Answer:
The correct answer is -
1. photosynthesis and cellular respiration
2. glucose and cellular respiration
3. O2
4. C6H12O6
5. CO2
6. H2O
Explanation:
For the survival and growth of a plant, there are several functions and structure are essential but two most important parts are photosynthesis that provides food and glucose for the plant and its nourishment and other is cellular respiration which is required to convert glucose into ATP a form of energy.
In animals, photosynthesis is not possible so they depend on the plants and other sources for glucose and another important process for growth and survival is cellular respiration.
The chemical formula of oxygen, glucose, carbon dioxide, and water is as follow:
3. O2 - oxygen
4. C6H12O6 - glucose
5. CO2 - carbon dioxide
6. H2O - water

DNA is called a DOUBLE helix. Why would the structure of DNA
be referred to as double? (hint: number of strands, or sides?)
PLEASE HELP
Answer:
The model is called a double helix because two long strands twist around each other like a twisted ladder. The rails of the ladder are made of alternating sugar and phosphate molecules. The steps of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.

4. It controls or regulates the body's internal brain environment, including the body temperature, pulse and respiration rate, and bood pressure. e. autonomic nervous system
5. It is one of the systems that is directly involved in maintaining the normal functions of cells. d. nervous system
Explanation:
Neuron: Neurons are the structural and functional units in the nervous system. Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.
Peripheral nervous system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.
Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.
Autonomic nervous system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.
The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.

Cite particularly the difference in the synthesis of the two biomolecules in animals and plants.
Answer:
The preceding section reviewed the major metabolic reactions by which the cell obtains and stores energy in the form of ATP. This metabolic energy is then used to accomplish various tasks, including the synthesis of macromolecules and other cell constituents. Thus, energy derived from the breakdown of organic molecules (catabolism) is used to drive the synthesis of other required components of the cell. Most catabolic pathways involve the oxidation of organic molecules coupled to the generation of both energy (ATP) and reducing power (NADH). In contrast, biosynthetic (anabolic) pathways generally involve the use of both ATP and reducing power (usually in the form of NADPH) for the production of new organic compounds. One major biosynthetic pathway, the synthesis of carbohydrates from CO2 and H2O during the dark reactions of photosynthesis, was discussed in the preceding section. Additional pathways leading to the biosynthesis of major cellular constituents (carbohydrates, lipids, proteins, and nucleic acids) are reviewed in the sections that follow.
Go to:
Carbohydrates
In addition to being obtained directly from food or generated by photosynthesis, glucose can be synthesized from other organic molecules. In animal cells, glucose synthesis (gluconeogenesis) usually starts with lactate (produced by anaerobic glycolysis), amino acids (derived from the breakdown of proteins), or glycerol (produced by the breakdown of lipids). Plants (but not animals) are also able to synthesize glucose from fatty acids—a process that is particularly important during the germination of seeds, when energy stored as fats must be converted to carbohydrates to support growth of the plant. In both animal and plant cells, simple sugars are polymerized and stored as polysaccharides.
Gluconeogenesis involves the conversion of pyruvate to glucose—essentially the reverse of glycolysis. However, as discussed earlier, the glycolytic conversion of glucose to pyruvate is an energy-yielding pathway, generating two molecules each of ATP and NADH. Although some reactions of glycolysis are readily reversible, others will proceed only in the direction of glucose breakdown, because they are associated with a large decrease in free energy. These energetically favorable reactions of glycolysis are bypassed during gluconeogenesis by other reactions (catalyzed by different enzymes) that are coupled to the expenditure of ATP and NADH in order to drive them in the direction of glucose synthesis. Overall, the generation of glucose from two molecules of pyruvate requires four molecules of ATP, two of GTP, and two of NADH. This process is considerably more costly than the simple reversal of glycolysis (which would require two molecules of ATP and two of NADH), illustrating the additional energy required to drive the pathway in the direction of biosynthesis.

5. According to a biomass pyramid, 50 mice will need 200 square meters of grass, if one mouse needs to eat four square meters of
grass to stay healthy.
O false
true
I will give out brainliest
Answer:
The statement is true.
Explanation:
As every single living organism, the mice also have their own unique requirements as to how much food they need to produce enough energy in order to stay healthy. Because the mice are small, warm-blooded, highly active, and have very fast metabolisms, they need a lot of food for their size.
If one mouse needs four square meters of grass to stay healthy, so if we want to find out how much grass is needed for more mice we just need to multiply the number of mice by the amount of grass needed for one mice. In this case, we have 50 mice:
4 x 50 = 200
We got 200 square meters of grass, meaning that that would be the amount/area of grass that will be enough to support the population of 50 mice.
If your nose is completely clogged and you try to blow it out, you are generating pressure from your lungs. a. The smaller your nasal passage, the less force the pressure from your lungs will exert on the clog. b. The smaller your nasal passage the more force your pressure will exert on the clog. c. The size of the nasal passage does not affect the force your lungs exert on the clog.
Answer:
The correct answer is - option A. The smaller your nasal passage, the less force the pressure from your lungs will exert on the clog
Explanation:
Velocity depends on the area of the passage and directly affected by this as velocity is inversely proportional to the area of the passage, therefore, the lesser the nasal passage area higher will be the velocity.
v=Q/A
By this it is clear that the required pressure will be less and velocity will be more and less pressure generated from the lungs.
The correct answer is - option A.

10. Which type of telescope is known to be difficult to keep aligned?
rotating
refracting
reflecting
radio
Explanation:
Larger lenses are heavier, and tend to sag under their own weight, ruining the image quality as the lenses distort. The long mounting tubes are hard to make mechanically stiff, and so they tend to flex under the weight of the lens, making it hard to keep the optics in alignment.
The different types of telescopes include refracting telescopes, reflecting telescopes, radio telescopes, and rotating telescopes.
The refracting telescope was used by Galileo to discover the mountains and valleys on the moon.These refracting telescopes required long lenses in order for the light to focus properly.However, these long lenses made the telescope heavy.Because of their heaviness, it becomes difficult to keep refracting telescopes aligned.Hence, the correct answer is refracting telescopes.

what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems
Answer:
Expected outcome: HH, Hh, Hh, and hh
The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem
Explanation:
This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).
According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:
HH, Hh, Hh, and hh
3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).
Answer:
75% hairy stems; 25% hairless stems
Explanation:
14. a science student claims that a substitution mutation is less likely to affect gene function than an insertion or deletion mutation. use logical reasoning and evaluate this claim.
Because insertions and deletions produce a frame-shift that modifies the interpretation of following codons, they are frequently more detrimental than substitutions that modify only one amino acid.
What is a mutation?A alteration in the DNA sequence of an organism is referred to as a mutation. Errors in the replication of DNA during the process of cell division, exposure to mutagens, or viral infections are all potential causes of mutations.
Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.
Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, as a result, alters the entire amino acid sequence that follows the mutation, insertions and deletions are typically more harmful than substitutions, in which only one amino acid is changed. This is because frame-shifts change the reading of subsequent codons.
