Answer:
poliinators and flagellated sperm
Explanation:
Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.
Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.
Also, unlike other groups of gymnosperms, cycads have specialized pollinators, beetls.
It’s the control group.
The reason why is because the experimental group is the group in which they are experimenting with while the control group isn’t receiving any experimentation
The hindbrain consists of the medulla, the pons, and the cerebellum.
<h3>The hindbrain</h3>
The hindbrain is the portion of the brain that is otherwise known as the rhombencephalon. It is the part of the brain that is located towards the lower back.
The hindbrain consists of 3 main parts:
- The medulla oblongata
- The pons
- The cerebellum
Each component has specific functions they perform. The medulla oblongata is located at the extreme end where the brain connects with the spinal cord. It controls activities such as heartbeat, blood pressure, and respiration.
The pons of the hindbrain work hand in hand with the medullar oblongata for effective breathing. In addition, it is the part of the brain that controls the circadian rhythm of the body.
The cerebellum helps the body to maintain postural balance and adjustments when necessary.

#SPJ1
Answer:
Biological: 2) not applicable for extinct species.
Morphological: 3) relies on similarities of structures. The morphology studies the structures.
Phylogenetic: based in the history of the specie
Morphological and phylogenetic : 1) acommodates asexual reproduction and 5) species acceptance criteria can be subjetive
all three: 4) used by scientists in classification
Answer:
D.) Gene Flow
Explanation: In a population genetics, gene flow (also known as gene migration or allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population.
