Answer:

The correct answer is: A. active transport requires energy.

Explanation:

Active transport can be defined as the physiological process by which molecules are enforced to migrate from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This occurs by the expenditure of energy. This type of movement is usually carried out by the integral membrane transport proteins or carrier proteins those remain interspersed across the plasma membrane.
Passive transport can be defined as the physiological process in which no energy expenditure is required. This is because in this form of transport, molecules move from a region where their concentration is high to a region where their concentration is low, that is, down the gradient of their concentration, across a semi-permeable membrane. This type of movement can be mediated by simple diffusion or with the help of membrane transport proteins.

Describe two observations a scientist could make about the leaf, cells, and chloroplasts shown.

Answer:

Leaf cells contain chloroplasts. Photosynthesis happens in the chloroplasts as they hold vitality from the sun. Chloroplasts contain chlorophyll, which influences leaves to seem green.

The tissues of the leaf in the middle of the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be additionally separated into two layers, the palisade layer, and the springy layer, both of which are stuffed with chloroplasts, the production lines of photosynthesis.

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 $3$ months. 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.
