone marrow before they circulate the antigen.
f.1. Cell-mediated immunity Memory T cells are subsequently activated by the same 6 antigens.
g.3. Immune surveillance NK cells monitor peripheral tissues for cancer and abnormal cells.
Explanation:
Cellular immunity is mediated by the cells of the immune defense, it presents different times, in the first time the PMN appear, in the second time the antigen presenting cells, and lastly the lymphocyte lineage.
Antigen presenting cells have the ability to phagocytose and express antigen on their surface to facilitate the formation of antibodies.
Surveillance immunity refers to the lymphocytes that are responsible for monitoring or controlling cell mutations or uncontrolled growth due to genetic mutations.
Neoplastic cells express histocompatibility complexes on their surface that make them recognized by these lymphocytes and this is how they are responsible for inducing self-destruction or phagocytosis of the neoplastic cell.
Humoral immunity refers to the chemical substances that function as mediators of cell activity, these are: pro and anti-inflammatory cytokines, complement chain, nitric and nitrous acid, oxygen free radicals, interleukins, growth factors and tumor necrotic factor alpha - beta
Why hydrophytes do not have cuticle on stem or leaves? answer just in 4 to 5 lines
Explanation:
The cuticle is a layer of tissue on the outside of most leaves and stems, and its primary function is to help the plant conserve moisture. Since hydrophytes are full of water and moisture, it does not need a cuticle.Most aquatic plants don’t need to seal in moisture, so they don’t have cuticles
Do you think the processes that form and shape the small stream bed are similar to those that form and shape the Grand Canyon? Why or why not?
Answer:
Due to the flowing of stream and river.
Explanation:
The processes that formed the small stream bed are similar to those that formed the Grand Canyon because both are formed by the flowing of river. The river flow through these regions and with this flow they takes rock particles with itself and makes several shapes and structures of that region. So we say that rivers and streams are responsible for the formation of stream bed and Grand Canyon.

Use the picture to tell if it is accurate , precise , or both?
Answer:
Accurate - Yes
Precise - Yes
Explanation:
Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.
Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.
Note that, a measurement may be accurate but not precise or be precise but not accurate.
In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.
Therefore, the measurements are both precise and accurate.

Elabora un párrafo utilizando las siguientes palabras; sistema nervioso, sistemas, neuronas, sistema endocrino, glándulas, hormonas, sangre, mensajeros químicos
Answer and Explanation:
El sistema endocrino esta compuesto por tejidos y glándulas que se encuentran en distintas partes del cuerpo y que cumplen funciones de control sobre distintos órganos. Se encarga de la síntesis y secreción de hormonas en función de las necesidades del organismo. Las glándulas secretan hormonas a la sangre que actúan como mensajeros químico y que son transportadas hasta los tejidos destino, donde transmiten la señal adecuada de regulación celular. El hipotálamo y la hipófisis son dos glándulas que se ubican en la zona central-inferior y en la base del cerebro, respectivamente. El hipotálamo regula el funcionamiento de la hipófisis a través de secreción hormonal. Secreta hormonas en capilares que se dirigen hacia la hipófisis. La hipófisis, también conocida como glándula pituitaria, secreta hormonas que se dirigen a distintos tejidos del cuerpo. Tanto el hipotálamo como la hipófisis están regulados por el sistema nervioso, cuyas unidades funcionales y estructurales son las neuronas. Estas se encargan de enviar impulsos nerviosos en la comunicación inter-neuronal. Ambos sistemas mantienen estrechos sistemas de comunicación.

Which of the following is true about an acidic solution
A-Its pH is below 7
B-Its hydrogen icon concentration is low
C-It is neutral
D-It can act as a buffer
Hey There!!~
Which of the following describes why ice floats?
Your answer is B. The density of ice is lower than that of liquid water. Because, As the water cools, the particles slow down and the bonds last longer. These bonds cause the water molecules within ice to form a lattice-like structure that is less dense than liquid water. So, ice floats on the more dense liquid water.
Why is water vital to maintaining a constant internal environment?
Your answer is C. It is good solvent. It is the maintenance of a constant internal despite changes in internal and external conditions. In the human body, this includes control of: blood glucose concentration.
Your answer is A. Its pH is below 7. Because, An acidic solution is one in which the concentration of hydronium ions is greater than that of hydroxide ions. This makes the pH less than 7. An acidic solution is an electrolyte and conducts electricity.
Hope This Helps!!

Zygomycota produce
which germinate into new hyphae.
hyphae
asci
zoospores
zygospores
Zygospores
Zygomycota produce zygospores, which germinate into new hyphae.
Explanation;
The reproductive world of fungi ranges from bursting spores to fruiting bodies.
During asexual reproduction, some hyphae become spore-producing bodies called sporangia or conidia. The group of fungi known as Zygomycota develop sporangia within a sac. This sac then bursts to release the spores.
Once the spores land on a suitable habitat, they germinate a new hypha that grows into a mycelium.
Zygomycota, Ascomycota and Basidiomycota each reproduce sexually. The difference is the structure the spores form in. Basidiomycota form fruiting bodies called mushrooms or basidius; Ascomycota have sacs called ascus; and Zygomycota produce zygospore.
Answer:
the answer is Zygospores
