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)."

How would this change to the enzyme's function be best described using the graph above?
Choose 1 answer.
The reaction originally proceeded through the path of Y, but now proceeds through the path of
Х.
B
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.

The lynx and the wolf are the only secondary consumers on the list.
Explanation:
In the trophic web, the energy transference occurs when each organism feeds on the preceding link and is eaten by the following link.
The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.
The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.
On the other hand, the moose and the elk, are both first consumers.

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.

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:
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.
