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.

The factors such as sunlight, nutrient, and water to survive all cinditions that for algae bloom which are called: B. 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.

Answer: Option B

Explanation:

The oceans control the temperature by moving the hot air towards poles and cold air towards the equator. Ocean currents makes the colder air flow from the poles towards equator and hot air from from the equator to the poles.

It also makes the rain fall and helps in the regulating the temperature near the shoreline and makes it less variable.

So, the correct answer is option B

The ocean's ability to absorb and distribute heat leads to moderated and less variable temperatures in coastal areas, making option B the correct answer to how the ocean influences climate. So the correct option is B.

The question asks for an example of how the ocean influences climate. Among the given options, the correct answer is B. It causes temperatures near shorelines to be less variable. This is because oceans have a tremendous capacity to absorb and store heat, and they distribute this heat through their currents, stabilizing temperatures. Coastal areas benefit from these ocean effects, resulting in moderated climates with less temperature variation throughout the year.

Maritime Climates and Temperature Moderation

Water heats and cools more slowly than land due to its high specific heat capacity. This is known as 'thermal inertia', which enables coastal regions to experience milder climates, even in places that are far north, such as the coast of Norway. The interior of a continent, away from the moderating influence of the ocean, tends to have more extreme temperatures. On the coast, the differences in temperature are smoothed out, leading to less variable climates. Oceans also impact precipitation patterns, which can lead to climates that are not only milder but also can have increased rainfall, depending on global wind and current patterns.

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.

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.

Yes sand/silt have internal structures.

Explanation:

Sand is composed of silicon dioxide, in it silicon and oxygen atoms are joined by covalent bonds, it is mostly in the form of quartz and is in granular form.

Silt size is between sand and clay, composed of framework of silicon dioxide and feldspar.  

Digestion of a light meal typically takes 3 to 5 hours, starting from the stomach where it breaks down into chyme and passes through the ileocecal sphincter to the large intestine. The sphincter's relaxation is controlled by nerves and hormones triggered by stomach activity.

A light meal will typically digest within about 3 to 5 hours. The process starts in the stomach, where food is broken down into a substance called chyme. The food then passes through the ileocecal sphincter, a gate between the small and large intestines. This sphincter relaxes through the action of nerves and hormones, allowing food residue into the first part of the large intestine, the cecum.

The ileocecal sphincter is relaxed through two main factors. First, the digestive activity in the stomach provokes the gastroileal reflex, which increases ileal segmentation force. Second, the stomach releases the hormone gastrin, enhancing ileal motility and thus relaxing the ileocecal sphincter. After chyme passes through, backward pressure closes the sphincter, preventing backflow into the ileum.

Overall, the transit time and processing of the food through the stomach and small intestine usually takes 3 to 5 hours. However, retention time of food over the length of the whole intestine can be between 24 to 72 hours.

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.

According to the context, blood sugar, body water and temperature are conditions that need to be in balance for cells to function.

They are the conditions by which the process of cell maintenance is consistent with the internal environment and is carried out by the coordinated action of blood sugar, body water and temperature.

Body water needs to be in balance, that is, the relationship between the fluids inside the cell (intracellular) and its external environment (extracellular) for cells to function.

Statement C doesn’t describe about the function of aggressive animal behavior.

Instead of aggressive behavior, dominance is used to form hierarchy with non-violence. It is a sort of social pecking order that emerges when animals from a social gathering collaborate, to make a positioning framework.  

In social living gatherings, they are probably going to vie for access to constrained assets and mating openings. Instead of battling each time they meet, the relative position is set up between individuals from similar sex.

Thus, in order to establish hierarchy without violence, dominance is used.

Answer:

photosynthesis is important in many helio-centered plants

Explanation:

The light-dependent reactions of photosynthesis convert sunlight into chemical energy within the thylakoid membranes, where water is split to oxygen, protons, and electrons, producing ATP and NADPH as energy carriers for the Calvin cycle.

Light-Dependent Reactions of Photosynthesis

These reactions take place within the thylakoid membranes of chloroplasts. When sunlight hits the chlorophyll and other pigments, it excites electrons that move through an electron transport chain. This process leads to the splitting of water molecules (H2O) into oxygen, protons, and electrons (photolysis). The protons contribute to a proton gradient that drives the synthesis of adenosine triphosphate (ATP) through chemiosmosis. Moreover, the excited electrons transfer from the water molecules to nicotine adenine dinucleotide phosphate (NADP+), forming NADPH. The crucial raw materials for these reactions are water and sunlight, resulting in the production of oxygen, ATP, and NADPH.

All these products are then used in the Calvin cycle, or the light-independent reactions, to convert carbon dioxide (CO2) into glucose, a process powered by the ATP and NADPH generated in the light-dependent reactions.

This is mostly prevalent in South Korea, North Korea, United states, United Nations, Canada etc. This is mainly used in the steel making process and is combined with many alloys for enhancing their property.

To find the price of bituminous coal per million BTU's, we need to follow these steps:
1. Convert the price from tons to pounds:
  - Since there are 2,000 pounds in a ton, we can multiply $52/ton by 2,000 to get the price per pound.
  - $52/ton * 2,000 pounds/ton = $104,000/pound
2. Convert the heat content from BTU/pound to BTU:
  - Since there are 12,000 BTU/pound, we can multiply the price per pound by 12,000 to get the price per BTU.
  - $104,000/pound * 12,000 BTU/pound = $1,248,000,000/BTU
3. Convert the price to per million BTU's:
  - Since there are 1,000,000 BTU's in a million BTU's, we can divide the price per BTU by 1,000,000 to get the price per million BTU's.
  - $1,248,000,000/BTU / 1,000,000 BTU = $1,248 per million BTU's
Therefore, at $52/ton, the price of bituminous coal per million BTU's is $1,248.

The correct option is A. leg jumping when it is hit by a reflex hammer is the only brain-free option. It's a spinal reflex - a quick response through the spinal cord without needing the brain to process information.

Only the leg jumping when it is hit by a reflex hammer skips the brain. It's a spinal reflex for a quick response, while the others (B, C, D) rely on the brain to receive info and tell your body what to do (breathing, temperature, heart rate).

The other options (B, C, and D) require the brain's involvement and are not spinal reflexes:

B. Deeper breathing when you need more oxygen: When your body senses low oxygen levels (through blood chemistry changes), the brain receives these signals and triggers deeper breaths to increase oxygen intake.

C. Body temperature rising when you have an infection:  During an infection, the immune system releases chemicals that signal the brain to increase the body's core temperature, a defense mechanism.

D. Heart beating faster when you are in danger: When you perceive danger, sensory information reaches the brain, which activates the nervous system, causing your heart rate to increase to prepare for action.

In all these options (B, C, and D), the brain plays a crucial role in interpreting signals and sending commands to organs for adjustments.
