Explain why tongue rolling ability is a discontinuous variation
Since tongue rolling ability is determined by a single gene with two separate alleles—the dominant allele, which codes for tongue rolling ability, and the recessive allele, which codes for tongue rolling incapacity—tongue rolling ability is a discontinuous variation.
What is Tongue rolling ability?The hereditary characteristic known as tongue rolling ability controls whether or not a person can roll their tongue into a tube shape. This characteristic is frequently used as an illustration of a straightforward hereditary trait with discontinuous variation since there are only two possible outcomes: either a person rolls their tongue or they do not.
Either a person has the recessive allele, which prevents them from rolling their tongue, or they have the dominant allele, which allows them to roll their tongue. There is no intermediate or in-between trait, and the presence or absence of the dominant allele is a distinct, plainly observable phenotype.
Therefore, the capacity for tongue rolling is an illustration of a discontinuous variation.

Which of these best explains why mosquito populations show an exponential increase followed by a die off on a seasonal basis with a regular pattern?
Answer:
B) Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
Explanation:
Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
Answer:
B. Mosquitoes are limited by temperature, with reproduction levels high in the spring and summer and low in the fall and winter.
-Explanation:
Since mosquitoes reproduce when the temperatures are warm, their populations undergo a predictable increase in the warmer months. The first frost will kill many of the larvae and decrease the reproduction of these short-lived individuals.
Since sun can filter to the bottom of a pond because it is shallower than a lake, what would you find at the bottom of a pond that you won't find at the bottom of a lake? A. Rocks B. Fish C. Plants D.Mud
Answer:
The correct answer is - C. Plants.
Explanation:
As we know and also given that the pond is usually smaller and shallower than a lake. Due to this reason, ponds have plants growing on the bottom of them from one side to the other as they get enough light as there is only the photic zone in ponds.
In lakes, there are various zones present and the lakes are deep and big to the ponds and the bottom of the lakes did not get sunlight. Plants require sunlight to grow and lakes are usually too deep to get the sunlight for plants to grow on the bottom.

Explanation:
It is small disturbances in topography that set off reactions that alter the path of a river Any kind of weakening of the sediment on one side of a river due to animal activity it could also be because of soil erosion, or human activity can draw the motion of the water towards that side.
What ratio of plants in the offspring would you predict from a Yy x Yy cross?
Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.
Si tu masa corporal fuera 10 kg, ¿qué peso tendrías aquí en la tierra al
nivel del mar?
Answer: 98.1 N
Explanation:
En física, la masa es una magnitud y una propiedad que se mide en unidades, como kilogramos. Por otro lado, el peso es una magnitud vectorial o fuerza que se mide en netown (N). El cuerpo experimenta una atracción hacia la tierra, llamada gravedad, la cual es un fenómenos en donde dos objetos o cuerpos son atraídos entre sí. En este caso, la masa del cuerpo de 10 kg es muy inferior a la masa de la Tierra. Por lo que la atracción del cuerpo hacia la tierra es despreciable, y solo vamos a tomar en cuenta la atracción de la Tierra hacia el cuerpo.
La fuerza de gravedad a nivel del mar es de 9,81 metros/segundos^2. Reemplazando los datos en la ecuación de fuerza, la cual es:
Fuerza = masa x aceleración
obtenemos que:
Fuerza= 10 kg x 9,81 m/s^2 = 98.1 N
Por lo que el peso a nivel del mar es de 98.1 N.

Researchers used DNA sequencing techniques to find similarities of Hox genes in roundworms, arthropods, mollusks, echinoderms, cephalochordates, and vertebrates. What did they find out about these genes? Select all that apply. A. Hox genes provide information about evolutionary relationships. B. Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times. C. Hox genes are regulatory genes that determine body plans of animals. D. Only some animals that have been tested have Hox genes, suggesting that Hox genes have no function and only evolved recently.
Answer:
(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.
Explanation:
Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.

Answer:
The PH at which an enzyme will function best is;
In the optimal range
Explanation:
Every enzyme has an optimal pH value which is specific for the enzyme, and where their maximum activity of the enzyme is observed, which is known as its optimal pH
When the enzyme is placed in a different pH, the enzyme activity is observed to be diminishing until the effect of the enzyme stops
This is so because, as the pH of the environment changes, the shape of the active site on the substrate to which the enzyme binds to have an effect changes and the enzyme is no longer able to effectively interact with the substrate
The enzymes in the stomach work best in the acidic environment of the stomach and have an optimal pH of 2, while the enzymes of the small intestine have an optimal pH of 7.5

New alleles can arise in both asexual and sexual reproduction.
Which of the following statements is TRUE based on the disadvantages of sexual and asexual reproduction.
A- Gametogenesis is the only source of genetic variation for sexual reproduction
B- This answer choice is wrong
C- Mutations are the only source of genetic variation for asexual reproduction
D- Meiosis is the only source of genetic variation for sexual reproduction
Answer:
C - Mutations are the only source of genetic variation for asexual reproduction
Mutations are the only source of genetic variation for asexual reproduction.
What is mutation?
A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings. There are numerous explanations for why mutations typically don't have significant effects.
Therefore, Mutations are the only source of genetic variation for asexual reproduction.
