If the DNA sequence was a AGC what would the mRNA sequence be?
Answer:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem
Answer:
The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen
Explain whether the top or bottom layers would be the oldest layer of sedimentary rock.
explain your answer.
Answer:
Because sedimentary rock forms in layers, the oldest layer of undisturbed sedimentary rock will be on the bottom and the youngest on top. If the rock layers are bent, they may no longer be in order from oldest to youngest.
The bottom layer would be the oldest layer of sedimentary rock as sediments deposited earlier will be present at the bottom.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Why do the plant and animal cells SHARE some levels of classification?
Why are some levels of classification DIFFERENT?
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species .
1. The______ provides support and rigidity to cells allowing plants to stand upright.
plz help I need an answer
sclerenchyma
Explanation:
sclerenchyma is a suppprting tissue that gives the plants rigidity and support to make it stand upright. It is made up of scleroids and fibre.
Scleroids are small stonelike materials that are arranged in a way that helps the plants withstand force.
For example when rain falls and the wind's current is strong, it sways the plant from left to right but because of sclerenchyma, the plant can withstand the current and return to its normal position. But if the winds current or force is stroonger than that of the sclenchyma, the plant bends or breaks

Oceans formed when rainwater filled basins 3.8 billion years ago. ________ run into the ocean dissolving minerals like salt as they go. __________ leaves salt in the ocean, which is why the ocean is _________. Salinity has _______________, so the ocean is _______getting any more or less salty. Salinity makes water ____________ and contributes to currents.
Answer:
Physically erodes
Minerals
Dissolved
Crystals
Thicker
Minerals
Oceans formed when rainwater filled basins 3.8 billion years ago. Physical erosion runs into the ocean dissolving minerals like salt as they go. Minerals leave salt in the ocean, which is why the ocean is dissolved.
Salinity has crystals, so the ocean is thicker and getting more or less salty. Salinity makes water full of minerals and contributes to currents.
How oceans are formed?The oceans formed billions of years ago due to the condensation of water into rain which significantly filled the basins that ultimately direct the formation of the oceans. Apart from this, the continuous degassing of the interior surface of the earth is also responsible for this fact.
According to the context of this question, the salinity of the oceans depends on the number of minerals dissolved in it which contributes to the development of currents.

Which aspect of this experiment should be kept the same in all the other tests? Some students want to test different soils to find out which ones absorb heat the fastest. For the first test, they put 500 grams of sand in a beaker and put a thermometer in the sand. Which aspect of this experiment should be kept the same in all the other tests?
Answer:
Weight of the soil (500g)
Explanation:
According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.
In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.
This means that for the remaining soil being tested, 500g of each type of soil should be used.

Which organelle would be more developed in a cell of salivary glands?
Answer:
Lysosomes
Explanation:
Salivary glands are secretory cells, meaning they release substances into the extracellular environment. In the case of the salivary glands, they secrete water, electrolytes, mucus and enzymes, the components of saliva. Therefore, these cells have a very well-developed secretory system.
Lysosomes store secretory proteins and are important for keeping them sequestered from the rest of the cell, and eventually delivering them outside the cell.
What is the blending theory of inheritance? Why did Mendel question this theory?
Answer:
Blending Theory of Inheritance
Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory
The blending theory state that the inheritance of traits from two parents produces offspring with characteristics that are combination of the parents.
What is blending theory of inheritance?Blending theory of inheritance stated that, offspring is combination of characteristics of the traits from two parents. Blending inheritance was discarded after the general acceptance of the modern genetics.
Mendel noticed that plant in his garden were not blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height.
Therefore, Mendel question this theory. He wanted to know if there was different principle that could explain how the characteristics are inherited to the offspring from parents.

1.Water covers 70 percent of the earth's surface and supports life on the Earth. Explain the statement 2.Why do we need to manage our resources? { i need the answer before 4 pm please help!}
Explanation:
Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.
