Answer:

He human eye is poorly suited to night vision, suffering impairments in seeing the environment in low light situations.

Explanation:

In the eyes are the rods, the neurons responsible for the night vision. In total darkness, there is a need for at least 45 minutes to get the best vision, because the human eye is poorly adapted to night vision and is deficient in seeing in the dark. In the retina of the human eye there are two distinct regions, one responds by the central vision, the macula, and another peripheral vision.

Inside the macula, a region called fovea consists only of cones, which are neurons responsible for maximum vision. The cones do not work in low light conditions. However, around the fovea, there is a mixture of conese rods. This blend allows an intermediate view, which guarantees the ability to see in the penumbra.

The human eye is grief in damage of in-depth perception, color recognition, and peripheral vision. Judging speed and distance based on visual evidence is also more difficult in the dark.  In addition, the darkness of night, and even the dimness of dusk and dawn.

In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.

Why is the human brain NOT considered to be a living organism? A) It is not made of cells B) It cannot complete photosynthesis C
Cerrena [4.2K]
My best guess would be c because b makes no since we as humans do not have photosynthesis and are considered living organisims, d is also wrong because the brain requires oxygen, and its not a because the brain is made of cells.

What are three ways body systems work together to maintain homeostasis?
mafiozo [28]

Answer:

Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.

For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water. If the water level gets too low, more concentrated urine is produced so that water is conserved. The digestive system also plays a role with variable water absorption. Water can be lost through the integumentary and respiratory systems, but that loss is not directly involved in maintaining body fluids and is usually associated with other homeostatic mechanisms.

Similarly, the cardiovascular, integumentary, respiratory, and muscular systems work together to help the body maintain a stable internal temperature. If body temperature rises, blood vessels in the skin dilate, allowing more blood to flow near the skin’s surface. This allows heat to dissipate through the skin and into the surrounding air. The skin may also produce sweat if the body gets too hot; when the sweat evaporates, it helps to cool the body. Rapid breathing can also help the body eliminate excess heat. Together, these responses to increased body temperature explain why you sweat, pant, and become red in the face when you exercise hard. (Heavy breathing during exercise is also one way the body gets more oxygen to your muscles, and gets rid of the extra carbon dioxide produced by the muscles.)
