Answer:
The Uniqueness of Carbon
Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms.

Which of the following would provide the best assessment of the parent material of the soil
- O horizon
- A horizon
- B horizon
- D horizon
Answer:
The correct answer is B
Explanation:
It may be made of the same mineral material that the more superficial layers were formed from, or it may be made of a distinct complex of minerals, rock forms the D horizon, hence option D is correct.
What is the parent material of the soil?An unweathered soil layer that can occasionally be found below the B-horizon or the C-horizon, if they are present.
The soil you see above this rock is made of rock that has weathered (unless the soil has been deposited from elsewhere eg floodplains contain soil that has been carried downstream in water and then deposited as the flood recedes).
Therefore, bedrock's D Horizon - Rock that has been solidified makes up this stratum (tight, unbroken, large formations of rock). Roots do not penetrate thus far down, and there is very little organic matter.

Answer:
The stroke volume value (X) in the table is 54 cm³.
Explanation:
Stroke volume (SV) is a value that depends on the amount of blood the heart pumps in one beat, that is, during left ventricular systole.
If the cardiac output (CO) is obtained from the stroke volume and the heart rate (HR), the stroke volume can be calculated with the known CO and HR data:
CO = SV X HR
Clearing the formula:
Stroke Volume = CO / HRStroke Volume = 2800 cm³.min ÷ 52 bpm Stroke Volume = 53.85 = 54 cm³.The stroke volume value when the CO is 2800 cm³.min and HR is 52 beats per minute corresponds to 54 cm³.

4. Bacteria can share genetic information with each other. How does this make it more difficult to design medications that attack bacterial colonies? (4 points)
Explanation:
Genetic exchanges among bacteria occur by several mechanisms. In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.
Genetic information in bacteria and many viruses is encoded in DNA, but some viruses use RNA. Replication of the genome is essential for inheritance of genetically determined traits. Gene expression usually involves transcription of DNA into messenger RNA and translation of mRNA into protein.
Answer:
The bacteria shares information with the recipient, making it harder to differentiate between the bacteria, and the host.
Explanation:
It mates with the recipient's cells and transfers genetic information. Since bacteria is living, it can share this to the host, making it less recognizable. This would make it more difficult to target only the bacteria.

Which three organs help a plant carry out photosynthesis?
Answer: B, C, and D.
Explanation: Leaves absorb the light coming from the sun. Leaves also have something included in them called chlorophyll. Plants use this chlorophyll and light for photosynthesis. The stem helps to transport the products of photosynthesis. The roots absorb some of the most important nutrients to a plant.
Three organs that help a plant carry out photosynthesis are the leaves, by trap sunlight and take in carbon dioxide, and the stem, which transports nutrients and water to plant cells.
What is photosynthesis?Photosynthesis is a chemical process by organisms that contain chlorophyll to make their own food. The process includes light, carbon dioxide, water, and chlorophyll.
Thus, the correct options are B and C.

Describe three environmental considitons that increase the rate of transpiration in plants, explaining how they operate:
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.

Which best describes the law of independent assortment?
A. Traits can only be controlled by a single gene.
B. The traits of the F2 generation are random.
C. The traits of an offspring are independent from the parents.
D. When sex cells form, alleles of a trait separate independently.
Answer:
D. When sex cells form, alleles of a trait separate independently.
Explanation:
i got it right on the test
According to the law of independent assortment, during the formation of gametes, the separation of traits occurs independently. So option D is correct.
Segregation is the principle that each individual has two alleles, and only one of those alleles is inherited by the progeny. Independent assortment is the principle that the genetic makeup of one pair is independent of the genetic makeup of another pair.
Each gene comes in different versions, called alleles. The dominant allele hides the recessive allele, which determines the appearance of the organism. When an organism creates gametes, only one gene copy is selected at a time. This is called the law of segregation.

15. Will the asteroid belt be able to coalesce into a 9th planet with the current configuration
of the solar system?
I
Answer:
No.
Explanation:
No, the asteroid belt is not able to unite into a 9th planet because there is not enough total mass in the belt to form a planet. the other reason is that the belt is too close to Jupiter which make impossible to make the asteroid belt a planet. When this formation of new planet happens between the asteroid and Jupiter, Jupiter's gravitational forces act on the asteroid add up and strengthen each other, and they can easily kick the asteroid out of the solar system.
