(7)What did Von Roelliker discover?
(8)What did Virchow add to the development of the cell theory?
(9)Describe Pasteur’s experiments and the observations he made.
(10)What do all living things have?
Answer:
1.
1) All living organisms are composed of one or more cells.
2)The cell is the basic unit of structure and organisation in organisms.
3) Cells arise from pre-existing cells.
2. The first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
3. law of elasticity (Hooke's law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory
4. His discovery of the nucleus and its role helped to put together the cell theory, which states that all living organisms are composed of cells, and cells come from pre-existing cells.
5. He published his findings and called the process he saw “binary fission”. He concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter.
6. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory.
7. that the sperm and egg were composed of cells and that humans are formed of cells from beginning to end.
8. In 1855, he further developed his ideas by publishing his famous aphorism omnis cellula e cellula which became a part of the foundation for cell theory. Virchow's theory stated that just as animals are unable to arise without previously existing animals, cells are unable to arise without previously existing cells.
9. Pasteur's experiment showed that microbes cannot arise from nonliving materials under the conditions that existed on Earth during his lifetime. The experiment had to do with Pasteur adding nutrient broth to flasks, bent the necks of the flasks into S shapes, and then boiled the broth to kill any existing microbes.
10. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.

What is the end result of meiosis? four identical daughter cells four different daughter cells two identical daughter cells two different daughter cells
Answer:
B. Four Different Daughter Cells
Explanation:
The end result of meiosis results in the production of four genetically different daughter cells.
The result of meiosis is four different daughter cells.
• A kind of cell division, which minimizes the number of chromosomes in the parent cell by half and generates four gamete cells is known as meiosis.
• This process is needed to generate sperm and egg cells for sexual reproduction.
• Meiosis starts with a parent cell, which is diploid, that is, it has two copies of each chromosome.
• The parent cell goes through one round of replication of DNA succeeded by two distinct cycles of nuclear division.
• In the end, four haploid daughter cells are produced, that is, they contain half the number of chromosomes present in the parent cell.
Thus, four different daughter cells are produced at the end of meiosis.

What do you think happens to the particles of air inside the ball as it warms in the sun?
There is matter inside the balloon. The mixture of gas present in the balloon is a form of matter which has some kinetic energy which will increase with the increase in temperature.
What is Kinetic energy?Kinetic energy is the energy present inside a body which is in motion. Here, the molecules of gas present inside the balloon possess kinetic energy. The kinetic energy of all the gases is almost similar at a specific temperature regardless of their constituents.
The kinetic energy of gas present inside the balloon increases with the increase in the temperature. When the balloon is kept in the sun, due to the heat of Sun, kinetic energy of gas particles inside the balloon also increases and the balloon expands. This will lead to an increase in the pressure on the walls of the balloon.

Summary
Answer:
Explanation:
question 1
the resulting imbalance between incoming solar radiation also outgoing thermal radiation most likely causes the earth to heat up over the next 10 years.
question 2
much like a conveyor belt, transporting warm water and precipitation from the equator making the cold water from the poled back to tropics
question 3
greenhouse gasses trap more and more energy from the sun, oceans are absorbing the heat at a slower rate.
question 4
climate change due to human activity had a direct impact on marine species
1. Solar radiation drives climate by influencing temperature and weather patterns.
2. Ocean currents distribute heat, affecting regional climate and weather conditions.
3. Climate change causes sea-level rise, ocean acidification, altered currents, and disrupted coastlines.
4. Climate change harms marine biodiversity through temperature shifts, acidification, and habitat disruption.
1. Solar radiation plays a crucial role in driving Earth's climate system. It determines the amount of energy that reaches the Earth's surface, influencing temperature patterns, atmospheric circulation, and the formation of weather systems. Changes in solar radiation can directly impact climate, leading to variations in temperature and weather patterns.
2. Ocean currents have a significant influence on climate. They distribute heat from the tropics to higher latitudes, affecting regional temperature patterns. For example, the Gulf Stream carries warm water from the tropics to the North Atlantic, moderating temperatures in Western Europe. Changes in ocean currents can lead to shifts in climate patterns and weather conditions.
3. Climate change has profound effects on the ocean. Rising temperatures cause thermal expansion, contributing to sea-level rise. Increased carbon dioxide emissions also lead to ocean acidification, which negatively impacts marine ecosystems and organisms like coral reefs and shellfish. Climate change can disrupt ocean circulation and alter precipitation patterns, affecting ocean currents and coastal areas.
4. Climate change poses significant threats to marine biodiversity. Rising sea temperatures and ocean acidification harm marine species, particularly those reliant on specific temperature and pH conditions. Coral bleaching events, driven by climate change, can devastate coral reef ecosystems. Changes in climate can also disrupt food chains and habitats, leading to biodiversity loss in marine ecosystems.

Gene therapy has been used to treat and cure cystic fibrosis. Cystic fibrosis is caused by a _________ in a single gene?
Answer:
mutation
Explanation:
trust me, i took the test
Gene therapy has been used to treat and cure cystic fibrosis. Cystic fibrosis is caused by a mutation in a single gene.
What are mutations?A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Moreover, hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life. These are called sporadic, spontaneous, or new mutations. They affect only some cells.
Therefore, mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

The Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body.
What is connective tissue?
All other types of tissues in the body are supported by connective tissue, which joins or divides them. Like all tissue types, it is made up of cells encased in a space of liquid known as the extracellular matrix (ECM).
In contrast to other forms, connective tissue's cells are loosely rather than densely packed within the ECM.
The three components of connective tissue are cells, ground substance and fibers. Ground substance and fibers make up the extracellular matrix (ECM).
The primary cell of connective tissue is the fibroblast. Its function is to produce and maintain the ECM of connective tissue. Besides fibroblasts, several other cell types are present.
Therefore, The Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body.
