This is a very interesting question, even somewhat mind boggling.

You’ve heard of mitochondria, right? Organelles in embedded in the cells of macro-organisms, such as ourselves, and that carry their own trimmed down genetic code in DNA? Well their is another organelle in cells that has DNA separate from that of the macro-organism. That is the chloroplast, which is what constitutes the green coloration in plant tissue and is where photosynthesis is done in the plant. Chloroplasts have DNA also.

Now, how is that you may well ask. Why would mitochondria and chloroplasts have their own DNA separate from that of the organism that otherwise completely surrounds and sustains them?

Scientists are pretty convinced by now that it is because both mitochondria and chloroplasts used to be free living organisms on their own. At some point in the early history of life, they became symbiotic and then dependent on unicellular host organisms. The dependence, however, was reciprocated, as neither humans nor plants (with significant exceptions) can live without chloroplasts.

So the main adaptation of plants to do photosynthesis has been to incorporate chloroplasts into their own cells and then further adapt their inputs of water and nutrients to take advantage of that.

Answer:

Explanation:

Sound waves are caused by the vibration of particles in a medium. In a solid, the particles are closely packed and have strong bonds between them, which allows the wave to travel faster due to efficient energy transfer from one particle to another. In contrast, in a gas, the particles are more spread out and have weaker bonds, resulting in slower sound wave propagation.

In outer space, there is no medium for sound waves to travel through since it is a vacuum. Sound waves require particles to vibrate and propagate, and in a vacuum, there are no particles present to propagate these waves. Therefore, sound cannot travel through the vacuum of outer space.

Answer:

- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.

What is binomial nomenclature?

Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.

Binomial Nomenclature also known as the binary nomenclature.

It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.

The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.

Both of this term is written in italic and the genus name is capitalized.

Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.

Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.

These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.

Summary of the limitation binomial nominclature:

- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

The abiotic water pH factor in coastal aquatic habitats is what most inhibits a fishery's productivity.

The majority of aquatic species do not have to contend with extremes in wetness or temperature. Instead, the amount of sunlight available to them and the water's concentration of dissolved oxygen and nutrients are their primary limiting variables.

Ecosystem-specific differences in net primary production exist. They include the amount of solar energy intake, the temperature and humidity, the amount of carbon dioxide, the availability of nutrients, and community interactions.

Answer:

The traits that are determined by polygenic inheritance are not an effect of dominance and recessivity, and do not exhibit complete dominance as in Mendelian Genetics, where one allele dominates another. Instead, polygenic traits exhibit incomplete dominance so the phenotype displayed in offspring is a mixture of the phenotypes displayed in the parents. Each of the genes that contributes to a polygenic trait has an equal influence and each of the alleles has an additive effect on the phenotype outcome. Hope this helps!

Cellular respiration is a process that has three stages to produce 34-38 ATP from a glucose molecule. The processes involved are known as glycolysis, Krebs cycle, and oxidative phosphorylation.

The first one, glycolysis, occurs in the cytoplasm of the cell, after the movement of glucose inside by the action of insulin. This is carried out using glucose, 2 ATP, and 2 NAD+ as reactants to produce 2 molecules of pyruvate, and 8 ATP.

The second one, the Krebs cycle, occurs in the mitochondrial matrix, and from a molecule of 2 acetyl-CoA from 2 pyruvates, 6 NAD+, and 2 FAD, it produces 4 CO2 molecules, 2 GTP that becomes 2 ATP and produces 2 FADH and 10 NADH, which will be used in the following step of the process.

The third one, oxidative phosphorylation, occurs in the mitochondrial membrane, and it from 8 NADH, 4 FADH2, and 6 O2, produces 8 NAD+, 4 FAD+, 6 water molecules, and between 24 to 28 ATP molecules.

Explanation:

The graph shows about the probability of survival for 17-year-old individuals with cystic fibrosis is survival probability has increased because of early screening. The correct option is b.

Mucus builds up in the lungs and digestive tract as a result of the genetic ailment cystic fibrosis, an autosomal recessive disorder. Lung infections and issues with food digestion are brought on by this mucus. The majority of cystic fibrosis cases are discovered through screening during childbirth.

Because the syndrome is recessive, only children who have both homozygous recessive alleles, or (cc), for the disorder, will be affected. Only when both alleles are recessive for that attribute does it affect.

Cystic fibrosis can be treated by early screening. Screening stops the growth of diseases.
