Transmission electron microscope - The transmission electron microscope uses electrons instead of light. a light microscope is limited by the wavelength of light. TEMs use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with a light microscope. The possibility for high magnifications has made the TEM a valuable tool in both medical, biological and materials research.Compound light microscope - Microscope with more than one lens and its own light source. There are ocular lenses in the bonicular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. To ascertain the power of magnification of a compund light microscope, it's needed to take the power of the objective lens and multiply it by the eyepiece which is generally 10x. Although sometimes found as monocular with one ocular lens, the compound binocular microscope is more commonly used today. The first light microscope dates back to 1595, when Zacharias Jansen created a compound microscope that used collapsing tubes and produced magnifications up to 9X.

Answer:

When the cell is in a hypotonic environment, it is swollen because there is a movement of water from the middle into the cell. When it is transferred to a hypertonic environment there is a movement of water out of the cell which causes the cell to become dehydrated and for this reason it contracts.

sea star      is the answer

It's not all of the above.  I just took the test.  so you have to choose just one.

Answer: (C) energy

Earth is an open system with respect to energy because the earth receives energy from the sun in the form of solar energy. This energy is absorbed by the oceans and terrestrial land. The solar energy in the form of thermal energy heat up the oceans and the terrestrial land which results in the release of thermal energy by the oceans and terrestrial lands. Some of this thermal energy is reflected back to the exterior of the earth which supports the fact that earth is an open system.

The butterfly-shaped area observed in the cross-section of the spinal cord is the gray matter, containing neuronal cell bodies and dendrites. It serves as a crucial processing center for sensory and motor information within the spinal cord.

When observing a cross-section of the spinal cord under a microscope, you can identify the following:

Final answer:

The specificity of catechol oxidase is determined by how well a substrate can bind to the iron center of the enzyme and how it interacts with the active site. The molecular structure of catechol allows it to form certain complexes with iron that are integral for the enzyme's specificity.

Explanation:

Factors Influencing the Specificity of Catechol Oxidase

The specificity of the enzyme catechol oxidase is influenced by the molecular structure of its substrates, such as catechol and hydroquinone. When catechol coordinates to the ferric center of the enzyme, it can do so in a monodentate or bidentate fashion, which suggests the structure of the substrate plays a crucial role in the enzyme's specificity. Comparing the structures of catechol and hydroquinone, it is the ability of catechol to coordinate with the iron center in such fashion that differentiates it from hydroquinone regarding enzyme binding and reaction.

Furthermore, the specificity of catechol oxidase also seems to be driven by how well the substrate fits within the active site and interacts with key amino acids and the iron center. The oxidation of catechol to o-quinone, where dioxygen binds and reacts with the catechol complex, also indicates that the catecholate form of the ligand is crucial for successful enzymatic action, based on the excellent ligand properties of catechols for iron.

Therefore, the specificity of catechol oxidase towards its substrates is strongly influenced by the ability of the substrate to bind in a particular orientation to the iron center, the interactions with amino acid residues within the active site, and the overall fit within the enzyme's substrate-binding cavity.

the answer is C)  Each of the organs is made from individual cells.

The right answer is A. Some carry out photosynthesis...

The sea slug, Elysia chlorotica, is the first discovered animal able to use photosynthesis to produce energy. This photosynthesis is performed by the chloroplasts of its main food source, the seaweed Vaucheria litorea. They are sequestered by the digestive epithelium of the slug for several months according to a phenomenon of kleptoplasty, continuing their function of carrying out photosynthesis.  

However, the chloroplasts of Vaucheria litorea have transferred a large part of their genes required for photosynthesis to the nucleus of the cells of this alga during evolution. Photosynthesis is nevertheless maintained in the sea slug thanks to the transfer of a gene necessary for photosynthesis from the kernel of the seaweed to the genotype of the slug.

Answer:

Rosalind Franklin Is famous for discover the size and shape(double helix)  of DNA.

Explanation:

Rosalind Franklin studied the x-ray diffraction in the DNA and the diffraction pattern, she captured a DNA imagen.  With this studies, she interpreted that DNA had a helical structure, DNA molecules were cylindrical and about 2 nm in diameter.

Her research gave ideas about DNA´s bonds to Watson and Crick.

Oxygen unloading occurs at the tissues. This process causes a decrease in the oxygen partial pressure of the blood leaving this region.

In tissues, where oxygen is needed for cellular respiration, oxygen unloading occurs from hemoglobin molecules in red blood cells. As oxygen is delivered to the tissues, the partial pressure of oxygen in the blood decreases.

This decrease in oxygen partial pressure facilitates the release of oxygen from hemoglobin, allowing it to diffuse into the surrounding cells for cellular respiration. Therefore, oxygen unloading at the tissues results in a decrease in the oxygen partial pressure of the blood leaving this region.

Using the GTPAL system, the woman's reproductive history would be represented as 3-1-0-1-0: 3 pregnancies in total, 1 term birth that resulted in a stillborn, 0 preterm births, 1 abortion (miscarriage), and 0 living children.

The system used to describe a woman's reproductive history is called the GTPAL system. The acronym stands for Gravidity, Term births, Preterm births, Abortions, and Living children. In this case, a woman who is 6 weeks pregnant, has had a previous spontaneous abortion at 14 weeks (considered a second-trimester miscarriage), and a stillbirth at 38 weeks (a Term birth, even though the child was not born alive), can be described using the GTPAL system as follows:

So, the GTPAL for this woman would be 3-1-0-1-0.

Mitochondria resembles the prokaryotic cells in structure and function. It is believed that mitochondria has been originated from the prokaryotic cells, upon their fusion with the eukaryotic cells.

Mitochondria is known as the Power house of the cell as it makes energy in the form of ATP by the process of cellular respiration. This energy is utilized by the body tissues in various processes.

Mitochondria is a semi-autonomous and double-membranous organelle. It has its own genetic material. This genetic material is similar to the genetic material present in the prokaryotic cells. The genetic material is present in the form of small circular DNA in both the prokaryotic cell and mitochondria.

Mitochondria are formed by the process of binary fission which is similar to the prokaryotic cells.

The best chokes to use for large birds such as turkeys are shotgun chokes that have an extra constriction and is extended. This is because a targeted shot is needed to be made on the bird to ensure that you hit it.

The full choke is considered the best shotgun choke for hunting large, slow birds like turkeys. This is because it constricts the pellets to a small area, improving accuracy and extending range, which is beneficial in hitting the target's vital areas.

When hunting a large, slow bird like a turkey, an ideal shotgun choke would be the full choke. This type of shotgun choke constricts the pellets to a small area, extending the range and improving accuracy. Unlike the cylinder (unchoked) that spreads the pellets quickly over a wider area, a full choke keeps the spread controlled and dense, which can be beneficial for turkey hunting as it increases the odds of hitting the target's vital areas. Because turkeys are typically larger and slower birds, the extra range and precision may prove more valuable compared to a cylinder or less constriction choke. In summary, the full choke would likely be the better option for this specific hunting scenario.
