Gregor Mendel and Australian monk who lived in the 1800s is known as the father of genetics explain why Mendel has given this title.
Gregor Mendel, an Austrian monk who lived in the 1800's, is known as the father of genetics. Explain why Mendel has been given this title. He was the first person to explain the mechanisms of heredity because of his experiments with pea plants.
Gregor Mendel is deemed the father of genetics due to his groundbreaking research in heredity using pea plants, which led to fundamental principles of genetic inheritance.
Explanation:Johann Gregor Mendel is known as the father of genetics because of his pioneering work with pea plants which laid the groundwork for our understanding of genetic inheritance. Conducting experiments in the garden of his monastery, Mendel painstakingly crossed pea plants and observed the inheritance patterns over multiple generations. His discovery of dominant and recessive traits, along with the concept that traits are passed down independently, revolutionized the biological sciences. Mendel's research ultimately led to the laws of inheritance that bear his name, Mendel's Laws, which explain how traits are transmitted from parents to offspring.

A student was observing slides of cell division in one of the slides he noticed loosely coiled chromatin depicting DNA replication which phase of the cell cycle could it be
Interphase as it prepares cell for division by occurrence of some important biological functions and duplicate genetic material (DNA)
Answer:
DNA replication occurs during the S phase.
Explanation:
During the processes of the cell cycle is a phase called the S phase (Synthesis Phase) in which the DNA is replicated, occurring between the two phases G1 and G2.
Complete accurate DNA instructions in the cell must be duplicated in order to produce two similar daughter cells which occurs during the S phase where loosely coiled chromatin can be seen.
Which of the following statements about Earth’s energy budget are true?
a. Most energy reaches Earth from space as visible light.
b. Most of the energy that leaves Earth travels in the form of visible light.
c. More than 99% of Earth’s outgoing energy comes from energy brought to Earth’s surface in volcanic eruptions.
d. Energy leaves Earth’s system only during the daytime
e. The thermal energy (heat) that you feel when you put your hand on the ground originates from the sun.
Answer: E. The thermal energy (heat) that you feel when you put your hand on the ground originates from the sun.
Explanation:
Most energy reaching Earth is visible light from the Sun and thermal energy from the ground originates from the Sun as it's absorbed and emitted as heat, options (a) and (e) are correct.
Most energy reaching Earth is in the form of visible light from the Sun. The Sun's nuclear fusion processes primarily produce energy in the form of visible light, which then travels through space and reaches Earth. This visible light is what makes our planet habitable by providing the energy necessary for photosynthesis in plants and warming the Earth's surface.
The thermal energy (heat) you feel when touching the ground also originates from the Sun. Solar energy is absorbed by Earth's surface, warming it. This heat is then conducted into the ground and radiated back as thermal infrared radiation. This process maintains the Earth's temperature and sustains life on our planet. So, the warmth you experience when touching the ground is ultimately a result of the Sun's energy input into Earth's system, options (a) and (e) are correct.

Compare and contrast the processes of mitosis and meiosis.
Part A. Describe two processes that occur in both mitosis and meiosis.
Part B. Think about the cells at the outcome of both processes. How are they different? Explain at least two differences.
Part A:
1. Both the processes of meiosis and mitosis are the kinds of cell division in which one cell forms or produces more than one cell, that is, both follow duplications of chromosomes.
2. Both the procedures include dissociation of the nuclear membrane, and both require spindle fibers to move the chromosomes around.
Part B:
1. Mitosis comprises one stage while meiosis comprises two stages. Mitosis produces diploid cells, while on the other hand, meiosis generates haploid cells.
2. Mitosis gives rise to two similar daughter cells, while meiosis gives rise to four genetically similar daughter cells.

Answer:
According to cell theory, all organism arise from the pre existing cell. Cell acts as the structural and functional unit of the living organism. Viruses may be defined as the organism that contain DNA and RNA as their genetic material. Viruses are smaller than bacteria and can affect the different forms of life.
Viruses are non-living as well as acellular organism because they cannot perform the metabolic process that are performed by the living organism. They acts as non - living organism as they do not reproduce, show growth and metabolism outside the host environment. They only shows growth and reproduction once they enter inside the host organism.

