Explanation:

Mensuration is a natural process in which there is discharge of dead endometrial cells, unfertilized ovum, blood from broken capillaries and mucous membrane from uterus every month. As it is a natural process, it occurs every month to discharge the unwanted substances from our body. It makes our body free from the unwanted substances which can cause infection. It releases the unfertilized hormones prodoced in uterus of female.

Answer:

These are all examples of local  anaesthetics a) marcaine(Bupivacaine) b) xylocaine(lidocaine) c) novocain(procaine) are all  examples of local anaesthesia

Explanation:

Generally local anaesthetic are drugs used in clinical anaesthesia  to block or  suppress the sensation  of pain  at the specific  region or part of the body where it was applied.The effect of the application depends on the dose applied and the period of application.

The work  by inhibiting transmission of action potential as nerve transmission,through blocking of sodium channels. Thus depolarization is prevented,and nervous transmission to the brain (and therefore pain)  is suppressed

Generally pain transmission fibres are blocked first,motor sensation are lost afterwards ,therefore touch sensation and pressure are the last to be lost by the local region.

They are classified into  Amide or ester group based on the chemical structures.The  examples in the question are amides.

Subcutaneous or epidural administrations  can be used to apply

Explanation:

Hope it helps.

The flowing in and out of tides is called ebb and flow. Details about tides can be found below.

A tide is the periodic change of the sea level, particularly when caused by the gravitational influence of the sun and the moon.

According to this question, a tide comes in and out every day like clockwork.

The in-flowing tide is called flow while the out-flowing tide is called ebb. Therefore, the flowing in and out of tides is called ebb and flow.

food web

Explanation:

Food web is an interconnection and assimilation of different good chains. Many food chains are interlinked a hence a food web is created. This represents what is eaten by which organism.

Answer:

Photoperiodism

Explanation:

The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.

When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

A. Speciation

Explanation:

Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

When the genetic drift occurs due to various factors and results in the formation of a new species it is called speciation. Thus, option A is correct.

Speciation is the formation of a distinct species from the original population because of the genetic drift that caused evolutionary changes essential for survival.

The species are separated from their original population leading to variation in the gene pool resulting in reproductive isolation and finally, the new species is formed.

Therefore, option A. speciation results in distinct species.

Explanation:

Medulla oblongata controls consciousness and arousal (the reticular formation) and its three vital reflex centers control the blood vessels diameter, heartbeat and breathing rate (the involuntary actions). This makes option D correct. The lower part of brain stem forms the hind brain which comprises of medulla oblongata, pons and cerebellum. This makes option C incorrect as medulla is not part of forebrain. Cerebellum is the convoluted subdivision of brain stem and is associated with coordination of muscular movement, muscle tone and balance i.e. the voluntary actions. Option B is incorrect. Spinal cord, along with brain, forms central nervous system which serves to integrate the sensory inputs from internal and external environment as received by sensory neurons and process and finally transmit the nerve impulses to effectors (muscles and glands). This makes option A incorrect.

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)

In the citric acid cycle, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

--------------------

The resumed steps of the Citric acid cycle are as follows,

1) Acetyl CoA joins an oxaloacetate molecule, which is a 4C molecule. They release the CoA group and form a 6C molecule called Citrate.

                      Acetil CoA + Oxalacetato → Citrato + CoA group

2) Citrate turns into an isomere Isocitrate

3) Isocitrate oxidates and release 1 CO₂ molecule, producing an α- ketoglutarate molecule -this is a 5C molecule-. Meanwhile, NAD+ reduces to NADH.

                    Isocitrate + NAD+ → α-cetoglutarate + CO₂ + NADH

4) α-ketoglutarate oxidates and release 1 CO₂ molecule, producing a 4C molecule, which joins a Coenzyme A producing Succinyl-CoA. Meanwhile,  NAD+ reduces to NADH.

          α-cetoglutarate + NAD+ → 4C molecule + CO₂ + NADH

          4C molecule + Coenzyme A → Succinil-CoA

5) CoA from Succinyl-CoA is substituted with a phosphate group, which then forms ATP. The final product is Succinate and ATP

       Succinyl-CoA + Phosphate group + ADP → Succinate + ATP + CoA

6) Succinate oxidizes and forms Fumarate, a 4C molecule. FAD+ forms FAH₂

                     Succinate + FAD+ → Fumarate + FADH₂

7) A water molecule and Fumarate produce Malate, which is another 4C molecule

                                Fumarate + H₂O → Malate

8) Finally, malate oxidizes and oxalacetate regenerates -the initial 4C compound-. NAD+ reduces to NADH.

                     Malato + NAD+ → Oxalacetate + NADH

So, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

Answer:

Molecules are defined as a combination of two or more same or different atoms bounded together.

Types of molecules are as follows:

Diatomic molecules: A molecules which is consist of only two atoms of different or same elements are called diatomic molecules. Example: O2 and CO.

Heteronuclear diatomic molecules: A molecule that composed of two atoms of the same element is called heteronuclear diatomic molecules. Example: Hydrogen (H2) and Nitrogen (N2).

Homonuclear diatomic molecule: A molecule that composed of two atoms of different elements are called homonuclear diatomic molecule. Example: Hydrochloric acid (HCl) and Hydrogen fluoride (HF).

A molecule can be defined as a group of atoms that constitute the shortest and identifiable unit in which a substance is divided.

The outer membrane, a peptidoglycan layer, periplasm, and cell membrane

Explanation:

The predatory bacterium will have to penetrate the cell wall and the cell membrane of the gram-negative bacterium before getting access to the cytoplasm.

In order to penetrate the cell wall of a gram-negative bacterium, the predatory bacterium will have to penetrate the components of the cell wall which consists of an outer membrane, a thin peptidoglycan layer, and a gel-like matrix known as the periplasm.

Thereafter, the predatory bacterium will have to penetrate the cell membrane before eventually getting access into the cytoplasm of the prey bacterium.

The peptidoglycan layer or the outer membrane will be the first structure penetrated by the B. bacteriovorus.

In the given case, the predatory bacterium, that is, B. bacteriovorus needs to penetrate the cell wall and the membrane of the gram-negative bacterium prior of getting within the cytoplasm of the host bacterium.

To penetrate the cell wall of a gram-negative bacterium, the predatory bacterium have to infiltrate the cell wall components comprising,
