Answer:
No ocean is present 5 million years ago.
Explanation:
There is no ocean or sea in this area 5 million years ago because the land is present where these fossils live but with the passage of time the geography of that place changes and the ocean covered the area and these fossils remain below the ocean inside the layer of land. So we can conclude from the presence of these fossils that there is no ocean present in these regions 5 million years ago .
The area that contains many fossil clams used to covered with ocean water 5 million year ago
Clams are the the variety of shel-fish that are usually found in shallow water and are important to maintain the web of the ecosystem
5 million years ago the area of 50 km was covered with shallow water range but with the time and environmental change area with clams got vanished and with time changed into fossil.
Therefore, the area of 50 km used to covered with ocean water 5 million year ago.

Answer: There are 3 answers.
1- Plate tectonics causes loss or displacement of fossils.
2- Most organisms never fossilize, leaving holes in the fossil record
3- Because marine fossils are prevalent, this can lead people to believe they were more dominant than they actually were.

How can major geologic events and changes in organisms provide evidence for constructing a timeline of earth’s history?
Geological events play an important role in order to observe changes in organisms that significantly provide evidence for constructing a timeline of earth’s history.
What is the mechanism called which involves change?The mechanism that remarkably involves changes in living organisms is known as natural selection. These selections are based on the adaptations and requirements of the organisms with respect to nature.
Geological events and other scientific experiments utilize these geologic time scales in order to illustrate when events occurred within the history of Earth.
These geological time scales are utilized to express both consequences such as geological events and the events that occurred that widely impacted the life and strategies of plants and animals.
Therefore, geological events play an important role in order to observe changes in organisms that significantly provide evidence for constructing a timeline of the earth’s history.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?
A. There are variations in their RNA sequences.
B. The leaves and flowers show morphological differences.
C.They produce viable but sterile offspring.
D.They occupy unique habitats in an ecosystem. .
Answer:
the answer is C
Explanation:
Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.
The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.The biological concept of species states that mating between individuals of the same species produces viable offspring.The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

What is a kingdom?In biological classification, a kingdom is the second highest taxonomic rank below domain. It is used to group organisms based on their similarities and differences in characteristics and traits. The system of classification, known as Linnaean taxonomy, categorizes living things into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
Each kingdom is defined by specific characteristics such as cell structure, mode of nutrition, and reproductive strategies. For example, the Monera kingdom consists of unicellular organisms with prokaryotic cells, while the Plantae kingdom includes multicellular organisms that produce their own food through photosynthesis.
The kingdom level of classification helps scientists understand the relationships and diversity of living organisms, which is important for fields such as ecology, evolutionary biology, and biotechnology.

what errors that could take place if a cell in m phase and g phase combine
Answer:
Explanation:
If a cell in the S phase come together and joined with a cell in the G1 phase, the nucleus of the G1 phase will suddenly jumped into S phase and this will result in the synthesis of DNA . If a cell then in the M phase joined with a cell in G1 phase, the nucleus of G1 will undergo mitosis and this will lead to the formation of a spindle and chromatin condensation even when duplication of chromosomes has not occur.

Choose the statement below that is true. Photosynthetic enzymes are denatured at high temperatures. Increasing temperature always increases the rate of photosynthesis. Too much carbon dioxide is toxic for plants. The main limiting factors are temperature, light intensity and oxygen concentration.
Answer:
The correct answer would be -
Photosynthetic enzymes are denatured at high temperatures
Too much carbon dioxide is toxic for plants
Explanation:
Temperature is a limiting factor for the rate of photosynthesis due to the fact the at high-temperature photosynthesis is affected as initially with an increase in temperature rate of photosynthesis but after a limit, it becomes constant and increasing above that will result in denaturing of the photosynthetic enzymes.
CO2 is also a limiting factor that limits the photosynthetic rate if too little or affects the photosynthesis in the too much amount by denying the O2 intake by soil and make leaves thick.

What is the process represented by this diagram
Answer:
Photosynthesis
Explanation:
The process described in the image attached to the question above is PHOTOSYNTHESIS, which is the metabolic process whereby plant cells manufacture their own food in the presence of a light source (sunlight) for energy. Photosynthesis occurs in the chloroplast of plant and algae cells.
Photosynthesis occurs in two stages namely; light-dependent stage and light-independent stage. The light dependent stage synthesizes ATP and NADPH molecules needed by the next stage to produce sugars.
According to the image portrayed in this question;
- Letter A represents the LIGHT ENERGY source.
- Letter B represents WATER while K represents OXYGEN gas given off
- Letter F represents thylakoid lumen where the first stage occurs while letter G represents the stroma of the chloroplast where second stage occurs.
- Letter C represents carbon dioxide (CO2) while letter L represents glucose molecule.
