Which of the following observations helped Darwin shape his concept of descent with modification?

Biology
1 answer:
Zarrin [17]3 years ago
4 0

Answer:

The correct answer will be option-D.

Explanation:

Darwin is best known for his theory of evolution which he proposes after collecting the specimens of plants and animals on his voyage.

He observed the similarity and differences of the morphological pattern as well as the species present in the area. On the basis of his conclusions, he suggested that organism get traits from their parents and species to change over time also called descent with modification.

One of the evidence that supported his concept is that he observed plant species in South America and found that these species closely resembled the species of the tropical regions of South America rather than species of the temperate region of Europe as the habitat was same.

Thus, option-D is the correct answer.

Describe the cell membrane, cell wall, nucleus, and cytoplasm. which of these structures are you likely to find in a prokaryotic
Morgarella [4.7K]

Answer:

you can see below

Explanation:

Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

Eukaryotic cells

have plasma membranes

please mark me brainliest or mark me thanks at leat

only have cell walls if the cells are plants.

They do have a nucleus.

They have cytoplasm

Prokaryotic cells

have plasma membranes

cell walls are usually chemically complexed.

don't have a nucleus

have cytoplasm

Animal cells

only have the plasma membranes.

No cell wall

have a nucleus

have cytoplasm

Plant cells

have both the cell wall

and have a plasma membrane

have a nucleus

have cytoplasm

How are mammalian sperm cells produced and incubated at a lower temperature than boday temperature ?
Morgarella [4.7K]

Answer:by being produced in the testes outside the body

Explanation: spermatogenesis is the production of male gamates,the sperm.this process occurs in the seminiferous tubules in the testes.epithelial cells produces the primary spermatocyte which divides to give a secondary spermatocyte.

The secondary spermatocyte divides to form spermatids,which differentiates to form the spermatozoons.

Testis is housed in the scrotal sac.

Sperm production is sensitive to temperature. Too high temperature can cause formation of abnormal cells . As a result the scrotal sac is located outside the body
