Explanation:
A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
What is a genetically altered hormone(GAH)?The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.
Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

When a new viral infection appears in a population,scientists usually try to develop a vaccine against the virus. Which substances would most likely be contained in the new vaccin
Answer:
Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine. Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine. Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine. Diluent: Used to dilute the vaccine in an appropriate concentration before being used. Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.How many valence electrons does phosphorus have?

that apply.
A)
The mRNA becomes a double stranded molecule.
B)
The mRNA brings an amino acid to the nucleus.
C)
The mRNA contains a start codon that reads AUG.
D)
The mRNA travels from the nucleus to the ribosome.
E)
The mRNA is exported from the cell through the membrane.
Answer:
C) The mRNA contains a start codon that reads AUG.
D) The mRNA travels from the nucleus to the ribosome.
Explanation:
mRNA is single stranded. The mRNA does leave the nucleus but does not leave the cell. The mRNA does not carry the amino acids, that job belongs to the tRNA and it brings them to the ribosome.
The formation of the mRNA from the DNA is called transcription. In this process, the mRNA has both the introns and the exons.
The correct option of the following question is D
The replication, transcription all process is occurs in the cytoplasm of the cell. After the process of replication, the DNA moves to the nucleus for the transcription process. The process of the formation of protein from the mRNA is called translation. The translation process occurs in the ribosomes.
The protein formation requires the ribosomes hence the RNA must be transferred to the ribosomes.
Hence, the correct option is D that is the mRNA travels from the nucleus to the ribosome.

What is complimentary DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.
These instructions are dispersed throughout 46 lengthy structures called chromosomes that are found inside each of your cells. Numerous smaller pieces of DNA, known as genes, make up these chromosomes.
Complementary sequence is a sequence of bases in a nucleic acid that can be combined to generate a double-stranded structure.
For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents for a different DNA nucleotide.
The DNA sequence can be:
DNA molecule 1: TACCGGATGCCAGATCAAATC, complimentary will be ATGGCCTACGGTCTAGTTTAG.DNA molecule 2: TACGGGGGCGTAACCACAACT, complimentary will be ATGCCCCCGCATTGGTGTTGA.DNA molecule 3: TACCTGTTAAGCTACAAAATT, complimentary will be ATGGACAATTCGATGTTTTAA.Thus, this is the complete match for the given scenario.

sunlight so that light energy can be converted to chemical energy? *
Large leaf size
Small seed size
Small Stem
Large root size
Answer:
The picture was NOT a part of that question. The correct answer is Large leaf size. A
Explanation:
Leafs trap sunlight to perform photosynthesis for chemical energy which takes place in the chloroplast.
Photosynthesis is the process by which plants convert light energy into chemical energy. Plants can trap more sunlight if the size of leaves is large. Thus, the correct option is A.
What is Photosynthesis?Photosynthesis is the process by which plants synthesize their food in the form of carbohydrates (sugars). This process takes place in the chloroplast of cell. It contains chlorophyll pigment. This pigment is responsible for trapping sunlight.
There are more chloroplast present on the leaf surface than other parts of cell. This organelle is responsible for the synthesis of carbohydrates in plants as they trap sunlight which is converted into chemical energy. The more the number of chloroplast in the cell, more will be the rate of photosynthesis in plants.
Therefore, the correct option is A.
