Answer:

FMRI helps to measure and map the brains activities.

Explanation:

FMRI refers to Functional Magnetic Resonance Imaging. It helps to measure and map the brain's activity.

FMRI scan works by looking at the blood flow in the brain to detect areas of activity. Glucose is the main source of energy in the brain,but not stored in the brain. So when parts of the brain need energy o perform action, more blood flow in to transport more glucose.

FMRI scan helps doctors to map out the brain before surgery and provides more information about individual brain to prevent serious injury before the surgery.

It also helps doctors monitor a progressive condition like dementia to study how the disease progresses.

glucose levels go up in the bloodstream after a meal. beta cells of the pancreas detect the elevated glucose levels. this causes
Keith_Richards [23]

The secretion of insulin into the bloodstream is done through exocytosis and absorption through the capillary arteries.

Insulin is a protein required to process sugar. This is a <u>naturally produced protein</u> for which the pancreas is responsible. The insulin Protein is considered a transport protein. It is responsible for carrying glucose from the bloodstream into cells to be used as energy.

This protein is of vital importance. The secretion of this protein is done through exocytosis, which means that after passing through the ribosomes and the Golgi, it is contained within a membrane, which will then fuse into the plasmatic membrane and be released from the cell. It is then absorbed through the capillaries to enter the bloodstream.

Explain how the substitution affect in the income effect interact with changes in price to change the quantity demanded
kolbaska11 [484]

Answer:

For normal goods, the income effect and the substitution effect both work in the same direction; a decrease in the relative price of the good will increase quantity demanded both because the good is now cheaper than substitute goods, and because the lower price means that consumers have a greater total purchasing power.

Describe the control group for an experiment that examines the effect of fire intensity on the biodiversity of tree communities.
Vladimir79 [104]

Answer:

explanation below

Explanation:

The control group would be the biodiversity of the trees without the fire

The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.

1.) Librarians organize books according to a classification system. Describe another type of classification system you have seen
marysya [2.9K]

Answer and explanation:

<h3>1. Librarians organize books according to a classification system. Describe another type of classification system you have seen or used.</h3>

<u>Similar to the way librarians organize their books, taxonomists and biologists can classify living organisms</u>.

In terms of biology, the taxonomic categories of species is a system used to group different species according to their physical and functional characteristics and their phylogenetic relationship.

Taxonomy can classify living organisms into domains - according to their cellular characteristics, as well as placing them in Kingdom, Phylum, Class, Order, Family, Genus and Species.

For example, man (Homo sapiens) is classified, according to his taxonomy in:

  • <em>Domain: Eukarya. </em>
  • <em>Phylum: Chordata. </em>
  • <em>Class: Mammal. </em>
  • <em>Order: Primates. </em>
  • <em>Family: Hominids </em>
  • <em>Gender: Homo </em>
  • <em>Species: Homo sapiens. </em>

The taxonomic classification system is a way of establishing differences and similarities among living beings, as well as offering an approximation to their morphology and specific functions within nature.

<h3>2. Describe three examples of how are plants and animals different</h3>

Plants belong to the Plantae kingdom, while animals belong to the Animalia kingdom, and there are clear differences between them:

  1. <em>Plants have no movement, while animals do. </em>
  2. <em>Plant organisms are capable of processing their own nutrients (autotrophs), through sunlight, carbon dioxide, oxygen, water and inorganic nutrients from the soil. Animals (heterotrophic) require to obtain their nutrients by consuming plants or other animals. </em>
  3. <em>In plants, plant cells have cloproplasts and chlorophyll, which are necessary for photosynthesis and to obtain energy substrate. The animal cell has mitochondria, which are in charge of cellular respiration, a process that provides them with energy. </em>
<h3>3. Describe three examples of how are plants and animals are similar</h3>

The similarities between plants and animals are based on the general characteristics of some living organisms:

  1. <em>They are eukaryotic multicellular organisms, formed by biomolecules such as carbohydrates, lipids and proteins. </em>
  2. <em>They have the capacity to reproduce and respond to stimuli. </em>
  3. <em>The metabolic pathways to carry out their organic processes - such as obtaining energy - are similar.</em>
<h3>4. What are some differences between plants and fungi? What specific characteristics that you observed from this activity might help you classify this organism?</h3>

Some differences between plants and mushrooms are:

  1. <em>Plants are photosynthetic organisms, capable of processing their own nutrients. Fungi require feeding on organic matter (heterotrophic). </em>
  2. <em>The nutrition of plants is by absorption of inorganic nutrients from the soil, while fungi perform an external digestion process and then make the absorption. </em>
  3. <em>From the cellular point of view, the wall of the plant cells is predominantly cellulose, while in the fungi the main component of the cell wall is chitin. </em>

An observable characteristic that allows us to establish the difference between plants and fungi is that plants are generally green, due to the presence of chlorophyll, necessary to carry out photosynthesis, while fungi are of variable colors, such as white, yellow, reddish or brown (they lack chlorophyll).

Because andy has high blood pressure and heart disease, he must lower his intake of
klemol [59]

Answer;

-Sodium

Because Andy has high blood pressure and heart disease, he must lower his intake of Sodium.

Explanation;

-Eating substances rich in sodium such as salt raises the amount of sodium in the bloodstream and wrecks the delicate balance, reducing the ability of the kidneys to remove the water.The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.

-Therefore, for an individual with high blood pressure and heart disease like the case of Andy, he or she must lower the intake of sodium.
