B.
violet flowers = 0.62, white flowers = 0.38
C.
violet flowers = 0.3, white flowers = 0.7
D.
violet flowers = 0.49, white flowers = 0.61

Answers

The allelic frequency of each type of flower is violet flowers = 0.3, white flowers = 0.7, option C.

What is allelic frequency?

The incidence of a gene variant in a population is represented by the allele frequency. The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency and can be expressed as a decimal, a percentage, or a fraction.

To find the allele frequency:

Frequency = 98/200 = p = 0.49 for white (v) flowers

VV - dominant homozygote with violet flowers and with frequency p²

Vv - heterozygote with violet flowers and with frequency 2pq

vv - recessive homozygote with white flowers and with frequency q²

= 0.49 = √q²  = √0.49 = 0.7

Therefore q in the formula p + q = 1, = p + 0.7 = 1

p = 1 - 0.7 = 0.3

The frequency for violet flowers, p is 0.3 and white flowers, q is 0.7 with substitution method of the "p + q = 1, p2 + 2pq + q2 = 1" formula.

If the Earth did not spin what would happen?
Select one:
a. The Earth's wind would bend due to gravity.
Ob. The Earth would only have two large convection currents.
Oc. The Earth would have the same temperature throughout.
Od. The Earth would have several difference convection currents at different latitudes.

Answers

Answer:

B. The Earth would only have two large convection currents. The power of Earth's spin to turn flowing air is known as the Coriolis Effect. If the Earth didn't spin, there would be just one large convection cell between the equator and the North Pole and one large convection cell between the equator and the South Pole.

Explanation:

At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

If the planet stopped suddenly, everything on the surface would be destroyed, as the atmosphere, oceans and anything not nailed down kept spinning. Even braking to a halt over a minute would mean everything experienced a sideways deceleration of three-quarters of Earth’s gravity, so ‘down’ would feel like it was at an angle of 38° from the vertical. That’s enough to knock over most buildings.

If it slowed down over several years, it would still be a disaster. Without centrifugal force, the oceans would move towards the poles, dropping ocean depth by 8 km around the equator. Since this is less than the depth of the ocean there, Earth’s water would be divided into two huge polar oceans separated by a belt of land in the middle. Everything north of Spain would be underwater, as well as all of Antarctica.

Once Earth doesn’t spin on its own axis, a day lasts as long as a year. Everywhere receives six months of daylight, gradually heating up the planet to well over 100 °C. The huge central continent would get the hottest, and any remaining lakes and rivers would boil away and be blown to the poles by fierce winds. Even primitive life would only be possible along a narrow strip at the coast.

Many years ago, scientists
considered sponges to belong to Kingdom Plantae. What sort of evidence convinced them that sponges belonged to Kingdom Animalia?

Answers

Sponges were originally classified as plants because they were immobile and seemed to lack the basic animal characteristics of muscles and nerves. However, in the 1820s, scientists began to question this classification and discovered that sponges possess certain characteristics that are more characteristic of animals. For example, sponges have cells called choanocytes, which have flagella and are responsible for creating water currents within the sponge. These cells are similar to the collar cells found in the simplest animals, known as choanoflagellates. In addition, sponges have cells called amoebocytes that can move and digest food, which are characteristics of animal cells. These and other discoveries led scientists to reclassify sponges as animals and place them in the kingdom Animalia.

Answers

Ionic bonds are preferred as they are stronger than covalent bonds.

Why Ionic bonds are stronger than covalent bonds?

Ionic bonds result in a stable composite when all of the electrons between the components are transferred. While two elements only share electrons to form a stable molecule in a covalent bond.

Electrostatic force and Van Der Waals force are the forces that keep ions together and covalently linked elements together, respectively.

Cations and anions are created as a result of the complete transfer of electrons in ionic connections. As a result, these ions are attracted to one another strongly by electrostatic forces.

The Van Der Waal's force that exists between two covalently bonded elements is weaker than the electrostatic force because covalently bonded components only share electrons.

the blank determines which traits are adaptive during the process of natural selection

Answers

The environment determines which traits are adaptive during the process of natural selection.

What is natural selection?

Natural selection is the process by which certain traits become more or less common in a population over time based on their effect on the survival and reproduction of the individuals that possess them. The individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring. Over time, this can lead to the evolution of species, as certain traits become more common in the population.

Natural selection is one of the main mechanisms of evolution and is often referred to as "survival of the fittest," although the term "fitness" in this context refers to how well an organism can survive and reproduce in its specific environment, rather than its physical strength or athleticism. Charles Darwin and Alfred Russel Wallace were the first to propose the theory of natural selection, it's based on observations of natural variation within populations, heritability of traits and the fact that more individuals are born than can survive to reproduce.

What is Tiktaalik?

Tiktaalik is an extinct genus of fish that lived about 385 million years ago during the Late Devonian period. It is considered a transitional fossil, as it has characteristics of both fish and early tetrapods, four-legged land-dwelling animals. Tiktaalik could have existed in a Canadian environment, as it is known to have been found in the Canadian Arctic, specifically in the Elpistostege watsoni fossil beds of the Nunavut territory.

The environment during Late Devonian period in this region was a shallow freshwater delta or coastal plain that was home to a diverse array of fish and other aquatic organisms.

The three laws of inheritance proposed by Mendel are: the law of segregation, the law of dominance, and the law of independent assortment.

What are Mendel's law of inheritance?

The three laws of inheritance proposed by Gregor Mendel are:

The law of dominance: This law states that when an organism inherits two different forms of a gene (alleles) for a trait, one allele will be dominant and will be expressed in the organism's phenotype, while the other allele will be recessive and will not be expressed. For example, if an organism inherits one allele for brown eyes (B) and one allele for blue eyes (b), the brown eye allele is dominant and the organism will have brown eyes.

The law of segregation: This law states that during the formation of sex cells (gametes), the alleles for a trait separate from each other so that each gamete receives only one allele. This means that the offspring will inherit one allele from each parent and will therefore have a combination of alleles for a trait.

The law of independent assortment: This law states that the inheritance of one gene or trait is independent of the inheritance of another gene or trait. In other words, the alleles for different traits are inherited independently of each other and are not linked in any way. This means that the probability of inheriting a specific combination of alleles for different traits is the product of the probabilities of inheriting each allele for each trait.
