Biology > Cell biology > Passive transport
There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).
Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).
Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.
Answer:

Answer:
<h2>Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.</h2>

The correct statement is that the ribozymes may function in RNA splicing.
Non-proteinaceous RNA enzymes are known as ribozymes. They function as molecules that catalyze reactions in which RNA is the catalyst. Within the nucleic acid molecules, these molecules have the capacity to both break and create covalent bonds. RNA splicing may be facilitated by ribozymes. Despite having a small chemical repertoire, they have a wide range of biological functions and are essential for the three kingdoms of life. They are involved in the maturation of transfer RNA, intron splicing, the replication of RNA viruses or viroids, the control of messenger RNA stability, and protein synthesis.
