Answer:
The statistics given has shown that night-migrating birds are driven by autonomous circadian clocks which is made possible by sunset cues. This timekeeping that is the autonomous circadian clocks system is probably the key factor in the overall control of nocturnal songbird migration.
Answer:White blood cells, also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system.
Explanation:
Based on the data provided, Anthony will be safe because Anthony's ladder will make a 75. 522 degree angle.
<h3>What is the height of the wall?</h3>
The height of the wall is determined using trigonometric ratios.
Since the ladder must be within 1 degree of 76 degrees to be safe, we assume the maximum angle to be 77°.
Length of the ladder = 10 m
The ladder, the wall of building and the floor form a right-angled triangle.
Height of wall = 10 × sin 77°
Height of wall = 9.74 m
If Anthony places the ladder 2. 5 feet from the base of the building, angle A, it will make with the floor is calculatedas follows:
Cos A = 2.5/10
Cos A = 0.25
A = 75.522°
Therefore, Anthony will be safe because Anthony's ladder will make a 75. 522 degree angle.

the daffodil is virtually synonymous with spring. Though their botanic name is narcissus, daffodils are sometimes called jonquils, and in England, because of their long association with Lent, they're known as the "Lent Lily." Lore connecting the daffodil to not only a sign of winter's end but a lucky emblem of future prosperity is found throughout the world. In Wales, it's said if you spot the first daffodil of the season, your next 12 months will be filled with wealth, and Chinese legend has it that if a daffodil bulb is forced to bloom during the New Year, it will bring good luck to your home.
