How would I explain it?
Answer:
What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.
Explanation:
A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.
The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.
Compare and contrast photosynthesis and cellular respiration. Why are the processes like two sides of the same coin?`
Answer:
In photosynthesis reserve food material (starch) is prepared using CO2 and H2O .
In cellular respiration reserve food material is broken down into CO2 and produce energy.

A geologist is studying a mountain. It is made up of many relatively even
layers of igneous rock. What can the geologist conclude about how the
mountain formed?
A. It formed when an earthquake caused faults to form in a body of
rock.
B. It formed when a glacier melted and deposited rock and sediment.
C. It was formed by many layers of sediment piling up.
D. It was formed by a series of volcanic eruptions.
The mountain was formed by a series of volcanic eruptions. Option D
What can be concluded?The geologist can infer from the data that the mountain was created by a sequence of volcanic explosions. It is stated that the mountain is composed of numerous, generally uniform strata of igneous rock.
In most cases, molten material such as lava or magma that is ejected during volcanic eruptions solidifies to produce igneous rock.
Multiple igneous rock strata may accumulate over time while the volcanic activity persists, eventually producing a mountain.

How does the prophase step play a role in plant growth?
Answer:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation

Which type of rock has a coarse texture due to slow cooling in magma chambers?
A.extrusive
B.intrusive
C.metamorphic
D.sedimentary
Answer: Intrusive
Explanation:
If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture.
Hope this helps!! :D
Answer:
intrusive
Explanation:
Intrusive igneous rocks form at some depth within the crust due to slow cooling of magma, resulting in formation of large crystals. Individual crystals can be seen with the naked eye. These rocks are termed texturally as coarsely crystalline or phaneritic.
A multicellular organism begins life as a single cell-a fertilized egg with a
complete set of chromosomes. The picture in Figure 10-2 above shows how the
cell divides to become two cells, then four cells, eight cells, and so on. Which of
the following statements best describes what happens during this process?
Answer options:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
b.) chromosomes are divided evenly during cell division so that each new daughter cell has an equal share of the original set.
c.) chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.
d.) chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.
Answer:
a.) chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
Explanation:
The cell divisions that allow organisms to grow are called mitosis. Before mitosis, all the DNA is duplicated.
Then, during mitosis, it condenses to form chromosomes. The identical chromosomes align in the centre of the cell. Then, they are equally distributed to among two daughter cells.
These two daughter cells each have a complete set of chromosomes. Each daughter cell identical to the parent cell and to the other daughter cell.
Which of the following is not a natural cause of extinction?
a.competition due to overpopulation
b.introduction of non-native species
c.catastrophic events
d.disease
Answer:
Introduction of Non-native species would be the answer. ( B )
Explanation:
Now let's break it down.
A. Competition due to overpopulation
Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.
B. Introduction of Non- native species.
So what does it mean by Non-native species?
It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.
C. Catastrophic Events
Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.
D. Disease
This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.
So, the Answer would be B.
HOPE THIS ANSWER HELPED :)Among the given options, the one that is a natural cause of extinction would be:
b). Introduction of non-native species.
'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.
These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.
Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.
They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.
Hence, option b is the correct answer.

How do calcium ions help amplify the signal?
HELP PLEASE!!!
Answer:
Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.

what are the different ways of storing tools and equipment safe
answer is included in the picture below.
Answer:
Step 1
Delegate a portion of your garage, shed or basement closet as a place to store tools. Clean out the junk and clutter and make a space only for tools. Figure out how much space is needed for the amount of tools you have. Sweep away cobwebs, dirt and other foreign matter. Get a shelving unit and store chemicals, liquids and paint substances out of the reach of children and pets.
Step 2
Find the parts. Locate cords, bits, nails and screws and organize them. Allocate plastic bins to store smaller household tools. If you have a large tool collection, organize by type for easy location. Keep the parts for each specific tool close by.
Step 3
Clean out dirt and debris from tools. Oil power tools to lubricate moving parts. Repair loose handles and clean out oil or other fluids used to power the tool. Sharpen blades and replace worn out parts.
Step 4
Set up racks. Mount commercially available racks along the wall of your garage or storage area to hang garden tools, cords and other equipment. Screw racks into the wall with screws recommended by the manufacturer and a power drill. Wind long cords in a loop and hang from rack. Place tools on racks by the handle. Draw the outline of the tool with a permanent marker to identify its place, or use labels to mark the location.
Step 5
Create a library. For tools and appliances that have various functions, designate a library area or bin within the storage space for user manuals and warranty sheets. Store the booklets alphabetically and in a dry area. Type up a sheet listing all of the books to create simple table of contents.

Give the function of all of the following parts of a typical flower. a. Petals
b. Stamen c. Pistil
d. Ovule
A.Petals. Usually, petals are the most prominent part of a flower structure, owing to their vivid color (in most flower examples) and sometimes scent. Their main function is to attract pollinators and also protect the inner reproductive structures of a flower. In some flowers, petals are absent or reduced.
B.Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
C.Pistil interaction precedes fertilization in the flower. Important changes occur in the pistil, which play a role supporting, but also controlling pollen-tube growth
D. The ovule is the organ that forms the seeds of flowering plants. It is borne in the ovary of the flower and consists of nucellus protected by integuments, precursors of embryo/endosperm, and seed coat, respectively.

What two groups are represented in archaeopteryx?
Please help
Answer:
The species of Archaeopteryx is lithographica and siemensii
Explanation:
Fun fact: Archaeopteryx is a combination of two ancient Greek words: archaīos, meaning "ancient," and ptéryx, meaning "feather" or "wing."
Archaeopteryx has long been thought to be the earliest known bird and a transitional form between birds and reptiles.
What are Archaeopteryx?Many consider Archaeopteryx, which lived approximately 150 million years ago, to be the first bird.
It is actually a transitional species between the birds we see in our backyards and predatory dinosaurs like Deinonychus.
Many features of Archaeopteryx, such as teeth and a long tail, indicate that it evolved from comparatively tiny carnivorous dinosaurs.
It also has a wishbone, a breastbone, hollow thin-walled bones, air sacs in the backbones, and feathers, as do nonavian coelurosaurian relatives of birds.
Archaeopteryx was thought to be the first recognized bird and a transitional form between birds and reptiles for a long time.
Thus, the two groups that are represented in archaeopteryx are birds and reptiles.

There are four kinds of tissues in the human body. They are muscle, nervous, connective, and epithelial tissues. Which of the following is true about all of these tissues?
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
