summarize what biogeography is and an example for it
IN YOUR OWN WORDS
Explanation:
The study of how plants, animals, and organisms are spread across the globe over time and space is known as biogeography.
Example of biogeography includes the splitting of Pangea (all the Earth's continents were one large landmass).
You created three different derived strains from E.coli K12. One strain includes a deletion in a gene critical for biosynthesis of diaminopimelic acid, one strain lacks dnaQ, and the last strain lacks both. Describe experiments to clearly differentiate between these three strains through phenotypic assays alone (not just by sequencing the genomes or any derivative of genotyping). Include all necessary controls to interpert the experiment.
Answer:
For the strain that lacks DNAQ there will be slowed growth and there will more DNA breakage by Tunel assay
For the strain that lacks both The cells there will have a huge DNA breakage and less peptidoglycan.
Explanation:
One of the experiments that can be used to differentiate diaminopimelic acid is by observing the cell walls in which they are present because are needed in the formation of cell walls. while to differentiate the three strains
For the strain that lacks DNAQ there will be slowed growth and there will more DNA breakage by Tunel assay
For the strain that lacks both The cells there will have a huge DNA breakage and less peptidoglycan.

George and Kyle were taking a quiz. This was item four:
Scientists just discovered a new kind of organism and gave it the common name blue spinner. Make one statement that must be true about the structure of a blue spinner.
George wrote, "A blue spinner is made of at least one cell."
Kyle wrote, "A blue spinner has tissues that perform specific functions."
Which of the responses is correct? Explain the error made in the incorrect response.
Answer:
George Is correct.
A blue spinner is made up of at least one cell.
Explanation:
George and Kyle took the quiz about the new kind of organism. The characteristics of this organism is not known as it has just discovered. George statement can be true about blue spinner as all living organism are made up of at least one cell. The blue spinner can be unicellular or multicellular organism which will be discovered later by scientists.
An individual way of life can be either unicellular or multicellular is called an organisms. It is a single entity that functions to live and survive.
The statement made by George is correct.
According to George blue spinner is made up of at least one cell. For an organism to be living it has to be composed of either one cell or multiple cells.As the new species discovered can be either multicellular or unicellular.Kyle's statement is incorrect as it is known whether the organism is a single or multi-celled structure as the deduction about tissues cannot be made.Therefore, George is correct and Kyle's is incorrect.

Answer:
Riñones.
Explanation:
Los riñones son dos órganos ubicados en la cavidad abdominal detrás del peritoneo, a la izquierda y derecha de la columna. Los riñones tienen la función de mantener constante la composición de la sangre, eliminando así las sustancias no deseadas disueltas, como los productos de desecho del metabolismo y los venenos y medicamentos absorbidos a través de los alimentos. El riñón también mantiene el equilibrio ácido del cuerpo a largo plazo, mediante el transporte de carbonato de hidrógeno e iones de hidrógeno. El producto que producen los riñones, una solución de sustancias que el cuerpo ya no puede usar, se llama orina.

Organisms provide people with jobs and the things they need to live that gives them _____ value?
A economic
B niche
C ecological
D recreational
Answer:
Organisms provide people with jobs and the things they need to live that give them economic value
Explanation:
Natural resources might are the supplies of any economic activity carried out by humans. It is not possible for humans to live with no natural resources because it would mean a stop in production, hence in feeding, and finally, it would lead to death.
Natural resources lack a price because there is no market to interchange them. However, they have an economic value to humans because they are the base of any economic activity, keep a balance in nature, and depend on each other. Any alteration of the natural equilibrium of the environment means a disbalance in the economy. Then it became necessary to estimate that value or use an indicator of its importance for social welfare. It is about making an economic valorization of the environment.
Economic value refers to the quantification of the value of natural resources. It is the economic importance of natural resources for the satisfaction of human needs. The value determined for natural resources is based on the explicit or implicit, factual or potential exploitation of resources.
It is basically about putting a quantifiable value on natural resources according to their social benefits.
Some natural resources represent an actual price in the economic market, while others do not, but that have many other benefits.
The economic value might be determined by "the use-values" (direct or indirect uses associated with the market) and to the "not use-values" (the values for future use, a potential use, and the intrinsic value of resources existence).

