Answers:
1. Adaptations to survive in specific island conditions:
Morphological adaptations for eating food resources from a specific island. For example, a mandibular structure adapted to eat the food that they obtain.
Behavioral adaptations to avoid depredators. For example, diurnal habits because predators have nocturnal habits.
Physiological adaptations to survive in specific conditions. For example, a lower metabolic rate if food resources are limited.
Stress-induced adaptations to survive in specific stressful conditions. For example, reduction in transpiration is a stress-induced adaptation that enables to rat survive if water resources are limited.
2. Example: Introduction of the rat with diurnal habits in the island with predators that has the same habits is a challenge to survive in this new environment. In this case, the rat can develop different strategies to avoid predators: specific sounds to alert other members of the population on the presence of predators, an immobile pose to simulate death, etc.

Compounds like the pesticide DDT may bring about the evolution of new strains of organisms by...?
(1) destroying food producers
(2) acting as natural selecting agent
(3) mixing two different sets of genes
(4) creating new ecological niches
Answer:
(2) acting as natural selecting agent
Explanation:
Compounds like the pesticide DDT may bring about the evolution of new strains of organisms by acting as a natural selecting agent.
Evolution is generally defined as a gradual change to the characteristics of organisms over a period of time.
When DDT is used on a particular population of pest, those that are weak within the population die off, leaving only those that are strong within the population to survive and multiply. The DDT acts a selecting agent for the survival gene in the pest and the survived gene eventually evolve into a new, DDT-resistant strain pest in no time.
The correct option is option (2).
La Rafflesia arnoldii es una planta tropical con una enorme flor rojo-sangre, que emite calor y despide olor a carne descompuesta. ¿para qué le sirven a esta planta estas adaptaciones?
Answer:
Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant
Explanation:
The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.
Its possible Endothermy characteristic is for mimicry Its releases heat to attract the pollinators- blowflies.The endothermic mechanism is well pronounced during flora development: which further buttress the fact that this is related to pollination to attract blowflies, and not to thermoregulation.

Answer:
true (more info below)
Explanation:
The continental crust is a sheet of granite, sedimentary and metamorphic rocks that surround the continents and the shallow seabeds near their coasts, known as the continental shelves. This is less thick than the substance of the mantle of the Planet, which therefore "floats" on top of it.

When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in complexity?
Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems

What is the name of the organic molecule modeled below? A propane B propene C propyne
The given organic molecule is the structure of propene. The given molecule has a single double bond. Hence, Option B is the correct answer to the statement.
How is nomenclature done?The organic molecule nomenclature is determined by the presence of a single bond, double bond, or triple bond. The functional group has an important role too.
The single carbon is called mono. if two carbons are present, the compound is called di. if three carbons are present, the compound is called prop. In the given molecule, there are three carbons.
If a single bond is present, that bond is called "ane." If a double is present, it is called "ene". "Yne" is called when three bonds or triple bonds are present. By combining the carbon number and the bond, the nomenclature is complete. Here, three carbon molecules are present with a double bond; hence, it is called propene.
Hence, the correct answer is option B, which is propene.

Can seaweed help curb global warming? (At least 7 sentences)
Answer:
Professor and climate change activist Tim Flannery believes that massive farms of seaweed, a crop with enormous carbon sequestration capabilities, could potentially draw enough carbon dioxide from the atmosphere in a short enough time frame to mitigate some of the worst effects of climate change. Flannery acknowledges that his radical approach could raise some negative externalities, and sweeping carbon under the ocean isn’t a permanent solution. But for those who worry that the climate crisis is a lost cause, he offers reassurance that climate change is a soluble issue.

How do environmental signals, like light influence the distribution of auxin in a plant? A. By increasing the concentration of auxin B. By destroying the auxin C. By causing auxin to migrate in to the shaded portion D. By decreasing the cells sensitivity the auxin
Answer:
C. By causing auxin to migrate in to the shaded portion
Explanation:
Auxin is the most important plant hormone involved in the apical growth of plant parts. Auxin is evenly distributed in a plant with a normal light condition, however, when a particular part of a plant is exposed to sunlight, that illuminated part contains less auxin. The hormone is transported to the shady part of the plant via diffusion.
This causes more auxin to be present in the shady part than the illuminated part, hence, the shady part experiences a faster and elongated growth. This elongated growth in the shaded portion of the plant causes it to grow towards the direction of the light, a process called PHOTOTROPISM.

Explanation:
No, they are not the same species.
Are mammoths and mastodons the same species?Despite the superficial resemblance, mastodons were distinct from mammoths. Mastodons were shorter and stockier than mammoths with shorter, straighter tusks. Mastodons were wood browsers and their molars have pointed cones specially adapted for eating woody browse.
Are mastodons and mammoths related?While mastodons look a lot like modern elephants, they are not closely related. The ancestors of modern elephants and mammoths went their separate ways about 5 million years ago, and mastodons branched off even earlier, about 25 million years ago.
