We support each of the following correct statements with appropriate justification, indicating why or how each statement is correct.
<h3>3. A radiograph of a horse's frontal fetlock joint is called a dorsopalmar (PD) view.</h3>
Dorsopalmar (PD) view The horse's frontal fetlock joint demonstrates dislocation of the antebrachiocarpal joint with soft tissue swelling around the carpal joint
<h3>5. When performing surgery on the digestive system, we must ensure that the suture is well closed. </h3>
Yes. Endoscopic suturing is a procedure performed 100% by endoscopy, a procedure that inserts a flexible tube through the patient's oral cavity and reaches the structures of the digestive system. It is a non-invasive, safe process that does not require any cutting.
<h3>6. Oblique positions are sometimes used in radiographs.</h3>
Yes. Right and Left Anterior Oblique Positions (RAO and LAO) These terms refer to oblique positions in which the right or left anterior side of the body is close to the RI, and can be in an upright or recumbent position.

Answer:
1. Bryofita
2. vascular plants
3. Seed vascular plants (gymnosperms)
4. Angiosperms
Explanation:
1. Bryofita
Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.
2. Vascular plants
Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.
3. Seed vascular plants (gymnosperms)
Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.
4. Angiosperms
About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure
complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms

I have attached lac operon model having 4 genes. See attachment for better understanding.
Answer:
The Lac operon is controlled by two signals.
Initiation
Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.
Lactose absent (Repression)
When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.
Lactose present (Transcription)
Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.
Glucose absent (Repression)
When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.
Glucose present (Transcription)
LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.
The answer to this question would be: antibody
There are 4 types of hypersensitivity. In type II hypersensitivity, the reaction depends on the antibody. Some of the body cells surfaces were similar to the pathogens that the white blood cells trying to fight. This causing the body also attack the body cells too. It is also called cytotoxic hypersensitivity.
In mismatch transfusion, the receiver recognizes transfused blood cell as foreign material so it was making antibody to fight it.
The correct answer is neutrons, they do not carry an electronic charge.
Hope this helps.
