Scientists who study changes in the diversity of a population at the level of the gene are called _____ geneticists.
Answers
Scientists who study changes in the diversity of a population at the level of the gene are called population geneticists.
Population genetics is the branch of genetics that focuses on the study of genetic variation and the mechanisms that can change the frequency of genes and alleles within populations over time.
Population geneticists use mathematical models and statistical methods to understand how genetic variation arises and is maintained in populations, how it is influenced by factors such as mutation, migration, genetic drift, natural selection, and non-random mating, and how it can lead to evolutionary change.
They also use genetic data to reconstruct the history of human populations and to infer evolutionary relationships among species.
Population genetics is an important tool for many fields of biology, including ecology, conservation biology, medicine, and agriculture.

Read the following excerpt about stem cells. Then use your knowledge about gene regulation to make a claim as to why stem cells function differently from differentiated cells.
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
Answers
Answer:
''Stem cells makes copies of itself whereas differentiated cells can't.''
Explanation:
stem cells function differently from differentiated cells because the stem cells divide and make copies of itself. It has the potential either to remain a stem cell or become another type of cell such as a muscle cell, a red blood cell, or a brain cell if the body needed while on the other hand, differentiated cells are specialized cells which performs specific functions and unable to divide.
Answer:
Stem cells are unspecialized cells that can make copies of themselves without limits when needed whereas differentiated cells can't, instead they become specialized as their body develops.
Explanation:
The second messenger _____ is produced by the enzyme _____. nitric oxide; arginase cGMP; GTP cyclase cAMP; adenylate cyclase triacylglycerol; phospholipase C inositol diphosphate; phospholipase C
Answers
The second messenger cAMP is produced by the enzyme adenylate cyclase.
Adenylate cyclase is the enzyme responsible for producing the second messenger cyclic adenosine monophosphate (cAMP). When a signaling molecule binds to a G protein-coupled receptor (GPCR) on the cell surface, it activates a G protein, which in turn activates adenylate cyclase. This activation leads to the conversion of ATP (adenosine triphosphate) into cAMP.
cAMP acts as a second messenger by relaying signals from the cell surface to the intracellular components, ultimately triggering various cellular responses. It accomplishes this by binding to and activating protein kinase A (PKA), which phosphorylates specific target proteins, thereby modulating their activity. This phosphorylation cascade initiates a chain of events that regulate processes such as gene expression, cell growth, metabolism, and neurotransmitter release.
The production of cAMP is tightly regulated and occurs in response to various extracellular signals, including hormones, neurotransmitters, and environmental stimuli. By using cAMP as a second messenger, cells can efficiently transmit and amplify signals from the extracellular environment to the intracellular machinery.

Where do snakes get their MATTER from?
Answers
Snakes are necessary to maintain ecological equilibrium. In most ecosystems, snakes can be both prey and predator. Seasonal behaviors like mating, laying eggs, or giving birth to live children are brief.
When a large prey population attracts and sustains a large snake population, these snakes become birds, animals, and even other snakes' prey. Some snakes specialize in eating other snakes, like the kingsnake, which is immune to the venom of rattlesnakes and can eat rattlesnakes. The Southeast Asian king cobra is the world's longest venomous snake and an expert snake eater.

A species of birds lives in the jungle. They have long, thin beaks that allow them to find ants and other things to eat deep inside of tree trunks. Both male and female birds have large talons (claws) that allow them to hold onto tree branches as they pick at the trunks. The males have colorful feathers that help them attract females. The females, on the other hand, have larger tails that they flutter when they are ready to reproduce. Recently, developers have been cutting down many of the trees that these birds rely on for food to make room for more buildings. Which of the following describes how the birds will most likely be affected by the change?
Answers
The tree-cutting will probably have a severe impact on birds with long, thin beaks and large talons. Their ability to survive and procreate could be impacted by the decreasing availability of their food source and habitat.
Might the overall population be impacted by the decline in bird populations brought on by tree-cutting?The loss in bird populations brought on by tree-cutting may indeed affect the males' capacity to attract females and the females' capacity to locate compatible mates, potentially resulting in a decline in the population as a whole. This emphasizes how crucial biodiversity and natural habitats are to the health of ecosystems.

in which direction do the peristaltic contractions of the stomach's smooth muscle move contents from the body to the fundic region from the pyloric region to the fundic region
Answers
To move its contents from the fundus to the pyloric region, the stomach's smooth muscle contracts peristaltically. The one that makes the greatest sense is "e. none of them above".
The fundus is the most proximal portion of the stomach, and the gastric cardia is its most distal component.
A series of wave-like muscular contractions known as peristalsis is what moves food through the digestive tract. The action starts in the oesophagus, where large balls of food are transported to the stomach by strong waves of smooth muscle. There, peristalsis takes place and the meal is subsequently digested into a liquid substance known as chyme. If you extend a section of intestine, it can be easier to see the wave-like motion.

The majority of dissolved tons in seawater is , roughly a 0.5M NaCl concentrationThe lonization constant of is 2.0. Calculate the solute potential for seawater if you know that the water is 2C
Answers
The solute potential for seawater is -2.6 kPa.
What does solute potential mean?When a solute is dissolved in water, it is less likely to osmotically diffuse away than when it is not. A solution's water potential will be lower and more negative than that of pure water.
Additionally, as there are more solute molecules present, the solute potential becomes more negative. Many different living species are significantly impacted by osmotic potential. If a live cell is surrounded by a more concentrated solution, it will likely lose water as a result of the environment's higher water potential. Both marine creatures that live in sea water and halophytic plants that grow in salty conditions can demonstrate this.

FILL IN THE BLANK. When a skeletal muscle contracts, the ____ filaments slide deeper into the ____ bands, pulling on the z lines and shortening the sarcomere
Answers
The z lines are pulled on and the sarcomere is compressed when skeletal muscle contracts because the actin filaments have moved deeper into the presynaptic bands.
According to the sliding filament theory, sarcomeres within a muscle fibre shorten as a result of myosin filaments pulling actin filaments closer together during muscular contraction. A muscle fibre contracts when all of its sarcomeres shorten.The synapse between a motoneuron and a muscle fibre, known as the neuromuscular junction, is where skeletal muscle contraction starts. The voltage-gated calcium (Ca2+) channels of the presynaptic membrane open as a result of action potential propagation to the motoneuron and subsequent depolarization.

thioesters can release more energy upon hydrolysis than regular esters. explain in 2-3 sentences.
Answers
Thioesters can release more energy upon hydrolysis than regular esters because the sulfur atom in thioesters is more polarizable than the oxygen atom in regular esters, allowing for greater stabilization of the leaving group during hydrolysis.
This results in a more favorable and exothermic reaction, releasing more energy. Thioesters can release more energy upon hydrolysis than regular esters due to the difference in bond strength between the thioester bond and the ester bond. The thioester bond is weaker than the ester bond, which means it requires less energy to break, resulting in a more exergonic hydrolysis reaction and release of more energy.
