Why can’t bears , tigers and lion live together

Answers

Answer 1

Answer: Because they would kill each other

Answer 2

Answer:

Answer:

Bears, lions, and tigers all are predators that have similar hunting habits such as medium to large prey. Because of this, if they were living in the save environment, they would be competing for food and space. This would cause them to attack and kill off each other until one remained. That or the other two species would be driven out of the area.

C. It is a teaching activity that uses students' personally owned dogs and cats.
D. There are no circumstances in which animal work may begin before IACUC approval.

Answers

Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)

Explanation:

The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.

SNP is an acronym for:A. simple Northern probe
B. sample in situ probe
C. simple nucleotide probe
D. single nucleotide polymorphism polypeptide
E. sequence normal

Answers

Answer:

single nucleotide polymorphism

Explanation:

A SNP (above) is a mutation in DNA at exactly one nucleotide (A, T, C, or G) that is present in at least 1% of the population.

For instance, let's say a certain protein relies on the sequence -TTG- at a certain position in a gene. If the sequence -ATG- is seen in that exact position in the gene (the A residue replacing the first T residue) in at least one percent of the population, this would be a SNP. If this replacement were in less than one percent of the population, it would just be a mutation.

Like DNA, RNA follows base-pairing rules. Experiment to find which RNA _____________ on the right side of the Gizmo will successfully pair with the thymine at the top of the template strand of DNA.

Answers

Answer: Nucleotide; Adenine

Explanation: RNA Nucleotide contains bases of Thymine, Cytosine, Guanine and Uracil. The Uracil base in RNA, substitute the base Thymine in the DNA base and bonds with Adenine like as seen in DNA base pairing.

Thus, during DNA duplication, the thymine at the top of the template strand of DNA is replaced with Uracil and binds with Adenine.

In asexual reproduction, only one parent contributes to offspring. The offspring aregenetically identical to the parent and with one another. The process involves mitosis but not
meiosis. Describe some of the advantages and disadvantages of sexual reproduction
