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:

umm

Explanation:

Answer:

1. Carbohydrates - provide immediate burst of energy - monosacharrides

2. Lipids - provide source of energy - glycerol or fatty acids

3. Proteins - provide growth and development for our body - amino acids

4. Nucleic Acids - store and pass on genetic information - nucleotides

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.

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.

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.

A heterotrophic prokaryote would derive carbon from the Organic compounds which are present around their environment

Heterotroph are the organism that ought to acquire its carbon in an organic form or an organism that cannot make its very own food and receives its meals with the aid of eating different living things

Chemotroph are the organism that profits power from chemicals  , example bacteria

Phototroph are the  organism that profits electricity through photosynthesis example - flowers

most of the people of heterotrophic microorganisms are chemoheterotrophs that derive both power and carbon from natural compounds.

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

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.

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.
