EXPERIMENT 2: Suppose starch would eventually be converted to simple sugars in the absence of amylase. Approximately how long would your experiment have taken if you did not use amylase

Answers

Answer 1

Answer: 5years

Explanation: Breaking down of starch into simple sugar without the deployment of amylase to act on it will take a long period of time (as long as 5years).

Enzyme Amylase saves us a lot of time in converting starch into simple sugars. Instead of taking up to years, Amylase only requires about 10minutes to get the job done. It does this by hydrolyzing starch into maltose, glucose, shorter polysaccharides, and dextrins.

A 56-year-old man with an insufficient aortic valve is scheduled for surgery. Identify the chamber of the heart that the regurgitated blood most likely enter. Will the blood regurgitated primarily during systole or diastole?

Answers

Answerand Explanation:

The regurgitated blood will enter the left chamber of the heart. This is because as the patient's aotic valve is not working properly, it does not close properly, which allows a backflow of blood to occur towards the left chamber of the heart, as this chamber relaxes to be filled with blood pumped by the right camera.

As the regurgitated blood is a pumped blood, we can consider that it will happen, mainly during systole, which is the moment when the heart contracts to pump blood. This contraction will be made with the malfunction of the aortic valve which will cause blood regurgitation.

Answers

About the question:

You will find the chart in the attached files

Answer:

b) x: fin

   y: lateral line

   z: swim bladder  

Explanation:

The dorsal fin is found in the dorsal region of the fish body. Depending on the species, there can be one or two dorsal fins. Membranous structures and bony or cartilaginous ratios compose the fins. One of the main functions is to stabilize the body in water, providing equilibrium. When the dorsal fin is erect, it acts as a keel, helping the fish not to turn aside. Fishes also use these fins as protection because the cartilaginous or bony ratios act as spines. The animal uses these spines to defend itself from predators. The morphological variety of dorsal fins in the different species is used in taxonomy.

The Lateral Line is a system or sensory organ composed of special receptors called neuromasts, which can be found all along the lateral region of the animal. The lateral line perceives information from the environment, such as light, sound, or water movement, among others. These signs are translated into nervous messages. The lateral line is useful to detect prey, predators, other animals moving, objects, etcetera. It is significant for intraspecific interaction, especially during swimming motions in schools. The lateral line receives perturbations of short distance, generated by other living beings or by objects. Some studies confirm that the lateral line is also sensitive to chemical stimuli.

The swim bladder is a neumatic sac-like structure filled with gases coming from the blood. Its main function is to allow neutral floating and let the animal in suspension at any depth, with no need for muscular effort. The animal can regulate the size of the bladder. This organ can be found in most pelagic fishes, while the benthonic ones or the ones that actively swim lack it.

Answers

Answer:

a. Calcitonin

b. Calcitonin

c. PTH

d. PTH

e. PTH

f. PTH

g. Calcitonin

Explanation:

Calcitonin is a short peptidic hormone secreted by the parafollicular cells of the thyroid gland. Conversely to the parathyroid hormone (PTH), calcitonin reduces the calcium level in the blood. If the calcium concentration in blood decreases, the concentration of calcitonin secreted decreases too. On the other hand, the PTH peptide hormone is an important hormone secreted by the parathyroid glands that affect bones and tissues. PTH stimulates the proliferation and activity of the osteoclast (specialized cells that play a crucial role in bone resorption) in order to increase calcium levels in the blood. PTH stimulates the expression of the receptor activator of nuclear factor-kappa-Β ligand (RANKL) protein, thereby activating osteoclast differentiation and inhibiting osteoclast apoptosis.

Reproduction is important for every type of living thing. Without it, species would die out. To ensure their survival, animals have developed unique adaptations to improve their chances of reproducing. Behavioral adaptations are behaviors an organism performs to help it survive. Structural adaptations are physical features that help an organism survive.

The image below shows two peacocks. The male peacock is large and brightly colored. The female peacock is not as colorful. The size and color of the male's feathers attract females. This is an example of a structural adaptation intended to help with reproduction. Another structural adaptation is when male deer grow large antlers to attract females. Animals also use behavioral adaptations to attract mates. For example, male frogs sing to attract females and male spiders dance to attract females.



Plants also have adaptations to help with reproduction. While animals use behavioral and structural adaptations to improve reproduction, plants only use structural adaptations. For example, brightly colored flowers attract butterflies. Certain flowers also have nectar or give off an odor to attract insects. Attracting butterflies and other insects is important because they play a role in reproduction by pollination.

Which of the following describes an adaptation that relates to reproduction?

A. Hawks have sharp beak to help them quickly catch their prey
B. Elks attach leaves and grasses to their antlers to help them appear larger
C. Polar bears have white fur to help them blend into their surrounding environment
D. Whales have a thick layer of fat called blubber

Answers

Answer:

B. Elks attach leaves and grasses to their antlers to help them appear larger

Explanation:

The above option is the correct answer.

As elks appear larger, it tend to make other male elks to be scared to fight that particular elk for a female elk. Also, the female elk becomes more attracted to larger male elk.

Male elk are known to actually retain their antlers for more than half the year. Such elks do not likely group themselves with other males when they have antlers.

mphibians have only one lung to breathe in air
nly a small amount of air enters the lungs as they breathe.
surface area of the lungs are small compared to other terrestrial vertebrat
surface area of the lungs do not have folds compared to other terrestrial v​

Answers

Answer:

These lungs are primitive and are not as evolved as mammalian lungs. Adult amphibians are lacking or have a reduced diaphragm, so breathing through the lungs is forced. The other means of breathing for amphibians is diffusion across the skin. To aid this diffusion, amphibian skin must remain moist.

Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.

Explanation:

Amphibians utilize gills for breathing early in life, and develop primitive lungs in their adult life; additionally, they are able to breathe through their skin.

How does an ATP molecule release
energy for cells?
A. changing the base, adenosine, to guanine
B. breaking the bond between the 2nd and 3rd
phosphate
C. removing the ribose sugar

Answers

Answer:

The correct answer is - B. breaking the bond between the 2nd and 3rd.

Explanation:

ATP molecule is known as cellular currency as it provides energy for cellular functions. ATP released energy when one phosphate group is removed or eliminated by breaking a phosphoanhydride bond. The rebreaking of this bond and removal is known as hydrolysis, and ATP is converted to adenosine diphosphate (ADP).

Breaking the bond between the 2nd and 3rd phosphate groups provides a very high amount of energy. There is also additional energy released when phosphate is removed from ADP to form adenosine monophosphate (AMP).
