Answer:

Lactic acid is accumulated in the muscles which is causing burning muscle pain.  

Explanation:

During intense exercise our muscles shifts to anaerobic mode of ATP generation. So in anaerobic respiration muscles do not use oxygen but use lactic acid fermentation for energy production which don require oxygen.  

In lactic acid fermentation, the pyruvate produced during glycolysis is used and converted into lactic acid. The accumulation of lactic acid in the muscle causes the burning muscle pain during the peak of high-intensity physical training and after the training.  

Therefore lactic acid is accumulated in the muscles which is causing burning muscle pain.

When considering the evolutionary tree of life and the three domains of life, which statement best describes what likely happene
Fudgin [204]

Answer:

The answer is - Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Explanation:

The options are:

A. Bacterial and eukaryotic cells are more closely related to  each other than to archaeans, as evidenced by the fact that  bacteria and eukaryotes do not inhabit the most extreme  environments.

B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

C. Bacteria and archaeans are more closely related to each other  than to eukaryotes, as evidenced by their cell structures. Bacteria  and archaeans are prokaryotic, while all eukaryotic cells contain  mitochondria and other membrane-bound organelles.

D. The three domains of life are equally divergent from one  another, so no two domains are more closely related to each other.  This is supported by the evolutionary tree of life because three  branches extend from one node millions of years ago.

The answer is - B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Archaea and bacteria are similar in terms of cellular organisation and size but are however similar to eukaryotes (eukarya) at the molecular level. Archaea and Eukaryotes both undergo DNA replication and protein synthesis the same mechanism. Both of them posses closely related genes and several metabolic pathways, including the enzymes in transcription and translation.

A drug binds to a receptor in the nucleus. This binding turns on a gene to make a protein. This drug is ____. lipophilic and hyd
Serjik [45]

The drug that to a receptor in the nucleus. This binding makes on a gene to make a protein. This drug is actually lipophilic and hydrophobic, the correct option is A.

What is receptor?

In biochemistry and pharmacology, receptors are protein-based chemical frameworks that transmit and receive signals that can be assimilated into biological systems.

As the drug is crossing the lipid membrane so it should be lipophilic and hydrophobic to be able to bind the receptor as in the given situation.

Thus, the correct option is A.
