Answer:

Primary succession is the beginning step of ecological succession after an extreme , which usually occurs in an environment devoid of vegetation.

In second at succession, an area that was previously occupied by living things is disturbed,then re colonized following the disturbance.

climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state.

Cholecystokinin is hormone that is secreted in response to pancreatic enzymes.

Cholecystokinin is a peptide hormone that is secreted by the duodenal mucosal of enteroendocrine cells as a result of stimulation of food by chemical substances. This hormone help to activate pancreatic enzyme secretion when it stimulate some cells of vagal afferents.

Therefore, Cholecystokinin is hormone that is secreted in response to pancreatic enzymes.

Answer:

Explanation:

Theorizing the chemistry of the calcification process, however, Biosphere 2 collaborators such as Marlin Atkinson of the University of Hawaii and Chris Langdon, Taro Takahashi, and Wallace Broecker of Lamont-Doherty Earth Observatory hypothesized that rising atmospheric CO 2 levels, which increase the partial pressure of CO 2 dissolved in seawater, might also exert important effects by changing the equilibrium of calcium carbonate and bicarbonate ions, making calcium carbonate less available to the living coral organisms.

Answer:

With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.

Answer:

Increasing the trophic level always results in a decrease in organisms (biomass) and energy because When energy decreases, it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Only a fraction of the energy available at one trophic level is transferred to the next trophic level. Typically the numbers and biomass of organisms decrease as one ascends the food chain.

The primary reservoir for calcium that is released during excitation-contraction coupling in a skeletal muscle fiber is sarcoplasmic reticulum.

The sarcoplasmic reticulum is responsible for storeing calcium ions which it releases when a muscle cell is stimulated.

So we can conclude that the primary reservoir for calcium that is released during excitation-contraction coupling in a skeletal muscle fiber is sarcoplasmic reticulum.

Explanation:

In sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.

Hybridization is a mixing of atomic orbitals which are of different shapes and have nearly same energy with give rise to same number of hybrid orbitals of same shape, equal energy and orientation so that there is minimum repulsion between these hybridize orbitals.

This is useful to explain the covalent bonds in organic molecules.

There are 3 types of hybridization which are based on the mixing of the orbitals

1. [tex]SP^{3}[/tex] hybridization- In this type of hybridization one s orbital and 3p orbital which are of same shell of atom mix together to form new orbital.

2. [tex]SP^{2}[/tex] hybridization - In this type of hybridization one s orbital and 2p orbitals mix together to form equivalent orbitals.

3. [tex]SP[/tex] hybridization - When 1 s and 1 p orbital goes in the process  and mix together to form new orbital. The molecules who possess sp hybridization have linear shift with an angle of 180 degree.

Thus, in sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.

We can confirm that fossils are used in order to study organisms that once lived.

Fossils are a term we use to refer to the remains of prehistoric organisms. This means organisms that lived a very long time ago. Fossils are notoriously rare and difficult to find and can come in varying stages of preservation. These fossils provide valuable information as to the species of organisms that existed many centuries ago.

Therefore, we can confirm that fossils are used in order to study organisms that once lived.

Answer:

survival of the fittest

Some die, some survive. Those that survive to reproduce pass along their genes. Some survive by good luck. Others survive because they happen to have some quality that gives them a better chance to tolerate the environmental changes. Assuming those qualities are heritable, they’ll become more common in the genes of the surviving population. Eventually they’ll predominate. The population will have adapted to the changes.

With the exception of very primitive organisms, living animals have various senses including those familiar to us as sight, sound, touch, taste, and smell. Certain organisms have senses that we do not share. For instance, the class of snakes we call “pit vipers” have a specific organ that senses heat from prey animals, even in total darkness.

Bats use echolocation, bouncing high-pitched sound waves off of obstacles and prey alike. So do dolphins.

Many insects have the ability to smell only a few molecules of pheromones from potential mate

I took the question differently than everyone else, but it sounded to me like the OP was asking for examples of HOW organisms adapt, not two organisms that adapted.

Adaptation often begins with environmental monitoring systems. Lets say antibiotics are taken by a patient and a small amount gets in the area of a pathogen who is testing its environment. The pathogen detects the threat and begins to construct a genomic edit that can counter it. Unfortunately for us, cells are still more skilled with biochemistry than humans.

If you mean like to adapt in an instant, we humans release adrenaline to overcome stress and it actually makes us more prone to overcome stress. Another example its σ32 is the heat shock sigma factor in Escherichia coli, which it helps the bacteria to survive in a “heat shock”.

When we look at evolution, we often look at bacteria or animals that aren't really related to us, like the dinosaurs and how they evolved into avian animals.

There are two examples in human history that are great for this question.

Humans

Yup. People have made adaptations to the environment. Well, at least the environment that we create for ourselves.

Milk contains lactose, which requires a special enzyme to break down. After a few months of age, babies lose this enzyme and become lactose intolerant. So why can we drink milk now?

(1) Antibiotic resistance

(2) Mitochondria losing unnecessary genes for symbiosis w/ eukaryotes

this is a miracle of evolution as we have read in our childhood about camels and about xerophytes(cactus) they got adapted to their environment but according to Darwin there is survival of the fittest which means there may be various types of a single species now under a harsh environment it may be that not all types of a single specie lives so they perish

There will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

The so-called incomplete dominance is the one in which the alleles are expressed in heterozygosity, however, they produce an intermediate phenotype, since none is totally dominant. In the case of complete dominance, the phenotype is equal between zygotes and heterozygotes.

With these information, we can conclude that there will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem

Most of the energy that enters an ecosystem comes from solar radiation. The producing organisms that carry out photosynthesis absorb solar energy and fix it in chemical energy. When consumers feed on producers, part of that energy goes to these organisms, which, by serving as food for other living beings, also pass on part of their energy to them. This, therefore, flows, in a unidirectional direction, passing from a lower level to a higher one.

With this information, we can conclude that a leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
