Explanation:
What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
The gecko is a reptile that has the amazing ability to climb smooth surfaces - even glass. Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. When not selling car insurance, geckos climb smooth surfaces.
a. How is this method of stickiness advantageous to the gecko over covalent interactions?
b. Given that van der Waals forces are among the weakest molecular interactions, how can the gecko's feet stick so effectively?
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.

Why is diffusion such an efficient process
for all cells?
A. It does not require energy.
B. It occurs so quickly.
C. The high amount of energy used during diffusion is offset by
the amount it creates.
Answer:
A.
Explanation:
Diffusion does not require energy. It's depends on the concentration gradient of the two molecules.
Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the migration of substances from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.
Diffusion does not require any type of energy for the movement of ions, molecules, or substances. It is a very feasible form of migration of substances.
Diffusion is a type of passive transport and hence takes place in a dropping manner without any expenditure of energy.
Therefore, Diffusion is such an efficient process for all cells because it does not require energy. Thus, the correct option is A.

Which of the following is an example of selective breeding?
A. Breeding tomatoes to increase fruit size
B. Crossing 2 plants w desirable traits
C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat
Answer:
b
Explanation:
they chose the best tomatoes to make even better ones
Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.
Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.
In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.
This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

Hydrogen bonding is primarily responsible for the high ______ of water.
a. freezing point
b. boiling point
c. conductivity
d. polarity
The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds
Explanation:
Therefore, option b is correct.Hydrogen bonding is primarily responsible for the high boiling point of the water. Thus, the correct option is B.
What is Hydrogen bonding?Hydrogen bonding is an interaction which involves a hydrogen atom that is located between a pair of other atoms such as nitrogen, oxygen, and fluorine which have a high affinity for electrons, and such a bond is weaker than an ionic bond or a covalent bond but are stronger than van der Waals forces and dispersion forces.
Hydrogen bonding is primarily responsible for the high boiling point of water solvent. Hydrogen bonding is a strong affinity. Hydrogen bonding is created when a hydrogen atom is bonded to an electronegative atom by approaching a nearby electronegative atom.
Therefore, the correct option is B.

how is the law of mendelian inheritance violated in down's syndrome
Answer:
According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.
In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

what was the speed of a car that traveled 240 m in 12 s
Answer:20
Explanation: Because when you divied 240 by 12 you get 20.
240/12=20
Answer:
20m/s
Explanation:
Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

Which statement describes the general relationship between the temperature and the absolute brightness of main sequence stars?
As temperature decreases, absolute brightness increases.
As temperature decreases, absolute brightness remains the same.
As temperature increases, absolute brightness increases.
As temperature increases, absolute brightness remains the same.
Answer:
As temperature increases, absolute brightness increases
Explanation:
As temperature increases, absolute brightness increases
As temperature increases, absolute brightness increases. Therefore, option (C) is correct.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.
Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness
