what is the cause and effect of tRNA muation
Answer:
the effect of tRNA is that it will give mutations and they are linked to diseases. The mutations will cause changes in the gene.
What is the function of the Calvin cycle?
I’m not sure someone helppp!!! Quickly please
Answer:
its the the first option
Explanation:
This is because plants fix carbon dioxide from the atmosphere through photosynthesis. They produce sugar for food from the CO2.
Answer:It would be A i believe
Explanation: The enzyme RuBisCO is an organic compound that incorporates carbon dioxide. The organic molecule is reduced in stage 2. RuBP, the enzyme that begins the cycle, is regenerated in stage 3 so that it can begin the cycle. In short, fixing six carbon atoms from CO2 requires six turns of the Calvin cycle.

What is evolution?
This is the process of change in the characterstics of a species over several generations.

b) Explain how a farmer could use selective breeding to breed pigs which are very docile in
nature.
Answer:
The correct process would be :
Choose pigs that are the most docile to breed from.
In the next generation only choose docile pigs to breed from.
Carry this on for many generations until all the pigs in the herd are docile.
Explanation:
Selective breeding is the process of breeding specific parents to get specific of desired characterstics in offspring organism or crops. The selective breed takes place by selecting. It is a process that used for many years.
breeding pigs with docile characteristics would involve:
Choose pigs that are the most docile.
Breed these pigs to produce docile pigs
In the next generation only select or choose docile pigs to breed from.
repeat the process for many generations until all the pigs in the herd are docile.

What advantage does cross pollination have over self-pollination?
It assures that there is genetic variety within each plant species.
It allows a plant to have both male and female flowers.
It allows a plant to fertilize itself.
It ensures that all offspring will be identical.
Answer:
It assures that there is genetic variety within each plant species.
Explanation:
When a plant does self-pollination it has only it's own genetic pool.
Answer:
Its It assures that there is genetic variety within each plant species.
Explanation:
All cells have DNA.

false
Answer:
True
Explanation:
A woman has three children, aged 4, 6 and 9 years.
Why are the children not genetically identical?
Answer:
Because she gave birth to them differently and they are not twins so they will not be identical but will have some genetic traits in them
Select all that apply Choose all features that confined the green algal ancestors of plants to water. Multiple select question. Higher levels of UV light on land Less water availability in a terrestrial environment The inability to produce chlorophyll in a high oxygen environment More predators in land-based ecosystems
Answer:
Higher levels of UV light on land
Explanation:
The algae began to appear because of the presence of ultraviolet light that was emitted by sunlight, this generated the increase in temperature of the waters, therefore under the glaciers the perfect climax was formed so that these could begin to emerge phenomena, not excessive sunlight, the great presence of oxygen, is what led to the appearance of these algae.

What makes proteins with different functions differ from each other?
the order of the amino acids in them
the bonds that join the monomers
the amount of carbon, oxygen, and hydrogen contained in them
the types of fatty acids in them
Answer:
the order of the amino acids in them
Explanation:
Each protein has its own unique sequence of amino acids and the interactions between these amino acids create a specify shape. This shape determines the protein's function, from digesting protein in the stomach to carrying oxygen in the blood.

What proof do you know have that living things are similar when viewed through a microscope?

Whether living or non living: When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.
Explanation:
Where are centrosomes (microtubule-organizing-centers) located in an animal cell?
Answer:
The centrosome, cytocenter, or cell center is unique to animal cells. It is close to the nucleus and is considered an organizing center for microtubules.
Explanation:
The centrosome is a nonmembranous organelle, present in all dividing animal cells. It is located near the nucleus, often surrounded by the dictyosomes of the Golgi apparatus. The structure consists of an interior zone where the diplosome appears, formed by two centrioles arranged perpendicular to each other. The microtubules emanating from the centrosome end up in the pericentriolar material, not the centrioles, and it is the pericentriolar material that initiates the assembly of the microtubules. Therefore, the main function of the centrosome is to nuclear and anchor the microtubules.

Explanation:
Energy in biology falls into two categories. Kinetic energy (aka cellular work) includes solute
transport, motion, and endergonic chemical reactions. Potential energy is the energy of position and
is an important tool to store energy in biology. Potential energy in biology includes covalent bonds
and chemical gradients. Which of the following is evidence of the potential energy of covalent
chemical bonds?
a
Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
All of the other choices are evidence of the potential energy of covalent bonds.
O Light and heat are released when cellulose (wood) is burned.
Exergonic hydrolysis of ATP powers motor proteins.
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.
how does evolution occur ?
Explanation of Evolution:
Evolution refers to a gradual change in DNA. It can also occur by natural selection when certain traits are created by mutations that help an organism survive or reproduce.
Answer:
So technically, evolution is when an organism gradually changes over time during reproduction.
Which of the following distinguishes scientific law from scientific theory?
A law is supported by a substantial body of evidence.
A law explains a set of related phenomena.
A law is often non-mathematical.
A law is consolidated by repeated testing of a phenomenon.
Explain the difference between the theory of general relativity and the law of gravity.
Answer:
Explanation:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory.
The answer is IN FACT:
A law is consolidated by repeated testing of a phenomenon.2. Interpret Graphs As you move up the y-axis, is the rate of photosynthesis
increasing or decreasing? As you move along the x-axis to the right, is the light
intensity increasing or decreasing?
Answer:
It depends on the graph movement.
Explanation:
If the light intensity is present on the x-axis and the rate of photosynthesis is located on the y-axis, then both the rate of photosynthesis and intensity of light are increasing because the graph moves upward which means the rate of photosynthesis increases with the increasing of light intensity. So if you moves from upward to downward, the rate of photosynthesis decreases with the increasing of light intensity.

Answer:
The question is incomplete , as the options are not given. Here are the options.
A. Hyperplasia
b. Metaplasia
C. Dysplasia
D. Anaplasia
The correct option is b.
Metaplasia
Explanation:
This because metaplasia is the process where by one mature cell can be replaced by another cell in the body. This is a reversible replacement that take place in the cell of the body. In this kind of replacement, a less differentiated cell replaced the mature cell. It occur when normal columnar ciliated epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells.
