what advantage do multicellular organisms have over unicellular organisms?

Answer:

gravity

Explanation:

gravity is the force that pulls substances towards the earth

Gravitational force is responsible for pulling these gaseous molecules closer to Earth’s surface.

An Atmosphere may be defined as a collection of layers that consist of several gases that surround the planet or any celestial body.

Gravitational force involves the attraction of numerous compounds as well as gaseous molecules towards the earth's surface.

Therefore, more than 50% of the gas molecules in Earth’s atmosphere are found in the troposphere layer.

C, The first position

The answer is attached below:

Answer:

In genetics, a trait is considered dominant when it is expressed in the phenotype of a heterozygous individual, meaning that it only requires one copy of the dominant allele to be expressed. On the other hand, a recessive trait is only expressed when both copies of the allele are present in the individual's genotype.

To provide the best evidence that a trait is dominant, we would need to observe the trait in the phenotype of all individuals who carry at least one copy of the dominant allele. This means that if an individual has one dominant allele and one recessive allele, they should still show the dominant trait in their phenotype.

In practice, this could be demonstrated through a series of crosses between individuals with known genotypes. If the offspring of a cross between a homozygous dominant individual and a heterozygous individual all show the dominant trait, this would be strong evidence that the trait is dominant. Similarly, if the offspring of a cross between two heterozygous individuals show the dominant trait in a 3:1 ratio, this would also support the idea that the trait is dominant.

In general, the best evidence for a dominant trait would be consistent expression of the trait in the phenotype of individuals who carry at least one copy of the dominant allele. This can be observed through controlled breeding experiments and statistical analysis of the resulting offspring.

Reflex response helps to keep organisms alive by quickening their reaction times when in danger instead of having to think about what they need to do

Explanation:

Think about your friend throwing something at your face. What do you do- you probably cover up your face, or try to move out of the way. This is a reflex, and it saves your face from pain. While this is a silly example, these type of automatic "reflex" reactions are absolutely vital in the wild. Mice have the reflex to run when a they see or hear what they think is a predator. This give them the precious seconds they need to escape certain death. Say they didn't move on reflex. If they instead sat and thought about what they needed to do, the predator would catch them and they would die.

The prompt is culled from "HonerScience" Gizmo. The objective is the compare the Planetary motion of Pluto's Orbital Radius, against the period of it's Orbit as depicted in the Gizmo. It is to be noted that Pluto's Orbital Radius is 39.529 AU while it's period of Orbit is 249 years.

For roughly circular orbits, the orbital radius is the distance between an item in space and the body it is circling. When an object circles a body in space, it spins around it, forming a circle or an ellipse depending on the orbit.

If the mass of the orbiting star is known, Kepler's Third Law may be used to calculate the planet's orbital radius (R3=T2Mstar/Msun, the radius is in AU, and the period is in earth years).

The earth's radius and the radius of its orbit around the sun are 6371 km and 149x109 km, respectively.

Explanation:

because erosion is the washing away of soil

Erosion and deposition are the formed on this delta. Thus, the correct option is A.

Erosion is the action of the surface processes such as water flow or wind which removes the soil, rock, or dissolved materials from one location on the Earth's crust and then transports it to another location on the Earth's crust where it is deposited. The erosion is distinct from that of weathering that involves no movement.

Deposition is the laying down of the sediment carried out through the wind, flowing water, the sea or ice. Sediment on the Earth's crust can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by the organic activity such as sea shells or by evaporation.

Therefore, the correct option is A.

The length of a wave—which could be an electromagnetic wave, a sound wave, or any other wave—is the distance between its crests and troughs. The wave's crest is its highest point, while its dip is its lowest and wavelength.

Thus, Because a wavelength represents a distance or length, it is expressed in length units like meters, centimeters, milimeters, nanometers, etc.

Light's wavelength changes with color, or it differs for each hue. While violet has the shortest wavelength, red has the longest. UV light has a shorter wavelength than violet light. In a similar vein, infrared energy has a larger wavelength than red light.

Frequency and wavelength are inversely proportional. This implies that frequency decreases as wavelength increases. Similar to this, a shorter wavelength results in a higher frequency.

Thus, The length of a wave—which could be an electromagnetic wave, a sound wave, or any other wave—is the distance between its crests and troughs. The wave's crest is its highest point, while its dip is its lowest and wavelength.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Answer:

Explanation:

urbanization converts water holding capacity of the soil decreases and runoff water rates increase which turns into soil erosion

Answer:Temperature and pressure progressively increase with increased proximity to Earth’s core. Recent studies indicate the core’s temperature may be close to 11,000 degrees Fahrenheit; that’s nearly 2,000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.

Explanation:

Since genes D and E are said to assort independently, we can assume that they are on different chromosomes and therefore not linked.

To solve this problem, we need to first determine the genotypes of the F1 females. Since all of the F1 females were wild-type, we know that they must have had at least one dominant allele for each of the three traits: wild-type eye (cn+), normal wings (vg+), and normal body (rf+).

We can represent the genotype of the F1 females as follows: cn+ vg+ rf+/cn+ vg+ rf+. When these females were test-crossed with homozygous recessive males (cn cn vg vg rf rf), we observed the following offspring:

Cinnabar vestigial (cn vg): 382

Roof (rf): 401

Cinnabar (cn): 3

Roof vestigial (rf vg): 4

Cinnabar vestigial roof (cn vg rf): 59

Wild-type (cn+ vg+ rf+): 67

Cinnabar roof (cn rf): 44

Vestigial (vg): 40

We can use these numbers to calculate the recombination frequency (RF) between each pair of loci using the formula: RF = (number of recombinant offspring / total number of offspring) x 100%.

RF between cn and vg:

Recombinant offspring = cn vg + cn + cn vg rf + cn rf = 382 + 3 + 4 + 44 = 433

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (433/1000) x 100% = 43.3%

RF between vg and rf:

Recombinant offspring = cn vg rf + cn+ vg+ rf+ = 59 + 67 = 126

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (126/1000) x 100% = 12.6%

RF between cn and rf:

Recombinant offspring = cn rf + cn+ vg+ rf+ = 44 + 67 = 111

Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000

RF = (111/1000) x 100% = 11.1%

Now we can use these recombination frequencies to construct a genetic map:

cn -- 43.3 mu -- vg -- 12.6 mu -- rf
