What causes oceanic plates to move?
Answer:
The main driving force of plate tectonics is gravity. If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle. ... However, convection also drives plate tectonics.

Explanation:
In a flower, the anther is attached to filament. What advantage does the filament provide to the anther?
A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
B. The filament provides the anther with nutrients to produce pollen grains.
C. The filament protects the anther from harsh sunlight and insects.
D. The filament produces a sticky surface to allow the anther to capture pollen.
The correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.
Explanation
The filament of a flower is the sterile part of the stamen (male organ of the flower) that is located just below the anther. Its function is structural to hold the sling so that it is accessible to insects. The filament is usually cylindrical and fine. Therefore, the correct answer is A. The filament elevates the anther to allow for easier transport of pollen by wind or insects.

Imagine you were an animal that lived in the tundra. What are three adaptations that would help you survive by either finding food or avoiding being eaten?
Answer:
Animal Adaptations in the Tundra Biome
Animals need shelter and insulation in the Tundra. The animals here tend to have thicker and warmer feathers and fur. Many of them have larger bodies and shorter arms, legs and tails which helps them retain their heat better and prevent heat loss.

Answer:
Stamens are the male reproductive organs of flowering plants. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal.May 6, 2004

A group of white, grey, and black rabbits lives in Alaska, where there is usually snow on the ground. Wolves that hunt the rabbits end up mostly catching ones with grey and black fur. As a result, white rabbits become more prevalent in the population. This is an example of:
Answer:
Directional selection
Explanation:
Natural selection is the process by which environment selects from a population of organisms which individuals are better suited and adapted to that environment. There are three types of natural selection namely: directional selection, disruptive selection and stabilizing selection.
Directional selection is the type of natural selection in which only one extreme (phenotype) of a population is favored over the other extreme and intermediate individuals. This is the case in the example given in the question where among a group of white, grey, and black rabbits that lives in Alaska, environment selects the white rabbits (one extreme) from wolf predation, hence, causing the white rabbit population to increase and be favored.

Where should blood samples be taken for postmortem toxicological analysis?The femoral vein should be punctured with a 10 mL or 20 mL hypodermic syringe for the greatest results. To maximise specimen volume before sampling, the leg shouldn't be rubbed. Vitreous fluid is frequently taken during forensic postmortem examinations for toxicological study.

g The transcriptome of humans shows that (select all that apply): Group of answer choices Approximately 2% of the genome is transcribed Protein coding genes represent the vast majority of the total genome sequence that is transcribed A large number of non-protein coding sequences are transcribed Total transcription changes over time in embryonic stem cells
Answer:
- A large number of non-protein coding sequences are transcribed
- Total transcription changes over time in embryonic stem cells
Explanation:
The transcriptome refers to the totality of RNA molecules (i.e., mRNAs, microRNAs, long noncoding RNAs, etc.) that are synthesized in a given cell type/tissue/development stage. The analysis of human transcriptome has been essential to discover genes and non-coding RNAs expressed at each developmental stage, as well as genes whose expression is associated with human diseases. Next-Generation Sequencing (NGS) information showed that more than 90% of the human genome is transcribed into RNA, especially non-protein-coding sequences (i.e., non-coding RNAs). Moreover, information on the human transcriptome evidenced that global transcription changes occur in pluripotent embryonic stem cells, and these changes are mainly associated with the expression of chromatin-remodeling genes as well as genes responsible to encode the components of the general transcription machinery.
what’s a characteristic of precipitation
Answer:
Precipitation is liquid or solid water falling from clouds to the Earth's surface or formed on different bodies as a result of atmospheric water vapor condensation. Precipitation can be liquid, solid, or mixed. Liquid precipitation includes rain and drizzle.
What is compensation point ?
➜ When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point.
The rate of liberation of O2 during photosynthesis is equal to the rate of liberation of CO2 during respiration.Thus, there is no net uptake of gases from the environment.Compensation point is usually reached at dusk and down and on a cloudy day.. What cellular structure or characteristic seems to be generally true of organism that use photosynthesis?
Answer:
Photosynthesis in plants occurs in specialized organelles called chloroplasts.chloroplast are found in plant leaves and contains the pigment chlorophyll. the green pigment absorbs light energy needed for photosynthesis to occur.

A tissue is composed of a group of
Answer:
Tissue is a group of cells that have similar structure and that function together as a unit. primary types of body tissues include epithelial, connective, muscular and nervous tissues. Epithelial tissues form the covering of all body surfaces , ine body, cavities and hollow organs, and are the major tissues in glands.
A tissue is composed of a group of cells that are determined to play a specific function. The Cytoplasm is a dense gel-like material that is filled within the cell.
What is Cell theory?Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.
Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.
Therefore, each of the above-given term is justified above.

Answer:
Actually the correct answer is C. The energy used Per Capita but good try plz mark as brainiest I really need it.
Explanation:
The production of energy plants and combined heat and power plants, fewer losses in transmission, distribution, and transformation, and own usage by heat and power plants. It is expressed as the amount of electricity consumed per person (kWh), divided by the midyear population. Thus option C is correct.
What determination of a community’s quality of life?Societies are impacted by energy in both positive and harmful ways. It is advantageous for humans to have access to plentiful, affordable, secure, safe, and clean energy. However, the production, distribution, and use of energy can have a severe impact on a society's health, ecology, and economy.
Energy use is inextricably linked to population growth and quality of living. Energy consumption in 2040 may be maintained at 2010 levels by limiting overconsumption. Future energy demand is only little impacted by limiting population increase. Reducing social disparity improves quality of life while using little energy.
Therefore, the energy used per capita.

As water temperature __________ the amount of O2 dissolved in water _____.
Answer:
Explanation:
As water temperature increases, the amount of O2 dissolved in water decreases.
The graph looks something like this (though not exactly. It just has the same sort of shape.)
During a hot, dry day, plants close their stomata to prevent water loss. When scientists replicate this environment in an experiment, they observe that over time, the plants stop producing oxygen.
Why does oxygen production stop?
