The chronological order of the response brought about by the nervous system is as follows.
1. Sensory receptors in the arteries detect low oxygen levels.
2. Sensory neurons generate an impulse.
3. The central nervous system relays an impulse to certain brain regions.
4. The brain sends signals through motor neurons.
5. Isabel's breathing rate increases.
The response to a stimulus is called a reflex action and the pathway traveled by the reflex action is called the reflex arch. A reflex action is an automatic involuntary response to a stimulus which minimizes any damage to the body. During conditions of low levels of oxygen in the body, the receptors detect the stimulus of low oxygen levels which could pose a threat to the individual and sensory neurons generate an impulse. It reaches the central nervous system and then the brain. In turn, brain sends signals through the motor neurons that carry a message and help in increasing the breathing rate of Isabel.
Answer: Venus, Mercury and Mars are the differentiated planets.
Planetary differentiation can be defined as the process by which the separation of different types of constituents takes place. They are differentiated on the basis of their chemical or physical behavior.The denser material of the planets sink to the center of the planet and the less denser particles rise at the surface of the planet.
One question is this supposed to be multiple choice?
This probably wont be the MOST accurate but this is the knowledge of a 6th grader (i tried)
Plants get their food from photosynthesising, they get their energy ffrom the sun and the chlorophyll is what capturers the suns energy. And once the suns energy has been caught then the electrons move around almost like they are excited to get the energy from the sun (the way some people get excited after consuming sugar a.k.a getting hyper) And the electrons are "jumping" in the thylakoid membrane. now there is enough energy to drive to the 2nd phase.
ADP becomes ATP that is when it is gaining more phosphate. Then the NADP gets more hydrogen to be able to store the energy now it has the hydrogen so it becomes.....NADPH. That is also kind of phase 3 the Calvin Cycle where G3P goes on to make glucose.
An animal gets energy from consuming the plants or other animals and sometimes even eating their own kind. Animals like deer, rabbits, moneys, pandas they all eat plants and or fruits. Because they get their energy from the plants and as said before that the plants get it from the sun. So basically all kinds of animals depend on the plants but some ocean creature dont really depend on plants but in some ways they do. Because not only for food, but for oxygen.
As you may have noticed i kinda know more about plants but soon i will be learning about animals since we are still learning about eukaryotic organisnisms.
Hope this helps. And have a great day! :)
Answer:
Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.
Explanation:
During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.
During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.
Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.
I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.
