How do nuclear fusion and fission differ

Answers

Answer 1

Answer:

Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Sally and Maria hypothesized that earthworms lived only in dark, damp places. They measured a one-meter square in a shady spot near a stream. They dug through the soil and collected earthworms. They collected 43 worms. They repeated the experiment in several locations, sunny and dry included. They found the most worms in the shady, damp plot near the stream. Several other groups of science students carried out the same experiment and got similar results. This is an example of A) bias.
B) repetition.
C) replication.
D) validity.

Answers

Answer: C) replication.

Explanation:

Replication in experiments is the process by which the entire experimental process is repeated as done by the previous scientists, keeping in mind all the necessary requirements and experimental conditions so as to determine the correctness of the experimental methodology, relationship between the variables, correctness of the results and other parameters.

Here, several group of students are repeating the same experiment and getting the same results this process is called as replication.

because other scientists did the experiment and got the same results it's replication. the other group replicated the experiment and we're able to replicate the results

Which of the following is NOT a major characteristic used to identify minerals? a. hardness c. density b. magnetism d. luster Please select the best answer from the choices provided A B C DI know it is not d

Answers

Answer: Option B

Explanation:

The characteristic such as magnetism is not used as a characteristic to identify minerals is magnetism.

This is because most of the minerals do not posses this character only few minerals have this property.

The character such as density, hardness and luster are some of the physical property which is used to classify the substance as mineral.

hence, the correct answer is option B

The answer is magnetism (B)

This lipid is amphiphathic . Because of this, this lipid A) contains no double bonds between carbons and is a solid at room temperature. B) contains varied functional groups to create molecules with varied functions. C) has a polar and non-polar region, making it a logical component of cell membranes. D) contains at least one double bond between carbons and is therefore, liquid at room temperature.

Answers

Answer:

The correct answer is C has polar and non polar region making it logical component of the cell membrane.

Explanation:

Amphiphatic compounds are specific type of biochemical compound that contain both polar and nonpolar portions.

For example phospholipid molecules of the lipid bi layer of the plasma membrane.Phospholipid contain polar head group also called glycerol and 2non polar hydrocarbon fatty acid tails.Therefore lipid basically phospholipids are amphiphatic in nature.

IT'S VERY IMPORTANT PLEASE HELP!In a species of dogs, a black coat is dominant over a white coat. The offspring from a black dog and a white dog all have gray coats. This is an example of _____.
incomplete dominance
complete dominance
codominance
sex-linked genes

Answers

The correct answer is A. Incomplete dominance

Explanation:

Incomplete dominance occurs in genetics when two alleles lead to a new observable trait (phenotype), this occurs because the two alleles (variants of genes) combine or express at the same time, and therefore neither of the alleles shows a complete dominance. This type of dominance differs from codominance because in codominance both alleles express equally without combining or creating a new phenotype.

The case presented is an example of incomplete dominance because the allele that leads to black coat and the one that leads to white coat are combining, and therefore none of the alleles is completely dominating; also, in this case, there is a new phenotype or trait, which is the gray coat of the offspring that results from combining black coat and white coat alleles.

Incomplete dominance
