Answer:
Explanation:
Pulmonary circulation refers to a part of the circulatory system involve in carrying deoxygenated blood away from the right ventricle to the lungs and then carries oxygenated blood to the left atrium and ventricle of the heart.
Deoxygenated blood leave through the right ventricle by passing the pulmonary atrium. At the right atrium,the blood us pumped and move into the tricuspid valve into the right ventricle. The blood is then pumped from the right ventricle from the pulmonary artery. The pulmonary arteries carry deoxygenated blood into the lungs and here carbondioxide is removed and oxygen is use for respiration. Oxygenated blood is carried away from the lungs through the pulmonary veins which then return the blood to the left chamber of the heart completing the pulmonary cycle. Tye blood flow to the left atrium which is pumped to the left ventricle through mitral valve. From the left ventricle, the blood flow through the aorta through the aortic valve which distribute the blood to all part of the body and pulmonary circulation begins again.

given that cells can't store app for long periods of time, how do they store energy
Answer:
Given that cells can't store ATP for long periods of time, how do they store energy? Instead of storing ATP, cells tend to store energy as fats, oils, or starches. These are very large molecules and, as a result, do not have as great an effect on osmotic potential.

During photosynthesis and cellular respiration, plant cells carry out processes that involve both light energy and chemical energy. Sort each tile into the correct column. Light energy, Chemical energy. Released through cellular respiration, used to directly power photosynthesis, captured by chlorophyll, used to directly power cell growth
Answer:
Light Energy: used to power photosynthesis, captured by chlorophyll
Chemical energy: Released through cellular respiration, used to directly power cell growth
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions.
Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.They take sunlight and combine carbon dioxide (CO₂) and water (H₂O). They create glucose (C₆H₁₂O₆) and oxygen gas (O₂). By this process, plants change energy from the sun into glucose. The reverse of this process is cellular respiration.Thus, Light energy is used to directly power photosynthesis and Chemical energy is released through cellular respiration.

Which event occurs prior to speciation?
A) Different species share the same space.
B) A major change on earth takes place.
C) A population is divided.
D) Organisms of different populations join together.
Answer: C.
Explanation:
I hope this helps plz tell me if its wrong so i can fix it :)
The event that occurs prior to speciation is that a population is divided, which is Option C, as when a population is divided by a geographic barrier such as a mountain range, river, or sea, then this type of speciation takes place.
What is speciation?Speciation is the process by which a single ancestral species gives rise to two or more descendant species, and it occurs when populations of the ancestral species become separated and evolve independently, accumulating genetic differences over time by a physical or geographical barrier along with mutation, genetic drift, or natural selection that separates a population into two or more groups that are no longer able to interbreed leads to speciation.
Hence, the event that occurs prior to speciation is that a population is divided, which is Option C.

RNA interference
posttranslational silencing
RNA-induced silencing
methylation of CpG islands
position effect variegation
genomic imprinting
Answer:
RNA interference
post translational silencing
RNA-induced silencing
Explanation:
Viruses are the pathogenic living organisms which invade the host cells of plants, animals, humans, and of other organisms to produce their own genetic material and progeny viruses. The following are the methods using which the eukaryotic organisms can prevent themselves from infections.
1. RNA interference: In this viral RNA is cleaved by the use of complementary RNA sequence present in the genome of the host cell.
2. Post translational silencing: In this the gene products of viruses are silenced.
3. RNA induced silencing: It involves the inhibition of replication of RNA of virus by the host cell machinery.
A strain of bacteria possesses a temperature‑sensitive mutation in the gene that encodes the rho subunit. At high temperatures, rho is not functional. When these bacteria are raised at elevated temperatures, what would you expect to observe?
a. All RNA molecules are shorter than normal because the absence of functional rho would derail the transcription.
b. Transcription does not take place because mutant rho would interfere with the RNA polymerase binding to the template.
c. Some RNA molecules would be longer than normal because these RNA came from the gene with rho-dependent terminator.
d. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent.
e. All RNA molecules are longer than normal because the absence of functional rho means the transcription continues beyond the proper termination point.
Answer:
d. Some RNA molecules would be normal length because not every terminator in bacterial genes would be rho-dependent.
Explanation:
Rho is a prokaryotic protein which is required at the end of transcription (termination) of dependent rho-terminator sequences. During transcription, Rho binds at the end of the single-stranded RNA sequence in a site known as 'transcription terminator pause site'. This factor has helicase activity dependent on the hydrolysis of Adenosine triphosphate (ATP) to ADP. The Rho binding site consists of a cytosine-rich region (∼ 70 nucleotides) that lacks RNA secondary structure.

