They are different in structure as one serves in an open system (lymphatic system) while the other serves is closed system (circulatory system).
Hope this helps!
*This question is common, so this answer I use a lot. I copied my own work.*
Answer: Clearly his SYMPATHETIC nervous system has been activated.
Explanation:
The effects of the sympathetic nervous system dominate in times of EMERGENCY or STRESS. And its effects include:
- dilation of pupils to help Gabe see sharply as he investigate
- inhibition of saliva secretion as his mouth turns dry
- acceleration of heartbeat due to fear
- stimulation of sweat glands to produce sweat.
All these show clearly that Gabe's SYMPATHETIC nervous system has been activated.
The answer would be d because the genes come the two parents
<h2>b) is the correct option </h2>
Explanation:
The biological species concept defines a species as a group of individuals living in one or more populations that can potentially interbreed to produce healthy, fertile offspring
- The biological species concept connects the idea of a species to the process of evolution
- Because members of a species can interbreed, the species as a whole has a common gene pool, a collection of gene variants
- In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed
- In some other cases, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce
Hence it includes the groups which are reproductively isolated so asexual fungi will be least relevant to this group
As you can see in the table presented below, all of the gametophytes have seeds do not form in an enclosed structure and <span>undergo alternation of generations (marked in purple)
The gingkos were widespread in the distant past, but are now presented with only one species with fan-like leaves, the Gingko Biloba. (green)
The gnetophytes have three genera with very different looking species. One of the most iconic ones being the Welwitschia mirabilis often called the wise man's beard. (blue)
The conifers include redwoods, like sequoias and all, have pines as leaves and produce cones. (brown)</span>
