A and B

Explanation:

the other 2 answers are just obviously wrong

They are both models of the solar system and they both show the position of the Earth relative to the sun. So the correct option is A and B.

A cosmological concept known as heliocentrism assumes that the Sun is located at or close to the center of the solar system or the universe, with the Earth and other planets revolving around it. The Greek philosophers Philolaus and Hicetas hypothesized independently that the Earth was a rotating sphere that rotated daily around a mysterious "central fire" that controlled the cosmos in the fifth century BC.

Two hundred years later, Aristarchus of Samos expanded on this concept by stating that the Sun, together with the Earth and other planets, revolved around a certain central object.

Any solar system (or universe) structure hypothesis that places Earth at the center of the cosmos is referred to as a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced (2nd century CE). It was widely believed until the 16th century when heliocentric theories like Nicolaus Copernicus took their place.

Therefore the correct options are A and B.

Answer: Skeletal system Explanation:

Answer:

14 Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

15 The halogen group of elements is the most reactive of the nonmetals. It is also the most reactive group of all chemical elements. Fluorine is the most reactive element in this group. Halogens are highly reactive because they are all electronegative.

16 Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

17 Group 1: Alkali Metals

Group 1 elements are called alkali metals because of their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water.

Answer:

High diversity of organisms are present.

Explanation:

Due to the existence of varied habitats in the ecosystem, there is high diversity of organisms in that ecosystem because there are different types of habitats are present in that ecosystem. Due to presence of more habitats for organisms and suitable conditions, different types of organisms lives in that one ecosystem which increases the diversity of that ecosystem. If the ecosystem has only one type of habitat, then the ecosystem will be less diversified as compared to ecosystem having varied habitats.

Answer:

1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

2. Anabolism  & Catabolism

3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.

4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

Answer:  flagellum, a plasma membrane and organelles.

Explanation: In that sense, it can be difficult to find traits that they all share. Still, Project Oceanography at the University of San Francisco indicates that single-celled organisms have a number of common characteristics, including the presence of flagellum, a plasma membrane and organelles.

Flagellum, a plasma membrane and organelles classify different kinds of single celled organism and prokaryotic organism.

Prokaryotic cell are single celled organism, do not have membrane bound organelles and its size varies from 0.2 μm – 2.0 μm.

Here the Cell wall is present but True Nucleus is absent, the cell wall is mainly involve in photosynthesis and provide protection to cell, the ribosomes are Smaller in size having 70s type and spherical in shape.

Circular DNA is present as genetic material in prokaryotes, Mitochondria is absent in prokaryotes, the reproduction usually occur by binary fission and some times it occurs through conjugation.
