Explanation:
hope this helps. ♥️
Parasitism is the type of symbiosis that occurs between a deer and the tick. So, the correct option is C. This is because bacteria infect their host cell which is found in Deer.
What do you mean by Symbiosis?Symbiosis may be defined as a relative ecological association between the individuals of two or more different species.
The type of symbiotic relationship found between oxpecker and zebra is Mutualism. This is because oxpecker is able to get its prey (food), while zebra is benefitted from the removal of insects from their body. So, the correct option is A.
The type of symbiotic relationship between Humans and bacteria living in their digestive tract is Mutualism. This is because Humans are benefitted from bacteria as they assist in digesting food, while bacteria also benefit to find a proper place where unlimited food is available. So, the correct option is A.
The type of symbiotic relationship between Barnacles and whales is Commensalism. This is because Barnacles are benefitted from excess food and easy transportation, while whales are neither benefitted nor harmed by this relationship. So, the correct option is B.
Therefore, each of the questions are properly described above.

dna is synthesized through a process known as _____.
Dna is synthesized through a process known as DNA Replication.
DNA is synthesized through a process known as - DNA replication or semiconservative replication.
DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA
Step 2since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.
Step 3
the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one
Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.

the spinal cord achieves the function of locomotion through __________.
Answer:
groups of neurons called central pattern generators
The spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.
What are the groups of neurons in the spinal cord?Even when cut off from the brain and sensory inputs, "central pattern generators" (CPGs) nerve networks in the spinal cord can generate rhythmic motions like swimming, walking, and hopping.
In the absence of sensory or descending inputs that contain precise timing information, central pattern generators are neural networks that, when triggered, may create rhythmic motor patterns like as walking, breathing, flying, and swimming.
The spinal cord facilitates the movement of bodily components, accidents frequently result in people being unable to utilize certain body parts like the legs.
Therefore, the spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.

Which of the following statements defines ovulation?
Ovulation is when an immature ovum develops into a mature ovum.
*Ovulation is the release of a mature ovum, which occurs once each month.
Ovulation is the production of an ovum that occurs each month.

b. Ovulation is the release of a mature ovum, which occurs once each month.
Explanation:is correct. post protected
Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.
What is ovulation?The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.
Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.
Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.
Thus, the correct option is B.

which specialized structures are unique to the cnidarians?
Explanation:
Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers).
Cnidarians have stinging cells which are known as cnidocytes. This is the unique feature of cnidarians.
What are cnidarians and their characteristics?The class Soft-bodied stinging creatures like corals, sea anemones, and jellyfish are categorized as Cnidaria. Nearly every ocean ecosystem contains cnidarians. They may survive in warm or cold, shallow or deep water. Freshwater is home to a few species. Cnidarians can either live alone or in colonies.
Cnidarians share a number of fundamental traits. Cnidaria is all aquatic organisms, primarily marine ones. All of them have stinging tentacles called nematocysts that they utilize to capture prey. Cnidarians have just two body layers: the ectoderm and endoderm, which are divided by a layer that resembles jelly and is known as the mesoglea.
Thus, cnidocytes are unique features of cnidarians.
