The radiation is coming from an incredibly small object. This source supports the idea that the radiation comes from a black hole.
- The rotating and barycenter of the Milky Way galaxy is known as the Galactic Center (or Galactic Centre).
- Sagittarius A*, a compact radio source that is almost perfectly at the galactic rotational center, is the galaxy's central massive object and is a supermassive black hole with a mass of roughly 4 million solar masses.
- Hawking radiation is a result of how quantum fields behave when there is substantial gravity present.
- Astronomers search for a signal of light from stuff that heats up as it falls into the black hole in order to find this form of radiation, which is only significant for extremely small black holes.
- SgrA is a radio emission source that is situated in the galaxy's nucleus. Within 1 light year away. , several hundred stars are crowded around it.

#SPJ4
The answer would be A true.
Answer:
The correct answer is explained below:
Explanation:
- According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
- It produces the following gametes: TA, Ta, tA, ta.
- The heterozygous tall, terminal plant has the following genotype: Ttaa
- It produces the following gametes: Ta, ta.
- Crossing them,
TA Ta tA ta
Ta TTAa TTaa TtAa Ttaa
(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)
ta TtAa Ttaa ttAa ttaa
(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)
- The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
- The phenotypes obtained are:
- Tall, Axillary = 3.
- Tall, Terminal = 3.
- Short, Axillary = 1.
- Short, Terminal = 1.
The plant used cellular respiration to release energy for use by the cell.
Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).
