Answers

Answer: HERNIATION

Brain HERNIATION represents a displacement of brain tissue under the falx cerebri of through the tentorial notch or incisura of the tentorium cerebelli.

Explanation: Brain herniation is a condition of the brain in which tissues of the brain,blood and cerebrospinal fluid shift from the normal position they are in the skull due to high pressure within the skull as a result of brain tumour,trauma to the brain,stroke or bleeding.

Brain herniation results in cardiac and respiratory arrest,loss of consciousness,high blood pressure and loss of brain stem reflexes example blinking and pupils of the eye reaction to light.

A precipitation reaction is a reaction between two aqueous solutions that results in the formation of a __________ compound.

Answers

A precipitation reaction is a reaction between two aqueous solutions that results in the formation of A SOLID compound.

A precipitation reaction is a type of reaction in which two solutions containing soluble salts react together to produce an insoluble salt (solid) called 'the precipitate'. The precipitate occurs as a result of the combination of the cations and the anions in the solutions. Precipitation reactions are usually used in chemistry to determine the types of ions that are present in solutions.

A precipitation reaction is theformation of a solid compound from the reaction between two aqueoussolutions. The solid compound that is formed is called precipitate. The aqueoussolution that causes the formation of the solid compound is called precipitant.

How are the products of photosynthesis from the leaves get transported to all other parts of the plants​

Answers

Explanation:

These sugars are transported across the plant by the phloem, a mechanism known as translocation. Sinks are sugar distribution points such as roots, young shoots, and developing plants. The product of photosynthesis is transported from source of production to the storage organs through Phloem

Which of the following is a negative effect of algal blooms on the environment?a. transport of carbon to the bottom of the ocean
b. production of oxygen
c. consumption of water’s oxygen
d. large source of energy

Answers

c. consumption of waters' oxygen Although algae produces oxygen during photosynthesis, in an algae bloom the algae is growing at a rapid rate which causes the algae to use more oxygen then it actually produces. When algae is growing rapidly it needs to use oxygen in order to break down glucose into energy through a process called cellular respiration. Cellular respiration requires large amounts of oxygen, so the faster the algae is growing the faster it uses oxygen draining it from the waters the algae lives in and thereby depleting the aquatic environment of oxygen.

Without this one characteristic, the species would become extinct

Answers

There are many species that might go extinct. The one most endangered: White rhinos, with less than 100 in their population. To help these animals, people fund programs like the WildLife foundation. Today, with technology, we haven't had the time to make a change, these people work hard to make sure these animals get proper care and love. :)
