As compared to the circulatory system of most fishes, the circulatory system of adult amphibians has the advantage of a single circuit. partially-separate circuits for gas exchange and systemic delivery of blood. complete separation between oxygenated and deoxygenated blood. a four-chambered heart. a pocket of the gut that serves as an air bladder.
Answer:
Partially separate circuits for gas exchange and systemic delivery of blood.
Explanation:
Adult amphibians have separate circuits for gas exchange and systemic delivery of blood. Fishes usually breathe through gills and very few have nostrils. The fishes can breathe underwater with the help of their gills.
A population of birds can have large, heavy beaks or thin, long beaks.
What can we say based on this data?
Select one:
We cannot conclude anything without having more data.
Having heavier beaks is a survival advantage.
Having longer beaks is a slight survival advantage, but having more data would help to confirm.
undo
There is no survival advantage between having heavier beaks and longer beaks.
Answer:
We cannot conclude anything without having more data.
Explanation:
All the statement says it that the birds have different types of beaks. There is no mention of information that the beak difference brings advantage or not. If the question were to say the heavy beaks survive more, then the answer would be those birds have an advantage- because it does not, the answer is we need more data
Which of the following cell membranes is the most fluid?
Membrane A, because it is composed of saturated fatty acids that have one or more cis bonds that form stable aggregations
Membrane A, because it is composed of saturated fatty acids that lack weak hydrogen bonds that continually break and reform to permit macromolecule movement
Membrane B, because is it composed of unsaturated fatty acids that form weak covalent bonds at the site of their cis bonds, which permit easy movement
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing
Answer:
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing.

Which of the following species is Endemic?
A. Geese on the East coast of the US
B. African elephants at the zoo
C. Invading Japanese beetles found eating crops in North American farms
D. Lemurs isolated to the island of Madagascar
Answer:
D. Lemurs isolated to the island of Madagascar
Explanation:
Endemic is to be native and restricted to a certain place.
Endemic species are organisms that are limited and confined to a particular region. Lemurs show endemism as they are isolated to the island of Madagascar. Thus, option D is correct.
What is Endemism?Endemism is a biological term used to depict the distribution of the organism in an area that becomes its habitat. It is shown by species that are limited and bounded to one geographical location.
Endemism is shown by the species due to genetic isolation that separates the population or the species in a geographical area and does not allow the genetic material to exchange by reproduction.
Koalas and Kangaroos in Australia, Lemurs in Madagascar, lion-tail macaque and Nilgiri blue Robin in India, and camellia plant in Japan are some endemic species.
Therefore, option D. the Lemurs in Madagascar are an example of endemic species.

Answer:
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself
Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.

please help me out, name all 3 parts of the atom.
In the atom, the arrow 1 depicts the proton. The arrow 2 depicts the neutrons, and the arrow 3 depicts the electrons. All three of these are subatomic particles.
What is an atom?An atom is the fundamental structural unit of matter. It consists of protons, neutrons, and electrons. Electrons are negatively charged particles that are present outermost shell of the atom, while protons are positively charged particles that make up the core of the atom. The neutron doesn't have any charge.
Both neutrons and protons make up the core of an atom, while electrons revolve around them. A neutral atom has equal numbers of protons and electrons. Example: the sodium atom.
Hence, the atom showing arrow 1 is a proton, arrow 2 is a neutron, and arrow 3 is an electron.

The consensus is that the coelacanths and lungfishes (Sarcopterygii) represent an evolutionary link between ray-finned fishes and tetrapods. What is the major feature in the Sarcopterygii that supports this hypothesis?
Answer:
Choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares.
Explanation:
Sarcopterygii also known as lobe-finned fishes which usually possess a choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares are present internally. The lungfishes are considered the closest living relatives of tetrapods because of the presence of some common features. The African lungfish has epithelial crypts located at the base of the lamellae of the olfactory epithelium that express markers of the vomeronasal receptors in tetrapods.

Answer:
(a)The strength of natural fibers is very less as compared to synthetic fibers. Natural fibers are heavy in weight. Natural fibers can be damaged by moths and other insects. These fibers are not wrinkle-free. These fibers are not long lasting and hence not durable.
(b) Cellulose is termed as polymer because it is made up of many monomer units.
(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.
(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.
(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.
(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

Determine whether the following statement is true or false. If false, select the choice that will make it true. "Aerobic respiration produces Glucose."
A. True
B. False, it produces proteins.
C. False, it breaks ATP into ADP.
D. False, it produces ATP.
Answer:
D. False, it produces ATP
The statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP. Thus, the correct option is D.
What is Aerobic respiration?Aerobic respiration may be defined as a chemical process in which oxygen is utilized in order to construct energy from carbon dioxide and water. This type of respiration typically takes place in the presence of oxygen to catalyze a given set of reactions.
Aerobic respiration occurs in presence of water. It takes place with help of glucose further convert into pyruvate to derive carbon dioxide, water, and energy in form of ATP. The process of aerobic respiration is also known as oxidative metabolism and cell respiration. In this process, glucose reacts with oxygen to form ATP.
Therefore, the statement "Aerobic respiration produces Glucose" is false. This is because it produces ATP along with carbon dioxide and water. Thus, the correct option is D.
