Answer:
This question lacks options, the options are:
a. Their size
b. The chemical composition of the cell wall and cell membrane
c. Their ability to grow at high temperatures
d. The shape of their mitochondria
The answer is B
Explanation:
Living organisms has been classified into three domains namely; Eukarya, Archaea, and Bacteria. However, domians Archaea and Bacteria are most similar in the sense that they both have cells without a membrane-bound nucleus, hence, they are both PROKARYOTIC. Also, they are both strictly unicellular organisms.
Despite these similarities, differences exists between them. One major difference is in the chemical composition of the cell wall and cell membrane. The cell walls of bacteria cells have a unique structure called PEPTIDOGLYCAN. This is absent in the Archeae group. Also, the cell membrane of Archeae is made up of ether linked lipids compared to the ester-linked lipids that constitutes bacteria cell
Answer:
e. the amino acids serine, histidine, and aspartate
Explanation:
Chymotrypsin is a digestive proteolytic enzyme secreted in the duodenum by the pancreas. It is a member of the serine proteases with active sites containing serine, histidine, and aspartate which it uses to cleave through hydrolysis (addition of a molecule of water) the c-terminus of aromatic amino acid tryptophan, tyrosine, and phenylalanine on peptide chains. Its hydrophobic pockets makes it suitable for aromatic amino acids.
Some key reasons for partially developed offspring:
• Genetic issues, parents sexual organs incorrectly formed, in turn malforming the offspring
• Pollution, parents consuming something they shouldn't have while the offspring was developing
• Breeding between relations; accidently mating with a brother or sister, in turn causing defects as many of the genes are the same
The statement 'the loss of plant species and habitats will lead to widespread animal extinction' is TRUE.
<h3>What is biodiversity?</h3>
The term 'biodiversity' refers to all types of diversity in the tree of life (e.g. phenotypic and genetic diversity).
Plants are producer organisms that sustain many different ecosystems and the biodiversity in these areas.
The loss of biodiversity (extinction of species) may completely disrupt an ecosystem in an irreversible way.

a. What is a star's spectrum?
A star's spectrum refers to the <em>"amount of light"</em> that stars they give off according to varying wavelengths. Since we cannot tell the amount of light a star gives off quantitatively from Earth, we can differentiate them according to how bright they appear.
b. Which spectrum is most common in stars?
Stars are classified according to their spectra <em>(elements in the star)</em>. They are classified into 7 types <em>(O, B, A, F, G, K and O). </em>The most common type is M, however, it gives off a dim light.
c. How can it differ from start to star?
Although stars follow a continuous spectrum, the spectra of a star differs from each other because <u>they do not give off the same amount of energy at the different wavelengths. </u>
d. What does the spectrum tell us about the star?
The spectrum can tell the<em> surface temperature</em> of the star. This means that a blue star (we often see it as a white-colored star from Earth) is hotter than that of a yellow star. A red star is considered the coolest star among all.
The spectrum of stars also allows the astronomers to study composition of the stars according to their <em>wavelengths.</em>
