Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia,

The correct responses include:

It provides insulation for the complex in winter.

It ensures passive cooling during summer months.

Fusionpolis is a building located in Singapore, featuring a facade of spine vegetation. This unique cover is well-regarded for providing heat insulation, which effectively maintains the building's temperature. The spines function as insulation during colder months, while their transpiration process assists in cooling during summer.

Answer:

1. A

5. A

Explanation:

Answer:

a)

Based on observations from the cell groups, the protein p16 seems to have no significant role in preventing fibroblasts from entering the cell cycle. This finding is illustrated in group 7, where the DNA replication rate is nearly as high as that in the 10% serum condition, despite the presence of p16 alone.

In other groups (3 to 6), any additional proteins have always resulted in reduced DNA replication compared to fibroblasts cultured in 10% serum.

b)

Groups 4 to 7 demonstrate a higher likelihood of containing cells that are dividing, as evidenced by their increased DNA replication rates relative to group 1, which has 0% serum. This group, having been cultured for 48 hours without serum (serum-starvation), halts division and transitions into the G0 phase of the cell cycle.

c)

This data is pivotal in identifying which proteins trigger cellular entry into the cycle. For healing post-injury, cellular division and repair are crucial, which can be stimulated by the appropriate protein. Additionally, it will clarify which proteins hinder cell cycle entry.

Answer:

TRUE

Explanation:

Green plants possess chlorophyll, a green pigment in their leaves. Chlorophyll can absorb the sunlight required for photosynthesis to occur. Photosynthesis refers to the process by which green plants produce food in the presence of light, water (H₂O), and carbon dioxide (CO₂), resulting in the release of glucose and oxygen (O₂) needed for the survival of all living beings.

The reaction that occurs during photosynthesis is illustrated below-

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This method converts light energy into chemical energy, which is stored in glucose molecules.

Consequently, the statement is TRUE.

There are 36 potential outcomes when rolling two casino dice, and out of these, six combinations yield a sum of 7: <span> 1-6, 2-5, 3-4, 4-3, 5-2, and 6-1. </span> Consequently, the likelihood of achieving that specific outcome among the 36 possible results is 6/36. Therefore, the probability of the total being seven is 6/36 = 16.667%
