Answer:

  1. T. Natural Reseeding.
  2. D. Species Diversity
  3. A. Ecosystem Diversity.

Explanation:

Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.

Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.

What do we call the process where part of the DNA is saved during replication?
Nataly_w [17]

Answer:

The process where part of the DNA is saved during replication is known as semi conservative replication.

Explanation:

During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid).  When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied  during the cell  division cycle.  During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus of a cell during the s stage  of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.

Tapeworms can reproduce by _____.<br> budding<br> fission<br> fragmentation
Tema [17]
Binary fission is a type of asexual reproduction or rather an asexual reproduction common in most prokaryotes.
This function happens when the organism divides itself producing another replica of its genetic material and now altogether as the organism itself.

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reprod
Lunna [17]

Answer:

Reproductive cells have half the amount of chromosomes than body cells

Explanation:

I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.

For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.

In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.
