Answer:
The activation energy depends on reactive species.
Explanation:
The minimum amount of energy required by the reacting species in order to start a specified reaction is called activation energy. Without activation energy, the reaction can be started so activation energy is very important for occurring of a chemical reaction. There are different amount of activation energy is needed to start different chemical reactions so we can conclude that activation energy depends on the type of reactive species and on the reaction.

What might happen to an enzymes activity if the gene encoding its production was altered by a mutation?
Answer:
The enzyme's activity will be altered
Explanation:
Genes are unit of hereditary that carries genetic information needed for the survival of the cell and organism at large. Genes are expressed via transcription and translation processes to produce a protein, which is responsible for the physical traits we can see (phenotype).
Since ENZYMES that catalyze biochemical reactions in living cells are proteinous in nature i.e. are made up of proteins, this means that they are formed from the expression of genes. Hence, if the gene encoding the production of an enzyme is altered or changed due to mutation, then the activity of the resulting enzyme will also be altered (most times non-functional).
What type of scientists uses a dichotomous key?
Answer: biologists are a type of scientist that use dichotomous.
The Type of scientists that uses dichotomous key is : Biologist
A lot of scientists make use of the Dichotomous key for identifying unknown biological organisms like Biologists. A dichotomous key consists of a set of choices, with each choice consisting of two statements, these statements makes it possible to name an unknown biological organism.
A dichotomous key is a simply method used for the identification of organisms ( groups of unknown organisms are repeatedly divided into two groups to get more information about the organism )

Fill in the chart to compare asexual reproduction with sexual reproduction.
Answer: one parent, identical
one parent, different
Explanation:
Asexual reproduction involves a single parent parent who undergoes cell division and produces multiple identical offsprings. The asexual reproduction occurs in single celled organisms like yeast, amoeba, bacteria, and others. Sexual reproduction is a process in which two parents are involved which undergoes gamete formation. In sexual reproduction cell division occurs in both parents individually in the germ cells to produce the gametes the egg in female and sperm in male. When the fusion of egg and sperm occurs the organism so produced after development of fusion product that is zygote is different from both parents genetically and morphologically. Sexual reproduction can occur in both single celled (bacteria) and multicellular organisms (angiosperms, humans).

Which type of birds do you think survive the drought finches big breaks or finches with small beaks?
Answer:
Since large and hard seeds survived the drought, that means that finches with large beaks survived the drought. Finches with small beaks would not be able to eat the large seeds and would not survive.

Answer:
7. Recessive
8. Recessive
9. Dominant
10. Dominant
11.Dominant
12. Dominant
Explanation:
In genetics, an allele can be dominant or recessive; if there is complete dominance then the dominant allele will always be represented in the phenotype. The genotype of a person is two letters, either upper or lowercase, that represent the alleles an organism has for a certain trait. Uppercase alleles are dominant, while lowercase is recessive. So all of the lowercase letters should be recessive and all of the uppercase should be dominant.

View Available Hint(s) Over 1 million species of animals have been named and described by biologists. These species arose __________. before the Cambrian explosion through years of evolution as natural selection shaped animal adaptations to Earth's environments from island-bound populations of individuals as a result of evolution from a common fungal ancestor
Answer:
through years of evolution as natural selection shaped animal adaptations to Earth's environments.
Explanation:
Over the years, biologists have been able to successfully name more than one (1) million animal species across the world. These species arose through years of evolution as natural selection shaped animal adaptations to Earth's environments.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

How would this food web be affected by the extinction of the Osprey?
Answer:
The fish would grow in the population, because osprey mainly eat fish.
Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.
Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

When a substances like sugar, salt or lemon juice dissolve into a liquid and appears to "disappear", it is no longer present in the solution.
True
False
Answer:
False.
Explanation:
A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.
The molecules are still there.

What device is used to measure water forming on the glacial ice sheet?
The device that is used to measure water forming on the glacial ice sheet is known as the Airborne Topographic Mapper (ATM).
What do you mean by Glacial Ice sheets?Glacial ice sheets may be defined as a mass or accumulation of glacial ice of more than 50,000 square kilometers. This sheet significantly contains about 99% of the freshwater on Earth and is sometimes called continental glaciers.
According to the context of this question, an instrument known as the Airborne Topographic Mapper (ATM) considerably collects the elevation of the ice surface along with its thickness. Apart from this, it also measures the formation of ice from water on the glacial ice sheet.
Therefore, the Airborne Topographic Mapper (ATM) is a device that is used to measure water forming on the glacial ice sheet.
