Can someone explain the Punnett square ?
Answer:
so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB. next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.
Explanation:
the main points.
in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.add me and message me if you need more help. we can also zoom to figure it out.

What absorbs water in the digestive system
Your answer is Small Intestine.
Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Answer: Small intestine
Either you put small intestine in the wrong place, or you're able to put the same one for multiple questions

True or false scientific name tells you to family in which the organism belong
Answer:
False
Explanation:
A scientific name for a species is a unique name, which means that no species can have the same scientific name. The scientific name of a species tells you the genus and the species name of an organism. The genus comes first in the name and is the more inclusive group of organisms.

A coolie of 40 kg weight carries 20 kg salt and climbs up 20 steps of 20
centimeters each in 2 minutes. Calculate the work done by him and his power.
[g= 10 m/s2)
ma
OW
Explanation:
Given
mass of coolie = 40 kg
Mass of salt = 20 kg
Total mass (m) = 40 + 20 = 60 kg
Displacement (h) = 20*20 = 400 CM = 4 m
Work done (w) = ?
Power (P) = ?
We know we have the formula
work done =force × displacement
or work done = m * g * h
work done = 60×10×4
work done = 2400 joules
Similarly
power = work/time
power = MGH/time
power=60×10×4/120
power=2400/120
power= 20watt

What is a similarity and a difference between the stars Rigel & Betelgeuse?
Stars as large as Betelgeuse are very unusual. In contrast, Rigel, the bright, bluish-white star at the southwest corner of Orion, is smaller and much hotter than Betelgeuse. Although Rigel is smaller than Betelgeuse, it is still a super-giant star compared to the sun.

Light-dependent and light-independent reactions occur at the same time. True or False
true because they are driven by the ATP made by the light-dependent reactions. Both systems shut down in the dark. The light-independent reactions can last a little longer if there is ATP remaining in the chloroplast.

What is a recessive allele?
Answer:
A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.
Explanation:
Answer:
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. An allele is a specific variation of a gene, or specific segment of DNA. Different alleles produce slightly different proteins, which function in different ways.

Predict the effect on shrubs growing in one area if they are treated with a compound that blocks electron flow through the electron transport chains of chloroplasts. Provide reasoning to justify your prediction.
Answer:
The shelves or die and will not be able to produce sugars. Blocking electron flow prevents the formation of the proton gradient required to produce the ATP used for sugar production.
The shrubs will die because they cannot photosynthesize. Without it, plants begin to wilt and finally die because photosynthesis requires light.
In the absence of photosynthesis, do plants die?In essence, photosynthesis is the mechanism that powers the survival and growth of plants and even algae. The majority of plants would perish quickly if photosynthesis suddenly stopped.
Night-time is not a time when plants engage in photosynthesis. Only when exposed to the right wavelengths of artificial light during the night can plants perform photosynthesis. Light energy is absorbed with the aid of the pigment chlorophyll. Light energy is converted into chemical energy through the process of photosynthesis.

Which benefits do mangrove trees provide to surrounding coastal wetlands? Check all that apply.
1 . They hold soil in place.
2 . They store floodwaters.
3 . They maintain surface water flow.
4 . They filter water and improve water quality.
plz help people! :) :( :/ :}
i dont know what to dooo!
Answer:
1, 2, and 4
Explanation:
1. They hold the soil in place because of their tangled root infrastructure
2. They safeguard the shores from storms, floods
4. They sustain the clarity and quality of water, trapping the sediments and filtering pollutants arising from the land
As scientists advise about potential risks due to climate change, many coastal areas are preparing for a higher risk of impact Predict
which of these has a greater impact on human health in coastal areas due to climate change.
Since the coast water is rising,it would be hard to find fresh water. The people would not be able to use the water,because it would be contaminated with bacteria. If all of the ice does melt,most of the fresh water will turn to salt water,and we would have to adapt to a new way of life. People would have to live on higher land,there would be no one to grow crops,and their would be no way that trees would survive,meaning we would not be able to breathe.The worst part of this all is that the Earth's temperature will sky rocket,and it will be so hot,the Earth will kinda be like a huge hurricane.(lol)

How could one determine if two
unidentified organisms share a common
ancestor?
Answer:
Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.
Explanation:
DNA
They can look at the DNA it's the most common one.
There are 4 pieces of evolution and they are
Fossils , Geography , Embryos / DNA , Anatomy
Fossils: Physical remains of species , Determine age, location, environment
Deeper layers = older
Geography: Proves species share common ancestors, depending on where
they live
DNA: BEST evidence because it’s the MOST ACCURATE
Similarities in the early stages of development
Similarities in DNA
More similarities = closely related
More differences = not related
Anatomy: Compare body parts of different species to see how they evolved
3 different structures:
Homologous (same structure, different function)
Analogous (similar structure, different organisms)
Vestigial (body parts that no longer serve a purpose)
All of that are in evolution
