Answer:

Earth's surface didn't look much different. With few exceptions.

The global climate is cooler and drier, and seasonal, similar to modern climates. As the climate began to cool down grasslands continued to expand and forests started to dwindle in extent. In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.

Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.

In the following image, what conclusion can you draw about the speed of the planet at location A compared to location B? (2 poin
aleksandr82 [10.1K]

The answer is; When the planet is at A it is moving faster than at B.

This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.

Anthony returns home from work. When he opens the front door of his house, he detects a strong smell of gas. He suspects that hi
Natali5045456 [20]

Given what we know, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.

<h3>What is sensation?</h3>

The sensation is a process that activates for each of the 5 senses. In this process, sensory neurons receive a stimulus and activate, sending a neural impulse to the brain with the information gathered. This information resulted in the ability to identify the smell as gas.

Therefore, we can confirm that Anthony is able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.

Loss of fluid from the plasma will in part be replaced by fluid moving ______ cells. group of answer choices
8_murik_8 [283]

Loss of fluid from the plasma will in part be replaced by fluid-moving hypertonic cells.

What is a Hypertonic solution?

Hypertonic has a larger proportion of fluid, carbs, and salt than blood.

Blood and isotonic have similar fluid, sugar, and salt contents.

If there is a higher concentration of solutes outside the cell than inside it, as would happen if you put red blood cells in a concentrated salt solution, the salt solution is hypertonic in relation to the interior of the cells.

A fluid that contains more dissolved particles than blood or normal cells, such as salt and other electrolytes. The relative osmolarities between solutions are denoted by that of the term hyperosmotic, hypoosmotic, and isoosmotic.

For instance, when comparing two solutions with differing osmolarities, the higher osmolarity solution is referred to as hyperosmotic, and the lower osmolarity solution is hypoosmotic. Isoosmotic solutions are those that have the same osmolarity.

Hence, the correct answer is Hypertonic.

Brrunno [24]

Answer:

A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...

Explanation:

Involved in the transport of proteins with the first signal sequence but not the second one.
