What is the composition of the asthenosphere?
BartSMP [9]

The asthenosphere lies 80-200km below the surface under the lithosphere. Convection also occurs in the asthenosphere. The asthenosphere is mostly made of up rock material (magnesium and iron silicates). The asthenosphere makes up 6% of the mantle and lets the lithosphere move.

Best of Luck!

Number the steps of the binary fission process in correct order
kari74 [83]

Step 1:

The bacterium cell must copy its DNA so the new cells will have DNA. DNA or, deoxyribonucleic acid, has all of the information the bacterium will need to survive, so it is important it gets copied. The DNA is tightly wound so it is in a neat package called a chromosome.

Steps 2 and 3:

The bacterium now grows larger. This allows for some separation between the two DNA copies that are inside the cell. A division develops in the middle of the bacterium. This division eventually completely divides the bacterium in half. This is called cytokinesis.

Step 4:

Each cell is now called a daughter cell and they separate.

The steps of binary fission

binary fission

Binary fission results in two identical daughter cells. This is a type of asexual reproduction, or creating genetically identical offspring. If humans were able to reproduce using binary fission, it would look something like this: your mother or father would grow larger, and inside all of his or her DNA would be copied. Eventually your parent would split in half creating an identical clone.

Which of the following phenotypic classes reflect offspring that were generated as a result of a recombination event?
babymother [125]

Answer:

The correct options are: A " vestigial wings, red eyes" and D "full wings, purple eyes"

Explanation:

female parent: vg+pr+/vg pr

(phenotype - full winged and red eyes)

male parent:  vgpr/vgpr

(phenotype - vestigial winged and purple eyes)

Of these traits, vestigial wings and purple eyes are recessive traits. Hence, when a recombination event occurs, the offspring can potentially have a wild type trait paired with a recessive trait.

The ______ system is assisted by the lymphatic system and the physical barriers of the skin and gastrointestinal tract.
mezya [45]

Answer:

The correct answer is- Immune system

Explanation:

There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.

The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.

Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.  

So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
