You're researching a steroid hormone that binds to a receptor inside the cell. Once the receptor binds to its hormone, the receptor moves into the nucleus of the cell. The result of hormone-receptor binding is that new mRNA molecules are made. The receptor is also a
Answer:
transcription factor
Explanation:
Transcription is the process by which a specific fragment of DNA (e.g., a gene sequence) is used as template to synthesize an RNA molecule, typically a messenger RNA (mRNA), which is then used to synthesize a protein by a process called translation. Transcription factors are proteins that bind to specific genomic sequences (e.g., promoter sequences) in order to alter the mechanism of transcription. Transcription factors function coordinately to stimulate or inhibit specific cellular processes (e.g., cell division, cell growth, cell migration, etc.) according to the cell type and stage of development. Transcription factors may act alone or form macromolecular complexes that stimulate or block the recruitment of the RNA polymerases (RNA pols), which are key enzymes required for transcribing a fragment of a DNA strand (e.g, a gene) into an RNA sequence during transcription.
What genotypes are observed when you cross a Dd parent
with another Dd parent?
a. 100% DD
b. 75% DD and 25% dd
c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd
Answer:
it is D. 25%DD ,50%Dd ,25%dd
If both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd. So, the correct option is D.
What do you mean by genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for our study.
Here, both the parents carry the genotype Dd, when Dd is crossed with Dd, the resulting offspring are 1DD, 2Dd, and 1dd.
Therefore, if both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd.

A simplified carbon cycle is depicted here. The release of carbon dioxide into the atmosphere can contribute to global warming. The statements describe the processes of forest fires, fossil fuel combustion, and plant respiration are they occur under anaerobic conditions primarily, they are all directly caused by human intervention, and they are primarily the result of microbial activity. Thus, option A, B, and C are correct.
What is carbon dating?Carbon dating or radiocarbon dating has been known as the method to identify the age of any substance by using the properties of radiocarbon. The method has been developed in late 1940 at university of Chicago.
Carbon dating has been the process by which we can find the extrapolated data which stored by tree rings can be identified which thousands year old.
Carbon has been known as the one of the chemical elements. Along with hydrogen, nitrogen, oxygen phosphorus and sulfur carbon has a building block of biochemical molecule ranging from fats, proteins and carbohydrates.
Therefore, A simplified carbon cycle is depicted here. The release of carbon dioxide into the atmosphere can contribute to global warming.

stay safe healthy and happy.Photosynthesis takes place in leaves. Leaves contain that allow for the exchange of gases during the process, and also help with the process of .
Answer:
The correct answer is - stomata, transpiration.
Explanation:
Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.
Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.

Which statement best describes the motion of the plates along these boundaries that causes the earthquakes? The plates push apart from each other with no subduction. Subduction occurs with the less-dense plate sinking below the other plate. Subduction occurs with the more-dense plate sinking below the other plate. The plates smash together with no subduction.
Answer:
D). The plates smash together with no subduction.
Explanation:
As per the question, the last statement most adequately demonstrates the movement of plates i.e. 'the plates hit together without any detraction' through concurring boundaries causing the earthquakes to take place. The continuous smashing of tectonic plates with one another leads to the development of a pressure towards both the rock layers by the time this stress is released through a shaky or convulsive movement of the Earth. Thus, option D is the correct answer.
