Explain why scientirsts concluded that the instructions for species characteristics were carried in DNA.
Answer:
Explanation:
Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.
DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.

hope this helps (:
The mutation shown here is point mutation.
What is mutation?"A changes/alteration in nitrogenous bases sequence of DNA that can results in changes in the genotype and phenotype of an organism is known as mutation."It occurs due to: deletion, insertion, translocation and inversion.During insertion, an extra nitrogenous bases are added to the DNA sequence.During deletion, a nitrogenous bases are removed from the DNA sequence.During inversion, the sequence of nitrogenous bases gets inverted in a DNA strand.In translocation, a sequence of one DNA strand breaks off and attaches to another DNA strand.What is point mutation?"A point mutation occurs in a genome when a single base pair is added, deleted or changed."Here, the sequence of original strand is A T A C A C and the sequence of mutant one's is T T A C A C. The base A is changed into base T.

5 facts about the L.A. flood of 1938
I will give you all my points!
Answer:
1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.
2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.
3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.
4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.
5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins

A car turns left while maintaining a speed of 20 m/s. Does the car’s velocity change? Explain your reasoning!
Answer:
Yes
Explanation:
Speed is a scalar quantity (only has a magnitude). It signifies the rate of change of an object's movement.
Velocity is a vector quantity that signifies the rate of change of movement but also the direction of an object's movement.
Since the car turns, its direction changes, so the velocity changes.
What causes ocean water to be colder at the poles than at the equator
Answer:
Ocean currents warmed by the Sun's energy carry heat from the equator toward the poles as well. Evaporation of surface water, rain and other precipitation, wind and ocean currents move warm air toward the poles and bring cold air toward the equator.

Some bacteria of the same species and genotype can reduce sulfur anaerobically for energy, depending on the environment. This
an example of...
A)growth and response
B)genotype mutation
C)phenotypic plasticity
D)inclusive fitness
Answer:
C) phenotypic plasticity
Explanation:
The ability of an organism to change phenotypically according to environmental conditions is known as Phenotypic plasticity.Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are metabolically versatile. They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.

Select the correct response regarding the relationship between photosynthesis and cellular respiration. a The reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration.
A. The reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration.
B. The products of cellular respiration are the reactants of photosynthesis.
C. The reactants of photosynthesis are the reactants at cellular respiration.
D. The products of cellular respiration are the products of photosynthesis.
The correct response regarding the relationship between photosynthesis and cellular respiration is option B. The products of cellular respiration are the reactants of photosynthesis.
Photosynthesis and cellular respiration are two essential processes in autotrophs. These processes are opposite to each other as photosynthesis is an anabolic and respiration is a catabolic process.
In photosynthesis, carbon dioxide and water are reactants that are combined to form glucose. Light energy is stored in chemical energy in this process. In cellular respiration, glucose is oxidized in presence of oxygen and produces water and carbon dioxide as products, and releasing ATP is released as the source of energy.Thus, the correct answer is - option B. The products of cellular respiration are the reactants of photosynthesis.

Which of the following best summarizes how hormone levels are controlled?
Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.
Hormones are controlled by oxygen levels; the internal environment maintains all systems, including endocrine functions.
Hormones are controlled by muscles; hormones are released when muscles contract and stopped when muscles relax.
Hormones are controlled by the nervous system; the spinal cord sends messages about hormone levels to the brain.

Answer:
You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.
Explanation:
I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.
