Replanting trees on a bare hillside is an example of
(A) conservation and afforestation
(B) preservation and conservation
(C) restoration and preservation
(D) reafforestation and restoration
Answer:
(D) Reafforestation and restoration
Explanation:
Replanting trees in helping to "re-forest" the hill and restore it to how it was before.
Replanting trees in a place where trees used to exist is an example of reafforestation and restoration.
Afforestation means to create a forest (trees) where they do not exist before.Reafforestation, on the other hand, means to create a forest (by planting trees) to an area that used to be a forest but has been removed due to one reason or another. Similarly, restoration means restoring an area to what it used to be. Forest restoration is the practice of restoring a forest that has been modified by natural or anthropogenic processes to its old self.Thus, replanting trees on a bare hillside is an example of reafforestation and restoration.

Explanation:
A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases
Answer:
A.Blood volume decreases
Explanation:
Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.
Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.
This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

O A. Second law of thermodynamics
O B. Efficiency of a heat engine
O C. Work done by a gas
O D. First law of thermodynamics
SUBMI
Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
U is the internl energy of the system. ΔU is the change in U. Q refers to the total heat supplied into the system (include both addition and release of energy in the system). W is the net work done by the system.Hence, the correct option is D.
Answer:
Option D, First law of thermodynamics
Explanation:
The first law of thermodynamics states the following -
[tex]dU = Q-W[/tex]
where dU represents the Heat added to the System
Q represents the Change in Internal Energy OR net heat transfer OR sum of all heat transferred into and out of the system
W represents the Work done on the system
The first law of thermodynamics is based on the application of the conservation of energy principle to heat and thermodynamic.
hence, option D is correct

. Your lab technician was to determine the ash content of buttermilk by conventional dry ashing. The technician weighed 5 g of liquid buttermilk into one weighed platinum crucible, immediately put the crucible into the muffle furnace using a pair of all stainless steel tongs, and ashed the sample for 48 h at 800 °C. The crucible was removed from the muffle furnace and set on a rack in the open until it was cool enough to reweigh. (4 marks)
a. What errors were made in the preceding method (there were several)?
b. What were the likely results of these errors?
Answer:
Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications
The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.
a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:
Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.The sample should be ashed for 12-18 hrs , more than this can damage the required ash content.platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.b. The result that occur due to above errors such as the temperature, time, tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.

Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

a. Exchange of ADP and ATP on the pyruvate dehydrogenase complex.
b. AMP binding to and activating the enzyme.
c. Phosphorylation by ATP, which turns the complex on, and dephosphorylation, which turns the complex off.
d. Phosphorylation by ATP, which turns the complex off, and dephosphorylation, which turns the complex on.
Answer:
d. Phosphorylation by ATP, which turns the complex off, and dephosphorylation, which turns the complex on
Explanation:
Pyruvate dehydrogenase complex (PDC) is a complex enzymes which is responsible for the conversion of pyruvate into acetyl-CoA, NADH and CO2 through oxidative decarboxylation.
Pyruvate dehydrogenase is one of the main component of PDC that catalyze conversion of pyruvate to acetyl-CoA. Pyruvate dehydrogenase (PDH) enzymes is first modified by covalent modification in the pyruvate dehydrogenase complex. Pyruvate dehydrogenase kinase undergo phosphorylation with ATP and inactivates PDH which turns the complex off. then the pyruvate dehydrogenase phosphatase support dephophorylation which turns the complex ON.
Hence, the correct option is d.

Answer:
The correct answer is: the bright sunlight.
Explanation:
The bright sunlight on a sunny day is the stimulus that causes the response of squinting, which is necessary for us to protect our eyes from different conditions that can be caused by extreme sun exposure.
This stimulus is transmitted to the Central Nervous System by sensory neurons, so the information can be processed in the brain and the response to squint our eyes to receive less light can be performed by the orbicularis oculi muscle (the one that closes the eyelids).
Answer:
the bright sunlight

The tube for S. sonnei shows a yellow butt, pink slant with no gaps or breaks in the medium and no black precipitate 3. The tube for E. coli shows a yellow butt, yellow slant with no gaps or breaks in the medium and no black precipitate Which of these organism can reduce glucose but not lactose and/or sucrose?
Answer:
Test Tube 2 (S. sonnei)
Explanation:
Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.
The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.
When the bacteria ferment any of the three sugar, the medium turns yellow.
In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.
In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.
In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.
Thus, test tube 2 (S. sonnei) is the correct answer.
