Question:

Which of the following pieces of evidence most strongly supports the idea that all life on earth evolved from a single ancient common ancestor?
a all life requires a constant input of energy from its environment
b all organisms use the same molecules (dna and rna) to function and reproduce
c all organisms reproduce themselves
d all organisms experience evolution

Answers

D All organisms experience evolution

Common ancestry is identified in the genes. Selection forces are the drives to these physical and composition changes of an organism however, it can be traced back.

Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. 

Actually its

Explanation:

A new generation that further develops the works of the old generation atleast in humans and if you talking about animals they start their own faimilies like their parents and work witha group to survive and start another generation through reproduction again.

Answer :

During diffusion, when the concentration of the molecules on both sides of the membrane is the same, the molecules will continue to move across the membrane in both the direction.

Answer 3 : It allows single-celled organism to reproduce, and other organism to repair damage tissues and grow.

Answer 4: The nucleus is an organelle that is surrounded by the cytoplasm, a jelly-like fluid.

Explanation :

Diffusion : It is a process where liquid moves from higher concentration to the lower concentration through permeable membrane.

When the concentration of the molecules on both sides of the membrane is same and the membrane is permeable membrane then diffusion will occur and the molecules will moves continuously across the membrane in both the direction.

Answer 3 :

Mitosis : It is a process of cell division. In this process, nucleus divides into two daughter cell and each daughter cell contains same number of chromosomes as present in parent nucleus.

The main purpose of the mitosis is to repair damaged tissues and growth.

Answer 4 :

Nucleus is a type of cell organelle. It is present in both animal and plant cells and it is the brain of the cell. It is present only in eukaryotic cell.

Nucleus is an organelle which is surrounded by the cell membrane which protects its from the other cells.

Cytoplasm is a jelly-like fluid which is present in the cell membrane which is made up of salt and water.


 

Both organisms exhibit a diploid stage and are only able to reproduce asexually.

C

Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.

Explanation:

Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes.  The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.

i think it is D

Explanation: they both reproduce asexually

I took this test 1 week ago and it's B.

It is Definitely A.) Both organisms produce haploid spores and exhibit diploid and haploid stages.

The answer is C

Explanation:

The answer is; A

In pteridophytes, the sporophytes (of the haploid stage) produce spores. The diploid stage in pteridophytes may occur when tow spores fuse and develop into a prothallus (diploid stage of the pteridophytes).

Fungo too produces spores by the sporangiophores (haploid stage). Occasionally, two horizontal hyphae between two species of fungi, may fuse at the tips and form a zygote through karyogamy and plasmogamy.
