Answer:
Tubercle: allows tendons to attach to bone
Foramen: Allows blood vessels and nerves to travel through bone.
Fossa: Allows to bones to form a joint.
Explanation:
The tubercle or tuberosity in the human seletal system, is a protrusion that allows for attachment of skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.
Answer:
1. an eclipse of the Sun
2. state (phase) of matter
3. 5.0 g/cm3
Explanation:
1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.
2. Considering the following groups: Group A: water, aluminum, water vapor
Group B: gasoline, ice, air
Group C: alcohol, iron, oxygen
One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.
This shows that the STATE (PHASE) OF MATTER was the basis of classification.
3.
Answer:
The correct answer would be C. The protein synthesized will contain many erroneous amino acids since the loss of one base will shift the reading of the encoded base sequence.
Deletion mutation that does not occur in the multiple of three bases can results in frame-shift mutation.
It changes the reading frame of nucleotide in DNA. Thus, the reading frame of codons in mRNA would also change.
Consequently, the sequence of amino acids in a polypeptide chain would change or alter. Thus, a protein would contain many erroneous amino acids.
An example of the same is shown below in the image.
