Explain the relationships between dehydration synthesis, hydrolysis, monomer, and polymer

Answers

Answer:

combine with each other using covalent bonds

Explanation:

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Answer:

Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct.  Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.

How do human beings affect the carbon dioxide and oxygen cycle?

Answers

Answer:

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.

Answer:

By breathing.

Explanation:

Humans inhale oxygen, and when they need to release it, (exhale) that oxygen is no longer oxygen and is now carbon dioxide. Trees and plants are what helps oxygen to exist in our world even though we breathe it in and convert it to carbon dioxide. Hope this helps ^^

please help me with insects with out piercing and sucking mouth parts and the reason why. please help me I really request.​

Answers

Answer:

Insects have a range of mouthparts, adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Specialization has mostly been for piercing and sucking, although a range of specializations exist, as these modes of feeding have evolved a number of times (for example, mosquitoes and aphids (which are true bugs) both pierce and suck, however female mosquitoes feed on animal blood whereas aphids feed on plant fluids. In this page, the individual mouthparts are introduced for chewing insects. Specializations are generally described thereafter.

The ________, which stains dark as it contains pigments and blood vessels, is just underneath the retina.

Answers

The choroid stains dark as it contains pigments and blood vessels. It is

located underneath the retina. It  also lies between the retina and the sclera.

The choroids are very rich in connective tissues( blood vessels) which help

supply the retina with vital nutrients needed for proper eyesight.

The choroids are usually thickest at the extreme rear end of the eye and also helps to maintain a constant eye temperature and volume. This is

important to prevent changes in eye size and temperature which may cause

i got the answers off a quiz let

At the most basic level, schizophrenia is best conceptualized as a neurodevelopmental disorder.

It is characterized by a complex interplay of genetic, environmental, and neurobiological factors that disrupt brain development and function during early stages of life.

While the exact causes are not fully understood, research suggests that abnormalities in brain structure, neurotransmitter imbalances, and genetic predisposition contribute to the onset of schizophrenia.

These disruptions may affect cognitive processes, emotional regulation, and perception, leading to symptoms like delusions, hallucinations, disorganized thinking, and social withdrawal.

Understanding schizophrenia as a neurodevelopmental disorder highlights the importance of early detection, intervention, and holistic treatment approaches to improve outcomes and quality of life for individuals affected by this condition.
