timeline of genetics
Answer:
Explanation:
5000 BC
Demonstrating some understanding of inheritance, humans worldwide begin to selectively breed more useful varieties of livestock and crops, including wheat, maize, rice and dates
400 BC
Greek philosophers contemplate the mechanisms of human inheritance. Aristotle believes that traits acquired during life, such as injuries, can be passed to offspring. He also develops the theory of “pangenesis”, which attempts to explain how these traits are transmitted via particles called “gemules” to the reproductive cells
1859
Charles Darwin, himself a proponent of pangenesis, publishes On the Origin of Species – his explanation of evolution by natural selection. Darwin provides a plethora of evidence on how valuable traits become more common in a population, but does not provide any explanation for the mechanism of transmission of these traits
1866
Augustinian monk Gregor Mendel publishes his work on the patterns of inheritance in pea plants. His meticulous studies mark the birth of modern genetics. Mendel’s findings escape the notice of other researchers for over three decades
1882
Chromosomes are discovered by German biologist Walter Fleming, and named with the Greek prefix meaning “colour” because they become stained when cells are dyed
1902
Mendel’s research is rediscovered by botanists in 1900. US and German cell biologists then independently notice the link between Mendel’s “units of inheritance” and chromosomes. They conclude that hereditary information is contained within chromosomes
1905
The term “genetics” is created by British biologist William Bateson. The terms “gene” and “genotype” surface in 1909.
Sex chromosomes are discovered following work on butterflies and beetles
1910
US scientist Thomas Hunt Morgan is the first to discover a sex-linked trait, while studying the fruit fly Drosophila. The trait for eye colour, on the X chromosome, is also the first gene to be traced to a specific chromosome
1925
Studies show that X-rays can induce mutations in the genetic material
1944
A trio of US geneticists revisit work from the 1920s and prove that, in bacteria, DNA is the hereditary material, and not protein as was previously suspected
1951
Clear X-ray diffraction images of DNA are captured for the first time by British researcher Rosalind Franklin
1953
Building on Franklin’s work, biochemist James Watson and biophysicist Francis Crick at Cambridge University, UK, determine the now famous double-helix structure of DNA. They are awarded a Nobel prize in 1962 for their efforts.
1961
Crick and South African geneticist Sydney Brenner report that trios of DNA bases – called nucleotides – each hold the instructions for one of the 20 amino acids that combine to form proteins
1973
US researcher Herb Boyer uses enzymes to cut DNA and splice it into bacterial plasmids, which then replicate producing many copies of the inserted gene. This heralds the dawn of genetic engineering
1978
Genetically modified bacteria produce the hormone insulin
1983
The gene for an inherited disorder (Huntington’s disease) is mapped to a chromosome for the first time
1986
Kary Mullis in the US develops the Polymerase Chain Reaction (PCR), which allows researchers to produce many millions of copies of DNA molecules in just a few hours
1990
The international Human Genome Project begins, with the goal of sequencing the entire human genetic code
Gene therapy is used successfully for the first time, to treat a four-year-old girl with the rare hereditary immune disorder adenosine deaminase deficiency
1994
FlavrSavr tomatoes, genetically modified to have a long shelf-life is the first GM product to go on sale in the US. GM tomato puree goes in sale in the UK in 1996
1996
Baker’s yeast is the first (non-viral) genome to be completed, followed by the worm Caenorhabditis elegans in 1998 and then the plant Arabidopsis and fruit fly Drosophila in 2000
2000
Completion of the draft human genome is jointly announced by US firm Celera Genomics and the Human Genome Project (an international public consortium). The full sequence – comprising 30,000 to 40,000 genes – is completed in 2003
2003

Which TWO cellular structures are directly involved in protein production in the cells of both grass and white-tailed deer?
А
Lysosomes
B
Ribosomes
с
Centrioles
D
Central vacuole
E
Rough endoplasmic reticulum
Answer:
The correct answer is - option B. ribosome and option E. rough endoplasmic reticulum
Explanation:
The rough endoplasmic reticulum and ribosome are directly involved in the protein synthesis as ribosome helps in the process of translation and rough endoplasmic reticulum helps in editing, modifying, and packaging of the protein formed.
These both are present in eukaryotic cells such as white-tail deer and plants like grasses, together as rER have many membrane-bound ribosomes.
Thus, the correct answer is - option B. ribosome and option E. rough endoplasmic reticulum

Wolves prey heavily on beavers in a temperate forest ecosystem. The diet of beavers consists of the leaves, branches and bark from trees, as well as many types of aquatic vegetation. In this relationship, what is the role of the wolves? A producer B decomposer C primary consumer D secondary consumer
Answer:
In this relationship , the role of wolves is as Secondary Consumers .
Explanation:
A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.
All the green plants, for example.A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).
Fungi and bacteria that derive their nutrients from dead plant or animal matter are examples of decomposers.PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.
Insects, mice, and deer are common examples of this type of product.SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.
You can find secondary users, such as dogs , cats, moles, and birds, in temperate areas , for example. Foxes, owls, and snakes are other examples. Examples of secondary consumers that receive their energy from primary consumers by scavenging are wolves, crows, and hawks.In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .
Hence, the correct answer is OPTION D.

Discuss why liquid water can exist on Earth.
Imagine that you are given 25 germinating pea seeds that have been placed in 5M hydrochloric acid for five minutes. You place these seeds after you rinse them off, in a respirometer at the end of the five minutes and collect data. Predict the rate of oxygen consumption for these seeds and explain your reasoning.
Answer:
In the respirometer, it will be present no significant values of oxygen from the respiration process. The acid can denature proteins in a non-functional shape.
Explanation:
The pH of the solution will be considerably low in order to the proteins to work normally. In this case, the polarization of sites in the protein will cause a completely denaturation.
A normal pH is essencial for the best working coefficient of enzymes an proteins in general as well as temperature.

how can you use the electron configuration to determine the number of valence electrons
Here, we are required to explain how the electronic configuration can be used to determine the number of Valence electrons.
The algebraic sum of electrons in the highest energy level in an electron configuration is the number of Valence electrons of the element.Valence electrons simply refers to electrons present in the outermost shell of an element.
Valence electrons simply refers to electrons present in the outermost shell of an element.The electron configuration is a representation of the arrangement of electrons in the atomic orbitals of an element.
The number of electrons present in the outermost shell as evident from the electron configuration can be used to determine the Valence electron in the elements.Fir instance: the electron configuration of potassium; 1s² 2s² 2p⁶ 3s² 3p⁵
The algebraic sum of electrons in the energy level 3 therefore is the number of Valence electrons.

O deltas
O gullies
O flood plains
O stalactites
Gullies are a feature that may form as a result of erosion related to runoff. It may produce the transfer of water from fields to adjacent land.
What is runoff erosion?Runoff erosion is a natural process that produces the transfer of water from fields to adjacent land.
The runoff may lead to erosion because the eroded material in the soil can be deposited a significant distance away.
This process (runoff related to erosion) occurs when there is more water or any other substance (for example, pesticides) than the land/soil can absorb.

Explanation:
When snow covering the ice sheet blow away, there is an increase in oxygen bubbles trapped under the ice. Explain why this occurs
Answer:
Impurities are trapped between layers of ice over the years.
Explanation:
As time goes on, many chemical impurities and gases are trapped between deposits of ice that form over the years in extremely cold regions such as Antarctica.
When the snow covering these layers of ice are removed, the gases trapped underneath are released and more oxygen dissolves in the ice and more bubbles are observed.
