Which two structures are first to combine in translation?

Answer:

D

Explanation:

These include voice changes, body shape, pubic hair distribution, and facial hair.

Breast development. changes in body shape and height. growth of pubic and body hair. the start of periods.

The first places to grow are the extremities (head, hands, and feet), followed by the arms and legs, and later the torso and shoulders. This non-uniform growth is one reason why an adolescent body may seem out of proportion. During puberty, bones become harder and more brittle.

During adolescence, individuals experience puberty, marked by an adolescent growth spurt, sexual maturity, and the development of primary and secondary sexual characteristics. These changes are regulated by hormones and result in noticeable physical transformations.

During adolescence, a number of significant body changes occur as part of the developmental process. Adolescence is identified by the onset of puberty, during which individuals experience a series of physical and hormonal changes that lead to sexual maturity. One notable change is the adolescent growth spurt (AGS), a period characterized by rapid growth in height and weight, and changes in body composition and proportions.

Further developments during puberty include the maturation of primary and secondary sexual characteristics. Primary sexual characteristics involve the organs needed for reproduction, such as the uterus and ovaries in females, and the testes in males. Secondary sexual characteristics are indicative of sexual maturation but do not directly involve the reproductive organs, such as the development of breasts and hips in females, and facial hair and a deepened voice in males. These changes are controlled by a complex release of hormones including GnRH, LH, FSH, testosterone in males, and estrogen in females.

Therefore, the correct answer to the question 'Which body changes occur during adolescence?' is D) growth spurts, puberty, and sexual maturity.

Answer:

One similarity between the sunflower plant and paddy plant is that both of them have a non-woody stem. The three differences are; sunflower plant is a dicot, and has branching veins and taproots while paddy plant is a monocot, and has parallel veins and fibrous roots.

Explanation:

The paddy plant is a monocot (monocotyledon), where only one embryonic leaf (cotyledon) is present inside the seed coat. The monocots have a fibrous root system and their leaf veins are parallel. The sunflower plant is a dicot or dicotyledon, which contains two embryonic leaves inside the seed coat. The leaf veins of dicots are branched. They have taproots. Both the sunflower plant and paddy plant can be used as food. Both have a non-woody stem.

Answer:

stem cells

Explanation:

Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.

Unspecialized human cells are known as stem cells. They have the unique ability to produce more cells of the same type, and under certain conditions, to specialize into more specific cell types.

Unspecialized human cells are called stem cells. Stem cells are unique because they are unspecialized cells capable of renewing themselves through cell division, and under certain physiological or experimental conditions, they can be induced to become tissue or organ-specific cells with special functions. Stem cells serve as a sort of repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem and progenitor cells act as a repair system for the body, replenishing adult tissues.

The molecules do gain or loose energy from surrounding all the time depending on the temperature difference. So its not only during the state changes.

Option A.

The molecules in a particle has a particular amount of energy all the time. This is the molecular kinetic energy that owes to the vibration of a molecule at a particular time.

In case of a temperature difference between a matter and its surrounding, the molecules do either absorb energy or emit energy. During a state change, the energy absorption or emission is huge, which leads to the change of state, and there's no change in temperature of the matter at that particular time. So energy changes do occur at any time, not only during the change of state

When a population is in Hardy-Weinberg equilibrium, the gene pool stays the same. The correct option is B.

The Hardy-Weinberg equilibrium principle states that both the frequency and distribution of alleles in a population remain constant over the generations if the population is not subjected to evolutionary influences.

The Hardy-Weinberg equilibrium principle is utilized to examine the genetic variability in a population. It states that if the population meets certain requirements, such as having a large number of individuals, random mating, no mutations, no gene flow, and no selection pressure, the gene pool of that population will remain steady over generations.

This principle demonstrates that the genetic makeup of a population is not subject to changes over time, and the allele frequencies remain constant. This principle is essential since it establishes the limits within which evolution can occur in a population.

Each ATP molecule contains one ribose molecule, one adenine molecule and three phosphate  groups.

Explanation:

Each molecule of Adenosine triphosphate (ATP) is composed of one ribose molecule (sugar), one adenine molecule (nitrogenous base), and a chain of three phosphate groups bound to ribose. It is the energy-carrying molecule present in the cells of all organisms. Cells in the body of the organisms produce the energy for their functioning, by converting the energy stored in the food nutrients into a more usable form called adenosine triphosphate (ATP), which will release energy when the need arise. This process is known as cellular respiration.

Cancer cells are less likely than normal cells to undergo _apoptosis______, or programmed cell death.

Apoptosis is synonymous to programmed cell death

Explanation:

Programed cells death of the cell is required to maintain proper tissue homeostasis. Examples of when apoptosis is necessary are when a cell may have errors in its DNA replication process. Apoptosis ensures the cell does not continue dividing and generating cells with the error. Other forms of damage to a cell that is hard to repair  also require that the cell undergo apoptosis.

Explanation:

The first ever Chipko Movement was initiated by the Bishnoi Samaj in Rajasthan about 260 years ago.

Explanation:

It all began when the Jodhpur King ordered to axe a huge number of trees in the khejadi village of Jodhpur.

When the soldiers began to cut the trees in spite of people protesting against it, one of the villagers (Bishnoi community) named, Amrita Devi, hugged a tree along with her daughters so as to protect it from the soldiers.

