If a moon were discovered to be at 1.5AU from the sun, it would be how far from the sun in kilometers? A. 22,500km
B.225,000km
C.22,500,000km
D.225,000,000km
Answers
AU means astronomical unit. It is used by the astronomers to measure large distances in the Solar System. 1 AU is the average distance from Sun to Earth which is 149, 598, 000 km.
So to get the km value of 1.5 AU.
1.5 x 149, 598, 000 = 224, 397, 000
Round off to 225, 000, 000
Answer: D. 225,000,000km
Explanation:
An Astronomical Unit is the average distance between the Earth and the Sun. It is a unit of length which is used to measure distances in our galaxy.
1 astronomical unit is approximately equal to 150 million kilometers. 1 million is .
Thus 1 Astronomical unit (AU) is equal to 150 million km or
So 1.5 Astronomical unit (AU)=
Thus correct option is D.

Answer: there are six possible genotypes
Explanation:
With three alleles 1, 2, 3
genotypes: 11, 12, 13, 22, 23, 33. First we must appreciate that genes do not act in isolation. The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype.

Answer:
The term that is used to describe all the species, which lives in the Arctic National Wildlife Refuge is community.
Explanation:
The community also considered as the biological community signifies towards an associating group of distinct species in a specific location. For example, the plants grown underneath and a forest of trees, inhabited by animals, and the roots in soil constituting bacteria and fungi, leads to the formation of a biological community.

E)feet modified as tentacles
Answers
Answer:
The correct answer is option B, C, AND E.
Explanation:
Cephalopods are the member of class Cephalopoda of the molluscan group such as squid. They're made up of a body, a head and a foot having a muscular case called a mantle that protects their organs.
Some species also have tentacles that are modified of their feet.
Cephalopods nervous system is the most complex of any invertebrate nervous system.
Member of this class shows different types of swimming to fishes which is jet propulsion such as squid.
Thus, the correct answer is option B, C, AND E.
the answer is B complex nervous system

Answer:
c. limiting factor.
Explanation:
The limiting factors are environmental or ecological factors that act directly on the living beings of a population, limiting their size, since these factors determine their birth, mortality, migrations, etc. They are the ones that regulate the growth and expansion of a species.
If environmental factors are optimal for the development of a living being, they favor the growth of that organism in that biotope. But if any of these factors prevents the growth of a species, there is talk of a limiting factor.
Among these physical and chemical factors that determine the biotope include:
- Abiotic factors (do not depend on population density):
Climate:
Light. Only the most superficial organisms access it in water. On land, there is also competition in leafy areas to access it.
Temperature. Some living beings cannot live at the temperature that others live.
Water: It is necessary that it rains or that living beings can access water in order to live. If there is no water, they die.
Atmospheric pressure.
Non-climatic:
Soil factors: The chemical composition of the soil, its pH, salinity, etc. It makes some plant species may or may not survive in it.
Factors of the aquatic environment: The concentration of O2, dissolved CO2, the degree of salinity, the existence of currents, etc., limits the development of some organisms.
- Biotic factors (depend on population density):
Food. If they do not have enough food, the population will have to be smaller.
Interspecific relationships. The number of predators limits the number of prey, and vice versa.
Intraspecific relationships. The relationships established between individuals of the same species can also limit their existence.
