Example: If u have 1 type of fish in a lake and suddenly the water became salty for some reason, that kind of fish may not survive and if it doesn't there will be no life left in the lake, but if there were multiple types of fish and other animals then some of them would be able to survive and adapt on the change in environment.

Answer:

Lactic Acid Fermentation, which produces the ATP molecule that animals and bacteria need for energy. Lactic acid fermentation occurs when the ATP molecule is created without oxygen.

Alcohol/Ethanol Fermentation, which causes certain sugars to be converted into alcohol and carbon dioxide by bacteria on carbohydrate products/materials.

The statement that accurately explains heredity according to Mendelian inheritance is According to Mendel, heredity is the passing on of a trait from one generation to the next, as either a dominant or recessive allele.

Mendel's laws of inheritance propose that an individual inherits two copies of each gene, one from each parent, and that these genes can be either dominant or recessive. The dominant gene will be expressed in the offspring's phenotype, while the recessive gene will only be expressed if both copies of the gene are recessive.

Therefore, when an organism passes on its genes to its offspring, it can pass on either a dominant or recessive allele for a given trait, depending on its own genotype. The offspring's phenotype will then reflect whether the trait is dominant or recessive and which alleles it has inherited from its parents.

A)Natural selection is indeed a significant force in biological evolution, although it is only one of many potential causes.

Particularly in smaller populations, certain genes or characteristics evolve through random processes like genetic drift. Recall that the alteration with in allele frequencies of the a population across generations is what is meant by biological evolution.

Variation, inheritance, and disparate reproductive success are three straightforward criteria that lead to evolution via natural selection. Natural selection doesn't really affect genotypes directly: It functions by taking advantage of phenotypic variations among population members. Evolution is governed by four principles: variation, inheritance, selection, and time. These are regarded as the elements of natural selection's evolutionary mechanism. Natural selection, genetic drift, gene flow, and mutation are the four driving forces behind evolution.

The eukaryotes have lower gene densities than prokaryotes' statement is false.

Prokaryotic genomes have substantially greater gene densities than eukaryotic genomes, which is defined as the number of genes per million base pairs (also known as a megabase, or Mb). The human genome has 12–15 genes per megabyte or genes.

Compared to prokaryotes, the gene density of eukaryotic nuclear genomes is typically low, but certain eukaryotic lineages (including numerous parasites and endosymbionts) have independently evolved extremely compacted gene-dense genomes.

Prokaryotes are simpler organisms, hence their gene density is larger. Gene density has an inverse relationship with complexity. Eukaryotes, which are more complex organisms, have lower gene densities than prokaryotes, which are simpler organisms.

Plant cells: eukaryotic. Relatively large. Have a nucleus, have mitochondria, sometimes have chloroplasts. Have a large central vacuole and a cell wall.

Small structures in a cell that are found in the cytoplasm (fluid that surrounds the cell nucleus). Mitochondria make most of the energy for the cell and have their own genetic material that is different from the genetic material found in the nucleus.

Mitochondria are known as the powerhouse of the cell because it is responsible for the extracting energy from food through cellular respiration.

Answer:

The process of physiological respiration includes two major parts: external respiration and internal respiration. External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.

Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles. At the end of the bronchioles are air sacs called alveoli, and this is where gas exchange occurs.

An important structure of respiration is the diaphragm. When the diaphragm contracts, it flattens and the lungs expand, drawing air into the lungs. When it relaxes, air flows out, allowing the lungs to deflate.

Common mistakes and misconceptions

Physiological respiration and cellular respiration are not the same. People sometimes use the word "respiration" to refer to the process of cellular respiration, which is a cellular process in which carbohydrates are converted into energy. The two are related processes, but they are not the same.

We do not breathe in only oxygen or breathe out only carbon dioxide. Often the terms "oxygen" and "air" are used interchangeably. It is true that the air we breathe in has more oxygen than the air we breathe out, and the air we breathe out has more carbon dioxide than the air that we breathe in. However, oxygen is just one of the gases found in the air we breathe. (In fact, the air has more nitrogen than oxygen!)

The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are found in the domains Bacteria and Archaea.

There are many components present in prokaryotic organisms. Some of them are discussed below:

Cell wall: This is a tough, protective layer that surrounds the cell membrane in bacteria and archaea. The cell wall is made up of peptidoglycan in bacteria and other materials in archaea.

Flagella: It is a whip-like structure that is used by many prokaryotic cells to move. The flagellum rotates like a propeller, allowing the cell to swim through liquid environments.

Pili or fimbriae: These are short, hair-like structures that extend from the surface of many prokaryotic cells. They are used for attachment to surfaces or other cells.

Capsule: It is a protective layer that surrounds the cell wall of some prokaryotic cells. The capsule is made up of a gel-like material that helps the cell to avoid being engulfed by immune cells such as macrophages.

Ribosomes: They are the site of protein synthesis in prokaryotic cells. Ribosomes are made up of two subunits that come together to form a functional ribosome.In conclusion, components that are present in prokaryotic organisms are cell wall, flagella, pili or fimbriae, capsule, and ribosomes.

Eventually, during the Krebs cycle, the carbon atoms that were initially found in glucose are released as carbon dioxide (CO2).

During glycolysis, glucose is broken down into two molecules of pyruvate, which is a three-carbon molecule. Pyruvate then enters the Krebs cycle, where it is further broken down and oxidized into carbon dioxide (CO2). The CO2 is then released as a waste product through respiration.

Therefore, the carbon atoms originally present in glucose are eventually released as carbon dioxide (CO2) during the Krebs cycle. The CO2 is then carried in the bloodstream to the lungs, where it is exhaled and released into the atmosphere.

This process is important for maintaining the balance of carbon in the atmosphere, as plants take in carbon dioxide during photosynthesis to produce glucose, while animals and other organisms release carbon dioxide during respiration as a waste product.

Abiotic factors are non-living components of an ecosystem that influence the organisms living within it. They include physical and chemical factors such as temperature, sunlight, water availability, soil composition, and minerals. In this case, minerals in the soil are abiotic factors because they are non-living components that directly impact the ecosystem.

Microorganisms in the soil and vertebrates in a stream, on the other hand, are biotic factors. Biotic factors refer to the living organisms within an ecosystem, including plants, animals, fungi, and microorganisms. Microorganisms in the soil contribute to nutrient cycling and decomposition processes, while vertebrates in a stream are living organisms that interact with other biotic components of the ecosystem.
