Answer:
The correct answer is - producers.
Explanation:
Producers are organisms that are capable of making their food and energy on their own with the help of light energy get from the sunlight. These are the base of any ecosystem due to the fact that all the organisms depend directly or indirectly on the producers for food and energy.
So, if all the sunlight is blocked from reaching the earth's surface producers will be affected first in terms of ecosystem and trophic level.
Thus, the correct answer is - producers.
A student is given a list of traits and is asked to organize them in a Venn diagram as shown below.
Which traits should the student put in section II (Both)?
1 a scar and blood type
2 tiger's stripes and wolf's social status
3 musical talent and wolf's social status
4 musical talent and skin color
Answer: The correct answer is option B) a scar and wolf's social status.
The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.

experiment yeast fermentation ，how do the results show that fermentation has taken place in boiling tubeA？
Answer:
The bubble formation is stopped.
Explanation:
The results show that fermentation has taken place in boiling tube A when the bubble formation is stopped which is the indication that the fermentation process is completed. If the bubbles are continue to produce from the solution this means that the fermentation process is taking place and not yet completed. These bubbles are formed due to production of carbondioxide in the reaction which provides information about fermentation process.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Explanation:
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation.
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation. Thus, option A is correct.
What is transpiration?Transpiration has been known as the method by which water vapor would lost via the stomata of the plants. When the weather has very hot, the plant's loss of water vapor cools it down, and water from the stem and the roots moves upwards or has been started to pull into the leaves.
The direct impact of the transpiration has that it would regulates plant temperature and the provides water for the photosynthesis. It also transports the nutrients and the sugars through the plant's vascular tissues.Evaporation and the transpiration are the two processes that would allow water to enter the atmosphere.
Therefore, Evaporation has been known as a way of vaporization that use to occurs on the surface of the liquid as it has the transitions from the liquid phase to the gas phase.
