Given the following evidence; which does not support the theory of Continental Drift?
NEED HELP ASAP
A) Location of ancient climate areas
B) fossils of plants and animals
C) continents are not currently moving
Eliminate
D. land features match up (like mountains) on different continents
The statement 'continents are not currently moving' does NOT support the theory of Continental Drift.
Continental drift is the hypothesis that posits the idea that continents moved (drifted) over geologic time on the surface of the ocean bed.According to this theory, all current continents were once joined together in a single supercontinent called Pangaea, which subsequently broke apart million years ago.The hypothesis of continental drift has been nowadays replaced by the idea of plate tectonics.In conclusion, the statement 'continents are not currently moving' does NOT support the theory of Continental Drift.

Name 1 hazard that has no forecast and 1 that does. Make sure you identify which is which.
Answer:
As other natural hazards, landslides are difficult to predict, and their forecasts are uncertain. The uncertainty depends on the poor understanding of the phenomena that control the slope failures, and on the inherent complexity and chaotic nature of the landslides. One that has forcast is volcanic eruptions.

Why does evolution only occur in populations and not to individuals?
Answer:
There are no evolving individual organisms. Evolve populations. Because people in a population vary, some are better able to survive and reproduce in the population given a specific set of environmental conditions.

In your own words, describe the base-pairing rules in any DNA molecule (Hint: Think about the BFF's)
Answer:
There are four different bases, each of which pairs with only another. Adenine (A) pairs with Thymine (T), and Guanine (G) pairs with Cytosine (C). This rule is universal to all DNA. A good way to remember is apples in the tree (adenine and thymine), cars in the garage (cytosine and guanine) (credit to the Amoeba Sisters)

What type of mutation has occurred in the following example? Original DNA Sequence ATC GGCT CITA GIG CIA Mutated DNA Sequence ATC GGCTA CT ACGC A
A) deletion mutation B) insertion mutation C) point mutation
The type of mutation has occurred in the example where the original DNA Sequence is ATCGGCTCTAGGCA and mutated to ATCGGCTACTACGC A is a C) point mutation.
What are insertion, deletion and point mutations?An insertion mutation is a type of point mutation that occurs when an extra base pair is inserted into the DNA sequence, a deletion leads to a short sequence and a point mutations lead to substitution in bases.
Therefore, with this data, we can see that insertion mutation leads to longer sequences while substitutions such as in this case are associated with changes in bases.

Need help. Will give brainliest. Answer all these questions.
Answer:
1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.
2. Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.
6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .

State the level of organization of euglena onion bulb and blood
Answer:
The correct answer is -
Euglena - single-cell organism
Onion bulb - organ
Blood - tissue (connective tissue)
Explanation:
The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.
Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.
The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.
Professor Danielle conducts an experiment on chloroplasts by deactivating several enzymes used for light-independent reactions. All components of light-independent reactions remain present. Would the light-dependent reactions proceed normally? Explain.
PLEASE HELP!!!!
Answer:
NO.
Explanation:
The process of reaction of CO2 with H20 in the presence of enzyme, chlorophyll and sunlight is called photosynthesis. It has two stages: It is referred to as light dependent stage when it occurs during the day and light independent stage when it occurs at night.
The primary enzyme likely to be deactivated by the Professor is ribulose bisphosphate Carboxylate Rubisco. This is the most important enzyme in plants that catalysis the fixation of Co2 with 5C- ribulose bisphosphate Carboxylase (RuBP) to form3C -Glycerite -3-phospate.(GP).
The GP is reduced by NADP with ATP to form Triose Phosphate (TP). This is the point of glucose production in plants,
The majority of the TP is used for RuBP, hexose phosphates for starch productions, fatty acid and glycerol for cell membrane. Amino acids are also produced from TP. This is known s Calvin Cycle.
If the enzyme Rubisco is deactivated, the above process cannot occur, thus the basic macronutrients and enzymes for the survival of plants for photosynthesis(light dependent stage) can not occur.
Answer:
No, the reaction will not take place normally.
Explanation:
Chloroplasts serves as a site for photosynthesis in plants. The process of photosynthesis which is essential for plants to make food occurs in two elaborate reactions namely:Light-dependent Reaction: Where chlorophyll takes energy from the sunlight and preserves it as chemical energyLight-independent Reaction: Which occurs after light-dependent where the energy is used from the light-dependent reaction to synthesize CO2 into carbohydrates. The Light-independent reaction occurs in the stroma in the presence of CO2; Ribulose-1,5-biphosphate ( RuBP) and an enzyme called (RuBisCO) Ribulose-1,5-biphosphate carboxylase/oxygenase which catalyzes the process. If Professor Danielle deactivates RuBisCO then the process of Calvin Cycle results in the end product of glucose by the process of fixation, reduction, and regeneration. The process will immediately cease depriving the plant of all the essential macronutrients produced as the end result of the Calvin cycle i.e., glucose, starch, amino acid, and fatty acid. This deprivation of nutrients will eventually affect the synthesis of ATP and formation of NADPH as food deprivation would affect the normal functioning of cell organelles.For more information:
