The effect that malnutrition have on the fetus during critical development in pregnancy is that the impairment of the development of an organ is irreversible. Maternal malnutrition can adversely affect the division and replication of cells in the embryo at this stage, impairing its development. The effects of malnutrition during critical periods of pregnancy are seen in defects of the nervous system of the embryo, poor dental health among other effects.
Answer:
An index fossil is also known as guide fossils or indicator fossil. They are fossils used to determine and identify geologic periods.
The main characteristics of an index fossil include :
1.It must be distinctive.
2.It must be widespread.
3. It must be abundant
4. It must be limited in geologic time.
Due to trends and studies of most fossil-bearing rocks being formed in the ocean, the major index fossils are mostly marine animal or plant organisms.
Hi there!
We can go through the overall function of all three of these:
mRNA: transcribed from the DNA, has the protein's composition written in it, and brings that to a ribosome where the protein will be made
tRNA: looks at the codons (set of 3 nucleotides) on the mRNA and brings amino acids which match up to that codon
rRNA: significant part of the composition of ribosomes
Now, looking at these, and back to the answer choices, we can already see that a, b, and c are correct. d, on the other hand, is incorrect.
Hope this helps! Feel free to let me know if you have any questions about this specific problem.
Answer:
c and d
Explanation:
<u>A species of an organism with cell wall that lacks peptidoglycan is definitely not a bacterium because bacterial cell walls usually have peptidoglycan.</u>
One particular group of organisms whose cells have cell walls but lack peptidoglycan is Archaea.
<em>Archaea represents a group of prokaryotes that are able to survive in extreme conditions such as high temperature, pressure and salinity. As such, they could inhabit hydrothermal springs as well as alkaline hot springs.</em>
Hence, thermoacidophile <em>Sulfolobus acidocaldarius </em>is likely to be an Archaea and could inhabit both hydrothermal springs and alkaline hot springs.
The correct option is option c and d.
Answer:
chloroplasts
