Answer:
<u>Origin:</u> In biology, origin can be described as the location where the muscle joins a stationary bone and as a result, no movement occurs.
<u>Insertion: </u>In anatomy, insertion can be described as the point of attachment which allows movement of a bone to occur. It moves when the muscles contract.
<u>Tendon:</u> In biology, the tendon can be described as a type of connective tissue which attaches a bone to a muscle.
The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.
Answer: <u>Option C, they digest pathogens</u>
Explanation: Monocytes are involved in the process of digesting pathogens and infected cells, termed as phagocytosis.
Monocytes don't produce antibodies, only B cells can produce antibodies. So, option A and D are incorrect. Also they appear colorless when observed under the microscope. They don't appear granular, so option B is also incorrect.
Answer:
This exercise is incomplete, missing the value of k (decay constant), which is equal to 4x10⁻⁸s⁻¹ at 25°C
The answer is 0.549 years
Explanation:
Given:
first order of reaction
k = 4x10⁻⁸s⁻¹
For a first order of reaction, the half-life time for the degradation of DDT is equal to:
Changes to the classification system have meant that the classification of some species of organisms has changed too. The system had to be changed to incorporate this new group or organisms.
