Answer:
Jennifer should understand that exposure to teratogens can cause the most damage during exposures such as <em>the duration of exposure, the amount of teratogenic substance, and the stage of development the embryo or fetus is in during the exposure. </em>
Explanation:
<em>Teratogens</em> may affect the embryo or fetus in a number of ways, causing physical malformations, problems in the behavioral or emotional development of the child, and decreased intellectual quotient (IQ) in the child. Additionally, <em>teratogens</em> may also affect pregnancies and cause complications such as preterm labors, spontaneous abortions, or miscarriages. <em>Teratogens </em>are classified into four types: physical agents, metabolic conditions, infection, and finally, drugs and chemicals.
Answer:
The energy that was not passed on the next tropic level is lost as heat
Explanation:
In an ecosystem flow of energy occur from one tropic level to the next one as the organism of one tropic level eats another organism belongs to the tropic level that is lower from that of previous one.
The 10% of total energy of one tropic level is passed to the next tropic level the rest of the energy is lost as heat in the environment.

Answer: Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA
Explanation:
Cells are the smallest functional unit of organisms which are classified under two main categories namely:
--> prokaryotic cells and
--> eukaryotic cells.
Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.
Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.
From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.
