The skin on our lips differs from the skin on the rest of our faces in a few ways. First, the lips have no oil glands, which means they don't produce natural oils to keep them hydrated.

Second, the lips are very thin, which makes them more susceptible to drying out. Third, the lips are constantly exposed to the elements, such as cold air, wind, and sun exposure.

These factors can contribute to chapped lips, especially in the winter. When the weather is cold, the air is drier, which can further dehydrate the lips. Additionally, the cold air can irritate the lips, making them more likely to crack and peel.

Chapstick helps to protect the lips from the elements and keep them hydrated. The waxy layer of chapstick creates a barrier between the lips and the air, which helps to prevent moisture from evaporating. Some chapsticks contain ingredients that help soothe and heal chapped lips.

Answer:

Light colored peppered moths decreases in number and dark colored peppered moths increases.

Explanation:

The population of light colored peppered moths decreases whereas the dark colored peppered moths increases in number because the light colored peppered moths are visible to the predator birds  whereas the dark colored peppered moths are not visible due to dark coating of the trees so they are saved from the birds and therefore, increase in population of dark colored peppered moths occurs and decrease occur in light colored peppered moths population.

Carrying capacity may be impacted by prey biomass.

The word "carrying capacity" refers to the most individuals of a species that can coexist for an extended period of time in a certain environment. The availability of prey biomass commonly impacts the carrying capacity of predators in predator-prey dynamics.

When prey biomass increases, there is frequently more food available for predators, which could lead to an increase in the number of predators. Thus, the carrying capacity of the blue whales are affected by biomass.

1. Farmers began to domesticate maize around 9,000 years ago in Mesoamerica, which is the region that includes present-day Mexico and parts of Central America.

2. The first domestication of maize occurred in the area that is now southern Mexico. The indigenous peoples of this region, such as the Maya and Aztecs, were the first to cultivate maize and develop it into a staple food crop.

3. The wild grass from which maize originated is called teosinte. Teosinte is a type of wild grass that is native to Mexico and Central America, and it is the closest wild relative of modern maize. Over thousands of years, indigenous peoples in this region selectively bred teosinte to produce the maize that we know today.

Lamarck's theory basically says that traits that are developed over time can be passed on (Theory of Inheritance of Acquired Characteristics), which is incorrect. Darwin is correct that only traits possessed at birth can be passed on.

Lamarck believes that the traits which you learn or develop over time could be passed on. As per Darwin believed that you passed on the traits you possessed at birth. This the option B is correct.

The theory of Lamarck is based on the aspects of the evolution and is the principle that the physical changes in an organism during their lifetime as the development of the organs.  

The use of the parts increases and can be transmitted to the offspring. The theory focuses on the use and disuse, an organism that is driven by greater complexity, effects of the environment, and needs.

Fossil record for continental drift theory is one of the best support evidence of tectonic plates movement.

One type of evidence that has been used to back up the Theory of Continental Drift is the fossil record. Scientists have found fossilised remains of related plant and animal species in rocks that are similar in age. These rocks were found along the coasts of numerous continents.This suggests that the continents may have once been linked.

For example, fossils of the freshwater reptile Mesosaurus have been found in Brazil and western Africa. In addition, fossils of the Lystrosaurus have been found in Antarctica, India, and Africa.Tectonic plates can move inside the lithosphere because it is heavier and stronger than the rock beneath it.

Answer:

Meiosis

Explanation:

Answer:

Reproduction is the biological process by which organisms produce new individuals of the same species. It is a fundamental characteristic of life, and is essential for the survival and continuation of a species. Reproduction can occur through two main methods: sexual reproduction and asexual reproduction.

In sexual reproduction, two individuals (usually of different sexes) combine their genetic material to produce offspring. This typically involves the fusion of male and female reproductive cells (sperm and egg) during fertilization. The resulting offspring have a unique combination of genetic traits inherited from both parents.

In asexual reproduction, a single individual can produce offspring without the involvement of another individual. This can occur through various methods such as budding, fragmentation, or parthenogenesis, depending on the specific organism.

Reproduction can also be divided into two other categories: primary reproduction and secondary reproduction. Primary reproduction refers to the process of producing the first generation of offspring, while secondary reproduction refers to the process of producing subsequent generations.

Reproduction is important for the survival and continuation of a species. It allows populations to grow and adapt to changing environmental conditions, and helps to maintain genetic diversity within a species

Explanation:

Answer:

Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.

A mutation known as a substitution is one in which one base is switched out for another. A codon that encodes a different amino acid may be changed, which would result in a minor modification to the protein that is created.

Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that aid in: Dissect food.

In terms of genomics, substitution is a sort of mutation where one nucleotide is changed for a different nucleotide. The phrase can also be used to describe switching out one amino acid for another in a protein.

Thus, A codon that encodes a different amino acid may be changed, which would result in a minor modification to the protein that is created.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

Muscle twitching can be explained by the temporal summation action of synapse. Thus, the correct option is B.

Muscle twitching is also called as muscle fasciculation. Muscle twitching involves a small muscle contraction in the body muscles. Muscle twitches are caused by the muscles tightening up or contracting involuntarily. In other words, it occurs when we are not actually controlling their actions. Muscle twitches can happen for a lot of reasons, such as stress, too much caffeine, a poor diet, exercise, or as a side effect of medicines.

Temporal summation is a physiological effect when the second muscle twitch becomes much higher than the first twitch, forming a tension in the muscle fiber. This happens because, after the first twitch of the muscle, the second stimulation is applied before the muscle even relaxes however both the stimuli are of equal strength.

Therefore, the correct option is B.
