For the first question, a unicellular eukaryote with autotrophic features (meaning it can produce its own food) will be from either Domain Bacteria and Domain Eukarya, but since Domain Bacteria is not in the choices, then Domain Eukarya is the answer. Domain Archaea are yes, unicellular organisms, but they are not eukaryotes and they do not possess autotrophic features. Domain Eukarya have photosynthetic protozoans (i.e. Diatoms).
For the second question, in Kingdom Fungi, you chose that fungi can either be unicellular or multicellular, which is true, for instance yeast and mushrooms respectively. Fungi are heterotrophic as they cannot produce their own food. The other answer is that fungi are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
For the third question, in Kingdom Protista, you chose that protists can either be unicellular or multicellular, and this is true in the case of amoebas and kelp respectively. Protists can be both heterotrophic and autotrophic. The other answer is that protists are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
In a neuron, axon
is to sending as dendrite is to receiving. In addition regarding neurons, they
transmit messages in the form of electrical impulses and the fundamental
building block of the nervous system. The parts of a neuron are the soma, the
axon, the dendrites and the terminal buttons.
Answer:
Hengityksen hallinta tarkoittaa hellävaraista hengittämistä, vähäisimmällä vaivalla. Se auttaa, kun sinulla on hengähdystauko tai tunnet ahdistusta. Alla olevaa tekniikkaa opetetaan joskus joogassa. Tottuaksesi hengityksen hallintaan, se auttaa harjoittelemaan istuessasi, rentona eikä hengästyneenä.
<u>Answer</u>:
No, speciation doesn’t occur in specific characteristics and predictable manner.
<u>Explanation</u>:
Speciation means creation of a new kind of plant or animal. When a particular species separates from its members of species and develops its own characteristics, speciation occurs.
There are different types of Speciation. In allopatric speciation, species separate due to geographical conditions like waterways or mountain range and evolve into separate species. Whereas in Sympatric speciation, species evolve into separate ones without any change in geographical conditions. Other types of speciation are artificial, peripatric and parapatric type of speciation. So, these changes are neither specific nor predictable.
