Chemical reactions that absorbs more energy than they release are considered to be endothermic.
What is endothermic reactions?Endothermic reactions involve the absorption of heat from the surroundings, resulting in a decrease in temperature of the surroundings. In these reactions, the reactants have lower energy than the products, and the difference in energy is absorbed as heat from the surroundings. Examples of endothermic reactions include the melting of ice, the evaporation of water, and the reaction of baking soda and vinegar.
In contrast, exothermic reactions release more energy than they absorb, resulting in an increase in temperature of the surroundings. Examples of exothermic reactions include combustion reactions and the reaction between acid and base to produce salt and water.

Two characteristics of most plants are a root system and a shoot system. Most of the structures in these systems are common to all plants; however, there are some variations. Which structure can sometimes be found as part of the shoot system? Stems leaves roots flowers
Answer:
stems, leaves, flowers
Explanation:
There are two parts in the plants ----
1. the shoot system
2. the root system
Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.
The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.
4. Choose the microscopy technique that would best fit the needs of each scenario.
Scenario 1: Scientists are attempting to identify the specific type of leukemia a person has based on cell surface structures. ___
Scenario 2: Researchers are studying chemotaxis in white blood cells. Chemotaxis is the movement of living cells in response to a particular substance. ___
Scenario 3: Cell biologists are interested in measuring the distance between the inner and outer nuclear membranes, and need an instrument capable of producing images where the tiny distance between these two membranes is clear. __
Answer: Scenario 1: SEM
Scenario 2: Light
Scenario 3: TEM
Explanation:
The technique applied to observe and analyze objects that cannot be seen with the bared eye is called the microscopic technique.
1. The technique used will be SEM. A scanning electron microscope (SEM) is used to generate an image on the individual surface with the help of electron lasers.
It is useful in apprehending cell surface fabrication and topography.Therefore, to study the cell surface structure of leukaemia SEM is best.2. The light microscopy technique can be applied to study chemotaxis.
When there will be a movement in the living cell due to response towards chemical then the light microscope can be used to visualise the cells.Therefore to study chemotaxis light microscopy should be employed.3. The transmission electron microscope (TEM) method can be used to know the gap between the inner and outer layers. They are used for observing very thin segments of specimens.
Through the thin fragments, the electron flows easily and the image is produced.Therefore, TEM should be used by scientists to measure the distances.To learn more about the microscopy techniques follow the link:

Explanation:
As you walk to physics class, you start out at a speed of 2 m/s, for a time of 120 seconds (you’re really excited to get to class). Then you see your friend and slow down to a speed of 0.5m/s for 30 seconds. You stop at your locker for 40 seconds (a speed of 0 m/s). You realize that you are about to be late so you hurry to class at a speed of 1 m/s and get to class just as the bell rings (4 minutes after your trip started). How far did you travel total?
Answer:
The total travelled distance is [tex]51065 \mathrm{~m}[/tex]
Explanation:
• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.
• Calculate total speed;
[tex]\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}[/tex]
• Calculate total time taken;
[tex]\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}[/tex]
• To find total travelled distance, use the formula

Photosynthesis and cellular respiration differ in which of the following
ways?
O The main source of chemical energy in cellular respiration is water.
The energy conversion in cellular respiration takes place in the chloroplast.
O The main source of energy in cellular respiration is glucose.
The final product of cellular respiration is electromagnetic radiation.
Answer:
the main source of energy in cellular respiration is glucose.
Explanation:
photosynthesis creates glucose out of co2 h2o and sunlight. while cellular respiration is almost exactly the opposite.
The ways in which photosynthesis and cellular respiration differ is that the main source of energy in the case of cellular respiration is glucose. Hence, Option C is the correct answer.
The photosynthesis and cellular respiration processes are interlinked with a significant relationship. The products of one process act as reactants in the other. Some of the significant differences between both processes are mentioned as follows:
Photosynthesis takes place only in phototrophs such as plants and algae while cellular respiration can take place in all the living forms. Photosynthesis completely takes place in chloroplasts and cellular respiration in Mitochondria. Glucose is made by the process of photosynthesis while glucose is utilized in cellular respiration to make molecules of ATP.Thus, we can conclude that photosynthesis and cellular respiration differ specifically by the main source of energy. Hence, option C is the correct answer.

HOW DOES THE MEIOSIS PROCESS WORK ?
What is different between meiosis and mitosis?
Whats the different between haploid and diploid?
Answer:
Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.
Explanation:
The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.
The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.

Plant cell contain an outermost covering called the cell wall. It protects them from shock and provides mechanical strength to the cell. It is absent in the animal cell.
Chloroplast is also present in the plant cells whereas it is absent in the animal cells. It is a double-membranous structure. A chloroplast is responsible for the process of photosynthesis as it contains chlorophyll pigment. A vacuole is also present in the plant cell and absent in an animal cell.

Explanation:
Active transport uses energy stored in ATP to fuel the transport. ... Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules.
Hope this helps!
If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.
Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.
