    The tallest animal on earth is... - ProProfs

    The tallest animal on earth is...

    • Ostrich

    • Giraffe

    • Kangaroo

    • Dinosaurs

    Correct Answer
    A. Giraffe
    Explanation
    The giraffe is the tallest animal on earth, with males reaching heights of up to 18 feet. Their long necks and legs allow them to reach leaves high up in trees. Ostriches are the largest birds but not the tallest animals overall. Kangaroos are marsupials and are known for their powerful hind legs, but they are not as tall as giraffes. Dinosaurs were a diverse group of reptiles that lived millions of years ago, and while some may have been tall, giraffes are the tallest animals currently living on earth.

    Origin of species was written by... - ProProfs

    Origin of species was written by...

    • Charles Babbage

    • Charles Darwin

    • Charleston

    • John Locke

    Correct Answer
    A. Charles Darwin
    Explanation
    "Origin of Species" is a renowned scientific work that introduced the theory of evolution and natural selection. It was written by Charles Darwin, a British naturalist, in 1859. Darwin's groundbreaking ideas challenged the prevailing beliefs about the creation and diversity of species, and his book became a cornerstone of modern biology. Charles Babbage was a mathematician and inventor known for his work on early computers, while Charleston is a city in the United States. John Locke was a philosopher and political theorist, but he did not write "Origin of Species."

    Living things that make their own food are.. - ProProfs

    Living things that make their own food are..

    • Autotrophs

    • Heterotrophs

    • Omnivorous

    • None of the following

    Correct Answer
    A. Autotrophs
    Explanation
    Autotrophs are living organisms that are capable of producing their own food through photosynthesis or chemosynthesis. They convert energy from sunlight or inorganic compounds into organic molecules, such as glucose, which they use as a source of energy. Examples of autotrophs include plants, algae, and some bacteria. Heterotrophs, on the other hand, cannot produce their own food and rely on consuming other organisms for energy. Omnivorous refers to organisms that consume both plants and animals. Therefore, the correct answer is Autotrophs.

    What is the study of structure and functions? - ProProfs

    What is the study of structure and functions?

    • Physiotherapy

    • Physiology

    • Physics

    • Phoroston

    Correct Answer
    A. Physiology
    Explanation
    Physiology is the study of the structure and functions of living organisms. It focuses on how different parts of the body work together to maintain homeostasis and perform various biological processes. This field of study helps us understand the mechanisms behind bodily functions and how they are regulated. It is an essential discipline in the medical and biological sciences, providing insights into the functioning of the human body and other organisms.

    The basic unit of hereditary is... - ProProfs

    The basic unit of hereditary is...

    • Cell

    • Chromosome

    • Genes

    • Chloroplast

    Correct Answer
    A. Genes
    Explanation
    Genes are the basic units of heredity. They are segments of DNA that contain instructions for building and maintaining an organism. Genes determine the traits and characteristics of an individual, such as eye color, height, and susceptibility to certain diseases. They are passed down from parents to offspring and play a crucial role in inheritance and evolution. Genes are found in the chromosomes within the nucleus of a cell.

    The basic unit of life is... - ProProfs

    The basic unit of life is...

    • DNA

    • Genetics

    • Cells

    • Chromosomes

    Correct Answer
    A. Cells
    Explanation
    Cells are the basic unit of life because they are the smallest structural and functional units that can carry out all the necessary processes for life. Cells are responsible for carrying out essential functions such as growth, reproduction, metabolism, and response to stimuli. They are the building blocks of all living organisms and can exist as single-celled organisms or as part of multicellular organisms. DNA, genetics, and chromosomes are all important components within cells, but cells themselves are the fundamental units that make up all living things.

    Which Organelle does photosynthesis take place? - ProProfs

    Which Organelle does photosynthesis take place?

    • Chloroform

    • Chlorophyll

    • Chloroplast

    • Photomorph

    Correct Answer
    A. Chloroplast
    Explanation
    Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells. Chloroplasts contain a pigment called chlorophyll, which absorbs sunlight and uses it to drive the chemical reactions of photosynthesis. Therefore, the correct answer is chloroplast.

    Exobiology is... - ProProfs

    Exobiology is...

    • The study of life in the soil

    • The study of life in outer space.

    • The study of life in water

    • The study of life in the other life

    Correct Answer
    A. The study of life in outer space.
    Explanation
    Exobiology is the study of life in outer space. This field of science focuses on the search for and study of extraterrestrial life, including microorganisms and potential intelligent beings, beyond Earth. It involves examining the conditions necessary for life to exist on other planets, moons, or celestial bodies, as well as investigating the possibility of life originating elsewhere in the universe. Exobiologists utilize various scientific disciplines, such as astronomy, biology, chemistry, and physics, to explore the potential for life beyond our planet.

    Who was the first to talk about theory of mutation. - ProProfs

    Who was the first to talk about theory of mutation.

    • Charles Darwin

    • Hugo Se Vries

    • Jan David

    • Charles Babbage

    Correct Answer
    A. Hugo Se Vries
    Explanation
    Hugo de Vries was the first to talk about the theory of mutation. He was a Dutch botanist who proposed the concept of mutation as a driving force for evolution. De Vries conducted extensive research on plant breeding and observed sudden variations in plant traits, which he attributed to mutations. His work on the theory of mutation, published in his book "The Mutation Theory," challenged some aspects of Charles Darwin's theory of evolution by natural selection. De Vries' contribution to the understanding of genetic variation and mutation laid the foundation for modern genetics.
