Answer:
protect the cell from invading phages
Explanation:
The natural role of the restriction enzymes is to protect the cell from invading phages.
The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.
Once a phage invades a bacterium, the restriction enzyme quickly acts by cutting the phage's DNA into smaller pieces, leading to the destruction of the DNA and hence, the protection of the bacterium cell.

a. what process is occurring in the plant's cells to produce the gas in the bubbles that appear?
b. what gas is the plant producing?
c. what source of energy is the plant using to conduct the process recorded in part a?
Answer:
a. Photosynthesis
b. Oxygen
c. Light from the lamp
Explanation:
a. The process that is occurring in the plant's cell to produce the gas in the bubble is photosynthesis. The process involves the use of inorganic substances such as carbon dioxide and water in the presence of light to manufacture carbohydrates. Oxygen is evolved in the process. The equation for the process is as below:
[tex]6 CO_2 + 6 H_2O + light --> C_6H_1_2O_6 + 6 O_2[/tex]
b. The gas produced by the plant is oxygen as shown in the equation above.
c. The source of energy the plant is using to conduct the process is the light from the lamp. Light catalyzes the excitation of photosystems, causing the release of electrons that causes the splitting of water.
what is stomata plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz give me the answer
Answer:
Actually i attended Bilology classes two decades ago. But i still remember that stomata is the outer lining of plants' leaves through which exchange of gas takes place with the surrounding environment.
Answer:
are tiny openings
Explanation:
Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Answer:molecular biology: examination of life at the level of atoms and compounds
Explanation:
Molecular biology deals with the study of living things at molecules level
this is what controls them and make them up.
Molecular biology is a branch of biochemistry that deals with molecules which are specifically connected to living processes.
molecular biology requires the genetic material of an organism which is the nucleic acids (Deoxyribonucleic acid and Ribonucleic acid) and the proteins that are formed using the genetic instructions encoded in those molecules.

a measure of the pull of gravity on an object
the speed at which an object strikes Earth
the distance between an object and Earth
Answer:
Weight is a measure of the pull of gravity on an object.
Explanation:
The easiest way the justify this answer is the fact that your weight is different when your on the moon then when your on earth because there is less of a gravitational force on the moon.

A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. What is the total distance the toy car traveled? 1 cm 5 cm 11 cm 19 cm
Answer:
19 cm
Explanation:
The total distance traveled by the toy cay would be 19 cm.
The total distance traveled should not be mistaken for total displacement. While displacement measures the distance and direction from the starting position of the toy car relative to its final position, the total distance traveled is calculated by adding all the movements of the toy car together. Hence;
Total distance traveled = 9 + 4 + 6 = 19 cm
The total distance the toy car traveled is 19cm
Distance measures how far a body or an object has moved no matter the direction has taken (either positive or negative)
For the toy car that is placed at 0 on a number line, the toy moved the following distance:
9 cm to the left4 cm to the right6 cm to the left.Total distance = Total distances to the left + total distance to the right
Total distance = 9cm + 6cm + 4cm
Total distance = 19cm
Hence the total distance the toy car traveled is 19cm

How did the “Father of Anatomy” contribute to the study of the human body?
Answer:
Andreas Vesalius became first to study human anatomy.
Explanation:
Andreas Vesalius wrote a book called Seven Chapters on the Structure of the Human Body that caused to the rise of advanced human anatomy. His work became very notable for medicine because it gave physicians a thorough knowledge of human anatomy, and it propelled them to examine the claims of ancient medical experts, which were unusual than Vesalius hypotheses. He's seen as a Renaissance figure of the 16th Century and considered being the father of modern medicine.

Carbon dioxide is A a toxic gas produced by landfills. B produced by plants during photosynthesis. C needed by industry to power generators. D a greenhouse gas that traps heat in the atmosphere.
Answer:
The correct answer is option D, that is, a greenhouse gas that traps heat in the atmosphere.
Explanation:
A natural phenomenon in which the atmospheric gases captivates heat and permits Earth to retain enough solar energy to be livable is termed as the greenhouse effect. The greenhouse gases are the methane, carbon dioxide, nitrous oxide, and other gases, which gathers in the atmosphere and produces a heat-reflective layer that helps in trapping sunlight and keeps the Earth warm.
Of these greenhouse gases, carbon dioxide is the largest contributor to climate change. It is largely emitted at the time of burning fossil fuels like natural gas, oil, and other carbon-rich sources. Due to this, the level of carbon dioxide increases in the atmosphere resulting in the global phenomenon termed global warming.

This is one of the stages of Cell division in organism cells.it is marked with the the separation of homologous chromosomes into separate sister chromatids by the mitotic spindles.
other phases of cell division are -Interphase,Prophase, Metaphase,Anaphase and Telophase_ IPMAT
Based on mechanisms these sister chromatids are formed by the breaking down of the special protein : Cohesin which holds the sister chromatids together.As this protein is broken down, each chromatids moves to the opposite poles of the cells.
Generally there are two types of cell division,mitosis and meiosis. Anaphase it divided into 1 and 11 in meiosis, but made up of single phase in mitosis.
The separations of the identical chromatids into separate cells ensures that variation can occur,It also prevent fusion or non- disjunction of the chromosomes,which may lead to abnormalities.

What part of the body reproduces, grows, repairs itself, uses oxygen and nutrients, digests food, eliminates waste, produces heat and energy, and is able to move around
Answer:
A Human Cell
Explanation:
A Human Cell can do many things. All your organs, hair, skin, and muscle tissue are all made up of cells. Each human cell from a different part of your body can do and create different things. For example, the cells duplicate (which is reproduction), when it duplicates, it grows. It also uses the oxygen and nutrients for cellular respiration, when it takes in the oxygen and nutrients, it turns it into ATP, which is used to help your cells function. There are many other ways the human cell may relate to the question above. But here are some of the ways a human cell can be all those things.
