A teacher challenges her students to each build a solar oven using common household materials. The students will then test their designs using thermometers. What engineering problem are they trying to solve?

Answers

Answer 1

Answer:

Climate issues associated with engineering works

Explanation:

A teacher challenging her students to each build a solar oven using common household materials is highly commendable. The students using this method will help in solving the engineering problem of climate issues.

This will help in the reduction of emission of greenhouse gases which causes global warming. Solar energy on the other hand is renewable and free from emission of such gases.

Write the names of any two hormones secreted by the adrenal glands with one function of each

Answers

Cortisol is secreted by the cortical region of the adrenal gland and it increases the blood sugar levels.

Adrenaline is secreted by the medular region of the adrenal gland and it increases the heart rate.

Hey There!_____________________________________[tex]\huge\textbf{Adrenal Gland:}[/tex]

Ad means upon and renal means kidney, thus adrenal gland is present at the top of the kidney. There are two regions in the adrenal gland,

Adrenal Cortex: Outer regionAdrenal Medulla: Inner region

                         x------------------------------------------------------------x

[tex]\Large\textbf{Adrenal Cortex}[/tex]

Adrenal Cortex is active all the time but especially in shock or stress condition. It secretes aldosterone, cortisol and androgenic hormones.

ALDOSTERONE: It promotes the retention of sodium ions and release of potassium ions by kidney. It also promotes inflammation as part of the body immune defense reaction.CORTISOL: It brings about an increase in blood glucose level mainly its production from protein and by antagonizing the action insulin.ANDROGEN: They play an important role in sexual development. As they secrete androgen and testosterone so they promote the secondary sex characters such as beards in men and sexual characters in woman._____________________________________[tex]\Large\textbf{Adrenal Medula}[/tex]

The adrenal emdulla produces the hormones such as adrenaline and nor-adrenaline. Both of these hormones are secreted in stress condition. THey produce many specific changes in the body.

They produce the fight and flight mechanism inside our body. It dilates the blood vessels, promotes the release of glucose from the liver glycogen, reinforces the effects of sympethatic system, dilates the pupil of an eye.

_____________________________________

QUESTION:

The question asks for the two hormones from the adrenal gland, it does not say specifically from which part of the adrenal gland, thus you could mention any hormone from any region of the adrenal gland mentioned above.

How does the cooling rate of magma affect the
texture of igneous rock?

Answers

Answer:

The factor that affects the size of the crystals and the texture of the rock is the cooling rate of the molten rock or magma. If the magma cools rapidly, the crystal formed is very small. ... On the other hand, if the magma cools slowly, the crystal formed is large. This rock has a coarse-grained texture.

Explanation:

The texture of an igneous rock is completely dependent on the rate of cooling of the melt. Slow cooling allows large crystals to form whereas fast cooling gives small crystals.

How is cooling rate of magma related to texture of igneous rock?

If the magma cools quickly then the reactions are much more faster and smaller mineral crystals. Igneous rocks have a distinctive appearance based on the rate of cooling.

Cooling rate of the molten rock or magma is the factor that mainly affects the size of the crystals and texture of the rock. Crystal formed is very small, when the magma cools rapidly whereas, the crystal formed is large, if the magma cools slowly.

Rocks formed from the crystallization of a liquid are called Igneous rocks. Igneous rocks are divided into:

Intrusive rocks that  crystallize from magma in the earth's crust. Extrusive rocks that crystallize from lava in the earth's crust.

The negatives of stem cell research are the cost and ethical controversary. To start, stem cell research could help with diseases like Alzheimer's and certain cancers like Parkinson's. Also since cells replicate incredibly fast, procedures wouldn't need many cells depending on the case. Stem cell research can vary in costs from about $5000 to $20,000 which for many people is difficult because stem cells are very temporary in many cases. Many groups of people don't agree with stem cell research since human embryos are destroyed in the process of harvesting embryonic cells and it is "potential life".

Answers

Answer:

Light energy is converted to chemical energy.

Please find the explanation below

Explanation:

Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.

The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.
