Most lipids are composed of long chains of carbon and hydrogen atom.
Lipids are the long chains of hydrocarbons. These are the organic compounds that are abundantly present in living body. The role played by lipids inside the body are: they are important components of the membrane of cell and cell organelles; and they are great source of energy (in the form of fats).
Carbon is the most essential element in the living organisms. Its atomic number is 12. It is the basic element present in all the organic molecules. The catenation property of carbon contributes to its importance and versatility.

True or False: Active Transport requires
ATP to transport molecules with the
concentration gradient.
Answer:
the statement is true
Explanation:
The main difference between active and passive transport is that in active transport, solutes are moved from an area of low to high concentration (against the concentration gradient) and requires the energy released from ATP hydrolysis
Answer:
Explanation:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
Hence; your option is True
Choose a meat product that you eat, and construct a food chain that includes you as the final
consumer.
Typical meats include beef, chicken, turkey, and pork. Even though pigs are omnivores, all of these animals are mostly herbivorous.Animals find food along a single path, creating a feeding chain.
What is a Food Chain List?The way each living thing obtains its food is shown by a food chain. Some animals eat vegetation, while others prey on other creatures.For instance, a straightforward food chain connects trees and bushes, giraffes (who consume trees and shrubs), and lions (that eat the giraffes).It's a cliché that we've all heard thousands of times, whether to defend how we treat other animals or just to celebrate a carnivorous lifestyle: humans are at the top of the food chain.Each link in this chain provides food for the next link.However, ecologists have developed a statistical method for determining a species' trophic level—its position in a food chain.To learn more about What is a Food Chain List refer to:

According to recent research, we actually fall between between pigs and anchovies. With polar bears and orca whales at the top of the food chain, that places humans directly in the middle of the chain.
To create a food web, write out the primary producers, herbivores, omnivores, and carnivores for the chosen habitat. Connect them with arrows showing both predator and prey.

Summarize what happens during the Calvin cycle.
The Calvin cycle is a series of chemmical reactions that are part of the dark reactions of a photosynthesis, turning carbon dioxide into sugar. It is composed of three main phases:
1 - Carbon fixation, in which carbon dioxide (CO2) is turned from the inorganic molecule that it is to an organic molecule.
2 - Reduction, in which energy from ATP and from NADPH is used to convert the organic carbon molecules into a simple sugar
3 - Regeneration, in which glucose is produced and the molecule that started the cycle is regenerated so the cycle can continue, as the cycle must be completed a three times until it has produced the product molecules (six G3P's - Glyceraldehyde 3-phosphate).
Which of the following steps in a signaling pathway typically occurs first once a chemical messenger reaches a target cell?
Question:
Solution:
The cells recognize the stimuli (chemical messengers) through receptors. When the receptors bind to the signaling molecules, physiological responses are initiated, and depending on the nature of those physiological responses, the receptor will be a membrane receptor or an intracellular receptor. So, we can conclude that the correct answer is
A LIGAND BINDS TO A RECEPTOR.

Variable-ration schedules
Fixed-interval schedules
Variable-ration schedules is reinforcement schedule where appropriate movements are reinforced after a varying number of responses.
Partial reinforcement schedules is defined as either fixed or variable, and as either interval or ratio. Combinations of these four rubric produces four kinds of partial reinforcement schedules these are fixed-ratio, fixed-interval, variable-ratio and variable-interval.
A variable ratio schedule means that the reinforcer is delivered after an average number of correct responses has occurred. This schedule creates a very high rate of response. some examples are Gambling and lottery games.

Wildflowers are plants that grow on the forest floor.
During a study, a scientist observed that wildflowers began to bloom before the leaves appeared on the tall trees above them and stopped blooming once the trees were full of broad leaves which blocked the sunlight.
Evaluate this observation and explain a limiting factor this is affecting the wildflowers on the forest floor.
Answer: A limiting factor of wildflowers on the forest floor is the sunlight. This affects the plant because the wildflowers cannot grow without sunlight and when the leaves block the sunlight they cannot grow.

Answer
A. used by science to be an example for how other organisms would respond to different situations
Explanation
Model organisms are a non-human species that is extensively studied to understand particular biological phenomena.
Animal cells are most likely to experience damage froma. an aqueous solution.b. an isotonic solution.c. a hypotonic solution.d. a hypertonic solution.e. None of these.
Isotonic, hypertonic, and hypotonic refers to the concentration of solutes present in a solution in comparison to another solution.
In this case, they refer to a solution that surrounds animal cells.
When a solution is isotonic, it means that has the same concentration as the other, in this case, the cytosol of the cell, so there is no water flow across the cell membrane.
When the solution is hypotonic, water diffuses to the interior of the cell, which has a greater concentration of solutes, and in an animal cell this can cause the rupture of the cell, in opposition to what would happen in a plant cell, where the cell wall prevents this from happening.
And in the case of a hypertonic solution, as the concentration of solutes is greater outside the cell, the water leaves the cell.
This means that, from the options, a hypotonic solution can be more harmful to an animal cell (option C).

What 3 kinds of biodiversity are there?Genetic, species, and ecosystem diversity are the three levels of biodiversity that are most frequently discussed. The various genes found in each unique species of plants, animals, fungi, and microbes make up genetic variety. It can happen both within and between species.
It is essential to life on Earth that all living things are diverse, including ecosystems, plants, animals, their habitats, and their DNA. In addition to supplying oxygen, food, clean water, fertile soil, medicines, shelter, safety from storms and floods, a stable climate, and recreation, biodiversity is essential to human survival. Tragically, due to human civilization, biodiversity is currently vanishing at a rate 1,000 times faster than it should.
