Answer:

Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, the blood thickens and clumps to form a blood clot in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.

Answer:

The cell was first discovered by Robert Hooke in 1665 using a microscope.

The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.

Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery.

Answer:

1. Zacharias Janssen invented the microscope, while the first to describe cells was Robert Hooke

2. Robert Hooke was the first scientist to do so

Answer:

It would mimic the behavior of the earth's atmospheric atmosphere where you have a water cycle and sunlight which aids photosynthesis.

Explanation:

A terrarium is a glass container that can be covered and opened at will. It can be used to grow a plants using soil.

When it is sealed, water evaporates onto the body of the glass and runs down the sides of the glass only to be evaporated again and the same process happens over and over again.

Because the plants are in a glass container, they can still access sunlight for photosynthesis.

Sometimes the glass is opened up for maintenance. Maintenance here refers to the removal of algae that sometimes forms on the inner walls of the terrarium. Sometimes, there is also need to add water to the ecosystem in the terrarium given that the water inside usually escapes via evaporation over time.

Explanation:

Answer:

The correct answer is ''pharyngeal slits (or clefts) of invertebrate chordates.''

Explanation:

The neural crest is a temporary structure that develops as the neural tube closes. Its migratory capacity and subsequent distribution during development is a basic point in the general embryonic development and of most organs and structures in particular.These cells contribute to the formation of head cartilage and tooth dentin in fish embryos; and a large number of tissues and structures are formed from the migration of neural crest cells. Invertebrate chordates are animals of the Chordata phylum that have a notochord at some point in their development, but do not have a backbone. With a hollow nerve cord, neural tube. It appears by invagination of the dorsal surface; the tube is formed with a central cavity lined by ependyma; the anterior part of the neural tube gives rise to the brain. The neurenteric canal is a communication channel between the neural tube cavity and the intestine. The pharyngeal clefts (pharyngotremia), originally used for food; It is a filtering device that retains food particles that are included in mucus and transported to the intestine. In fish it already acquires respiratory function. In the ventral part, a groove is formed with cilia and bands of glands: endostyle or hypobranchial groove.

Answer: 1. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. 2. But scientists were at a loss to explain why some pieces of crust move much faster than others. A new study suggests these tectonic plates control their own speed more than the mantle does. ... The velocities of these plates and the velocities of the boundaries between these plates vary significantly on Earth." 3. Divergent boundaries -- where new crust is generated as the plates pull away from each other.

Convergent boundaries -- where crust is destroyed as one plate dives under another.

Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Explanation:

Answer:

✦ The birth and death rates will balance each other out for a net growth rate of zero.

✦ Death rate will increase, and birth rate will decrease until they balance each other out.

✦ The population will no longer grow in size.

Explanation:

Due to practical limitations of food, water, and space, a given environment has a maximum population size it can support.

Answer: Understand about transformation as part of this. ... Is protein the transforming factor? protein-destroying enzymes---made the strains grow so concluded that protein doesn't transform because the bacterial colonies were still transformed. He concluded that protein could not be the transforming factor.

Answer:

Igneous rocks

Explanation:

Igneous rocks that form below the Earth's surface are called intrusive igneous rocks (or plutonic). They form when magma enters an underground chamber, cools very slowly, and forms rocks full of large crystals. Igneous rocks that form above the Earth's surface are called extrusive igneous rocks.

Answer: Its wider and thicker than most blood vessels

Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.

Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.

Answer:

Nervous system messages travel through neurons as electrical signals.

Explanation:

When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.

The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.

It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.

From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.

Thus, the answer is 550 million years ago.

The statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.

Evolution may be defined as the change in the characteristics of a species over several generations and relies on the process of natural selection.

Wisdom teeth are evolved in humans because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose.

Therefore, the statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.
