Amy, a high-strung teenager, was suddenly startled by a loud bang that sounded like a gunshot. Her heartbeat accelerated rapidly. When she realized that the noise was only a car backfiring, she felt greatly relieved but her heart kept beating heavily for several minutes more. What hormone was released into her bloodstream that is causing this response
Answer:
Catecholamines, endothelins, glucocorticosteroids and thyroid hormones.
Explanation:
Catecholamines, endothelins, glucocorticosteroids and thyroid hormones are the type of hormones that is released into the bloodstream that causes increase of heart rate. Stress and anxiety is responsible for the raising of your heart rate. It may also increases when you're very happy or upset. People who have severe obesity can have a slightly faster pulse as compared to normal people.

The fibrous protein that gives skin its flexibility and helps skin regain its shape after being expanded is:
Answer:
Elastin
Explanation:
The elastin is defined as an extracellular matrix protein which lends to the elasticity and also resilience to the tissues such as the lungs, skin, arteries, tendons, and the ligaments.
Elastin synthesized from precursor molecule named tropoelastin.
Elastin is the fibrous protein which gives the skin its flexibility and also helps the skin regain its shape.

During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

what is photo synthesis
Answer:
Explanation:
Photosynthesis is the process of producing Glucose from CO2 and Water. The chemical reaction requires sunlight.
6H2O + 6CO2 ===> C6H12O6 + 6O2
If you are interested in the Environment, you should notice that plants take in CO2 and give away O2, the exact opposite of what animals and humans do. We should be extra careful about how we treat forests -- they produce what we need.

Describe the change in shape of the lens when a person looks from a near object to a distant object
Answer:
Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.
Red-feathered and blue-feathered birds occupy the same environment. The birds with the red feathers are better able to survive and avoid predators. This means that the population of red-feathered birds will increase in future generations. This illustrates the process of
Answer:
Natural selection.
Explanation:
Natural selection is the process in which the well suited organism is selected by the nature which is able to survive the environmental conditions while on the other hand, not well suited organisms are extinct from the environment. Due to this natural selection, the population of red-feathered birds will increase in the future as compared to blue-feathered birds which will be decreases due to susceptible to predators and environment.

Explanation:
Many antibiotics work by preventing the proper synthesis of the peptidoglycan cell wall. These antibiotics are most likely to be effective against what types of bacteria
Answer: Gram-positive bacteria.
Explanation:
Gram-positive bacteria are those bacteria that stain dark blue or violet by Gram staining. This is due to the structure of the cell envelope, since they possess a cell wall composed of a thick layer of peptidoglycan, which surrounds the previous one. The cell wall is attached to the cytoplasmic membrane by lipoteichoic acid molecules. The peptidoglycan layer confers high resistance to these bacteria and is responsible for retaining the stain during Gram staining. Unlike gram-positive bacteria, gram-negative bacteria have a second lipid membrane outside the cell wall and a single peptidoglycan layer.
An antibiotic is a chemical substance produced by a living being or synthetically derived, which kills or prevents the growth of certain classes of sensitive microorganisms, such as bacteria. An antibiotic could be bacteriostatic if it prevents the growth of bacteria or bactericidal if it destroys them.
Antibiotics usually attack cell walls, such as β-lactams that act on the peptide chains of the bacterial cell wall. That is, they act by inhibiting peptidoglycan synthesis. This is why gram-positive bacteria are susceptible to certain types of antibiotics because they possess a large amount of peptidoglycan.

The doubling time of a bacterium was measured at two different temperatures. Which results would be expected of a thermophile
Answer:
Increase in high temperature.
Explanation:
The population of the thermophile bacteria increase at high temperature as compared to other bacteria at high temperature because thermophile bacteria needs high temperature for growth and survival. Thermophile bacteria that flourish at relatively high temperatures ranging from 41 to 122 °C (106 and 252 °F) so we can conclude that the thermophile bacteria increase in population in the high temperature conditions.
What term describes the organisms that obtain energy from dead organic matter and aid nutrient cycling
Answer:
Decomposers.
Explanation:
Decomposers are the organisms that obtain energy from dead organic matter and help in nutrient cycling. The example of such type of organisms are bacteria and fungi. These organisms feed on the dead bodies of plant and animals. It perform two function i.e. clean the environment by removing the dead body through feeding on it and add nutrients in the soil which helps the plants to grow more efficiently.

The data of this lab
the
hypothesis because there was a difference in bird
beak distribution
Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.
Answer: 1. supported 2. when fruit was removed

punto de vista sobre la ley de mendel
Answer:
Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.
