Answer:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

help I can't think of any for this question "State 5 different ways animals and plants interact in an ecosystem."
Oksana_A [137]

Answer:

Plants and animals benefit each other as members of food chains and ecosystems. For instance, flowering plants rely on bees and hummingbirds to pollinate them, while animals eat plants and sometimes make homes in them. When animals die and decompose, they enrich the soil with nitrates that stimulate plant growth. I know it's not 5, but I hope it helped.

Use the numbers to put the steps of translation in order, from first (1) to last (5). The large ribosomal subunit completes the
pashok25 [27]
Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, <span>the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, </span><span>amino acids are paired with anticodons, gradually forming a long chain</span>; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.

​the symptoms of ____ are caused by progressive demyelination of nerve cells in the brain and spinal cord. ​multiple sclerosis ​
nika2105 [10]

The correct answer is multiple sclerosis.

The MS or multiple sclerosis refers to a demyelinating disorder in which the insulating envelopes of the nervous tissues in the spinal cord and the brain get destructed.

This destruction disturbs the tendency of the components of the nervous system to interact, leading to an array of symptoms and signs, involving mental, physical, and on certain occasions psychiatric issues.
