Answer:
True.
Explanation:
Scientific models are important to represent natural phenomena but they must be 100% real in order to know right and provide correct information about natural phenomena. If they are not 100 % real so they provide false or incorrect information about the natural phenomena. If they are 100% right then they will increase the knowledge and understanding of students so it must be 100 % real to gain complete information about natural phenomena.
What do you think the color of the pea plants has to do with genes?
Answer:
According to Mendel Gregor, he analyzed two plants can make a different offspring. It depends on the alleles. I hope this helped!
Explanation:
Answer:
The instructions for making a pea plant are found in its genes. Each gene has the instructions for one small part of the pea plant. There is a gene that determines the color of the peas the plant will produce. These genes can come in all different versions.

Read the following scenario to answer the following question. Avian influenza is a viral infection with few damaging effects that naturally occurs in wild birds. However, avian influenza is highly contagious and can quickly kill domesticated birds. Some human influenza viruses are similar to the avian influenza. People infected with avian influenza develop typical flu symptoms (fever, cough, muscle aches). However, symptoms may become more severe and life-threatening. If avian influenza evolves into a form that is easily transmissible from person to person, a global pandemic of widespread human death might occur. Which cells would be active during an immune response to a viral infection
Answer:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.
Explanation:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.

How do cancer cells differ from normal cells? Select all that apply.
A
they do not stop at checkpoints
B
they condense their DNA into chromosomes for cell division
C
they have uncontrolled growth
D
they go through the S phase
Answer: A and B
Explanation:
Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth. So, options A and C are correct.
What do you mean by Cancerous cells?Cancerous cells may be defined as an abnormal cell that doesn't follow the regulations of the cell cycle. They get multiply at a rapid speed.
Normal cells follow a typical cell cycle. They grow, divide and finally die. But cancer cells do not follow the cell cycle, they do not undergo apoptosis, and they continuously multiply at a rapid pace.
Therefore, Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth.

If brown hair is represented by the allele "B" and blond hair is represented by the allele "b" then what must the genotype(s) be of someone who has brown hair?
Answer:
Bb or BB
Explanation:
since brown hair was the dominant allele it only has to have one big B to serve as a heterozygous dominant trait. Therefore, the person has brown hair. If you were looking for blond hair it would have to be bb because it is a recessive trait and you need two recessive traits to make up a certain genetic trait.

Beginning around 1750,the global human population began to grow at much faster then it had in the years before this time.What caused this to change in the population growth rate?
Answer:
The cartogram is made up of squares, each of which represents half a million people of a country’s population. The 11.5 million Belgians are represented by 23 squares; the 49.5 million Colombians are represented by 99 squares; the 1.415 billion people in China are represented by 2830 squares; and the entire world population of 7.633 billion people in 2018 is represented by the total sum of 15,266 squares. It started in 1798, to the 1800. This period is when the human population began to grow at a faster rate then any other time in history. The answer is 300 years ago.
Explanation : Births - usually measured using the birth rate (number of live births per 1,000 of the population per year). Deaths - usually measured using the death rate (number of deaths per 1,000 of the population per year). Migration - the movement of people in and out of an area.

The atoms of certain element each contain 36 protons and 8 valence electrons. Which statement correctly identifies this element and describes its chmical reactivity?
Answer:
This question lacks options, the options are:
A The element is krypton, Kr, and it is not very reactive.
B The element is chlorine, Cl, and it is highly reactive.
C The element is krypton, Kr, and it is highly reactive.
D The element is chlorine, Cl, and it is not very reactive.
The correct answer is A
Explanation:
An atom is identified by its atomic number, which is the number of protons it contains. In this question, it is said that the atoms of a certain element each contain 36 protons. Using the periodic table, the element with atomic no. 36 is KRYPTON.
Also, Krypton posseses 8 valence electrons in its outer shell. In accordance to the octet rule, Krypton has no further need to engage in any chemical reaction to fill its electron shell because it is already filled (8 valence electrons). This accounts for the reason Krypton belongs to "Noble gases" and very unreactive.
I need help 1 more time How does the Sun manage to maintain an environment in its core that is conducive to nuclear fusion? I'll mark 1 more Brainliest so plz I really need this done before Monday
Answer:
Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.
