Answer:
External Respiration.
Explanation:
External Respiration is the type of respiration in which exchanges of gases occurs between the lungs and the bloodstream i.e. pulmonary capillaries. Inside the lungs, oxygen is loaded into the hemoglobin and carbon dioxide waste is unloaded, this process is called external respiration. This respiratory process takes place through the help of hundreds of millions of microscopic alveoli.
Which of the following is NOT of the major biogeochemical cycles?
A.Life cycle
B.Water cycle
C.Carbon cycle
D.Phosphorus cycle
water cycle............
The following is NOT of the major biogeochemical cycles D.Phosphorus cycle is D.Phosphorus cycle.
What is the difference between Carbon cycle and Phosphorus cycle?The major distinction among carbon and phosphorus cycle is that carbon cycle interacts with the environment while phosphorus cycle does now no longer engage with the environment. Therefore, the carbon cycle is a sort of gaseous biking while the phosphorus biking is a sort of sedimentary rocks.
As in comparison to nitrates & different macro elements, decomposers take longer time to decompose any lifeless biota into phosphates. Decomposers are organisms mainly a soil bacterium, fungus, or invertebrate, that decompose natural material. These are the motives for phosphorus cycle being the slowest biogeochemical cycle.

What would be the resulting polypeptide chain that is produced from the DNA template code: TACTTCAAAATC? Use the following RNA codon to amino acid table to help you figure out the resulting polypeptide. Show your steps.
Answer:
Methionine- Lysine- leucine- stop
Explanation:
This question is describing the processes of transcription and translation, which are both involved in protein synthesis. Transcription is the synthesis of a mRNA molecule from a DNA template while translation is the synthesis of a polypeptide/amino acid sequence from a mRNA template.
The following DNA molecule was given as follows; TAC TTC AAA ATC. Firstly transcription will synthesize an mRNA molecule based on complementary base pairing rule. The resulting mRNA will be: AUG AAG UUU UAG
Next, the process of translation which involves the synthesis of an amino acid sequence from mRNA. Using the genetic code will produce the following:
Methionine- Lysine- leucine- stop

A boy picks up an earthworm and place it on a white tile. He observed that the earthworm has difficulty in moving forward.
Explain why.
Answer:
A number of tiny hair like bristlez are present on the lower surface pf an earthworm's body. These bristles help it to get a good grip on the surface of q ground.However these bristles donot provide good grip on plain glass tiles.
Earthworms have microscopic hairs or bristles all over their body which provide the necessary traction while movement. These bristles or setae are present on each segment of their body and it imparts the necessary grip or anchorage for forward and backward movement.
Tile is smooth in nature so earthworms cannot move as the setae will not get sufficient surface support to move the body.

In paragraph form (automatic 1-pt deduction if not), explain the evolutionary benefits of sexual reproduction as a means of increasing variation. Be sure to include (a) at least two ways in which sexual reproduction impacts genotype (i.e. genetic effects), and (b) two ways in which sexual reproduction may affect phenotype (i.e. trait effects).
Answer:
See explanation
Explanation:
According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.
During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.
This variation may also lead to the observation of new phenotypes in the population.
