Answer:
a) specialized structures and organs for reproduction (flowers)
b) lignin in the xylem
c) waxy cuticle, stomata
Explanation:
a) Angiosperms have flowers, which are specialized reproductive organs. Flowers contain specialized reproductive cells (i.e., pollen cells) which can be dispersed by wind or animals.
b) Plant tissues can be covered by a waxy cuticle that helps to conserve water and tiny pores called 'stomata' in the epidermis that close in order to prevent water loss.
c) Finally, the xylem in land plants provides mechanical support. The cell walls of the xylem are composed of lignin, an organic substance that provides structural rigidity to the plant fibers.
Answer:
A) The absence of an aquatic environment for reproduction.
Pollination. Flowers are developed in order to reproduce, flowers help by attracting animals to pollinate (pollination aids). Pollen for males, seed for females. The seeds are coated with a hard outer layer to protect it. Fruits are made so animals can it them and the seeds will spread by the means of their feces. Seeds can be dormant for a long time.
B) The absence of an aquatic environment to support the plant body.
Roots to help hold to the ground, stems for support, vascular tissue to help hold shape, cell walls more rigid, turgor pressure.
C) Dehydration of the plant.
The cuticle was developed, a waxy outer layer found in the leaves to prevent water from leaving the plant. Stomates control water movement, in trees scales and cork help keep water in. Xylem transports water.

Explanation:
Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydrates in living organisms. The most important carbohydrate is glucose that is metabolized by all living cells in the first energy-yielding pathway known as glycolysis.
Use your knowledge of glucose for carbohydrate metabolism to select the term that best completes each sentence.
The glucose conversion to_________ opens anaerobic and aerobic metabolic pathways. ________in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the The TCA cycle. converts lactate to glucose and returns the glucose molecule to the muscles through
In the Cori cycle, the release of energy from_________ the process of anaerobic glycolysis.
Answer:
The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.
Explanation:
In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).
In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.
The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.
VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.
In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

For each of the following minerals, say what properties of the material make it important in carrying out it's particular function.
a. tar roads
b. iron bulgar bars
c. plastic furniture
d. metal jewellery
e. clay for building
f. cotton clothing
Answer:
1. Tar Roads: The qualities of Tar that makes it ideal for road construction are:
The tar-like material that is used for road construction is a combination (emulsion) of water and liquid asphalt. It serves the purpose of permeating and closing up small lacerations in the existing pavement.
When the emulsion sticks to the "gravel" it reduces the potential for vehicles to skid on the road thus enhancing safety. The "gravel-like" emulsion is applied by rolling and sweeping.
Qualities of Tar are:
Adhesive: its the ability to stick to surfaces including materials such as gravel which it holds together makes it great for road construction;Waterproof: It is not water-soluble. Hence is not easily susceptible to the effects of running water. Resistant to High Temperature: The melting point of Tar is 54 degrees centigrade. The ground can heat up to 45 degrees celsius thus making Tar perfect for road construction as it can remain rigid even in the worst temperatures.2. Iron Burglar Bars
Steel bars are made from iron. The qualities of steel which make it perfect for securing places and things are:
Strength; This is the ability to withstand breakage and or destruction. Toughness: Steel is very tough and can not easily bend or break under static loads. Weldability: Most steel bars are actually welded together. Without this ability, steel probably would be useless as a material that can be used for protectionDurability: The only factor that degrades steel is rust. Rust happens when steel is exposed to oxygen which can be found in air and water.3.) Plastic Furniture
The primary qualities of plastic that make them suitable for furniture are:
Chemical stability: It does not rust or degrade when exposed to weather elements such as oxygen, water, etc. Good impact resistance: Depending on its thickness, plastic can bear a lot of weight and can take a lot of impact without deforming or breaking Good transparency and wear resistance: Plastic can be made transparent. This quality is essential for aesthetic purposes and hence can be used for various kinds of good-looking furniture. As furniture, its surface does not come off like hence it's durability.Low thermal conductivity: This means that it can bear heat without transmitting it easily. Ability to General formability, good coloring, low processing cost.4) Metal Jewellery
One of the best metals for jewelery is Tungsten. This is so because it is more durable and stronger than any other kind of material that can be used for jewelery purposes. It is about ten times harder than 18K gold and about four times harder than titanium. Other materials that can be used are:
titaniumstainless steel and cobalt5) Clay
In it's raw form, clay used for building might not be the best idea as it susceptible to water absorption and hence deformation which generally leads to a collapse of the structure. However, it becomes an excellent material of choice after it has been hardened into brick.
Brick is preferred in construction due to the following qualities:
hardnessHigh Compressive strength, Low Water AbsorptionFrost resistanceFireproofGreat Insulation6) Cotton is usually preferred as the material of choice for most kinds of clothing due to the following qualities:
Softness. The cotton plant is soft and fluffy and results in a fabric often retains that soft feel. Durability: Its molecular structure makes it able to last very long. Absorbency: it is able to absorb moisture/water. Hence making it more comfortable than synthetic materials High Dye Tolerance: Ability to hold dye well is an indespensable quality of a good fabric. You don't want to have a fabric whose colours are quick to fade. Breathability: This reduces is very important especially during summer or when the weather or environment is very hot.Cheers
The tar is roads that have quantities to make them deal with the construction. The liquid is a mix of asphalt and can be adhesive and waterproof.
The iron bars are used for securing the place and things. plastic furniture is used to make suitable furniture and is used for chemical stability etc. The metal jeweler is of titanium, cobalt and stainless steelLearn more about the following minerals.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Complete question:
Now you are ready for your first major assignment. Your colleagues are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants.
Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Note: You will find the tables in the attached files
Answer:
Probably the seized tusk belonged to elephant number eight.
Explanation:
Potentially, the seized tusk might belong to individual number eight. In both the tusk and the elephant, the genetic analysis resulted in the same-sized alleles for each locus.
FH19: 193 193FH60: 147 147FH67:97 103FH71: 62 62FH129: 152 160The fact that, among the ten individuals of the population, only the individual number 8 matches the tusk for SRT loci, suggests that it belongs to the animal, but it does not ensure it 100%.

Explanation:
(b) Explain how the addition of a phosphate group to certain amino acids of Brec likely affects the tertiary structure and function of Brec. Explain how
the addition of a small RNA could prevent the activation of kinase D?
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
1. Adding the phosphate group to the amino acid chains is known as phosphorylation. This attachment affects the tertiary arrangement and function of Brec.
Amino acids join together to form the protein that needs to be stimulated and deactivated for proper functioning.Protein phosphorylation is very crucial in post-translation modification.For protein function, it acts as an activator, inhibitor, reversibly on and offs the switch.Phosphorylation assures a reversible process to the cell to transmit signals for the cell functioning.Therefore, Brec activity can be controlled by the phosphorylation of proteins.2. Small RNA's are RNA fragments which is around 150 nucleotide in length.
Functionally significant small RNA's such as siRNAs, microRNAs scaRNAs and many other acts as regulatory molecules which target and adheres to the mRNA transcripts.This binding inhibits the translation process or degrades the mRNA by activating the RNA interference (RNAi) pathway.RNAi pathway is used to suppress the activation of the kinase D.To learn more about phosphorylation and small RNA follow the given link below:

Des a magnetic field flows though the inside of a magnet
Answer:
Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.
Explanation:
Answer:
However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole. Thus the magnetic field lines form a closed loop and do not have any ends.
Explanation:
So it's probably YES.
