Answer:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane.

The right answer is into sugars.
Photosynthesis aims to create energy (in the form of carbohydrate) from the
light energy from the sun. The organisms that use the photosynthesis
mechanism are phototropic because they make organic materials from
inorganic materials.
Answer:
have the same number of electron energy levels
Explanation:
All of the elements in the same period have the same number of atomic orbitals that are occupied by electrons that are in constant motion. For example the elements in the first period have one orbital for its electrons. The elements in the second period have two orbitals for their electrons. As you move down the table, every row adds an orbital. At this time, there is a maximum of seven electron orbitals.
Answer:
I.
Explanation:
The woman's father has haemophilia so his genotype must be XhY, so his daughter can only have the following genotype: XHXh. Her husband is not a haemophiliac so his genotype must be XHY. There is a 50% chance that the mother's gamete has the recessive allele for haemophilia. If she has a son that son will have a 50% chance of getting the Xh. This also applies to daughters, but they will get the normal allele XH from their father so the daughter will have a 0% chance of developing haemophilia.
<h3>Your answer is D.</h3>
The insects are the same species.
<h3>Explanation:</h3>
A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.
