Select all of the answers that apply. Four laws or principles are involved with the study of stratigraphy. They are _____. 1 law of original horizontality 2 law of superposition law of original lateral continuity 3 law of gravity and oppositional force 4 law of cross-cutting relationships
Answer:
Option (1), (2) and (4) are the correct
Explanation:
According to the Steno, the four laws that deals with the study of stratigraphy are as follows-
Law of Superposition- this law states that in a geochronological sequence the rock layers that are present at the top are the youngest and the rock layers that lies at the bottom are the oldestLaw of Original horizontally- this law states that the sediments usually gets deposited in a horizontal manner due to the influence of gravityLaw of Cross-cutting relationship- this law states that in a particular area when the igneous bodies (such as batholith, plutons etc) intrudes other rocks, then these intruding features are generally younger than the rocks which it cuts, maintaining a cross-cutting relationshipLaw of lateral continuity- this law states that the the sediments at first are deposited and extended laterally in every direction until they meet another geological feature that interrupts its path of lateral extensionWhich process MUST occur before mitosis and meiosis can occur?

Which experiment is most likely to have reliable results? A. An experiment that proves the hypothesis B. An experiment in which there are no controls C. An experiment that confirms predictions D. An experiment in which the outcome is repeatable
Answer: D. An experiment in which the outcome is repeatable
Explanation:
An experiment is performed by utilizing a suitable methodology. The correctness of the methodology is analyzed by repeating a process several times so as to obtain concordant readings. Similarities in such readings with subsequent attempts will make the methodology as well as the outcomes of the results valid.
On the basis of the above explanation, D. An experiment in which the outcome is repeatable. is the correct option.
In the body, lipids _____.
a. contribute to proper body hydration
b. stimulate the production of vitamins and minerals
c. help maintain cell membranes
d. are necessary for the absorption of dietary fiber
Answer: help maintain cell membrane
Explanation:
Photosynthesis true or false increasing light intensity decreases rate of photosynthesis
In Photosynthesis, as the intensity of light increases, the rate of photosynthesis also increases. Thus, the given statement is a false statement.
What is Photosynthesis?Photosynthesis is the process of formation of sugar (carbohydrate) in the chloroplast of leaf of the plants. The chlorophyll pigment present in the chloroplast are responsible for trapping sunlight into the cell, this facilitates the process of photosynthesis.
The rate of photosynthesis is the amount of carbohydrate formed and oxygen released with respect to change in time. The rate of photosynthesis depends upon factors like light intensity, wavelength, etc. The rate of photosynthesis is directly proportional to the intensity of light.
Therefore, the given statement is false.

The upper limit of the zone of saturation is called _____.
the water table
the zone of aeration
an aquifer
a spring
The right option is; the water table
The upper limit of the zone of saturation is called the water table.
Water table is the top level of an underground surface where the rocks or pores of the ground are indelibly saturated with water. The water table removes the zone of aeration that is situated on top of it from the groundwater zone that is situated beneath it. Certain conditions such as amount of precipitation used by plants, climatic differences, and withdrawal of large amounts of water from wells, affect the water table and make it to fluctuate both with the seasons and from year to year.
Answer:
A. The Water Table

A proteins is a sequence of amino acids, which is coded for by sequences of dna. what specific part of a dna sequence codes for the amino acid sequence?
A protein is a sequence of amino acids which are coded by the sequence of DNA present in the nucleus of cell. The codes are in the form of codons which is made up of three nucleotide bases each.
What are codons?
Proteins are the building blocks of body. The process of formation of proteins takes place in the ribosome of cell and this process is known as translation. They are formed by the polymerization of amino acids into the form of long chains of polypeptides which undergoes post-translational modifications to form a functional protein.
Codons are the sequence of three nucleotide bases or triplets which codes for specific amino acids as well as stop codons. These codons are the sequence of nucleotides present in the DNA of the cell.

How do evolutionary psychologists use natural selection to explain our human behavioral tendencies?
Answer:
Evolutionary psychologists seek to understand how natural selection has shaped our traits and behavior tendencies. The principle of natural selection states that variations increasing the odds of reproducing and surviving are most likely to be passed on to future generations. Some variations arise from mutations (random errors in gene replication), others from new gene combinations at conception. Charles Darwin, whose theory of evolution has for a long time been an organizing principle in biology, anticipated the contemporary application of evolutionary principles in psychology.
Evolutionary psychologists use natural selection to explain the human behavioral tendencies shaped by natural selection, as the genetic variations increases the odds of reproduction in organisms and survival of the future generations.
