Question 1

do we have the same genes as our ancestors

Accepted Answer

mostly. You see all humans on earth have a 99.9% identical genitic makeup.The remaning .1% sperates you from the world. Usually your genetics are similar to your ancestors but not fully. Over time genes change and can mutate. If you can find some photos of your recent ancestors look at their face shape jawline bodybuild. Most likely it is similar to yours. In the end yes you do have the same genes as your ancestors, but only to an extent.

Question 2

bruhhhh science is sooo hard

Accepted Answer

You can learn anything.

Question 3

Why is the coronavirus going on in this world is it going to stop or keep on evolving than the first wave of this virus going on?

Accepted Answer

The only virus humans have ever eradicated is smallpox (though two laboratories do still hold some). Given our track record, then, it doesn't seem terribly likely that covid will ever go away completely. Of course it's not completely impossible, so we'll see what happens.

Covid, like all viruses and living things, is always evolving. We tend to notice this when new variants like those from the UK, South Africa, and Brazil come into the spotlight largely because they likely affect the virus's behavior.

Question 6

what is the plant cells

Accepted Answer

Plant cells are cool, and are everywhere.
if you don't believe me, go look at a pear.
If you look closely, then you will see
that these things are rad, to a major degree.
First you have the membrane, they are the gates
made of 2 molecules, glycerol phosphate.
They let good things in, and keep somethings out
with transport proteins, so you don't have to doubt
next the cell wall, the animals don't want
it gives cells their structure, so that they will be taut
If they didn't have them, plants would go keflop
So its a good thing that they do, or they might just be mops
next we have some cytoplasm, helps organelles stay put, 
Keeping things in order, keeps things from afoot
every cell needs it, we cant go without
even clouds have order, or there would be a drought
next we have the chloroplast, so they can get some food,
if they did not have it, it would be so rude
Holding the chlorophyll that will make glucose
in a stack of thylakoid, it has more than dos!
But where comes from the power, to do the 'maizing stuff?
The MITOCHONDRIA, will give powers enough!
It takes all the glucose, from photosynthesis,
and makes ATP, so nothing is amiss.
And where is all the water, that the plants so fast consume?
why, in the vacuole, and holds some waste too!
In plants the vacuole, is larger than we thought, 
Because in animals, we have little or naught.
And now get ready, we saved the best for last, 
because the nucleus, it is rolling past.
With the DNA, so essential to our past.
With all the same bases, we really are connected
to every living thing, that was ever questioned.
I am really tired, but I think it was fun
I really hope you learned, and ignore the pun
(there is no pun, I just needed it to rhyme)

Just so you know, this is all original The Former Wizard Of Oz material. Don't let your eyeballs fall out because it takes so long.🫠

Question 7

If i wanna become a psychologist, what courses would i need to take and learn to reach that goal? (I am in 8th grade right now).

Accepted Answer

Becoming a psychologist involves a journey through several stages of education, each with its own set of courses. Here’s a general roadmap:

Bachelor’s Degree:
 A bachelor’s degree in psychology or a related field is typically the first step. This usually takes four years and requires around 120 credits. Coursework at this level may include:

Introductory Psychological Science
Abnormal Psychology
Psychology of Learning
Developmental Psychology
Multicultural Psychology

Master’s Degree (Optional): Some students choose to pursue a master’s degree in psychology, which provides advanced training in theory, research, and practice. This is not always required, as some students go straight from their bachelor’s degree to a doctoral program.

Doctoral Degree:
 If you plan to become a licensed clinical psychologist, you will need to earn a doctorate in psychology. This could be a Ph.D. (Doctor of Philosophy) or a Psy.D. (Doctor of Psychology), depending on your career goals. The Ph.D. route is typically more research-focused, while the Psy.D. route is more practice-focused.

Internship: Before you can become licensed, you’ll need to complete a supervised internship. This gives you practical experience in your field of interest.

Licensure: Finally, you’ll need to pass your state’s licensing exams to become a practicing psychologist.

Remember, the specific courses and path can vary depending on the specialty area you’re interested in, such as clinical psychology, school psychology, industrial-organizational psychology, forensic psychology, or sports psychology.

It’s also important to note that this is a general guide, and the exact requirements can vary by state and by program. Always check with the specific program and your state’s licensing board to understand the exact requirements.

Happy Learning!

Question 8

Why do we cry? I know how but why

Accepted Answer

There are actually three types of tears. Each type is produced for different reasons, meaning that not all cries are alike.

1. Emotions. The most known reason as to why we cry. Some scientists propose that this is to relieve the body of chemicals that cause stress, as it has been noted that stress hormones are more present in emotional tears.

2. A reflex. If something gets into your eye, your body wants it out as soon as possible to prevent infection or damage. You thus cry what are known as reflex tears. Have you ever got a dust particle or bug in your eye, or chopped an onion (releasing irritating fumes)? Your eyes watered, and you started to cry. You likely did not feel sad or happy, but you still cried. These tears have more water in them in order to flush the object out.

3. Moisturizing your eyes. Yes, your eyes are constantly producing tears, so you are technically crying all the time! However, these tears are there just to lubricate the eye and nourish the cornea. If you had dry eyes, your eyes would get irritated and your ability to see would be reduced.
