Beetles come in a wide variety of shapes, feeding habits, and live in a variety of habitats. Classifying beetles can be quite difficult given their sheer numbers. Within the Ground Beetles in Genus Notiophilus alone there are 15 different species. If you were to choose a group of organisms the LEAST related to individuals in this genus, you would look in which of the following taxa? In the same Kingdom, but not the same Phylum In the same Domain, but not the same Kingdom In the same Class, but not the same Order In the same Family, but not the same Genus
Answer:
In the same Domain, but not the same Kingdom
Explanation:
The taxonomic classification is organized in the following taxes, following the order of greatest kinship to the order of lowest biological kinship: species, genus, family, order, class, phylum, kingdom and domain. Therefore, if you want to study organisms that are less genetically similar to the organisms that make up the genus Notiophilus, you should observe the individuals that make up the domain where this genus is inserted, since they have very little genetic and morphological similarities.

The pH of blood is not affected by: ______a. hyperventilation.b. the pKa of acetic acid or acetate. c. consuming large amounts of sodium bicarbonate.d. fasting and starvation.
Answer:
The correct option is the pKa of acetic acid or acetate.
Explanation:
The blood pH is affected by hyperventilation since it triggers hypercapnia, an increase in metabolic acids and therefore a decrease in blood pH.
Excessive consumption of sodium bicarbonate, since this would alkalize the blood, and finally, prolonged fasting or excessive hunger generates the degradation of fat sources, with the consequent formation of ketone bodies as a product, and therefore entering a metabolic acidosis.

Describe how replacing diesel/petrol fueled vehicle to electric-operated vehicles may change the environment
Answer:
By reducing the amount of carbon dioxide emissions contributing to global warming
Explanation:
Global warming is an arising problem caused by the emission of gases called GREENHOUSE GASES into the Earth's atmosphere. The greenhouse gases include Carbon dioxide, methane etc.
Carbon dioxide as the principal cause of global warming is emitted when fossil fuels like petroleum products like diesel or petrol are burned. Therefore, the use of automobiles like cars releases CO2 into the atmosphere. Therefore, replacing diesel/petrol fueled vehicle to electric-operated vehicles may change the environment by reducing the amount of greenhouse gases (CO2) emitted into the atmosphere, ultimately helping to reduce global warming.
Corals form symbiotic relationships with microscopic photosynthetic algae that live in their cells and give the corals their distinct colors. The relationship is an example of mutualism, in which both species benefit. Predict how each organism in this relationship could benefit the other.
Answer and Explanation:
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments . They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles, that are colorful and provide nutrients to the coral.
Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals. Algae can store nitrogen in their tissues as nitrogen-rich crystals, which are constantly provided to corals.
This symbiotic relation allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.

During the cell cycle, the cell must pass through several checkpoints that confirm that the cell is ready to progress to the next phase of the cycle. If the requirements of one phase have not been met, the cell cannot proceed to the next phase. These checkpoints help control the rate of cell division. If a mutation disables one of these checkpoints, what is most likely to happen
Answer:
The correct answer would be - Cells begin dividing faster, leading to cancer.
Explanation:
In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.
These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.
Thus, the correct answer is - Cells begin dividing faster, leading to cancer.

a- Se hacen más angostos.
b- Se hacen más anchos.
c- Permanecen del mismo tamaño.
d- Se pierden.
Answer:
b- Se hacen más anchos.
Explanation:
Los conductos o vasos linfáticos son tubos que transporta tanto al líquido linfático (linfa) como glóbulos blancos que fluyen a través del sistema linfático. Estos conductos se inician en el intersticio y terminan en conductos de mayor tamaño que desembocan en la base del cuello, entre las venas yugular interna y la subclavia. A medida que va entrando en los tejidos, los conductos linfáticos se van haciendo cada vez más angostos y finos, convirtiéndose finalmente en capilares linfáticos, donde las sustancias que no pueden penetrar los vasos sanguíneos son recogidas por estos capilares.

F) -Glu-Leu-Ala-Lys-Phe-
G) -Tyr-Trp-Phe-Val-IIe-
Answer:
The correct answers are "amino acid3" and option F) "-Glu-Leu-Ala-Lys-Phe-"
Explanation:
The alpha helix is one the most common secondary structures of proteins, characterized by seven residue repeating units that alternate hydrophobic and hydrophilic residues. This sequence match with the peptide segment "-Glu-Leu-Ala-Lys-Phe-", where glutamic acid (Glu) is hydrophilic, leucine (Leu) is hydrophobic; and it does not contain amino acids that disrupt alpha helix such as proline and glycine. The alpha helix structure is stabilized by hydrogen bonds within the residue's backbone, one of them stablished between the third and the seventh amino acid residues.

create a flowchart of the negative feedback mechanism that controls your body’s temperature
Answer:b) Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body.In negative feedback, the body works to correct a deviation from a set point, it tries to get back to normal. ... In positive feedback, the body changes from the normal point and amplifies it. Examples include blood clot formation, lactation, contractions during childbirth, and fever.In positive feedback mechanisms, the response to a stimulus does not stop or reverse it but instead keeps the sequence of events going up. ... A positive feedback mechanism can be harmful, as in case of fever that causes metabolic changes pushing it to be higher.xamples of processes that utilise negative feedback loops include homeostatic systems, such as:
Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels)
Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low)

Jerome solves a problem using the law of conservation of momentum. What should Jerome always keep constant for each object after the objects collide and bounce apart?
velocity
mass
momentum
direction
Answer:
mass
Explanation:
The law of conservation of momentum states that within an isolated system, one of the quantities must be conserved no matter what happens. In the case of the question above, when two objects collide and separate from each other. Because of the collision and the removal of objects, it is not possible to keep the direction and speed that they assume constant. However, the mass of the bodies will be maintained at all times, before, during and after the collision; steadily.
The only parameter Jerome should keep constant is mass of the object.
Law of conservation of momentumThe law of conservation of momentum states that, the total momentum of an isolated system is always constant.
The formula for law of conservation of momentum is written as;
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
where;
m is mass u is initial velocityv is final velocityThus, the only parameter Jerome should keep constant is mass of the object.
