Answer:
C. By creating laws or traditions that regulate hunting and fishing
Explanation:
Wildlife resources refer to wild animals (terrestrial, aquatic etc) in their natural habitat. Wildlife is an integral part of our society, however, they are being overexploited by human activities.
According to the options in the question, one way to address the problem of over use of wildlife resources is by creating laws or traditions that regulate hunting and fishing. Laws that compel hunting and fishing, which are the means humans over use wildlife, will help bring the rate at which these resources are used.
For example, creating a law that prohibits hunting in certain areas will help preserve wildlife in that area because it is a punishable offence by the law to hunt. Hence, wildlife resources will be preserved.
Answer:
The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.
Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.
<em>BMR calculation = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)</em>
<em>In</em><em> </em><em>Harris Benedict Equation, </em><u><em>BMR</em></u><em> is </em><u><em>multiplied</em></u><em> by </em><u><em>activity factor </em></u><em>to determine calories need.</em>
The activity factors in Harris Benedict Equation are:
for no exercise = 1.2
exercise for 1 to 3 days/week or light exercise = 1.375
exercise for 3-5 days/week or moderate exercise = 1.55
exercise for 6-7 days a week or hard exercise = 1.725
exercise for 2 times training = 1.9
<u>So, calculation for my calorie needs is as following:</u>
BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945
Calorie needs = BMR x 1.55
= 974.945 x 1.55
= 1511.16 calories
Smart home technology is the general term given to basic home amenities that have been fitted with communication technology, enabling some degree of either automation or remote control. It includes things like Home security systems. Environmental controls, like air conditioning, heating, and lighting.
Explanation:
Environmental controls, like air conditioning, heating, and lighting.A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample The solution for space exploration is through using mass spectrometers which are used to identify miniature particles present in space. Mass spectrometers are also used in radioactive and carbon dating. When used with gas chronographs, mass spectrometers detect traces of toxic particles and contaminants in air.
1. The correct answer is: The viral envelope proteins interact with CD4 and a co-receptor on the cell membrane.
Binding and entering the host cell are the first steps of the HIV virus infection. So, these steps play a major role in determining the ability of HIV to degrade the human immune system. Binding of HIV to CD4+ T lymphocytes (express chemokine receptors CCR5 and CXCR4 called co-receptors) triggers the fusion of the viral and host cell membranes, initiating infection (viral core gets into the cytoplasm).
Attachment of the virion can be:
• Nonspecific-envelop protein of the virus (Env) binds to cell-surface heparan sulfate proteoglycans
• Specific-Env binds to integrin.
2. The correct answer is: Activation of the host cell by cytokines, growth factors, or antigens.
After the viral capsid enters the cell, single-stranded RNA genome is released from the attached viral proteins and copied it into a complementary DNA (cDNA) molecule thanks to an enzyme called reverse transcriptase. Next step is the integration of the viral DNA into the host cell's genome. This process is done by another viral enzyme called integrase. The integrated DNA is transcribed into RNA and then translated into proteins that will help the package of new viruse particles.
3. The answer is: false
Reverse transcriptase is an enzyme that catalyzes the formation of DNA from an RNA template. Since the genome of the virus (HIV) is single stranded RNA, reverse transcriptase copies it into a complementary DNA (cDNA) molecule. Thanks to this enzyme, formed cDNA can be integrated into host’s genome. Because of this proprety, antiretroviral drugs used to treat HIV infection work as reverse-transcriptase inhibitors.
