why do our digestive systems produce separate enzymes to digest proteins, fats, and carbohydrates?

Answers

Answer:

The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.

Explanation:

Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.

There are different enzymes, produced in the digestive system, for this purpose:

Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.

The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

Which distribution pattern in species can be considered the most easily measurable

Answers

Answer:

local endemics

Explanation:

The most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

What is the significance of the geographical distribution?

It is significant because they differ in different parts of the world and provide suitable climatic and other environmental conditions for various animals, plants, and microorganisms to live and evolve. Its significance can be seen in the difference between the life forms in the temperate area and those in the Antarctic area.

Hence, the most common distribution pattern in species can be considered by their geographical distribution, as different species get distributed as per their climate and the different regions that suit them the most.

b. What does that mean for embryonic development for the animal phylum as compared to the animal phyla?

Answers

WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?

The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.

WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?

The embryonic development of animal phylum is also known as embryogenesis.

It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.

This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.

This embryonic development of animal phylum comprises of 36 animal phyla.

Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?.

Answers

Answer:

The bipedality

Explanation:

One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.

NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.

The knee ________.
a. is completely enclosed by a strong articular capsule
b. is a multiaxial joint
c. has ligaments present inside as well as surrounding the articular capsule
d. is the simplest joint in the body

Answers

Answer:

The correct answer is: C) has ligaments present inside as well as surrounding the articular capsule.

Explanation:

The knee joint is a hinge (ginglymus) type synovial joint that is formed by three different bones: the femur, the tibia, and the patella.

Given the nature of the hinge joint, it should only allow flexion and extension, but it also grants a small degree of internal and external rotation. For this reason, the knee joint cannot be considered a multiaxial joint, since it only fully moves in one axis and slightly moves in a second one (this is why most people consider the knee joint a uniaxial joint, but some others say it is actually a biaxial one).

The knee joint isn't completely enclosed by a strong articular capsule. The knee joint is rather thin and it contains the patella, menisci, bursae, and ligaments of the knee.

The knee is not the simplest joint in the body. It is formed by three bones and there's also the menisci, which are fibrocartilaginous structures that help increase the stability of the joint and act as shock absorbers as well.

The knee does have ligaments both inside and outside the articular capsule. The intracapsular ligaments are two cruciate ligaments (one anterior and one posterior), which hold the tibia in place; the transverse ligament that connects both menisci; and the posterior and anterior meniscofemoral ligaments. The extracapsular ligaments are the patellar ligaments (connects the patella to the tibia), the two collateral ligaments (medial and fibular, one on each side of the knee, connecting the femur to the tibia and to the fibula, respectively), and the anterolateral ligament.

How does the control group setup in an experimental differ from the other setups in the same experiment?

A control group setup in an experiment is used to see if there are other variables in play during the experiment. Say I was to test which type of blood is a shark's favorite, my control would be putting red paint in one of the set ups to see if the shark is just interested in the red color of blood, instead of the other types of blood.

Explanation:

Answer:

The control group does not receive the independent variable during the experiment.

Explanation:

The group that will receive the independent variable during the experiment is the experimental group. The dependent variable is what you will measure as a result. The control group is not receiving the independent variable during the group, as it is what you're measuring the experimental group to.

What are lipids?

Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.

Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.
