Dolphins chasing and eating fish would be an example of what type of relationship?
Group of answer choices
Predation
Competition
Mutualism
Parasitism
Answer:
predation, because it is a predator and prey
Explanation:
Dolphins chasing and eating fish would be an example of a predation relationship. This is because dolphins are the predator of all such small fishes which are living simultaneously.
What do you mean by Predators?Predators may be defined as the organisms that hunt or kill other organisms, particularly for food.
Predation is a type of interaction where one species is benefitted in the presence of another species, while the other species is harmed or lost in the presence of the first species.
Therefore, dolphins and other fishes show predation interaction.

A. fragments of other rocks B. chemicals and minerals dissolved in water C. sea shells D. all of the above
Answer:
D: All of the above
These are all sources for sediments
The correct option is D. all of the above are a source of sediments.
What are sediments?
According to geologists, sediment is any solid Earth surface material that can be transferred and dumped in a new location, whether it be on land or in water.
Because sediment particles are easily picked up by water, wind, and ice and transported to new locations, erosion is a significant driver of sediment mobility.
Pebbles and gravel are deposited further downstream, notably in lowland deltas where river mouths open up to the ocean, as water runs over land and through the creek and river basins.
Therefore, The correct option is D. all of the above are a source of sediments.

Each parent gives one of these to the offspring to form a genotype.
Answer: Alleles
Explanation: Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Each parent gives one ALLELE to the offspring to form a genotype.
An allele is a gene variant. which is inherited from each parent.
During fecundation, each parental gamete provides a different allele of a given gene/locus in order to form the genotype of an individual.
If both parents provide the same allele of a given gene/locus, then the individual is homo-zygous for that gene.
If both parents provide different alleles of a given gene/locus, then the individual is heterozygous for that gene.
In conclusion, one allele is inherited from the mother and the other allele from the father.

Answer:
D . The atomic number and atomic mass decrease from left to right across a period;
energy levels increase from top to bottom down a group.
Explanation:
On the periodic table, elements are arranged based on the periodic law. This law states that "the properties of elements are a periodic function of their atomic number".
The atomic number is the number of protons in an atom.
Atomic mass is the number of protons and neutrons in an atom
The energy level is the number of shells in an atom
As we move from left to right on the periodic table, both atomic mass and atomic number increases. Also, down a group, the energy level increases as the number period increases. From left to right, the energy level stays the same.Which of the following BEST defines the process of observing

chemical reactions that _______ energy often occur spontaneously
Answer:
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without a source of energy. An example of an energy-releasing reaction is hydrogen gas burning, or reacting, with oxygen to produce water vapor. direction the reaction requires energy.
Explanation:
thank me later
Chemical reactions which release energy often occur spontaneously whereas reactions absorbing energy do not occur spontaneously.
What are chemical reactions?Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.
There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical reactions:
1) inorganic reactions
2)organic reactions
3) biochemical reactions
During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

The mass of cells formed a result of accelerated rate of division is called tumour.
CELL DIVISION:
All living cells are capable of replicating themselves and this is done via the process of cell division. However, the rate at which cell division occurs must be regulated.Due to series of reasons like mutation, cells can lose the ability to regulate their cell cycle leading to a proliferation in the rate of cell division. Uncontrollable increase in the rate of cell division leads to the formation of a mass of cells called TUMOUR.
