Answer:
Manatees are considered tetrapods due to tetrapod ancestor.
Explanation:
Manatees are considered tetrapods even though they lack hind limbs because they are the descended of the tetrapod common ancestor. The oldest ancestors of manatees were pig-like, four-legged animal that lives on land and eats grass but when some of them start living in the water so with the passage of time their hind limbs disappear because there is no need of these legs in water. So due to link with the four-legged animal manatees are considered tetrapods.
Manatees are considered tetrapods despite lacking four limbs because there ancestors were belonging to the family of tetrapods.
Manatees
Manatees are aquatic animals, who live in water. They are considered tetrapods despite lacking hind limbs because their common ancestor were belonging to the family of tetrapod.
They likely share jaws and skin with leopards and other mammals. The oldest ancestors of manatees were four-legged animal that lives on land and eats grass, which were way different than the present manatees, because manatees at present lost their hind limbs, and live in water.

Answer:
Most of the water on earth is located in the oceans
Explanation:
The question states, 97 percent of the worlds water is salt water, which is what oceans are made up of, and, obviously, oceans are made up of salt water, and oceans also cover up approximately 71 percent of the earth, which from there, we can infer, that most of Earths' water is in the oceans.

on an “X”-shaped floating object. To
balance themselves, they want to
make themselves the vertices of a
parallelogram.
Madison
Shelby
Nikia
Angela
In order to achieve this, do all four of
them have to be the same distance from
the center of the object? Explain.
Answer:
depends
Explanation:
in order to balance at the same distance from the center, the people opposite each other would have to weigh the same amount,
if they weigh different amounts, then the heavier person would have to be closer to the center in order to balance.

Name 2 ways wind energy is used to move objects.
Name 2 ways water energy is used to move objects.
Answer:
Wind - Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. ... The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.
Water - The energy from moving water can be used to create electricity in several different ways. For example: A hydroelectric dam captures energy from the movement of a river. Dam operators control the flow of water and the amount of electricity produced

On the planet Greenport, individuals display two distinct phenotypes: their favorite color s blue versus their favorite color is green. Every Greenportian has one of these two phenotypes. Suppose the phenotypes are determined by genotypes on two loci. The first locus, Quogue, has alleles F and f. The second locus, Massapequa, has alleles G and g. These loci act in an epistatic manner to produce the favorite-color phenotypes. A cross between two doubly heterozygous individuals, that is, each with the two-locus genotype FfGg, produces 1100 offspring whose favorite color is blue, and 875 offspring whose favorite color is green. What form of epistasis is most consistent with these counts
Answer:
double recessive epistasis.

A 15 mL sample of gasoline has a mass of 11 g. What is the density of the gasoline?
The density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.
DENSITY:The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;Density = mass ÷ volume
According to this question, a 15 mL sample of gasoline has a mass of 11 g. The density of gasoline is calculated as follows:Density = 11g ÷ 15mL
Density = 0.733g/mL
Therefore, the density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.

Answer:
1. Archipelago in Ecuador
2. Different beaks
3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. mutation, gene flow, genetic drift, and natural selection.
Mutation creates new genetic variation in a gene pool.
Gene flow and genetic drift alter allele frequencies in a gene pool.
5. The finches have few predators / competition for food.
Explanation:
1. Galapagos Islands located in archipelago in Ecuador near the west side of pacific ocean.
2. Different beaks variations did Charles Darwin observe after studying the Galapagos finches.
What are Galapagos Islands known for?The Galápagos are best known for their diverse of plant and animal species. Many species are endemic, that means they are not found anywhere else in the world.
3. Darwin used theory as he gave that survival of the fittest and other will die and evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. Darwin’s on the origin of Species, four factors affect evolution are
mutation: a mutation is a change in the DNA sequence of an organism. gene flow: is the introduction of genetic material from one population of a species to another, that leads to change in the composition of the gene pool of the receiving population.genetic drift: is a mechanism of evolution featured by random fluctuations in the frequency of a specific version of a gene (allele) in a population.natural selection: is the process by which populations of living organisms adapt and change.5. Daphne Major was the ideal place to study the evolution of the finches because the finches have few predators / competition for food on that island.
6. The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches which Grants studied, we can observe the working of the natural selection.

Often the growth cycle of one population has an effect on the cycle of another. As moose populations increase, for example, wolf populations also increase, which will then reduce the moose population. Thus, if we are considering the logistic equation for the wolf population, which of the factors accounts for the effect of wolves on the moose population
Answer:
K (carrying capacity)
Explanation:
In logistic growth, the population growth decreases as population size approaches its maximum value, i.e., when the carrying capacity of the environment is reached. In consequence, the carrying capacity can be defined as the maximum population size in a particular environment, which depends on a given resource (e.g., food, habitat, water, etc).
The logistic equation for logistic growth is: dN/dt = rN [K - N/K] >>
dN/dt = change in population size in a given time interval
N = population size
r = intrinsic rate of increase
K = carrying capacity

3. Describe a scenario where
identifying an individual through
the use of DNA fingerprinting
would be important.
DNA fingerprinting would be helpful in a crime scene with blood because it was indicate whether the person was a victim or a victim's relative.
What is DNA fingerprinting?Paternity testing and other forensic applications as well as criminal investigations all make use of DNA fingerprinting.
In these cases, the goal is to "match" two DNA fingerprints, such as a DNA sample from a known person and one from an unknown person, with one another.
A chemical test called DNA fingerprinting can reveal a person's or another living thing's genetic makeup. It is used as testimony in court, to identify corpses, find blood relatives, and search for medical treatments.
Therefore, at a crime scene, it will be helpful to do DNA fingerprinting with any sample including blood, and hair.
