The timing of human puberty is strongly linked to genetic and dietary factors. It is also linked to historical changes, and a secular trend favoring early menarche has resulted in an ever increasing proportion of teens attaining reproductive capacity at young ages. The causes of the trend, however, have not been unequivocally ascertained. More generally, we know very little about the factors in children's proximal environments that either inhibit or accelerate the timing of pubertal maturation. But, between 1984 and 1987, it has been distributed a survey with questionnaires to over 1,000 participants who were asked about their early family experiences and their physical development. The results from this retrospective study suggest that parental absence especially the absence of the biological father-is associated with early menarche.
Asexual reproduction. This is mainly because the runner comes from one parent thus there is no genetic diversity in the offspring. They are clones.
Answer:
978,75 Newton metro.
Explicación:
El trabajo realizado es de 978,75 Newton metro cuando la fuerza es de 125 newton, la distancia es de 9 metros y el ángulo es de 60 grados porque cuando usamos la fórmula del trabajo realizado obtenemos esta respuesta. La fórmula del trabajo es fuerza x desplazamiento x Sin (θ). θ muestra la dirección y el ángulo en el que se realiza la fuerza. Entonces, multiplicando todos estos valores obtenemos la respuesta para el trabajo realizado, que es 978,75 Newton metro.
Answer:
False.
Explanation:
The plasma membrane consists of phospholipid bilayer in which the proteins are inserted inside the membrane. Carbohydrates are attached with the lipids and proteins on the plasma membrane.
The phospholipid bilayer do not has solid consistency. The consistency of plasma membrane is fluid like to perform the important function of the cell membrane.
Thus, the correct answer is option (b).
Development of multiple SNP marker panels affordable to breeders through genotyping by target sequencing (GBTS) in maize : SNP of interest.
What is SNP?
SNPs (pronounced "snips"), also known as single nucleotide polymorphisms, are the most prevalent form of genetic variation in humans. Each SNP is a variation in a single nucleotide, the basic unit of DNA. In a specific section of DNA, an SNP might, for instance, swap out the nucleotide cytosine (C) with the nucleotide thymine (T).
SNPs typically occur all over a person's DNA. There are around 4 to 5 million SNPs in an individual's genome, which implies they typically occur almost once every 1,000 nucleotides. Many people have these variants; nevertheless, for a variation to be called an SNP, it must be present in at least 1% of the population. More than 600 million SNPs have been discovered by researchers in human populations worldwide.
