Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

What is a hormone?Hormones are a class of signaling molecules found in multicellular organisms. These molecules are sent to distant organs by complex biological processes in order to regulate physiology and behavior. Hormones are also known as endocrine signaling molecules. Hormones are essential for the proper development of all organisms, including fungi, plants, and animals.
There are three primary categories of hormones: those derived from lipids, those derived from amino acids, and those derived from peptides.

Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

The heating of the Earth's surface and atmosphere by the Sun drives convection within the atmosphere and oceans.
Convection produces winds and ocean currents.
What is the BEST explanation of what causes stronger wind patterns?
The greater the pressure differences between a low-pressure area and a
high-pressure area, the stronger the winds.
B)
The lesser differences between a low-pressure area and a high-pressure
area, the stronger the winds.
The solar energy and convection currents do not influence winds.
D)
The sun's energy has no effect on wind patterns.
Answer: Option A
Explanation:
Convection is the process by which heat is transferred from a hotter body to a colder body. It usually occurs in liquids. The movement of hot air up and cold air down helps in heat transfer.
The sun helps the heat transfer between the water( ocean ) and atmosphere and due to this there is a difference in the pressure.
The warm water also makes the atmosphere warm and is less dense and has less pressure and meanwhile the colder air is more dense has high pressure.
The warm air rises up and cooler air move to the place of warmer air and this movement of warmer and colder air creates difference in pressure and leads to formation of wind. The more will be the difference , stronger will be the wind patterns.
what is the tendons structure?
Answer: A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Answer:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Explanation:
Tendons are composed of multiple bundles, fibroblast, and dense linear collagen fibrils, which form the macroscopic structure of tendons and give the appearance of fibrous. In general, connective tissue surrounding the tendons allows some friction.

How does the rate of photosynthesis in Area I compare to that in Area 11?
A)
Atmospheric carbon dioxide has no affect on the rate of photosynthesis.
B)
The rate of photosynthesis increases with a decrease in carbon dioxide.
The rate of photosynthesis increases with an increase in carbon dioxide.
D
The level of carbon dioxide increases with the level of available oxygen.
14)
Which microscone would he MOST useful for
Answer:
C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.
According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.

Bradley decides one day to run a marathon without any training after 10 minutes is lapsed and Bradley has read half a mile he begins to get cramps in his dies he is also breathing very rapidly what is causing the cramps in Bradley‘s legs
Answer: The reason for the cramps in Bradley's legs are due to anaerobic respiration that has occured in the muscles and also the formation of lactic acid.
Explanation:
The reason for the cramps in Bradley's legs are due to anaerobic respiration that has occured in the muscles and also the formation of lactic acid. This could have been prevented if he had trained before running the marathon as thus will help in providing the muscles with strength.
We should note that in anaerobic respiration, glucose is being broken down without oxygen which is then passed on to the cells. Anaerobic respiration produces lactic acid.

An airplane flies with a constant speed of 768 km/h. How long will it take to travel a distance of 2496 kilometers?
Answer:
The correct answer is - 3 hours 15 minutes.
Explanation:
Given:
Speed = 768 km/h
distance = 2496
Solution:
Converting speed in km/minutes:
768/60 = 12.8
Now by the formula,
Time = distance/speed
time = 2496/12.8
=195 minutes
converting in hour = 195/60
= 3 hour 15 minutes.
