Answer:
A. fitness
Explanation:
Fitness, also known as 'evolutionary fitness', refers to the ability of one species/population/individual to survive and reproduce in its environment. Fitness is a fundamental concept in the evolutionary theory proposed by Darwin, because this concept highlights the importance of natural selection as the key mechanism by which evolution occurs. Fitness can be measured as the success of passing genes associated with specific phenotypic traits to the next generation.
Why couldn't yeast use both sugar and artificial sweetener for cell respiration?
Yeast couldn't use both sugar and artificial sweetener for cell respiration because of the low calorie content of artificial sweetener.
What is artificial sweetener?Chemicals called artificial sweetening agents are used to sweeten food. They do not, however, provide our bodies with extra calories.Which one will have better yield?The sugars will have better yield because natural sugars like sucrose have more calories than artificial sugars.This increased energy will allow the yeast to metabolize faster and hence more carbon-dioxide is released.What is cellular respiration?"Cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a compound called as adenosine triphosphate (ATP)."

What are the weaknesses or inaccuracies in the
model the student created?
Answer:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

The reaction would continue to proceed through the path of Y.
The reaction originally proceeded through the path of X, but now proceeds through the path
of Y
The reaction would continue to proceed through the path of x
Answer: The reaction originally proceeded through the path of y but now proceeds through the path of X is the answer
Explanation:
Since the enzyme works based on a lock and key model, the reaction will continue through path X (the path of the uncatalyzed reaction).
An enzyme is a biological catalysts that promotes many biochemical reactions in the body. Enzymes are specific. Only a given enzyme can catalyze a particular reaction.
Owing to the fact that enzymes function based on a lock and key model, When active site of an enzyme is damaged, it can no longer fit into its substrate hence, the reaction will continue through path X.

A couple receives DNA analysis, which determines that they are both heterozygous for the gene responsible for Tay-Sachs disease. Should doctors or the government have a role in deciding if the couple can have children together? Construct an argument to explain why or why not.
Answer:
The correct answer should be - no doctors or government can not decide if they can have children together or not, it is their personal decision and one can explain complications and consequences only.
Explanation:
Tay-Sachs disease is autosomal recessive disorder it means for the affecting an individual it requires both copy of the affected allele and in heterozygous condition individual act as a carrier and pass the affected gene to next generation. In this case, both parents are heterozygous which means there are 25% chances to have an affected child.
A genetic counselor or doctor can explain the problems parents can have with the affected child and what are the chances of the affected child, however, they can not and should not decide if they both should have children together or not as it is their personal choice and they should be responsible for pro and cons.

A 50-year-old man became lethargic and drowsy with flushed dry skin after eating a large meal. His family became concerned when he was difficult to rouse, and he had a fruity odor to his breath. He was transported to an emergency facility, where he gave a history of extreme thirst, hunger, and frequent urination. He recently had an upper-respiratory infection that was slow to clear. Adult-onset diabetes mellitus is suspected.
Required:
Which blood test would be ordered?
Answer:
A fasting blood sugar test will be ordered.
Explanation:
A fasting blood sugar test or a glycated hemoglobin test is ordered in such situations. Additionally, tests to determine the insulin level as well as an ophthalmic investigation to determine diabetic retinopathy are ordered. Blood sugar level less than 100 mg/dl is classified as normal. A person is pre-disposed to diabetes if his blood sugar level is between 100-125 mg/dl.
A confirmed case of diabetes mellitus will have a fasting blood sugar level, 126 mg/dl and higher. Insulin administration and a proper management of diet are essential in managing the condition.
what is hormone injection and subcutaneous implants??
Explanation:
The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.

Answer:
TRUE
Explanation:
Your friend runs out of gas and you have to help push his car. Discuss the sequence of bones and joints that convey the forces passing from your hand, through your upper limb and your pectoral girdle, and to your axial skeleton.?
Answer: The sequence of bones and joints that convey the forces include: From metacarpal bones --> carpal bones --> midcarpal and radiocarpal joints --> radius and ulna bones --> elbow joint --> humerus --> glenohumeral joint --> scapula --> acromioclavicular joint --> clavicle --> sternoclavicular joint --> sternum.
Note: the sign (-->) represents "into the".
Explanation:
The skeletal system is made up of bones of the skeleton, their joints and the skeletal muscles which acts together to bring about different movements in the body. The skeleton of a vertebrate had the following basic plan:
--> The axial skeleton: this forms the main central axis. This is made up of the skull,vertebral column, breastbone (sternum), and ribs.
--> The appendicular skeleton: this consists of parts that articulates with the axial skeleton. This is made up of the forelimbs, hindlimbs, pelvic and pectoral girdles.
From the question given, in an attempt to help push the friend's car, the sequence of bones and joints that convey the forces will pass from METACARPAL BONES of your hand into the CARPAL BONES at the base of your hand. Forces will then pass through the MIDCARPAL and RADIOCARPAL JOINTS into the RADIUS and ULNA bones of the forearm. These will pass the force through the ELBOW JOINT into the HUMERUS of the arm, and then through the GLENOHUMERAL JOINT into the SCAPULA. The force will travel through the ACROMIOCLAVICULAR JOINT into the CLAVICLE, and then through the STERNOCLAVICULAR joint into the STERNUM, which is part of the axial skeleton.
As one pushes against the car, the forces will pass in a sequential manner from the bones of the hand to the bones that are part of the axial skeleton.
• Forces will pass from the metacarpal bones of the hand into the carpal bones at the base of the hand, when one pushes against the car.
• After that the forces will then mediate via the radiocarpal and midcarpal joints into the ulna and the radius bones of the forearm.
• Then the force will move via the arm's humerus, and then via the glenohumeral joint into the scapula.
• The force then will mediate via the acromioclavicular joint into the clavicle, and then via the sternoclavicular joint into the sternum, that is, the part of the axial skeleton.
Thus, in the given case, force gets mediated through the bones of the hand and towards the bones of the axial skeleton in a sequential manner.
