Finger [1]3 years ago
4 0

Red tide is a common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae (e.g. dinoflagellates and diatoms). The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events.

zhenek [66]

Answer: d) lightheadedness or unconscious episodes.

Explanation:

There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:

1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.

2. The stage of resistance- this occurs till the stress is removed.

3. The stage of exhaustion

What is the expected phenotypic ratio for feather colour if two chickens with blue feathers are crossed
ss7ja [257]

Answer:

The correct answer is - 1:2:1 for black : blue : white chicken.

Explanation:

We know that color of the feather is a trait of the chicken that shows the codominance type of inheritance pattern where both forms of the trait are dominant and make a mix of the forms. In this case, blue is heterozygous BW and black BB and white is WW, then crossed between BW with BW

gametes: B, W and B, W

Punnett

           B       W

B        BB      BW

W        BW     WW

thus, the phenotypic ration is - 1 black : 2 blue : 1 white
