Mutant : T T A C A C
A.translocation
B.non-disjunction
C.frameshift
D.point
Answer:
d
Explanation:
that is an example of a point mutation. A point mutation is a mutation that causes only one nucleotide to change and in the example adenine changes to thymine
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.
Hence, the correct option is: D. Point mutation.

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 contribution to energy do carbohydrates make?
Answer:
Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

what is theory of to observe the neucles in cheek cells
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.

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

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

Explanation:
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.
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.

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?
If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.
What is the genetic disorder?A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.
Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

The genetic code for one amino acid molecule consists of A) five sugar molecules B) two phosphates C) three nucleotides D) four hydrogen bonds
Answer:
c
Explanation:
The genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.
What is genetic code?
Genetic code is defined as a sequence of instructions that directs the translation of DNA into 20 amino acids, which are the basic building blocks of proteins in living cells.
It can also be defined as the collection of instructions that live cells follow to convert information stored in genetic material into proteins.
Nucleotides are defined as a three-subunit chemical molecule consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group.
It can also be defined as the fundamental building component of nucleic acids.
There are basically two types of nucleotides.
Purines - They are defined as a heterocyclic aromatic organic molecule composed of two fused rings. Adenine, guanine and hydro xanthine are purines.Pyrimidine - They are defined as a simple aromatic compounds with a six-membered ring of carbon and nitrogen atoms. Cytosine, thymine and uracil are pyrimidines.Thus, the genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.
