The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.
Answer:
4
Explanation:
The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection according to Darwin's (and Wallace's) theory of evolution.
Natural selectionNatural selection is the process through which populations of living organisms adapt and change.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation.Thus, we can conclude that The diversity of life on our planet comes from the process of evolution supported by the mechanism of natural selection.

Bryophytes is the answer :)
Explanation:
If some bacteria are resistant to tetracycline and some are not resistant, what happens when a patient is given tetracycline for an infection?
Answer:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

which type of specialized cells would be found in an animal’s neuvous system?
The type of specialized cells would be found in an animal’s nervous system are the cells that transmit signals around the body. The correct option is D.
What is the nervous system?The nervous system is the part of an animal's body that controls behavior and sends messages to other parts of the body. It is divided into two components in vertebrates: the central nervous system (CNS) and the peripheral nervous system. The CNS houses the brain and the spinal cord.
Neurons are specialized cells found in animals. These cells are classified as sensory neurons, interneurons, or motor neurons based on their function. They transmit signals from the body to the brain and from the brain to the body parts.
Therefore, the correct option is D. Cells that can transmit signals around the body.

is selectively permeable? *
The movement of specific substances into and out of the cell is controlled by the cell
membrane
The movement of waste substances into, but not out of the cell is controlled by the
cell membrane
The cell membrane is inflexible and cannot control the movement of substances into
and out of the cell
The cell membrane does not surround the cell so it plays no role in the movement of
substances
Answer:
The movement of specific substances into and out of the cell is controlled by the cell membrane.
Explanation:
The cell membrane is permeable, so it allows for the passage of substances both into and out of the cell. It is also selective, so only specific substances can enter and exit the cell.

The drawback or disadvantage associated with the use of light microscopes over electron microscope is its lower magnification power.
LIGHT MICROSCOPE:
Light microscope is a type of microscope in which photons of light is used to view specimens. The light microscope is distinct from the electron microscope being that electron microscope uses beam of electrons instead. One advantage of light microscope is that it can view specimens alive while electron microscope can only view dead specimens. However, one disadvantage associated with the use of light microscope is that it possesses a lower magnification compared to electron microscopes.Learn more at: https://brainly.com/question/4442916

have a good day :)
Explanation:
when are chromosomes (dna) copied?
Answer:
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.
Have a good day. :)
Answer:
Chromosome replication
Explanation:
Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

brainliest?Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories
Answer:
D. 367
Explanation:
If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.
What is food energy?Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.
The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
To find the total calories, multiply the given biomolecules grams with their calorie count.
= 42 × 4 + 7 × 9 + 34 × 4
= 168 + 63 + 136
= 367 calories
Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.
