advantages and dis advantages of asexual reproduction in plants
Explanation:
Advantages Of the asexual reproduction
The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?
The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.
Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.
Disadvantages Of Asexual Reproduction
Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.
Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.
The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.
The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

Describe the different theories of Oxidative Phosphorylation
Answer:
The Chemical Coupling:
A coupling reaction in organic chemistry is a general term for a variety of reactions where two fragments are joined together with the aid of a metal catalyst.
The Conformational Coupling:
The basic idea, as originally proposed by Robin Irvine, is that stimulation of the IP3 receptor (IP3R) by store emptying induces a conformation change that is transferred to the channel in the plasma membrane through a direct protein-protein interaction (3)
The Chemiosmotic Coupling
For approximately twenty years, it has been generally agreed, in accordance with the chemiosmotic theory, that the coupling of electron transfer reactions to ATP synthesis is mediated by a proton electrochemical gradient, often alternatively called a protonmotive force, generated across these membranes by electron
because im too lazy to look them up what are the definitions of:
^Air mass
^Front
^Cold front
^Warm front
^Occluded front
^Stationary Front
^Low pressure system
^High pressure system
^Coriolis effect
(please put in the same format, ty :D)
Answer:
Explanation:
Air Mass: a body of air with horizontally uniform temperature, humidity, and pressure.
Front: the forward edge of an advancing mass of air.
Cold Front: the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
Warm Front: the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system.
Occluded Front: a composite front produced by occlusion.
Stationary Front: a front between warm and cold air masses that is moving very slowly or not at all.
Low Pressure System: A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.
High Pressure System: A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure.
Coriolis Effect: an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.
AUG is the start codon, and UAG, UGA, and UAA are the possible stop codons.
The code on a human mRNA reads AUGCCCUUUAUGGGGUAA.

Which statements are true about this sequence?
Select all that apply.
Protein synthesis cannot start because there is no start codon.
The protein will have only four amino acids.
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Answer:
The correct answer is -
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Explanation:
In protein synthesis, there are mRNA codons made up of the three bases known as triplet codons that form a specific amino acid during translation. There is a specific codon known as the starting codon that is AUG present at the beginning of almost every protein sequence and code for the methionine amino acid. UAG, UGA, and UAA are the stop codons if present at the end of the mRNA sequence and if any of these stop codons are present at the end of the sequence they do not produce any amino acid.
In this case, the mRNA sequence having 6 triplet codons AUG CCC UUU AUG GGG UAA where the first AUG is a start codon and code for the methionine and UAA is a stop codon and do not code for any amino acid therefore, the protein would carry only 5 amino acid and as there are two AUG so it has two methionine.
Answer:
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.

O B. Biomass energy uses a turbine to produce electricity.
O C. Biomass energy is a renewable energy source.
O D. Biomass energy is unavailable in the United States.
Answer: A
Explanation: ap3x
Biomass energy is different from wind energy, as biomass energy emits a large volume of greenhouse gases. The correct option is A.
What is biomass energy?Biomass energy is the energy that is produced by the living organism. This energy is produced by decaying organic matter or burning organic matter.
This biomass energy is produced by burning of matter, which produces pollution, but wind energy does not produce energy.
Thus, the correct option is A. Biomass energy emits a large volume of greenhouse gases.

O decomposition
sun
O combustion
O consumers
Answer:
B. Sun.
Explanation:
The carbon cycle can be defined as the cycle in which carbon atoms travel from the atmosphere to earth and back to the atmosphere. As carbon is the source through which all life on earth exists.
The source of the carbon cycle is solar energy. During the process of photosynthesis, it is the sun that plays an integral role in taking carbon dioxide from plants.
Therefore, option B is the correct answer.

What process involves the change of an allele's frequency in a
population due to the fitness benefit it gives to the individuals
who have it?
Answer:
The correct answer is - natural selection.
Explanation:
The change of an allele's frequency or microevolution in a particular population due to its fitness benefit it provides to the individuals of the population can be caused by the natural selection process. Relative reproductive success is a measure of Fitness.
The change of an allele's frequency in deleterious traits mostly decreases in a population and this process is known as adaptive evolution. There is no or very small number of relative reproductive success present.

A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.
