Explanation:
When we say that DNA replication is semiconservative, we mean that: None of the other answer options is correct. only half of an organism's DNA is replicated during each cell division. parental DNA stays in the parent cell and daughter DNA ends up in the daughter cell. when DNA is replicated each new double helix contains one parental strand and one newly synthesized daughter strand.
Answer:
each new double helix contains one parental strand and one newly synthesized daughter strand, is the correct answer

Be specific about how invasive species impacts the environment here in Hawaii.
What will happen in the future if this issue is not addressed? Why does this issue need to be addressed?
Answer:
Terrestrially, invasive species are proving to be a major difficulty in Hawaii because the islands lack many natural predators of invasive animals. Invasive predators often move to the top of the food chain and disrupt prey populations, particularly small mammals, birds, insects, and plants. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Explain why scientists classify organisms and how scientists classify species.
Answer:
-Scientists classify living things to organize and make sense of the incredible diversity of life.
-they do on the basis of shared physical characteristics. They place them in a hierarchy of groupings, beginning with the kingdom animalia and proceeding through phyla, classes, orders, families, gender and species.
Which of these is not a direct function of mitosis in humans?
O development from embryo to adult
O reproduction to produce the next generation
O repair of damaged tissue
O growth
Answer:
O reproduction to produce the next generation
Explanation:
Meiosis is responsible to reproduction (not mitosis). The rest of options are for mitosis.
The one that is not a direct function of mitosis is reproduction to produce the next generation. The correct option is B.
What is mitosis?Mitosis is a type of cell division in which one cell (the mother) divides to produce two new genetically identical cells (the daughters).
Mitosis is the process by which the DNA of the cell's nucleus is divided into two equal sets of chromosomes in the context of the cell cycle.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Thus, the correct option is B.

A-T-T-C-G-G-A-C-T-A, is paired with this complementary strand: This allows A and T to pair and C and G to pair. Each base hydrogen-bonds to its complementary base.

Answer:
I assume you mean photosynthesis.
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Mendel crossed pea plants dominant for two different traits (tall and green pods) with pea plants recessive for those same two traits (short and yellow pods). This cross resulted in pea plants that had combinations of all four traits (tall with green pods, tall with yellow pods, short with green pods, and short with yellow pods). Which law of inheritance best describes why this happens
The law of inheritance that explains such a pattern of trait inheritance is the law of independent assortment of genes.
Law of independent assortmentThe law states that characters are inherited independently from one another. In other words, the inheritance of trait 1 is totally independent of the inheritance of trait 2.
There are several exemptions to the law of independent assortment of genes. There have been cases of linkages and gene interactions such as pleiotropy.
