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
Explanation:
Which star has the greatest luminosity?
A)
Barnard's star
B)
Procyon
C)
Alpha Centauri
D)
Rigel
Answer:
c
Explanation:
Rigel, also known as Beta Orionis, is the star with the greatest luminosity. Therefore option D is correct.
It is a blue supergiant and one of the brightest stars in the night sky. Luminosity refers to the total amount of energy radiated by a star per unit of time.
Rigel's immense luminosity is a result of its massive size and high surface temperature. It is located in the constellation Orion and is approximately 860 light-years away from Earth.
Rigel's brightness and luminosity make it a prominent and significant celestial object, visible even to the eye, and it plays a vital role in the constellation's distinctive appearance.
Therefore option D is correct.

c) combines the isolated gene of one organism with the DNA of a different organism. (1 point)
Answer: Recombinant DNA is the correct answer
Answer:
Recombinant DNA
Explanation:
A cow has alleles for both black and
white fur that are codominant. What
would be the resulting appearance
of the cow?
A. a solid coat of gray fur
B. fur with areas of both black and white
C. it is impossible to determine
Answer:B
Explanation:
Codominant is when neither allele is recessive so they are both expressed in the phenotype
A cow having the codominant alleles for both white and black fur will appear to have fur with areas of both black and white fur. This is an example of co-dominance where both alleles are expressed in the different parts of the animal. So option B is correct.
What is codominance?In codominance, two different versions of a gene are expressed separately and they are expressed equally in different parts of the organism. As a result, the traits of both alleles are expressed simultaneously. The term co-dominant means that both alleles are dominant and one allele does not mask the expression of the other.
Co-dominance can easily be spotted in plants and animals. Codominance is observed in some traits that are less visible like blood type. The A and B alleles are codominant and they can be expressed simultaneously.

What is energy?Energy is the quantifiable attribute that is transferred to a body or a physical system in physics. It is observable in the production of work as well as in the form of heat and light. Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy.
The following is accurate regarding the magnets at issue: "While the magnets are kept separated, their kinetic energy and velocity are both at zero, but when they're let go and move together, they both quickly increase. The magnetic field's ability to retain energy declines."
The magnetic field's energy remains constant when a magnet is brought close to a rubber band. In the fourth question, kinetic, thermal, and gravitational energy are formed from some of the energy that has been stored.
Therefore, Drop two more magnets on the top of the stack and observe whether or not the interaction between magnet 1 and 2 changes. Thus, option A is correct.

Mutations occur randomly
A. True
B. False
Answer:
A true hope it's right can i get a brainliest plz
Explanation:
Answer:
Mutations occur spontaneously in all living things. By changing the chemistry of the organism's genetic material or altering the structure of a chromosome a mutation changes die structure or function of the organism and its offspring. Most often the mutation is harmful, and the change is erased by natural selection.
A central tenet in evolutionary theory is that mutations occur randomly with respect to their value to an organism; selection then governs whether they are fixed in a population.
Factors in the environment are thought to influence the rate of mutation but are not generally thought to influence the direction of mutation. ... In this respect, mutations are random — whether a particular mutation happens or not is generally unrelated to how useful that mutation would be.

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.
