There is a lot of talk about gaps in the fossil record. This means that we do not necessarily have fossils for every organism that has ever lived. What do you think could account for these gaps in the fossil record?
Answer:
Explanation:
The rate decomposition of dead remains, to a large extent, determines whether there would be fossils left of the organism after it has been long gone or become extinct. Environmental factors (such as harsh weather condition and early insect invasion of dead remains) could increase the rate of decomposition of dead remains which could really make it difficult for fossils to be available for such organisms under these factors (especially if the organism is restricted to a particular region by nature) .
There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in all types of eukaryotic cells?
A. chloroplast
B. cell wall
C. nucleus
D. centrioles
Answer:
nucleus
Explanation:
chloroplasts and cell walls are only found in plant (and fungi) cells, while centrioles are only in animal cells.
The structure that is found in all types of eukaryotic cells is the nucleus. The correct option is C.
What are eukaryotic cells?Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.
There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.
The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.
Thus, the correct option is C. nucleus.

The _______________ rate describes the rate at which the atmosphere gets colder as the air gets thinner at higher altitudes.
Answer:
Lapse rate
Explanation:
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

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
A)Enzymes do not affect the energy of a reaction.
B)Enzymes slow down reactions so products can form.
C)Enzymes can be reused because they do not permanently bond with substrate.
D)Enzymes can only bind to other enzymes so the same product is formed each time.
Answer: C
Explanation: Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Enzymes can be reused because they do not permanently bond with substrate.
What are Enzymes?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Therefore, Enzymes can be reused because they do not permanently bond with substrate.

Answer:
Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

Why do the cells used for reproduction only have half (½) of the DNA that other cells have?
Answer:
Because each chromosome has a pair, these cells are called "diploid" cells. On the other hand, human sperm and egg cells have only 23 chromosomes, or half the chromosomes of a diploid cell.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.
Answer:
No, because he used different soils.
Explanation:
which liquid will cause bean plants to grow faster.
He watered the plants with equal amounts of liquid and measured their height every other day.
The plants are in the same pots with different soils and placed in the same location.
Ok so last statement made the experiment wrong.
As a constant variable the soil should be the same for all plants only the liquid should change

If the food on the island is small seeds, what finch is best adapted? Explain why
Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.
