A. The amount of Earth’s carbon is constant.
B. The amount of Earth’s carbon cannot be determined.
C. The amount of Earth’s carbon decreases.
D. The amount of Earth’s carbon increases.
I think its A
Answer:
Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year.
The model of the carbon cycle determines the amount of earth's carbon is constant. Thus, option A is correct.
Carbon is the element that is responsible for the major life forms on earth. The conversion of carbon in varying life forms and the reservoir is given by the carbon cycle.
What is the effect of the carbon cycle on the amount of carbon?The carbon cycle is operated for the analysis of the conversion of the carbon in different states and life forms in the earth.
The conversion results in the change in the state of the carbon and its concentration in different constituents.
The earth is the reserved closed system and is consisted of a fixed amount of elements.

The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle. What is a result of preventing spindle fibers from forming? Answer
A The cell cycle skips G1 phase
B Mitotic division is skipped, and the cell cycle proceeds to cytokinesis.
C Mitotic division stops in metaphase and cannot proceed to anaphase.
D The cell cycle skips S phase and proceeds to G2 phase.
Answer: the correct answer is C
Explanation:
Preventing the formation of spindle fibers makes the mitotic division stop in metaphase, and thus fail to proceed to anaphase.
• Colchicine prevents the polymerization of the microtubule, and thus, prevents the arrangement of the mitotic spindle, which shows the prevalence of another checkpoint in the cell cycle.
• As a result, the activity of the maturation promoting factor remains high, the chromosomes stay condensed, and the nuclear envelope fails to redevelop.
• A toxic effect is exerted on the living cells by the colchicine, which usually results in the arrest of the process of mitosis at an eventual stage, generally the metaphase, with the generation of unusual and bizarre nuclear configurations, and thus, resulting in the death of the cell.
Thus, the correct answer is option C.

The process of evolution, or genetic change over time, has resulted in the wide variety of living things that exist today. What part do mutations play in the evolution of species
Answer:
Evolution has occurred thanks to many random changes in the DNA base sequence that we call mutations. This is caused by errors in the genetic information contained in the cells - due to chemical or physical factors - and also its subsequent propagation by replication, being transcendent for evolution those that will later be transmitted to the offspring: somatic cells if reproduction it is asexual and the gametes if it is sexual. For this reason, we say that mutations are the primary source of gene variability, essential for evolution to exist. Thus, without mutations, the genetic variability that natural selection needs would not be present - in addition, such diversity is important for the population to more successfully mold (or adapt) to continuous environmental changes.
Explanation:
A mutation is a change in the information contained in the DNA of cells. The DNA of an organism influences all aspects of its life. Therefore, a change in the DNA of an organism can produce changes in all aspects of its life. The mutation increases the genetic variability of the species and contributes to the adaptation of the species to the environment and to their evolution. Viability and fertility are associated with adaptation, the total capacity of an organism to survive and reproduce. The effect of a mutation in any generation is minimal, but over time a considerable amount of variation from mutations can accumulate. Most mutations are harmful and their carriers die, but those that produce an improvement remain in the species and are essential in the evolutionary process. When mutations appear in a certain population, the genotype changes from generation to generation, appearing individuals with characteristics different from those of their predecessors. This is how the population evolves, being able to originate new species. Mutations that are detrimental to the carrier individual will be eliminated by natural selection.
Tim does not need to factor his amino acid consumption into the total protein intake because they are components of protein, not full protein
Answer:
Yes.
Explanation:
Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid into total protein.

Explanation:
Animals release _____ into the atmosphere through _____
Answer:
animal release carbon dioxide into the atmosphere through respiration
Explanation:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.
Animals breathe, taking in oxygen and releasing carbon dioxide. Animals release carbon dioxide gas into the outer atmosphere through respiration process.
What is respiration?
This process completes in two steps: external respiration and internal respiration. External respiration, or breathing, includes inhaling (inhalation) oxygen from the outside atmosphere and exhaling (exhalation) carbon dioxide to outside. In this process, gas exchanges take place at the lungs, and deoxygenated blood oxygenates before going back to the left heart.
In cellular respiration, the cell takes oxygen from the oxygenated blood and uses it in different cellular metabolic reactions, releasing carbon dioxide into the blood. So in cellular respiration, oxygen is taken up by the cell and carbon dioxide is released by the cell. This carbon dioxide goes to the lungs, and by the process of exhalation, it is released into the atmosphere.
Hence, animals release carbon dioxide into the atmosphere through the respiration process.

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
GranulationRecrystallizationMetasomatismMassiveFoliationFoliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.
If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.
What is a foliation?Foliation on a rock means continuous multi layering on a metamorphic rock.
These layers can be thin as a sheet of paper.
Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.
Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.
What is a resistance gene?In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.
Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.
