Answer:
The correct answer would be:
Neither of these response options accurately features the anaerobic electron transport chain.
Explanation:
The anaerobic respiration system vibrated by an electron transport chain is a mechanism that anaerobic bacteria have to maintain their respiration.
This mechanism does not require oxygen in the atmosphere, that is why it is said to be an anaerobic mechanism.
Bacteria do not all need oxygen in the environment to live, some need that oxygen is not exactly present (strict anaerobes) or that it is at low partial pressures (facultative anaerobes).
This mechanism is very characteristic in its location since it is located in the inner membrane of the mitochondria, that is why it will decide to indicate that option as the correct one.
(a) Aquatic ecosystems are rich in diversity. The life inside water is largely influenced by various abiotic factors. The abiotic factors are the chemical and physical components of an environment that affect the organisms living there. The primary abiotic factors that affect the life underwater are temperature, light and availability of oxygen.
(b) Oxygen available to the aquatic organisms is a detrimental factor. If less oxygen is available underwater aquatic animals will not be able to respire and die.
Light is also an important abiotic factor for underwater organisms especially for the aquatic plants. the aquatic plants underwater will not be able to make their food by photosynthesis if proper light is not available.
Temperature also plays an important role. Too low or too high temperature affects the metabolic activities of the organisms.
Depth of water body affects the availability of light and oxygen to the aquatic organisms. Shallow water bodies have light available to more aquatic organisms.
Answer:
is the process of breeding only organisms with desirable traits
Explanation:
Explanation:
During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.
These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.
