How are inherited characteristics passed on through generations?
Inherited characteristics are passed on through generations via the transfer of genetic information from parents to offspring. This genetic information is encoded in DNA, organized into genes, and carried on chromosomes.
How are inherited characteristics passed on through generations?Inherited characteristics are passed on through generations via the transmission of genetic information from parents to offspring. This genetic information is contained within molecules called DNA (deoxyribonucleic acid), which is located in the cells of organisms. The process of passing on inherited characteristics is known as heredity, and it occurs through the following mechanisms:
Genes and Alleles: Genes are segments of DNA that code for specific traits or characteristics. Each gene has different forms called alleles. These alleles can vary and determine the variations in traits among individuals.
Chromosomes: DNA is organized into structures called chromosomes. Humans have pairs of chromosomes, with one member of each pair coming from each parent. Each chromosome contains numerous genes.
Gamete Formation: In sexual reproduction, special cells called gametes (sperm and egg cells) are formed through a process called meiosis. During meiosis, the genetic material is shuffled and divided, creating gametes with a unique combination of genetic information.
Fertilization: When two gametes (sperm and egg) fuse during fertilization, they combine their genetic material, resulting in a new individual with a mix of genetic traits from both parents.
Dominant and Recessive Traits: Some traits are governed by dominant and recessive alleles. Dominant alleles mask the presence of recessive alleles. The combination of alleles determines the expression of traits in offspring.
Mendelian Inheritance: The principles of inheritance were first described by Gregor Mendel, and they involve the segregation and independent assortment of alleles during gamete formation and fertilization.
Genetic Variation: Sexual reproduction and the shuffling of genetic material during meiosis create genetic variation among offspring. This variation is essential for populations to adapt to changing environments over time.

A . .
two oceanic plates diverge.
B .
two continental plates converge
C . an oceanic and a continental plate diverge
D.
an oceanic and a continental plate converge
Largest mountains such as the Himalayas occur where two continental plates converge
The formation of mountains occurs due to the movement of plates, which are sections of Earth's crust. Moreover, this phenomenon happens when two plates converge or collide as this causes one plate to move beneath the other and creates elevations such as mountains.
Besides this, the formation of big mountains such as the Himalayas is mainly the result of continental plates converging (plates that form continents), for example, the Himalayas formed as the Eurasian and Indian plates collided.

What is Endoplasmic Reticulum? -,-
Answer:
It is a transportation system.
Explanation:
The endoplasmic reticulum is considered as the transportation system of the eukaryotic cell, and perform many important functions such as protein folding. Endoplasmic reticulum is a type of organelle which is made up of two subunits i.e. rough endoplasmic reticulum, and smooth endoplasmic reticulum. Endoplasmic reticulum performs a variety of essential cellular functions such as protein synthesis, processing, lipid synthesis, and calcium storage and its release in the body.
Answer:
So, the mitochondria are like the cell's power plant and the nucleus are the command center, then the endoplasmic reticulum (ER) is the cell's factory. This type of organelle is a packaging and storage facility. The ER is separated into two types – rough and smooth.
The rough ER looks like sheets of bumpy membrane. The bumps are just ribosomes attached to the organelle. The function of the rough ER is protein synthesis, (it's where the proteins are made). Ribosomes create amino acids that are built into proteins inside the ER. Some of the proteins are used by the cell, while others are packaged and sent out through the cell membrane for use elsewhere.
The smooth ER is a network of tubes attached to the rough ER. It is called smooth ER because it lacks ribosomes. The smooth ER is responsible for the production and storage of steroids and lipids, also known as fats. It also stores calcium ions used by muscle tissue.

Explanation:
Mutations that happen in sex cells during meiosis are able to pass onto offspring.
"Mutations in sex cells can be passed on to children." Therefore, option (A) is correct.
What is mutation?A mutation in a sex cell differs from a mutation in a non-sex cell in that mutations in sex cells can be passed on to children. Sex cells, such as eggs and sperm, carry genetic information that is passed on to the next generation during fertilization.
If a mutation occurs in a sex cell, it can be transmitted to the offspring and can potentially affect the genetic makeup of future generations. On the other hand, mutations in non-sex cells, such as skin cells or liver cells, cannot be passed on to offspring because they do not contribute to the genetic material of the next generation.

a. The intermediate stages in the evolution of a complex character had no fitness advantage.
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
c. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
e. Usually a single mutation in one gene leads to the simultaneous appearance of the complex character.
Answer:
b. Often the initial stage in the evolution of a complex character was an adaptation to some unrelated selection pressure.
d. Phylogenetic analysis using cladistics can help reveal the sequence leading to the evolution of a complex character.
Explanation:
The evolutionary developmental program of complex characters can be analyzed by examining synapomorphies, i.e., by examining shared, derived characters common between an ancestor of a given taxonomic group and its descendants. Synapomorphies are able to create evidence for historical relationships between closely related organisms. Moreover, cladistics is a method used to categorize species/taxa into groups called 'clades' based on arranging organisms with similar traits, which can provide useful information on the evolutionary history of complex traits in different species/taxa. In phylogenetics, the analysis of complex characters involves two different stages: 1-character analysis and 2-cladistic analysis. Homology refers to structures that look similar because they were inherited from a common ancestor (i.e., they have a common origin); whereas characters are considered as parts of transformation series. In cladistics, characters used for inferring phylogenetic relationships are considered as hypotheses of homology that are subject to tests of similarity. In consequence, such characters can provide useful information on the evolutionary history of complex traits.

When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.
Answer:
positive pressure
Explanation:
Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.
Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.
