Scientists insert a gene from a firefly into the genome of certain bacterial species. When these bacteria are placed into tobacco plants and exposed to certain conditions, the plants will glow. Tobacco plants without the bacteria do not glow. Which conclusion is best supported by this experiment?
A. The firefly and bacteria share a common genetic code.
B. The bacteria transferred light-producing proteins to the plant.
C. The firefly and tobacco plant have a recent common ancestor.
D. Tobacco plants lack the ability to translate the genetic code of firefly gene.
The answer is A.
A GENE is being inserted into the tobacco plant, which permits it to glow.
The conclusion that should be best supported by this experiment is option A.
Supported by the experiment?At the time when the bacteria should be placed into the tobacco plants so here tobacco should be without the bacteria and this can't be glow. Also, the gene should be added into the tobacco plant moreover, the firefly and bacteria shared the common genetic code

what is the representative organism for sponges??
Worth 20 points!!!
Answer:
phylum Porifera
Explanation:
Sponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with choanocytes, cells with whip-like flagella.

CATCTATGAG to GTUGUTUCTC
No
Answer:
CTGACTGACC to GACUGACUGG
AGCTCCGATC to UCGAGGCUAG
GCTAATCGAT to CGAUUAGCUA
Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA

As we know that the leaves of plants are waterproof due to cuticle. On the same way, take some pieces of paper of leaf size and make them waterproof. after completion, put half of these paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof? Explain your observation and result with justifications
Answer:
its answer is:
No all the pieces of paper not remains waterproof. After making water into its pieces in the shape of leaves, it can't be able to defend water. As paper is non living thing and leave is part of living being so, paper is not waterproof but leaves is waterproof.

Answer:
Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring
Explanation:
Reproduction in dogs is a sexual process. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce diploid offspring.
The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. The random fusion of gametes further ensures that offspring from the same parents are different from one another.

What statement best describes symbiotic relationships?
O Different species live in close associations in an ecosystem.
Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.
The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.
For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.
In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.
Thus, the correct option is A. Different species live in close associations in an ecosystem.
