The sliding filament theory explains how muscles in the human body contract to produce force.

Scientists discover that under de microscopy changes in the sarcomeres as muscle tissue, they observed that during contraction one part of the sarcomere arrangement (named the "A band") remained in constant length. This band contains myosin filaments. On the other hand, the band that changes length is composed of actin filaments

Answer:

When a child is formed, they get half of their genes or traits from each parent. These genes are like tiny sets of instructions that determine things like a child's hair color, eye color, and height. Each parent contributes their genes through their sperm or egg. For example, if a parent has brown eyes, they will contribute a gene for brown eyes to their child. If the other parent has blue eyes, they will contribute a gene for blue eyes to the child.

However, not every trait from each parent will appear in the child. Some traits are dominant, which means they will show up even if only one parent contributes that gene. Other traits are recessive, which means they will only show up if both parents contribute that gene. And sometimes, traits can be a combination of both parents' genes.

In terms of human reproduction, we are the result of sexual reproduction. This means that an egg from a female and a sperm from a male combine to form a zygote, which eventually develops into a fetus and then a baby. Each parent contributes half of their genetic material to the child, resulting in a unique combination of traits.

Explanation:

A child inherits traits from both parents through a process known as genetic inheritance. Humans have two sets of chromosomes, one set inherited from the mother and one from the father. Each set contains genes that determine various traits such as physical characteristics, eye color, hair type, and many others.

Each parent contributes their traits to the child through the genes on their respective chromosomes. Traits are typically determined by the combination of alleles. For example, if the mother has a gene for brown eyes and the father has a gene for blue eyes, the child may inherit one allele for brown eyes and one allele for blue eyes.

During reproduction, the parents' genetic material combines through the process of fertilization. The father's sperm carries genetic information in the form of chromosomes, while the mother's egg also contains chromosomes. When the sperm fertilizes the egg, their genetic material combines to form a unique set of chromosomes in the resulting zygote.

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

The image represents the continental-continental boundary. When two continental plates collide, that's another kind of convergent plate boundary. The continental lithosphere is very thick and has a low density. The continental lithosphere cannot subduct. So when two mainland plates impact, they simply crush together.

Plate tectonic boundaries come in three varieties: plate boundaries that are transformed, divergent, and convergent. The three primary types of plate boundaries are depicted in this image: transform, convergent and divergent.

Based on the information in the problem, the clinical phase of the study which is centered on migraine is Phase 3.

Recurrent headaches of moderate to severe intensity, which can be accompanied by symptoms like nausea and vomiting as well as sensitivity to light and sound, are the hallmark of the headache illness known as migraine. Migraines can greatly affect everyday activities and quality of life and last anywhere from a few hours to several days.

Phase 3 trials are designed to test the effectiveness of a treatment in a larger population, typically involving several hundred to several thousand participants, and are conducted after preliminary evidence of efficacy has been demonstrated in Phase 2 trials.

Adults with more than a 12-month history of migraines were assigned randomly in a double-blinded study to receive treatment with experimental drug X (10 or 20 mg/day) or placebo. The primary efficacy measure was the reduction in severity of the migraine attacks. Enrollment was 1200 subjects. Which of the following best describes the clinical phase of this study?

A line graph is a type of chart that displays data as a series of points connected by lines.

The horizontal axis represents the independent variable or time, while the vertical axis represents the dependent variable or numerical values being measured. Each data point is plotted on the graph, and lines are drawn to connect them, creating a visual representation of the data's trend or pattern over time or across different categories. Line graphs are commonly used to show trends, changes, or comparisons over continuous intervals.

On the other hand, a bar graph is a chart that uses rectangular bars of varying lengths to represent different categories or data points. The height of each bar corresponds to the value it represents, and the bars are typically arranged along the horizontal or vertical axis to provide a visual comparison between categories or data sets. Bar graphs are often used to display categorical or discrete data and make it easy to compare values between different groups or variables.

An independent variable is a variable that is changed or manipulated in a scientific experiment to examine how it affects the dependent variable.

Relies on the variables you're using and the functions connecting them. A variable is dependent or independent, depending on whether its value changes as a result of a change in another variable.

In a scientific experiment, an independent variable is a variable that is altered or controlled to see how it impacts the dependent variable.

The variable being tested and measured in an experiment is referred to as the dependent variable.

Explanation:

In complete dominance, the dominant allele hides the expression of the recessive one when they are together in the same genotype. 1) a- 100% will have short hair. b) 0% long hair. 2) Both parents are heterozygous, Ss.

Complete dominance is an inheritance pattern that occurs when the dominant allele completely masks the recessive allele.

The presence of at least one dominant allele in genotypes is enough to express the dominant pahenotype.

In the exposed example,

1)

Cross 1: one heterozygous with a homozygous dominant

Parentals) Ss   x   SS

Gametes) S   s     S    S

Punnett square)     S      s

                         S   SS    Ss

                         S   SS    Ss

F1) Genotype

    Phenotype

1) a- 100% of the progeny will have short hair

1) b- 0% of the progeny will have long hair

2)

Cross 2: between two short-haired individuals

F1) 25% long-haired individuals

If among the progeny both phenotypes are expressed, it means both parents carry the recessive allele in their genotypes, otherwise only the dominant phenotype would appear.

Parents) Ss   x   Ss

Gametes) S   s    S    s

Punnett square)    S      s

                       S    SS    Ss

                       s    Ss     ss

Thousands of scientists have found that (B) exercise helps virtually every age-related condition that people encounter.

Early adulthood is considered a new stage in life between adolescence and early adulthood, which lasts around 18 to 25 years. Five characteristics of adulthood emerge: exploration of identity, instability, self-focus, feelings between adolescence and adulthood, and a sense of vast future possibilities. Adulthood emerges mainly in industrialized countries, where most young people are educated and where the median age of marriage and childbirth is around 30 years old. Emerging adulthood varies across industrialized countries. It lasted longest in Europe, while in industrialized Asia freedom from emerging egocentrism in adulthood was balanced by obligations to parents and conservative views on sexuality.

Exercise helps with weight loss and weight loss maintenance. Exercise increases your metabolism or the number of calories you burn each day. It can also help you maintain and increase lean body mass, which can also help increase the number of calories you burn each day.

In non-industrialized countries, emerging adults, although present only among middle-class elites, are expected to grow in the 21st century as these countries become more prosperous.

According to the rule of conservation of mass, matter cannot be generated or destroyed in a closed or isolated system. It is preserved but capable of changing forms.

The understanding that substances do not actually vanish as a result of a reaction, despite what might appear to be the case, but rather change into another material of equal mass, was made possible by the law of conservation of mass, which was essential to the development of chemistry.

The law of conservation of mass was discovered by several scientists, according to history. As a consequence of an experiment in 1756, Russian scientist Mikhail Lomonosov recorded it in his diary.

French chemist Antoine Lavoisier carefully recorded experiments that supported the law in 1774. Some people refer to the law of conservation of mass as Lavoisier's Law.
