Which test would be used to determine if lipids are present?
a) iodine test
b) none of these are correct
c) Benedict’s test
d) emulsion test

Answers

Answer 1
The correct answer is the Emulsion test
Answer 2

Option d) emulsion test  would be utilized to determine if lipids exist present.

What is Emulsion test?

The emulsion test exists as a method to determine the existence of lipids using wet chemistry. The procedure exists for the sample to be suspended in ethanol, permitting lipids present to dissolve. The liquid exists and is then decanted into water.

This test is accomplished to demonstrate the presence of lipids in a substance. The substance exists first dissolved in ethanol. This solution exists then dissolved in water. If lipids exist present in the mixture, they will precipitate and create an emulsion.

Hence,Option d) emulsion test  would be utilized to determine if lipids exist present.

DNA is a nucleic acid involved in heredity, or the passing down of genetic traits from one generation to the next. DNA consists of four different types of nucleotide monomers.Which part of the nucleotides' structure is responsible for the incredible variation that exists amongst all types of organisms

Answers

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-Adenine is paired with Thymine (think of A for apple and T for tree)

-Cytosine is paired with Guanine (think of C for car and G for garage)

search "DNA base pairs" and go to images for better understanding

Explanation:

California Condors have been in decline about as long as European Settlements began to spread across North America. These birds have been on the U.S endangered species list since 1967 and were near extinction when their captive-breeding program began. California Condors also mature and reproduce slowly.

Part iii. What adaptations are associated with a frugivory diet? Give an example of a primate that has this diet.







Part iv. What adaptations are associated with a folivory diet? Give an example of a primate that has this diet.





Part v. What adaptations are associated with vertical clinging and leaping? Give an example of a primate that practices this form of locomotion.

Answers

The examples that you need are 1-Gummivory: marmoset, tamarins; 2-Frugivores: spider monkey, ray-bellied night monkey (owl monkey); 3-Folivory: howler monkey, leaf monkey, colobine; and 4-Vertical clinging and leaping: lemurs and tarsiers

A gummivore is an animal (in this case, a primate) with a feeding strategy that depends on the sap or gum from trees. It is a type of diet that consists primarily of exudates. Some adaptations observed in these species include: 1-specialized anterior teeth in order to stab bark; 2-well-developed claws for clinging to trees

Frugivores primates have a feeding strategy mainly based on raw fruits. Some adaptations observed in these species include 1-low rounded molar cusps and 2-broad incisors.

Folivore primates (also called leaf-eating monkeys) have a feeding strategy mainly based on leaves. Some adaptations observed in these species include 1-narrow incisors, 2-broad molars (high shearing crests), 3-thin enamel molars.

Vertical clinging and leaping is an arboreal locomotor pattern practiced by lemurs and tarsiers. These animals push off from one vertical support with their hindlimbs to land on another vertical support. Some adaptations observed in these species include 1-hips, knees, feet, arms, and tails that facilitate climbing and leaping, 2-large hip extensor muscles and 3-specialized minor muscles.

What is DNA replication?

Replication is the procedure by which the DNA of the genetic code is copied in cells.

Before dividing, a cell must duplicate (or replicate) its a whole genome so that each eventually results daughter cell has its own entire genome.

The DNA replicates itself multiple times during the process of replication. It is a biological polymerization that goes through the steps of commencement, elongation, and termination.

The reaction is catalyzed by enzymes. The main enzyme in the process of replication is DNA Polymerase.

DNA replication occurs in eukaryotic cells' interphase nuclei. At the S-stage (synthesizing) of the cell cycle, DNA replication occurs prior to mitosis.

Thus, the correct option is C.

Which of the following is an example of an enzymatic cycle?

Answers

Answer:

Catabolism

Explanation:

The process of catabolism degrades the bacterial and fungal enzymes into simple inorganic molecules.

A substance, without being a reactant, which speeds up a chemical process is referred to as a catalyst. Enzymes are known as catalysts for biological reactions in living organisms. Although ribonucleic acid (RNA) molecules behave as enzymes, they are usual proteins. Enzymes.

Enzymes carry out the essential role of reducing the activated energy of a reaction — that is, the amount of energy needed to start the process. Enzymes work by attaching and retaining reactant molecules so that the chemical bonding and bonding activities are carried out more easily.

Answers

Answer:

Describe the disadvantages of an open circulatory system relative to a closed circulatory system.

Answers

Explanation:

The disadvantage of a closed circulatory system is that with the blood always contained in vessels, it's under higher pressure. This means it can flow faster, which is necessary for supporting the metabolic rate of more complex animals such as vertebrates. Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism.

where are you choices

You are studying an enzyme that is inactivated by phosphorylation and create a mutant in which the threonine that is normally phosphorylated is replaced with glutamate. Predict the impact of this change on the activity of this enzyme. Group of answer choices

Answers

Answer:

always active  

Explanation:

Phosphorylation is a posttranslational modification that consists of the addition of phosphate groups to specific amino acids on the protein. Phosphorylation acts as a molecular switch for proteins that are phosphorylated (i.e., in some situations phosphorylation acts to activate protein function, whereas in other situations phosphorylation can inactivate protein function). Phosphorylation modifies the three-dimensional structure of the protein, thereby affecting, for example, the accessibility of the active site of a phosphorylated enzyme to its substrate. Phosphorylation can occur only at the side chains of three amino acids: Serine, Threonine and Tyrosine. In this case, the enzyme is inactivated by phosphorylation on the Threonine residue, so it is expected that the mutant enzyme cannot be phosphorylated, remaining in an active state.

Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is  an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells.
