nt
Answer:
A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.
Explanation:
A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.
A cell may vary the rate of an enzyme controlled reaction by:
Degrading with timeAccording to the given question, we can see that we need to show how a cell can vary the rate of a reaction which is controlled by an enzyme.
As a result of this, we can see that there are different ways through which a cell may control the rate of reaction in an enzyme controlled state which are by the level of degradation with time.

What is G-zero (G0) and why is it important to the cell?
Answer:
The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase.

Cameron reads in his textbook that animal cells are composed of 90 percent water and 10
percent protein, carbohydrate, nucleic acid, lipid, and other molecules. He learns that
homeostasis is the process by which this composition is maintained. How does an organelle
in an animal cell control the content of water and other material in the cell?
F The cell wall splits apart to allow water and materials to enter the cell and waste
products to leave the cell.
G The cell membrane is selectively permeable, which controls the movement of materials
in and out of the cell by passive and active transport.
H Vacuoles in the cell open and draw in only the materials needed from outside the cell.
J
Lysosomes move out of the cell to capture and bring back needed materials.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.
Answer:
The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.
The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.
Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.
What will happen if ATP and NADPH are already used up at night?
Answer:
If ATP and NADPH are already used up at night , the production of glucose will stop.
Explanation:
IMPORTANCE OF ATP AND NADPH -: To temporarily store energy, the light-dependent reactions generate ATP and either NADPH or NADH. In light-independent reactions, these energy carriers are used to drive the energetically unfavorable mechanism of "fixing" organically inorganic CO2.
ATP is the molecular energy "currency" in biological systems. All energy produced by living organisms' cellular respiration must end up being used as ATP to power it. NADPH is a hydrogen carrier molecule reduced by NADP (Nicotinamide Adenine Dinucleotide Phosphate). While the light-dependent reactions take place, energized electrons hop on to electron carriers excited by photon energy from the sun (On Photosystem 2) and finally get to Photosystem one.
If ATP and NADPH are already used up at night, the fixation of carbon dioxide into glucose will halt. In other words, the light-independent reaction of photosynthesis will stop.
There are essentially 2 reactions in photosynthesis:
light-dependent reactionlight-independent reactionIn the light-dependent reaction, radiant energy is used to excite electrons chlorophyll molecules while electrons in water replace the excited electrons. ATP and NADPH are generated in the process.
The ATP and NADPH produced during the light-dependent reaction of photosynthesis are essential for the reduction of carbon dioxide into glucose in the light-independent reaction.
Hence, unless the light-dependent reaction takes place to make ATP and NADPH available, there is no other way to produce the precursors for the fixation of carbon dioxide into glucose.

When does facilitated diffusion occur?
Answer:
The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.
Explanation:
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins.
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
2. Which two biomes are known asthe dry biomes?
tundra and forest
desert and tundra
desert and grassland
Answer:
The desert and tundra biomes have very different temperatures as well as extremely different plants and animals. The desert can get very hot during the day, but cool off quickly at night. It has sandy soil and supports very little plant life. Animals found in the desert include lizards, javelinas, Gila monsters, coyotes, bobcats, scorpions, and kangaroo rats. The tundra is cold, dry, and often dark. The average temperature is about 10°F. The soil below the surface is permanently frozen, and is called permafrost. A few types of plants grow during the short summer season. Animals found in the tundra include caribou, foxes, wolves, and Arctic hares.

Select one or more:
a. Light
O b. Electrical
c. Thermal
O d. Mechanical
Answer:
A and C
Explanation:
The sun itself is light energy and the heat that you feel from the sun is thermal energy.
Light and Thermal energy is used when air is warming in the sunlight.
Energy is emitted by the sun some of which is radiated back and some enter the earth.Solar energy is created by nuclear fusion that takes place in the sun.What is energy?The capacity or power to do work, such as the capacity to move an object of a given mass by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. Energy is a conserved quantity.The law of conservation of energy states that energy can neither be created nor destroyed only converted from one form of energy to another.Hence, A and C option are correct.

Place the phases of a stem cell into the correct order.
A.differentiation, mitosis, specialization
B.gene expression, differentiation, mitosis
C.mitosis, gene expression, differentiation
D.mitosis, specialization, gene expression
Answer:
C. Mitosis, Gene expression, differentiation
Explanation:
Stem cells are referred to as undifferentiated cells which has the ability to develop into new specialized cells via cellular differentiation. The stem cell initially undergoes MITOTIC division to form new stem cells.
This stem cells then undergo GENE EXPRESSION by turning off some genes and turning on some in order to specialize the cell type. After this, the cell becomes DIFFERENTIATED i.e becomes another type of cell
Place the phases of a stem cell into the correct order.
The correct order would be mitosis, gene expression and then differentiation.
Stem cells can be defined as undifferentiated cells that possesses the ability to develop into many other different cells of the body. Before a stem cell becomes differentiated, the stem cell undergoes growth, mitosis and then information from the gene (DNA) in the cell will be needed to determine the type of cell it will become and be expressed before differentiating and becoming specialized to give rise to a particular type of cell.
