Answer:
All of the above
Explanation:
Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:
- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.
- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.

Explanation:
what is a difference between a lens and a mirror
Answer:
hi
Explanation:
The lens is a material made of glass or plastic bounded by two surfaces. ... A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.
have a nice day
Answer:
The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.
state how facilitated diffusion is achieved describe ways
Answer:
The polar membranes/ions go through the protein to bypass the hydrophobic tails, which are "afraid" of charged molecules.
Glucose passes through the protein because it's too big to diffuse on its own.
I hope this information was very helpful.
How are stars described, using their physical properties
and distance
Answer: Two characteristics define brightness: luminosity and magnitude. ... The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth. brainliest?
Explanation:
Why does a larger quantity of water take longer to freeze ?
Answer:
If the water is initially hot, cooled water at the bottom is denser than the hot water at the top, so no convection will occur and the bottom part will start freezing while the top is still warm. This effect, combined with the evaporation effect, may make hot water freeze faster than cold water in some cases.
Explanation:
Answer:
As the quantity of liquid is bigger it will take longer to freeze because more energy will have to be used. There is a state of matter that water has which is called super cooling this is where the water is at a freezing tempture but ice crystals haven't be formed correctly. Different liquids freeze at different temperatures. Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Thicker liquids will freeze more slowly and some will not freeze at all.

why do you produce carbon dioxide when working out?
Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

Sami had low birth welght as a lamb but quickly grew into a large sheep.
Answer:
D. Sami had low birth weight as a lamb but quickly grew into a large sheep.
Explanation:
The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.

D upland sandpipers are primary and secondary consumers because they eat grasses and grasshoppers.
Answer:
D.
Explanation:
They consume both things that consume food and things that produce food.
Owls and hawks are both predators, but hawks hunt during the day and owls hunt at night. This reduces ____________________.
A. predation
B. adaptation
C. mutualism
D. competition
Answer: D. competition
Predators compete with each other in order to achieve prey for food. Since owl hunt at night and hawks hunt in the morning, there is a way unlikely chance they would encounter one another to fight for food.

Metabolic acidosis can occur as a side effect of taking acetazolamide because: Select one: a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. b. chloride ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. c. bicarbonate ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions. d. chloride ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions.
Answer:
a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.
Explanation:
Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.
identify the type of blood vessels that artherosclerosis will affect. Why is it important that these blood vessels be elastic and flexible?
Answer:
Atherosclerosis affects arteries, these blood vessels are elastic and flexible in order to allow good blood circulation
Explanation:
The blood vessels are classified into three types: arteries, veins, and capillaries. An artery is a muscular blood vessel that is able to carry blood away from the heart to different parts of the body. Healthy arteries need to be elastic and flexible in order to adjust their diameter and thus control blood flow by maintaining blood pressure. Arteriosclerosis is a chronic disease caused by the accumulation of fatty substances (especially cholesterol) in the artery walls, thereby difficulting blood circulation by thickening and hardening these walls.

Colorblindness is an X-linked recessive disorder. If Abby has normal vision (but her father was colorblind) and Ryan is not colorblind. What are the chances that their daughter is colorblind? SHOW ALL WORK FOR CREDIT. (To insert a table in your answer if necessary click on the three dots, click on the icon that looks like a table and you can customize the number and type of boxes you need)
Answer:
Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.
Since Abby's father was colour blind, Abby must be a carrier for the same.
Which means Abby's genotype would be ‘XXᶜ’.
Now, Ryan is not colourblind which means his genotype would be ‘XY’.
Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.
Which means she wouldn't be colourblind but she might be a carrier of the disorder.
XXᶜ × XY
⬇️ ⬇️
X, Xᶜ X
↘️ ↙️
XX , XXᶜ
Their daughter will have either XX genotype or XXᶜ genotype.
And her chances of being colourblind thus, becomes zero.
Regions with otters tend to host dense forests of kelp, a brown seaweed that anchors to the seafloor. Kelp forests provide a physical structure in which diverse marine communities find shelter and food. Sea otters prey on urchins, which consume kelp. According to James Estes, sea otter populations have dropped dramatically in Alaska and the Aleutian Islands. If sea otter populations in these areas continue to decline, what might happen with populations of sea urchins and kelp
Answer: the urchin population will grow very large and the kelp will diminish

Has the change in the environment (in this case the food preference of predators) caused natural selection to start occurring in this fish population?
Answer:
Yes.
Explanation:
Yes, change in the environment conditions leads to the initiation of natural selection in this fish population if the food preference of the predators changes because changes in the food preference of predator causes lowering of population which can't be eaten by the predator earlier. Changing rainfall and drought patterns reshaping the population and existence of fish by availability of type of food to predators which ultimately leads to natural selection among population of fish.

Explanation:
1. A person becomes diabetic when they can't make insulin, or when their cells stop
responding to insulin. What happens to a person when they eat food and are diabetic?
How is the homeostasis disrupted?
Answer:
Most foods especially carbohydrate diets ends up in the blood stream in the form of sugar causing a spike
Explanation:
The high sugar level in the blood then penetrate the body cells in an uncontrolled manner since there is no enough or no insulin produced to regulate it.
