Temperature changes led CO2 changes
Methane played the dominant role in the warming and cooling
Plate tectonics played the dominant role in the warming and cooling
CO2 changes led temperature changes
Answer:
Explanation:
The history of humanity from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human bieings that we are today evoled from many years ago some say from the begining of time— it is connected to climate variation and change. Human biens has experienced nearly two full glacial-interglacial cycles, but its global geographical expansion, massive population increase, cultural diversification, and worldwide ecological domination began only during the last glacial period and accelerated during the last glacial-interglacial transition. The first bipedal apes appeared in a time of climatic transition and variation, and Homo erectus, an extinct species possibly ancestral to modern humans, originated during the colder Pleistocene Epoch and survived both the transition period and multiple glacial-interglacial cycles. Thus, it can be said that climate variation has been the midwife of humanity and its various cultures and civilizations.
Answer: involve rapid, nonlinear, reactions of ice volume, CO2, and temperature to external astronomical forcing. The precise timing of events may be modulated by millennial‐scale climate change that can lead to a contrasting timing of maximum interglacial intensity in each hemisphere. A variety of temporal trends is observed, such that maxima in the main records are observed either early or late in different interglacials. The end of an interglacial (glacial inception) is a slower process involving a global sequence of changes. Interglacials have been typically 10–30 ka long. The combination of minimal reduction in northern summer insolation over the next few orbital cycles, owing to low eccentricity, and high atmospheric greenhouse gas concentrations implies that the next glacial inception is many tens of millennia in the future.
1 Introduction—Interglacials of the Last 800 ka
Earth's climate of the last 800 ka (1 ka = 1000 years) is the latest stage in a slow cooling that has been in progress for the last ~50 Ma (1 Ma = 1 million years) [Zachos et al., 2008]. During this cooling, ice sheets formed on the Antarctic continent ~40 Ma ago, while the first signs of Northern Hemisphere (NH) glaciation appeared much more recently. Only at the start of the Quaternary Period and the Pleistocene Epoch, ~2.6 Ma ago, did alternations between cold glacial periods with ice on the NH continents, and warmer intervals with little or no NH continental ice, first appear, reflected in the appearance of ice‐rafted debris

Which of the following correctly describes distinguishing characteristics of the Kingdom Plantae?
O Photosynthtic and multicellular
O Vascular and flowering
O Prokaryotic and photosynthetic
O Terrestrial and eukaryotic
Photosynthtic and multicellular correctly describes distinguishing characteristics of the Kingdom Plantae.
What are the characteristice of kingdom Plantae?Kingdom Plantae includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis.
They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes.
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).

An important piece of information in the management of a person infected with a chronic virus such as HIV is his/her "viral load" or how many virus particles can be detected. If before PCR, a patient had a viral load of 1.6 x 104 viral particles. What would be the amount of DNA in the sample after the completion of the first PCR cycle?
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.

Which is the best choice for a genetic transformation: a bacterium, earthworm, fish, or mouse?
Answer:
A bacterium would be the best choice in this case
Explanation:
Bacteria are small, single-celled organisms which reproduce quickly and easily; it is made of only one cell, it reproduces every 20 minutes, it does not make people sick, it cannot survive outside the lab, etc.
Among the options given, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.
What is Transformation?Transformation may be defined as a process of horizontal gene transfer through which some bacteria take up foreign genetic material (unaided DNA) from the environment. This technique was first reported in Streptococcus pneumoniae by Griffith in 1928.
The population of bacteria utilizes three techniques in order to reproduce and permits genetic variations. They are conjugation, transformation, and transduction. Bacteria are small, single-celled organisms that reproduce quickly and easily in nature.
Transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from a surrounding atmosphere.
Therefore, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.

Explain why red blood cells can be maintained in an intact state by keeping them in a normal saline solution.
Answer:
The solution is isotonic.
Explanation:
Saline solututions are mixtures of salt and water. In a normal saline solution, red blood cells maintain their shape. This is because the saline solution is isotonic. Essentially it has the same concentration as inside the red blood cell.
The water does not move down a particular gradient, thus the shape remains unchanged.
Red blood cells can be maintained in an intact state by keeping them in a
normal saline solution because the solution is Isotonic.
Isotonic solutions possesses the same osmotic pressure or equal
concentration of solutes and this aids free movement of solute in and out of
the cell via the semi-permeable membrane.
The solution must be isotonic to enable the red blood cells remain intact
thereby preventing swelling or shrinking of the cells.

If a nucleus has eight chromosomes during interphase, how many chromosomes does it have after mitosis is complete
Answer:
8 chromosomes
Explanation:
Mitosis is the process whereby a cell divides into two identical copies of itself. This genetical identity emanates from the fact that the daughter cells possess the same kind and number of chromosomes as the parent cell.
Hence, a nucleus that has eight (8) chromosomes during interphase will possess 8 chromosome in each daughter cell at the end of mitosis. Mitosis, which consists of stages, duplicate its DNA at the interphase stage but do not increase the chromosome number. Sister chromatids are formed for each chromosome, which separate during anaphase stage, and become individual chromosome in each daughter cell.
In this case, 8 chromosome are still formed at interphase but 16 sister chromatids. These chromatids separate equally into each daughter cell i.e 8 in each cell to become individual chromosomes.
