How did the probabilites of yellow seeds and green seeds compare with each other?
Answers
If we assume that the question is referring to the probabilities of yellow and green seeds in a genetic cross between two heterozygous pea plants, the probabilities would be equal (1:1) according to Mendelian genetics. This means that there is an equal chance of a seed being yellow or green.
However, if the question is referring to probabilities in a different context, such as the proportion of yellow and green seeds in a bag of mixed seeds, or the probability of a yellow seed developing into a plant versus a green seed, the probabilities would be different and would depend on the specific situation.

In 4 or more complete sentences, describe the process of protein synthesis and explain how transcription and translation creates protein
Answers
Protein synthesis occurs in the cell and is divided into 2 stages, namely transcription and translation. The process of transcription occurs in the cell nucleus by copying the genetic code in DNA and forming mRNA strands which are duplicates of DNA.
The RNA strands that are formed will come out of the cell nucleus and then undergo a translation process that occurs in the cytoplasm. With the help of ribosomes, the amino acids will line up according to the sequence of the genetic code in the mRNA to form polypeptide chains that make up the protein structure.
What is protein synthesis?
Protein synthesis is the formation of proteins in the human body and occurs in the smallest units, namely cells. Protein synthesis is divided into 2 stages, in the following order:
1. Transcription
Transcription is the process of copying the genetic code or DNA that occurs in the cell nucleus or nucleus. The process of copying the genetic code is carried out by unbinding the DNA with the help of RNA polymerase, then forming a copy of the genetic code that is complementary to the sequence of hydrogen bases in the DNA. The process of transcription produces a strand of genetic code called mRNA or RNAd.2. Translation
Translation is the process of translating the genetic code contained in the mRNA and occurs in the cytoplasm. With the help of the ribosome, the mRNA will be translated and the amino acids will move towards the ribosome. Amino acids will form a sequence that is complementary to the mRNA so that a polypeptide strand that makes up the protein molecule is formed.Learn more about Protein synthesis at https://brainly.com/question/15404950
#SPJ1
1. Transcription:
Transcription is the first step in protein synthesis and takes place in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. It involves the conversion of genetic information from DNA into a complementary RNA molecule. Here's how it works:
a. DNA unwinding: An enzyme called RNA polymerase binds to a specific region of the DNA molecule known as the promoter. The DNA molecule unwinds at this site.
b. Complementary RNA synthesis: RNA polymerase reads the DNA template strand and synthesizes a complementary RNA molecule, using adenine (A), cytosine (C), guanine (G), and uracil (U) as the RNA bases, instead of thymine (T). This newly formed RNA molecule is called messenger RNA (mRNA).
2. Translation:
Translation is the second step in protein synthesis and occurs in the cytoplasm, specifically at the ribosomes. It involves the conversion of the mRNA molecule into a functional protein. Here's how it works:
a. Initiation: The ribosome attaches to the mRNA molecule at a specific start codon (usually AUG), signaling the beginning of translation.
b. Elongation: Transfer RNA (tRNA) molecules bring amino acids to the ribosome, guided by the mRNA codons. These tRNA molecules have anticodons that complement the mRNA codons.
c. Peptide bond formation: As the ribosome moves along the mRNA molecule, it catalyzes the formation of peptide bonds between the amino acids carried by tRNA molecules. This forms a growing polypeptide chain.
d. Termination: Translation continues until a stop codon (UAA, UAG, or UGA) is encountered on the mRNA. At this point, a release factor binds to the ribosome, leading to the release of the completed polypeptide chain.
In summary, protein synthesis begins with transcription, where DNA is transcribed into mRNA. Then, during translation, the mRNA is decoded by ribosomes, and amino acids are linked together to form a polypeptide chain, which eventually folds into a functional protein. This intricate process ensures that the genetic information encoded in DNA is faithfully converted into the proteins that carry out essential functions within cells and organisms.

C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answers
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

What is an ecosystem and what are its parts and functions?
What can challenge an ecosystem?
What are the roles of the water and food cycles in an ecosystem?
Answers
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.

C. Male and female tigers cannot grow as large as ligers.
D. Female ligers can produce offspring with male lions or tigers.

A.
Explanation:
Because it makes sense that you NEED a Male Lion and a Female Tiger to produce a Liger. That's the only possible way and I'm 100% sure this answer is correct :)
Male lions and female tigers can produce offspring. Thus the correct option is A.
What is liger?The offspring of a lion and a tigress is called a liger.
Although they rarely meet in the wild, lions and tigers are still so closely related that they are able to interbreed, and in captivity they occasionally do. But successful interbreeding is the key, and the hybrid offspring are usually sterile and short-lived.
