construct a dichotomous key which can be used to identify the five antelopes shown in figure 1.1 use only visible features.
The dichotomous key used to identify the antelopes might be based on the presence/absence of certain muscles, weight, etc.
What is a dichotomous key?A dichotomous key is a system to classify species and/or taxonomic groups by using two different choices.
For example, the presence/absence of certain physical features can be used to identify the antelopes.
Moreover, the threshold in certain features such as weight/height can also be used to classify species.

Geographic isolation caused a population to separate and experience two different environments. With natural selection occurring over many generations, the two populations are no longer able to successfully mate and reproduce. This is what
happens is_____.
O evolution at the species level
O sympatric speciation
O microevolution leading to speciation
O allopatric speciation
Formation of new species or speciation as a result of geographic isolation is an example of allopatric speciation.
What is speciation?Speciation is the process by which new species are formed.
There are several types of speciation;
allopathic speciation sympatric speciation peripratic speciationparapatric speciationAllopatric speciation occurs when species which are isolated from one another by physical barrier, such as a mountain range or a waterway causes new species to form as a result of inability to interbreed.
Therefore, geographic isolation which leads to speciation is an example of allopatric speciation.

Put the following in order from when they occur in the visual transduction pathway:
Optic Nerve receives signal:
Optic radiation receives signal:
Light hits photoreceptors (rods and cones):
Optic chiasm receives signal:
Ganglion cells receive signal:
Optic tract receives signal:
Bipolar cells receive signal:
Primary visual cortex receives signal:
Lateral geniculate nucleus of thalamus receives signal:
The visual pathway consists of the retina, optic nerves, optic Chaism, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex.
The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon.
What is the pathway of vision steps?The visual pathway directs to the anatomical structures responsible for the transformation of light energy into electrical action prospects that can be analysed by the brain.
It begins at the retina and terminates at the primary visual cortex.

Which of the following functions as part of the excretory and respiratory systems?
Answer:
The Lungs.
Explanation:
The lungs are part of the respiratory system as well as organs of excretion. They are responsible for the excretion of gaseous wastes from the body.
The organs of your excretory system help to release wastes from the body. e.g) your lungs are part of the respiratory system. They remove carbon dioxide from your body hence they are also part of the excretory system.N:B- Excretion cleans up after respiration. Respiration is a chemical reaction that takes glucose (sugar) and oxygen to produce energy. But it also produces water and carbon dioxide as bi-products. Excretion gets rid of carbon dioxide, water, and other, possibly harmful, substances from your body.

Would you expect to find older or newer fossils in rock layers closer to the surface? Why?
Answer:
Newer
Explanation:
Because it is like when you place a plant and its roots underground and cover it up. You have the newer dirt going over the newest roots and the roots are close to the top
(If you aren't satisfied with that explanation here's another one) :
A hundred years ago dinosaurs existed and then they died and their remains were buried under dirt. However, we know that the fossils aren't anywhere near the top. Over time fossils get buried under layers of dirt the newer ones will be near the top because they haven't had time to be more buried.
