Answer:
A) The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.
B) The five major hormones are: gastrin ( stomach ), secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).
Explanation:
Explanation of answer A):
Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

what accounts for the different number of atp molecules that are formed through cellular respiration?
Because the composition of electron transport chain varies between species, various organisms use the electron transport chains to produce varying amounts of ATP.
What causes cells to produce the most ATP?The majority overall ATP synthesis takes place during cellular respiration inside the mitochondrial matrix, producing about 32 ATP molecules for every glucose molecule that is oxidized.
What causes about 90% of the ATP produced during cellular respiration?Nearly 90% of the ATP produced by cellular respiration is produced via oxidative phosphorylation.By substrate-level phosphorylation, less ATP is produced during glycolysis and the citric acid/Krebs Cycle.

A pig breeder wants to select for two traits: Weight and Feed intake. They have decided that they wish to increase weight whilst reducing feed intake. Both traits have the same heritability (0.3) and the same phenotypic standard deviation (2 units). The genetic correlation is 0.40 and the phenotypic correlation 0.30. The breeder has calculated the economic value on the two traits of +2 for weight and -0.5 for feed intake.
A selection index based on own performance is calculated and used to predict response to selection in one generation, which is 1.05 Kg for Weight and 0.25 Kg for Feed intake. The breeder has asked you a series of questions regarding the results.
A. What is a selection index used for in animal breeding?
B. What is the difference between economic values and predicted response? C. Are the economic weights appropriate for the breeder’s goal? Explain why the response for feed intake is positive.
D. Explain how an index could be designed such that there was no response for feed intake.
The selection index based on own performance is a useful tool for evaluating the potential response to selection for multiple traits.
A) A selection index is a technique used in animal breeding to identify the best breeding animals based on a selection of traits. This index is used to estimate the breeding value of an animal in a breeding program.
B) Economic values are used to assign relative economic importance to different traits in a breeding program. The predicted response, on the other hand, is the expected improvement in a trait due to selection for that trait. It is calculated by multiplying the selection differential by the heritability.
C) The economic weights are appropriate for the breeder’s goal since they reflect the breeder’s desire to increase weight while decreasing feed intake. A positive response for feed intake may be due to the genetic correlation between the two traits. Since the genetic correlation between weight and feed intake is positive, selection for weight will indirectly lead to an increase in feed intake.
D) To design an index such that there was no response for feed intake, the index would need to be designed so that it only selects animals based on their weight and not their feed intake. This would involve assigning a weight of zero to feed intake in the selection index. This would mean that only animals with the highest weight would be selected, regardless of their feed intake.
However, the economic weights used in the index should be appropriate for the breeder’s goal in order to maximize the desired response. In this case, the positive response for weight suggests that the economic weights used are appropriate, but the negative response for feed intake suggests that a different design may be necessary to achieve the breeder’s goal of increasing weight while reducing feed intake.

Modern whales lack hind limbs, and have tail flukes and ears specialized for hearing underwater. Which of the following is the correct order for the evolution of these whale characteristics?
A) Loss of hind limbs followed by tail flukes and underwater ears
B) Loss of hind limbs followed by underwater ears and tail flukes
C) Tail flukes followed by loss of hind limbs and underwater ears
D) Underwater ears followed by tail flukes and loss of hind limbs
Answer:
The correct answer is B) Loss of hind limbs followed by underwater ears and tail flukes.
Explanation:
Scientists estimate that the evolution of the Whale in the form which it now takes started approximately 50 Million years ago.
The most likely land animal to have taken the step to move back into the ocean is said to be the Bear. Even today, bears are known to be excellent swimmers and can swim and hunt in water and underneath it.
Other animals that have been suspected to have made this move, hence being the animal that evolved is the Hippopotamus.
Their transition is estimated to have taken only 10 million years. According to some scientists, this is the shortest time ever taken for any evolutionary transition to occur.
Why would a successful land animal transit into the sea? The answer is attributed to opportunity. Opportunity to feed even better and hence survive.
This is why the teeth is reported to have evolved first.
The next most immediate need for the transiting mammal was the ability to maneuver in its new environment - the waters. Hence the next evolutionary step was modified or specialized ears which helped them to hear properly and navigate underwater.
After this was the changes that occurred to their limbs.
nScientists refer to the Ambulocetus as the species that connects the dots on this one. It is said to have had specialized teeth for hunting, limbs that were already adapted for underwater swimming and hunting but whose tail was still intact as that of a land animal.

Answer:
Underwater ears followed by tail flukes and loss of hind limbs.

2. Which of these is not one of the water compartments in the body?
a- lymph
b- intercellular fluid
c- plasma
d- urinary bladder
1: Water 2: urinary bladder
1:Water is the solvent in which various solutes are dissolved in blood. Solutes such as salt, urea, and carbon dioxide are present in the blood in varying concentrations and play important roles in various bodily functions. Salt helps to maintain the body's electrolyte balance, while urea is a waste product that is filtered out by the kidneys. Carbon dioxide is a waste product produced by cellular respiration, and it is transported to the lungs to be exhaled.
2:The body is divided into various compartments that contain water, which is essential for various bodily functions. The intracellular fluid is the water present within the cells, while extracellular fluid is the water present outside the cells. Extracellular fluid can further be divided into interstitial fluid and plasma. Interstitial fluid is the water present in the spaces between the cells, while plasma is the liquid part of blood. Transcellular fluid refers to the various other fluid compartments in the body, such as cerebrospinal fluid, synovial fluid, and lymph. The urinary bladder is not considered a water compartment because it is a temporary storage organ for urine, which is a waste product that is excreted from the body.
Why did removing bees have a bigger effect than removing the rabbits?
I think removing bees have a bigger effect than removing rabbits because bees help a lot with our earth and some things would probably be bad without them. Bees do things like help plants grow, breed and produce food, and they transfer pollen between flowering plants so they can keep the cycle of life turning. Plus they make great honey ! But with the rabbits they can sometimes cause damage to the earth by overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields. and they also compete with native animals and domestic livestock for food and shelter, increasing grazing pressure and lowering the land's carrying capacity. So therefore, if we removed bees from our earth it would turn everything upside-down more then it would with rabbits. :)

Why is an herbivorous diet more energy efficient than a
carnivorous diet? Complete the statement about a rabbit and
a hawk to explain.
An herbivorous diet is more energy efficient than a carnivorous diet because plant material contains more easily accessible energy in the form of carbohydrates and less indigestible matter such as bones, fur, and other connective tissues.
Additionally, herbivores tend to eat more frequently throughout the day, which helps to maintain a steady supply of nutrients and energy.
For example, a rabbit eats mostly plants, which are high in carbohydrates and other nutrients and can graze on small amounts of food throughout the day. This allows the rabbit to extract as much energy as possible from its food and minimize waste.
On the other hand, a hawk, which is a carnivore, eats other animals that are often higher in protein but also contain a significant amount of indigestible material, such as bones and fur. Because of this, the hawk must expend more energy to hunt and consume its prey and may go for longer periods of time between meals.
Overall, an herbivorous diet is more energy efficient because it provides a steady supply of nutrients and energy with less waste and fewer energy expenditures required for hunting and consuming food.
