The small intestines are well adapted for absorbing nutrients during digestion by being very long, having villi and microvilli that increase surface area, using muscular contractions to move and mix food, and receiving and housing digestive enzymes and bile that help the breakdown of food.
The adaptations in which the small intestine make for absorption is the presence of a finger-like structure called villi.
What is Villi?These are finger-like structures found in the small intestine which increase the surface area for absorption.
They possess blood vessel which ensures the nutrients are transported to other parts of the body.

Which of these describes ATP?
A. the site of photosynthesis
B. genetic material
C. energy storage
D. cell waste
Answer:
C
Explanation:
ATP has to do with energy so the correct answer would be energy storage.
The one that describes ATP is energy storage. The correct option is C.
What is ATP?A chemical that is a part of all living cells and gives energy to a variety of metabolic processes, including the production of RNA.
In patients with advanced solid tumors, the effects of laboratory-produced ATP on weight loss and muscle strength are being investigated. Likewise known as adenosine triphosphate.
The principal energy source for critical biological processes such muscular contraction, nerve impulse transmission, and protein synthesis is ATP generated in mitochondria.
For example, large levels of ATP signal that the cell has enough ATP and does not need to produce any more through cellular respiration. In this instance, a product "feeds back" to block its pathway, which is a form of feedback inhibition.
Thus, the correct option is C.

Crabeater seals eat krill.
Fishermen catch large amounts of krill from the sea.
How would a decrease in the number of krill affect the number of
crabeater seals?
___________________________________________________________________
_____________________________________________
Leopard seals also eat krill.
A decrease in the number of krill will affect the crabeater seals sooner
than it affects leopard seals.
Give the reason for this.
if the number of individuals in the krill decreased, then the crab and crabeater seal populations would decrease because there would not be enough food for all of the individuals of their populations to eat.

Brad is swimming in the ocean on a hot sunny day. he finds the water to be much colder than the sand on the beach, even though the sun is warming them both. identify the reasons for brad’s observation. the water is colder than the sand because it requires more to change temperature. this is because the water has a higher than the sand.
Answer:
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up. The sand has a lower SHC so it requires less energy to heat up therefore heats faster and Brad will observe the sand to be hotter than the sea
The sea has a higher specific heat capacity than the sand meaning it takes more energy to heat up.
What do you mean by specific heat capacity?The specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/(kg K) or J/(kg °C).
In thermodynamics, the specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity.
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C. This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.

What are some possible benefits and dangers if the DNA is used to create a mutant form of the organism?
Explanation:
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Many other mutations have no effect on the organism because they are repaired beforeprotein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure below. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is likely to be prevented from dividing.
