which type of traits are responsible for evolution?
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

The Central Dogma of Biology describes a two-step the process of DNA-RNA-Proteins. Which process is being observed in the diagram below?
The process shown in the given image is transcription. The correct option is 3.
What is transcription?In genomics, transcription is the process of creating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.
The process of copying a segment of DNA into RNA is known as transcription.
Messenger RNA is created when segments of DNA are transcribed into RNA molecules that can encode proteins. Other DNA segments are copied into RNA molecules known as non-coding RNAs.
The process of copying DNA to RNA is known as transcription, and the process of using RNA to make proteins is known as translation.
Thus, the correct option is 3.

Why do plants of the fields become yellowish?
Answer:
Poor drainage or improper watering
Explanation:
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.

WILL GIVE BRAINLISTTTT!!!! In what ways are mechanical, chemical and biological weathering responsible for changes in our environment?
Answer:
Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze.

Describe how a vaccination prevents disease in the individual who receives a vaccination.
Answer: Vaccines give you immunity to a disease without you getting sick first. They are made using killed or weakened versions of the disease-causing germ or parts of the germ (called antigens). For some vaccines, genetic engineering is used to make the antigens used in the vaccine.
Explanation: Vaccines greatly reduce the risk of infection by working with the body's natural defenses to safely develop immunity to disease.
state two functions of the onjective lens on a microscope
Answer:
please give me brainlist and follow
Explanation:
In microscopy, the objective lenses are the optical elements closest to the specimen. The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens. Objective lenses are the most complex part of the microscope due to their multi-element design.
Which scenario would result in a decrease in population size, or a negative population growth?
Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate
Answer:
The third situation has the lowest amount of people with 0.
Explanation:
In this situation,
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate. Population growth = 14
In this one,
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate Population growth = 2
For this one,
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate Population growth = 0
Last one,
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate Population growth = 2.

Dino and his family live in a community where people just throw their garbage anywhere. Recently, Dino was hospitalized due to diarrhea. His sister is now afflicted with dengue, and his father has lost his job because of tuberculosis. On space provided, discuss the possible causes of the health problems in Dino's family. What can be done to alleviate their situation? I NEED IT RIGHT NOW PLS! I cant find the subject Science cuz this is in science
Answer:
The main measure that must be taken to alleviate this situation is the proper disposal of garbage in the community in which Dino lives.
Explanation:
Inadequate disposal of garbage can cause a series of very serious illnesses and accidents to the entire community, which reinforces the need for all residents of a community to promote the proper disposal of waste. This is not happening in the community where Dino and his family live.
The inadequate disposal of garbage can contaminate the water and food of the community, causing diarrhea in Dino. This garbage also caused the accumulation of standing water, allowing the dengue mosquito to develop and infect his sister. In addition, garbage has created a suitable environment for maleficent microorganisms, such as the bacteria that causes tuberculosis.

1. Explain the justification for and the circumstances surrounding the internment by the US government of Japanese Americans during World War II.
Answer:Under the Executive Order, some 112,000 Japanese Americans—79,000 of whom were American citizens—were removed from the West Coast and placed into ten internment camps located in remote areas. Japanese Americans were given only a few days' notice to report for internment, and many had to sell their homes and businesses for much less than they were worth. In so doing, they lost much of what they had accrued in the course of their lives.
The camps—like the one at Manzanar, California, located at the foot of the Sierra Nevada mountains—were surrounded by fences, barbed wire, guard towers, searchlights and machine guns. Families incarcerated in the camps lived in uninsulated cabins or converted stables. They occupied their enforced idleness by organizing schools and camp newspapers, by running barber or beauty shops, and more. A small number were cleared for work outside the camps. Fred Korematsu was an American-born twenty-three-year-old welder of Japanese descent living in the San Francisco Bay area. In May 1942, he was arrested for failing to comply with the order for Japanese Americans to report to internment camps.
With the help of the American Civil Liberties Union, Korematsu sued on the grounds that as an American citizen he had a right to live where he pleased.
But in a 6-3 decision in Korematsu v. United States the Supreme Court ruled that interning Japanese Americans during the war for purposes of "military necessity" was constitutional.

The correct answer about the human genome project is Tracing how aboriginal people spread across Australia as it helps in the human genome project.
We gift an Aboriginal Australian genomic collection acquired from a 100-year-vintage lock of hair donated with the aid of using an Aboriginal guy from southern Western Australia withinside the early twentieth century.
We display that Aboriginal Australians are descendants of early humans. We additionally locate proof of gene glide among populations of the 2 dispersal waves previous to the divergence of Native Americans from contemporary-day Asian ancestors. Our findings assist the speculation that gift-day Aboriginal Australians descend from the earliest people to occupy Australia, probably representing one of the oldest non-stop populations out of doors Africa.What is HGP?The Human Genome Project became the worldwide studies attempt to decide the DNA collection of the complete human genome.