One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. This is called:______
a. deletion
b. inversion
c. duplication
d. translocation
e. aneuploidy
Answer:
The correct answer is: translocation.
Explanation:
When a chromosome breaks, there are many ways in which this can affect the integrity of the genes, as it can cause the deletion of one or several parts of the DNA. Other abnormalities include duplication and inversion of the genes.
When one fragment of the DNA breaks and joins a nonhomologous chromosome, the event happening is a translocation. There are two types of chromosomal translocations:
reciprocal translocations, in which the involved chromosomes exchange segments with one another.Robertsonian translocations, in which an entire chromosome joins another chromosome's centromere.Depending on the type of translocation and the amount and nature of the genes, this abnormality can affect individuals in different degrees.
Aneuploidies, on the other hand, are not related to the integrity of the chromosomes but rather the number of chromosomes. While euploidy refers to a total of 46 chromosomes in humans, aneuploidy describes individuals with more or fewer chromosomes.
All of these anomalies can be identified with a karyotype.

Which of the following promotes the rapid growth of bacteria?
А
Food held between 70-125° F
B
Cooking foods for long periods of time
с
Foods that are very dry
D
Foods that are held just above freezing
Answer: А . Food held between 70-125° F
Explanation:
Bacteria needs favorable FAT TOM conditions to grow. This means that bacteria needs favorable Food, Acidic conditions, Temperature, Time, Oxygen and Moisture conditions to grow.
When it comes to temperature, there is something called the Danger Zone where bacteria can rapidly grow and multiply by a rate of up to double every 20 minutes.
This danger zone is between 40°F - 140°F which means that food held at 70-125° F is in that danger zone and will promote the rapid growth of bacteria.
A. Food held between 70-125° F promotes the rapid growth of bacteria. Option A is correct.
The temperature range between 70-125° F (21-52° C) is commonly known as the "danger zone" for bacterial growth. Within this temperature range, bacteria can multiply rapidly and pose a risk of foodborne illness. This temperature range provides optimal conditions for bacterial growth and reproduction.
Bacteria thrive in warm and moist environments, and temperatures within the danger zone provide the ideal conditions for their proliferation. When food is held within this temperature range for an extended period, bacteria present on the food or introduced from the environment can multiply quickly, increasing the risk of food contamination.
It is important to note that cooking food for long periods of time (B) and foods that are very dry (C) can actually inhibit bacterial growth. High temperatures during cooking can kill bacteria, while dehydration can reduce the water content that bacteria need for growth and survival. On the other hand, foods held just above freezing (D) slow down bacterial growth but do not promote rapid multiplication.
To prevent bacterial growth and ensure food safety, it is recommended to keep perishable foods either below 40° F (4° C) or above 140° F (60° C) to minimize the time spent in the danger zone. Proper cooking, refrigeration, and temperature control are essential practices in preventing bacterial growth and maintaining food safety.

Think and discuss: Paramecia that live in freshwater have contractile vacuoles, while those that live in salt water do not. Why do you think this is the case
Answer:
See the answer below
Explanation:
The contractile vacuole primarily functions for the excretion of excess water in organisms that possess the organelle. Paramecia that lives in freshwater would need to constantly get rid of excess water that is likely to be entering the cell due to the fact that the ambient water is hypotonic to their cells. The cytosols of paramecia that live in freshwater have a higher solute concentration and hence, lower water potential than the surrounding freshwater.
The paramecia that live in salt water do not have a need for the contractile vacuole because the problem of excess water entering their cells may not arise. The salt water may not be hypotonic to the cytosol of the paramecia.
Paramecia are single-celled eukaryotic organisms, which are found in aquatic habitats. They are long and slipper-shaped organisms, which have many membrane-bound cell organelles.
The paramecium is the protists, which are found in the marine habitat. The organisms are eukaryotic and have well-developed cell organelles.
The presence of contractile vacuoles in the paramecium regulates the osmoregulation and discharge of excess water. The contractile vacuole controls the intracellular water balance by discharging or accumulating excess water.
The saline water has a high concentration of salt, whereas the freshwater does not have salty compounds.
Thus, the paramecium in saline water has contractile vacuoles to regulate osmoregulation.

PLEASE HElp 15 points If a scientific idea has been proven 100% of the time, like gravity, it becomes a blank
whereas an idea that is generally believed but has not been proven to be 100% true would be called a blank
Answer:
If a scientific idea has been proven 100% of the time, like gravity, it becomes a theory, whereas an idea that is generally believed but has not been proven to be 100% true would be called a hypothesis
Explanation:
In scientific research, a hypothesis is an idea put forward before any research has been completed. It is based on previous data, and requires scientific testing before it is confirmed and becomes a theory.
A theory is a principle put forward to explain a range of observations. For example, multiple lines of evidence support the theory of evolution. There is no significant data that refutes the theory.
