Describe the significance of enzymes in our digestive system having different optimal pH and optimal temperatures. (Hint: What does this allow our bodies to do?)
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.

What problems do animal cells have since they don't have cell walls?
Answer:
These antibiotics bond to protein molecules on the existing wall and prevent the cell from adding any new material as the wall stretches. When the cell wall stretches too far, it becomes weak and eventually bursts, destroying the cell. Since animal cells don't have cell walls, they are not affected by penicillin.

what can the enzyme sucrase break down?
Answer:
Sucrase is an enzyme that breaks sucrose down into glucose and fructose.
Explanation:
The bonds between the glucose and fructose molecules making up the disaccharide sucrose break due to the enzyme sucrase, and water is added as
H
and
OH
to the two molecules. This is called a hydrolysis reaction.
Hydrolysis is a chemical reaction in which water (hydro) breaks (lysis) a chemical bond in a dimer (two molecules bonded) and polymer (many molecules bonded) by adding
H
to one molecule and
OH
to the other molecule.
the __________ vertebrae articulate with the corresponding ribs.
Answer:
Each vertebra contains three points of articulation with ribs. The superior demifacet of a thoracic vertebra articulates with the corresponding rib (costovertebral joint). This rib articulates again with the costal facet on the transverse process (costotransverse joint). The inferior demifacet articulates with the rib below.

Which characteristic best supports that an offspring is produced by sexual reproduction and not asexual reproduction?
Answer:
The offspring has the same number of chromosomes as its mother and father.
Explanation:
The child shares the same number of chromosomes with both parents. Two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
What is sexual reproduction?A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization.
Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent. Asexual reproduction allows for the rapid production of vast numbers of children by a single person.
This is due to the fact that in asexual reproduction, the only single parent produces an additional child that is genetically identical to the parent.
Therefore, the sexual mode of reproduction is seen to be superior to the asexual mode.

which description of skeletal cartilage is incorrect?
The incorrect description is that Costal cartilages reinforce airways and support the external nose
The options were omitted but the complete question is :
Which description of skeletal cartilage is incorrect
Fibrocartilages are able to withstand both pressure and stretch.
Costal cartilages reinforce airways and support the external nose.
Elastic cartilages are able to tolerate repeated bending.
Articular cartilages cover the ends of most bones at moveable joints.
Costal cartilages are said to be at the anterior extreme of a rib cage. Their function is to give the ribcage a flexible structure and connect the ends of the ribs to the sternum. Respiratory cartilages are present in the Trachea and are responsible for flexible inhalation and exhalation thereby reinforcing airways and providing support to the structure of the nose.

O fecal regulation
O water regulation
oxygen regulation

Explanation:
To be precise, homeostasis is a process/phenomenon not a system. Homeostasis is actually the process of maintaining a stable internal environment despite changes in the external environment. There are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis.
Which of the following is false of the integumentary system?
A. The inner layer of the epidermis divides quickly
B. The body produces more melanin with stronger sunlight exposure
C. Too much UV radiation can mutate DNA in skin cells and cause cancer
D. Keratin is the pigment responsible for skin color
Answer:
Hey there the answer would be D. Keratin is the pigment responsable for skin color.
Explanation:
A. The top layer of the epidermus is made of dead skin cells. The inner player has to be constatnly making more cells
B.The body procudes more melanin with stronger sunlight exposure. This results because the UV of the sun causes T-T dimers which is a type of DNA damage.
C. UV causes genetic mutation which can result in cancer if not fixed by the cell
D.Keratin is found in the epidermis and with thick layer of skin found in the hands and feet. Melainin is responsible for skin color.

Louisiana is losing about 16 square miles/year as a result of coastal erosion. This estimation is a variable as the rate of coastal erosion varies from time to time.
Coastal erosion is the process through which local sea-level rise as a result of intense wave action in coastal sea levels which deteriorate over time along the shore.
In Louisiana, coastal erosion results in the depletion of wetlands via the routes of coastal lines in swamps and marshes. Storms and other natural occurrences that induce erosion impact all coasts. The combination of storm surge at high tidal waves with additional effects from large waves, as well as circumstances often associated with landfalling tropical severe storms, provides the most devastating conditions in landfilled regions.
Therefore, the amount of landmass lost by Louisiana is estimated to be 16 square miles/year as a result of coastal erosion.
