Why do the chromosomes line up in the middle of the cell
Answer:
QUESTION:
Why do the chromosomes line up in the middle of the cell?
ANSWER:
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Explanation:
Hope that this helps you out! :)

Explain why ecologists think the focus of conservation efforts should be ecosystems, not individual species?
It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.
Number the steps from when a stimulus is received to when the body reacts.
_____ The stimulus is received by sensory receptors.
_____ Motor neurons cause muscles to contract so the body can react to the stimulus.
_____ The brain processes the information through interneurons.
_____ Interneurons transfer response information to motor neurons.
_____ Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The correct answer is -
1 - The stimulus is received by sensory receptors.
2 - Sensory neurons carry stimulus information to the brain or spinal cord.
3 - The brain processes the information through interneurons.
4 - Interneurons transfer response information to motor neurons.
5 - Motor neurons cause muscles to contract so the body can react to the stimulus.
Explanation:
In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.
These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.

Which of the following is not a possible benefit of biodiversity?
a
A higher number of species in a food web creates a more stable ecosystem.
b
A greater variety of predators indicates that fewer prey survive within the ecosystem.
c
A greater number of plant species provide more available food for primary consumers.
d
A variety of habitats within an ecosystem supports a greater number of species.
Answer:
b
Explanation:
because the more predators less prey and less organisms
It seems unlikely that biodiversity will result in fewer prey animals surviving in the environment due to the diversity of predators. So, the correct option is B.
What is Biodiversity?The variety of all living things and how they interact with one another and the environment are referred to as biodiversity. Along with species diversity both inside and between them, this also refers to ecosystem and landscape diversity.
Because it helps ecosystems function and provide services like pollination, nutrient cycling, or climate management, biodiversity is significant. For human communities, it also has significant cultural, social, and economic importance.
The range and variety of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the levels of genes, species, and ecosystems is called biodiversity.
Therefore, the correct option is B.
