The condition of malfunctioning or unusual functioning of body or organs is known as disease. it might be due to genetic, pathological or physical reasons or even due to lack of intake of proper diet and lack of enough sleep. it is classified into two types:

Apes were basically monkeys. They walk on their hands and feet but crouched. There's a bunch of theories saying that humans evolved from apes. As apes evolved, they started walking upright.

The most genetic information is inherited in humans on the x-chromosome.

In bacteria, each messenger RNA (mRNA) serves as a template for the production of one or more particular proteins. Messenger RNAs (mRNAs) carry information from DNA. Translation is the process by which the primary amino acid sequence of a protein is established from the nucleotide sequence of an mRNA molecule.

Their mother passes one copy on to them through the egg, while their father passes the other one along sperm. Each egg and sperm have a single set of 23 chromosomes. Two copies of each chromosome and two copies of each gene are present when the sperm fertilizes the egg, resulting in the formation of an embryo.

Three separate processes responsible for the genetic diversity.

The adrenal gland helps to maintain homeostasis by producing hormones that regulate metabolism, stress response, and other bodily processes.

What exactly is homeostasis?

Homeostasis is the ability of a living organism or system to regulate its internal environment to maintain a stable equilibrium, such as temperature or pH, despite changes in external conditions. It is a crucial factor in allowing organisms to function normally in their environment.

The pineal gland helps to maintain homeostasis by secreting melatonin which helps to regulate the body’s circadian rhythm and helps to regulate sleep and wake cycles. Together, these two glands help to keep the body in a balanced, homeostatic state.

Answer:

While artificial selection is certainly a form of experimental evolution, often the meaning of the term 'experimental evolution' is confined to controlled natural selection, excluding artificial selection

Explanation:

The positive transcription factor will help in maintaining the stimulus for homeostasis or even accelerate it. Whereas the negative transcription factor will oppose the effect of the stimulus, it can either increase it or decrease it.

Homeostasis is the maintenance of a steady and equilibrated physical, chemical and internal state of the body. The example of positive transcription factor is: activation of one clotting factor in the body initiates a cascade for the activation of all the other clotting factors.

Negative transcription factor has the example of blood glucose levels of the body. If the level increase transcription factors cause the release of insulin from the pancreatic cells to maintain the homeostasis.

The difference between K-selected species and R-Selected species is that the former posses a type I survivorship curve while the latter has type III survivorship curve.

A Type III survival curve is more likely to be present in K-selected species. Type I survivorship curves are typical in r-selected species. Graphs called survival curves provide a visual representation of the proportion of a population that is still alive at various ages. R-Selected species have evolved to survive in unstable and unpredictable surroundings. They produce a great number of tiny young.

The offspring of r-selected animals are comparatively self-sufficient at birth and do not get a lot of resources or parental care. Examples of r-selected species include plants like the dandelion and marine creatures like jellyfish.

Species chosen by K are adapted to predictable, steady surroundings. K-selected species tend to have populations that are roughly at their carrying capacity. These species have long generation times, and larger but fewer offspring overall. An example of a K-selected species would be an elephant or a human.

Answer: Correct option (d) Either less than or equal to one. Explanation: velocity/speed ≤ 1Read more on

Explanation:

Option A: Epithelial tissue types found in the lungs are responsible for mucous secretion in the lungs.

About 30% of the respiratory epithelium's total cell population are goblet cells. They create mucinogen, which when released into an aqueous environment becomes hydrated and is known as mucin. As soon as the mucin is combined with additional components in the wet environment, it is referred to as mucus. Thus, option A is the appropriate choice.

The first line of defense against the onslaught of irritants that 500 L of air an hour of air inhalation puts into the lungs is mucus secretion. The airway epithelium can be harmed by the gases, microorganisms, soot, and dust that are inhaled. As a result, mucus secretion happens extraordinarily quickly—in only a few milliseconds.

The genotypes of the offspring must be readily determined from their phenotypes.  

A heterozygous individual has two different alleles. Therefore it would have the genotype Aa. An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete.

A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.

The ability to live in a highly acidic environment and the ability to withstand very hot temperatures are the adaptations that allow thermophiles, a type of bacteria, to live within the hot springs of Yellowstone National Park.

what is Adaptation?

Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment.

The main feature of Yellowstone National Park is the presence of very hot and acidic water. Starting as rain on the surface, water from hot springs seeps through the bedrock beneath Yellowstone and is superheated by Yellowstone's magma system.

Thermophilic proteins have several adaptations that give them the ability to maintain structure and function at extreme temperatures. Thermophiles, for example, have specialized enzymes that use additional hydrogen bonds, salt bridges, and disulfide bonds to resist denaturation at very high temperatures, strengthening proteins to resist unfolding increase.

Answer:

The calico cat displays a mixture of red- and black-based colors, depending on which of its two X chromosomes has been inactivated. The allele coding for orange hair color is dominant, while the allele for black color is recessive - although this doesn`t matter much since only one allele is expressed.

Because the genetic determination of coat colors in calico cats is linked to the X chromosome, calicoes are nearly always female, with one color linked to the maternal X chromosome and a second color linked to the paternal X chromosome.

To create a calico (or tortoise-shell) pattern, one of the X chromosomes must carry the black gene and the other the orange gene. If a black male and an orange female mate, the result will be a half-black and half-orange female offspring-a calico. A black female and an orange male will also produce a calico female.

An ecosystem that has experienced a disruptive event, such as a volcanic eruption, will take time to recover from the effects of the disruption. The recovery process of an ecosystem is a complex, interconnected process between the biotic and abiotic components of a system. The recovery process that follows a disturbance varies depending on the type of disruption and the environment in which it occurs.

When a volcanic eruption occurs, it can release a great deal of ash and debris into the environment, and the effects can be devastating. The ash and debris can severely damage the terrestrial and aquatic ecosystems in the surrounding area, resulting in a loss of habitat, food sources, and other important resources. Additionally, the ash and debris can block sunlight and reduce photosynthesis, which can lead to a decrease in plant growth and a disruption of the food web.

True , This is the concept of axonal action potential propagation! Positive charges accumulate on subsequent regions of the membrane as a result of depolarization caused by an initiated action potential on one segment of the axon.

This local depolarization can cause an action potential to move along the axon by causing depolarization along the neighboring segment of the membrane.

Voltage-gated sodium channels open and close in milliseconds. As the cell membrane depolarizes, sodium channels open, allowing sodium ions to enter and further depolarize the membrane. This inward current causes the action potential to rise.
