Scientists at the tar pits discovered that many of the smaller animals they extracted from the pits still exist around Los Angel

es today. But many of the larger mammals—such as woolly mammoths and saber-toothed tigers—are now extinct. Why do you think this is the case? What can scientists learn about Los Angeles’ climate history by studying the specimens found in these tar pits?

Answer:

They can infer that it used to be very cold because woolly mammoths and saber tooth tigers used to live in these climates. They might have went extinct because since they are bigger, they didn't have a very big population to begin with, unlike the smaller animals that survived and have now adapted

Answer:

It looks to me that those are plant genes. And plant genes use the atmosphere and the hydrosphere to take in carbon dioxide. CO2 is in the atmosphere and once consumed, sugar ( Glucose ) is created. H2O is part of the hydrosphere and when water is consumed, Oxygen is the output. All of the spheres of the earth ( biosphere, hydrosphere, geosphere, and atmosphere ) are interconnected to create the things we know and see.

Place the steps involved in the process of bacterial transformation in the correct order. Drag the labels to the appropriate loc
igomit [66]

Answer:

The flowchart is not seen in your question. The labeling cannot be done without seeing the flowchart.

Here are the processes of bacterial transformation:

Explanation:

Bacterial transformation is defined as the change in the properties of bacteria which is caused by the introduction of foreign and naked DNA.

DNA is an hereditary material in organisms that contains their genetic information.

Here are the processes of bacterial transformation:

Step 1: Donor cell forms a Donor cell lyses

Step 2: Donor cell homologous binds to a receptor site on the recipient cell.

Step 3: One strand of donor cell DNA is degraded, and transformed DNA Pairs with homologous region on recipient cell.

Step 4: Finally, recombines with recipient cell chromosome

Which statement is true of both active transport and facilitated diffusion?
enyata [817]

The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.

Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.

Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.

Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
