What is the expected result when the end product of a metabolic pathway binds to an enzyme in that pathway?
Answer:
Feedback inhibition.
Explanation:
It is feedback inhibition pathway because it is a cellular control process in metabolic part wat in which the output of a metabolic pathway binds to an enzyme at the regulatory sites which is distinct from the active sites of the substrates, causing a conformational changes on the enzyme which then makes it to slow down or inhibit it's production or synthesis.
This help to prevents excess of the high levels of the product from accumulating in the cell
Which complex carbohydrate contains only a-1,4-glycosidic linkages?
Answer: Amylose
Explanation: Which complex carbohydrate contains only a-1,4-glycosidic linkages? Amylose (Amylose is formed from a-1,4-glycosidic linkages of glucose.)
Amylose has α 1 ⟶ 4 α glycosidic linkage, besides this carbohydrate, all other carbohydrates have β 1 ⟶ 4 glycosidic linkages.
What is a Glycosidic bond?A Glycosidic bond is the type of linkage that occurs between two or more sugar molecules. It is formed between the hemiacetal or hemiketal group of one saccharide and the hydroxyl group of another saccharide.
The compound has a glycosidic bond known as a glycoside.
Two types of glycosidic bonds are observed such as 1,4 alpha and 1,4 beta glycosidic bonds.
The 1,4 alpha glycosidic bond is named when the OH on the carbon-1 is below the glucose ring, while the 1,4 beta glycosidic bond is formed when the OH is above the plane of a glucose ring.
Amylose has been the compound that contains only alpha 1, 4 glycosidic linkages.

How are carrying capacity, ecosystems, and biodiversity interrelated with one another?
Help pleasee!!!
The ecosystem, biodiversity, and carrying capacity are interrelated as everything is related to the living diversity present in an ecosystem.
What is an ecosystem?An ecosystem is a group of living things that communicate with one another. It is the geographic area that contains plants, animals, and other biotic and abiotic factors.
The quantity of biodiversity that can be sustained in a region is known as its carrying capacity. An ecosystem is a group of living things that communicate with one another. The biodiversity of plant and animal species is known as its biodiversity.
A space's carrying capacity reveals how long and how much of an ecosystem it can support, which in turn reveals how much biodiversity is possible.
Thus, because everything is connected to the living diversity present in an ecosystem, the ecology, biodiversity, and carrying capacity are all interconnected.

a. reproduce more slowly than primary consumers
b. are larger than primary consumers
c. are smaller than tertiary consumers
d. could be more regerred to as "carnivoires"
e. are more numerous than primary consumers
Answer:
e
Explanation:
The correct answer would be that they are more numerous than primary consumers.
Secondary consumers are never more numerous than primary consumers. This is primarily due to the fact that the higher we move up the food chain, the less efficient the amount of energy derived from food. Up to 90% of energy is sometimes lost at each trophic level as we up. Due to this inefficiency, the available food at top consumer levels can only support a few organisms. Hence, the higher we move up the food chain, the lesser the number of organisms the available food can support.

Veronica got a cut on her arm, and it started bleeding. Her circulatory system started working hard to prevent blood loss and protect against infection. Which two components of the blood were functioning at a higher level than normal? platelets and plasma plasma and red blood cells white blood cells and platelets red blood cells and white blood cells
According to the question, the two components of the blood that were functioning at a higher level than normal are white Blood Cells and platelets. Thus, the correct option is C.
What are the components of blood?The components of blood may generally include red blood cells, white blood cells, plasma, and platelets. Blood generally performs the function of transporting oxygen and nutrients throughout the body.
While these components play specific roles in making the conditions suitable for an individual's survival. For example, platelets cluster together to form a clot and prevent bleeding at the site of an injury.
While red blood cells govern the function of hemoglobin, white blood cells are involved in fighting infectious diseases. They are also known as the soldiers of the body.
Therefore, the two components of the blood that were functioning at a higher level than normal are white Blood Cells and platelets. Thus, the correct option is C.
