Given two areas with equal sunlight and available water. Areal has a high amount of atmospheric carbon dioxide while Area II has
a low amount of atmospheric carbon dioxide,
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.

What is one of the most important forms of energy? Give two examples of how this type of energy is used in our lives.
Answer:
Electrical energy Explanation:
We use it to charge our phones and important devices. We also use it to power almost everything.
Answer:
Kinetice-the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Electriacl -Electrical energy is the energy carried by moving electrons in an electric conductor. It is one of the most common and useful forms of energy.

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.

Answer: Angiosperms are the plants which produce flowers for sexual reproduction.
Explanation:
In the angiosperm life cycle the following events occur:
1. Seed germination: Under suitable condition inside the soil obtain water, oxygen and minerals the seed germinates and from the two precursors plumule from where the stem emerge and radicle from where the root emerges.
2. Mature plant with flower: The plant gets matured with the develop of root and shoot and from the shoot the bud originates which produces the flower.
3. Pollination: During the process of pollination a mature pollen grain is transferred towards the female reproductive structure typically the stigma receives the pollen grain.
3. Fertilization of pollen with egg in ovary: The pollen is the male gametophyte which develops in the anthers which are the male reproductive structure of the flower and the egg or ovule is the female gamete which develops inside the ovary or female gametophyte. The fusion of male gametes provided by the pollen grain with that of the ovule is called as fertilization.
4. Formation of fruit with seed: After the fertilization process the ovules develop into seed and the ovary into fruit.
5. Seed dispersal: The fruit gets detached from the plant and it may get rotten and dried the dried seeds disperse and may germinate in favorable conditions.
How are solids, liquids, and gases of the same element different from each other?
Answer:
Comparison Chart
BASIS FOR COMPARISON SOLID LIQUID GAS
Meaning Solid refers to a form of matter which has structural rigidity and has a firm shape which cannot be changed easily. Liquid is a substance, that flows freely, having a definite volume but no permanent shape. Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in.
Shape and Volume Fixed shape and volume. No fixed shape but has volume. Neither definite shape nor volume.
Energy Lowest Medium Highest
Compressibility Difficult Nearly difficult Easy
Arrangement of molecules Regular and closely arranged. Random and little sparsely arranged. Random and more sparsely arranged.
Fluidity Cannot flow Flows from higher to lower level. Flows in all directions.
Molecular motion Negligible molecular motion Brownian molecular motion Free, constant and random molecular motion.
Intermolecular space Very less More Large
Intermolecular attraction Maximum Medium Minimum
Sound speed Fastest Faster than gas but slower than solid Lowest among all
Storage Don't need container, for storage. Cannot be stored without container. Needs closed container for storage.

Answer: The correct option is
E. a woodpecker using his sharp beak
Explanation:
This is because a structural adaptations refer to characteristics or traits that animals possess and they use in order to adapt or survive in their environment. These refer to the physical characteristics of the animals.
From the question, a wood pecker using a sharp beak is an example of structural because the beak is the characteristics the wood pecker is using to survive in it's environment.

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.

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.

Explanation:
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.
