El pelaje negro de los borregos se debe a un alelo recesivo n frente a su alelo N que determina el pelaje blanco. Si cruzamos un individuo homocigótico blanco con un homocigótico negro, ¿de qué color serán los descendientes de la primera generación filial? GENOTIPO-FENOTIPO
Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.
Explanation:
Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.
En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).
Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)
El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Would you predict more earthquakes in areas where tectonic plates are colliding or where they are moving apart?
PLSS HELPP MEEE
Answer:
Maybe where they are colliding because when they collide there is going to be a wave of impact that will go to the surface
Explanation:
Droughts occur due to climate change and elevated temperatures, which in turn may lead to other consequences as well. Imagine that a wildfire happened in the nature reserve. Predict what would happen if such an environmental shift that is so extreme and rapid
Hits the nature reserve and the population of deer mice does not have time to adapt. Propose a possible solution for this problem.
Answer:
this is not a correct Q
this is wrong
this part too #stresscrying
Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.
5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

two examples of heat energy
Answer:
sun and electric heater
Explanation:
sun is the biggest source of heat energy
electric heater is also an example of heat energy as it warms us
1. A cup of fresh coffee is very hot because the water particles are vibrating very rapidly giving the coffee heat energy.
2. A fire is a chemical reaction that is releasing energy as bonds are being broken, this energy is felt as warm or hot and is a release of heat energy.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
