WHY does SUCCESSION OCCUR?
Answer:
Why does ecological succession occur? Every species has a set of environmental conditions under which it will grow and reproduce most optimally. Ecological succession may also occur when the conditions of an environment suddenly and drastically change.
Explain the trend that is related to biodiversity levels of ecosystems
I need it ASAP
Answer:
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

2. Below is an image of 2 imaginary organisms. Organism A lived hundreds of years ago while organism B is
alive today. Explain how organism A evolved into organism B, including what environmental pressure (i.e.
predator, habitat, competition, etc) you believe guidede natural selection process that worked on this
species.
0-Organism
A
Organism-B
Answer: Click or tap here to enter text.
Answer:
The new modification in Organism B is the tail.
Explanation:
This might indicate that the organism has to sprint in order to catch prey or to get away from predators. The organism is most likely not a prey, since it has sharp teeth, making it a carnivore. The tail helps in stabilizing the animal while running. The animal might have new threats that have developed over the years (like humans).
Helicobacter pylori, the bacterium responsible for gastric ulcers, can survive in the stomach (where the pH is as low as 1.5) in part because it synthesizes large amounts of the enzyme urease. (a) Write the reaction for urea hydrolysis by urease. (b) Explain why this reaction could help establish a more hospitable environment for H. pylori, which tolerates acid but prefers to grow at near-neutral pH.
Answer:
a) (NH₂)₂CO + H₂O ---> CO₂ + 2NH₃
b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a base by accepting the hydrogen ions present in the acidic environment of the stomach. This reactions serves to neutralize stomach acid in order to create a suitable pH environment that the bacterium requires to survive and colonize.
Explanation:
a) Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The equation of the reaction is shown below:
(NH₂)₂CO + H₂O ---> CO₂ + 2NH₃
b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a base by accepting the hydrogen ions present in the acidic environment of the stomach. This reactions serves to neutralize stomach acid in order to create a suitable pH environment that the bacterium requires to survive and colonize.
The reaction of ammonia with hygrogen ions from HCl is shown below:
NH₃⁺ + H⁺ ----> NH₄⁺
Therefore, the continuous activity of the enzyme urease, helps to establish a more hospitable environment for Helicobacter pylori

Where is ATP produced?
Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenate into a pellet in the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains

This pellet most likely contains
1. peroxisomes
2. mitochondria
3. lysosome
4. Golgi complex
5. endoplasmic reticulum
Answer:
2. Mitochondria
Explanation:
Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.
The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.
Mitochondria are more grouped in areas or tissues with higher energetical requirements.
As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.
By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.
Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.
Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.
Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.
The Krebs cycle produces a four-carbon molecule known as succinate.
Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.
Finally, oxygen is consumed during oxidative phosphorylation.
In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

3. What is the difference between cotyledons in dicot seeds and the endosperm in monocot seeds?
Explanation:
Monocots contain a single cotyledon in their seed and dicots contain two cotyledons. The nutrients in the endosperm of dicots is absorbed by the two cotyledons. Therefore, a tiny endosperm is found inside the dicot seed. However, the main difference between cotyledon and endosperm is in their function during seedling.

D. many students pass from a crowded room into an empty hallway
Diffusion can be described as the movement of molecules from a region of higher concentration to a region of lower concentration.
A model of diffusion could be many students pass from a crowded room into an empty hallway (option D).
A model is used to describe/illustrate a particular event or situation. In this case, the crowded room is the region of higher concentration. And the empty hallway is the region of lower concentration. The molecules refer to the students. And their movement from the crowded room to the empty hallway refers to diffusion.Learn more about diffusion: https://brainly.com/question/2135861

1.Their genotype is either AA or AO
2.blood type B could have a genotype of either BB or BO
type AB or type O is more informative.

A cell with a diploid number of 2n = 8 undergoes mitosis. How many
chromosomes will EACH new cell have?
Answer:
8
Explanation:
Mitosis, a type of cellular division, involves the division into two daughter cells that are genetically identical to the parent cell. They are genetically identical in the sense that the daughter cells contain the exact same DNA sequence as the parent cell and also, the chromosome number does not change.
In this case, a cell is said to have a diploid number (2n) of 8 chromosomes. It will therefore, undergo mitosis to produce two daughter cells with 8 chromosomes each. For this reason, mitosis is called MULTIPLICATION DIVISION.

Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.
Answer:
The correct answer is -
1) point mutation
2) deletion
3) inversion
4) frameshift mutation.
Explanation:
Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.
Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.
When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.
If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.
