The eye spot and the chloroplasts work together to help the euglena survive because the eye spot senses the light and the dark. Since euglena need to do photosynthesis in which uses light energy to make usable energy, to get food, the eye spot will tell the euglena where to move in order for it to be able to do photosynthesis.
<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.
<u>Explanation:</u>
To calculate the weight of a person, we use the formula:
....(1)
where,
w = weight of an object
m = mass of the person = 65kg
g = acceleration due to the gravity of the planet
For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:
where, g = acceleration due to gravity = 
G = Universal gravitational constant = 
M = mass of the planet = 
r = distance of the person from the planet = 
Putting values in above equation, we get:
Putting this value in equation 1, we get:
Hence, the weight of the person above the surface of a planet is 635.83N.
Answers:
el pelo rizado en los perros domina sobre el pelo liso. una pareja de pelo rizado tuvo un cachorro de pelo tambien rizado y del que se quiere saber si es heterocigótico ¿ con que tipo de hembras tendrá que cruzarse?
4.6/5

El cachorro puede ser "Aa" o "AA". Se quiere saber si es "Aa". Para eso, tendría que cruzarse o con un homocigoto recesivo (aa), puesto que es el que da un 50% de probabilidades de que los hijos sean de pelo rizado.
Entonces, si se cruza con un homocigoto recesivo, la probabilidad de la descendencia debería ser 2 cachorros de pelo rizado y 2 cachorros de pelo liso.
La hembra tendría que ser de pelo liso para asegurarse de que sea homocigoto recesivo.
Si todos los cachorros salen con el pelo rizado, entonces el padre es homocigoto "AA".
Si al menos uno sale con el pelo liso, entonces el padre es heterocigoto "Aa"
<span>This is an example of a moral dilemma. A moral dilemma is a situation where you are asked to choose between two different situations in which moral reasoning is required in your decision making. Here, the moral reasoning comes down to killing animals for the benefit of human life.</span>
Answer:
The correct answer will be:
1. Mutualism
2. Competition
3. Commensalism
Explanation:
In an ecosystem the organism interacts with each other in one of the following ways:
1. <u>Competition</u>- interaction occurs when two or more than two species depend on the same resources, sharing the same habitat and niche. These species will fight for the resources and both will be negatively affected.
2. <u>Commensalism-</u> interaction takes place when one organism is benefited while the other is neither harmed nor gained. For example- the interaction between Remora fish and large fish in the ocean.
3. <u>Mutualism</u> -occurs when the species are dependent on each other for the resources and both benefits each other. For example- the plants and birds co-evolved benefiting each other like animals helps in pollination and plants provide nectar to them.
Thus, the selected options are the correct answer.
