Which of the following are narrow blood vessels that restrict blood flow and have thin walls that allow gas exchange? Alveoli Veins Arteries Capillaries.
Arterioles are narrow blood vessels that restrict blood flow and Capillaries have thin walls that allow gas exchange.
What is blood vessels?Blood vessels are channels that carry blood throughout your body. They help to transport oxygen to vital organs and tissues, and also remove waste products. Blood vessels include veins, arteries and capillaries.
Veins bring blood to the right side of your heart.
Arteries branch into smaller vessels called arterioles. Both arteries and arterioles are very flexible. They get bigger or smaller to help maintain your body's blood pressure.
Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.
thus, Arterioles are narrow blood vessels that restrict blood flow and Capillaries have thin walls that allow gas exchange.

Answer:
Capillaries
Explanation:
Capillaries are the tiniest vessels in the circulatory system. If the circulatory system is a network of roads, then capillaries are the side streets and alleyways that go to each building in a city. The majority of capillaries are so thin that blood cells must move through them singly. The thin walls of these confined tanks allow gas exchange.

An atom with 9 protons and 8 electrons is what kind of atom?
Hint: Cations have more positive charges than negative charges. Anions have more negative charges than positive charges. A neutral atom has the same number of positive charges to negative charges.
A
an anion
B
a cation
C
a neutral atom
Answer:
B. A cation
Explanation:
An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.
The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).
N.B: The cation atom will have a +1 charge

ATP is a cellular energy source to do every work, ATP is synthesized during cellular respiration to use this energy for cellular processes, hence option a is correct.
How does ATP is used?During photosynthesis, it is the synthesis of ADP to ATP using solar energy. In the mitochondria of a cell, the process of cellular respiration also leads to the creation of ATP.
ATP gets hydrolyzed into ADP or AMP and produces free inorganic phosphate groups in metabolic activities. Energy-wise, the conversion of ATP to ADP is beneficial, providing a Gibbs-free energy of -7.3 cal/mol.
A series of chemical reactions referred to as cell respiration convert glucose into ATP, which may then be utilized as energy for a variety of bodily functions.
Therefore ATP is broken down into ADP and releases energy to do work for cellular processes, hence option a is correct.

Hi friend! Hope you find this response helpful! :)
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
What is the role of camp in the signal transduction pathway activated by epinephrine?.
Answer:
When activated, adenylyl cyclase converts a large number of ATP molecules into signaling molecules, called cyclic AMP (cAMP). Because cAMP carries the message of the first messenger (epinephrine) into the cell, cAMP is referred to as a second messenger.
Explanation:
Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.
What is cAMP?Cyclic adenosine monophosphate, often known as cyclic AMP or cAMP, is a tiny, hydrophilic molecule that functions as an essential intracellular second messenger molecule that is controlled in a variety of physiological activities.
It is now understood that cAMP regulates cellular activity in all organisms, including amoebas, plants, and people. The biological functions of memory, metabolism, gene regulation, and immunity are all mediated by this second messenger.
Therefore, Adenylyl cyclase turns a large number of molecules of ATP into the signaling molecules cyclic AMP when it is activated (cAMP). cAMP is referred to as a second messenger because it delivers the signal of the first messenger (epinephrine) into cell.

-Are the Galapagos finches and people at the mainland equal species.
When Darwin visited the Galapagos islands he determined that the small flocks of finches that existed there have been very much like the finches that existed withinside the mainland of South America besides for his or her beak form and feeding habits.
• This brought about him to invite the query that 'Are the Galapagos finches and mainland finches the equal species?'
• Later on research made it glaring that some corporations of mainland finches migrated to the Galapagos island and occupied unique niches.
They adjusted themselves to the island surroundings and developed with new variations in beak shape and feeding habits.
• They at the moment are labeled into 14 corporations out of which thirteen exist withinside the Galapagos island.

How is the number of bonds carbon can make related to its ability to form molecules with many different shapes?
because each carbon atom can form four chemical bonds to other atoms and because the carbon atom is just the right or small size to fit in comfortably as parts of very large molecules.
The number of bonds carbon can make is related to its ability to form molecules with many different shapes because: it can form four (4) covalent bonds, rings, straight chains, and wrench chains.
Carbon refers to a non-metallic and tetravalent chemical element which is represented with the chemical symbol C and it has an atomic number (number of protons) of six (6).
Generally, carbon (C) has the ability to form chains that are almost unlimited in length because an atom of carbon can bond to other carbon atoms.
This ultimately implies that, carbon (C) can form molecules with many different shapes as a result of the number of bonds carbon it can make.
Hence, the ability of carbon (C) form molecules with many different shapes is simply because of the following:
Carbon (C) can form four (4) covalent bonds.It can form rings.It can form straight and wrench chains.Carbon (C) atoms can bond to other carbon atoms.Read more: https://brainly.com/question/17574947

How does apoptosis relate to cancer cells?
A. In cancer cells, too much apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
C. In cancer cells, apoptosis occurs only when cells grow without proper regulation.
D. In cancer cells, apoptosis occurs only when the cells receive the proper hormones.
Answer:
Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation
Many oncogenic stresses, including uncontrolled proliferation or DNA damage, trigger apoptosis; consequently, by culling cells at risk of transformation, apoptosis effectively prevents cancer. Apoptosis also suppresses tumourigenesis in various other ways.
The more malignant the tumour is, the more apoptosis shows. In this study, we propose a new theory that apoptosis plays a key role in the malignant progression and metastasis of cancer. The growth of tumour is the difference between tumour cell proliferation and attrition plus the hyperplastic growth of stroma.
