Answer:
Hox genes regulate sex determination in mammals.
-Hox genes regulate flower development.
-Hox genes encode transcription factors that respond to steroids.
-Hox genes encode transcription factors with a DNA-binding domain called a homeo box and regulate development of the vertebrate body plan
- Hox genes are transcription factors that bind to specific DNA sequels called homeodomains
and regulate development of the vertebrate body plan.
Hox genes are transcription factors that bind to specific DNA sequences called
homeodomains.
Explanation:
The right answer is B. The tree absorbing carbon dioxide
The Earth's atmosphere is the gas / particles surrounding our planet. Most of the air consists of nitrogen, oxygen, then other gases, including argon and carbon dioxide.
Biosphere is a planetary system including all living organisms and environments in which they live (the tree in this exercise).
Answer:
<em>D) lining up of chromosomes in the cell</em>
Explanation:
Prophase can be described as the first stage of cell division. During this phase, The chromatin material condenses and becomes compact so that the chromosomes become visible. The nuclear envelope disintegrates and the nucleolus disappears. Hence, the choices mentioned in option A, B and C occur by the end of prophase.
Metaphase is the third phase of cell division. During this phase, the chromosomes line themselves in the centre of the cell. Hence, the lining of the chromosome does not occur by the end of prophase. This occurs during the third stage.

6. Unsure but I think D. the one below the apex predator's prey
7. A. True
8. B. False
9. Unsure but I think C. the crab moves to less salty water
10. D. Among different species
Explanation:
Scientific reasoning requires following the scientific method.
1. You foremost make an observation about the universe.
2. Make a hypothesis as to why that phenomenon is the way it is.
3. Design an experiment to test your hypothesis. Hypotheses can be thought of as "predictions"
4. Finally draw a conclusion based on the results of your experiment. Was your hypothesis proven to be valid?
