Determine which type of transport is being depicted below

Biology
1 answer:
irinina [24]3 years ago
3 0

Answer:

Active transport

Explanation:

The molecules are moving from a low concentration to a high concentration across a cell membrane via a protein. ATP is used in this reaction.

We know it cannot be diffusion, facilitated diffusion, passive transport, or osmosis, because these are all passive processes. In the picture, the molecules are moving against their concentration gradient and uses energy.

It cannot be endocytosis or exocytosis, as there are no vesicles.

Active transport is the movement of molecules from a low concentration to a high concentration across a cell membrane against their concentration gradient. ATP is used to supply the energy for this process.

Explain why protecting surviving rainforests from deforestation is important to fighting cancer.
Rufina [12.5K]
<span>Some 120 prescription drugs sold worldwide today are derived directly from rainforest plants. And according to the U.S. National Cancer Institute, more than two-thirds of all medicines found to have cancer-fighting properties come from rainforest plants. Examples abound. Ingredients obtained and synthesized from a now-extinct periwinkle plant found only in Madagascar (until deforestation wiped it out) have increased the chances of survival for children with leukemia from 20 percent to 80 percent.</span>

¿Por qué las bacterias resistentes se multiplican más rápido después de que un paciente ha tomado antibióticos en comparación co
Fofino [41]

Answer: In Spanish

¿Cómo se vuelven resistentes las bacterias a los antibióticos?

R: Las bacterias pueden volverse resistentes a los antibióticos de varias maneras. Algunas bacterias pueden "neutralizar" un antibiótico cambiándolo de una manera que lo hace inofensivo. Otros han aprendido a bombear un antibiótico fuera de la bacteria antes de que pueda causar algún daño. Algunas bacterias pueden cambiar su estructura externa, por lo que el antibiótico no tiene forma de adherirse a la bacteria que está diseñada para matar.

Después de exponerse a los antibióticos, a veces una de las bacterias puede sobrevivir porque encontró una manera de resistir el antibiótico. Si incluso una bacteria se vuelve resistente a los antibióticos, puede multiplicarse y reemplazar todas las bacterias que fueron eliminadas. Eso significa que la exposición a los antibióticos proporciona una presión selectiva que hace que las bacterias sobrevivientes sean más propensas a ser resistentes. Las bacterias también pueden volverse resistentes a través de la mutación de su material genético.

Answer in English :

How do bacteria become resistant to antibiotics?

A: Bacteria can become resistant to antibiotics through several ways. Some bacteria can “neutralize” an antibiotic by changing it in a way that makes it harmless. Others have learned how to pump an antibiotic back outside of the bacteria before it can do any harm. Some bacteria can change their outer structure so the antibiotic has no way to attach to the bacteria it is designed to kill.

After being exposed to antibiotics, sometimes one of the bacteria can survive because it found a way to resist the antibiotic. If even one bacterium becomes resistant to antibiotics, it can then multiply and replace all the bacteria that were killed off. That means that exposure to antibiotics provides selective pressure making the surviving bacteria more likely to be resistant. Bacteria can also become resistant through mutation of their genetic material.

I don't know if this help you at all.

if an unknown substance found on a meteorite contains no trace of carbon can scientist conclude that there is life at the meteor
MakcuM [25]

The scientists rely on the following cues to hypothesise and test for the presence of life on various extraterrestrial bodies:

1. Presence of water

2. Presence of hydrocarbons

3. Presence of carbon

4. Presence of salt pans  

The presence of hydrocarbons may indicate that there's anaerobic life thriving beneath the surface of the meteorite. The presence of traces of carbon may indicate that there was life once thriving on its surface ( which however is not possible in case of a meteorite because of its size). The absence of any of the above listed items will indicate that the surface of the meteorite is devoid of any life.

. Describe the structures of proteins and nucleic acids, and then explain the relationship between these two molecules within a
Snowcat [4.5K]
<span>Proteins are large biomolecules that are made up of long chains of building block molecules called amino acids. Each amino acid folds to form a protein with a specific cellular function.

Nucleic acid is basically DNA & RNA. DNA is the genetic information that contains all the information one needs to live. RNA stands for ribonucleic acid and has a variety of roles.

When comparing them, they actually don't look at all similar when looking at the large molecules or the 'building blocks'. But, they're both made up of mostly carbon, nitrogen, hydrogen and oxygen. The elements mentioned are assembled in different ways for both Proteins & Nucleic acid. The major similarity between them is that with the protein production DNA and RNA contain all the information that a cell uses to make protein.

</span><span>Their overall interactions can be summed up by the central dogma of molecular biology:

DNA --transcription--> RNA --translation--> Proteins
