How can plant crops be modified so that they do not need to be sprayed with pesticides that are also harmful to humans like normal crops are?A. They can be given human DNA so that the pests will not want to eat them.
B. They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
C. They can be given DNA to allow them to resist harsh conditions.
D. They cannot be modified to be better than organic crops.

Answers

The correct option for the modification done that needs to be sprayed with pesticides is option (b) They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.

Here, we deal with the concept of genetically engineered crops, also called "genetically modified organisms" i.e., GMOs. GMOs approach the specific genes from bacteria of other organisms that produce the required toxins that are harmful only to pests that are inserted into the DNA of crops.

GMOs are examined by crops like Bt cotton or Bt corn. They are genetically modified genes from the bacterium Bacillus thuringiensis (Bt), which are produced by the toxic proteins of certain insects. The use of genetically modified organisms is a complex issue related to the potential health effects, environmental impact, regulatory oversight, and many more.

Which kind of relationship would a dog and a tick have?a. competitive relationship
b. commensality relationship
c. mutuality relationship
d. parasitic relationship

Answers

Answer: parasitic relationship

Explanation:

This type of relationship involves the parasite and the host.the parasite is the organism which lives in or on another organisms,called the host.

The parasite obtains food and shelter from the host and causes harm to the host.The host does not benefit rather it is harmed.

In this example,the dog is the host and the tick is the parasite.the tick has mouthparts modified for feeding from the host. It lives on the body of the dog , therefore it is an ectoparasite. The tick may cause disease and discomfort to the dog.

Plants can also be parasites;for example there are plants which lives on their host and gets nutrition from it while causing disease to it

The correct answer is D.

Why do cells undergoing mitosis require one set of divisions, whereas those undergoing meiosis require two sets of divisions? what is the end result of meiosis?

Answers

Mitosis, you see, is somatic (body) cell division, and the DNA in the nucleus during Interphase can replicate by doubling the chromosomes before the actual mitosis or cell division process of splitting into TWO identical cells (and they function the same with the same number of identocal chromosomes too! So they are called Diploid cells with 46 chromosomes!)

Meiosis is sperm/egg division and must divide twice to produce FOUR sperm or egg cells. Sperm goes through I- PMAT just like mitosis, but goes through PMAT again after that! They create four Haploid gametes (sex cells) with 23 chromosomes so that when an egg and a sperm unite in sexual reproduction, the zygote (fertilized egg) will have exactly 46 chromosomes like the normal number of chromosomes in a somatic cell. ^^

What would most likely happen to the carbon cycle if there were no more plants on Earth?Animals would consume more carbon.
More carbon would be released from fossil fuels.
Carbon would build up in the atmosphere.
Animals would perform more photosynthesis.

Answers

Plants use carbon to live, just like humans use oxygen. It's a virtuous cycle sine humans breathe oxygen and expel carbon, and plants "breathe" carbon and expel oxygen.

If plants weren't there to "breathe" the carbon, it would just sit in the world, and build up in the atmosphere.

the answer would be ( c ) Carbon would build up in the atmosphere.

Determine the most stable secondary structure that can be formed from the RNA oligonucleotide 5’-GAGUGCGCGAGCCUCU-3’. Consider only Watson-Crick base-pairing

Answers

Complementarity is achieved through interactions between nucleobases. In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). RNA secondary structure is achieved when two regions of one strand base pair and form a double helix.
Respecting the rule of complementarity and base-pairing, some of the bases will pair and some will not, as it can be seen on the image. The stability depends on helix length, base composition, and the number of mismatches.
