Answer:
Ammonites existed only in the oceans.
Explanation:
Index fossils serve as a relative dating marker for geologic time periods and the rocks formed at those times. The fossils are of species that lived for only a short while, though that could be millions of years, and were widespread on the Earth. Ammonites are good index fossils for several reasons. First, they are easily identified by their spiral shells.
The statement explains why ammonites are a good example of an index fossil

Explanation:
under the biological species concept, what criterion is used to assign populations of organisms to the same biological species?
Answer: According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring. Speciation is the process by which new species form
Indigestible residues along with some of the non-reabsorbed secretions of digestive organs, undergo ____________ where the fluids are removed and a remaining solid is created.
The digestive system is involved in the breakdown of molecules to yield energy. As food passes along the digestive gut, it undergoes various processes in its breakdown.
Indigestible residues along with some of the non-reabsorbed secretions of digestive organs, undergo Compaction where the fluids are removed and a remaining solid is created.
Compaction during digestion occurs in the large intestines. This occurs wherein water is removed from the indigestible residues and reabsorbed enabling the compacting of these waste materials.

Based on this diagram label the positive and negative sides of the DNA fingerprint with a + and – sign.
We can say that the top of the gel, where the DNA samples were applied, is the negative side, while the bottom of the gel is the positive side.
We can arrive at this answer because:
DNA is a negatively charged molecule.For this reason, when DNA is applied in an electrophoresis vat, it must be placed in the negatively charged portion.This is because the electrophoresis vat will allow an electrical discharge to pass through the vat and drag the DNA from the negative side to the positive side.This movement allows the DNA to present a series of fragments of different sizes that will be observed in a fingerprint, such as the one presented in the question above.
In the figure below you can more accurately see the positive and negative sides.

If the area had experienced a wet season two years after the drought instead of a dry season,
what kind of evolution would you expect? Explain your answer.
The organisms will start adaptation to that environment in order to survive.
If the area had experienced a wet season for two years after the drought instead of a dry season then we expect that the organisms that lives in that environment will start adaptation to that humid environment in order to survive.
What is adaptation?Adaptation occurs when an organism adapts certain actions to a certain environment in order to live more comfortable. If the organism do not adopt certain features then it will be extinct from that environment while on the other hand, those organism which adopt certain features will be able to survive so we can conclude that the organisms will start adaptation to that environment in order to survive.

Which of the following is an advantage of sexual reproduction?
A. Produce identical copies of an organism.
B. Produce natural variation to adapt to environmental change.
C. Quickly populate a new habitat.
D. Reproduce very quickly.
Answer:
B
Explanation:
Produce natural variation to adapt to environmental change is an advantage of sexual reproduction. Correct Option is 2.
The advantage of sexual reproduction is that it produces genetic variation within a population. During sexual reproduction, offspring inherit a combination of genes from both parents, leading to unique genetic combinations. This genetic diversity results in natural variation among individuals within a population.
This variation is advantageous because it allows a population to better adapt to changing environmental conditions. In a changing environment, some individuals may possess traits that are better suited to the new conditions, making them more likely to survive and reproduce. Through natural selection, these advantageous traits can become more prevalent in the population over time, enhancing the population's overall ability to adapt and thrive.

Place each land feature in the correct category based on the process that causes its formation
•Oxbow lake. Eroison by rivers
•Alluvial fan
•Delta
•Meander. Deposition by rivers
•Waterfall
•Flood plain
Deposition by rivers generates alluvial fans and deltas. Moreover, erosion by rivers generates waterfalls, flood plains, oxbow lakes and meanders.
An oxbow lake is a lake located in a meandering channel, and therefore on a floodplain.
Alluvial fans are accumulations of sediments created as flowing water bodies interact with mountains or hills.
A delta is a formation of land composed of sediments located in the mouth of the river.
A waterfall is a point in a river where water spills suddenly downward.

Answer: If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will D. complete the cycle and divide. G1 checkpoint occurs between the G1 and S phase of the cell cycle. When the cell is grown sufficiently and produces all components of DNA replication it enters in the S phase.
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide.
What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.
