Your answer would be Event 1 shows lunar eclipse and Event 2 shows solar eclipse.
This is because of the positioning of all three of the objects.
The sun is the light source, and therefore things are only visible because of light reaching our eyes, from the sun, either reflected or direct.
In the case of Event 1, the earth is blocking the sunlight from reaching the moon, so therefore it would be a lunar eclipse, as the moon would not be visible.
In the case of Event 2, the moon is blocking sunlight from reaching parts of the earth, so therefore the sun would not be visible, and it would be a solar eclipse.
Hope this helped!
Answer:
Explanation:
The sperms are the male gametes these develop in the testicles which are the male reproductive organs. Each testes consists of system of tubes called as seminiferous tubules. In seminiferous tubules the spermatogenesis takes place in which the development sperm cells receives nourishment for maturation.
The sperms moves from the seminiferous tubules to the duct like vas deferens from where the sperm moves to be ejected out of the body. If the sperms were produced by the solid tissue except the seminiferous tubules the movement of sperms will be restricted the ejection process may get slow down.
Answer:
B and C
Explanation:
When the Amish came to their new home, they were founding a new colony. This is considered a founding effect.
Now, there is another thing to keep in mind, and that is that the Amish are very strict about their custom, for example, the idea of family and identity. This led them to form couples, only among the members who belonged to the community.
As generations go by, genealogical relationships between individuals in the population become closer. This causes some genes, by mere probability, to become fixed (i.e. they are the only ones left in the population). As a consequence of this, the frequency of rare genes increases (polydactyly). This evolutionary process is known as gene drift.
Hi there!
A prezygotic isolating mechanism is a mechanism that causes something to happen, not allowing the organisms to breed before fertilization. I'll explain each one for you.
A - That is postzygotic because the organisms were not stopped before fertilization. The result is a sterile organism.
B - Again, that is postzygotic because the organism was produced.
C - This is prezygotic! The sperm dying shows that something is in action to prevent fertilization, meaning that it cannot happen.
D - Fertilization was successful, so it is postzygotic.
ANSWER:
C - the sperm dies when it reaches the female tract

<u>Answer:</u>
Integrator compares sensory information to a target value.
<u>Explanation:</u>
- Integrator is responsible for sending 'instructions to an effector' based on 'sensory information' which eventually give responses.
- These effectors execute the necessary changes required to adjust with the environment. Integrator act as the control centers.
- Integrators send signals to the effectors after comparing the variables or changes at a definite set point.
- However, its function mechanism is 'dependent on the feedback loop'.
