My best guess would be the first option.
Explanation:
For example, when people began chopping down trees and making settlements in South America, fire ants started to move north in search for new homes. Eventually, they've became a huge problem to North America due to North America having no natural predators capable of eating these violent ants.
Answer:
Por ejemplo, cuando la gente comenzó a talar árboles y hacer asentamientos en América del Sur, las hormigas rojas comenzaron a moverse hacia el norte en busca de nuevos hogares. Con el tiempo, se han convertido en un gran problema para América del Norte debido a que América del Norte no tiene depredadores naturales capaces de comerse estas violentas hormigas.

Why do water molecules "stick together"?
Answers

Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged. ... All water molecules are exerting cohesive forces on all the molecules around them including those on the surface of a body of water
What is responsible for the red tide phenomenon? It is a phenomenon that usually coincides with storm surges; the name comes from the red kelp that often washes ashore as a result of rough weather. Red tide occurs in patches of water where certain species of dinoflagellates flourish. They are so abundant that the water becomes discolored and takes on a red hue. Red tides occur once a year and in accordance with the lunar cycle. The water appears red as a result of reduced levels of photosynthetic pigmen
Answers
Answer:
Red tide occurs in patches of water where certain species of dinoflagellates flourish.
Explanation:
Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.
Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.
Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.

The presence of a negative allosteric effector on an allosteric protein would: a. cause a shift to the left in the sigmoidal curve. b. increase the number of R conformations. c. decrease the cooperativity of the substrate. d. raise the apparent value of the equilibrium constant, L. e. increase the likelihood of the binding of S.
Answers
Answer:
d. raise the apparent value of the equilibrium constant, L.
Explanation:
Allosteric regulation is a type of regulation of an enzyme by binding an effector molecule at a site other than the protein's active site (i.e., the allosteric site). The equilibrium constant (L) refers to the transition between two forms of an allosteric protein in absence of a ligand. The properties of allosteric enzymes are explained by conformational changes associated with a low-affinity tense (T) state, or a high-affinity relaxed (R) state. Negative allosteric effectors are molecules that bind to the allosteric site on an enzyme in order to decrease its activity, thereby leading the enzyme to a low activity T state and thus increasing the value of the equilibrium constant.

Why are coral reefs important to ocean life? Coral reefs take carbon dioxide out of the water and secrete it into their skeletons. Corals provide an important cleaning function by filtering debris from the water. Corals are an important link in the benthic food chain. Coral reefs provide food, shelter, and breeding grounds for thousands of marine organisms. Coral reefs grow upward to near sea level, providing shallow zones for benthic organisms.

Explain why the biomass of secondary consumers is always lower than the biomass of primary consumers.
Answers
Answer:
Because energy is lost in the transfer from one level to the next, there is successively less total energy as you move up trophic levels. In general, we would expect that higher trophic levels would have less total biomass than those below, because less energy is available to them.
One gene pair can influence other gene pairs, with their combined activities producing some effect on phenotype; this called ________________. In Labrador retrievers, one gene pair codes for the quantity of melanin produced while another codes for melanin deposition. Still another gene locus determines whether melanin will be produced at all--lack of any produces an albino (recessive).

Epistasis
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants
In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.

A eukaryotic cell carries out phagocytosis and engulfs a gram-negative bacterial cell, which ends up in the resulting food vacuole. Hypothetically, to go from the cytosol of this bacterial cell to outside of the eukaryotic cell that has taken it in, what is the least number of biological membranes that would have to be crossed

This finding provides the strongest evidence for:
Answers
Answer:
Feature detection
Explanation:
Feature detection involves different neurons that are activated in response to specific stimuli. For example, feature detectors are activated in the cerebral cortex through visual stimuli of specific shapes or patterns. These neurons become more and more complex as the stimuli also become progressively more complex and specific. Featured detector neurons have been identified in the toad vision, where they have been involved in the toad's behavior in response to worm-like moving stimuli (e.g., orienting), and the bat auditory cortex, where they have been involved in the measurement of the distance between the bat and its prey.
The prevalence of CRE infections in health care settings has increased significantly in recent years, in part because these organisms are able to share plasmid-encoded resistance genes. Which method of horizontal gene transfer is most likely responsible for transfer of the plasmid between bacteria
Answers
Answer:
Bacterial conjugation
Explanation:
Carbapenem-resistant Enterobacterales (CRE) are different types of bacteria that lead to infections in healthcare settings. Moreover, a plasmid is a small piece of DNA that can replicate independently from the bacterial chromosome. Bacterial conjugation is a type of horizontal gene transfer by which plasmids are transferred from one bacterium referred to as 'donor' into another called 'recipient' by sex pili. Plasmid transfer is unidirectional and depends on physical contact between bacterial cells. In this case, it is expected that this type of DNA transport mechanism occurs among patients occupying the same rooms in healthcare settings.

The compound 2,4-dinitrophenol (DNP) is a lipid soluble compound that has been used as a weight loss agent. It functions this way by causing the inner mitochondrial membrane to become leaky with respect to protons. Which result might be expected if cells treated with DNP were examined in detail
Answers
Answer:
ATP production would be slower in these cells than in untreated cells
Explanation:
Oxidative phosphorylation is the third stage of cellular respiration, which occurs in the mitochondria of animal and plant cells. Oxidative phosphorylation represents the most efficient pathway to generate energy in animal cells by the production of Adenosine triphosphate (ATP) as a consequence of the transfer of electrons from nicotinamide adenine dinucleotide (reduced form) (NADH) or flavin adenine dinucleotide (reduced form) (FADH2) to molecular oxygen (O2) through a sequential series of electron carriers. The 2,4-Dinitrophenol (DNP) poison is an uncoupler of oxidative phosphorylation that carries protons across the mitochondrial membrane, thereby leading to a rapid consumption of energy without the production of ATP. This mitochondrial uncoupler (DNP) has been used as a dieting drug during the 30's decade (1930), but was rapidly banned due to its side effects, which include, among others, tachycardia, hyperthermia, tachypnea, and metabolic acidosis.
