Explanation:

Hemolytic Disease of the newborn (HDN, Erythroblastosis Fetalis) is a blood disorder occurring at or around birth, where the blood groups of the mother and baby are not compatible. It occurs when the antibodies from a Rhesus negative (Rh-negative) mother, who has been sensitized from previous pregnancies or other means (transfusion etc), gives birth to an Rh-positive baby, and the blood of the mother and the baby eventually mixes. This causes the anti-Rhesus antibodies in the mother's blood to attack the Rhesus antigen (Also Called Anti-D antigen) on the baby's red blood cells, causing hemolysis that leads to several unpleasant symptoms.

Children of Rh-positive mothers are not at risk of developing HDN, because the mother does not produce anti-Rh antibodies since she is positive, hence there will be no antibodies to cross the placenta and react with the baby's rhesus antigens for Rh-positive babies.

Answer:

The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair.

Explanation:

Answer:

Because it has four electrons in its second orbital, which can accommodate eight, carbon can combine in many different ways, and it can form very large molecules. Carbon bonds are strong and can stay together in water. Carbon is such a versatile element that almost 10 million different carbon compounds exist.

Explanation:

Chemical potential energy is defined as the energy present or stored in the chemical bonds of a substance. The decreasing order of the molecules with chemical potential energy is solid, liquid, and gas.

The correct answer is:

Option B. Carbon dioxide

The chemical potential energy can be explained as:

1. ATP and NADH are the energy currency of the cells, such that these molecules yield energy when the bonds are broken down.

2. Glucose is a solid compound that will have a high chemical potential energy as compared to carbon dioxide.

3. Carbon dioxide is a gaseous compound that will have the least chemical potential energy as compared to ATP, NADH, and glucose.

Thus, carbon dioxide will have the least potential chemical energy.

Fun Fact - Locusts are actually species of short-horned grasshoppers, they often gather in large swarms and can destroy entire fields of crops, because a single grasshopper can eat half its body weight in plants per day.

There are four trophic levels in the given food chain, i.e., producer, primary consumer, secondary consumer, and tertiary consumer.

A food chain is a network of connections in a food web that begins with producer organisms and ends with a predator, detritivore, or decomposer species.

In the given food chain, grass is produces, grasshopper is primary consumer, frog is secondary consumer, while snake is tertiary consumer.

Thus, there are four trophic levels in the given food chain.

Answer:

c

Explanation:

Mendel's principle of independent assortment holds only when traits are on different chromosomes.

The independent assortment principle states that genes assort independently of one another. In order words, traits are independently inherited by offspring from parents. For example, the trait for eye color is independently inherited from skin color, height is independently inherited from feet size, and etc.

This principle only holds true when genes are located far away from one another on the same chromosome or when they are on different chromosomes entirely. Once genes are close to one another on the same chromosome, they become linked together and no longer independently inherited.

The correct option is c.

The mean diameter of  phytoplankton cell is 650 micrometers at a distance of 25 kilometers from the sea shore.

The mean diameter of  phytoplankton cell is 650 micrometers because at every 5 kilometers, decrease occur in the diameter of phytoplankton cell about 50 micrometers and we know that the the diameter of phytoplankton cell is 900 micrometers so for 25 kilometers there is 250 micrometers decrease occur in the diameter of phytoplankton cell.

So this 250 micrometers are substracted from 900 micrometers we get 650 micrometers. So we can say that the mean diameter of  phytoplankton cell is 650 micrometers at 25 kilometers distance from the sea shore.

Explanation:

Interactions between different organisms are numerous and are usually described according to their positive (beneficial), negative or neutral effect on others.

The interactions between living things and their non living environment makes up a total ecosystem; understanding any one part of it requires knowledge of how that part interacts with the others. Ecosystems do not ‘collapse’ but do change in function, structure and composition over time due to natural or human disturbance (examples include the impact of drought, flooding, mowing and herbicides).

Answer:

b. Clostridium botulinum.

Explanation:

The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells  Moreover, Clostridium botulinum is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.

The organism that does NOT produce an enterotoxin among the options given is b) Clostridium botulinum. Clostridium botulinum is a bacterium known for producing botulinum toxin, which is a neurotoxin rather than an enterotoxin. It does not, however, create an enterotoxin.

The severe sickness known as botulism is brought on by the botulinum toxin, which predominantly affects the nervous system.

Although enterotoxins can induce diarrheal disorders and are linked to gastrointestinal symptoms, an organism need not produce an enterotoxin to be pathogenic. The host's sensitivity to infection and the infectious dosage are other important variables.

Answer:

Asexual Reproduction

Explanation:

As the bacteria cell is dividing on its own to create more bacteria, it is performing asexual reproduction as it is not reproducing with a secondary bacteria cell.

Asexual reproduction is the process by which a bacteria cell that divides to create two exact copies of itself.  Thus option C is correct.

Bacteria reproduce by the process of asexual reproduction which is mainly binary fission, where the offspring produced from parent are  similar.

In this process parent cell is undergo division and separated into two new daughter cells. Each daughter cell get one copy of its parent DNA.

No spindle apparatus formation occur in binary Fission. In this process, the DNA molecule undergo replication and attaches each copy to various parts of the cell membrane

For example, Prokaryotes like  E. coli, Archaea and some eukaryotes like euglena reproduce through binary fission.

The advantage of binary fission is very fast and it requires single organism or parent.

Thus option C is correct.
