Does carbon make up an amino acid?

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interac

Answer:

100% yellow fruit color, Yyww.

Explanation:

Available data:

two independently assorting genes

the W allele codes for a dominant white phenotype

w allele codes for a colored squash

The allele Y codes for a dominant yellow phenotype

the allele y codes for a recessive green phenotype

The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is dominant, the interaction is known as "dominant epistasis".

W suppresses the expression of Y and y, this means that whenever W is present, the fruit is white. If W is not present, the fruit color can be expressed.

So, the proposed cross in the present problem occurs between a green fruited individual and yellow fruited individual, which suggests that W is absent.

Genotype for Green fruit: yyww

Genotype for purebred Yellow fruit: YYww

Cross:

Parental) YYww x yyww

Gametes) Yw Yw Yw Yw yw yw yw yw

Punnet square) Yw Yw Yw Yw

yw Yyww Yyww Yyww Yyww

F1) 100% Yellow fruited plants, Yyww

As these two genes assort independently, we can also represent the cross for each gene by separate, like this:

For w gene:

Parental) ww x ww

Gametes) w w w w

Punnet square) w w

w ww ww

F1) 4/4 or 100% colored-fruits

For Y gene:

Parental) YY x yy

Gametes) Y Y y y

Punnet square) Y Y

y Yy Yy

F1) 4/4 or 100% yellow fruits, Yy.

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.

How many neutrons does element's x have if it's atomic number is 52 and it's mass number is 153?

Over [174]

Answer: 101 neutrons

An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.

Hope this helps! :)

What causes antibiotic resistance?

Rama09 [41]

Answer:

Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.