Explanation:
In a separate line of experiments, you are studying a protein that you suspect shuttles between the nucleus and the cytoplasm. However, when you localize a GFP-tagged fusion protein, it appears to be only in the nucleus. To test whether it shuttles, you set up a heterokaryon assay. You take a cell expressing the GFP fusion protein and partially fuse that cell with another that does not express the GFP protein. The result is a heterokaryon that has a single cytoplasm but two separate nuclei. You treat the heterokaryon with the translation inhibitor cycloheximide for several hours and then examine the localization of the GFP protein. What do you predict will be observed if the GFP protein shuttles between the nucleus and the cytoplasm
Answer:
Following are the responses to these question:
Explanation:
The heterokaryons were cells of diverse traditions or more nuclei. A heterokaryon cell with network cells (donor and receiver nuclei) sharing a common costly to treat is produced whenever a node containing GFP-tagged protein (donor cell) is merged to a cell non express the GFP-tagged proteins (recipient cell). Unless the intracellular scram nuclear exists, GFP must leave the GFP atoms, be shipped to the cytosol, and be exported to a nucleus with emission of GFP protein (recipient nucleus). It is obtaining nuclear has been beginning to release the GFP protein.
Unless the GFP protein doesn't display a nucleus costly to treat, this is not distributed across time in the metal target. By either sole dissemination through nuclear pores or receptor-mediated routes, protein yelling from nuclear to emotional exhaustion can occur. That GFP proteins are shown in a nucleus only suggests a path via a transmitter. For chloroplast, though, protein disperses via nuclear envelope. It is not the case. It should have nuclear foreign trade signals when ferrying between the nucleus and cytoplasm.
Cycloheximide is indeed a medicine that stops protein expression without elongating. For heterokaryon cells, it inhibits fresh protein synthesis. It makes visualization of a nanoparticle cell of only old pre-existing molecules (before cycloheximide diagnosis). That post GFP substance is a shuttling shielding substance that passes seen between the nucleus and the cytoplasm and the receiver nucleus. Whenever the levels of the shuttle were high, the GFP protein expression is shown both by the sender and receiver nucleus. The recipient nucleus will not be left without any schlepping protein. Thus, the donor nucleus can only be used.

How did Darwin disprove Lamarck? Explain why Darwin still thought that Lamarck’s idea was very important.
Lamarck's theory was disproved by Darwin's theory of natural selection which says only favourable genetic variations are passed on from parents to offspring. But, according to Darwin, Lamarck's idea was important because almost all organisms become complex with evolution.
What were Lamarck's and Darwin's theories? According to Lamarck, all-natural variations that occur within an organism are passed on from generation to generation. The organisms become complex with time and simple organisms get disappear or extinct. But, according to Darwin's theory of natural selection, the variations that are beneficial for the survival of organisms are passed on from generation to generation. This natural selection leads to evolution that helps in the long survival of some selected species. If the organisms are not adapted or changed to their surrounding conditions, then they extinct. More complex organisms have more chances of evolution than simple organisms. This means that with evolution, organisms become complex.Thus, Darwin disproved Lamarck's theory as all variations are not passed on. But, he still thought that Lamarck's idea was important as with evolution, organisms become complex to ensure their survival.

. What structure in amoebas aids in phagocytosis?
Answer:
Explanation:.Amoebas and some other heterotrophic protist species ingest particles by a process called phagocytosis in which the cell membrane engulfs a food particle and brings it inward, pinching off an intracellular membranous sac, or vesicle, called a food vacuole.In amoebas, pseudopods are used to surround the targets for phagocytosis the surrounding particles kill the particle and use their useful products.
What is phagocytosis?Phagocytosis happens in certain organisms, such as amoeba, by surrounding the target particle with pseudopods, as in animal phagocytes. Entamoeba histolytica, an amoebozoan, can phagocytose red blood cells in animals.
The engulfed item is therefore confined within a phagosome, a membrane-bound vacuole. The phagocyte digests the ingested particle utilizing hydrolytic enzymes found within the cell's membrane-enclosed sacs called as lysosomes.
All amoebae get an amoeboid lifestyle (the ability to alter cell shape by extending and retracting pseudopods), and most amoebae are professional phagocytes that feed on microbes such as bacteria via phagocytosis.
Therefore for engulfing surrounding the target particle amoebas use pseudopods.
