1) Ecosystem that has recovered
2) Ecosystems are altered through the activities of humans.
3) Environmental impact caused by physical factors
4) Ecological niche without competition

Answers

Answer 1

This situation is an example of 'ecosystems are ALTERED through the activities of humans' (Option 2).

Human activities (i.e., anthropogenic activities) represent the main factor capable of affecting the homeostasis of the ecosystems.

Some human activities that negatively alter a natural ecosystem include deforestation for different purposes (e.g., urbanization, agriculture, etc), the introduction of non-native invasive species, pollution, etc.

These activities may trigger serious problems to the environment such as soil erosion, climate change, undrinkable water, etc.

In conclusion, this situation is an example of 'ecosystems are ALTERED through the activities of humans'.

In the pictures above, someone is holding ice cubes; it feels cold and they begin to
melt. Which of the following describes what is occurring?

Answers

Answer:

As shown in the pictures above, the ice is absorbing heat energy from the hand and the surroundings, which results in the melting of the ice- a process of change of state from solid to liquid. The hand feels cold .

Note: The question is incomplete as it is lacking some details.

Explanation:

Melting is a change of state process which involves the change from solid to the liquid state. Solids when they absorb heat, change to liquids at a temperature known as the melting point. This change of state occurs because the molecule of the substance acquires enough energy which to be able to overcome the intermolecular forces holding the ice crystals together, as a result, the molecules begin to melt.

In the picture,the melting of the ice held by the hand is because the ice absorbs heat from the hand as well as from the surroundings . As a result of this loss of heat from the hand, the hand feels cold after. The process of this heat transfer is by conduction whereby heat is conducted away from the hand in order to melt the ice which is contact with the hand.

Earth's early atmosphere was primarily composed of

hyrogen cyanide and carbon monoxide.

oxygen and carbon monoxide.

oxygen and water vapor.

carbon dioxide, water vapor and nitrogen.

Answers

Answer:

The correct answer is ''carbon dioxide, water vapor and nitrogen.''

Explanation:

About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.

Humans contribute to many changes of areas such as beaches, bays, wetlands, the sea floor, and coral reefs. How does the deliberate alteration of the ocean or terrestrial topography negatively impact marine ecosystems?

Answers

Answer:

For many years humans have been putting waste in oceans, wetlands, and lakes without thinking of the consequences. You know that saying “All roads lead to Rome” well most trash will end up in the ocean one way or another. There is a garbage patch in the ocean that is about 2x bigger than Texas. Many coral reefs are dying right now because of the oil and gas from the many boats that are traveling on the waters. A way to help solve these problems is using less or zero plastic. Plastic takes years to completely deteriorate. For example glass even though it's not plastic it still takes years to deteriorate. You know sea glass well that took years and years to get to that point when you find it at the beach.

Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fall into these categories, and provide an example of each type of interaction.

Answers

Answer:

Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.

Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.

Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.

Which two phrases describe the motion of all the outer planets?

no rotation, slow revolution
fast rotation, slow revolution
north-to-south rotation, slow revolution
no rotation, opposite revolution

Answers

Answer:

B. Fast rotation, slow revolution.

The two phrases that describe the motion of all the outer planets are fast rotation and slow revolution. Therefore,the correct option is B.

Outer planets, such as Jupiter, Saturn, Uranus, and Neptune, have relatively fast rotational speeds, meaning they spin on their axis more rapidly compared to the inner planets like Earth and Mars.

However, their revolution around the Sun is slower, as they are farther from the Sun and require more time to complete one orbit.

All outer planets have a slower revolution around the Sun compared to the inner planets. This is because their larger orbital paths result in longer orbital periods.

The niche of an organism within an ecosystem defines how the organism responds and reacts to the distribution and abundance of these factors, and in turn how it alters the factors.

What are the example of niche?

Example of niche includes when resources are abundant, a population grows, although by growing, the population although by growing, the population provides more resources for predators.

There are two major types of ecological niches namely fundamental niches and realized niches. Fundamental niche is the entire set of conditions under which an animal (population, species) can survive and reproduce itself. Realized niche is the set of conditions actually used by given animal  species), after interactions with other species (predation and especially competition) have been taken into account.

How does waste removal in a fetus differ from waste removal after birth?


A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.


B) Fetal waste is removed through the rectum; infant waste is removed through the chorion.


C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.


D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.

Answers

Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.

Explanation:

A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

Why do you think Europeans—and especially the English—are most affected by asthma?

Answers

Answer: Asthma is one of the most frequent chronic conditions in Europe, affecting more than 30 million Europeans – a number that is still growing.

"At some stage in the future almost half of the population may suffer from an allergic disease and asthma will be a considerable proportion of this," said Nikolaos Papadopoulos, professor of allergy and pediatric allergy at the University of Athens, in an interview. He added that it is also a global phenomenon.

Asthma is a chronic disease of the airways that makes breathing difficult. An asthma attack inflames and narrows the airways that carry oxygen to the lungs, leading to coughing, wheezing, shortness of breath, and chest tightness. Its prevalence has been linked to industrial development.
