Answer:
A high pressure system works downwards and brings with it good weather, while a low pressure system works upwards and brings bad weather. Due to the Earth’s rotation and friction on its surface, air currents are formed. When these currents move clockwise and out of the center, a space is formed at the center. The land quickly loses its heat whiles the water retains its warmth. That means the air over the water is warmer, less dense, and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

Many pine trees grow in the taiga, the largest habitat in the world. Using credible sources, such as NASA, research the typical climate conditions in the taiga. Explain why the structure of pinecones helps ensure successful reproduction in the taiga.
Answer:
Explanation:
Taigas have few native plants besides conifers. The soil of the taiga has few nutrients. It can also freeze, making it difficult for many plants to take root. The larch is one of the only deciduous trees able to survive in the freezing northern taiga.

Determine whether the statement is true or false, and why. “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated.”
A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
B. True
C. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This inhibits the rate of cell division decreasing it drastically.”
D. False, it should read “If a point mutation occurs in a Proto-oncogene gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Answer: A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Explanation: I already know this for a fact.
The statement “If a point mutation occurs in a tumor gene it can become activated. This allows the rate of cell division to increase unregulated" is false.
What is Point mutation?Point mutation may be defined as a method of genetic alteration that is caused by the substitution of a single nucleotide for another nucleotide in the DNA sequences. In this type of mutation, a single nucleotide base is altered through insertion or deletion from the sequence of DNA or RNA.
The above statement is false because if a point mutation occurs in a tumor suppressor gene it can become inactivated which terminates the expression of suppression of tumors.
And now the cell has the capability to grow unexceptionally with an irregular pattern. This allows the rate of cell division to increase unregulated and have a most potent threat of being infected with cancers.

Which is a non-Mendelian trait?
A. A trait controlled by many genes
B. A trait with a clearly dominant form
C. A trait controlled by one gene
D. A trait with two alleles
Answer:
The answer would be A.
Explanation:
Non-Mendelian traits are traits that are not passed down with dominant and recessive alleles from one gene. Examples of polygenic traits are hair color and height. ... Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
A non-Mendelian trait would be a trait that is controlled by many genes. The right option would be A.
Mendelian traits are traits that obey the principles of the Mendelian laws While non-Mendelian traits simply do not conform with the principles and laws of Mendel.
A trait that is Mendelian would have the following:
Show simple dominance or recessive formControlled by a single geneEach gene must have 2 alleles. The 2 alleles can be the same (homzygous) or different (heterozygous).Thus, a trait that is controlled by many genes is clearly a non-Mendelian trait.

Alternation of generation
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"Alternation of generation"
Alternation of generations is the type of life cycle that occurs in those plant and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.
Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.

Which of these statements about enzymes is true? Select
all correct answers.
a. Enzymes can help break chemical bonds.
b. Enzymes always change their shape when they bind
to a molecule.
c. Enzymes can break down a variety of different
substances.
d. An enzyme’s shape is related to the shape of the
substrate it binds to.
Answer:
b. Enzymes always change their shape when they bind to a molecule.
d. An enzyme’s shape is related to the shape of the substrate it binds to.
Explanation:
Enzymes are proteins that are secreted by special cells in living organisms. They are the organic catalysts of biochemical reactions.
The role of the enzyme in the enzyme catalyzed reaction is to bring reactants together on its surface so as to have better interactions.
Enzymes have the capability to fit the substrate into an induced fit position.
The process by which enzymes change shape in a reaction is called the induced fit.
This way an enzyme holds the substrate tightly for the reactions to occur.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.
Explanation:
An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.
