Please help me with this biology question...........
Chloroplasts are present in some plant cells only Give an example of plant cells that do not contain chloroplasts and explain why
Answer:
Chloroplast is specific to plant cell because plants are the autotrophs which can prepare their food by conversion of light energy to chemical energy. It is the vital photosynthetic pigment in leaves as it involves the conversion of light energy into chemical energy.

Please Helppp!!! What could lead to different populations of the same species living in different environments?
Answer: Migration, because species move to other places for food or a better or more suitable habitat and sometimes their is other species there.
Different ecological and biogeographical causes lead to different populations of the same species living in different environments. Ecological factors include intraspecific competition, migration, resource searching, habitat destruction, among others. Biogeographical dispersion involves wider areas and time factor. Human action is also a cause of dispersion.
-----------------------------------
Dispersion can be defined as the dissemination and distancing process of some individuals from others. It refers to the change in an organism's range or distribution area.
Different ecological and biogeographical processes might be involved in organisms' dispersion.
Ecological processes involve intraspecific competition for resources, habitat destruction, lack of resources -food or water-, among others. This is an intra-area, moderate dispersion that reduces competition and increases niche findings. It involves daily and seasonal migration and territoriality. Biogeographical processes refer to bigger changes that involve wider areas and time. It includes the historical factor, besides migration. This is an extra-area dispersion process.→ Jumping dispersion refers to a few individuals, in a short time, that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. They must reproduce and start a new population of a certain size that can survive the new conditions.
→ Diffusion refers to populations that, through many generations, explores and expands in new regions with favorable conditions.
→ Secular migration is the diffusion through thousands of generations.
Dispersion is also caused by human actions, following different interests and goals.When two populations of the same species migrate to new areas and adapt to different environmental pressures, they will probably suffer from the speciation process with time, becoming two different species.

It is D
this shows that there was likely greater diversity during the time that is represented by that rock layer
it could also be random chance that those fossils ended up being fossilized in that location as fossilization is a random and rare occurence so this is usually corraborated with multiple locations
also remember that a mass extinction event can fit within as large of a window as over 100k years because dating isn't bang on and a large cataclysmic even could take a long time for it to effect the whole planet enough to cause a mass extinction
Explanation:
It is D
Because it shows that there was a greater diversity during the time that is represented by that rock layer , it could also be random chance that those fossils ended up being fossilized in that location as fossilization is a random and rare occurence so this is usually corraborated with multiple locations

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

Anatomy
Label each of the following structures or processes.
Answer:
A - DNA
B - mRNA
C - nuclear pore
D - tRNA
E - ribosome
F - rRNA
Explanation:
The entire structure illustrates the process of transcription and translation in a typical eukaryotic cell.
The DNA (A) in the nucleus of the cell is first transcribed to mRNA (B). The mRNA produced is transported to the cytoplasm through the openings within the nuclear membrane - the nuclear pores (C). On getting to the cytoplasm, the mRNA binds to the ribosome (E) (carrying rRNA, F). The tRNA (D) carrying the specific anticodon for a particular codon on the mRNA then binds to the structure and the corresponding amino acid is released. A polypeptide bond is formed between subsequent amino acids and the ribosome moves along the mRNA chain until the translation process is complete.