Velma is developing a computer model of translation. Her instructor points out that the model does not include ribosomes or ribosomal RNA. If the model is accurate in other ways, how does the absence of ribosomes and ribosomal RNA affect it? A. Certain amino acids would be missing from the polypeptides.
B. The polypeptides would be much longer than normal.
C. Amino acids would be joined together in an incorrect order.
D. Amino acids would not join together, and no polypeptides would form.
The correct answer would be option D.
Ribosomal RNA or ribosomes are the site if protein synthesis in a cell.
The small and large subunits of the ribosome form a complex around the initiation codon of mRNA.
The ribosome also has a peptidyl transferase activity which helps in adding amino acid to growing polypeptide chain.
Thus, in absence of ribosome no polypeptide chain would form.

The “push” needed to start a chemical reaction is the:
enzymatic energy.
endothermic energy.
activation energy.
reactant energy.
its reactant energy, hope this helps :)
The “push” needed to start a chemical reaction is the activation energy. Option C is correct.
Activation energy is the minimum amount of energy that is required for a chemical reaction to start. It is the energy barrier that the reactants must overcome in order to form products. Without activation energy, the reactants would not have enough energy to break their bonds and form new ones. This is why chemical reactions do not happen spontaneously.
Enzymes are biological molecules that can help to lower the activation energy of a chemical reaction. This means that enzymes can make reactions happen faster by providing the necessary energy boost. Endothermic energy is the energy that is absorbed by a system during a chemical reaction. Reactant energy is the energy that is possessed by the reactants before a chemical reaction takes place. Option C is correct.

What is the difference between a population showing exponential growth and a population showing logistic growth? (Site 1)
Population growth refers to the patterns governing how the number of individuals in a given population changes over time. These are determined by two basic factors: the birth rate and death rate.
Answer:
A population can show two types of growth, exponential or logistic. Exponential growth occurs in case of unlimited resources like unlimited food or space. Organisms in the population do not have to compete with each other and the population can grow indefinitely. Such a growth model shows J shaped curve when population size is measured against time.
Logistic growth occurs in case of limited resources and competition. The population has carrying capacity i.e. maximum number of individuals it can hold before the population growth becomes stagnant. This model shows S shaped curve when population size is measured against time.
In real life logistic growth is shown by populations. Exponential growth is not possible since the resources get used up after some time.

how did world war 2 change marine science
When soldiers would go into underwater vessels they would see different species that we didn't know existed. After the war, scientists started researching these creatures.
World War II facilitated advances in marine science through the development of technologies for submarine detection, which post-war contributed to the growth of oceanography departments, national labs, and the acceptance of seafloor spreading.
World War II significantly altered the course of marine science by stimulating the development of technologies that were later pivotal in studying the ocean depths and understanding geological phenomena like seafloor spreading. The urgent military need to detect submarines led to advancements in oceanic research, resulting in expanded studies and an enhanced understanding of the ocean's properties. These developments fueled the growth of oceanography as a science, with the establishment of oceanography departments at universities and the founding of national ocean laboratories. The technologies forged in this crucible of war—ranging from sonar to deeper-diving submarines—provided researchers after the war with new tools to explore and comprehend the planet's underwater landscape, ultimately contributing to the acceptance of theories like plate tectonics.
Which mutation in a fruit fly could be passed on its offspring?
(1) a mutation in a cell of an eye that changes the color of the eye
(2) a mutation in a leg cell that causes the leg to be shorter
(3) a mutation in a sperm fell that changes the shape of the wing
(4) a mutation in a cell of the digestive tract that produces a different enzyme
note ; please explain why your answer is correct
Only mutations in reproductive cells can be inherited. Therefore, a mutation in a sperm cell that changes the shape of the wing is the one that could be passed on to the offspring.
Mutations in fruit flies can affect various traits, but not all mutations can be passed on to the next generation. The key to determining which mutation can be inherited lies in understanding the difference between somatic cells and germ cells. Somatic cells make up most of the body and include cells in the eyes, legs, and digestive tract, as mentioned in the options provided. In contrast, germ cells are the reproductive cells (sperm and eggs) that are involved in passing genetic information to offspring.
Out of the given options, only the mutation in a sperm cell that changes the shape of the wing (option 3) can be passed on to the offspring. This is because sperm cells contribute to the formation of the next generation, and any mutations they carry can be inherited if they lead to fertilization. Mutations in somatic cells such as those in the eyes, legs, or digestive tract (options 1, 2, and 4) are not passed on to offspring because they do not affect the germ line.
