Determine the statement that is logically equivalent to this conditional statement. If there is a thunderstorm, the lake floods.
Answer:
This question lacks options, the options are:
A) If the lake does not flood, there is a thunderstorm.
B) If the lake floods, then there is not a thunderstorm.
C) If there is not a thunderstorm, the lake does not flood.
D) If the lake does not flood, then there is not a thunderstorm.
The correct answer is D
Explanation:
A conditional statement is a statement whose effect is dependent on another, it is usually recognized with the IF word. A Contrapositive of an original conditional statement, is the inverse of the converse of an original statement that doesn't change the meaning of the original statement.
For example; A -> B is the original conditional statement
Converse is B -> A
The Contrapositive is (not B -> not A)
The original conditional statement is: If there is a thunderstorm, the lake floods.
(This means that there is flooding of the lake in the presence of a thunderstorm)
The contrapositive of this statement is:
If the lake does not flood, then there is not a thunderstorm.
(This retains the meaning of the original statement. It means that the absence of a flood certainly means the absence of a thunderstorm)
Since the contrapositive is logically equivalent to the conditional statement, then the option D is the logically equivalent to the conditional statement.
Note: Option C is wrong because other factors might cause flooding of the lake, so the absence of thunderstorm doesn't mean there'll be no flooding of the lake but no flooding certainly means no thunderstorm, which option D is portraying.

Explain what causes genetic mutations please, thank you again!
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
Which statement describes asexual reproduction, but not sexual reproduction?
Answer:
__________________________
An Asexual reproduction means that the parent organism will simply split into two child organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA. Therefore the child and the parent organism will contain exactly the same genetic material

Demonstrate through chemical modeling what happens to the protein structure (keratin) of curly hair after a chemical relaxer and heat are applied and what happens to straight hair after a chemical perm or relaxer is applied.
Answer:
Denaturation occurs.
Explanation:
When a chemical relaxer and heat applied to a curly hair, the protein present inside your hair get denature. Due to this denaturation of protein in the hair, the hair are soft and flexible which can be converted into any direction and different styles can be done. If chemical perm or relaxer is applied to straight hairs, it also denature the protein and make the hair curly.

Which of the following is a benefit of the water cycle to life?
a. maintaining homeostasis
b. transporting nutrients
C. cycling nutrients
d. all of the above
Answer:
D. All of the above
Explanation:
I just took the test
The benefits of the water cycle to life include maintaining homeostasis, transporting nutrients, and cycling nutrients.
What do you mean by the Water cycle?The water cycle may be defined as the continuous movement of water on, above, and below the earth's surface.
The water cycle helps in maintaining the process of homeostasis by actual photosynthesis and respiration mechanisms in the organisms. It also cycles nutrients from the surface of the earth to the whole atmosphere in a gradual way.
Therefore, the benefits of the water cycle to life include maintaining homeostasis, transporting nutrients, and cycling nutrients.

What kind of cell is produced by fertilization? Haploid cells or diploid cells
Diploid cell is Produced by fertilization.
What is Fertilization?Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development.
Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation.
During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.
Therefore, Diploid cell is Produced by fertilization.

The correct route of administration for long-acting forms of penicillin is: a. Intramuscular b. Intravenous c. Oral d. Sublingual
Answer:
Intramuscular
Explanation:
Intramuscular is a method of administering injection directly into the muscles for effective functioning.
Long acting penicillin are administered intramuscularly because of penicillin sensitive microorganisms that are subsceptible to low serum levels which is associated with penicillin dosage in the body and penicillin Has low level of solubility therefore it is slowly released into the muscles sites.
- ¿Qué ruta sigue cada uno DE LOS TRIGLICERIDOS en su afán de obtener energía?… ¡sí, energía llamada ATP! - Ruta metabólica que siguieron el glicerol y el ácido graso.
Answer:
Los trigliceridos antes de ser disociados en moleculas energeticas necesitan ser absorvidos.
Para eso es importante aclarar que se absorbe nen elintestino en forma de quilomicron, por su caracteristica hidrofuga y son emulsionados por el jugo pancreatico y los jugos provenientes de la vesicula.
Una vez absorbido, este puede seguir diferentes rutas metabolicas de un cuerdo a la necesidad energetica de la persona.
En el caso que una persona obtiene energía de un acido graso o de su reserva adiposa es por que no hay mas reserva de glucogeno, es decir en ayunos prolongados, en personas con dificultad de asimulacion glucosidica como los diabeticos, personas con trastornos anorexicos recientes.
Explanation:
Las grasas contienen una gran aporte de ATP posterior a la adicion de CO2 y H20, en los procesos de beta oxidacion y el ciclo del acido citrico.
El metabolismo de estos se considera toxico en momentos prolongados ya que el producto de su metabolizacion son los cuerpos cetonicos. Los cuerpos cetonicos aumentan la cetoacidosis de la sangre y atraviezan la barrera hematoencefalica.
El ph por la cetoacidosis disminuye generando toxicidad tisular y del snc, hiperventilacion, hipercapnia, cansancio, aliento cetonico, fallo proteico de algunos complejos enzimaticos de nuestro organismo.
Ademas esimportante aclarar que el ser humano obtiene carbohidratos del glicerol y no de la porcion de acidos grasos.

An organism is heterozygous for a gene that follows Mendels law of dominance which allele will be expressed as its phenotype
Answer:
The dominant allele
Explanation:
The dominant allele will be expressed because in a heterozygous genotype, the phenotype will always show the dominant gene (in Mendelian genetics)

How does salt maintain fluid levels inside your body?
Answer:
These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine. The advantage of this mechanism is that the long-term maintenance of body fluids isn't as dependent on external water sources as once believed.
