New research shows how technology and experimental methods in science can always help and be of help when trying to find out the fine details and see how a theory should be updated and what is needed to be corrected in a certain hypothesis or theory. 


Dinosaurs they are termed as a diverse group of reptiles. They first appeared in the time of triassic.

After triassic and jurassic extinction event, dinosaurs became terrestrial vertebrates.

The results of genetic crosses derived from Punnet squares assume that each gamete contains one allele for each trait, which com
Gnom [1K]

Answer:

Independent assortment

Explanation:

The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.

So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.

This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.

Two-component regulatory systems rely on a balance of phosphorylation and dephosphorylation of sensor kinases and response regul
otez555 [7]

Answer:

The correct answer is the first statement.

Explanation:

A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.  

In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.

65. In dogs, wire hair (H) is dominant over straight hair (h). Two dogs produce offspring as shown in the Punnett square below.
valentina_108 [34]

About the question:

I failed to find the complete question with the Punnett square, so in the answer and explanation I will propose five options for crosses between dogs with different genotypes, and for each option, I will remark the percent of the offspring that is expected to have wirehair. You just need to look for the option that matches your Punnett Square.

Answer:

  • Option 1: HH  x HH ----> 100% of the progeny is wire-haired, HH
  • Option 2: HH x Hh---> 100% of the progeny is wire-haired, HH + Hh
  • Option 3: Hh  x  Hh --->75% of the progeny is wire-haired, 25% HH + 75% Hh
  • Option 4: Hh  x  hh ---> 50% of the progeny is wire-haired, Hh
  • Option 5: hh x hh ----> 0% of the progeny is wire-haired

Explanation:

You will find the complete explanation in the attached files due to technical problems

Greg and Andrea are trying to find out how long it takes amylase, a digestive enzyme found in saliva, to break down a sample of
enyata [817]
The answer is: the amount of the saliva samples must stay consistent while the amount of starch must vary.

The amount of the saliva samples must stay consistent because amylase, present in the saliva, is the independent variable which affects the dependent variable - the amount of starch. So, amylase will do its job while remaining surface area of the starch will depend on the starting amount of the starch.

What does the scientific method help test in environmental science?
slava [35]

Answer:

It helps to make scientific inquiries

Explanation:

Environmental science is a broad discipline which includes geology, physics, biology etc.

The nature of inquiries is often scientific. The procedures to follow in making useful deductions about environmental phenomenon must be guided scientifically.

Scientific methods is a systematic approach in which scientists can gather facts. Through their numerous observations, they formulate a sort of scientific guess called an hypothesis. Hypothesis can be tested over time and theory springs up. These theories can then be applied to tackle various related scientific puzzles.
