The crab is a natural predator to the snail. Overtime, the shell of the snail has become thicker and spinous to deter the crab’s predation. The evolutionary response to this would most likely be that the crab species will become extinct because they have no food source. the snails will thrive and the predator/prey relationship will swing back. the crab will find a new organism to prey upon. the crab will evolve to have more powerful claws.

Answer: the crab will evolve to have more powerful claws.

Explanation: Evolution is the change in the characteristics and features of a species over generation which develops due to natural selection and adaptation within the course of time. The predator is an organism which kills other organism to obtain it as food. The prey is an organism which is killed by the other organism.

According to the given situation, if the prey develops special adaptations to prevent itself from the predator. The predator will also be evolved so as to obtain prey as food. Therefore, the crab will evolve to have more powerful claws is the correct option.

Question

obtain and use energy grow and develop reproduce respond to their environment These items may be classified as ? B) characteristics of animals C) characteristics of insects D) characteristics of living things

Solution 1

Answer:

D (characteristics of living things)

Explanation:

All things in existence are made up of matter, which can either be living or non-living depending on whether or not they have LIFE in them. This means that the possession of life distinguishes a living thing from a non-living thing. This life that living things possesses makes them able to perform certain functions called their characteristics.

Based on these, the characteristics of living things have been summarized into an acronym called MR NIGER D with each letter meaning a particular characteristic.

M- Movement (ability to move)

R- Reproduction (ability to produce young ones)

N- Nutrition (ability to absorb nutrients)

I- Irritability (ability to respond to stimulus in the environment)

G- Growth (ability to increase in size, weight and height)

E- Excretion (ability to pass out waste products from the body)

R- Respiration (ability to obtain energy)

D- Death (ability to die)

Looking at all these characteristics, they are possessed by insects, plants, animals, humans etc. Hence, they are all grouped as living things.

Solution 2

I think it is d - as plants animals and insects etc all do this

Question

In a typical population of gazelle, the average birth rate is 25 new fawns each spring. However, this spring there was a significant increase in the amount of fawns birthed to 150. This drastic increase led to food being depleted, an overproduction of waste, and many in the population died as a result. Which condition for natural selection was at work in this case? A) Inherited variation B) Mutation C) Overproduction of offspring D) Evolution

I think it is c but I’m not 100% sure so wait for someone else to answer too maybe ?

Question

which of the following is not true about performing biological investigation.. A. reading and understanding the steps bfore conducting an experiment is necessary for safety. B.scientists are trained to conduct their investigations safely. C.the metric system and the revised SI are based on multiples of 10. D.most scientists do not use the metric system or SI

Solution 1

The answer is the option D. It is false that most scientist do not use the metric system or SI. SI, the international system was adopted many years ago. It was an evolution of the metric system. In 1960 a commite of international scientists adopted it. Since then, the SI has spread widely and it is a must for the scientist to use it.

Question

Which system is BEST described by the functions listed below? 1. Gather internal and external sensory input 2. Process the input 3. Respond to the input A. the nervous system B. the respiratory system C. the immune system D. the circulatory system

Solution 1

It is a)The nervous system

Question

In what way is DNA like a book? A. DNA has information organized with a kind of index B. DNA has stored information that can be copied and passed on C. DNA has information wrapped in an identifying cover D. DNA has information that is periodically updated

Solution 1

I think that the answer is A: DNA has information organised with a kind of index. Because a book contains letters- just like the DNA. It's how the letters are arranged into words and that's is what gives the book a meaning/significance. The same is for DNA. It is how the bases are arranged that makes them significant.

Question

possible rationales that taxonomists might have used when deciding to group prokaryotes into two distinct domains instead of in one group

Solution 1

For a long time, there was only one group of prokaryotes that was recognized by the scientific community, the bacteria. But, with the development of the methods of molecular biology and genetics, it became evident that the archaea are quite different than bacteria and should be regarded as a separate domain.
Even though they are both prokaryotes, lacking the organelles in the cell, the structure of the membrane of archaea is different from both the bacteria and the eukaryotes. Furthermore, analysis of the genomes of the 3 domains proved that the archaea are truly a separate group, having some genetic similarities with both eukaryotes and the bacteria.

Question

How do viruses reproduce?

Solution 1

By attatching to a host cell and injecting their nucleic acid into the host cells chromosome, then they can either stay dormant or the will take over the cell, reproduce and then burst out of the cell which kills the host cell.

Question

Which enzyme do scientists use to bond a new gene to plasmid DNA? a. dna polymerase b. dna ligase c. rna polymerase d. restriction endonuclease

Solution 1

DNA ligases are used for bonding a new gene.
In a process of DNA cloning, the gene of interest is inserted into the DNA plasmid of bacteria. Different enzymes are used for different steps of this process. For example, restriction enzymes are enzymes used for cutting the DNA and DNA ligases are used for joining together different DNAs. Such plasmid (with a new piece of DNA) is inserted inside the bacteria in the process called transformation.

Answer:

DNA ligase

Question

Summarize the structure of DNA. Include information about the nitrogenous bases, sugars, and composition of the backbone. Which nitrogenous bases pair up together in DNA? RNA? Explain where covalent and hydrogen bonds are located. Also, fully explain the process of the central dogma (DNA, RNA, Proteins) in correlation of protein synthesis (DNA transcription and translation).

Solution 1

In DNA, Cytosine pairs with Guanine, and Adenine pairs with Thymine. In RNA, the same principle applies only that RNA has no Adenine base but Uracil. Therefore, Thymine pairs with Uracil while, similar to in DNA, Cytosine pairs with Guanine.

Covalent bonds occur in virtually all the bonds except between nitrogenous base pairs of opposite strands of DNA.

The central Dogma stipulates that DNA --à RNA--àProtein. During transcription, information on DNA is copied to messenger- RNA. In eukaryotes messenger- RNA moves to the cytoplasm where it is then translated to protein by ribosomes. In prokaryotes, since there is no nucleus, the mRNA is translated even as transcription continues.

Solution 2

DNA backbone is made up of deoxyribose monomer sugars as the basic unit that are covalently connected in chains. Each deoxyribose sugar is a five (5)-carbon ring. The 5’ carbon covalently bonds with a phosphate while the 3’ carbon bonds to the next deoxyribose carbon ring. The 1’ carbon is covalently bonded to a nitrogenous base (either Adenine, Thymine, Cytosine, or Guanine ).In DNA, Cytosine pairs with Guanine, and Adenine pairs with Thymine. In RNA, the same principle applies only that RNA has no Adenine base but Uracil. Therefore, Thymine pairs with Uracil while, similar to in DNA, Cytosine pairs with Guanine.Covalent bonds occur in virtually all the bonds except between nitrogenous base pairs of opposite strands of DNA.The central Dogma stipulates that DNA --à RNA--àProtein.
