The lymphatic system has multiple interrelated functions: It is responsible for the removal of interstitial fluid from tissues. It absorbs and transports fatty acids and fats as chyle from the digestive system. It transports white blood cells to and from the lymph nodes into the bones.
Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.
Answer:
Plants exchange two gases in the atmosphere i. e. oxygen and carbondioxide. Carbondioxide is entered into the plant body through small opening called stomata which are present on the surface of leaves. Carbondioxode is used as a raw material in the process of photosynthesis. Oxygen is produced in the end of photosynthesis process and releases in the atmosphere.
Answer:
They act to regulate the expression of specific genes (androgen-responsive)
Explanation:
Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".
Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.
This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.
This process helps to direct the development of male sexual characteristics.
The antibiotic called ampicillin was not effective against E.coli.
Answer: D
Explanation:
E.coli is normal microbial flora which is present in the gut of the mammals.
It is gram negative bacteria and very few strains of this bacteria causes harm.
Antibiotics are the chemical drugs which are used to treat the microbial infection either by killing the causative organism or by its growth inhibition.
Antibiotics such as neomycin, penicillin and erythromycin are usually used to treat E.coli infection.
Antibiotic such as Ampicillin is not used as the bacterium E.coli is highly resistant to it.
