Answer:

Geothermal

Explanation:

The answer would be geothermal because you have to drill down into the earth to harness the heat needed for it to create energy.

Answer:

a) introns

Explanation:

In molecular terms, a gene can be defined as a segment of DNA that is expressed to give a functional product, which can be an RNA or a polypeptide. Large amounts of non-coding DNA can be found within the majority of eukaryotic genes. These genes have a divided structure in which the segments of coding sequence (called exons) are separated by non-coding sequences (called introns). The complete gene is transcribed to produce a long molecule of RNA (called pre-RNAm) which will suffer a series of changes before leaving the nucleus. One of these modifications is called splicing, in which the introns are removed. Therefore, only exons are included in the RNAm.

The biochemical analysis of nuclear extracts has revealed that splicing occurs in big complexes, called spliceosomes, formed by small nuclear ribonucleoproteins (snRNPs) and 5 types of small size nuclear RNA (RNAsn).

In areas that have cold winters, some common bird foods, such as nectar and insects, may not be available year-round. Birds that eat those foods must fly south to find food to survive. Other birds that eat seeds or bugs that live under tree bark often hang around, since they can continue to find food all winter long.

If some mice have inherited a genetic mutation that causes them to have a band of white fur around the middle of their bodies, it is most likely that an ancestor of these mice also had the same genetic mutation that caused the band of white fur.

Genetic mutations are changes in DNA sequence that can be inherited by offspring from their parents. If a mutation passed down from the parent to its offspring, then next generations will also have the same mutations. The white fur band presence suggests that the mutation for this trait has been inherited through multiple generations of mice.

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.

Answer:

More mitochondria in athlete's muscle cells.

Explanation:

There is a significant difference in the muscle cell of an Olympic athlete as compared to an average adult because Olympic athlete has more number of mitochondria present in their muscles cells as compared to muscle cell of an average adult. The main reason for this is that Athlete performs harder activities so they required more energy to do their activities so their muscles cells have large number of mitochondria to provide more energy for their activities.

Meiosis is the first step in sexual reproduction during which crossing over and recombination develops new combinations of genes on chromosomes. When gametes are produced they under go random fertilization and offsprings with great genetic variations are produced.

This leads to evolution of species on the planet.

Explanation:

Answer:

When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.

Explanation:

Have a great day, and spread some positivity!

A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.

The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.

The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.

Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.

If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.

Sample Response: The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.

Bacteriorhodopsin

Explanation:

Purple Halobacterium species owe their color to bacteriorhodopsin, a light-sensitive protein.

Answer:

Both prokaryotic and eukaryotic cells have structures such as cell membranes, cytoplasm, and ribosomes. However, there are some differences in the structure and organization of these organelles between prokaryotic and eukaryotic cells.

In prokaryotic cells, the genetic material is not enclosed in a membrane-bound nucleus, but instead exists as a single circular chromosome in the cytoplasm. Eukaryotic cells have a true nucleus that houses the DNA, as well as additional membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.

Prokaryotic cells also typically have a cell wall made of peptidoglycan, which is not found in animal cells. Plant cells have a cell wall as well, but it is made of cellulose. Eukaryotic cells may also have specialized structures such as chloroplasts (in plant cells) and cilia or flagella for movement.

Explanation:

The four types of lipids, namely fats, phospholipids, waxes, and steroids, play distinct roles in various biological processes. Fats are primarily involved in energy storage, while phospholipids form the structural basis of cell membranes. Waxes provide protection and waterproofing for plants and animals, and steroids serve as signaling molecules and are involved in various physiological functions.

1. Fats: Fats, also known as triglycerides, are a type of lipid that play a crucial role in energy storage. They are composed of glycerol and three fatty acid chains. Fats are stored in adipose tissue and serve as a long-term energy reserve. During times of energy deficiency, fats are broken down through a process called lipolysis to release energy.

2. Phospholipids: Phospholipids are a major component of cell membranes. They consist of a glycerol molecule, two fatty acid chains, and a phosphate group. The unique structure of phospholipids allows them to form a lipid bilayer in cell membranes, with the hydrophobic fatty acid tails facing inward and the hydrophilic phosphate heads facing outward. This arrangement creates a selectively permeable barrier that controls the movement of substances in and out of the cell.

3. Waxes: Waxes are a type of lipid that serve protective functions in both plants and animals. They are composed of long-chain fatty acids and a long-chain alcohol. In plants, waxes form a waterproof coating on the outer surfaces of leaves, stems, and fruits, preventing excessive water loss and providing protection against pathogens. In animals, waxes are found in structures such as the ear canal, providing lubrication and protection against foreign particles.

4. Steroids: Steroids are a class of lipids characterized by a four-ring structure. They have diverse roles in the body, including serving as signaling molecules and regulating various physiological processes. For example, cholesterol, a type of steroid, is a precursor for the synthesis of steroid hormones such as estrogen, testosterone, and cortisol. These hormones play essential roles in reproduction, development, and metabolism.

Overall, the four types of lipids - fats, phospholipids, waxes, and steroids - each have distinct functions and contribute to various biological processes in organisms.
