Answer:Madagascar Pochards
Explanation: The Madagascar Pochard, or sometimes known as the Madagascan pochard, is a very rare diving duck of the genus Aythya. Thought to be extinct in the late 1990s, individuals of the species were recovered in 2006 near Bemanevika, Madagascar, at Lake Matsaborimena. The species is only found in Madagascar's interior marshes, where it is endemic. The sole wild populations are currently found in Lake Sofia and Lake Matsaborimena. Meanwhile, there are slightly over 50 pochards at Bemanevika.

what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

Compare and contrast the skeletal body system with immune system
Abstract
In the last two decades, numerous researchers have focused on elucidating the relationship between the skeletal and immune systems with respect to their regulatory mechanisms. It has now become clear that osteoclasts are derived from the same myeloid precursor cells that can differentiate into macrophages and myeloid dendritic cells. In addition, bone and immune cells coexist in the common microenvironment of the bone marrow and are thus influenced by similar mediators. Discovery of a common regulatory mechanism via the receptor activator of nuclear factor kappa-B ligand (RANKL)–receptor activator of NF-κB (RANK)–osteoprotegerin (OPG) axis in both the bone and immune system has not only increased understanding of the fundamental processes of bone homeostasis but has further crystalized understanding of the definitive regulatory correlation between bone and immunity. Moreover, many of the soluble mediators produced by immune cells, including cytokines, chemokines, and growth factors, regulate the activities of osteoclasts and osteoblasts. This increased recognition of the complex interactions between the immune system and bone has led to the development of the interdisciplinary field of osteoimmunology. In this review, we summarize the characteristics of bone cells and the soluble mediators responsible for crosstalk between the skeletal and immune systems. A more complete appreciation of the interactions between immune and bone cells should lead to better therapeutic strategies for diseases that affect either or both systems.
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): glucosa 90, trigliceridos 120, hemoglobina,14 y acido urico 6.¿ cual de ellos corresponde a un lipido?
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): El que corresponde a lípidos son los triglicéridos.
Los resultados del estudio de sangre al que fue sometido Carlos son:
glucosa = 90 mg / ml triglicéridos = 120 mg / ml hemoglobina = 14 mg / ml ácido úrico = 6 mg / mlA partir del resultado dado, la opción que corresponde a los lípidos son los triglicéridos.
Los triglicéridos son lípidos (grasas cerosas) que proporcionan energía al cuerpo. Los triglicéridos son producidos por nuestro cuerpo y se obtienen de las comidas que ingerimos. Un triglicérido es un tipo de lípido compuesto por glicerol y tres moléculas de ácidos grasos.
La glucosa tiene la fórmula molecular C6H12O6 y es un azúcar simple. La glucosa es el monosacárido más ubicuo que es un tipo de carbohidrato. La glucosa es producida principalmente por plantas y algas cuando realizan actividad fotosintética a partir del agua y el dióxido de carbono con la ayuda de la luz solar, donde se utiliza para crear celulosa en las paredes celulares.
La hemoglobina es una proteína que se encuentra en los glóbulos rojos (RBC) que transporta oxígeno a los órganos y tejidos y transporta el dióxido de carbono (CO2) de los órganos y tejidos de regreso a los pulmones.
El ácido úrico es un producto de desecho que puede detectarse en la sangre. Se forma cada vez que el cuerpo descompone las purinas. La mayor parte del ácido úrico se disuelve en la sangre, viaja a través de los riñones y se excreta en la orina.
Por tanto, de la explicación anterior, podemos concluir que el resultado que corresponde al lípido son los triglicéridos.

What are the three kinds of muscle tissues? Where is each located?
Answer:
Cardiac, smooth, and skeletal muscle tissues.
Explanation:
Muscle tissue is classified into three types: cardiac, smooth, and skeletal. Cardiac muscle cells are found in the heart's walls, are striped (striated), and are under involuntary control. Except for the heart, smooth muscle fibers are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are similarly under involuntary control. Skeletal muscle fibers are found in muscles that are connected to the bones. They have a striated look and are controlled voluntarily.
Answer:
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control

What would be the speed of a wave with low tension, a distance of 8.5 cm and a time of 3.25 seconds?
The speed of the wave will be 0.026 m/s
The speed of a wave is the distance traveled by a given point on the wave (such as a crest or trough) in a given interval of time.
Speed is given by the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
From the question,
Distance = 8.5 cm
First, convert this to meter
Recall:
100cm = 1m
∴ [tex]8.5 cm = \frac{8.5}{100}[/tex] m
8.5 cm = 0.085m
and
Time = 3.25 seconds
Now, putting the above parameters into the equation
[tex]Speed = \frac{Distance}{Time}[/tex]
∴ [tex]Speed = \frac{0.085}{3.25}[/tex]
Speed = 0.026 m/s
Hence, the speed of the wave will be 0.026 m/s

Name four ways synthetic fibers are different from each other?
*forensic science*
Synthetic fibers can vary greatly from one another. The main reason they can have such varying characteristics is that they can be of four distinct types.
Synthetic fibers are those that cannot be found in nature, but rather are created by man. They can be of four types:
Nylon RayonPolyesterAcrylicRayon is one of the types of synthetic fibers created by man. One of the weaker fibers, It is commonly referred to as synthetic silk, having many properties similar to those of silk. It is the result of wood pulp being fused with cotton or wool and is commonly used to create beddings and other home decorations, in varying colors.
Nylon shares few, if any, characteristics with rayon. It is a strong and elastic synthetic fiber. In fact, nylon is stronger than steel wire, even though it is created from water, coal and air. Nylon can be found in tents, climbing equipment, toothbrushes, and many more everyday appliances.
Polyester is a stranger form of synthetic fiber. As its name implies, it is formed from the repetition of esters. Polyester is often used for dressing, given its wrinkle-free properties and resistance. However, many kinds of polyesters exist, leading to its use in bottles, wires and more.
Finally, Acrylic is the final kind of synthetic fiber. Acrylic is a fiber which is normally used to replace wool. Acrylic can be seen used in blankets and sweaters. It is also often used to create panels that will imitate glass, which shows exactly how flexible and useful synthetic fibers can be.
