Answers
Active transport is one of the three types of substances transport accross the membrane. It needs energy to occur because it moves molecules against their electrochemical gradient. Pump protein and carrier proteins are involved in active transport. Phagocytosis, Endocytosis, Exocytosis, Pinocytosis are examples of active transport.
What is active transport?Active transport is one of the three cellular transmembrane types of transport. The other two are passive transport and simple diffusion.
Active transport acts against the electrochemical gradient, so it does need energy to transport substances.
It carries molecules from a low-concentration side of the membrane to a high-concentration side.
The energy used comes from
ATP ⇒ Primary active transportMembrane's electric potential ⇒ Secondary active transportCarrier proteins are involved in active transport.
Pump proteins, like Na-K pump, expell Na and enters K into the cell.
Among the different types of active transport we can mention endocytosis, exocytosis, pinocytosis, and hagocytosis.
These processes refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

This element can form a wide variety of substances, including long chains. The different substances it forms are central to the molecules found in living things.What element it this?a) carbonb) oxygenc) hydrogend) nitrogen
Answers
Introduction to Biology: Biomolecules
In the options, they are listing the four more abundant elements in living beings: carbon (C), hydrogen (H), nitrogen (N), and oxygen (O). Given that all of them are essential to forming the molecules found in living beings, we need to check their chemical properties, because they are telling us that is an element that can form long chains.
• Hydrogen, has only 1 electron and can form one bond at a time, so it cannot form long chains
,• At normal conditions, ,Oxygen, form molecules of only 2 oxygen atoms (O₂), not long chains.
,• Nitrogen, is a similar case to oxygen because at standard temperature and pressure it forms a diatomic gas (N₂)
,• Carbon ,has ,4 atoms that can form covalent chemical bonds,, which allows it to form ,polymers, at, standard temperatures.
This means the correct answer is a) carbon.

while chloroplasts evolved from
Answers
Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

Increase amount of other plant species, decreased amount of water.C. Decreased amount of herbivores, increased amount of sunlight.D. Increased amount of herbivores, increased amount of water.
Answers
All plants need the right temperature, light, water, air, and food to have a proper metabolism and to grow. The height of the plant is directly related to the number of nutrients in the soil and the light for its photosynthetic processes. On the other hand, the lower the number of herbivores, the less likely it is that the branches will be cut and the height of the plant will be reduced.
We can conclude that the correct answer is:

Student #1 is WRONG and Student #2 is CORRECT! You are student #2. Write a CER and explain how energy is passed through the ecosystem and why it is easier for grass to acquire energy than it is for a hawk.Try to use all the words in the word bank below to help you complete your open response CER. Review the RUBRIC WORD BANK: food web, the sun, food pyramid, producer, consumer, tertiary consumer, predator, autotroph, heterotroph, decomposer, predator, prey, herbivore, carnivore, omnivore.
Answers
The observation for the student #2 must starts by the claim, going to evidence, and finishing with the reasoning.
1 - Claim = To the grass (producer) is easier to acquire nergy than it is for a hawk (quartenary consumer), because the base of the food pyramid is where most of the energy of the food chain is maintained, and the producers are able to produce their own food from the natural resources in the environment;
2 - Evidence = The food web in the picture shows how the trophic levels are distribute in the ecosystem, being the food pyramid divided into: producers (autotroph organisms), consumers (primary-herbivores, secondary-omnivore, and tertiary-carnivore), predators, preys, and decomposers. The graph shows that from each levels a small quantity of energy is lost by the organisms, going from the levels with more energy (plants- that uses the sun to make photosynthesis) until the tertiary consumer (the pradator - hawk, that is a heterotroph). To have energy the plants need only to be in a good place, while the hawk have to go after preys and an environment that have a good balance between the trophic levels;
3 - Reasoning = The student #2 came to the conclusion that is much difficult for the hawk to obtain energy because of the observation of the challenges for each level tropic level being bigger and bigger. That's because the way that each organism get their food and what it eats is a determinant factor, as well the loss of energy to complete the most basic functions. Being the conclusion that the grass that just need sunlight and water have a lot less difficults and energy loss than a hawk that needs to hunt for food, survival, reprodutive needs and so on.

Poikilotetherms - how they use behavior to maintain body temperature
Answers
Because poikilotherms lack the physiological ability to generate heat, their body temperature tends to conform to that of their surroundings in the absence of any behavioral intervention. Poikilotherms include "cold-blooded" animals (Kearney et al.).
How poikilotherms maintain their body temperature?
Cold stress or heat shock can alter membrane properties in poikilotherms, causing damage and, potentially, death if not corrected quickly. Low temperature stress is mitigated by modifying membrane lipids to lower their average transition temperature.The hypothalamus, a part of our brain, regulates our internal body temperature. The hypothalamus compares our current temperature to the normal temperature of around 37°C. If our body temperature falls too low, the hypothalamus ensures that heat is generated and maintained.The metabolic rate of poikilotherms increases with increasing temperature. Poikilotherms respond to temperature increases with a standard performance curve that includes increased performance, a maximum, and then declining performance as temperature rises further.To learn more about : Poikilotherms

Answers
The fluorescence microscope differs from the compound light, and transmitted light, not so much because of the structure, but instead because of how light is used to generate an image/ see the sample.
In the fluorescence microscope, the light does not go through the sample per se, instead, a filter is needed, it works with a higher wavelength, in this case, the light rays go to the sample and excite the species marked with the fluorescence substance, that is to say, the sample must be previously treated so it can absorb light and re-emitted as fluorescence (electromagnetic radiation) therefore creating an image, of light. This is possible due to the proprieties of some molecules, such as fluorochromes.
