Why do scientists think that cuttlefish
have the biggest brain to body ratio of all
invertebrates (animals without a spine)?
Answer:
Due to its high intelligence.
Explanation:
Scientists think that cuttlefish have the biggest brain to body ratio of all invertebrates that allows it to sense sight, smell, and sound that comes to it in the form of pressure waves. Due to this big brain, cuttlefish are very intelligent so due to its intelligence the scientists thinks that cuttlefish has the biggest brain as compared to other big vertebrates such as octopus.

Answer:
Star A
Explanation:
If you look directly at the diagram, the dwarf stars are labeled under 'A' and are the least in mass and temperature.
Being the smallest and coldest, dwarf stars most commonly have red coloration, which would make them the obvious choice.
Star A which is a dwarf star has the coldest temperature, and therefore is a red star since red stars are the coldest stars.
What are stars?Stars are a large self-luminous bodies whichbpriducw large amounts of heat energy and light energy as a result of the nuclear reactions occurring within them.
Stars have different colors and different sizes.
Red stars are the coldest stars and also the least massive.
From the chart, Star A which is a dwarf star has the coldest temperature, and therefore is a red star.

What are the three main classifications that describe galaxies? By what one visible
characteristic do scientists categorize galaxies?
Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.

biological macromolecules are organized into four main categories. What type of macromolecule contains phosphorus as part of a phosphate group?
1.) lipids
2.) proteins
3.) nucleic acid
4.) carbohydrates
Answer:
3.) nucleic acid
Explanation:
Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).
Biological macromolecules are organized into four main categories and these includes;
I. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.
II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.
III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.
IV. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.
Hence, the type of macromolecule that contains phosphorus as part of a phosphate group (sugar 2-deoxyribose) is nucleic acid.
From the biological macromolecules, Nucleic acids contains phosphorus as part of a phosphate group.
Nucleic acids are biopolymers, macromolecules, crucial for all known types of life. Nucleotides, which are the monomer components, make up their structure. a sugar with five carbons, a phosphate group, and a base with nitrogen. Deoxyribonucleic acid and ribonucleic acid are the two main types of nucleic acids.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two types of nucleic acids that carry genetic information that is read by cells to create the RNA and proteins that allow living things to function.

which statement describes what happens with ATP during glycolysis?
A) more ATP is produced than is used
B) glycolysis splits ATP
C) more ATP is used than is produced
D) glycolysis does not make any ATP
Answer:
A. more ATP is produced than used
Explanation:
Regulation of glycolysis
Several steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK). This reaction is the first committed step, making PFK a central target for regulation of the glycolysis pathway as a whole^1
1
start superscript, 1, end superscript.
PFK is regulated by ATP, an ADP derivative called AMP, and citrate, as well as some other molecules we won't discuss here.
ATP. ATP is a negative regulator of PFK, which makes sense: if there is already plenty of ATP in the cell, glycolysis does not need to make more.
AMP. Adenosine monophosphate (AMP) is a positive regulator of PFK. When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP \rightarrow→right arrow ATP + AMP). High levels of AMP mean that the cell is starved for energy, and that glycolysis must run quickly to replenish ATP^2

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits
Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
Hence, the correct option is C.

A. carnivores
B. trophic levels
C. heterotrophs
D. herbivores
Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.
What do you mean by herbivores?A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.
Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.
Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.

What happens to excess carbohydrates in animals?
They are stored as fat.
They are stored as protein.
They are stored in nucleic acids.
They are stored as sugar.
Answer:
A-They are stored as fat.
Explanation:
In animals, the excess of carbohydrates or glucose is first converted into glycogen (polysaccharide) through the process called glycogenesis. ... When glycogen reservoirs are saturated, excess carbohydrates, as well as proteins, are converted into fats which are then majorly stored in adipose tissues.
Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults
