Answer:

C

Explanation:

Volcanic eruption spews volcanic ash into the atmosphere that lingers and blocks out sunlight for months. This causes photoautotrophs to decrease in population numbers due to the inability to photosynthesize.  This will negatively affect the heterotrophs that depend on the autotrophs for energy.

Answer:

B

Explanation:

There are usually dominant and recessive alleles. The dominant alleles mask the expression of the recessive allele. Therefore, whenever an offspring has a dominant allele of a gene, it will be expressed whether in homozygous or heterozygous form.

Answer:

B

Explanation:

A limiting factor is an element whose abundance affects the growth and distribution of a population of a species in an environment. In this case, increasing the levels of Nitrogen in the environment increases the population size and vice versa.

Many bacteria reproduce asexually. the bacterium shown here is reproducing asexually, by binary fission. the definition of a ___
sergij07 [2.7K]

The correct answer is D. species.


The definition of a species is termed as a group of interbreeding individuals cannot be easily applied to organisms that they reproduce only or mainly by asexual methods.


Species is termed as the basic unit of classification and taxonomic rank and also unit of biodiversity. It is the largest group of organisms whereby two individuals produce fertile offspring.

They are typically by sexual reproduction. Boundary which is between closely related species they becomes unclear.

How can cells from the same organism have such different shapes and functions?
Savatey [412]

Answer: As each cell differentiates, the <em>DNA </em>changes so that each type of cell has different <em>DNA</em> once it reaches maturity. Mutations in the cells’ nuclei lead to new combinations of <em>DNA</em>, resulting in different shapes and functions in the different types of cells.

Hope this helps!

How do scientists use fossils to study climate?<br> PLS HELP
faust18 [17]

Answer:

Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.

What are the characteristics of stem cells
gavmur [86]

Answer:

Explanation:

Long-term Self-Renewal: Stem cells are capable of division while remaining unspecialized.

Differentiation : Stem cells can divide asymmetrically, where one stem cell divides into two cells that have different cellular fates.

Induced Pluripotency : Stem cells that have been artificially created from specialized cells are called induced pluripotent stem cells.

Considerations : Due to their unspecialized nature, stem cells have a large research potential. The most pluripotent stem cells derive from the human embryo.
