Why does sexual reproduction result in more genetic variation in a species
than asexual reproduction?
O
A. In sexual reproduction, offspring have more chromosomes than
either parent
O
B. In sexual reproduction, offspring have fewer genes.
O
C. In sexual reproduction, offspring are not identical to either parent.
Answer: C. In sexual reproduction, offspring are not identical to either parent
Explanation:
Sexual reproduction results in more genetic variation because offsprings are not identical to either parent.
What is sexual reproduction?Sexual reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent.Sexual reproduction involves the fusion of male and female gametes which leads to genetic variation.Crossing between male and female chromosomes takes place. Due to the crossing of chromosomes the child receives some features of the father and others of the mother.What is asexual reproduction?Asexual reproduction occurs when a single parent divides.It does not involve the fusion of gametes and the offspring will be identical to the parent.To learn more about Reproduction:

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.
Interneurons relay the impulse to motor neurons in the spinal cord.
She immediately moves her foot.
The sensory neuron generates an impulse.
Receptors in her toe receive stimuli.
Motor neurons signal the leg muscles.
Answer:
Correct order is
a) Receptors in her toe receive stimuli.
b) The sensory neuron generates an impulse.
c) Inter neurons relay the impulse to motor neurons in the spinal cord.
d) Motor neurons signal the leg muscles.
e) She immediately moves her foot.
Explanation:
Foot of Lucia contains stimuli receptors. As Lucia steps on the nail, the receptors in the toe receives the stimuli and hence her sensory neurons becomes active and they generate an impulse. These impulses are transmitted from sensory neurons via inter neurons to the brain. Brain processes the information and sends the message via inter neurons to the motor neurons. Motor neurons then signals the leg muscles and then she immediately removes her leg away from the pin.
Hence correct order is
a) Receptors in her toe receive stimuli.
b) The sensory neuron generates an impulse.
c) Inter neurons relay the impulse to motor neurons in the spinal cord.
d) Motor neurons signal the leg muscles.
e) She immediately moves her foot.
Final answer:
The events in the nervous system when Lucia steps on a nail form a reflex arc, starting with pain receptors and following through sensory neurons, interneurons in the spinal cord, motor neurons, and finally resulting in muscle contraction and movement.
Explanation:
The student's question pertains to the sequence of events that occur in the nervous system when Lucia steps on a nail. To answer this question, we will arrange the events in chronological order as they would happen within a reflex arc.
Receptors in her toe receive stimuli.
The sensory neuron generates an impulse.
Interneurons relay the impulse to motor neurons in the spinal cord.
Motor neurons signal the leg muscles.
She immediately moves her foot.
The sequence starts with the activation of pain receptors (nociceptors) when the nail is stepped on. This stimulus is then conveyed through sensory neurons to the spinal cord, where it is processed by interneurons.
The interneurons quickly transmit the impulse to motor neurons, which signal the leg muscles to contract, resulting in the immediate withdrawal of the foot. This entire process forms a reflex arc, allowing for a rapid response without the need for brain involvement.

What is the only genotype of two parents that would ensure that their offspring could not roll their tongue
Answer:
tt genotype of both parents
Explanation:
Since tongue rolling is genetically dominant trait, this means that even a single copy of the dominant gene (for tongue rolling) is enough for the kids to express the trait. The dominant allele for the gene is indicated by capital T and the recessive allele for non-rolling tongue is indicated by small t.
Since the trait of rolling tongue is dominant in nature, it means that even if one of the parents is heterozygous or homozygoud for T (TT), there will be chances that kids will be tongue rollers. So the only case when any of the kids will never be tongue rollers is one when both parents are homozygous for the allele (tt) that is for non-tongue rolling. Attached genetic picture will help you understand better.

Final answer:
Ganymede is considered a moon instead of a planet due to its orbital relationship to Jupiter, despite its size compared to Mercury and Mars.
Explanation:
The reason why Ganymede is called a moon and not a planet despite its size compared to Mercury and Mars is that it moves in an orbit around Jupiter.
Moons are natural satellites that orbit planets, while planets orbit the Sun. Therefore, Ganymede's orbit around Jupiter classifies it as a moon, even though it is larger than Mercury and Mars.
Ganymede's classification as a moon is based on its relationship to Jupiter and its orbital behavior in the solar system.

successful plant-breeding experiments was that pea plants usually ___,
Answer:
Besides the fact that pea plants have a short generation time, the key to Mendel's successful plant-breeding experiments was that pea plants usually self- pollinate.
The key to Mendel's successful plant-breeding experiments with pea plants was their true-breeding nature, guaranteeing consistent offspring. The short generation time of pea plants also enabled several generations to be evaluated quickly.
Explanation:The key to Mendel's successful plant-breeding experiments with pea plants was that they were true-breeding. True-breeding plants always produce offspring that look like the parent. This allowed Mendel to avoid unexpected traits in the offspring and ensure consistency in his experiments. Additionally, pea plants have a short generation time, which means that several generations can be evaluated in a relatively short period of time. These factors made pea plants an ideal choice for Mendel's genetics research.
The true-breeding nature of pea plants was crucial to Mendel’s experiments. True-breeding, or purebred, plants are those that, when self-pollinated, consistently produce offspring with the same traits as the parents. This characteristic allowed Mendel to conduct controlled crosses between different varieties of pea plants and observe the predictable inheritance patterns of specific traits in subsequent generations. By working with true-breeding lines, Mendel could ensure that the traits he was studying were not influenced by genetic variability within the parental plants.

Using the catalase test, a Streptococcus sample would be:
A. Gram (+), Catalase (+)
B. Gram (-) Catalase (+)
C. Gram (-), Catalase (-)
D. Gram (+), Catalase (-)
Answer:
The correct answer would be option D: Gram (+) and Catalase (-).
Explanation:
Streptococcus bacteria have a cellular wall made up of various layers of peptidoglycan which is a macromolecule composed of amino acids and sugars that are assembled as if woven together, therefore they are Gram (+) bacteria.
The Catalase test is used to determine if a bacteria has the ability to produce the Catalase enzyme, the principle of the test is, when the bacteria comes into contact with hydrogen peroxide, if it is Catalase (+) then oxygen bubbles will appear, since the bacteria is able to break down hydrogen peroxide into oxygen and water, and if the bacteria is Catalase (-) then, nothing will happen.
In this case, Streptococcus bacteria are not able to produce the Catalase enzyme, therefore, they are Catalase (-).
Answers A, B and C are incorrect because they have the wrong combinations of a results, in answer A: Streptococcus bacteria are Gram (+) but Catalase (-), in answer B: Streptococcus bacteria are neither Gram (-) or Catalase (+), and in answer C: Streptococcus bacteria are Catalase (-) but are not Gram (-).
Final answer:
A Streptococcus sample would yield a result of Gram (+), Catalase (-), which is answer D. This is based on the fact that Streptococcus species are catalase-negative, so no bubbling would occur during the catalase test.
Explanation:
Using the catalase test, a Streptococcus sample would be Gram (+), and Catalase (-). This means the correct answer is D. Gram (+), Catalase (-). The catalase test differentiates between bacterial species that produce the enzyme catalase, such as Staphylococcus species, and those that do not, such as Streptococcus species. Streptococcus species are catalase-negative, meaning no bubbles will form when hydrogen peroxide is added to a culture sample. In contrast, Staphylococcus species are catalase-positive and will produce bubbles upon the addition of hydrogen peroxide due to the degradation of hydrogen peroxide into water and oxygen gas.
