The answer is dusk and dawn.
Crepuscular animals are active during twilight (latin crepusculum). Twilight is a period after dawn and before dusk, so crepuscular animals want to avoid dusk and dawn. Animals' activity in different periods during the day depends on temperature or other biotic factors. It also depends on predators' activities or local competition.
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:
4. B cells become activated by interacting with helper T cells.
1. B cells display antigens in MHC class II receptors on the cell surface.
2. Antibodies released by plasma cells bind to the antigen so they will be destroyed by other cells of the immune system.
3.B cells rearrange their DNA to create a unique B-cell receptor.
5. B cells undergo clonal expansion.
6. B cells digest antigens that bind to the antibodies on their surface.
Explanation:
B-cells get activated by interacting with helper T cells when they bind to the antigen to receptors i.e (MHC class II receptors on the cell surface) on the surface of the cell. Series of activities such as release by plasma cells which cause rearrangement of B cells causes the cell to divide and proliferate. The process through which daughter cells arise from a parent cell called clonal expansion.

Answer:
Manuel Roxas, (born Jan. 1, 1892, Capiz, Phil.—died April 15, 1948, Clark Field, Pampanga), political leader and first president (1946–48) of the independent Republic of the Philippines.
After studying law at the University of the Philippines, near Manila, Roxas began his political career in 1917 as a member of the municipal council of Capiz (renamed Roxas in 1949). He was governor of the province of Capiz in 1919–21 and was then elected to the Philippine House of Representatives, subsequently serving as Speaker of the House and a member of the Council of State. In 1923 he and Manuel Quezon, the president of the Senate, resigned in protest from the Council of State when the U.S. governor-general (Leonard Wood) began vetoing bills passed by the Philippine legislature. In 1932 Roxas and Sergio Osmeña, the Nacionalista Party leader, led the Philippine Independence Mission to Washington, D.C., where they influenced the passage of the Hare-Hawes-Cutting Act. Roxas was later opposed by Quezon, who held that the act compromised future Philippine independence; the Nacionalista Party was split between them on this issue.
