Wildlife and forensic genetics contribute to the protection of endangered species by ensuring that plants and animals aren't caught and transported illegally and the fingerprinting ensures the organisms are adequately monitored.

This refers to the type of organism which has a high risk or chance of becoming extinct in the nearest future as a result of some factors such as over exploitation, habitat destruction etc.

The use of wildlife and forensic genetics ensure that the DNA is gotten from organisms and several investigations and amplifications are done so as to get their origin and the areas in which they are natives of.

This act helps to control the illegal movement of some species to other parts for various purposes such as finances, aesthetics etc. This could lead to over exploitation and endangering of the species which helps to curb it.

Answer:

False. There are 20 amino acids, but 64 possible codons.

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.

• The end codons are UAA, UAG, UGA.

The tissue type that forms binding, supporting, and transporting structures and usually contains collagen for strength is Connective tissue. Thus option C is correct answer.

Connective tissue is a type of tissue that provides support as well as structure to the body. It is responsible for forming the binding, supporting, and transporting structures of the body. Connective tissue is composed of cells and an extracellular matrix, which contains collagen, elastin, and other fibers that give it strength and flexibility.

Collagen is the most important protein in connective tissue and is responsible for its strength. It provides a scaffold for other proteins and cells to attach to and gives the tissue its structure. Connective tissue can be found in various forms throughout the body, such as tendons, ligaments, cartilage, bone, and blood.

Unlike epithelial tissue, which covers and lines body surfaces and organs, connective tissue is found throughout the body and performs a variety of functions. It is responsible for connecting and supporting tissues and organs, providing protection and insulation, and transporting nutrients and waste products throughout the body.

In summary, the connective tissue is the tissue type that forms binding, supporting, and transporting structures in the body and contains collagen for strength. It is a diverse tissue type that is essential for maintaining the structure and function of the body.

Explanation:

Horse tail (Equisetum) and Mucor  are not kept in the same kingdom as they belong to different kingdoms because they exhibit distinct characteristics and are classified based on their evolutionary history, cellular organization, and reproductive strategies.

Horse tails, also known as horsetails or Equisetum, are members of the plant kingdom, specifically the division Equisetophyta.

They are vascular plants that reproduce by spores.

Horse tails have a unique appearance, with jointed stems, whorls of tiny scale-like leaves, and reproductive cones at the tips of their stems.

They have a complex life cycle with alternation of generations, including both a sporophyte (dominant diploid phase) and a gametophyte (haploid phase).

Their cells have a rigid cell wall composed of cellulose, a characteristic feature of plant cells.

On the other hand, Mucor belongs to the kingdom Fungi.

Mucor is a genus of fungi within the phylum Zygomycota.

Fungi are eukaryotic organisms that lack chlorophyll and obtain nutrients through absorption.

They have a filamentous body structure called mycelium, composed of thread-like hyphae.

Mucor reproduces asexually through the production of spores, which are formed by the fusion of genetically distinct hyphae.

Fungi are heterotrophic, meaning they obtain their nutrients by breaking down organic matter in their environment.

The differentiation of horse tails (plants) and Mucor (fungi) into separate kingdoms is based on fundamental differences in their cellular organization, nutritional strategies, and reproductive mechanisms.

While both horse tails and Mucor are multicellular organisms, they belong to distinct lineages of life with diverse evolutionary histories, leading to their classification in separate kingdoms.

The respiratory system characteristics shared by fish, frogs, sponges, and earthworms are gas exchange across a moist respiratory surface.

Which organisms respire through their moist respiratory surface?

The moist respiratory surface of earthworms and amphibians like frogs is used for breathing. They belong to a class of land-dwelling creatures with skin that is permeable to gases. Earthworms, sponges, fish, and frogs may breathe through their permeable skin, which must be kept moist.

Earthworms reside underground in the wet soil, whereas amphibians are creatures that live in or near water. The skin of animals that can breathe through their skin is moist, and the capillaries, which are tiny blood veins, are located near the skin's surface. These little blood arteries supply oxygen to the body's numerous tissues and carbon dioxide to the epidermis.

The only non-plant source of carbohydrates is foods derived from animals. In contrast, animals do not have the ability to produce carbohydrates through photosynthesis.

carbohydrates are a class of macronutrients that are commonly found in plant-based foods such as fruits, vegetables, grains, and legumes. Plants have the ability to synthesize carbohydrates through photosynthesis, converting sunlight, water, and carbon dioxide into glucose and other sugars.

They obtain carbohydrates by consuming plant-based foods or by consuming other animals that have consumed carbohydrates. Animal-derived foods, such as meat, eggs, and dairy products, may contain small amounts of carbohydrates if the animals have consumed plant material.

It is important to note that while animal-derived foods may contain some carbohydrates, they generally provide a much lower carbohydrate content compared to plant-based foods. Animal-derived foods are typically known for their protein and fat content rather than their carbohydrate content. Therefore, if someone is looking to primarily consume carbohydrates in their diet, plant-based foods are the main source to consider.

The only non-plant source of carbohydrates are foods derived from animals, such as milk and dairy products.

Carbohydrates are macronutrients that are commonly found in plant-based foods, including fruits, vegetables, grains, legumes, and roots. These sources provide a wide range of carbohydrates, including sugars, starches, and fiber. However, in terms of non-plant sources, animal-based foods do not typically contain significant amounts of carbohydrates. Animals do not synthesize carbohydrates in the same way plants do through photosynthesis.

The primary exception to this is milk and dairy products. Milk contains a natural sugar called lactose, which is a disaccharide composed of glucose and galactose. Dairy products, such as cheese and yogurt, also retain lactose from milk. While other animal-derived foods, such as meat, poultry, and seafood, contain negligible amounts of carbohydrates, they are primarily sources of protein and fat.

It's worth noting that some processed foods may contain added carbohydrates, including sugars or starches derived from plant sources. However, when considering natural food sources, the only significant non-plant source of carbohydrates is milk and dairy products.

Falso (este principio es la base de la energía hidráulica la cual ha sido utilizada por siglos)

Explanation:

La energía hidráulica es un tipo de energía obtenida a partir del aprovechamiento de las corrientes de agua. La humanidad ha utilizado desde hace siglos la energía hidráulica producida por la corrientes de aguas de los ríos conectados con pequeña represas a fin de mover molinos y rotores, y así convertir la energía hídrica en energía mecánica, la cual a su vez puede ser utilizada para moler granos de cereales (molinos harineros) y también (más recientemente) para la generación de energía eléctrica. Las centrales hidroeléctricas representan la principal aplicación de la energía hidráulica en la actualidad. Las centrales hidroeléctricas utilizan el mismo principio que estos antiguos molineros harineros para producir energía, aprovechando la energía potencial del cauce del agua y su caída a un nivel inferior del cauce. En el caso de las centrales hidráulicas, el agua que cae se hace pasar por turbinas hidráulicas conectadas a un generador que produce energía eléctrica. La energía hidráulica representa un tipo de energía limpia con un gran potencial de rendimiento energético.
