Why do people feel fireworks before hearing it?

Answers

Answer 1

Answer:

People feel fireworks before hearing it because light travels faster than sound.

Explanation:

We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

Which of the following is found in both cellular respiration and
photosynthesis?
A. Glycolysis
B. The Calvin Cycle
C. The Krebs Cycle
D. Electron transport chains

Answers

ANSWER: D

In photosynthesis, the electron transport chain occurs at the beginning whereas in cellular respiration, it comes at the end.

The process found in both cellular respiration and photosynthesis is Electron transport chain.

Photosynthesis is the process whereby green plants obtain their food using energy from sunlight.

Cellular respiration is the process whereby living organisms obtain energy by breaking down food molecules in their cells.

Photosynthesis occurs in the chloroplast organelle where a process called electron transport chain (ETC) synthesizes ATP (energy).

The process of ETC occurs in the mitochondria organelle, which is the site of cellular respiration.

Therefore, process found in both cellular respiration and photosynthesis is Electron transport chain.

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.

Which of the following is not a true statement about seed bearing plants?

The wind and animals can plant the seed in different locations.
Some seed bearing plants produce flowers.
Seed bearing plants produce spores.
Some seed bearing plants produce cones.

Answers

Answer:

Seed bearing plants produce spores is not a correct statement.

Explanation:

The plants have different mechanisms of reproduction. The more primitive plants, for example, tend to reproduce through spores that are dispersed over a wide area by the wind. The plants that evolved later in history tend to produce seeds through which they reproduce, and the seeds can be dispersed in numerous different ways.

Some of the plants that bear seeds produce flowers, some fruits or vegetables, while some cones. The reason why they produce such things is to be more attractive for animals because by eating or getting near them the animals manage to disperse the seeds over a wide area. The plants of this type that have the smallest seeds don't really need animals though, as the wind is able to easily pick up and move their seeds around with ease.

Answer: best guess: A. The wind and animals can plant the seed in different locations.

Explanation:

Given parameters:

Force applied  = 8.2N

Work done  = 28.7J

Unknown:

Distance through which the force was applied  = ?

Solution:

Work done is the force applied on body to move it through a particular distance.

 Work done   = Force x distance

 Now insert the parameters and solve;

          28.7  = 8.2 x distance

           distance  = 3.5m
