Which two layers are approximately the same age?
core sample 1
core sample 2
Complete question:
Examine the following diagrams. Columns I and II contain rock layers A, B, C, D, E, and F. Both columns were taken from the same dig site at different locations. Which two layers are of approximately the same age? (Note: The diagrams are attached).
Answer:
C and D
Explanation:
Layers C and D apparently contain the same fossilized organisms in the same substrate. Their appearance is very similar. By knowing that certain organisms used to live in a certain period of time, if we find two strata that show the same fossilized organisms, then we can estimate that these two strata are the same age. Fossilized organisms are used to estimate the age of a rocky stratum.
Life history can be illustrated through fossilized organisms trapped or converted into rocks. These fossils are known as index or guide fossils, of animal or vegetal nature, and they can apport information about the rocky stratum in which they are located or incrusted. These fossils are used to determine the age of the rocky sediments or the environmental conditions under which they were deposited.
Answer:both of them are

By 1884, extensive hunting reduced the number of Northern elephant seals to fewer than 100. The extremely limited genetic variation in these seals is consistent with which genetic effect?
Answer:
Genetic drift, specifically the Bottleneck effect.
Explanation:
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
The bottleneck effect is a special case of genetic drift, which is most likely to affect smaller populations. In the exposed example, extensive hunting reduced the number of Northern elephant seals, reducing the number of individuals to fewer than 100. This population experienced one or many generations of very small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered, but the genetic pool might have not.

Which statement best answers the question, "Why is copper a good conductor of electricity?"
Copper atoms have a loosely held electron in their outer shell that is able to move freely to other atoms.
Copper atoms are tightly bound and are able to work with other copper atoms to exchange electrical charges.
Copper has an equal number of protons and electrons making the flow of current possible.
Copper's outer shell electrons are not balanced and must join with other copper atoms in order to be stable.
Answer:
option 1 is correct
Explanation:
the ability of substance to conduct heat and electricity depends upon the number of free electron since copper is transition metal it has a loosely held electron in their outer shell that is able to move freely to other atoms because of these free electron copper is a good conductor of electricity
The field of inquiry that studies human culture and evolutionary aspects of human biology; includes cultural anthropology, archeaology, linguistics, and physical, or biological anthropology. __________
Answer:
physical, or biological anthropology.
Explanation:
When there is a need to study human kind through the X-ray of relationships between human biology, its cultural diversity, and evolution ,the aspect anthropology for this is Biological anthropology.
Therefore biological anthropology is concerned about how the interaction between the cultural diversity and biological process results in the adaptations of mankind to different environments.The influence of these on growth, behaviours, existence.
The primary focus of biological anthropologists is to study in details the concept of ,mechanism of variation, adaptation.and how these lead to evolution and origin of mankind.
Sequel to this ,most evidences for this concept are obtained from the study of fossil materials,study of other related primates to man, and components of functional biology and genetics.

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.
Answer:
D
Explanation:
The correct option would be therapeutic cloning.
First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.
Artificial clonings are of different types, namely:
Reproductive cloningGene cloningTherapeutic cloningReproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.
Correct option: D
Why are so many of the same genes found in almost all living organisms
Answer:
Molecular homology occurs when different species inherit similar molecules, such as nucleic acids or proteins, from an evolutionary common ancestor. In many cases, especially for essential housekeeping genes involved in protein synthesis or DNA replication, genes are homologous across most, if not all, living organisms. Hope this helps!

Which of the following groups could be identified using the biological species concept? Select all that apply. Select all that apply. bacteria living today extinct dinosaurs sunflower species living today lizard species living today
Answer:
Bacteria, Sunflowers, Lizards.
Explanation:
They are all biological species due to being apart of flora and fauna. It wouldn't be dinosaurs since biologists study living things, dinosaurs are extinct.
The groups 'sunflower species living today' and 'lizard species living today' could be identified using the biological species concept.
The biological species concept defines a species as a special group of interfertile individuals.These individuals can then cross in order to produce fertile offspring and thus perpetuate the species.The biological species concept was developed by the biologist Ernst Mayr.In conclusion, the groups 'sunflower species living today' and 'lizard species living today' could be identified using the biological species concept.

Suppose you want to make a new connection to species in the concept map. Which of the terms below could fill in the blank in this new connection: "_____ is a mechanism that defines the separation between species." Select all that apply.
Answer:
Hello. You did not enter answer options, but some terms that can be used to fill in the blank are:
Hybrid infertility, Hybrid inviability, Behavioral isolation, Sympatric isolation, Habitat isolation, Hybrid breakdown, Allopatric isolation.
Explanation:
All of the above terms represent situations that cause separation between species. This separation can occur physically or molecularly, but it always results in genetic modifications that end up separating one species genetically from the other, causing evolution and generating different species, to the point that it is not possible to establish mating between its members.

During genetic engineering, how do Restriction enzymes know what base pairs to act on? A. Ligase bonds it to the correct spot. B. They don’t, the scientist must target it manually. C. They bond to the Recognition site. D. It recognizes the sticky ends.
Answer:
C
Explanation:
Restriction enzymes, also known as restriction endonucleases or DNA-cutter identify the base pairs to act on by targeting and binding to the recognition site in a gene.
The recognition site in a gene/DNA consists of four to eight palindromic nucleotide sequence. It is a region that the restriction enzyme cuts during the genetic engineering process in order to produce sticky or blunt ends. A gene might contain more than one recognition site.
Restriction enzymes are usually found in prokaryotic organisms, especially bacteria where they function primarily as defense molecules against bacteriophages.

What do enzymes do? Please answer real quick
Answer:
Catalyze biochemical reactions.
Explanation:
Hello,
In this case, it is widely known that enzymes are able to take substrates or reactants to their active sites, in order to catalyze a raft of biochemical reactions by which products that are not usually formed under typical conditions are formed, and then allow them to dissociate from the surface of the enzyme. Such combination formed by an enzyme and its substrates is called the enzyme–substrate complex which is further taken to the isolated product.

What is Ependymal cell?
Answer:
Explanation: Ependymal cell is a type of neuronal support cell the forms the epithelial lining of the brain ventricles in the brain and the central canal of the spinal cord ependymal cells similar to all other neuroglia, are derived from a layer of embryonic tissue known as neuroectoderm.
Ependymal cells are ciliated-epithelial glial cells. It develops from radial glia alongside the surface of the ventricles of the brain and spinal canal.
What is the function of Ependymal cells?The main role of Ependymal cells is formation of CSF.
The CSF refers to cerebrospinal fluid. It is done by movement of sodium ion, chlorine ion and bicarbonate ion from blood to ventricles of brain.
Inside ventricles of the brain, collection of ependymal cells and capillaries together i.e., the tela choroidea form choroid plexus, which produces the CSF.
Thus, Ependymal cells are involved in formation of CSF.
