Answer:
The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Explanation:
the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.
This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.
Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air

How are cells and DNA related?
Answer:
The DNA never leaves the nucleus so it can't actually do the function of the cell. Instead, the DNA is like a blueprint made up of genes. The genes are read by the cell's nuclear machinery and produce specific proteins. Each gene codes for a specific protein.
Explanation:
A team of researchers has isolated a chemical from a tropical tree that causes insects to die when they ingest it. The researchers determine that the chemical deactivates the enzyme RNA polymerase. This chemical likely causes the insects to die by interfering directly with
Answer:
Transcription
Explanation:
Transcription is the first process of gene expression involving the synthesis of a mRNA molecule from a segment of DNA (gene). Transcription is key to the production of proteins, which bring about biochemical activities, in every living organism. The process of transcription is catalyzed by an enzyme called RNA polymerase.
According to the question that describes a chemical found to be produced by a tropical tree that kills insects. The chemical is discovered to deactivate RNA polymerase enzyme in the insect. This utterly means the chemical is interfering with the process of transcription of genes in the insect because transcription cannot occur without RNA polymerase.

What accounts for the differences in the properties of the various polysaccharides?
Answer:
Polysaccharides are present in all living organisms where they carry out one or more of their diverse functions. While there is no specific category or definition of a complex polysaccharide, most are structurally complex. Polysaccharides contain 1–5 different monosaccharide (sugar) units. The different sugar units may have different anomeric configurations and/or be joined by different glycosidic linkages. Polysaccharides may be linear or branched. Branches may be short saccharide units on a linear backbone or the molecule may have a branch-on-branch structure; in either case, the branches may be isolated or clustered. Polysaccharides may contain non‐carbohydrate groups. Esters or cyclic acetal groups, when present, can be removed by appropriate treatments. All polysaccharides are polydisperse, i. e., are present in a range of molecular weights rather than having a single molecular weight

10. Explain how the absorption of energy (heating) affects the speed of the particles in a substance.
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... When heat leaves all substances, the molecules vibrate slower.
The absorption of energy impact on the speed of the particles should be explained below.
Impact on the speed of the particles:In the case when the heat should be added to the substance so here the molecules and the atoms should be vibrate faster. Since the vibration of the atom should be faster so the space that arise between atoms should be increased. It measures the state of matter of the substance. However, when the heat left all kind of substance so the molecule vibrate the slower.

D. logos and cosmos because it was cut off in the pic NEED ANSWER HURRY
The correct answer is A. Ethos and Logos
Explanation:
The purpose of rhetoric is to use strategies to convince the audience. In the case of ethos, this relies on the reputation or prestige of individuals as this makes ideas to be credible. This technique is used in "a board-certified cardiologist with own twenty-five years of experience" because by mentioning the experience and profession of Dr. William Leu the author refers to his prestige and this would make the audience believe the findings of this doctor.
On the other hand, the use of logos implies the author uses logic or facts to explain an idea. This can be seen in "patients who eat whole foods and a diet low in sodium are 75 percent less likely" because the author uses percentages, which are derived from the use of logic and mathematics, and refers to proven facts.

Define these two categories of energy.
Renewable energy-
Non-renewable energy
Answer:
[See Below]
Explanation:
☆ Renewable Energy ☆
- This type of energy can't run out. It gets it's energy from the earth and so as long as the earth is intact it'll keep making energy. This includes Solar and Wind powered energy.
☆ Non-Renewable Energy ☆
- This type of energy comes from the earth as well, but it the more it's used, it can't be replaced as quick. This energy could be described as limited. This would include Gas, Oil, as well as Coal.

The bristle worm living with the hermit crab. Mutualism, commensalism, or parasitism
Answer: Mutualism
Explanation: The bristle worm removing parasites from the hermit crab and eating the hermit crabs leftovers
The bristle worm living with hermit crab is an example of mutualism. Thus, the correct option is A.
What is Mutualism?Mutualism describes the ecological interaction which is between two or more species where each of the species has a net benefit from the relationship. Mutualism is a common type of ecological interaction seen in the environment.
Plant-pollinator interactions are one of the good examples of mutualistic interactions because nearly about three-quarters of all the extant flowering plants, angiosperms receive pollination services from the animals called pollinators.
Therefore, the correct option is A.

What sequence of bases would pair with the DNA sequence TGAACTACCGAT?
Answer:
ACTTGATGGCTA
Explanation:
Keep this in mind:
Adenine → Thymine (A → T)
Thymine → Adenine (T → A)
Cytosine → Guanine (C → G)
Guanine → Cytosine (G → C)
Does this make sense? All you're doing is switching the letters out and replacing them with the corresponding one.
The DNA sequence is:
Adenine → Thymine (A → T)Thymine → Adenine (T → A)Cytosine → Guanine (C → G)Guanine → Cytosine (G → C)What is the DNA sequence in order?The sequence of the bases (regularly mentioned through the primary letters in their chemical names: A, T, C, and G) encodes the biological information that cells use to broaden and operate. Organizing the collection of DNA is prime for information on the feature of genes and different components of the genome.
Because there are four naturally going on nitrogenous bases, there are 4 one of a kind sorts of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Not all organisms have ______________________ like amoeba and parasites.
Answer:
Same characteristics.
Explanation:
Not all organisms have same characteristics like amoeba and parasites. Amoeba is a unicellular organism in which a single cell perform all necessary functions of life while many other organisms are multicellular in which different cells perform different functions in the body. Amoeba act as parasite because it cause disease in humans and take benefits from it but there are many beneficial organisms such as bacteria also present in human body which helps in digestion of food.

Afterwards, ______ is released form the motor endplate and the muscle ______ membrane depolarizes. ______ is released and binds to ______ resulting in the exposure of ______ binding sites. The ______ head binds and ______ splits ATP to ADP and inorganic phosphate. The final outcome is _______.
Answer:
The process of excitation-contraction coupling begins with the depolarization and subsequent excitation of a motor nerve. Afterwards, acetylcholine is released from the motor endplate and the muscle sarcolemma membrane depolarizes. Calcium is released and binds to troponin resulting in the exposure of actin binding sites. The myosin head binds and Myosin ATPase splits ATP to ADP and inorganic phosphate. The final outcome is muscle shortening.
Explanation:
The paragraph above summarizes the process of muscle contraction, which happens thanks to the release of acetylcholine in the neuromuscular junction, after the neuron is depolarized. The presence of acetylcholine will ultimately lead to the release of stored calcium so it can bind to a protein in the sarcomere called troponin. The binding of calcium and troponin will expose actin binding sites, making the binding of actin and myosin possible. The ATPase found in the myosin head will make use of ATP to produce the movement of myosin - this is how muscle contraction happens.
Lung cancer cells do not respond to the signals that regulate the growth of normal lung cells. Which of the following processes is NOT appropriately regulated in the cancerous cells?
Answer:
The correct answer is : mitosis.
Explanation:
Malignant growth or cancer is basically an abnormality of mitosis - the ordinary 'checkpoints' directing mitosis are ignored by the tumor cell. Disease starts when a single cell is altered, or changed over from an ordinary cell to a malignant growth cell.
Mitosis is firmly constrained by the qualities inside each cell. If genes did not control or perform their work properly occurs in only a single cell, it can reproduce itself to make new cells that are likewise uncontrollable and leads to tumor or cancer.
