There are 4 different (main) types of tissue: Muscle, Connective, Nervous, & Epithelial.

(if you need a different example here's one): The Doctor did surgery on the patient to see what was wrong with her tissue.

How much chemical energy (stored as biomass) is available to primary consumers from 10,000 kcal of primary productivity?

atroni [7]

The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.

If an error occurs during the replication process, that error would be passed on to all subsequent daughter strands, resulting i

Stels [109]

Answer:

The correct answer is: Mutation.

Explanation:

Mutation can be defined as a phenomenon due to which the nucleotide (DNA or deoxyribonucleotide) sequence present in the genome of an organism gets altered.
Mutation can occur because of various factors like error-prone replication (DNA polymerase fails to proofread and incorporate the correct nucleotide in the daughter strand), improper DNA repair, exposure to mutagens (that causes mutations like Ultraviolet rays or UV rays that causes the formation of thymine dimer in the DNA), exposure to mobile genetic components like Transposons.
The different types of mutations with respect to their effect on the DNA sequence are:

Indel mutations: Also called Insertion Deletion Mutations where large sequences of DNA are either incorporated or removed from the genome. If such a mutation occurs in the protein coding region of a gene, then no functional protein can be obtained from such a gene.
Base substitution: Here the required nucleotide in the DNA sequence is replaced with some other nucleotide during the process of replication. If this happens in the wobble nucleotide of a codon (the last nucleotide in the triplet codon. A Codon is responsible for encoding for an amino acid. Due to degeneracy of the genetic code, multiple codons can encode for a particular amino acid), that would not affect the protein sequence but if it happens in the other two nucleotide of the codon it can cause change in the amino acid sequence of the protein, resulting in a non-functional protein.
Silent Mutation: Where the mutation has occurred either in the non-protein coding region of a gene or in the wobble nucleotide of a codon such the amino acid sequence does not get altered.
Non-sense Mutation: Where the mutation is such that a stop codon is introduced in the middle of the protein coding region of a gene. Hence, a truncated non-functional protein can be produced from such a gene.

Which of the following statements best describes a benefit of sexual reproduction?

Ivan

Among the listed options, we can conclude that option C which states that "It results in the diversity of the species that enhances the probability of survival." is correct.

Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is better adapted to a changing environment and promotes the faster evolution of a species.

The main benefit of sexual reproduction is that it allows for a greater diversity of the species which enhances the probability of survival. This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (the ability of a member of the species to choose a spouse with desirable traits) leads to offspring who over time are increasingly better adapted to life in the given environment, with specific traits tailored for survival.

A molecule in which one or more atoms or end is slightly negative and one or more is slightly positive.

monitta

When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
