Answer:
Chi-square value = 0.6
The difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis.
Explanation:
H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
• Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms
O are the Observed individuals
E are the Expected individuals
• Freedom degrees = 1
• Significance level, 5% = 0.05
• Table value/Critical value = 3.84
The number of observed individuals:
63 have purple flowers, 17 have white flowersTotal number of individuals, N = 80 = 63 + 17
Observed Genotypic frequencies:
F(PF) = 63/80 = 0.79F(pf) = 17/80 = 0.21p² + 2pq + q² = 1
p² + 2pq = F(PF)
0.79 + 0.21 = 1
The expected genotypic frequency:
F (PF)= 0.75
F (pf) = 0.25
The number of expected individuals:
PF= 0.75 x 80 = 60 wf = 0.25 x 80 = 20Chi square = sum (O-E)²/E
PF = (O-E)² /EPF =(63 - 60) ² / 60
PF = 0.15
pf = (O-E)² /Epf= (17 - 20)²/20
pf= 0.45
Chi square= sum ((O-E)²/E) = 0.15 + 0.45 = 0.60
Chi square = 0.6Degrees of freedom = 1 alpha 0.05 Table value/Critical value = 3.840.6 < 3.84 meaning that the difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis. Probably both parentals were heterozygous for the trait.

Explain why siblings may share similarities but are not identical.
Answer:
recombination
Explanation:
Since of recombination, kin as it were share approximately 50 percent of the same DNA, on normal. So whereas organic kin have the same family tree, their hereditary code can be distinctive in at slightest one of the zones looked at in a given test. That's genuine indeed for intimate twins.
Siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.
What is the reason behind a non-identical sibling?Siblings are not identical because each parent can contribute different variations of genes to each child, resulting in unique combinations of genetic material. Moreover, the process of meiosis, which is the formation of reproductive cells, is a random process, meaning that the chromosomes from each parent can mix in different ways during the formation of the offspring's cells. Therefore, each sibling inherits a unique combination of genetic material, leading to individual differences in physical and behavioral traits.
Hence, siblings share similarities because they inherit genetic material from the same two biological parents, who each contribute half of their genetic material to their offspring. Therefore, siblings share a similar genetic makeup, and this can result in some shared physical and behavioral traits.

Hello, I would really appreciate it if you guys could help me answer this, please answer one of the boxes in your own words, I'm in a rush because it will be due tonight.
Answer:
The definition of kinetic energy (also called energy of movement) is a form of energy that an object has which involves motion, and it's a property of a moving object and depends not only on motion but also on mass.
The definition of thermal energy (also heat energy) would be: the energy that's inside of a system that has sole control over its temp.

Which location has the warmer air temperature: Tarapoto or Neuquén? Why?
view the pic below.
Answer:
Palmas is closer to the equator than Neuquén. Which location has a warmer air temperature.Neuquén, because more energy is transferred from the sun directly to the air. Neuquén, because more energy is transferred from the sun directly to the surface, and then from the surface to the air.
Answer:
The climate in Tarapoto is hot, muggy, and mostly cloudy. Over the course of the year, the temperature typically varies from 70°F to 94°F and is rarely below 67°F or above 98°F.
And that is why the neuquen has the warmer air temperature!

Membrane proteins offer structural support to the membrane but have no other function. Both plant and animal cell membranes are considered fluid mosaics.
Answer:
- In water, phospholipids spontaneously arrange into a bilayer
- Steroids in cell membranes allow the membrane to be more fluid
- Phospholipid bilayers surround all eukaryotic cells
- Both plant and animal cell membranes are considered fluid mosaics
Explanation:
All living things (i.e.. both eukaryotic and eukaryotic organisms) are composed of cells, and all cells have cell membranes. In an aqueous environment, phospholipids spontaneously form bilayers: hydrophilic heads of phospholipids face the water environment at the surface of the bilayer, while hydrophobic fatty acid chains are shielded from the water in the interior. Steroids are lipids that intercalate into the bilayer of the cell plasma membrane, reducing the fluidity of the membrane. Integral membrane proteins may have different biological roles. For example, permeases are integral membrane proteins that facilitate the diffusion of certain molecules (e.g., glucose) across the cell membrane by passive transport. Both plant and animal cell membranes are considered fluid mosaics where different types of molecules (e.g., phospholipids, cholesterol, proteins, etc) are constantly moving across the membrane.

List 3 ways that microwaves are beneficial to society
1. It’s a super-fast way to get a (healthy) dinner on the table.
2. Despite what you’ve heard, it’s perfectly safe.
3. It can help migraine sufferers.
1. It’s a super-fast way to get a (healthy) dinner on the table.
For some reason, when most of us think of microwaves, we think of unhealthy (and not-so-tasty) frozen microwavable dinners. But they’re good for so much more than that! Aside from reheating leftovers, you can also use a microwave to make a tender baked potato in just eight to 10 minutes and steam veggies in two minutes with very little cleanup. You can even use it to heat up whole grains and healthy proteins. Not only does it get dinner on the table quickly (no oven preheating or waiting for pressure to release), but it’s especially great this time of year when it’s too hot to even think about turning on the oven. Beyond dinner, I use my microwave regularly to heat up oatmeal in just a few minutes and heat up non-dairy milk for quick lattés.
2. Despite what you’ve heard, it’s perfectly safe.
For several years, I admittedly avoided microwaves because I’d heard myths about dangerous toxins flying through my kitchen and other health claims. Now, I laugh about this.
After doing some digging, I’ve found that many studies confirm that microwaves are more efficient at retaining nutrients than other methods — especially roasting at high temperatures, something most all of us feel safe doing in the oven. Another important fact: Most of us are exposed to more radiation through our cell phones each day than we are with one or two sessions a day of simple microwave use.
Also, no studies to date have found that microwaves cause cancer or any other major disease in humans. The tests that do link microwaves to cancer and neurological issues have only been performed on rats — not humans — which can’t be equally compared and shouldn’t be.
The most important thing to remember when using a microwave is to skip the plastic containers. Old plastic containers could have BPA, and that can leach into our food when the plastic heats. Even if you have new plastic, why not just use glass?
3. It can help migraine sufferers.
I do not suffer from chronic migraines, but I know plenty of people who do — and many of them say that their microwaves are key to helping them manage their pain. See, there are these little bags that can get heated up, and they almost provide instant relief. Yes, you can heat these bags in the oven, but then you have to wait for the oven to heat up and then for the bag to heat up. With a microwave, you just nuke the bag for two minutes and you’re in business
