Answer:

Tracer

Explanation:

Tracer arrow can be defined as an arrow that is used to show the movement of data from one cell the other.

It provides visual evidence of the relationship between an active cell and other related cells. This means that it provides a visual clue to the relationship between two cells by pointing from the precedent cell to the dependent cell.

Tracer arrows provides information or data about two cells.

a. Precedent cells: Precedent cells are cell that always have a formula contained in them.

b. Dependent cells: Dependent cells are cells that always have a constant value.

Answer:

Explanation:

habitat

Habitat Grasslands  Common Nighthawks nest in both rural and urban habitats including coastal sand dunes and beaches, logged forest, recently burned forest, woodland clearings, prairies, plains, sagebrush, grasslands, open forests, and rock outcrops. They also nest on flat gravel rooftops, though less often as gravel roofs are being replaced by smooth, rubberized roofs that provide an unsuitable surface. During migration, Common Nighthawks stop in farmlands, river valleys, marshes, coastal dunes, and open woodlands. Their South American wintering habitat is not well known.

Food

Food Insects Common Nighthawks eat flying insects almost exclusively. The Common Nighthawk hunts on the wing at dawn and dusk, opening its tiny beak to reveal a cavernous mouth well suited for snapping up flying insects. It often takes advantage of clouds of insects attracted to streetlamps, stadium lights, and other bright lights. Nighthawks eat queen ants, wasps, beetles, caddisflies, moths, bugs, mayflies, flies, crickets, grasshoppers, and other insects. They may also eat a small amount of vegetation. Though they forage in low light, they seem to locate prey by sight, possibly with the help of a structure in their eyes that reflects light back to the retina to improve their night vision. They occasionally forage during the day in stormy weather, but seem to never forage at night. Common Nighthawks may forage near the ground or water, or more than 500 feet into the sky.

At which stage would centromeres of sister chromatids Disjoin and chromatids separate?
Debora [2.8K]

Answer:

Anaphase II.

Explanation:

Cell division may be defied as the phenomena by which the cell multiply and increases its number under the influence of cell cycle checkpoints. Two main type of cell division are meiosis and mitosis.

The meiosis result in the formation of four haploid cells from the single parent diploid cell. The Anaphase II of meiosis leads to the disjoin of the sister chromatids and the separation of chromatids. This is similar to the anaphase of mitosis.

Thus, the correct answer is anaphase II.

Which hormone does the sympathetic nervous system release to increase heart rate.
sertanlavr [38]

The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.

<h3>What is a heart rate? </h3>

it is the number of contractions of the heart per minute.

<h3>What are catecholamines?</h3>

These are the neurotransmitters that have a catechol and a side chain that is an amine.

<h3>Which catecholamines are released by the sympathetic nervous system?</h3>

Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.

<h3>Where are these hormones released?</h3>

These hormones are released in the blood.

<h3>How does this hormone increase the heart rate?</h3>
  • "These hormones are released at the neuromuscular junction of the cardiac nerves."
  • "They shorten the repolarization period."
  • This speeds up the rate of depolarization and contraction and thus the heart rate is increased.

Use the drop-down menus to identify the types of convergent boundaries labeled A, B, And C.
algol [13]
Oceanic-continental convergence occurs when an oceanic plate and a continental plate converge. They are pushed together and the oceanic plate is forced to go under the continental plate. So based on the diagram, this convergence occurred in letter B. 

Oceanic-oceanic convergence occurs when two oceanic plates collide into one another. The oceanic plate that is older, denser and/or colder will be the plate that will go under the other. It will be forced down into the mantle. So in our diagram, this occurs in letter A.

Continental-continental convergence occurs when two continental plates converge. In this case, the plates push up against each other and create mountain ranges. Unlike the other two, they do not sink down, the movement is upwards. This occurs in the area C of your diagram.
