Chromosome in parental cell is diploid i.e 2n

where as the gamete chromosome is haploid and is represented as "n"

Thus, chromosome number in gamete is just the half of the chromosome number of parent.

Hence, option D is correct

Answer:

Unlike the chelicerae of arachnids, mandibles can often be used to chew food. Mandibulates also differ by having antennae, and also by having three distinct body regions: head, thorax and abdomen.

Acid rain harms numerous animals and plants. Thus, the food web suffers. Acid rain kills lake phytoplankton. As a result, phytoplankton-dependent insects die. Therefore, option (C) is correct.

Acid rain, also known as acid deposition, is an all-encompassing word that refers to any form of precipitation that contains acidic components, such as sulfuric or nitric acid, and that falls to the ground from the atmosphere in either a wet or dry form. Acid precipitation can take several forms, such as rain, snow, fog, hail, or even dust.

Rain that contains acid can provide significant challenges for a wide variety of flora and fauna. As a direct consequence of this, the entire food web is disrupted. For instance, phytoplankton in lakes might perish as a direct result of acid rain. As a result of there being less phytoplankton available, the insects, which get their nutrition from it, are starting to starve to death.

Therefore, option (C) is correct.

Crossing over during meiosis is a process where homologous chromosomes exchange genetic material. It occurs during prophase I of meiosis and can result in genetic recombination, where the offspring receives a combination of genes from both parents.

Mutations can occur in the genetic code due to errors during DNA replication or exposure to mutagens such as radiation or chemicals. Mutations can be of various types, such as point mutations, deletions, insertions, and chromosomal rearrangements. Some mutations can have harmful effects, while others may have no effect or even be beneficial.

Therefore, the option (a) describes a normal process of DNA replication but does not represent crossing over or a mutation. Option (b) is partially correct but does not describe the specific process of mutation that occurs during crossing over. Option (c) is not necessarily true for all cases of sickle cell anemia as it can also occur due to mutations in the mother's somatic cells, not just the gametes. Option (d) is correct but does not provide any information about the specific process of mutation during crossing over in meiosis.

Explanation:

the ER is responsible for the creation of lipids and membranes and ribosomes are responsible for protein synthesis.

Answer:B:Cells contain protein,and viruses contain only carbohydrates.

Explanation:

The generation time of this bacterium is approximately 0.33 hours. This means that, on average, it takes 0.33 hours for the bacterium population to double in size under the given conditions.

To determine the generation time of a bacterium, we can use the formula:

Generation time (t) = (time elapsed (T)) / (number of generations (n))

In this case, the initial number of bacteria (N₀) is 10, and after 2 hours, the population size (N) is 640. To calculate the number of generations, we can use the formula:

N = N₀ x (2ⁿ)

Solving for n:

640 = 10 x (2ⁿ)

Dividing both sides by 10:

64 = 2ⁿ

Taking the logarithm base 2 of both sides:

log₂(64) = n

n = 6

So, the number of generations (n) is 6.

Now we can calculate the generation time:

Generation time (t) = T / n = 2 hours / 6 = 0.33 hours

Therefore,  the generation time of this bacterium is approximately 0.33 hours.

The right response is that ribose-5-phosphate and carbon dioxide are created from glucose-6-phosphate.

The glucose-6-phosphate is converted into ribose-5-phosphate, which is the five-carbon sugar molecule and carbon dioxide, after entering the pentose phosphate pathway. Following the entry into the route, glucose-6-phosphate is initially converted into 6-phosphogluconolactone by the enzyme glucose-6-phosphate dehydrogenase.

The generation of NADPH also occurs during the conversion of glucose-6-phosphate to the lactone molecule. By the action of the enzyme lactonase, 6-phosphogluconate is created from the 6-phosphogluconolactone that is generated. This is further decarboxylated and hydrolyzed into carbon dioxide and ribose-5-phosphate by the action of the enzyme 6-phosphogluconate dehydrogenase. The hummingbird's flight muscles convert glucose-6-phosphate in order to produce NADPH and protect against oxidative stress.

The complete question is:-

What is the fate of glucose 6-phosphate that enters the pentose phosphate pathway in the flight muscles of hummingbirds? Glucose 6-phosphate is converted to carbon dioxide and ribose 5-phosphate.

The "host range" defines the limitations of the type of cell that a virus can invade. Host range refers to the specific types of cells and organisms that a virus can infect. These limitations are dictated by various factors, such as the presence of specific cell surface receptors that the virus can bind to and the compatibility of the virus with the host cell's machinery for replication.

Different viruses have distinct host ranges, with some being able to infect only specific species or cell types, while others can infect a broader range of hosts. A virus's host range is an essential aspect of its biology, as it determines the potential reservoirs for the virus in nature and its ability to spread and cause disease.

Understanding a virus's host range is crucial in the study of viral diseases and the development of strategies for prevention and treatment. Limitations in a virus's host range can be exploited in the design of antiviral therapies, as well as in the development of vaccines to protect against viral infections.

In summary, the host range of a virus defines the limitations of the type of cell it can invade, which plays a critical role in its ability to spread and cause disease.

I don't have information about which forest you are referring to, so I am unable to provide a specific response to Step 4 and 5. However, here is some general information about the topics mentioned in these steps.

Step 4 - Biodiversity:

Biodiversity refers to the variety of living organisms that exist in a given area. The biodiversity of a forest can vary, depending on factors such as the climate, soil type, and topography. Forests can provide habitat for a wide variety of animals, including mammals, birds, reptiles, amphibians, insects, and other invertebrates. Similarly, forests can support a range of plant species, from understory herbs and shrubs to towering canopy trees.

Example: One popular wildlife that might live in a forest is the White-tailed Deer. They adapt to living in the forest by having keen senses and excellent camouflage that help them evade predators. They are a keystone species in the food chain, as predators like wolves and cougars hunt them for food. Some interesting facts about White-tailed Deer are that they have scent glands on their legs that produce a distinctive smell that they use to signal other deer, and their antlers shed and regrow annually.

Another vegetation example of a plant that is not a tree in the forest is the Wild sarsaparilla plant. This plant is adapted to living in the understory of the forest where it gets the limited sunlight because of the canopy trees above. It has long, thin leaves that allow it to capture as much light as possible. The wild sarsaparilla plant is eaten by a few animals like rabbits, moose, and deer.

Step 5 - Timber and Wildlife Management:

Timber harvesting or logging is the process of cutting down trees for commercial use. Forests are managed to ensure sustainable timber harvesting, which involves planting new trees to replace those that are harvested and managing the forest to prevent diseases and pests.

Wildfires, prescribed, or controlled burns are managed in the forest to prevent catastrophic fires. These controlled burns or wildfires can help get rid of the debris on the forest floor and help to prevent uncontrollable fires that can start from lightning strikes.

Hunting or fishing is typically managed in the forest to minimize the impact on wildlife populations. Hunting and fishing regulations help control the number and type of animals that can be harvested, the season and time of day when they can be hunted, and the methods allowed. The aim is to protect wildlife populations and maintain biodiversity while also providing recreational opportunities for people.
