Answer:
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

The breaking of a large organic molecule into smaller individual subunits involves multiple ________. dehydration synthesis reactions osmotic reactions hydrolysis reactions hydrosynthetic reactions
Answer:
hydrolysis reaction
Explanation:
Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro" = water and "lysis" = break) involves adding water to one large molecule to break it into multiple smaller molecules.

(b) The pGoG protein is known to block the G, to S transition in the cell cycle. Explain why this prevents
miosis from happenina in he cell
(c) Before treating melanoma cells with capsaicin, researchers pretreated the cells with an inhibitor of
calcineurin. Predict the effect of this pretreatment on the ability of capsaicin to induce apoptosis by the
pathway shown in Figure 2. Provide reasoning to justify your prediction.
(d) Researchers claim that many cancers include a mutation in the gene encoding pGoG. Support the
researchers claim.
Answer:
Explanation:
c. The pretreatment on the ability of capsaicin to induce apoptosis effects in NFAT2 to block ATF3 where it activates ATF3 to inhibit pGoG from inducing apoptosis.
d.AFT3 usually stops pGoG from induce apoptosis and so cancer develops because of apoptosis unable to do it's job and cells just keep dividing which we call a tumor

Complete the Punnett square
1) BbEE
2) BbEe
3) BbEe
4) bbEe
The Punnett square is a diagram used to predict the genotypes of a particular breeding / etc. For example, in the top left BE and BE becomes BBEE because you take both letters and put them together. Here, the Bs will go first and the Es. In the one to the right of that, Be and BE becomes BBEe as you put the Bs and Es in order, but you also have to make sure that lowercase bs go after uppercase bs, and etc.

How toxins are accumulated as you go up in trophies levels in an ecosystem
Answer:
hi sorry, i want stitches

This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others
The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.
In the ecosystem, the living and non-living things interact over time leading to exchange of energy.
A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.
The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).
The energy flow is indicated with an arrow thus,
grass ---> rabbit -----> wolves.
Food chain, therefore includes linear sequence of organisms.
Food web on the other hand illustrates a complex feeding relationship within the ecosystem.
The food web is made up of a prey that can be eaten by more than one predator.
Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

What happens if a cell is unable to divide by mitosis
Answer:
When this happens, sometimes the cell commits a special type death is called apoptosis. Apoptosis, otherwise known as programmed cell death, ensures that if mitosis goes wrong and cannot be fixed, the cell does not continue to divide, as this would lead to the production of mutant cells that might cause problems.
