According to the simulation, _______ helps predators to survive by allowing them tosneak up on their prey.

Answers

The correct answer is Camouflage

The technique which is used by the animals to protect themselves from the predators. They prey usually changes the color of the body and match it to the surrounding environment so that the predators cannot recognize it.

Prey usually use this technique to protect themselves from the prey and helps in surviving.

Example: Chameleons, octopus et cetera.

According to the simulation, camouflage helps predators to survive by allowing them to sneak up on their prey.

in a given hybridization between two flowers, red "R" is dominant, and white "r" is recessive. In a cross between two white-flowered plants, all of the offspring had white flowers. If a plant grower wanted to produce red flowers, what should s/he consider during breeding?

Answers

Ans.

The dominant allele can be defined as the allele, which can express itself in both heterozygous and homozygous conditions. On the other hand, recessive allele can only express itself in homozygous condition (when both the alleles for recessive traits are present. It means presence of one dominant allele can hide the expression of recessive allele.

In given experimental flower, red color is dominant over white color of flower. So, 'if a plant grower wants to produce red flowers only, he should choose both the parent plants having red flowers as they have at least one allele for red color that would transfer to their offspring.'

Lets understand this in a calculative way,

Let the parents genotype be RR and Rr

The offspring’s produced are – RR, Rr, Rr, RR, Thus all the offsprings are white as r is recessive, for producing a red flower the offspring must have “rr” genotype.

Now if parents have Rr and rr genotype , then the offspring would have Rr, rr, rr, Rr giving two white and two red flower. Of the second case may be where both the parent white flower are the carrier with genotype “Rr”

Thus in order to produce red flower the parents with following genotypes is necessary –

a) Both parents having Rr

b) One parents with rr and the other parent with Rr genotype

What happens after genetically modified plasmids are inserted into bacteria?

Answers

The answer to the question is: Once a new DNA is inserted, the modified plasmid can be grown in bacteria for self-replication to make endless copies.
>The plasmid is genetically modified to produce 1 or 2 specific proteins from a pathogen and then purified for immunization.

>A plasmids are small double-stranded unit of DNA.They are usually circular but sometimes linear, that exists independent of the chromosome and is capable of self-replication. Each plasmid carries only a few genes.

Which best differentiates between chemical digestion and mechanical digestion? Chemical digestion happens in the small intestine; mechanical digestion happens in the mouth.

Chemical digestion involves the breaking down of food with enzymes;
mechanical digestion is breaking down food by chewing and tearing with teeth.

Chemical digestion is the breakdown of fats; mechanical digestion is the breakdown of proteins.

Chemical digestion is done only by the major structures of the digestive system; mechanical digestion is done by the accessory structures of the digestive system.

Answers

The answer is Chemical digestion involves the breaking down of food with enzymes; mechanical digestion is breaking down food by chewing and tearing with teeth.

Mechanical digestion means breaking down food mechanically. By chewing and tearing with teeth, food breaks down into smaller parts and no enzymes are used. Chemical digestion means breaking down food in a chemical manner. This is achieved by secreting enzymes, which break down chemical bond between food molecules.

The Best answer to the question stated above is "Chemical digestion involves the breaking down of food with enzymes;
mechanical digestion is breaking down food by chewing and tearing with teeth. "

Mechanical digestion prepares food for chemical digestion. It involves the chewing and mixing food with saliva, churning of food in the stomach, segmentation of intestines rhythmic local constrictions of intestine, causes mixing improves absorption. On the other hand chemical digestion breaks down complex food molecules into chemical building blocks, enzymes secreted into alimentary canal lumen.
