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

Answer:

There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles.

Explanation:

Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth's surface.

Answer:

Most likely a dog and a turtle.

Explanation:

A Dog and a Turtle organisms do you think might be more closely related to each other, So, the correct option is A.

An organism is defined as any living system which functions as an individual unit where all living things are made up of cells. The concept of organism is based on the concept of the minimum functional unit of life.

Biological organisms are defined as living things capable of responding to stimuli, reproduction, development and homeostasis which are classified by taxonomy into specified groups such as multicellular animals, plants and fungi; or unicellular microorganisms such as protists, bacteria and archaea.

A Dog and a Turtle organisms do you think might be more closely related to each other as both have four legs and belongs to Phylum Chordata.

So, the correct option is A.

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.

Complete question:

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at 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

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.

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).

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.

Antibiotics are added to the animal feed or drinking water of cattle, hogs, poultry and other food-producing animals to help them gain weight faster or use less food to gain weight.

Because all uses of antimicrobial drugs, animals contribute to the development of antimicrobial resistance, it is important to use these drugs only when medically necessary.

the production (e.g. growth enhancement) purposes as well as for the treatment, control or prevention of animal diseases. Even today, it is not entirely understood how these drugs make animals grow faster. The drugs are primarily added to feed, although they are sometimes added to the animals’ drinking water.
