The look of an organism according to its genes is called as phenotype of an organism.
Explanation:
The genetic makeup of an organism is usually called as the genotype whereas the physical morphological structure of an organism is termed as a phenotype of an organism. The phenotype usually depends upon the genotype of the organism; this genotype is not visible and hence cannot be known easily.
Whereas a phenotype is easily visible. To know the genotype of an organism the unknown organism should be crossed with a true breeding cross.

#SPJ2
Final answer:
Cells use cellular respiration to acquire energy by converting carbohydrates and oxygen into ATP, the principal energy carrier within the cell. The correct option is A.
Explanation:
To power the activities of the cell, cells use cellular respiration to acquire energy in the form of adenosine triphosphate (ATP). ATP serves as the principal energy carrier within the cell. During the process of cellular respiration, cells convert biomolecules like carbohydrates into energy. The carbohydrates react with oxygen, which is an essential reactant in this process, and as a result, carbon dioxide and water are produced alongside ATP. The ATP produced is then utilized to fuel various cellular functions, serving as the energy currency of the cell. It's crucial to understand that although oxygen is required for aerobic respiration, ATP can also be produced in the absence of oxygen through anaerobic processes like fermentation.

polar bear have small ears because
Answer:
The polar bear's small ears and tail offer less surface area than large ears or tails, and help maintain body warmth. Fat. Polar bears have a layer of fat that can be four inches (10 cm) thick. Although their fur is the primary source of insulation, the fat helps keep heat in as well.
Polar bears have small ears to minimize heat loss in their cold Arctic habitat, complemented by thick fur and blubber for insulation.
Polar bears (Ursus maritimus) have small ears as an adaptation to their Arctic ecosystem. The small size of their ears serves to minimize heat loss in an environment where maintaining body temperature is critical. Large-eared animals, like elephants, need to disperse heat due to their small surface-to-volume ratio, but for polar bears, conserving body heat is more important.
This is similar to why you wouldn't find animals like wild mice, which are small and lose heat quickly, living in the poles. Additionally, polar bears have developed thick fur and a dense layer of blubber under their skin to further reduce heat loss and maintain a warm body temperature amidst icy conditions.

B:They are stored in vacuoles and removed from the cell.
C:Most become reactants in protein synthesis.
D:They are released into the cell cytoplasm.
Answer: D:They are released into the cell cytoplasm.
Explanation: Krebs cycle also known as the citric acid cycle or the TCA cycle is a biochemical reaction utilized by all aerobic organisms. Krebs cycle cannot directly produce significant chemical energy which is adenosine triphosphate. The cycle Instead, produces NADH and FADH2 which are electron carriers, which then enters the respiratory cycle.
It is the major aim of the Krebs cycle to synthesis the electron carriers that is released into the cytoplasm to be used in cellular respiration.
The Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is a central metabolic pathway in cellular respiration.
The correct option is A.
It takes place in the mitochondria of eukaryotic cells and is involved in the breakdown of carbohydrates, fats, and proteins to produce energy in the form of adenosine triphosphate (ATP). During the Krebs cycle, acetyl-CoA (produced from the breakdown of glucose, fatty acids, or amino acids) enters the cycle and undergoes a series of chemical reactions, resulting in the generation of ATP, carbon dioxide (CO2), and reduced electron carriers (NADH and FADH2). These reduced electron carriers are then used as reactants in the electron transport chain, the final stage of cellular respiration.
In the electron transport chain, the electrons carried by NADH and FADH2 are passed along a series of protein complexes, leading to the production of more ATP through oxidative phosphorylation. This process occurs in the inner mitochondrial membrane.
