Answer: chemical reactions
Explanation: The function of an enzyme is to speed up chemical reactions. They do this by lowering the activation energy, which is the minimum energy that must be available for a chemical reaction to occur. If the energy required is lowered, the reaction can go faster.
what are cotyledons? & what is its use
Answer:
Cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

only one variable.
O C. His conclusion is flawed because he did
not perform enough trials.
O D. His conclusion is flawed because it is
based on the appearance of the plants.

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.

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.

Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for the same phenomenon. B. Natural selection is an outdated theory to explain how evolution took place. C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce. D. Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.

• Genes are used as a set of instructions to produce proteins.
Proteins affect the
and function of organisms.
Chromosome
Answer:
- DNA is wrapped around nucleosomes and condensed into chromosomes.
- Proteins affect the traits and function of organisms.
Explanation:
Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.
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.

Answer:
True
Explanation:
An individual who exhibits a mixture of schizophrenic symptoms most likely has undifferentiated schizophrenia.
The most likely diagnosis for someone who displays a variety of schizophrenic symptoms is undifferentiated schizophrenia. The aforementioned is therefore True.
What is schizophrenia?The illness that impairs a person's capacity for clear thinking, feeling, and behaviour is schizophrenia. Although the precise origin of schizophrenia is unknown, it is thought that a mix of genetics, environment, and changes in brain chemistry and organization may be at play.
Schizophrenia is characterized as disorganised speech or behaviour, depressed participation in daily tasks, and ideas or experiences that appear disconnected from reality. Memory loss and attention problems could also be present.
Therapy is typically ongoing and frequently consists of a mix of prescription drugs, psychotherapy, and well-coordinated specialty care services.

3. Which of the following statements best explains how the cell membrane 1 point
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.
