Hello. You forgot to put the image necessary for this question to be answered. The image is attached below.

Answer:

This is a connective tissue that has non-stratified and non-keratinized squamous epithelium. In addition, it has live epithelial cells.

Explanation:

As already mentioned, the image below shows connective tissue. this tivo has the function of giving support and filling empty spaces between different tissues, allowing a strong support in the body. In the image, we can notice the presence of non-stratified and non-keratinized squamous epithelium, commonly found in regions that are subjected to friction such as mouth, esophagus and vagina, for example.

The image to correctly identify the type of tissue is missing. Thus, we will make sure we give a concise explanation of what Tissue is all about.

Tissue is a collection of cells with homologous structures that work harmoniously as a unit. A nonliving substance (known as the intercellular matrix) fills the gap space between these cells which varies from one tissue to another.

There are four fundamental types of tissues in the body which are as follows:

With each made up to carry out a certain specific purpose(s).

The epithelial tissue serves as a protective barrier and facilitates ion and molecule diffusion. They are found in the basal membranes, line the body cavities, and can also be found in the gap junctions

Connective tissue is the most prevalent type of tissue in the body. They are composed and are made up of cells and an extracellular matrix(which has protein fibers as well as a ground substance).

They can be found in the blood, embryo, tendons, and ligament, etc.

The muscular tissue is known as elastic tissue. This implies that they can be stretched and relaxed. i.e. They have the ability to contract.

This contraction factor is brought about by the action of the actin and myosin filaments present in them. They can be found in the skeletal muscles, smooth muscles, and cardiac muscles.

The nervous tissues consist of cells whose main active function is the transfer of electrical signals around the body. The nervous tissues consist of neurons and the glia. The neurons are comprised of long finger-like projections known as the axon and the dendrites whose role is to transfer signals, an impulse away from the neurons, and carry information(s) back to it.

From the above explanation, we can conclude that we now have a better understanding to correctly identify tissue types.

Answer:

The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.

Explanation:

Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.

Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.

When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

Nitrogen fixation is a significant process in the biochemistry of life. However, the chemical process is not spontaneous; thus, a large activation energy barrier must be overcome.

The biological systems overcome the high activation barrier of nitrogen fixation by binding and hydrolyzing ATP.More than 100 energy molecules are required for the reduction of N2 to NH3 through the nitrogen fixation process. A significant amount of energy is required for the conversion of nitrogen gas to other forms of nitrogen in order to enter the biogeochemical cycle.

Thus, the nitrogenase enzyme complex facilitates the reduction of nitrogen gas to ammonia in biological nitrogen fixation.The high activation energy barrier required to overcome this reaction's thermodynamic stability is assisted by the binding and hydrolyzing of ATP.

Before converting protein to glucose or fat, the amino group must be removed.

Proteins are composed of amino acids, and when the body needs energy, it can convert proteins into glucose through a process called gluconeogenesis or into fat through lipogenesis. However, before proteins can be utilized in these metabolic pathways, the amino group \((-NH_2)\) needs to be removed. This process is called deamination.

Deamination occurs primarily in the liver. The liver enzymes remove the amino group from the amino acids, resulting in the formation of ammonia \((NH_3)\). However, ammonia is toxic to the body, so the liver converts it into a less toxic substance called urea. Urea is then transported to the kidneys and excreted from the body through urine.

Using the results of his experiments with pea plant crosses, Gregor Mendel discovered: A) the principles of dominance, segregation, and independent assortment.

In this famous experiment, Mendel cross- pollinated pea plants based on their different features to make important discoveries on how traits are inherited between the generations.

Mendel crossed the pure lines of pea plants. Dominant traits, like purple flower color, appeared in first-generation hybrids (F1), whereas recessive traits, like white flower color were masked. But recessive traits reappeared in second-generation (F2) pea plants in ratio of 3:1 (dominant to recessive).

The experiment allowed Mendel to conclude on two laws of Inheritance; that are Law of Segregation and Law of Independent Assortment.

According to Kepler's third law, T2 R3, the cube of the mean distance between the planet and the Sun (R) and the square of the time period (T) are exactly related. As a result, the planet's orbital period lengthens by a factor of two.

The orbital period increases and the gravitational pull decreases with a doubled distance from the sun. Depending on how far away from the Sun a planet is, it will have a different orbital speed.

A planet moves more quickly and experiences a stronger gravitational attraction as it gets nearer to the Sun.

It moves in its orbit more slowly the further it is from the Sun because of the Sun's weaker gravitational attraction.

Therefore, the planet's orbital period lengthens by a factor of two.

Even if all the cells have the same DNA they biochemical function are different, that's because differents sets of genes must be turned on and off in each cell type by the action of enzymes and other molecules. Each cell have the same 20,000 or so genes but they are biochemically selected by the action of molecules as hormones and chemical signaling. Therefore, different cells use different parts of the DNA code as directions.

Genes are a section of DNA that are in charge of different functions like making proteins. Long strands of DNA with lots of genes make up chromosomes. DNA molecules are found in chromosomes. Chromosomes are located inside of the nucleus of cells.

A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides). Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.

If the mordant (usually iodine) is not applied during the Gram staining process, E. coli will appear as a pink or red color under the microscope.

This is because the primary stain, crystal violet, will not be properly trapped in the bacterial cell wall without the mordant. In a complete Gram staining process, E. coli, which is a Gram-negative bacterium, would appear pink after the application of the counterstain safranin.
