How can an octopus be able to fit its entire body into any space it finds regardless of its size

Answers

Answer 1
Answer: Octopus are invertebrates hence, they obviously lack spinal column and other major bones that forms the structure of their body, and that said they only compose more of muscles that can contract and expand which makes them able to move from space to space with ease regardless of size and position. Their bodies adapt to such change but only for a durationed time.

Research indicates that dreaming may be responsible for inspiring creativity by __________.A. stimulating beta waves, which are responsible for waking brain activity

B. rehearsing the daily activities for which one may need preparation

C. allowing for the emergence of old data in useful, new patterns

D. giving the brain long periods of rest where it is not overworked

Answers

Answer: Option (C) is the correct answer.

Explanation:

Dreams are the desires or goals that an individual wishes for himself and wants to achieve.

Therefore, the old data in our mind which is not fulfilled or achieved generally takes the new shape in our mind and we tend to become creative in order to fulfill that desire or data.

Therefore, we can conclude that research indicates that dreaming may be responsible for inspiring creativity by allowing for the emergence of old data in useful, new patterns.

The cladogram below was created to show the evolutionary relationships between different vertebrates.Which of the following inferences can be made, based on this information?

a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
b. Birds and sharks do not share a common evolutionary ancestor.
c. Having a bony skeleton did not provide an evolutionary advantage to sharks or ray-finned fish.
d. Rabbits and primates diverged more recently than crocodiles and birds.

Answers

Answer: a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.

Explanation:

A cladogram is a diagrammatic representation of the phylogenetic relationship of recently evolved species with their common ancestors. The relationship is defined on the basis of genetic, molecular, morphological make up of the organisms. The node in the cladogram defines a divergence or difference between the two taxon.

Birds and amphibians share a more recent common ancestor than shark and birds because they can be seen lying closer at the terminal ends of the cladogram.

The answer for the given question above about a cladogram showing the evolutionary relationships between different vertebrates is option A.  Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds. I hope this helps.

This type of reproduction produces variety in species.Sexual reproduction
Asexual reproduction
Mitosis
Cloning

Answers

Sexual Reproductions (i.e. Meiosis)


In Meiosis you have a crossing over stage in prophase I, which will result in the exchange of genetic material + the random assortment at metaphase 1 and 2 increases the variety.

There is approximately 10 billion different ways that a child can look from a mixture of the paternal and maternal genes due to all the random events that happen in meiosis/ sexual reproduction.

Answer:Which process produces the most variation within a species?

A. Asexual Reproduction

B. Sexual Reproduction

C. Mitosis

D. Cloning

Explanation:

B/Sexual reproduction

How do mitosis and meiosis differ in the division of genetic composition?

Answers

Mitosis is where the chromosome are separated in 2 identical sets of chromosomes and end up with it own nucleus. Meiosis is the division in 1/2 and then in 1/2 again causing 4 identical sets of chromosomes. Hope this helps! If something does not make sense let me know and I will be glad to explain! ;)
