Answer:
The correct answer is - true.
Explanation:
Most unsaturated fats are oils and normally are biological membranes or plant-based such as vegetables. These fats mostly have cis isomer in them. Unsaturated fats help to lower blood cholesterol levels.
However, few oils show saturated fats but these are few in number, the majority are made up of unsaturated fats that have double bonds.

during PROPHASE of MITOSIS?
Answer:
92 chromatids
Explanation:

The genetic code is defined degenerate or even redundant because:
A. the same codon codes for different amino acids
B. an amino acid can be encoded by several codons
C is different in all organisms, except in monozygotic twins
D. the sequence of codons is not separated by intervals, but is continuous
E. the structure of the genes is constantly mutating
Answer:
B. an amino acid can be encoded by several codons
Explanation:
The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.
Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.
For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer
Answer:
The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.
The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?
Answer:
Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.
The predominant forms of actin inside a cell are ATP-G-actin and ADP-F actin. What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin's ability to bind ATP
Answer:
If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.
Explanation:
As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.
At a birthday party, a teen decides to inhale some of the helium from a nearby balloon using his mouth. Before the helium gas reaches his right and left lungs, through which order of structures will it flow?
A. Oral cavity to the oropharynx to the trachea to the right and left main bronchi.
B. Oral cavity to the trachea to the trachea to the nasopharynx to the right and left main bronchi.
C. Oral cavity to the right and left main bronchi to the trachea to the oropharynx.
D. Oral cavity to the trachea to the larynx to the right and left main bronchi.
E. Oral cavity to the nasopharynx to the trachea to the right and left main bronchi.
Answer:
D. Oral cavity to the trachea to the larynx to the right and left main bronchi.
Explanation:
The respiratory system may be a system consisting of specific organs and structures used for gas exchange in animals and plants.
What is the process of respiration?We have a pair of external nostrils opening out above the upper lips. It results in a nasal chamber through the nasal passage. The nasal chamber opens into the pharynx, some of which are the common passage for food and air. The pharynx opens through the larynx region into the trachea.Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the extent of the 5th thoracic vertebra into a right and left primary bronchi. Each terminal bronchiole gives rise to a variety of very thin, irregular-walled, and vascularized bag-like structures called alveoli. The branching network of bronchi, bronchioles, and alveoli comprise the lung.
Thus, we can conclude that the correct option is (e).
The oral cavity to the nasopharynx to the trachea to the right and left main bronchi.

Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the
breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.
Which general function does lactase perform?
Answer:
Regulation of cell processes
Explanation:
Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.

A group of geologists is about to start excavating a new area for fossils. The area they are working in is the side of a cliff. Describe two pieces of information they will most likely be able to discover about the fossils they will find.
Answer:
Forms of fossils and there arrangement with layer of rock.
Explanation:
The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks. The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.I am stuck please help !!!!!!
Which of the cardiac cell characteristics describes the
ability to initiate an electrical impulse?
Answer:
The correct answer is: automaticity.
Explanation:
Cardiac muscle has several properties. These properties are: automaticity (given by the pacemaker cells), conductivity (meaning that each cardiac cell can transmit the electrical impulse to the next cardiac cells), contractility (like other types of muscles, cardiac muscle cells can contract), and irritability (each cell can contract on its own without the external stimuli).
Cardiac pacemaker cells are the ones with the capacity to initiate the electrical impulse by creating rhythmic impulses called action potentials, and thus directly regulating heart rate.
Pacemaker cells are located in the sinoatrial (SA) node, in the upper portion of the right atrial wall. In these cells, depolarization of the cardiac muscle begins, and the electrical impulse generated by it is transmitted to the atrioventricular (AV) node, the His bundle and then the Purkinje fibers - this order of events is necessary for the correct contraction of the heart to occur. All of these structures are part of the Conduction System of the heart.
