how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
When a star becomes a red giant it will
1.shrink
2.shrink and cool
3.shine hotter
4.expand and cool
Stars spend approximately from a few thousand up to 1 billion years as a red giant. The helium in the core eventually runs out and the fusion process stops. The star then shrinks until a new helium shell reaches its core.
Therefor the answer is 2.shrink and cool
I hope this helps!
Answer:
Shrink an cool I took the test
Chemical to thermal to electrical current?Energy conversion of corn
Answer:
A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.

How do rocks become igneous rock?
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes
Explanation:
So first when the sedimentary rock is formed and adds some heat pressure in which it turns to metamorphic rock, and after a long time heat + cool down which it will turn to igneous rock!
If the individuals in a population mate at random, and if allele h1 is at frequency 0. 60, what is the frequency of h1h1 offspring?.
Answer: Frequencies of two alleles in a gene pool before and after many random matings
Explanation:
Frequencies of two alleles in a gene pool before and after many random matings
The allele frequency of h1h1 in offspring is 0.36 if individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles.
What is the frequency of the allele?The number of times the allele of interest is detected in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to compute the allele frequency.
In a population, if individuals mate at random sampling if h1 has a frequency of 0.60, the frequency of h1h1 offspring is 0.36, in the population.
The frequency of alleles can be expressed as a decimal, a percentage, or a fraction. Allele frequencies vary from 0 (present in no people) to 1 (present in all individuals); in a population, all allele frequencies for a particular gene add up to 100%.
Therefore 0.36 is the frequency of h1h1 in the population for individuals at random mates for h1 frequency of 0.60 in the population.

Specialized structures are expressed with the help of mRNA. What role does mRNA play? (5B)
Assisting with replication by producing glucose
Creating bonds to form large polymers
Providing information from DNA that is used to form proteins
Making energy available for cellular activities
Answer:
The answer is C Providing information from DNA that is used to form proteins
Explanation:
i took the test
The statement that demonstrates the role that mRNA play in protein synthesis is as follows:
It provides information from DNA that is used to form proteins.Thus, the correct option for this question is C.
What is Protein synthesis?Protein synthesis may be defined as a type of biological process through which polypeptide chains are formed from coded combinations of single amino acids inside the cell. The process of protein synthesis terminates with the help of two processes:
Transcription.Translation.The process of transcription involves the copying of a DNA sequence of a gene in order to make an RNA molecule. This RNA molecule is known as mRNA which determines the linkage of DNA from the manufacturing of the proteins. This process is carried out in the nucleus of the cell.
While the process of translation involves the synthesis of proteins using the genetic information carried in messenger RNA (mRNA). This process is carried out in the cytoplasm of the cell.
Therefore, the correct option for this question is C.

The scenario could potentially result in new combinations of DNA in the offspring of the individual is a pair of homologous chromosomes fail to separate during anaphase I of meiosis. The correct option is d.
What is DNA?DNA is deoxyribose nucleic acid. The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins.
These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes. These chromosomes are composed of thousands of shorter DNA segments known as genes. During anaphase, I of meiosis, a pair of homologous chromosomes fails to split.
Therefore, the correct option is d, A pair of homologous chromosomes fails to separate during anaphase I of meiosis.

Answer:
Citric Acid Cycle
Explanation:
Fungi compose a very minor component of life in marine ecosystems yet are vital to the health of terrestrial ones. This is primarily due to their ability to:
Answer:
Break down lignin.
Explanation:
The continual slow degradation of the phenolic portions of lignin (humic acids) provides a long-term supply of nutrients to plants. Phytoplankton (the primary producers in aquatic systems) do not synthesize appreciable amounts of lignin, and so fungi are not necessary to decompose it!

D.
bull kelp, sweeps, water fleas, dinoflagellates
Crabs, pilchards, blennies and snappers are the examples of secondary consumers.
Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.
They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.
