Algae are microscopic plants that grow in the ocean. Algae must have sunlight, nutrients, and water to survive. What are these conditions called?
A. uncontrolled factors
B. limiting factors
C. necessary factors
D. non-living factors
Answer:
B) limiting factors
Explanation:
Phytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
In a balanced ecosystem, phytoplankton provide food for a wide range of sea creatures including krill, shrimp, snails, and jellyfish, that are in turn food for larger animals like sea turtles, fish and whales. However, under certain environmental conditions, such as the introduction of too many nutrients from land based sources of pollution, phytoplankton may grow out of control and form blooms.
These blooms can be problematic because the excess algae can block out sunlight, which is bad for plants like seagrasses that need sunlight to make food. Zooxanthallae, or symbiotic algae that live in the tissue of coral and supply coral with food, can also be impacted by algal blooms. Excess algae can also smother other critters living on the ocean floor.
When blooms eventually exhaust their nutrients, the phytoplankton die, sink and decompose. The decomposition process depletes surrounding waters of available oxygen, which marine animals need to survive. These oxygen-depleted waters are often called “dead zones,” since animals either die from lack of oxygen or leave the area to find more habitable waters.
The factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. limiting factors.
What are Limiting Factors?Limiting factors can be defined as those constrains that slows or stop the growth of a population. They may include food, biotic factors, or even competetion from other organisms in the environment for limited available resources.
Thus, factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. limiting factors.

Match the types of competition to their descriptions
So the 1st description is interspecific competition
2nd one is intraspecific competition
3rd one is interference
4th one is exploitation
Competition can be primarily categorized into perfect and monopolistic types with both showing demand elasticity in the long-run. Perfect competition has a perfectly elastic demand curve, while monopolistic competition has a demand curve that is not perfectly elastic, allowing some leeway in pricing.
Explanation:Types of Market Competition
Competition in economic markets can be categorized into different types which have distinct characteristics. The main types are perfect competition and monopolistic competition. In both cases, in the long-run, consumers are sensitive to price changes, which signifies demand elasticity. However, they differ in how firms face the price-demand relationship. Perfectly competitive markets feature perfectly elastic demand curves, meaning any price increase could eliminate demand for a product. Conversely, monopolistic competition presents a not perfectly elastic demand curve; firms have some market power to raise prices without losing all customers.
Key Comparisons and Concepts
Perfect competition serves as a theoretical benchmark to evaluate other market structures, which include monopolistic, oligopoly, and monopoly competetion. The amount of competition in a market impacts prices, as well as the demand and supply of goods and services. Moreover, exploring the evolutionary effects of intraspecific (within a species) and interspecific (between different species) competition can provide insights into how competition influences performance and survival strategies in biological ecosystems.

Predict the effect of a plant disease that
destroys all the chloroplasts in a plant.
Answer:
the plant will die
Explanation:
If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.
What is the role of the plants?Plants are the producers of the ecosystem that produces oxygen for itself and for all the animals, along with glucose. The chloroplast is the plant organelle that has thylakoids and stroma; in the thylakoids, water hydrolysis takes place and ATP is released, and in the stroma, carbon dioxide is fixed to form glucose. If these do not occur, the plant will be unable to produce all of them. Without the chloroplast and without food, they will perish.
Hence If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.

When do feedback loops fail to work on an ecosystem?
If you could explain the answer, that would be awesome :)))))
Answer:
Feedback loop will fail in an ecosystem if the factors regulating the feedback mechanisms fail to function.
Explanation:
Feedback loop is the phenomena in which output is circled back in a way that it is used as input again i.e the reaction is circled back. Its a continuous process.
There are two types of feedback loops, positive and negative, one functions to reinforce and other functions to balance. Positive feedback loops enhance the outputs while negative lower the output and keeps the balance. the variables that are involved in all these processes effect each others so, by eliminating such variables or factors will cause failure of feedback loops.

behavioral adaptation can be either instinctual or
Answer:
It can either be instinctual or learned.
Explanation:
An Instinctual behavior is one that a living being knows from the moment of birth, such as breathing or eating, but a Learned behavior is a behavior or habit acquired by personal experience, like speaking, walking, or playing video games.
Behavioral adaptation in animals can be instinctual or learned.
Explanation:Instinctual behaviors, not influenced by the environment, include innate responses such as mating systems or methods of communication. This kind of behavior is genetically embedded and could include actions like human babies grabbing a finger or birds migrating.
On the other hand, learned behaviors are influenced by environmental changes and previous experiences. Learning involves acquiring knowledge and skills through experience which enable an organism to adapt to its living conditions. Instances of learned behavior could include a creature's specific reactions to threats based on past encounters.
Therefore, instinctual behaviors provide a solid base of survival skills, while learned behaviors allow for versatility and adaptability in changing environments.

Guinea pig coat color is determined by a single gene. The allele for black coat color is dominant to brown. In a cross between two
black-haired guinea pigs, 20 offspring are born. If both parents were heterozygous, probability would predict that approximately how
many of the 20 offspring would have brown hair?
Answer: 5 would have brown hair.
Explanation:
In the cross between two heterozygous black guinea pigs, out of 20 offspring, we can expect approximately 15 to have black hair and approximately 5 to have brown hair, following Mendelian genetics principles.
Explanation:In genetics, a dominant allele masks the effect of the recessive allele making it less likely to appear in the offspring. In the cross of two heterozygous black guinea pigs, the four possible combinations of their alleles are BB, Bb, bB, and bb. The first three combinations will produce black offspring, while bb will give a brown guinea pig. This results in a 3:1 ratio, hence in the case of 20 offspring, about 15 would be expected to have black hair while 5 would have brown hair.
