There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.

During fermentation, how do changes to a molecule of pyruvic acid to lactic acid or ethyl alchol contribute to
the formation of ATP?

Answers

Answer:

Some organisms, such as some bacteria, will undergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt.

I. mitosis

J. sex cells

Explanation:

In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

1.What is unique about the reflex behavior?

The messages never reach the central nervous system

It originates in the spinal cord, not the brain

It is localized in the cerebellum instead of the cortex

It only uses the autonomic nervous system

2.The peripheral nervous system is made up of:

The sympathetic and parasympathetic systems

The autonomic and somatic systems

The environment and sensory receptors

The brain and spinal cord

3.Which of the following behavior would be associated with the SOMATIC nervous system?

Breathing during sleep

Heartbeat

Scratching an itch on your head

Sweating

4.In regards to the Autonomic nervous system, Sympathetic is to Parasympathetic as:

Automatic Behaviors: Voluntary Behaviors

Calms you down; Reacts to threat

Voluntary Behaviors

Reacts to a threat; Calms you down

5.Sensory nerves that carry information from the environment and bring it back to the the Central Nervous System are part of the

Sympathetic Nervous System

Parasympathetic Nervous System

Somatic Nervous System

Autonomic Nervous System

Answers

Answer:

The thing that is unique about the reflex of behavior is it is involuntary and almost instantaneous reaction to a stimulus. Take plants for an example. Their stimuluses are tropisms. Phototropism is a reaction to a light source in order to achieve photosynthesis. Hydrotropism is a plant's reaction to a nearby water source, in which the plant's roots grow towards it. Geotropism is a plant's reaction to gravity, in which the plant's roots grow down, and the stem grows up.

The peripheral nervous system is made up of The brain and spinal cord.

The behavior that would be associated with the SOMATIC nervous system is scratching an itch on your head.

In regards to the autonomic nervous system, sympathetic is to parasympathetic as calms you down; reacts to threat.

Sensory nerves that carry information from the environment and bring it back to the central nervous system are part of the autonomic nervous system.

Answers

Answer: Prokaryotic cells have free flowing DNA. This DNA is in a circular shape and flows freely in the cytoplasm

Answer:Prokaryotic cells

Explanation:

Prokaryotic cells as well as bacteria have a free-floating chromosome that is normally circular and is not enclosed in a nuclear membrane instead The DNA simply lives in a region of the cell called a nucleoid.Prokaryotic cells only have a small range of organelles, normally  only a plasma membrane and ribosomes

What is a Prokaryotic cell?

Prokaryotic cells comprise bacteria and archaea. They Normally  have a diameter of 0.1–5 μm, and their DNA is not contained within a nucleus. alternatively , their DNA is circular and can be located  in a region called the nucleoid, which floats in the cytoplasm

What is a body function that would contribute to BMR?
Breaking down a burger in the stomach
O Catching a Frisbee
O Heart beating
O Wrestling a Grizzly Bear

Answers

Answer:

Breaking down a burger in the stomach.

Explanation:

Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.

This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.

Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.

Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
