Answer:
1,100 to 1,200 genes
Explanation:
these are instructions for proteins which help around the body
The number of genes on chromosome 17 is estimated to be around 1,200 to 1,500.
What are genes?A gene is the most basic physical and functional unit of inheritance. They carry information that determines your traits. They are present on specific location of chromosomes.
Chromosome 17 is one of the 23 pairs of chromosomes in humans and is approximately 81 million base pairs long. The number of genes on chromosome 17 is estimated to be around 1,200 to 1,500. However, the exact number of genes on chromosome 17 is not yet known, as gene prediction algorithms have limitations and some genes are yet to be discovered or accurately annotated.
Additionally, some sections of the chromosome may not contain protein-coding genes but may still play important regulatory roles in gene expression.

d. To copy original DNA strands into complimentary strands
Answer:
D
Explanation:
To copy original DNA strands into complementary strands
The option (D) is correct. To copy original DNA strands into complimentary strands.
What are complementary strands of DNA?Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
Moreover, the complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions. First write the correct base pairing below the original sequence and label the 5' and 3' ends.
Therefore, the upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

B. Interchange the labels inside ovals A and
C. Interchange the labels on the arrows 5 and 1.
D. Interchange the labels on the arrows 2 and 4.
According to the diagram of the rock cycle, the flaw can be corrected by interchanging the labels inside ovals A and B. The correct option is A.
What do you mean by the rock cycle?The processes which involves the production and alteration of the different types of rocks that are found in the Earth's crust that make up the rock cycle.
The three main forms of rock include igneous, metamorphic, and sedimentary rocks. These are formed and decomposed according to various applications of heat and pressure on them throughout the time, and this process-based network is known as the rock cycle.
The reason the diagram for the many types of rocks and how they change is shaped into a circle gives rise to the name rock cycle. It resembles the rocks that goes through a cycle in certain ways. According to their location and circumstances, it appears that the rocks are recycled continuously and are transformed into various forms of rocks.
Therefore, according to the diagram of the rock cycle, the flaw can be corrected by interchanging the labels which are inside ovals A and B.

What is the difference between the origin and insertion of a muscle?
Answer:
A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.
The terms "origin" and "insertion" in relation to muscles describe the two places where a muscle attaches to bones or other body parts.
The place of solid or fixed attachment of a muscle is known as its origin. This is the starting point of the muscle, where it contracts very rapidly. Typically, the origin is the bone that is more stable or located closer to the center of the body.
The dynamic attachment point of a muscle is called an insertion. This is where the muscle ends and attaches to a bone that moves in response to muscle contraction. In most cases, the insertion is located away from the center of the body or the more mobile bone.

What is a function?A function is a relation between two sets of values, an input and an output value given as X and Y respectively, in which each input value of X has exactly one output value for Y.
An example of a function is y = x^2 + 1.
If x = 1
Then;
y = 1^2 + 1
y = 2
The input of a function is called the domain.
The output of a function is called the range.

What describes the roles of carbon dioxide and water in these two processes?
a. Carbon dioxide and water are the reactants of both processes.
b. Carbon dioxide and water are the products of both processes.
c. Carbon dioxide is a reactant of photosynthesis; water is a reactant of cellular
respiration.
d. Carbon dioxide and water are the reactants of photosynthesis and the
products of cellular respiration.
Answer:
A is the answer
Explanation:
Carbon dioxide and water are the reactants of both processes
The statement that best describes the roles of carbon dioxide and water in these two processes is as follows:
Carbon dioxide and water are the reactants of photosynthesis and the products of cellular respiration.Thus, the correct option for this question is D.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.
The complete reaction of cellular respiration is as follows:
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).Therefore, the correct option for this question is D.

A man suffers a penetrating wound through the anterior axillary fold, with resulting damage to one of the main terminal branches of the brachial plexus. Among the effects is a significant weakening of flexion of the elbow. One or more other effects to be expected is (are):______.
A. Loss of cutaneous sensation on the tips of several fingers.
B. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
C. Only weakening of flexion at the shoulder.
D. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the arm.
Answer:
The correct answer is option b. Weakening of flexion at the shoulder and loss of cutaneous sensation on the anterolateral surface of the forearm.
Explanation:
Brachii and brachialis are the two muscles that are innervated by the Musculocutaneous nerve. These muscles help in the production of the flexion at the elbow, and it is known that the musculocutaneous nerve is damaged due to the penetration through the anterior axillary fold.
Other than these muscles there would be an effect on the nerve that provides sensory signals or information to the anterolateral surface of the forearm, known as the lateral antebrachial cutaneous nerve.
Thus, the correct answer is: option B.
