Answer:
For each fish's skin surface, a row of unique cells is contained inside a particular canal that runs the length of its body. This is referred to as the "lateral line," because it enables them to sense vibrations in the water. Fish are able to notice activity around them as well as changes in the flow of water thanks to their sixth sense.

Explanation:
a cockroach is a fast-moving insect. how can an animal with an open circulatory system be so speedy?
Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something
An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.
What is an Open circulatory system?An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.
Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.
Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

distinguish between uric acid, urea and ammonia
Answer:
Explanation:
Ammonia is associated with aquatic animals; urea is associated with most terrestrial and semiterrestrial vertebrates, but rarely land invertebrates (Campbell et al., 1972); and uric acid is the major product of terrestrial invertebrates, birds and reptiles (Prosser & Brown, 1961).
Describe how the Earth’s surface changed over time?
Answer:
Earth's surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth's surface much more quickly.There are basically 2 types of changes that occur to the earth's surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process.
Explanation:
Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. When it comes to changes on the Earth's surface, the main processes to take into account are plate tectonics and the rock cycle as well as the sea-floor spreading. ... These collisions causes mountains and volcanoes to form on the plate boundaries and thus changes the shape and form of the landmass

What is the role of chromosomes in the cell nucleus?
Explain in 5 - 10 sentences
Answer:
Chromosomes are tightly packed DNA and proteins. The DNA and proteins take on a tightly coiled structure within the chromosome. The chromosomes are then kept inside the nucleus. Their role is to carry basic genetic material. This provides the cell with genetic information that's used to carry out different cellular functions. These functions include survival, growth, and the ability to reproduce.

!!PLEASE ANSWER CORRECTLY!!
Answer:
The structure that is responsible for the governance of a cell is the DNA, which is located in the nucleus of the cell.
Explanation:
DNA: It is the genetic material containing genetic information.It is present in the chromosomes inside the nucleus. The genetic information of DNA is stored as code in the four nucleobases namely Adenine, Guanine, Cytosine, and Thymine. The most unique feature of the DNA is that it is self-replicated and makes similar copies of itself. DNA is a double helical structure found in all living organisms including some viruses.In Eukaryotes along with the nucleus, DNA is also present in Mitochondria and Chloroplasts.For more information:

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.
Answer: T1-T11; two adjacent ribs
Explanation:
The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.
What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.Learn more about rami of spinal nerves here:

Which of the following characteristics do homologous chromosomes exhibit?.
Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.
Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.
Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.
