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.
Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.
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.

Cuanto más fría es la temperatura en un lago, más oxígeno retiene el agua. Daniel se da cuenta de que pesca más peces en un lago que está a menos de 55 grados. Quiere realizar un estudio para capturar la mayor cantidad de peces posible este año. Necesita un poco de ayuda para escribir una pregunta comprobable y una hipótesis. Por favor ayudarlo.
Answer:
- Pregunta ¿la temperatura incide en la cantidad de oxígeno disuelto en el agua del lago?
- Hipótesis: temperaturas más frías están directamente asociadas con un incremento en la cantidad de oxígeno disuelto en el agua del lago
Explanation:
Para poder aplicar el método científico, lo primero que debemos hacer es formular una pregunta sobre algún fenómeno observado en el mundo natural. A continuación debemos formular una explicación posible o 'hipótesis' que permita responder la pregunta que formulamos anteriormente. A partir de la hipótesis podemos diseñar experimentos y/o observaciones empíricas que permitan probar la veracidad de nuestra hipótesis de trabajo. En este caso, por ejemplo, el experimento podría consistir en la medición y posterior comparación del nivel de oxígeno disuelto en el agua del lago durante la temporada de altas temperaturas versus la temporada de bajas temperaturas. Finalmente, los resultados observacionales/experimentales nos permitirán comprobar o rechazar la hipótesis de trabajo (en este caso, nuestra hipótesis es que el nivel de oxígeno disuelto es mayor a bajas temperaturas), obteniendo de este modo una conclusión a partir de nuestro trabajo.

Explain how building the lake near Galetown could affect the amount of water vapor and the amount of rain.
Answer:
Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

As native mason bees visit flowers, they spread pollen while also consuming nectar from the plant. This is an example of symbiosis.
true or fasle
Answer:
True
Explanation:
Symbiosis is a type of relationship or interaction between two different biological organisms/species by which both are benefited. The bees such as mason bees are pollinators. Pollinators are animals (especially insects) that help the development of seeds and the fruit surrounding seeds by the pollination of flowers, i.e., by the transference of pollen from male anthers of a flower to the female stigma. During this process, pollinators eat nectar, which is a sweet energy-rich liquid secreted by flowers. In consequence, both species (i.e., plants and mason bees) are benefited from this interaction.
what law out of newtons law is this statement ? please help
( The phone will hit the ground and the ground will push up with the same force. With a case, it is increasing the amount of time the phone hits the ground. This means the reaction force will be less.)
Answer:
Newton's Third Law
Explanation:
Newton's Third Law is: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
In this case, Object A is the Phone, and Object B is the ground. When the phone(Object A) hits the ground(Object B), the ground pushes up on the phone making the time increase and makes the reaction force less. Hope this helps!

2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the medulla oblongata). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the corpus callosum.
Describe how organ systems interact to get oxygen to the cells
The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.
What is oxygen in the body?Our bodies require a specific amount of oxygen to function effectively since oxygen is necessary for life. When you breathe (inhale), oxygen enters your body through your mouth or nose and travels through your lungs into your bloodstream.
Oxygen inhaled by the lungs is also carried by your blood. Your body's other cells receive oxygen and nutrition from your circulatory system, which then collects any waste products they produce, including carbon dioxide, and transports them to your kidneys and lungs for elimination.
Therefore, the blood collects food nutrients from the small intestine and transports them to every cell in the body.
