The answer is bladder control usually is achieved before bowel control.
Bowel control usually is achieved before bladder control. The child should not be forced to sit for long periods . The ability to remove clothing is one of the physical signs of readiness for toilet training. The physical ability to control the urethral sphincters is achieved some time after the child is walking, probably between the ages of 18 and 24 months.
In the average person, 70-80 percentage of alcohol is absorbed through the small intestine.
- Alcohol is not treated the same way as other food nutrients. In fact, the digestive system exerts additional effort to remove it from the body, giving alcohol removal priority over other nutrients including lipids (fats), carbs, and proteins.
- All parts of the digestive tract take in alcohol. In contrast to other nutrients, alcohol is quickly absorbed in the small intestine and enters the bloodstream immediately via the stomach lining.
- Although other bodily cells can also metabolize alcohol, the liver is where alcohol metabolism mostly takes place.
- Acetaldehyde, a poisonous chemical, is created when alcohol is broken down.

Answer:
The same gene encodes both proteins by using different combinations of exons in the pre‑mRNA via alternative splicing.
Explanation:
According to the question, two different proteins (one with 56 amino acids and the other with 82 amino acids) are found to be encoded by the same gene. This is possible due to a process called ALTERNATIVE SPLICING.
Alternative splicing is a phenomenon whereby the protein-coding region of a gene called EXON is manipulated in such a way that variety of proteins emanate from a single gene. This manipulation includes the removal or inclusion of EXONS in the gene, so as to give rise to different combinations of mRNA, hence, different proteins will be translated from the different mRNA from the same gene.
In this case, exons were removed from one mRNA to have lesser amino acids (56) in the translated protein while exons were included in the other mRNA to have more amino acids (82).
Answer:
Without enzymes, chemical reactions would not occur quickly enough to substain life.
Explanation:
The correct answer iare A. All organisms have had one common ancestor in the past, and C. Gorillas share an extinct ancestor with bonobos.
Explanation
The image shows an evolutionary tree that resulted in species such as the chimpanzee, orangutan, gorilla, bonobo, and humans. This tree shows nodes, which are the points shown on it. These nodes represent an extinct species as a common ancestor of the species of the next node that are connected to it. Therefore, the correct answers are A. All organisms have a common ancestor in the past, this statement is true because all the species shown in the tree are the result of different divisions of a first species that lived 13 million years ago. The second correct statement is C. Gorillas share an extinct ancestor with bonobos. Because in the graph it can be seen that 6 million years ago there was a node/species that is the common ancestor of the gorilla and the bonobo.
