Answer: Thymus gland

Explanation:

The thymus gland is an endocrine gland that is located in the upper part of the human chest. It is responsible for producing white blood cells. This gland is located near the airway.

The thymus gland produces several endocrine hormones like thymopoietin and thymulin.

The given condition is indicative of the mass of the thymus gland.

Difference between osmosis, diffusion and plasmolysis
pickupchik [31]
Osmosis is the movement of water particles from an area of high concentration of water particles to an area of low concentration of water particles across a semi permeable membrane

Diffusion is the movement of particles from an area of high concentration of particles to an area of low concentration of particles across a partially permeable membrane

Plasmolysis is the shrinking of the cytoplasm if a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution as the cell membrane would pull away from the cell wall

Deffense [45]

Answer:

Its false  

Amphicoelias altus (from the gr. "Hollow character on both high sides") is the only known species of the extinct genus. Titoniense, in what is now North America. Amphicoelias is present in stratigraphic zone 6 of the Morrison Formation

It was also similar in size to Diplodocus, about 25 meters long. Although most scientists have used this data to distinguish Amphicoelias and Diplodocus as separate genera, at least one has suggested that Amphicoelias is probably the largest synonym for Diplodocus.3 Amphicoelias altus, was named by paleontologist Edward Drinker Cope in December of 1877, although it was not published until 1878, for an incomplete skeleton consisting of two vertebrae, a pubis, the hip, and a femur, bone of the upper leg.4 Cope also named a second species, A. fragillimus

Humans are different from each other in many ways, including in their sizes, shapes, skin color, facial features, and handedness
strojnjashka [21]

Answer:

<em>The correct option is C) Humans from different locations can donate blood and organs to one another.</em>

Explanation:

Organisms belonging to the same species can interbreed and produce fertile offsprings. As humans all around the world can interbreed and produce fertile embryo hence all human beings belong to the same species. Also, the organs and blood of organisms from the same species can be transferred depending on the compatibility. It is less likely for the human body to reject a graft from other human being rather than another species. Although, xenotransplantation has been practiced in the laboratory by scientists but it has not produced any good results.

In the US, there are existing state laws to protect individuals from genetic discrimination in what areas? Select all that apply
bonufazy [111]

Answer:

In the United States there are existing state laws to protect people from genetic discrimination in areas such as insurance companies and workplaces.

Explanation:

Genetic discrimination is based on the possibility that an individual manifests a disability or inherited disease due to a genetic alteration.

In many cases, both workplaces and insurance companies require genetic testing before granting a job or an insurance policy.

A federal law - Genetic Information Nondiscrimination Act or GINA - protects people against this requirement of their future employers or any insurance company and guarantees, with certain exceptions, the possibility of obtaining a job or medical insurance.
