Write a paragraph 4-5 sentences as to which one you think is better sexual or asexual reproduction
Answer:
Asexual
Explanation:
I think Asexual reproduction is better because you only need one reproduction Creature. For example plants, they are asexual so they do not need to worry about mating. Instead they can just create more plants by doing nothing. This helps us because we get more plants in a shorter amount of time. another example of Asexual reproduction is cross-pollination which is also an amazing way of creating more plants in a shorter time.

Explanation:
You are given a protein with the following amino acid sequence:
methionine (nonpolar)-glycine (nonpolar)-serine (polar)-alanine (nonpolar)-lysine (polar)
If an amino acid substitution occurred in this polypeptide chain, predict which option would have the most
significant impact on the structure and function of the protein.
a. Serine is replaced by lysine (polar)
b. Glycine is replaced by alanine (nonpolar)
c. Alanine is replaced by leucine (nonpolar)
d. Lysine is replaced by tryptophan (nonpolar)
?
Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
A cold front often brings intense weather changes such as thunderstorms while a warm front often brings light rain or drizzle. Why is this the case?
Answer:
The front term is associated with an area where two air masses met and as it is usually the condition with heavy rain, fierce wind, snow and other violent weather like a war situation. The front could be warm, cold, occluded or stationary depends on the type of weather.
The cold front is associated with lots of thunderstorms and other intense weather while the warm front changes with drizzly rain and warmer weather due to the fact that in a cold front, replacement of warm air by the cold air is faster while in a warm front, the replacement of cold air by warm air is gradual
Atoms of A decay to atoms of B with a half-life of 200,000 years. If there are 20,000 atoms of A to begin with, how long will it take for there to be 2,500 atoms of A?
Answer:
The correct answer is: 600,000 years
Explanation:
Half-life is the time which is essential or required to decrease a specific substance to half of its initial amount of the substance. So, if a substance has a half-life of 200,000 years then it means it takes 200,000 years to decrease or change into a new substance and remain half of its initial quantity.
half-life amount
0 20000
1 10000
2 5000
3 2500
total half-life = 3 to 2500 atoms of A
so, the time will be = 3 * 200,000 years
= 6000000
Put the steps in the proper order to explain the flow of information from the DNA sequence to a functional protein.
1. The codon sequence in mRNA determines the amino acid sequence in a polypeptide.
2. Each codon in mRNA codes for a specific amino acid.
3. The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.
4. The final structure of a protein determines its function.
5. Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA.
Answer:
5. Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA.
2. Each codon in mRNA codes for a specific amino acid.
1. The codon sequence in mRNA determines the amino acid sequence in a polypeptide.
3. The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.
4. The final structure of a protein determines its function.
Explanation:
The process of gene expression follows the central dogma of biology I.e. Gene (DNA) --> mRNA ---> Protein. The process of gene forming mRNA is called transcription while the process of mRNA forming protein is called translation.
Based on this, the order of the flow of information from the DNA sequence to a functional protein is:
- Each three nucleotides in the gene template DNA codes for a three nucleotide codon in mRNA (transcription).
- Each codon in mRNA codes for a specific amino acid.
- The codon sequence in mRNA determines the amino acid sequence in a polypeptide (translation).
- The sequence of amino acids in a polypeptide determines how the protein will fold and possibly bind with other polypeptides to form a mature protein.
- The final structure of a proteiin determines its function.
The order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function'.
During gene transcription, a fragment of DNA referred to as 'gene' is used as a template to create an mRNA, which is then used to synthesize a polypeptide.
The triplets of nucleotides or 'codons' in the mRNA sequence determine the amino acid sequence in the nascent polypeptide chain.
The synthesized protein is then folded in the endoplasmic reticulum (ER) and thus adopts its three-dimensional (3D) conformation.
Protein folding is achieved by specific proteins called chaperones that help to correctly fold the protein, which adopts a mature conformational active state.
In conclusion, the order is 'three nucleotides in DNA codes for a codon', 'each codon codes an amino acid', 'codon sequence determine amino acid sequence', 'amino acids determine protein folding' and 'final protein structure determines its function' (order 52134).

Look at the graph. Explain how the two population are related to each other
both species had growth in number within the same time period
What term is used to describe the number of individuals moving into a population?
Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a tree. Sunlight shines only three months out of the year. A stream supplies an abundance of water in a forest.
Answer:
Sunlight shines only three months out of the year.
Explanation:
I think this is right
Because abundance means a large amount so there would be no competition there.
If organisms share a place to sleep then that means no competition
If a living thing is consuming berries on a tree then the living thing is just eating
But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.
The statement that describes competition in an environment is option B a living thing consumes berries on a tree. Thus, consuming berries on a tree is reducing the availability of the food for other livings depends on the berries.
What is survival of living things?In the nature, the concept that survival of the fittest domintates. The organisms which are fit physically and are smart to gather food will survive in the nature otherwise they will extincts.
An ecological community is a collection of populations of at least two distinct species that interact both directly and indirectly in a specific geographic area. Within this community, diffrent organisms can be found .
Numerous ecological characteristics and functions, including nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can have a variety of different natures.
Because of this, ecological interactions between particular individuals and entire species are frequently difficult to identify and quantify and depend on their scale and context they face extinction. Hence, option B is correct.

Which division has a single preganglionic neurons with many axon collaterals that forms 20 or more synapses with postganglionic neurons?
a. sympathetic motor division
b. parasympathetic motor division
c. sympathetic sensory division
d. parasympathetic sensory division
Answer:
i believe its c

How do healthy cell decide when to divide?
Answer:
Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
A healthy cell decides when to divide by sensing and receiving signals from its surrounding environment.
The cell cycle can be divided into interphase and a mitotic (M) phase.During the interphase, the cell synthesizes all materials required (i.e., proteins, DNA, etc) to divide during the M phase.During the cell cycle, a cell modulates its division by communicating with other cells via specific chemical messenger molecules known as cyclins. Cyclins are proteins that interact with Cyclin-dependent kinases (CDKs) and thus function as molecular switches that regulate the progression through the cell cycle.In conclusion, a healthy cell decides when to divide by sensing and receiving signals from its surrounding environment.
