Explanation:

The fully assembled ribosome in bacterial cells is described as 70S.

Ribosomes are cellular structures responsible for protein synthesis. They exist in both bacterial and eukaryotic cells, but their sizes differ. Ribosomes are characterized by their sedimentation coefficient, denoted by the letter 'S.'

In bacterial cells, the fully assembled ribosome consists of a large subunit and a small subunit, combining to form a 70S ribosome. The large subunit is approximately 50S, while the small subunit is around 30S. When these two subunits come together, they form the 70S ribosome.

The other options listed, 50S, 80S, and 30S, refer to either the individual subunits or ribosomes found in different organisms. The 80S ribosome, for example, is characteristic of eukaryotic cells rather than bacterial cells.

Therefore, the correct option is option (a)

If shark fossils are found below flowering plant fossils, it suggests that the sharks existed before the flowering plants. This is because the principle of superposition states that, in a series of undisturbed rock layers, the oldest rocks will be at the bottom and the youngest rocks will be at the top. Therefore, if shark fossils are found in lower rock layers than flowering plant fossils, it means that the sharks lived and died before the flowering plants evolved and were fossilized.

Hi! Pain receptors, also known as nociceptors, play a crucial role in our body's ability to detect potentially harmful stimuli such as heat, cold, or pressure. In conclusion, having pain receptors sensitive to various vigorous stimuli, such as heat, is advantageous because it provides protection, helps us adapt, and maintains overall well-being.

Having pain receptors sensitive to various vigorous stimuli is advantageous for a few reasons:1. Protection: Sensitivity to different types of stimuli allows the body to quickly respond to potential threats. For example, when we touch a hot surface, the pain receptors detect the heat and send a signal to the brain, prompting us to withdraw our hand to avoid further injury.2. Healing: Pain signals help the body identify areas that need attention and promote the healing process. For instance, pain from an injury encourages us to protect the affected area, allowing it to heal.3. Adaptation: Our sensitivity to pain allows us to learn from potentially harmful experiences and adapt our behavior to avoid them in the future. For example, after experiencing the pain from touching a hot object, we become more cautious around heat sources.4. Overall well-being: Pain receptors also play a role in maintaining the body's overall well-being. Detecting changes in temperature, pressure, or other environmental factors enables the body to adapt and maintain homeostasis, ensuring optimal functioning.

An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.

Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.

They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.

Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.

What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.

Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.

This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.

Glacial erratics are the name given to these rocks. Erratics serve as a log of a glacier's journey. Complex flow patterns can be discovered by looking for the bedrock units that match with erratics. Thus option A is correct.

The rocks and the ground below are both eroded as a result of the friction caused by glaciers carrying rocks. In this manner, glaciers pulverize rocks and remove dirt. Mountain valleys with steep sides are created by advancing glaciers carving out basins. Moraine, an eroded debris, is frequently seen on and surrounding glaciers.

Mechanical weathering causes the rock on valley walls to become loose as glaciers flow, where it then falls as debris. Rocks of any size, from enormous boulders to silt, can be carried by glaciers. Over many years and decades, these rocks can be transported a great distance.

Explanation:

The F2 generation of dwarf violet would be 3/16.

C is the correct answer.

This dihybrid cross is usual. Due to the homozygosity of both parents, two distinct types of gametes—TV and (tv)—will be produced. The genotype (TtVv) will be heterozygous in the F1 plant. The F1 plants produce four different types of gametes: (TV), (TTV), (tTV), and (tTV).

The ratio of phenotypes in the F2 progeny is 9:3:3:1. One (TTvv) and two (Ttvv) of these dwarf plants had violet, making a total of three recombinants that are produced three times per sixteen progenies.

A mating experiment between two organisms that are equally hybrid for two traits is referred to as a dihybrid cross. A heterozygous organism is one that possesses two distinct alleles at a certain genetic location, making it a hybrid.

A phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another. The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.

Answer: B

Explanation:

DNA is duplicated so that each new daughter cell inherits an identical copy of the genome, while the centrosome is duplicated to help initiate the formation of the two poles of the mitotic spindle and to supply each daughter cell with its own centrosome.

Since plants and photosynthetic protists do not have the machinery for being heterotroph but they can make their own food in the presence of chloroplast, this is the reason why they possess chloroplast. Animals cells on the other hand cannot perform photosynthesis and hence do not possess chloroplast.

Heterotroph is one of the types of mode of nutrition. In this the organism obtains their food from some other organism that can either be plant or another animal. The example of heterotrophs are all the animals and humans.

Photosynthesis is the process of synthesizing food by capturing the sunlight energy and releasing oxygen as the by-product.

As seen from the Punnett square, 50% of the offspring will be carriers of PKU (Dp).

What is the genetic basis for Phenylketonuria (PKU) and how is it inherited?

Phenylketonuria (PKU) is a genetic disorder that is caused by a recessive allele (p). To be affected with PKU, an individual must inherit two copies of the recessive allele, one from each parent.

If a homozygous dominant man (who has the genotype DD) marries a woman with PKU (who has the genotype Pp), the probability of their child being a carrier of PKU (having the genotype Pp) is 50%. This is because each parent has a 50% chance of passing on either their dominant D allele or their recessive p allele to their child. When the child inherits one D allele from the homozygous dominant father and one p allele from the mother with PKU, the child will be a carrier for PKU.

The Punnett square for this cross is as follows:

| D | D

p | Dp| Dp

p | Dp| Dp
