Answer:
B. Evaporation
Explanation:
in a chemical reaction bonds in the reactants molecules are broken and new bonds are formed to yield products. how does an enzyme make this happen an optimal rate in a cell?
Answer:
A. It increases the amount of energy needed to break the bonds in the substrate.
Explanation:
Enzymes are known to be protein-based catalyst. It helps to speed up the chemical reactions that take place in the human body. They actually bind molecules and work in ways to alter chemical reactions. These enzymes are needed for food digestion, reproduction, healing diseases, blood coagulation, etc.
Enzymes help to increase the rate of reaction by lowering the activation energy. Certain enzymes can work to convert substrate to product at million of times faster. As a catalyst, it increases the energy needed to break bonds found in the substrate. This makes the reaction to occur at a faster rate.
Cellular respiration is an exothermic reaction and photosynthesis is an endothermic reaction. How does the required activation energy compare for these two reactions?.
Because the products are at a lower energy level than the reactants, cellular respiration requires less energy to start the reaction.
The activation energy is the bare minimum of energy required for compounds to undergo a chemical reaction. In an exothermic reaction, breaking bonds in the reactants requires less energy than the energy produced when new bonds form in the products. The term "exothermic" literally means "give out heat." Exothermic reactions occur during cellular respiration.
An endothermic reaction, on the other hand, requires more energy to break bonds in the reactants than is released when new bonds form in the products. The term "endothermic" literally means "take up heat." Exothermic reactions occur during cellular respiration.

A-Niche
B- Habitat
C- Community
D- Ecosystem
Answer:
B. Habitat
Explanation:
Ecosystems are geographical regions made up of biotic factors (plants, animals, bacteria) and non-living or abiotic factors (rocks, rainfall, temperature).
They live in groups called communities within their ecosystem and occupy a specific place in their community, a niche - here, they contribute to nutrient cycling and energy flow. They may often wander in search of food, or shelter in a region known as a habitat.

What is the step of cell division where 2 identical daughter cell are formed?
Answer:
It's MITOSIS.
Explanation: We are also learning about this in class.
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
In mitosis of the cell cycle, a eukaryotic cell undergo nuclear division followed by cytoplasmic division results form two genetically identical daughter cells. Mitosis It consist of five phases: prophase, prometaphase, metaphase, anaphase, and telophase.
What is mitosis ?The process in which somatic cell undergo equational division where equal number of daughter cell produced from their parent cell.
Here the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes become half and the nucleus of a cell is divided into two nuclei having equal amount of genetic material.
nuclear division is followed by cytoplasmic division after the separation of the nucleus. It is important for the growth of the cells and the replacement of worn-out cells.

4. The process by which autotrophs use energy from sunlight to build carbohydrates is called ____________________.
Answer:
photosynthesis
Explanation:
Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis. Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules.
pasteur's experiment provided conclusive evidence to reject the spontaneous generation hypothesis, which states that cells arise from nonliving material. as a consequence, his results supported the all-cells-from-cells hypothesis. which element of pasteur's experimental design was most important and why? see section 1.2 (page) .
The Experiment name is 'swan neck flask'.
Since only one of his two treatments employed the same type of nutritious broth and flask, only one of his two treatments was exposed to preexisting cells.
Nutrient Broth- A common culture medium for undemanding microorganisms is nutrient broth. Numerous standardized techniques for analyzing meals, dairy products, water, and other items advocate it.
Pre-existing Cell- All cells originate from previously existing cells, according to the third component of the cell theory definition. This implies that cells are not created spontaneously, as the term "spontaneous genesis" implies. Current cells are constantly used to create new ones.

Answer.
Type your answer her to focus a microscope using the high-power lens you have to use the focus adjustment
knob but be careful because if you crank down too hard you can damage the microscope and the slide
Is my answer right
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.

Cell Length of one side Area of one side of the cube (l × w) Surface area (area of one side × 6 sides) Volume (l × w × h) Surface area / volume Ratio of surface area to volume (for example, 5:1) A 1 cm B 2 cm C 3 cm
The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = 3 : 1
surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)
volume= 1 cm³ (1cm x 1cm x 1cm)
2. Surface area to volume ratio = 6 : 1
surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)
volume= 1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
