The tropical rain forest biome has some of the highest biodiversity on earth how would a decrease in the biodiversity due to deforestation or other factors affect the large biosphere
Answer:
Negatively.
Explanation:
A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
The decrease in biodiversity due to deforestation and other factors in the tropical rainforest biome will negatively affect the biosphere. Thus, the effect will be negative.
What is the biosphere?The biosphere also called the ecosphere is the sum of the total life or the ecosystem. It includes the part of the planet where life is inhabitants. It may include a mountain, roots, dessert, oceans, etc. It is interrelated to biodiversity.
If the biodiversity of a place gets declined due to factors like deforestation, pollution, poaching, natural disasters, etc. then it will affect the ecosystem. If the stone species are lost then it will have a detrimental effect on the ecosystem.
These negative consequences disrupt the food chain and will result in affecting every organism. This chain of disruption will cause an overall loss to the biosphere.

How does deforestation affect coral reefs?
Answer: When the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs. That runoff adds nutrients to the ocean water.
Explanation: Basically, when this occurs, the roots are no longer attached to the soil, letting all the nutrients get ruined in the ocean water instead of feeding plants/animals/trees.
whats the difference between aerobic and anaerobic respiration
Answer:
Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.

Answer:
DNA has 2 strands and mRNA has 1 strand of nucleotides.
DNA has 2 strands and mRNA has 1 strand of nucleotides.
Deoxyribonucleotides is simply referred to as the fundamental (basic) unit of a deoxyribonucleic acid (DNA).
Basically, deoxyribonucleic acid (DNA) comprises two (2) strands of nucleotides which are arranged in a double helix.
On a related note, a messenger ribonucleic acid (mRNA) refers to a molecule that is complementary to the template strand of deoxyribonucleic acid (DNA).
Hence, mRNA has one (1) strand of nucleotide and it is mainly used for the encoding of protein molecules.
In conclusion, deoxyribonucleic acid (DNA) has two (2) strands of nucleotides while messenger ribonucleic acid (mRNA) has one (1) strand of nucleotide.

What will happen to the pressure in the brain if water moves into it from the blood?
Answer:
A sudden increase in the pressure inside a person's skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery
Explanation:
A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.
What is brain?The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.
There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath.
It is possible for patients with elevated ICP to fully recover with prompt treatment.
Therefore, A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.

What is cellular respiration ?
A series of chemical reactions known as cellular respiration break down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation. The citric acid cycle takes place in the mitochondrial matrix, glycolysis takes place in the cytosol, and oxidative phosphorylation takes place on the inner mitochondrial membrane. Glucose, ATP, and NAD+ are the cellular respiration starting reactants, the rate-determining enzymes for cellular respiration are phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase, and the final products include ATP and water. One or more enzymes involved in cellular respiration, like succinyl-CoA-synthase or pyruvate kinase, are typically disrupted by diseases that affect this process.Glycolysis is the only process that can take place without oxygen, and only two ATP molecules can be produced for each glucose molecule. ATP and H2O are the two final end products of cellular respiration. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH molecules, and two H2O molecules.One acetyl-CoA, one NADH, and one CO2 are produced for each pyruvate molecule when oxygen is present. One GTP, three NADH, one FADH2, and two CO2 are the products of the TCA cycle. GTP is an energy-rich compound similar to ATP that is typically used in environments with lower pH. The electron transport chain can then use NADH and FADH2 to make more ATP as part of oxidative phosphorylation.

I hope this helped and was explained better
The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
What is the corresponding action?The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.
Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.
All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.
Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.

In passive transport, molecules move__ the concentration gradient.
Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.

What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor in the cell such as oxygen to produce large amounts of energy, to drive the bulk production of ATP (Adenosine triphosphate) in the mitochondria.
A large number of folds are present in the mitochondrial membrane to increase the capacity of the mitochondrion to synthesize ATP molecules, the inner membrane of the mitochondria is folded to form cristae in the membrane. These folds allow a much greater amount of electron transport chain (ETC) enzymes and ATP synthase to be packed into the mitochondrion membrane.
