carnivorous plants example .pls I need it now . I will mark brainlest.
Answer: the Darlingtonia californica ( california pitcher plant ) the california pitcher plant is a carnivorous plant that it lures, traps, and dissolves insects with its pitcher shaped leaves. Insects are lured to the slippery pitchers by color and nectar. Once the insect enters the bulbous top of the pitcher it becomes disoriented by the translucent quality of the leaves.
Suggest why energy from the sun flows in one direction while materials are cycle within an ecosystem
Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.

One of the concerns about rising CO2 levels ocean water is the negative effect on certain types of marine life, such as oysters and clams. Does your experiment show a negative effect? Explain your answer.
Answer:
see below :)
Explanation:
For many years sea life such as oysters and clams have been acostumed to the temperature of the water. Rising levels of CO2 will cause more heat in water temperatures. This would make the shells of the oysters and clams 'wear away'.
Answer:
yeah the person under me is right
Explanation:
Ocean acidification is a consequence of the excess carbon dioxide in the atmosphere from fossil fuels. When the ocean absorbs the CO2, the water becomes more acidic. Shelled animals like zooplankton, corals, clams, mussels and oysters cannot grow their shells in the acidic water.

How does your model show what happened to the circled rock material as a result of plate motion?
Answer:
Once exposed, they are weathered, both physically (by mechanical breaking of the rock) and chemically (by weathering of the minerals), and the weathering products — mostly small rock and mineral fragments — are eroded, transported, and then deposited as sediments. Therefore, the model should show signs of deterioration and subduction.
Explanation:
I'm not sure if this is on a quiz or test, but this is what I would put down. No need to mark me brainliest, thanks anyway! :)
If water is being extracted from an underground aquifer at a lower rate than precipitation is replenishing the aquifer, then the aquifer will eventually fill beyond
capacity.
True
False
Answer:
True
Explanation:
If precipitation occurs more frequently and it precipitates more than what is being extracted, it will eventually fill beyond capacity.

C - heated water from nuclear power plants are deposited into the aquatic ecosystem.
Which statement below applies to the evolutionary thoughts of Lamarck ONLY?
Organisms evolve over time
There are variations in populations which causes those that are best adapted to
live and reproduce successfully.
The most fit organisms survive to pass along beneficial these traits to their
offspring, resulting in more individuals each generation having the desired trait
Organisms acquire traits they need and then pass down these acquired
characteristics that they had obtained in their lifetime to their offspring.
Answer:
The most fit organisms survive to pass along beneficial these traits to their
offspring, resulting in more individuals each generation having the desired trait
Explanation:
why is earth's crust necessary for any life to take hold on our planet
Answer:
I think is this
Explanation:
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It's also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.
What are gametes? How are gametes different from regular body (somatic) cells?
Answer:
Gamtetes are sex cells, for humans, this manifests as the sperm cell and the egg cell.
Explanation:
Gametes are haploid cells unlike most of our body cells that are diploid cells.
True or false. Can you provide any evidence?
1. When species come into contact with closely related species, they interbreed and become one species again
2. Medium ground finches with relatively large beaks tend to have offspring with relatively large beaks
3.Birds with a beak type poorly shaped for the current environment are able to adapt by changing their beak types
4. Speciation, or the evolution of new species, in Galapagos finches results because natural selection favors different beak types on different islands.
False When species come into contact with closely related species, they interbreed and become one species again.
What process lead to the speciation of the Galapagos finches on the different islands?
All of them grew from one progenitor species, which inhabitated the islands only a few million years ago.
This process, whereby species develop rapidly to use empty ecospace, is called as adaptive radiation.
Thus, its false, When species come into contact with closely related species, they interbreed and become one species again since its an example of evolution.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
The amino acids which are encoded by the following codons are UUC- Phenylalanine, UCU- Serine, and CUU- leucine amino acid.
What are codons?
A codon is a DNA or RNA sequence which is made up of three nucleotides that forms a unit of the genomic information that encodes for a particular amino acid or signaling the termination of protein synthesis i.e., stop signals in a cell. There are about 64 different codons of which 61 specify amino acids and 3 are used as stop codons that terminate translation process. The 61 codons codes for 20 amino acids in the human beings.
The codons given in this case encodes for different amino acids which are UUC encodes for phenylalanine, UCU encodes for serine amino acid, and CUU encodes for leucine amino acid.

4.This photograph was taken in 2004, 24 years after Mount Saint Helens erupted. Compare and contrast this photo with the previous three. What changes do you see in the biotic and abiotic factors? Does anything surprise you about this series of photographs?
Answer:
In this picture the ground is now completely covered in vegetation and trees are growing back all along the road and sides of the picture. Then there’s little flowers and grass and bushed all over the place. In the other pictures the ground was bare, with the second and third pictures having bushes and other little vegetation starting to grow. Changes in the Biotic Factors: There are now larger trees, there is grass, flowers, small bushes, and other small vegetation growing. Changes in Abiotic Factors: The ground is no longer dust and ash, The dead trunks and branches are covered in vegetation for the most part and are decomposing.

WILL MARK BRAINLIEST Identify 2 organisms that would have a decreased food supply if insects were removed from the food web,
Answer:
Frogs and voles would have less food supply.
Explanation:
There would be more food for the rabbits and slugs, so their populations would increase. However, ( there would be less food for the frogs and voles), so their populations would decrease. This means less food for the foxes and hawks. However, there are likely to be more rabbits and thrushes for them to eat, so their populations might stay the same.
