Which hypothesis regarding the evolution of hominin bipedalism suggests that this energy-efficient trait arose so that hominins

could search for food that was dispersed after climatic changes at the end of the Miocene?

Answer:

Patchy forest.

Explanation:

The patchy forest hypothesis is the second hypothesis that helps to explain the origin of the hominids. The hypothesis was developed by  Peter Rodman and Henry McHenry.

This hypothesis suggest that the evolution of bipedalism is energy efficient in the environment that contain few tress. The patchy forest result in the dispersion of the forest and this might result in the energy efficiency of bipedalism by walking upright and collect their food with hands.

Thus, the correct answer is patchy forest.

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.

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes.
UkoKoshka [18]

B.  New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

Explanation:

The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.

Cellular respiration is classified as an catabolic  process in which an energy rich substance is broken down into a lesser one.

  • Metabolic processes are usually divided into catabolic and anabolic processes.
  • In catabolic step, energy is broken down.
  • Cellular respiration is catabolic whereas photosynthesis is anabolic.
  • The new compounds formed have lower energy bonds after respiration.
