A gymnosperm will have everything BUT flowers, Gymnosperms are tree like so they have woody growth, they produce seeds with pollen, they have leaves like most vascular plants, and since they are vascular they have vascular tissue, they have all of that except a fruit protecting the outside of the seed.
Hope this helps, if not, comment below please!!!!
B) their DNA sequences
C) their physical characteristics
D) their behavioral characteritics
The correct answer is option B) their DNA sequences.
The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
The correct answer is option C which is globular. And the correct statement is:
Globular star cluster forms from tightly packed groups of older stars.
The type of star cluster that forms from tightly packed group of older stars is called “The Globular cluster.”
Globular cluster is known to contain large group of old stars that are tightly and closely packed accordingly in a symmetrical but spherical form.
Globular clusters are the largest and most enormous star clusters, and are known to usually appear in roughly spherical forms.
Globular clusters are usually formed through molecules of giant cloud, or enormous masses of gas that form stars due to their collapse. Notably, globular clusters cannot form today as a result of the current limited availability of free gas compared to its abundance at the early stage of the universe.
Globular clusters are found to be the oldest objects existing in the Galaxy. Globular clusters are said to contain between hundreds of thousands and millions of stars, and are heavily distinguished among other clusters due to their old age uniformity.
The relative ages of elements in globular clusters ranges from 11 billion to 13 billion years after being determined by comparing stellar population of globular clusters with stellar evolutionary models.
It should be noted that they could be as young as 9 billion years old based on modern developed research models.

The Correct answer is option D
When a person is sick then it means that its immune system is already weak and the white blood cells of sick people do not work efficiently.
In this case if the body is administered with vaccination then there are chances that the person might die or become adversely sick.
Vaccination is given to evoke immune response by the help of White blood cells and if it is already not working efficiently then the vaccine can make the make person more ill.
