The kingdom is Animals.
The genus is Haliaeetus.
The species is leucocephalus are the statements which Julio can make about the bald eagle.
The option C is the correct answer.
Explanation:
Given that Bald eagle has binomial name as Haliaeetus leucocephalus.
Modern classification of binomial nomenclature is given by Carl Linnaeus.
From the modern system of classification the sequence is as kingdom, phylum, class, order, family, genus and species. The classification of bald eagle is:
Kingdom - Animalia
Phylum - chordata
class - Aves
Order- Accipitriformes
family - Accipitridae
Genus - Haliaeetus
species - leucocephalus.
The two word name of the species having genus first followed by species is binomial nomenclature which Julio has used for bald eagle as Haliaeetus leucocephalus.
Answer:
(d). B-cells.
Explanation:
Adaptive immunity can be described as immunity which develops in response to exposure to a pathogen (or foreign molecule). throughout the life. It is divided into two types, humoral immunity and cell-mediated immunity.
Humoral immunity is mediated by B cells that secrete antibodies against particular antigens. These antibodies recognize and neutralize the antigens and activate cell-mediated immunity, which is mediated by T cells.
Thus, the correct answer is option (d).
Answer:
Simple cuboidal epithelia are found in areas that stretch.
Explanation:
The simple cuboidal epithelium consists of a single layer of cuboid cells with a centrally located nucleus. The cells of this epithelial tissue are mostly involved in secretion and absorption and therefore, are found in the lining of ovaries, lining of kidney tubules and gland ducts.
Transitional epithelium is like a stratified cuboidal epithelium when not stretched. Its cells become flatter when the tissue is stretched. It has multiple cell layers and elasticity and therefore, is found in the lining of the urinary bladder and parts of ureter and urethra to allow stretching of these organs.
