The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.

Explanation:

There are mainly three types of key pigments in photosynthesis.  These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.

The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.

marshall27 [118]

A group of Chinese women with PCOS who were receiving treatment saw several metabolic and hormonal imbalances improve after taking BBR. The primary consequences may be connected to the modifications in body composition in obesity and dyslipidemia. For the evaluation of the possible beneficial metabolic effects of BBR in women with PCOS, additional controlled trials are required.

PCOS:

  • Objective: Insulin resistance is a common metabolic and reproductive condition called polycystic ovarian syndrome (PCOS) (IR). A quinoline derivative alkaloid known as berberine (BBR) has been utilized as an insulin sensitizer and is isolated from Chinese medicinal herbs. There may be a therapeutic benefit for PCOS from BBR. The purpose of this study was to compare the effects of BBR and metformin (MET) on the metabolic characteristics of PCOS-affected women.
  • Design and methods: Ninety nine PCOS and IR patients were randomly assigned to one of three therapy groups: BBR+ compound cyproterone acetate (CPA;n=31), MET+CPA(n=30), and placebo+ CPA (n=28) for 3months. Before and after the treatment period, metabolic and hormonal measures as well as the clinical characteristics of the women were evaluated.
  • Results: Reduced waist circumference, waist-to-hip ratio (WHR;P<0.01), total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDLC; P<0.05), as well as increased levels of high-density lipoprotein cholesterol (HDLC) and sex hormone-binding globulin (SHBG; P<0.05) were all observed following treatment with BBR as compared to MET. Similarly, BBR treatment decreased WHR, fasting plasma glucose, fasting insulin, homeostasis model evaluation for IR, area under the insulin curve, TC, LDLC, and TG (P<0.05), while increasing HDLC and SHBG (P<0.01) as compared to placebo.

Small insects such as the water strider can walk on water because their weight is not enough to penetrate the water's surface.
White raven [17]

Answer:

B

Explanation:

Surface tension allows a water strider to "walk on water"

Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. ( :
