Explanation:
Without the skeletal system, the body could not carry oxygen in the blood. The given statement is true.
What is skeletal system?
The skeletal system in the body is composed of muscle tissue, ligaments, and bone. It is in the bone marrow that hematopoiesis (development of blood cells) occurs. These hematopoietic stem cells (HSCs) from red bone marrow differentiate into erythrocytes, platelets, and lymphocytes. Bone marrow is found in the connective tissue interior of bones.
In a healthy person, the concentration of oxygen also called O₂ saturation in arterial blood is in the order of 97 and 100%, both at rest and during exercise.The concentration of oxygen in blood is a parameter that depends on proper respiratory function, and varies according to whether the blood is arterial or venous, where this percentage is lower.
Therefore, Without the skeletal system, the body could not carry oxygen in the blood. The given statement is true.

We're given that the mass of the system before the rock was added was

The density of solid aluminum is 2.70 g/cm3. If a 1g piece of aluminum is dropped in a cup of water, what will happen to the aluminum? (The density of water is 1.00 g/cm3.) It will sink to the bottom. It will float to the top. It will hover in the middle. It will move up and down.
Answer:
The correct answer is: It will sink to the bottom
Explanation:
Density is the mass of substance per volume. If we compare the density value of water (1.00 g/cm³) and aluminum (2.70 g/cm³), we can see that:
density aluminum > density water
(2.70 g/cm³) > (1.00 g/cm³)
Thus, when we put solid aluminum in a cup of water, the aluminum will have more weight than surrounding water, so it will drop to the bottom of the cup.
If a 1g piece of aluminum is dropped in a cup of water It will sink to the bottom. Therefore option A is correct.
When comparing the densities of two substances, the denser substance tends to sink while the less dense substance tends to float.
In this case, the density of aluminum (2.70 g/cm3) is greater than the density of water (1.00 g/cm3). Therefore, when the 1g piece of aluminum is dropped into the cup of water, it will be denser than the water and sink to the bottom of the cup.
Option B, C, and D are incorrect because they describe scenarios where the aluminum would need to be less dense than water in order to float or hover in the middle.
Therefore option (A) It will sink to the bottom is correct.

An alteration in the nucleotide sequence of a gene can alter the gene product. Each sentence is made up of three‑letter words, representing mRNA codons. THE FAT CAT SAT THE CAR WAS RED SHE HAS THE DOG The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or insertion mutation. Identify which sentence represents a substitution, which represents a deletion, and which represents an insertion.
Answer:
This question is incomplete as the sentences depicting mutated sequences are not included. The complete part is:
1) The cat was red 2) The fat aca tsa t 3) SHE Has The DG
The answers are:
1. The cat was red - Substitution
2. The fat aca tsa t - Insertion
3. SHE Has The DG - deletion
Explanation:
A mutation, as stated in this question, is an alteration in the nucleotide sequence of a gene, which can alter the gene product. In this question, each sentence is made up of three‑letter words, representing mRNA codons. The sentences are:
THE FAT CAT SAT
THE CAR WAS RED
SHE HAS THE DOG
1. A substitution mutation is that mutation involving the replacement of a nucleotide by another in a sequence. In the sentence; THE CAR WAS RED, R letter was replaced by letter T, hence, the sequence/sentence changed to THE CAT WAS RED.
2. An insertion mutation involves the addition of a nucleotide into the original sequence. In the sentence/sequence; THE FAT CAT SAT, letter A was added in between "fat" and "cat" to change the sentence to THE FAT ACA TSA T.
3. Deletion mutation involves the removal of a nucleotide from an original sequence. In the sentence/sequence; SHE HAS THE DOG, letter O was removed from the sentence to change it to SHE HAS THE DG.
