Biology

Bogdan [553]3 years ago

Bird skeletons are very delicate, and therefore, difficult to be preserved.  The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.

Which type of tide occurs when a coastline is within a tidal bulge?
Gekata [30.6K]

<span>Answer: B) Low tide
</span>

<span>There are two types of tides created by the gravitational force of the moon: the high and the low. The one which occurs when a coastline is within a tidal bulge is the low tide.

Wei W, Zhao H, Wang A, et al. A clinical study on the short-term effect of berberine in comparison to metformin on the metabolic
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.

John wants to show the evolutionary relationship between a lion and a cat and group them based on their similarities and a commo
kakasveta [241]
<span>John can use Cladistic Analysis as an approach to trace the classifications of the lion and cat because he can trace a common ancestor for them due to the cat and the lion having the same characteristics and traits. They are considered to be closely related because they share a common ancestor which means that they are closely connected. The earliest discovery of using this method was by Peter Chalmers Mitchell in 1901 as he was studying how different types of birds belong to the same ancestry.</span>
