___________ are multi-function glial cells that participate in phagocytosis, provide lactate for cells, and structurally support neurons in the brain. Schwann Astrocytes Microglia Oligodendrocytes Microtubules
Astrocytes are the multi-function glial cells that participate in phagocytosis, provide lactate for cells, and structurally support neurons in the brain.
What are Glial cells?Glial cells may be defined as the neurons of the central nervous system which are supplied by several varieties of non-excitable cells.
Astrocytes serve as phagocytes by taking up degenerating synaptic axon terminals following the death of the neurons due to diseases. They represent the process of replacement gliosis.

PLEASE HELPPPPPPP MEEEEEEEEEEE
Answer:
C and D
Explanation:
The nucleus (the dark blob in the center of the cell) is clearly visible in every cell in the diagram, which means that this is a eukaryotic cell undergoing mitosis. F is, therefore, not a correct answer. The product of mitosis is two genetically identical daughter cells.
Binary fission occurs prokaryotic cells, and does not apply in this case, so A is not a correct answer.
Cells do not undergo $exual reproduction, so B is not a correct answer.
While eukaryotic cells generally do have ribosomes, it is possible to infer that the cells contain ribosomes. However, the ribosomes are not visible in the diagram, so E is not a correct answer.

On DNA, a ____________________ base will always pair with a __________________ base.
Answer:
Purine, Pyrimidine
Explanation:
DNA bases consist of two subgroups,
Purines: Adenine and Guanine
And Pyrimidines: Cytosine and Thymine
In genetic material, Adenine bases are always paired with Thymine bases, and Guanine bases are always paired with Cytosine bases. This is why a Purine base will always be paried with a Pyrimidine base.
Fun tip: If you have a hard time remebering which bases are which, a trick I personally use is that Alanine and Guanine are purines, and their code letters (AG) are the symbol for the element silver, which is a type of pure alloy. So AG --> Silver --> Pure --> Purine

Transformation is the transfer of dna from a donor to a recipient cell:
Transformation is the transfer of DNA from a donor to a recipient cell, mediated by a bacteriophage through the process of crossing over.
What do you mean by DNA?DNA stands for Deoxyriobo nucleic acid. It is considered the genetic material in most of the organisms living on the earth's surface.
It is the process that involves the horizontal gene transfer among prokaryotes. During this process, the DNA of the donor cell integrates into the recipient cell.
Therefore, transformation is the transfer of DNA from a donor to a recipient cell, mediated by a bacteriophage through the process of crossing over.

You set out to observe the symbiotic relationship between a species of orchid and a species of fly. This species of orchid is only pollinated by this one species of fly, and the flies seem to prefer that orchid over any other flower for its nectar supply. Identify and describe two reasons for the proximate causation for the species-specific preference of this fly. Select one of the reasons and make a prediction on the outcome on species-specific preference of the fly. Justify your prediction with evidence
The two reasons for the proximate causation for the species-specific preference of this fly include:
NectarColorWhat is Symbiosis?This is described as the interaction between two dissimilar organisms which in this case is between the orchid and fly.
The color of the orchid is bright which attracts the fly to it thereby resulting in pollination. This is because they come in contact with the anther which contains the pollen grains.

A mountain range that separates two
species of bears is an example of which
of the following types of barriers?
A. ecologic isolation
B. temporal isolation
C. geographic isolation
D. mechanical isolation
A mountain range that separates two species of bears is an example of geographic isolation. Thus, the correct option for this question is C.
What is Species separation?Species separation may be characterized as a type of mechanism through which species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
The process of speciation may occur due to isolating mechanisms, like geographical isolation which is known as allopatric isolation. Different geographical areas play an important role in the process of separating two or more species that give rise to speciation.
Therefore, a mountain range that separates two species of bears is an example of geographic isolation. Thus, the correct option for this question is C.
