In relation with carbohydrate absorption the correct statement is- maltose is transported through the portal vein to the liver.
The correct option is c.
Complex carbohydrates are first broken down into oligosaccharides by stomach and salivary enzymes, which are subsequently hydrolyzed to monosaccharides by particular disaccharidases situated at the enterocyte brush boundary.
The small intestine is where carbohydrates are chemically broken down instead of the stomach. The disaccharidases and pancreatic amylase complete the chemical cleavage of digestible carbs. The liver receives the monosaccharides once they are absorbed into the circulation.
Dietary lactose, sucrose, and maltose—all of which are sugars—diffuse in the small intestinal lumen and come into contact with the absorptive epithelial cells that line the villi. There, they interact with brush border hydrolases, which break down the sugars into two molecules of glucose by the enzyme maltase.
The complete question is:
Which of the following is incorrect concerning carbohydrate absorption? multiple choice
a. end products of carbohydrate digestion are transported through the portal vein to the liver.
b. disaccharides are digested to monosaccharides by enzymes that are attached to intestinal cells.
c. maltose is transported through the portal vein to the liver.

Blood is called tissue give reason
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similarly specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
Explanation:Blood is considered a type of connective tissue because it connects the body systems, transports oxygen and nutrients to all the parts of the body, and removes waste products. Blood has an extra-cellular matrix called plasma, with red blood cells, white blood cells, and platelets floating in it. Blood is a specialized form of fluid connective tissue. Blood is regarded as a connective tissue because as the blood is circulated throughout the body due to the pumping action of the heart, it carries different materials and gases from one part of the body to another. Hence, it connects different tissues and organs of the body and thus, is called connective tissue. It is considered a connective tissue because it consists of blood cells surrounded by a nonliving fluid matrix called blood plasma. It is the most atypical connective tissue: the fibres of blood are soluble protein molecules that become visible during blood clotting.
studies of rough-skinned newts have documented their ability to produce toxins in defense against a predator attack. the common garter snake, a predator of rough-skinned newts, exhibits a resistance to the toxin produced by the newt. in response, newts have been observed to produce increasingly potent toxins, which in turn results in selection for snakes with even greater resistance to the toxin. what phrase best describes this interaction between rough-skinned newts and garter snakes? group of answer choices host-parasite coevolution obligate mutualism evolutionary arms race diffuse coevolution
Evolutionary arms race best describes the interaction between rough-skinned newts which have the ability to produce toxins against their predator garter snakes.
What is an evolutionary arms race?
It is an ongoing struggle between competing sets of co-evolving genes, and phenotypic and behavioral traits that develop escalating adaptations and counter-adaptations against each other.
One example is the arms race between bats and moths. In this, the weaponry used by each is largely based on sound and hearing.
In the above case, rough-skinned newts are compared to the host and the common garter snake is compared to a parasite. Rough-skinned newts produce toxins in defense against a predator (common garter snake). This predator exhibits resistance to the toxin produced by the newt. in this way, if the newt increased potent toxins then a common garter snake too increases its resistance to the toxin. Common garter snakes exhibit an evolutionary arms race by evolving rough-skinned newts.
Let us discuss other options
Mutualism is a relationship between two organisms each benefiting from the relationship.Host-parasite coevolution is a special case of coevolution where a host and a parasite continually adapt to each other.Diffuse coevolution also called guild coevolution where whole groups of species interact with other groups of species leading to changes that cannot really be identified.Hence rough-skinned newts and common garter snakes exhibit an evolutionary arms race.

When attempting to locate something under the microscope, the objective lens that should be started with is 4X.
Objective lens are the one that are placed closest to the specimen when observing under the microscope. Their function is to gather light from the specimen and focus it towards a different type of lens called the ocular lens.
4X is the lowest magnification of the objective lenses. However, they have a larger field of view and therefore more of the specimen can be observed at once that allows the observer to locate the exact target. Due to poor magnification, the target may not be clearly visible, however it can be later watched in higher magnification.

The light exposed test tubes will become colorless while dark test tubes will remain blue.
During the light reaction, the photolysis of water occurs. The breakdown releases hydrogen ion and electrons which are further used for reduction of NADP. The reduced NADPH contributes to the ATP generation.
Now, DCPIP also accepts the electron. So, during the light reaction in test tube exposed to light, the photolysis of water will occur followed by reduction of DCPIP. Thus, it will become colourless. Dark test tube wil not have the same reaction and hence DCPIP will remain blue in colour.

Tang is no less important part of the anatomy of the nervous system is the nerve cell itself or called a neuron. The function of a nerve cell or neuron is to transmit nerve impulses.
Based on their function, neurons are divided into three types, namely sensory neurons that carry messages to the central nervous system, motor neurons that carry messages from the central nervous system, and interneurons that transmit messages between sensory and motor neurons in the central nervous system.
Each neuron or nerve cell consists of three parts or basic structures. The anatomy of these neurons, namely:
- The cell body, which has a nucleus.
- Dendrites, which are shaped like branches and function to receive stimuli and carry impulses to the cell body.
- The axon is the part of the nerve cell that carries impulses away from the cell body. Axons are generally surrounded by myelin, which is a dense, fatty layer that protects nerves and helps messages pass. In peripheral nerves, this myelin is produced by Schwann cells.
