A population of peppered moths is monitored over several generations. It is observed that the number of white moths compared to

the number of black moths changes with each successive generation. This means that the population cannot be at equilibrium and the population is therefore evolving.

Answer:

True

Explanation:

Evolution is the change in the characteristics of a population over generations. This is caused by nature selecting out some disadvantageous traits and preserving advantageous traits over successive generations through natural selection pressures. In this case, the white moth is at a disadvantage in the environment compared to the black moth. The allele for white color is, therefore, ‘weeded out’ over time.

Alona [7]

Answer:

<u>Chloroplast</u>

The chloroplast is where photosynthesis occurs in plant cells. During photosynthesis, sunlight energy, carbon dioxide, and water are converted into simple sugars (glucose). These simple sugars are cell's version of food.

<u>Mitochondria</u>

The mitochondria is where cellular respiration occurs. During the process of cellular respiration, glucose, which is produced through photosynthesis in the chloroplasts, is broken down into cellular energy that can be used by the cell.

- Both chloroplasts and mitochondria are organelles that generate metabolic energy.

An element has a half-life of 30 years. If you start with 10g of this element, how many grams of this element would remain after
drek231 [11]

After two half-lives or 60 years, 7.5 g of the element will be left.

<u>Explanation:</u>

<u>Half-life:</u>

  • In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
  • In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
  • After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
  • And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
  • After two half-lives or 60 years, 7.5 g of the element will be left.

The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.
DanielleElmas [232]

Answer:

The statement that is true about red currents in the thermohaline circulation is that  water in the red currents contain less salt (option A).

Explanation:

Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.

On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:

  • <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
  • <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>

The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.

Which of these actions is the best way for an individual to conserve water?
BigorU [14]

Answer: B. Take short showers instead of baths.

Explanation:

The water is the most important non-living environmental factor which is the main requirement for survival of every living being. Even though water is a renewable resource which can be replenish by the mode of water cycling in nature but with the increase in the global population the demand of freshwater has increased. Also with the increase in the causes and sources of water pollution the levels of freshwater sources are decreasing. Therefore, the issues of water conservation should be taken into consideration.

According to the given situation, if an individual needs to conserve water, take short showers instead of baths is the correct option because of the fact that short showers will prevents the wastage of large amount of water which could be wasted while taking baths.
