What evidence from the study supports the hypothesis that dogs might use a magnetic sense to navigate?
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.

The routes nerve impulses from our senses.
A. thalamus
B. hippocampus
C. brain stem
D. corpus callosum
Answer:
a
Explanation:
The correct answer is C. Brain Stem.
How does the brain stem function?The thalamus and other areas of the brain receive nerve signals from our senses through the brain stem. It is made up of the medulla, pons, and midbrain and is situated at the base of the brain.
The brain stem is in charge of regulating life-sustaining processes including breathing, heart rate, and blood pressure. It is also in charge of transmitting sensory data from the body to the thalamus, which subsequently transmits the data to the relevant parts of the brain.
Although the brain stem is the main pathway for nerve impulses from our senses, the hippocampus, corpus callosum, and thalamus are all important in the processing of sensory information.

The term is almost always used with respect to temperature but is occasionally used for other variables.
Explanation:
What happens to the effenciency of the exchange of oxygen in the human body at a high altitude
Answer:
The effiency decreases at higher altitudes
Explanation:
The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.

Arrange the following concepts from simplest to most complex: Chromosomes, DNA, Genome, Gene
Answer:
DNA -> Gene -> Chromosome -> Genome
Explanation:
A genome is an organism's complete set of DNA including all of its genes. Each genome contains all of the information needed to build and maintain that organism. Chromosomes are the threadlike structures located inside the nucleus of animal and plant cells. A gene is the basic physical and functional unit of heredity.
The material and components that are vital for the growth and functioning of an organism that gets inherited from parent to offspring are the components of genetic information.
From simplest to complex they are arranged as:
DNA ⇒ Gene ⇒ Chromosome ⇒ Genome
DNA is the deoxyribose nucleic acid and is the genetic material that transports the instruction for development and function for growth. Gene is a unit of hereditary that codes for gene products.DNA molecules packed as a thread-like structure is called chromosomes.The entire set of genes that pass from parent to offspring is called the genome.To learn more about genome and genes follow the link:

What soil horizon is the most important for the growth of plants (agriculture) ?
Suggest a way that each farm could change their farming practices to prevent pollution of the river with nitrates. Gizmo
Answer:
An improved agricultural practices such as adjustment of application rate, application of the right amount of nitrogen, use of slow controlled release fertiliser, applying nitrogen fertilisers when least susceptible to loss, crop rotation
Explanation:
The various ways are available to reduce or prevent pollution of the river with nitrates, the most effective is:- reducing or not use of artificial or industrial-based nitrogen fertilizers and using biofertilizers.
Agriculture or farming contributes to water pollution when using fertilizers more than the required amount or easily lost fertilizers. This increases the of nutrients including nitrates in the river that cause the growth of algal bloom and eutrophication.
There are several ways to control the nitrates in the river:
adjustment of using rateapplication of the right amount of nitrogenslow-release fertilizernitrogen fertilizers when least susceptible to losscrop-rotation and use of legumesavoiding over-irrigationThus, the correct answer is: reducing or not using artificial or industrial-based nitrogen fertilizers and using biofertilizers.
