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.

Answers

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)

Simple and easy but three sources are:
1. Decomposition
2. Ocean Release
3. Respiration

Answer:

Yes, there are natural sources of atmospheric carbon dioxide, such as outgassing from the ocean, decomposing vegetation and other biomass, venting volcanoes, naturally occurring wildfires, and even belches from ruminant animals.[1]

Can someone explain the Punnett square ?

Answers

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.

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

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.

Answers

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.

What absorbs water in the digestive system

Answers

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.

centimeters each in 2 minutes. Calculate the work done by him and his power.
[g= 10 m/s2)
ma
OW​

Answers

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

How could one determine if two
unidentified organisms share a common
ancestor?

Answers

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
