Answer:
Every cell of their body contains defective , loss of function allele of a tumor suppressor gene
Explanation:
Tumor suppressor genes - They encode Proteins that inhibit cell proliferation . But due to Loss of functional alleles in Tumor suppressor genes it leads to the development of different cancers
Every cell of the body comprises of a defective and loss-of-function allele of a tumor suppressor gene.
The presence of defective and non-functioning tumor suppressor gene is responsible for the happening of cancer disease because the tumor suppressor gene slow down the process of cell division as well as repair mistakes occur in DNA molecule. When the tumor suppressor genes can't perform its function properly, it causes out of control growth of cell, which can lead to cancer disease so we can conclude that tumor suppressor gene is responsible for the cancer disease.

Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.

One Reason Why The Temperature needs To Be Kept Constant
Answer:
the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance
Explanation:
It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant. Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed

Please read the article Why Cats Have Nine Lives by Jared Diamond. Our analysis did not attempt to
answer the question of "Why" cats survive they way they do from different heights. What are some of
the assumptions the author makes that he uses in an attempt to answer this new question?
The author assumes that the question can be answered by applying principles of anatomy, physics and evolutionary biology. First reason he suggests is that cats are small and they have a favourable mass-surface area ratio. Next, he suggests that cats have soft tissues that absorb the shock and they land on all four limbs, dividing the shock. This is because of their body shape and its centre of gravity. He says that felines have this kind of body structure (that canines lack) because years of falling from trees etc. has evolved their body in this way.
The following assumptions that stem from the Straightforward theory were used by the author to explain why cats have nine lives. They include;
The larger mass of bigger animals causes more impact stress on landing.The unique vestibular systems of the cats and the gyroscopic turns they make that have their four feet pointing downwards before landing.The cats reach terminal velocity faster and extend their limbs reflexly to absorb the shock from the fall.The dissipation of the impact force due to their flexed limbs.Lastly, their evolutionary history that has seen them falling from trees frequently over the years.In his article, Jared Diamond profers several reasons why he believes that cats tend to suffer fewer injuries and fatalities after falling from different heights.
He believes that their mass which is lower in comparison to humans makes it possible for them to not suffer much impact force on landing.
The gyroscopic turns they make before landing makes it easier for them to land on their four feet thus suffering fewer injuries to the arms.
Their evolutionary history is another factor. Over the years, they have adapted so well to falling from heights.

Which of the following is true of mitosis? Select one: a. Mitosis is the cellular reproduction that occurs to form the sperm and the egg cells. b. Mitosis results in the formation of four new cells. c. Mitosis results in the formation of two new cells with 23 pairs of chromosomes. d. Mitosis results in the formation of three new cells.
Answer:
c. Mitosis results in the formation of two new cells with 23 pairs of chromosomes.
Explanation:
A and B are meiosis and D is wrong
The true statement about mitosis is that "Mitosis results in the formation of two new cells with 23 pairs of chromosomes"
WHAT IS MITOSIS:
Mitosis is the process of cellular division which produces two new daughter cells that each possess the same number of chromosomes as the parent cell. Mitosis is employed for growth and cellular repair in living organisms. In humans, mitosis results in two cells that possess 23 pairs of chromosomes each i.e. 46 chromosomes in each cell. Mitosis is opposed to meiosis in the sense that the latter produces four daughter cells with a reduced number of chromosomes.Therefore, the true statement about mitosis is that "Mitosis results in the formation of two new cells with 23 pairs of chromosomes".

A. Household garbage
B. Industrial waste
C. Leftover art supplies
D. Yard trimmings
The reuse center might accept: D. Yard trimmings
What is a reuse center?
A reuse center, also known as a recycling center or a second-hand store, is a facility where various materials and items that are still in usable condition are collected, sorted, and made available for resale or redistribution. The main goal of a reuse center is to divert materials from the waste stream and promote their reuse, extending their lifespan and reducing the demand for new products.
These centers typically accept a wide range of items, such as furniture, appliances, clothing, electronics, books, toys, and more. By accepting and selling these items at affordable prices, reuse centers help reduce waste, conserve resources, and provide affordable options for individuals and communities.
A reuse center can accept yard trimmings as it include grass clippings, leaves, branches, and other organic waste from landscaping and gardening activities.
