Determine the direction of blood flow through the chambers, vessels and valves of the heart and lungs. Summarize your findings below beginning with oxygen-poor blood from the body entering the heart and ending with oxygen-rich blood leaving the heart to re-supply the body. 1 Vena cavae (vessels) 8 (vessels) 2 Right atrium (chamber) 9 (chamber) 3 (valve) 10 (valve) 4 (chamber) 11 (chamber) 5 (valve) 12 (valve) 6 (vessels) 13 (vessels) 7 Through the lungs (O2 picked up) 14 Through the body (O2 released)
Answers
Answer:
1 Vena cavae (vessels)
2 Right atrium (chamber)
3 Tricuspid valve (valve)
4 Right ventricule (chamber)
5 Pulmonary valve (valve)
6 Pulmonary artery (vessels)
7 Through the lungs (O2 picked up)
8 Pulmonary veins (vessels)
9 Left atrium (chamber)
10 Mitral valve (valve)
11 Left ventricle (chamber)
12 Aortic valve (valve)
13 Aorta (vessels)
14 Through the body (O2 released)
Explanation:
The oxygenated blood travels through the arteries distributing oxygen to the cells. Then the deoxygenated blood goes through the veins and to the heart and the lungs.
The deoxygenated blood enters the heart through the vena cavae. From there, it goes to the right atrium. The accumulation of blood in the right atrium opens the tricuspid valve, and the blood goes to the right ventricle. Between the right ventricle and the pulmonary vein, it is the pulmonary valve. The valve stops blood from going back to the ventricle once it is in the pulmonary artery. The pulmonary artery carries the blood to the pulmonary arterioles and these to the pulmonary capillaries, where the blood picks up oxygen and releases carbon dioxide. This process happens in the lungs.
Once that the blood has oxygen, it goes from the capillaries to the pulmonary venules. Then, to the pulmonary vein. The pulmonary vein brings the blood to the left atrium, then it goes through the mitral valve and flows to the left ventricle. Between the left ventricle and the aorta, it is the aortic valve. A valve that stops the blood from going back to the ventricle once it went to the aorta. From the aorta, the oxygenated blood goes to the rest of the body.
The element carbon has multiple bonding patterns. Which bonding pattern cannot be formed by carbon?
A. CC
B. C-C-C
C.C.C.C
D. C=C=C
Answers
Answer:
D
Explanation:
Because there is only one carbon it says they are equal
A. CC and C. C.C.C
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.A carbon atom can form the following bonds:
Four single bonds. One double and two single bonds. Two double bonds. One triple bond with one single bond.In options, B and D there are single and double formation between carbon atoms. Thus these are correct bonding patterns.
Therefore, bonding pattern cannot be formed by carbon is option A and C.

leaves accumulates less Food than non-varigated leaves under similar condition
Answers
Answer:
Due to less number of chlorophyll.
Explanation:
The variegated leaves accumulates or produces less amount of food than non-variegated leaves under similar condition because variegated leaves has number of chlorophyll as compared to non-variegated leaves. Chlorophyll is a green pigment that is responsible for the photosynthesis in plants, without chlorophyll no photosynthesis occurs in the plants. The variegated leaves has less number of chlorophyll as compared to non-variegated leaves which leads to less production of food in variegated leaves.

Bumblebees show some ability to control their own body temperature. During cold weather, bumblebees have been observed warming their flight muscles by shivering. The bees are able to maintain a body temperature several degrees above that of the surrounding air. Regulation of their internal body temperature is an example of A. diffusion B. synthesis C. respiration D. Homeostasis
Answers
Answer:
D. Homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Hence, regulation of the internal body temperature of the bumblebee is an example of homeostasis.

6. a) In what way is the genetic code in all organisms the same? (1 point)
Answers
Answer:
they all come from the same ancestor, and all organisms have DNA made of the same molecules that form our genetic code. DNA in every organism has the bases: A,T,C,G.
Also, don't use this if it's still June 2021 and you're doing ap ex, we might have the same teacher.
All living organisms use the same genetic code. This shows that all organisms share a common evolutionary history.
What is a genetic code ?The genetic code is the set of rules used by living cells to translate information encoded within genetic material into proteins. It is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis.
The genetic code is universal. Living systems use nucleic acids and the same three-base codons to direct the synthesis of proteins from amino acids. For example, the mRNA codon UUU, codes for phenylalanine in all cells of all organisms.To know more about genetic code here

As a scientific concept, race Group of answer choices A. is very significant because it gives us a clearer understanding of human behavior than the concept of culture provides. B. is evidenced by the exclusive possession of particular types of genes. C. aids in explaining human diversity. D. is not very significant because it gives us little insight into human behavior. E. Both B and D
Answers
Answer:
D. is not very significant because it gives us little insight into human behavior.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
As a scientific concept, race is not very significant because it gives us little insight into human behavior.
This ultimately implies that, race is a scientific concept that holds no significant or absolute value since the nineteenth century.
Hence, the difference between humans shouldn't be described based on race according to the United Nations Educational, Scientific and Cultural Organization (UNESCO).
Gene mutations can be caused by many things. These mutations are biologically important because they
can be passed to the offspring if they occur in any cell of the body
can result in a new variety of gene combinations in the species
are always harmful and therefore help to eliminate weak traits
occur at a regular rate and therefore can be controlled
Answers
Answer:
Can result in a new variety of gene combinations in the species
Explanation:
The third option is blatantly untrue- gene mutations are sometimes harmful, usually mundane and do nothing, and sometimes extremely helpful.
The fourth option is also untrue- genetic mutation is completely random.
This leaves us with the first two-
The first option is true, but it's not why genetic mutations are important, it's simply how they are passed on.
The second option is the awnser because gene diversity is extremely important in populations, and 'variety of gene combinations' is just another way to say gene diversity.
