1. Why is cell an open dynamic system?
The exchange of matter or substances between the cell and its environment is dynamic as it varies in direction and rate as per the requirements of the cell. Thus,a cell attains a stead -state wherein the internal conditions of the cell remain constant. Hence, cell is considered to be a open dynamic system
a bird species lives inside a greenhouse, what
would happen to the population size if i limited
the amount of air inside the greenhouse?
Answer:
The greenhouse effect increases temperature, putting the natural instinct to hibernate on hold. Mating seasons rely on warming and cooling trends, as well. Even a slight increase in temperature causes animals to mate earlier.

In a chemical reaction, 1,3-bisphosphoglycerate ADP yields 3-phosphoglycerate plus ATP. What is the delta G for this reaction
Answer:
The reactants have more free energy than the products. In a chemical reaction, 1,3-bisphosphoglycerate + ADP yields 3-phosphoglycerate plus ATP. ... If the delta G of a reaction was -31.45 kJoules, you would know that: The reaction is spontaneous.

A pond organism that is unicellular, contains membrane-bound organelles and possesses a flagellum is a PROTISTA. It is a unicellular kingdom.
The Protista kingdom is composed of eukaryotic single-celled unicellular organisms.
Flagellated protists are microorganisms having a tail-like projection known as flagellum.
The flagellum is a structure used for motion, thereby, in general, flagellated protists are found in moist environments (e.g., ponds, fresh-water, etc).

In Culinary class, Jennifer roads a recipe that noods wited spinach and decides to use salt to propare the leaves. She places the spinach in a solution of 8% salt, which causes the plant cols to shrink
since they normally have an internal salt concentration of 0.9% salt. Which statement best explains why the cells shrink?
Sall causes the cell membrane to swet and absorb water trom the cytoplam
Sat moves from the 8 sal solution into the cell and chemically bind with water
Water moestrom the cell through the cell membrane to an area of lower water concentration
O Water moves from a lower concentration of water in colis cytoplasm into the nucles and colorganelles
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
Osmosis is the movement of water from one region to another through a semi - permeable membrane. A hypertonic solution contains more solute than the cell.
In this case, the external salt solution is hypertonic because it contains a 8% salt concentration whereas the cell contains only a 0.9% salt concentration. As such, water moves out of the cell into the solution.
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.

Mia and Raphael are discussing the ketogenic diet, also known as Keto, as a way of losing weight. Using the Keto method depends on changing the proportions of nutrient macromolecules that are eaten
daily to adjust energy metabolism. Which group of macromolecules can be affected by Keto eating choices, and is used for long term storage plus happens to be insoluble in water?
O carbohydrates
Ads
O nucleic acids
O proteins
The group of macromolecules that can be affected by Keto's eating choices, and is used for long-term storage, in addition to being insoluble in water, is lipid.
The ketogenic diet consists of significantly reducing the amount of carbohydrates ingested daily and adding more fat to the diet.
After about three weeks of reducing carbohydrates from the diet, the body enters a metabolic state called ketosis, turning stored fat as the body's energy source.
Therefore, the ketogenic diet can bring benefits to the individual, such as accelerated weight loss and prolonged satiety, but it can also be a difficult diet to follow for long periods, as it is more restrictive.
The ideal, then, is always to seek specialized help when you want to achieve some aesthetic or health goal related to weight loss, so that the professional can develop a diet focused on the needs and individualities of each one.

Which of the following are characteristics of the tundra biome? (Choose all that apply.)
much rainfall throughout the year
low biodiversity
very cold temperatures
lack of trees
A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.
What is Tundra Biome?The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.
The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.
Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.
Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

How would an error during mitosis cause a different effect on the body than an
error during meiosis
A mistake in the process of mitosis leads to the development of the daughter cells having chromosomes without segregation.
What is mitosis?A cell undergoes cell division by replicating its chromosomes, segregating chromosomes, and creating two identical nuclei during the mitotic phase. The cell organelles are divided equally between two daughter cells with the same set of genomes after mitosis.
Prophase, prometaphase, metaphase, anaphase, and telophase are the main four stages. Meiosis creates cells that are genetically distinct from the parent and have half as much DNA as mitosis, which divides a single "parent" cell into two genetically identical cells.
Therefore, mitosis is a process used in the somatic cells whereas miosis is in fertilization.

Stored chemical energy is broken down and released in the cytoplasm.
Stored chemical energy is broken down and released in the cytoplasm.
Stored chemical energy is broken down and released in the mitochondria.
Stored chemical energy is broken down and released in the mitochondria.
Stored chemical energy can be used immediately and is released in the cytoplasm.
Stored chemical energy can be used immediately and is released in the cytoplasm.
Stored chemical energy can be used immediately and is released in the mitochondria.
Answer:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. The energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
So the answer is Stored chemical energy is broken down and released in the mitochondria.
Explanation:
In cellular respiration, stored chemical energy is broken down and released in the mitochondria. The correct option is B.
What is mitochondria?Mitochondria are the membrane-bound organelles that create the maximum of the chemical energy necessary to power the biochemical reactions of the cell.
The mitochondrial energy is stored in a small molecule referred to as adenosine triphosphate (ATP).
Cellular respiration is the way by which organic fuels are oxidized in the presence of an inorganic electron acceptor, encompassing one as oxygen, to give enormous amounts of energy and pressure the majority production of ATP.
Cellular breathing is the way by which cells in plants as well as animals break down glucose and convert it into power, which is then used to perform work.
The goal of cellular respiration is simple: to provide the energy that cells require to function.
Thus, the correct option is B.
