Answer:

The speed at which the reactants change to products over a given time.

Explanation:

A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.

Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:

reactants → products

Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>

According to the temperature and other parameters, the reaction rate can increase or decrease.

The body loses water in a variety of ways. Put the water output mechanisms in order from greatest contribution to fluid loss (1)
kirza4 [7]

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces

<h3>What are the ways in which body loses water ?</h3>

Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.

The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.

Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.

Illusion [34]

A body of underground water, usually comprised of water saturated regolith, is permeable, and replenishes lakes and streams, is known as a aquifer.

Groundwater to be able to get into a rock with good porosity it must also have good permeability. For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.

An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers confined and unconfined.

What is the cause of the hydranencephaly? Select one: a. Aqueductal stenosis b. Subaranchoid stenosis c. Overproduction of CSF d
Dennis_Churaev [7]

Answer:

The correct answer is d.

Explanation:

Hydranencephaly is a rare congenital anomaly characterized by the absence and replacement of the cerebral hemispheres by cerebrospinal fluid and necrotic remains, with preservation of the membranes (leptomeninges), within a skull of normal capacity and shape. It is the most severe form of cortical destruction cerebral bilateral and is considered an extreme form of porencephaly (focal cystic cavity). It mainly affects the territory of the internal carotid artery and middle cerebral artery, with preservation of the territories supplied by the vertebrobasilar arteries. The most accepted etiology is carotid vascular insufficiency, due to multiple causes (bleeding, placental thromboembolism, arteritis, vascular malformations, among others).

VARVARA [1.3K]

Answer: conditioned

Bobby touches his newborn brother's palm, and his little brother takes hold of Bobby's finger and will not let go. This is known as the conditioned reflex.

Explanation:

A conditioned reflex is a response or behaviour learned after birth. So, once the newborn acquires this learned response, they can perform them even without thinking about it.

Thus, Bobby's brother (the newborn) holding on to his finger and not letting go shows that it is a conditioned reflex
