What are the symptoms of Ruşts?
Answer:
Pale leaf spots eventually develop into spore-producing structures called pustules.
The pustules are found most commonly on the lower leaf surface and produce huge numbers of microscopic spores.
Pustules can be orange, yellow, brown, black or white.
In some cases there may be dozens of pustules on a single leaf.
Explanation:
Compare primary succession and climax community. Be sure to identify how long-term survival of species is dependent on resources that may be limited.
Answer:
Primary succession is the colonization of species of organisms on life-less barren lands after a volcanic eruption, newly formed land, or sand dunes. Lichens and mosses are the known primary succession community of organisms that helps in developing conditions for secondary succession by breaking rocks and providing soil.
After a fair amount of time, there are new species of organisms that grow and colonize in the land and these are, and ultimately the community becomes fairly stable. A climax community is a more stable, mature community that undergoes little or no change which can live for hundreds of years on the land.
The long-term survival of species is dependent on various kind of resources that may be limited, this can be explained by the lichens and mosses that have enough amount of nutrition and resources during primary succession but as new organism comes with complex structure and competes with these lichens and mosses their number decline due to limited amount of resources.
5. Explain the process through which natural selection can lead to a new species of organism.
Answer:
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to specistion, where one species gives rise to a new and distincly different species.

Number the steps from when a stimulus is received to when the body reacts.
_____ The stimulus is received by sensory receptors.
_____ Motor neurons cause muscles to contract so the body can react to the stimulus.
_____ The brain processes the information through interneurons.
_____ Interneurons transfer response information to motor neurons.
_____ Sensory neurons carry stimulus information to the brain or spinal cord.
Answer:
The correct answer is -
1 - The stimulus is received by sensory receptors.
2 - Sensory neurons carry stimulus information to the brain or spinal cord.
3 - The brain processes the information through interneurons.
4 - Interneurons transfer response information to motor neurons.
5 - Motor neurons cause muscles to contract so the body can react to the stimulus.
Explanation:
In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.
These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.

Explanation:
Identify structure B in Figure 12-5:
A) aRNA
B) mRNA
C) rRNA
D) tRNA
I need help please
Answer:
B
Explanation:
mRNA is the messenger RNA that exits the nucleus and moves over to the ribosome, but it doesn't go in, tRNA goes in, figure G is tRNA.
Structure B given in the diagram is mRNA which is released out of the nucleus to undergo translation for the synthesis of proteins. So option B is correct.
What is the role of mRNA in protein synthesis?The mRNA carries the genetic information of an individual from the nucleus of the cell to the cytoplasm. The information encoded in the DNA is first transcribed into mRNA and the mRNA is then transported into the cytoplasm for translation.
The process of translation is aided by the protein factories of the cell which are the ribosomes. The ribosomes bind onto the mRNA and start the process of synthesis with the help of the initiator tRNA and further elongate the chain of amino acids to synthesize a complete polypeptide. There are two different types of ribosomes present in the prokaryotic and eukaryotic cells to carry out translation.

Answer:
Please find the mRNA and amino acid of the DNA sequence in the table below.
Explanation:
This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.
The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;
DNA = mRNA
- ATG = UAC
- GTA = CAU
- CAA = GUU
- AAT = UUA
- GCG = CGC
- TGT = ACA
- ACT = UGA
- CCC = GGG
- TAG = AUC
Using the codon chart attached as an image, the translation of these mRNA codons is as follows:
mRNA = amino acid
- UAC = tyrosine (tyr)
- CAU = histidine (his)
- GUU = Valine (Val)
- UUA = Leucine (leu)
- CGC = Arginine (Arg)
- ACA = threonine (Thr)
- UGA = STOP codon
- GGG = Valine (Val)
- AUC = Isoleucine (Iso)

¿Qué tipo de proceso metabólico se realiza cuando los lípidos y los fosfolípidos y triglicéridos se forman a ser moléculas sencillas dentro de la célula?
Answer:
catabólico
Explanation:
Los procesos metabólicos pueden ser:
Anabólicos: donde se forman moléculas más complejas a partir de moléculas simples. Esta formación de moléculas o estructuras más complejas consume energía. Catabólicos: donde se degradan o descomponen moléculas grandes o más complejas en otras más simples. Este proceso libera energía, que es utilizada en otros procesos y reacciones.En base a esto, la formación de moléculas sencillas a partir de moléculas grandes como los lípidos, fosfolípidos y triglicéridos es es proceso catabólico. En esta descomposición se produce energía para ser usada en otras reacciones.

Lodgepole pine trees produce seeds in cones. The cones open after being exposed to high temperatures created by wildfires. How does this adaptation help the lodgepole pine survive?
A) It allows the lodgepole pine tree to make more seeds in cones that are hard to open.
B) It creates more wildfires for the lodgepole pine tree to reproduce.
C) It makes the seeds travel and grow in areas where there are no wildfires.
D) It helps the lodgepole pine tree to protect the seeds and to reproduce.
Answer:
D
Explanation:
A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.
Answer:
D
Explanation:
A It allows the lodgepole pine tree to make more seeds in cones that are hard to open. IS WRONG B) It creates more wildfires for the lodgepole pine tree to reproduce. IS WRONG C) It makes the seeds travel and grow in areas where there are no wildfires. DEFINITLY NOT so that leaves it with D It helps the lodgepole pine tree to protect the seeds and to reproduce.
In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine
Answer:
23%
Explanation:
According to Chargaff's law A = T and G = C
T = 27%
A = 27%
27 + 27 = 54
100 - 54 = 46
46/2= 23
So 23%
