Answers

Explanation:

Predation plays an important role in the overall health of an ecosystem since it regulates the population of preys as well as maintain the population of higher-level consumers. If predators were eliminated from an ecosystem, it would cause an increase of the population of preys and potentially decrease the population of other organisms on lower trophic levels. An example of such effect can be seen from the population of rabbits and plants supposing that foxes, eagles and snakes are eliminated from the ecosystem. The rabbit population will multiply, causing a decrease in the population of plants such as grass that rabbits feed on.

The marine biologist from the nursery is planning to develop a large number of new coral polyps with large stinging tentacles. Identify the type of reproduction the marine biologist should use to develop the new coral and explain why this type of reproduction is preferable.

Answers

Answer:

Sexual reproduction.

Explanation:

Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.

When the genetic material found within an offspring is diverse, what type of reproduction is responsible?

a
Sexual reproduction, because the genetic material comes from both parents
b
Sexual reproduction, because the genetic material comes from one parent
c
Asexual reproduction, because the genetic material comes from both parents
d
Asexual reproduction, because the genetic material comes from one parent

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.​

Answers

Answer: A.

Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.

Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

A scientist is observing a gymnosperm. It is a desert shrub with needle-like leaves. The shrub has a deep root system and produces cones. Which gymnosperm is the scientist most likely observing?
A. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can grow as shrubs in deserts.
B. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can have needle-like leaves and deep root systems.
C. She is observing a ginkgo because, unlike other gymnosperms, ginkgoes can grow as shrubs in deserts.
D. She is observing a ginkgo because, unlike other gymnosperms, ginkgoes can have needle-like leaves and deep root systems.

Answers

Answer:The answer is B

Explanation:I took the test

The scientist is observing a gnetophyte because unlike other gymnosperms, gnetophyte can have needle-like leaves and deep root systems.

What are gymnosperm?'Gymnos' means 'n aked' and 's perm' means 'seed'.It reproduces by means of an exposed seed or ovule.They do not produce fruits and flowers.What are gnetophyte?They belongs to gymnosperm.Their leaves become needle-like to reduce transpiration.They are vascular plants.The reproductive structure are contained within cones.

Hence, the correct option is B. She is observing a gnetophyte because, unlike other gymnosperms, gnetophytes can have needle-like leaves and deep root systems.

Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.

Answers

The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.

What is transcription?

The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.

In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.

This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.

The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.

Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.
