why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?
Answer: Meiosis must occur at some point in the life cycle to prevent a doubling of chromosomes in each generation.
Explanation:
Meiosis has to take place at some point in the life cycle in order to stop the chromosome count from doubling with each new generation.
What is meiosis?Meiosis is a specialised kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.
Meiosis results in the formation of four haploid daughter cells, each of which has the potential to differentiate into either sperm or egg cells in the future.

Directions: Choose 1 and write a constructed response as if you were in the situation and how you would work through the learned steps of stress management.
1- You’re hanging out with friends when someone joins the group and offers everyone a drink from a bottle in a bag. It smells strong. You pass the bottle on without taking any. Someone calls you chicken and the group pressures you to lighten up and have fun. What do you do or say?
2-Teams have been assigned for science class projects and you are having a hard time working with your partners. You shared an idea for a project, asking your team if they thought it would work. They called you names and said it was a lame idea. How can you deal with this situation to make it work?
3-Your best friend tells the person you like and think is cute that you have been talking stink about him or her. Another friend tells you to say something bad about your best friend to “pay them back.” You notice a stomachache and feel stressed about this. What do you do to fix this problem in the best way possible?
4-You tried out to perform in a local band but didn’t make it. The others thought you didn’t play the ukulele good enough and that you did not sing well. Your dream is to be part of a band, so you got mad and broke your ukulele. Now your mom is mad, too, as she got you the uke. How do you get over this and feel better?
5- You told your mom you wanted to go out with friends on Saturday night but she said you are still too young to drive in cars with other kids. Everyone else you hang with gets to go, but you don’t. Some says to lie to your mom and do it anyways. You really want to go out and don’t know what to do. What options do you have, and what would be the best choice?
6- Every day you have a really hard time staying awake in your classes. Teachers keep talking to you, but you don’t want to say you watch your baby sister till late while your mom works. It is hard for you to get much sleep because she is sick. You don’t want to fail or complain. What can you do to deal with the stress you are feeling?
I have chosen the first scenario.
In the way I would respond to people calling me chicken would be, “I do not want to be taken advantage of if I drink this, I don’t know what it is so I won’t drink it.” And if they continue I will just leave.
Which of the following should you NOT use to put out a chemical fire?
A.
Salt
B.
Water
C.
Sand
D.
Baking soda
Answer:
B. Water
Explanation:
A: Salt
Salt disperses heat and minimizes oxygen supply to a fire. This is especially useful if you experience a grease fire on or around the oven. Salt is also one of the main ingredients found in fire extinguishers.
Total Fire Group has a list of other things that can put out a fire
B: Water
Class B fires are made up of flammable liquids. If you were to throw water on a Class B fire, you might very well remove the heat and extinguish the fire but you would be equally likely to cause the flammable liquid to spray all over the place while it is on fire.
Firefighter Inside has an amazing article on the classes of fire, how to put them out, and why certain things (like water) can't be used to put out certain types of fires.
C: Sand
Sand suffocates the fire getting rid of the oxygen supply to the fire. and when the fire has no more oxygen it goes out.
Hunker has an article on how to put out a fire with a bucket of sand
D: Baking soda
Baking soda is good for putting out small fire cause the powder suffocates it and the bicarbonate in baking soda creates a chemical reaction when it gets hot enough that it starts to produce carbon dioxide, carbon dioxide removes oxygen from the fire causing the fire to go out.
Firefighter Now has a better and more detailed explanation on baking soda.

Answer:
Well considering there aren't really any clouds at night it would be easier to navigate and tell time at night now during the day clouds would be in the way of the sun at SOME times which is probably one out of many struggles our human kind had back then.
If the clouds were covering the sun whilst someone was trying to tell the time you'd just have to either wing it OR try your hardest to find the lightest parts of the clouds and assume the sun is in that position.

ldentify one health condition not mentioned in this activity that would warrant the use of a wearable device. What data might the wearable device record? What form of analysis might occur?
Answer:
Wearable technologies can be innovative solutions for healthcare problems. In this study, we conducted a literature review of wearable technology applications in healthcare. Some wearable technology applications are designed for prevention of diseases and maintenance of health, such as weight control and physical activity monitoring. Wearable devices are also used for patient management and disease management. The wearable applications can directly impact clinical decision making. Some believe that wearable technologies could improve the quality of patient care while reducing the cost of care, such as patient rehabilitation outside of hospitals. The big data generated by wearable devices is both a challenge and opportunity for researchers who can apply more artificial intelligence (AI) techniques on these data in the future. Most wearable technologies are still in their prototype stages. Issues such as user acceptance, security, ethics and big data concerns in wearable technology still need to be addressed to enhance the usability and functions of these devices for practical use.
