What is the correct order of development (from first stage to last)?

Biology
1 answer:
natka813 [3]2 years ago
3 0

The correct order of development is after fertilization Zygote→Blastocyst→Embryo→Fetus. A zygote forms as a result of fertilization. It then rapidly divides, becoming a blastocyst, then an embryo, and finally a fetus.

  1. Zygote
  2. Blastocyst
  3. Embryo
  4. Fetus

<h3>What are the stages of fetal development?</h3>

  • Fertilization.
  • Blastocyst development.
  • Embryo development.
  • Development of the fetus and placenta.

If a enters the egg, fertilization takes place. Tiny cilia that line the fallopian tubes propel the fertilized egg (zygote) through the tubes to the uterus. The cells of the zygote divide several times as it travels through the fallopian tube to the uterus. The zygote enters the uterus within three to five days.

Once inside the uterus, the cells continue to divide and become a hollow sphere called a blastocyst. The blastocyst implants in the wall of the uterus approximately six days after fertilization.

With this information, we can conclude that A baby goes through several stages of development, starting with the fertilization of the egg. The egg develops into a blastocyst, an embryo, and eventually a fetus.

1. What is a double helix?
RUDIKE [14]

Answer:

1. Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.

2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.

3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.

5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA

Hopes this helps.

Describe the role of each of the following mechanisms in determining an individual’s eating habits and body weight.• Biological
alina1380 [7]

Answer:

Explanation:

1. Biological Mechanism: This are things like hunger, appetite and taste of the individual. Every individual is unique and one's hunger and appetite determines how often and how much they eat respectively. The higher these are, the more likely they are to consume calories. The taste is even more relevant as it speaks to what kind of food the individual likes, is it high calorie or low? Is it fat rich or low fibre? Etc.

Learning Mechanism: This are relevant mostly to students. Studying patterns greatly affect eating habits and body weight. Time of sleep, stress patterns, balanced diet and even regularly missing a meal for a study group directly affects metabolism patterns. For instance, eating breakfast regularly boosts metabolism, and is good for weight balance.

Reinforcement: Certain foods are quite addictive and so reinforce their consumption by adjusting brain chemistry.

Body or Brain Chemistry: Studies done on Obesity have found that some individuals are susceptible to environmental food cues than others due to differences in brain chemistry that make eating more habitual and less rewarding. This means that not only do they eat habitually but that it is less satisfying. This is a major contributor to obesity. These Peculiarities in brain/body chemistry affect people's eating pattern and their weight.

Brain Structure Modeling: Uncontrolled eating is also positively associated with gray matter volume (GMV) of the cerebellum, and negatively associated with the Gray matter volume on the left side of the anterior cingulate cortex, middle cingulate cortex, and supplementary motor areas. What this means is that individuals with more gray matter volume in these areas of their brains are more presdusposedto excessive eating habits and this might lead to weight problems and it's related health risks.

Genetic Factors: These factors are genetic predisposition to eating disorders, genetic influence on taste, meal selection and appetite processing.

These also influence how much the individual ends up eating and what type of food they eat.

Cultural Factors: This include type of food found in one's culture, polite eating habits there, the ingredients used for cooking said culture. It also encorporatea the individual's class as food poverty is known to exist affecting about 14 million people. There's also available and affordability of healthy food options. This affects both eating habits and weight as less healthy junk food are more likely to be calorie dense.

PS: The eating pattern and body weight factors are closely correlated as the eating pattern explains what the weight situation might mirror.
