Answer:
D) Both lack membrane-bound organelles and are single-celled.
Explanation:
The answer is D because the main difference between Archaea and Eubacteria is they differ in the formation of their cell wall. Archaea's cell walls are made of uncommon lipids while Eubacteria have cell walls made of peptidoglycan.
Natural selection is the process by which an organism uses its traits to survive and reproduce. In this mechanism of evolution, organisms have favorable traits for survival and reproduction. The more adapted an organism is to its environment, the more likely it is to have heritable traits that are passed down to new coming offsprings, and really, this also applies for the likeliness of the organism to survive and reproduce in general. The more these heritable traits are passed down and used with offspring, the more common the favorable traits are in the community.
Answer:

Explanation:
An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.
On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.
Let's look at the answer choices.
A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.
However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be <u>abiotic.</u>
Lesions to the medial geniculate of the amygdala block conventional auditory fear conditioning.
Medial geniculate
The medial geniculate body (MGB) is a collection of nuclei that receives heavy input from the IC and acts as a key synaptic junction on the routes that carry data to the cerebral cortex's auditory regions.
One should also think about how the medial geniculate's structure might affect its possible roles as a relay nucleus given the substantial studies on its anatomy. It is not in question that the MGv, which is the lemniscal portion of the MGB, "relays" accurate auditory information to the primary auditory cortex.