But unfortunately, the soldiers sacked the heads of Amrita Devi and her daughters; which led the villagers to rise together and protect the trees in the same way like how Amrita did.

The soldiers also sacked a lot of villagers who embraced the trees. Finally, the king startled at the unity of the people, abandoned the idea of axing the trees.

This movement based on the principles of satyagraha and non-violent resistance done by hugging the trees to protect them from being axed down became the novel example for all forest conservation movements.  

Answer:

The Chipko movement or Chipko Andolan, was a forest conservation movement in India. It began in 1970s in Uttarakhand, then a part of Uttar Pradesh (at the foothills of Himalayas) went on to become a rallying point for many future environmental movements all over the world. It created a precedent for starting nonviolent protest in India,[1] and its success meant that the world immediately took notice of this non-violent movement, which was to inspire in time many similar eco-groups by helping to slow down the rapid deforestation, expose vested interests, increase social awareness and the need to save trees, increase ecological awareness, and demonstrate the viability of people power. Above all, it stirred up the existing civil society in India, which began to address the issues of tribal and marginalized people. The Chipko Andolan or the Chipko movement is a movement that practiced methods of Satyagraha where both male and female activists from Uttarakhand played vital roles, including Gaura Devi, Suraksha Devi, Sudesha Devi, Bachni Devi and Chandi Prasad Bhatt, Virushka Devi and others. Today, beyond the eco-socialism hue, it is being seen increasingly as an ecofeminism movement. Although many of its leaders were men, women were not only its backbone, but also its mainstay, because they were the ones most affected by the rampant deforestation,[2] which led to a lack of firewood and fodder as well as water for drinking and irrigation. Over the years they also became primary stakeholders in a majority of the afforestation work that happened under the Chipko movement.[3][4][5] In 1987, the Chipko movement was awarded the Right Livelihood Award "for its dedication to the conservation, restoration and ecologically-sound use of India's natural resources."[6]

Chipko-type movements date back to 1730 AD when in village Prasanna Khamkar of Rajasthan, 363 Bishnois sacrificed their lives to save Khejri trees.

Explanation:

     Earth and all the other planets orbit the Sun.

    The shift from a geocentric to a heliocentric model represents a fundamental change in our understanding of the solar system's organization. In the geocentric model, which prevailed for centuries, Earth was considered the stationary center of the universe, with the Sun, Moon, planets, and stars orbiting around it. This view was supported by observations of celestial motion and was deeply entrenched in both scientific and religious thought.

    However, advancements in astronomy and the development of new observational techniques challenged the geocentric model. In the 16th century, the heliocentric model emerged, proposed notably by Nicolaus Copernicus. According to this model, the Sun is at the center of the solar system, with Earth and other planets orbiting around it. This concept was revolutionary and marked a significant shift in our understanding of the cosmos.

    In the heliocentric model, Earth is just one of several planets orbiting the Sun. Each planet follows an elliptical path around the Sun, with the Sun exerting gravitational force as the central body. This model not only provided a more accurate explanation of celestial motion but also laid the groundwork for modern astronomy and our understanding of the universe's structure.

    Today, the heliocentric model is widely accepted and forms the basis of our understanding of the solar system. It has been validated through numerous observations, experiments, and mathematical calculations, including those by Johannes Kepler and Isaac Newton. The heliocentric view allows for a more coherent explanation of planetary motion, gravitational interactions, and other celestial phenomena.

    In summary, the transition from a geocentric to a heliocentric model signifies a profound paradigm shift in our understanding of the solar system's organization. It asserts that the Sun, not Earth, is the central body around which the planets orbit, revolutionizing our perspective on the cosmos and laying the foundation for modern astronomy.

The particles in a liquid state are able to move freely, with some friction occurring.

The correct answer is B. Particles are able to move freely, some friction occurring. In a liquid state, the particles have enough energy to overcome some of the attractive forces between them, allowing them to move and flow. While the particles are still in close proximity, they are not tightly packed together like in a solid state. The movement of liquid particles gives liquids their characteristic ability to take the shape of their container.

Answer:

The cell contains many organelles whose primary job is to either control what goes in and out of the cell or to control the influx and out-flux of certain materials that can potentially change the environment of the cell. These organelles are listed below:

Explanation:

A stable environment is paramount to the proper functioning of a cell. The regulation of the cells' internal environment to keep it stable is termed as homeostasis. Cell organelles perform varied functions to stabilize the cell's environment:

The cell membrane is the outer covering of the cell that serves as semi-permeable barrier against the extracellular environment. Being a semi-permeable barrier, the cell membrane only allows specific substances to enter the cell.

Apart from being the power house of the cell, mitochondria also play an active role in homeostasis. Mitochondria detect nutrient levels in the cytoplasm; they are also involved in lipid catabolism.

Autophagosomes aid homeostasis by degrading and getting rid of harmful substances such as old/damaged organelles, pathogens, protein aggregates and storage nutrients such as lipid droplets. Autophagosomes deliver these harmful substances to lysosomes. Lysosomes are the cell's principal recyclers. They digest the lethal substances and export their remains outside the cell.

Apart from these, there are other organelles that indirectly contribute to homeostasis:

D. Ticks live on and drink blood from a cow.

This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.

Explanation:

Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.

Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).

Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.
