Answer:
Abuelo/a con polidactilia heterocigoto, PpAbuelo/a normal, ppJuan normal, ppEsposa de Juan con polidactilia, PP o PpSantiago con polidactilia, PpExplanation:
Datos disponibles:
Polidactilia es causada por un alelo dominante, P.El alelo recesivo p produce numero normal de dedos.Francisco y Martha → Abuelos → uno de ellos con polidactiliaJuan → Hijo → Normal, ppSantiago → Nieto → PolidactílicoUno de los padres, ya sea Francisco o Martha, es polidactílico, lo que implica que ésta persona tiene, por lo menos, un allelo dominante en su genotipo, P- (El simbolo "-" esta representando un alelo dominante o uno recesivo).
Si Juan es normal, entonces su genotipo es pp, lo que significa que recibió un alelo recesivo de su padre y otro de su madre. Es decir que el parental policactílico es heterocigota, de forma que pudo heredarle un alelo recesivo a Juan. El otro parental probablemente sea normal, pp, pudiendo solo heredarle a Juan el alelo recesivo.
Entonces, uno de los padres tiene genotipo Pp (heterocigota) y el otro pp (homocigota recesivo).
Juan es norma, pp.
Santiago, hijo de Juan, es polidactílico, lo que implica que lleva en su genotipo por lo menos un alelo dominante, P. Pero Juan solo pudo heredarle un alelo recesivo, p. Por lo tanto, Santiago es heterocigota para la característica, Pp, y heredó el alelo dominante de su madre, que puede ser homcigota dominante PP o heterocigota Pp.
Supongamos que Francisco es polidactílico y Martha normal.
1º Cruza: Francisco x Martha
Parentales) Pp x pp
Gametas) P p p p
F1) 1/2 = 50% Pp
1/2 = 50% pp → Juan
2º Cruza: Juan x Esposa (opción uno: esposa homocigota dominante)
Parentales) pp x PP
Gametas) p p P P
F2) 4/4 = 100% Pp → Santiago
2º Cruza: Juan x Esposa (opción dos: esposa heterocigota)
Parentales) pp x Pp
Gametas) p p P p
F2) 1/2 = 50% Pp → Santiago
1/2 = 50% pp

como se coordinan el sistema nervioso y endocrino
Answer:
Las funciones de las glándulas endocrinas están estrechamente integradas entre sí y también existen conexiones anatómicas y funcionales entre el sistema endocrino y el sistema nervioso central y periférico: esto ocurre tanto a través de la médula de las glándulas suprarrenales, que secretan hormonas adrenalina.
Archaea (or extremophiles) like to live in extreme environments.
A. True
B. False
Answer:
A. True
Explanation:
We could just split the two parts of "extremophile'' and we get the gist.
"extremo-" (from Latin extremus) means to the highest degree of something.
"-phile" (from Greek philia), means love.
As a result, the term means "loving being in the highest degree (or something like that)."
To explain things, archaea are adapted to these extreme environments (hence the name extremophiles), except for hyperthermophily. Fungi, for example, live in mining areas, which are acidic and metal enriched.

Another term for the light-independent reactions of photosynthesis.
A. The Calvin Cycle
B. Cellular respiration
C. The nitrogen cycle
Answer:
A. The Calvin Cycle
Explanation:
The light-independent reactions cover half of photosynthesis, with the other half being the light-dependent reactions. Another word for this process is the Calvin cycle. It is named after the biologist, Melvin C. Calvin, who discovered it. The Calvin cycle is responsible for turning carbon dioxide into glucose. It also requires no light, hence its other name. Additionally, because it is occasionally called the Calvin cycle, sometimes, the light-dependent reaction is simply called the light cycle.
Answer:
A. The Calvin Cycle
Explanation:
The Calvin Cycle is the another term for the light-independent reactions of photosynthesis. So, option (A) is the correct answer.

Explanation:
What are valence electrons?
A. the atomic mass
B. the atomic number
C. all of the electrons in an atom
D. electrons in the outermost energy level
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
Answer:
D. electrons in the outermost energy level
Explanation:
The valence electrons are the electrons in the outermost energy level.

Electric current is the flow of ________ through a substance.
Answer:
Electrons
Explanation:
Answer:
A current is a flow of electrons for this to happen there must be a closed circuit.
- The electricity is nothing but a flow of free electrons present in the external surface of the electricity conducting substance.
The flow direction of this electron flow is also the direction of electricity flow.
- There is a type of electrical circuit which is known as the closed circuit. This circuit is completely connected with the two terminals of the battery and there are no hindrances in the path of electricity flow in these circuits. That's why current can only flow through these complete circuits.
What happens during the process of translation?
Explanation:
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins.

The overall process of photosynthesis can be written as the equation:
A. 6 glucose + 6 water --> 6 oxygen + 6 carbon dioxide + light
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
C. 6 oxygen + 6 water (+ light) --> 6 glucose + carbon dioxide
Answer:
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
Explanation:
Remember that in a chemical equation the reactants (input) are on the left and the products (output) are on the right. For photosynthesis to occur 3 different reactants are needed: water, carbon dioxide, and light. Note that because the light is not an element or molecule, it is sometimes written in paratheses or left out of the equation. Then, the products are glucose, which is the intended product, and oxygen, which is an unintentional byproduct that is released back to the atmosphere. Additionally, the equation for cellular respiration is the opposite of this, with the products as reactants and vice versa (except ATP is switched in for light).

What was Darwin’s conclusion about the shells in Santiago
Answer:
Darwin noticed that the plants and animals on the different islands also differed. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells (see Figure below). People who lived on the islands could even tell the island a turtle came from by its shell.
