Answer:

The term extinction's dictionary meaning, is the process of when a species, plant, or any other term for animal family, goes extinct. In more, basic terms, it means when a certain species of animal dies out completely.

This can happen due to several reasons, some being massive natural disasters. Others die out due to an unknown predator entering an ecosystem in which it doesn't belong, therefore disbalancing it.

Examples of extinct animals are Dinosaurs, but their exact reason for going extinct is unkown, there are only theories.

There are also many animals in danger of going extinct, for example Bees.

Answer:

Metabolic pathways in monarch butterflies are as follows:

Explanation:

They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.

They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.

During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose.  The conversion of fat also releases little water which help them to survive during winter.

1) Glycolysis:

2. Kreb's Cycle:

The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.

3. Oxidative Phosphorylation:

The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.

When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.

This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.

The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.

Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

Answer:the radiation of the Sun’s electromagnetic waves

Explanation:

Answer:

Explanation:

Using the concept of de Broglie wavelength under relativistic conditions to determine the spatial limits for electron range.

de Broglie wave-length [tex]\lambda = \dfrac{h}{p}[/tex]

where;

h = plank's constant

p = momentum of particle which is expressed as:

[tex]p = \dfrac{\sqrt{k^2+2kmc^2}}{c}[/tex]

replacing the expression for (p) into [tex]\lambda = \dfrac{h}{p}[/tex], we have:

[tex]\lambda = \dfrac{h}{\dfrac{\sqrt{k^2 +2kmc^2}}{c}}[/tex]

[tex]\lambda = \dfrac{hc}{\sqrt{k^2+2kmc^2}} --- (1)[/tex]

here;

c = velocity of light = 3 × 10⁸ m/s

h = 4.13 × 10⁻¹⁵ eV.s

i.e.

hc = (4.13 × 10⁻¹⁵ eV.s)(3 × 10⁸ m/s)

hc = 1240 eV.m

The electron's rest energy (mc²) = 0.511 × 10⁶ eV

For the elctrons;

the minimum accelerated voltage = 40kV

the maximum accelerated voltage = 100 kV

the minimum K.E of the electron K = eΔV

K = e × 40 kV

K = 40 KeV

K = 40 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(40 \times 10^3 \ eV)^2 +2(40 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(80000\times 511000))eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{((1600000000) +(40880000000)eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(42480000000) \ eV}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{206106.769 \ eV}}[/tex]

[tex]\lambda = 0.062 \ nm[/tex]

[tex]\mathbf{\lambda = 6.20 \ pm}[/tex]

The maximum K.E of the electron K = eΔV

K = e × 10 kV

K = 10 KeV

K = 100 × 10³ eV

From equation (1);

[tex]\lambda = \dfrac{hc}{\sqrt{k^2 +2kmc^2}}[/tex]

[tex]\lambda = \dfrac{1240 \ eV.nm}{\sqrt{(100 \times 10^3 \ eV)^2 +2(100 \times 10^3 \ eV)(0.511 \times 10^6 \ eV})}[/tex]

[tex]\lambda = 0.037 \ nm[/tex]

[tex]\mathbf{\lambda = 3.70 \ pm}[/tex]

As a result, the spatial limits for the electron's range span from 6.02 pm to 3.70 pm.

Explanation:

Answer: Anterograde direction.

Explanation:

Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.

The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.  

This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.

A disorder that is a result of shortage of proteins in children is Kwashiorkor

Explanation:

Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)

Hopefully this helps.

Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.

Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.

Other terms for kwashiorkor include:

Answer:

Explanation:

After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.

The digestion of lipids and protein begin in the dudoneum of small intestine.

Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.

The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

chromosomes

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.

In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.

Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.

On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
