C) Underwater organisms in dry land
Explanation:
The listed options are:
A) Large number different-sized footprints.
B) Plant but no animal fossils.
C) Underwater organisms in dry land.
D) Straight teeth buried below curved teeth.
Discovering fossils of underwater organisms in dry land <u>demonstrates that thousands to millions of years ago, there was a body of water such as an ocean, lake, or river in an area that is now dry land.</u> This gives important insights into what was the Earth's climate at that epoch and how it has changed throughout time.
This discovery could allow researchers to study what the conditions were at that time and why that body of water dried out. Moreover, it could lead to answers of the reasons behind the extinctions or evolution of some underwater organisms.
Homologous types of chromosomes pair together to form a bivalent. They undergo synapsis which is the process of pairing. In each bivalent. there would be a total of two centromeres and four sister chromatids. crossing over is the term used for the physical exchange of material between two homologous chromosomes. A<span> chiasma</span><span> is the visible evidence that exchange of genetic material occured.</span>
One the XY belong to the male (XX is for females ) and these chromosomes are sex chromosomes and are always the same in every human being ( well except for some genetic disorders)
Answer:
The Teeth
Explanation:
Carnivores have teeth that are more for ripping and shredding a prey's flesh. They are sharper. Herbivores have more square and flat teeth for mashing leaves and grass.
The second on :” the number of valence electrons stays the same” because a valence electron is the number of electrons on the outer shell of the atom and if it’s in group one then the outer shell of any element will have one electron on its outer shell
