Suppose a drought kills only the smallest individuals in an initially diverse population of wolves. What type of selection is this?

Answers

Answer 1
This seems to be directional selection, in which the bell curve of wolves shifts to the right, away from the smallest inviduals in the population.

How could a change in the carbon cycle lead to a change in the water cycle? (Give me an example of an increase in one process leading to an increase or decrease in the process of the other cycle)

Answers

Answer:

Higher rates of carbon fixation lead to increased respiration, energy production and CO2 + H2O excretion.  

Explanation:

Inorganic carbon is fixed into high-energy polysaccharides by producers during photosynthesis and used by consumers in respiration to produce fuel, where it is produced as a waste product, along with water.

In photsynthesis...

 6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2 Carbon Dioxide + Water + Light       Glucose + Oxygen

In respiration..

.C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP glucose+ oxygen →  carbon dioxide+ water+ energy

Thus, changes in photosynthesis affect the ability of other organisms to respire and produce water. More fixation directly leads to increased respiration, production of ATP, and CO2 + H2O excretion.

Which of the following kinds of organisms do photosynthesis? Select all that apply.

Answers

Answer:

Plants, algae, cyanobacteria, and etc.

Explanation:

"Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth."

Plants, Algae, and some bacteria kinds of organisms do photosynthesis. So, the correct options are A, D and F.

What is Photosynthesis?

The word “photosynthesis” is derived from the two words photo means “light” and synthesis means, “combining together.” which means “combining together with the help of light.”

Photosynthesis is defined as the process by which light energy is converted into chemical energy, which is then used to fuel cellular activities where chemical energy is stored in the form of sugars. Which are made of water and carbon dioxide.

Photosynthesis can also applies to other organisms besides green plants such as several prokaryotes such as cyanobacteria, purple bacteria and green sulfur bacteria.

Thus, Plants, Algae, and some bacteria kinds of organisms do photosynthesis. So, the correct options are A, D and F.

Flat terrain/same moisture

Explanation:

Ive done a test that had this question and got it right.

The two conditions you need for air mass formation are flat terrain and same moisture. The correct option is B.

What is air mass formation?

It is Known as source regions, air masses form over large surfaces with uniform temperatures and humidity.

Low wind speeds allow air to remain stationary for long enough to absorb the characteristics of the source region, such as heat or cold.

When the atmosphere comes into contact with a large, relatively uniform land or sea surface for a long enough period of time, the temperature and moisture properties of that surface are acquired. The major air masses on Earth originate in polar or subtropical latitudes.

Air masses form over large surfaces with uniform temperatures and humidity, which are referred to as source regions, as well as flat terrain and the same moisture.

Thus, the correct option is B.

Blending inheritance is an outdated theory about inheritance that is no longer accepted.

We now know, thanks to Mendel's work on inheritance, that the inheritance of characteristics are not so simple!

Many bacteria and fungi are important in the environment because they recycle nutrients, making them available for other organisms.

DECOMPOSERS:

Based on their role in the recycling of energy and nutrients in the environment, living organisms can be grouped as either producers, consumers or decomposers.

Producers are organisms capable of synthesizing food on their own either by using sunlight (photosynthesis) or chemicals (chemosynthesis). They create the energy that is transferred in an ecosystem. Examples are green plants, algae etc. Consumers are organisms that depend on other organisms for their energy source or nutrients. Example include animals etc. Decomposers are organisms that degrade or breakdown dead organic matter, hence, returning nutrients to the soil to make them available for other organisms. Examples are some Bacteria, Fungi etc.

Answers

Answer:

Among others, two adaptations might be

Avoiding corporal heat lossIncreasing oxygen absorption  

Explanation:

Up in the mountains, there is low oxygen, food is scarce, and adverse meteorological conditions. Animals and plants need to develop different strategies to survive. These adaptations involve not only physical and physiological changes but also behavioral changes. To mention a few adaptations, we can name:

Avoiding heat loss. Temperature tends to be very low at highs, so, to avoid heat loss, animals develop shorter legs, tails, and ears. By doing this they reduce the area or surface of heat loss and also avoid getting frozen. In mammals, the coat is also very important. A thick coat helps them maintain a constant body temperature and keep warm. Some amphibians might also develop a thicker skin as they can not regulate their temperature, and it also helps them not to dehydrate. Camouflage: Coat is also helpful in camouflaging. Mammals´ hair color depends on their environment. Some animals, such as hares, can also change their fur color depending on the season. During snow seasons they turn white, and during the warmer season, they turn yellow or brown. Size and metabolism: Small mammals lose heat very fast, so they need to keep active and feeding most of the time. They have an elevated metabolism to keep warm. On the contrary, big animals, such as bears, need to hibernate to reduce their metabolism and get to survive, otherwise, they would need many reserves to cover their energetic requirements. Oxygen absorption: Some animals have adapted to the lack of oxygen by increasing their heart and lungs capacity as well as their capability to absorbing more oxygen from the blood.
