The process of activating photoreceptors by altering the photopigments is known as PHOTOTRANSDUCTION. It involves the mechanism by which light can be converted into electrical signals.

Phototransduction refers to the mechanism by which light can be converted into electrical signals.

Visual phototransduction occurs in the part of the eye known as the retina, in specific cells called photoreceptors and ganglion cells.

Photoreceptor cells include rod cells and cone cells, which are sensitive to light.

Which statement about US greenhouse gas emissions is supported by the bar graph? Emissions decreased every year between 2005 and 2014. Emissions increased substantially between 2005 and 2014. After peaking in 2007, emissions dropped every year through 2014. After peaking in 2007, emissions went up and down through 2014.

Answers

Countries often have records of gas emissions in their county. The statement about US greenhouse gas emissions is supported by the bar graph is that after peaking in 2007, emissions went up and down through 2014.

Greenhouse gas emissions often takes place due to the activities of human. These activities acts as a catalyst to powerup the greenhouse effect, causing climate changes.

Recorded data of gas emissions has shown that after it peaked in 2007, reduction is said to be of averaged 1.3% per year but the data of U.S. energy-related CO2 emissions in 2019 shows that it was 1.8% greater than in 1990.

Identify two specific populations that most likely increased in number after the mountain lion population decreased. Explain why.

Answers

Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.  

----------------------------

The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

The first link corresponds to a producer organism -autotroph-.  

The following links are the consumers -heterotrophs-: herbivores and carnivores.

The last links are the decomposers that degrade organic matter from dead organisms.  

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

According to the provided trophic web, puma feeds on deer and rabbit.

Since puma was killed, their population size sharply decreased.

This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.

In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.

The number of individuals of each species increased, and the amount of food consumed increased too.

This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.

So, cascade effects would be as follows,

1) The decreased in the puma population size caused an increase in the deer and rabbit population size.

2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.

3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and  rabbits for food.

The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

In deserts there’s a strong environmental pressure to conserve water. How did cactuses evolve to meet this pressure?

Answers

Answer:

Cacti evolved in the way that they are able to hold watter within themselves and their cells.

Explanation:

Cactuses have evolved in such a way that their roots and leaves hold water as long as possible. This gives the capability of cacti to meet this environmental pressure in order to conserve water.

What are the special adaptations of the cactus?

Under desert climates, cacti have various numerous unique adaptations in order to facilitate their survival in the same habitat. It includes its roots, leaves as well as stems that enable it to thrive in desert environments.

These adaptations include: Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water.

Therefore, cactuses have evolved in such a way that their roots and leaves hold water as long as possible.

The term that would best define the fish added to the pond is INTRODUCED species. These species may be harmful to native species.

Introduced species are exotic species which has arrived there by human activity, which may be harmful to native species.

Introduced species may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.​

Answers

According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.

Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as

Volcanism The rock cycle The wind The rainfall Among other

Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.

This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.

Amount of salt

Amount of water

Temperature of the water

Number of plants in the water

Answers

Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.

The independent variable is this case is the amount of salt.

In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.  An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect. Therefore, with this case, the amount of salt would cause a decrease in the number of plants. While the effect of increasing the amount of salt would be seen in the number of plants.
