The right answer is A.

- Thermal conduction is specific to solids (such as soil, rock, wood, metals, etc.), it is a direct transfer within a material medium, which is done by spreading from near to heat. The thermal agitation motion (heat flow) always goes from hot areas (rock or sand) to cold areas (the alligator).

What information can a scientist learn directly from a single fossil? A. The organism's shape and size B. The life expectancy of
Elena L [17]

C. How the organism is related to others

Explanation:

From a single fossil, a scientist can learn how the organism is related to others. Fossils are the preserved remains of organisms that are usually found in rocks.

  • Organisms must posses certain characteristics to ensure their preservation as fossils.
  • Most organisms that are preserved usually have hard parts.
  • Some climatic influence can also arrest decay and provide a platform organisms to be preserved wholly.
  • Fossils are used for relative dating of events in nature.
  • They can also be used to determine how an organism is related to another.
  • This is called phylogeny. It is the study of evolution and how organisms relates to one another.
  • Fossils are very good and useful phylogenetic tools.

Autosomes are _______ chromosomes. <br> A. haploid<br> B. homologous<br> C. nonsex<br> D. abnormal
Vera_Pavlovna [14]
<span>Autosomes are non-sex chromosomes, meaning they are non-sex determining chromosomes inside cells. Humans naturally have 46 chromosomes in each body cells; 44 of these are actually autosomes that a person inherits from his/her parents. All persons get 22 autosomes from the mother and the other 22 autosomes will be coming from the father. These autosomes always come in pairs and since everyone has 44 of these autosomes in their cells, it should be noted that there are only 22 types that are obviously numbered from 1 to 22. </span>

In 1838 botanist Matthias Schleiden determined that all plants are composed of cells. In 1839 anatomist Theodor Schwann proposed
TiliK225 [7]

Answer:

This question lacks options, the options are;

A. All cells have a cell wall.

B. All cells arise from pre-existing cells.

C. All cells are capable of photoshynthesis.

D. All cells can develop into any other type of cell.

The answer is B.

Explanation:

The widely accepted universal cell theory is known to be contributed to by three scientists viz: Matthias Schleiden, Theodor Schwann and Rudolph Virchow.

As rightly stated in this question, Botanist Mathias Schleiden and Zoologist Theodor Schwann proposed that plants and animals are made up of cells in the year 1838 and 1839 respectively. However, in 1855, biologist Rudolph Virchow expanded the cell theory by adding that all living things are composed of cells and that these cells arise from pre-existing cells.

The collaboration of these three scientists brought about the cell theory that states:

* Cells are the basic unit of all living things.

* All living things are made up of one or more cells.

* All cells arise from pre-existing cells.
