Answer:
Nematode.
Explanation:
Heartworms belongs to phylum Nematoda, their biological name is Dirofilaria immitis. Their body structure is a tiny thread-like parasite roundworm. Adult heartworms always live in the lung arteries and the heart of the dogs and other mammals, it can spread from one species to another by the mosquito bites. Some characteristics of Nematoda phylum are:
1) Their body structure is triploblastic, bilaterally equal and cylindrical in shape.
2) They show a tissue-level organization.
3) Their body keeps a pouch or pseudocoelom.
Answer:
A healthy radish plant growing in a greenhouse is covered with a screen box that blocks sunlight. After 10 days, the mass of the plants has <u>decreased</u> because the rate of cellular respiration is <u>higher than</u> the rate of photosynthesis.
Explanation:
If a healthy plant would be covered with a screen box for a period of 10 days, the rate of photosynthesis would be decreased significantly. We know that a plant essentialy needs sunlight to perform photosynthesis. Further, when the photosynthesis is already stopped, the <u>cellular respiration would continue and the plant would loss most of its water content</u>. Ultimately, after a few days, the plant biomass would start decreasing as well. The period of 10 days is sufficient enough to see the loss of plant biomass and decrease in photosynthesis rate. Normally, results are evident after 24 hours.
Answer:
The terms are not included in the question but their terms are:
Gene- a segment that contains the information for making proteins
DNA- A complex molecule containing the genetic code
Explanation:
All living organisms contains genetic material (containing genes) in their cells. A gene is a segment of DNA that encodes the information needed for the synthesis of certain functional products called PROTEIN. The genes undergo expression i.e. transcription into RNA and translation into protein. This protein is responsible for the phenotype living organisms exhibit.
The genetic material in most organisms is the DNA, which is a complex molecule and one of the two types of nucleic acids containing long polynucleotide chains. The DNA stores the genetic information needed for the expression of genes i.e. genetic code. The information are stored in the four nucleotide bases (Adenine, Guanine, Cytosine and Thymine) that constitutes the DNA.
Stem cell research can help us understand how disease occur, as well as help scientists find out what drugs can be effective to fight diseases.
Some drawbacks include adults don't have many stem cells and actually in fact, stem cell research costs a lot of money (well in the U.S. it does..)
