A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.

Answers

Answer:

A drought is a long period of abnormally low precipitation. Suppose a drought occurred in Yellowstone National Park from 1916 to 1917. Predict how a graph line would appear for this time period. Explain your prediction in terms of the effect on resource availability.

Explanation: The graph line would have a downward trend because the amount of bison would start to decrease. Droughts heavily impact grassland ecosystems. A drought would increase the risk of a wildfire starting causing the bison to lose their habitat. The drought would also result in reduced plant growth. Therefore the bison would die off either because they were impacted by a wildfire, because they don’t have grass to eat etc.

During cellular respiration, cells convert oxygen and glucose into carbon dioxide, water, and energy. How is this process related to that of photosynthesis?

A. The products of photosynthesis are the reactants of cellular respiration.

B. In photosynthesis, cells use ATP to convert insulin into glucose and carbon dioxide
C. In photosynthesis, oxygen is inhaled, and carbon dioxide and water are exhaled.

D. Both photosynthesis and cellular respiration occur in a cell's mitochondria.

Answers

A. the products of photosynthesis are the reactants of cellular respiration

Carbon in the atmosphere (CO2)

Carbon in plants and animals

It must move through at least 5 different living things (plants/animals) - be sure that the plants/animals would actually interact with each other in nature (ex no african lions eating arctic foxes) this may require a bit of research.

Extra credit - show it becoming fossil fuels and the fossil fuels being burned to release CO2 back into the atmosphere.

In plants/animals- either how its stored in the plant/animal then the plant/animal being eaten or the steps of cellular respiration

In plants- the steps of photosynthesis (how it goes from being CO2 to glucose)

Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other

Answers

Answer:

Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

Answers

An ecosystem is defined as the geographical region, in which plants, organisms, and animals with abiotic factors like weather, water, and landscape. The ecosystem that changes over time is known as ecological succession.

The correct answer is:

Option C. The ecosystem will undergo primary succession followed by secondary succession.

Ecological succession can be defined as:

1. Ecological succession refers to the change in the structure of the species in an ecological community over time.

2. The primary ecological succession begins in the lifeless region, such as the regions with no soil or incapable of sustaining life. In this, newly formed rock is colonized by living organisms for the first time.

3. The primary succession will be followed by the secondary succession, in which the organisms tend to re-habitat the area that has been destructed due to natural or human-made events.

Thus, in the given picture, the primary ecological succession is followed by the secondary ecological succession.

Animalia that consist of many cells with an organized nucleus, have two parents, and eat food.

What are the characteristics of Animalia?

Animal cells are the basic living unit of organisms in the kingdom Animalia. They are eukaryotic cells, which means they have a true nucleus and special structures called organelles that perform various tasks.​​​​​​​

All members of the Animalia are multicellular, and all are heterotrophs (meaning that their nutrition depends directly on or indirectly on other organisms). Most swallow food and digest it in an internal cavity. Animal cells lack the rigid cell walls characteristic of plant cells.
