Answer: Carcinogens
Explanation:
Carcinoids refer to a specific type of slow growing tumor, tumors are the cancerous growths within a body, and sarcomas are tumors that occur in bones and soft tissues.
Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
where are the masses and velocities of the objects 1 and 2 respectively before collision.
Hence, the object will move at 30 m/s
From prophase through metaphase of mitosis, each chromosome has 2 DNA molecule(s), while from anaphase through telophase of mitosis, each chromosome has one DNA molecule.
Explanation:
Mitosis is a process in which 2 identical daughter cells are formed in which DNA gets split into two sets of chromosome.
Mitosis occurs in four phases: Prophase, metaphase, Anaphase and Telophase.
After the G2 phase the DNA amount increases and get ready for the division here sister chromatid are seen not chromosome.
In metaphase the chromosome align at the equatorial plate and readied to separate the sister chromatids easily. Each chromatid contains 1 DNA molecule, in this phase two sister chromatids are there so 2 molecules of DNA are present.
In Anaphase the sister chromatids are pulled towards the opposite ends. Each cell receives one chromatid which is now 2 chromosmes. So one chromatid will have one DNA molecule.

Answer:
Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Astigmatism can be corrected with glasses, contact lenses, or refractive surgery (i.e. laser eye surgery), although treatment may not be necessary if the symptoms are mild. Glasses and contact lenses both compensate for the irregular shape of the cornea and help to focus light properly into the back of the eye
