Answer:
C. By causing auxin to migrate in to the shaded portion
Explanation:
Auxin is the most important plant hormone involved in the apical growth of plant parts. Auxin is evenly distributed in a plant with a normal light condition, however, when a particular part of a plant is exposed to sunlight, that illuminated part contains less auxin. The hormone is transported to the shady part of the plant via diffusion.
This causes more auxin to be present in the shady part than the illuminated part, hence, the shady part experiences a faster and elongated growth. This elongated growth in the shaded portion of the plant causes it to grow towards the direction of the light, a process called PHOTOTROPISM.
Trees with light brown bark dominate an ecosystem. The ecosystem has populations of insects that thrive on the tree bark. Over time, some insect species developed certain physical characteristics that helped them thrive on the tree bark. These physical characteristics also helped the insects defend themselves from predators. Which insect species is probably the species with the new physical characteristics?
I'm assuming this is referring to the Peppered Moth, a species of moth that adapted to the change of color on tree bark. The tree bark changed color as a result of local pollution. The moths (over the course of generations) changed color as well that better suited camouflage upon the new color of the tree bark.

Which is part of the nonspecific immune response?
O A. Fever
O B. B cells
O C. Lymphocytes
O D. Making antibodies
Answer:
A. Fever
Explanation:
Fever is part of the nonspecific immune response. Therefore option A is correct.
Fever serves as a defense mechanism against infections. When the body raises its temperature, it creates an environment that is less favorable for the growth and reproduction of many pathogens.
Higher temperatures can also enhance the activity of immune cells, such as white blood cells, allowing them to function more efficiently in fighting off the infection.
Fever is triggered by the release of certain chemicals, such as cytokines, by immune cells in response to the presence of pathogens.
These chemicals act on the hypothalamus in the brain, which regulates body temperature, causing it to increase.
Thus, fever is a physiological response of the body to infection or inflammation and is considered a part of the nonspecific immune response.

Earlobes can be either attached or detached. The allele for attached earlobes
is recessive (e), and the allele for detached earlobes is dominant (E). What
must be true if a boy is born with attached earlobes?
A. He has a heterozygous genotype.
O B. He has no E alleles.
C. He has no recessive alleles.
O D. He has one of each allele,
SUBMIT
Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
If a boy is born with connected earlobes, he has no E alleles because the allele for detached earlobes is dominant (E), whereas the allele for attached earlobes is recessive (e). So, the correct option is B.
What is Dominant allele?A dominant allele is one that will overpower a recessive allele's expression. Hence, only the trait linked to the dominant allele is manifested when a dominant allele and recessive allele coexist in the genotype of offspring. Consequently, for a recessive allele phenotype to manifest, both of the recessive allele must be present in the progeny.
A recessive allele causes connected earlobes (e) while the dominant earlobe detachment allele (E)
A child with the EE genotype would have disconnected earlobes.
As features of dominant alleles are manifested in heterozygous genotypes, offspring with the Ee genotype would also have disconnected earlobes. Only the child with the ee genotype would have connected earlobes. A homozygous recessive genotype is genotype ee.
Thus, the correct option is B.

B) Arrow Q shows the water vapour escaping from the leaf. What is the name of this process? C) How are cells of type G adapted to their function?
Answer
:Photosynthesis can be explained in four simple steps, as follows.
Step 1:
The plant gathers sunlight from the chlorophyll in the cells to convert into energy.
Step 2:
The light energy then reactions and forms hydrogen and oxygen.
Step 3:
The hydrogen joins with carbon dioxide and create sugars.
Step 4:
The sugar is then separated, some to be used as the structure in the cell wall, and some stored in the ATP for later use.

Answer: The casual relation is a cause and effect relation whereas the correlation is when the two variables are related based on two or more parameters.
Explanation:
A casual relationship can occur in between the two events, the first occurs before the other. The first one is cause and the other one is effect. A correlation can be defined as the relation between the two variables. It does not imply causation. It can be defined as the causal relation between the two variable that are correlated.
Answer:
The difference between causal and correlational relationships is as following:
A correlational relationship is defined as a measure of relationship between two variables and the variables can be negatively correlated, positively corelated or not correlated at all.
Relation between two events said to be causal relation, if the occurrence of the first causes the other. It means the effect of second event should be caused by the the first event.
So, causal relationship between two variables must be correlated.
For example: there is a positive correlation between the organisational behaviour and work done. if any one employee will deny to work from the group of 4 employees it will affect other employees behaviour and reduces their working ability, which will reduce tehir work done. It means that organisational behaviour between employees is the cause of less work done. so, the second event (work done) is the cause of first event (organisational behaviour) and they both are positively correlated as well.

Solution types of weathering requires the presence of water. Thus option D is correct.
What is the process of weathering?The process in which break down or disintegration of rock surface occurs due to natural occurring process like rains, snow, wind, or sunshine, is called as weathering.
The origin of weathering may be due to continuous biological, chemical, and physical processes on rocks, wood, soils surface or it may due to soil erosion which occurs with the movement of rocks, minerals, snow, wind etc.
Other physical factors include pressure where as one of the chemical factor include carbonation occur between water and carbon resulted in dissolving rocks area.
When rain water combines with carbon dioxide form carbonic acid, which is then reacts with calcium carbonate of rocks and minerals leads to rock weathering.
As the process of carbonation occur in presence of water, Hence Thus option D is correct.

DNA is translated into RNA and RNA is transcribed into proteins
RNA is transcribed into DNA and DNA is translated into proteins
DNA is transcribed into RNA and RNA is translated into proteins.
Answer:
DNA is transcribed into RNA and RNA is translated into proteins.
Explanation:
The central dogma of biology explains how gene is expressed in living organisms. Genes are segments of DNA that encodes or carry information for useful products called PROTEIN. However, these genes needs to be expressed. Gene expression occurs in two stages viz: transcription and translation.
Transcription is the first process of gene expression involving the synthesis of a RNA molecule from the gene-containing DNA molecule i.e. DNA is transcribed into RNA.
Translation is the second process of gene expression that involves the synthesis of an amino acid sequence from the information contained in the RNA transcript. These amino acid sequence forms the PROTEIN. Hence, RNA is translated into protein, which is responsible for certain phenotypes.
