Which is true about water molecules?

A. Water molecules are nonpolar, meaning their charges balance each other out.

B. Water molecules are polar, meaning they have a net partial negative charge.

C. Water molecules are polar, meaning they have partial negative and positive
charges.

D. Water molecules are nonpolar, meaning they do not interact with each other.

Answers

Answer 1

Answer: C

Explanation: Water is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. Which is both positive and negative on opposite ends.

It could be B as well but, I believe it's C

the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.

Answers

Monosomy: the condition of having a diploid chromosome complement in which one chromosome lacks its homologous partner.

A trisomy is a chromosomal disorder characterized by an additional chromosome, so the person has 47 instead of 46.

Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2).

So, the correct answer is 'Monosomy'.

how do mitochondria generate and store the energy used to produce most of the atp made during aerobic respiration

Answers

Answer:
By generating a ionic (electrochemical) gradient

Answer:

The citric acid or Krebs cycle processes in the matrix of mitochondria produce a molecule called NADH. NADH is then converted to adenosine triphosphate by enzymes buried in the mitochondrial inner membrane (ATP). Energy is stored in the form of chemical bonds in ATP.

Explanation:

During aerobic respiration, how is ATP created in the mitochondria?

Oxidative phosphorylation produces the majority of the ATP produced by aerobic cellular respiration. By pumping protons across a membrane, the energy released by the O2 is utilized to create a chemiosmotic potential. This potential is subsequently used to activate ATP synthase, which converts ADP and phosphate groups into ATP.

What is the mechanism by which mitochondria store energy?

Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a tiny molecule that stores chemical energy created by mitochondria (ATP).

What is ATP's energy storage mechanism?

The energy currency of the cell is ATP, or adenosine triphosphate. It retains the energy created during cellular respiration when glucose is oxidized. Energy is stored in the form of high-energy phosphate bonds, which are broken to release energy. Energy is released when ATP is broken down into ADP and Pi.

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.

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.

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.

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 ^^
