Weight is a quantitative trait and mice with defective leptin tend to have problems controlling weight since this gene is associated with it.

<h3>What is a quantitative trait?</h3>

A quantitative trait is a phenotypic feature controlled by many genes and the interaction with the environmental factors.

Weight, height, behavioral features are all examples of quantitative traits because these types of phenotypic features show continuous variation.

Quantitative traits are modulated by gene interactions and therefore exhibit both epistatic and pleiotropic effects.

The leptin gene is a gene in mammal involved in neuronal control to metabolic signals and thereby it is associated with weight.

In conclusion, weight is a quantitative trait and mice with a defective form of the leptin gene tend to have problems controlling weight because it is associated with this trait.

wlad13 [49]

Answer:

Peppermint oil and morning, peppermint oil and night, lavender oil and morning, lavender oil and night

Step-by-step explanation:

Fertilisers are substances, which could be organic or inorganic, that is added to soil to increase crop yield.

Pesticide can be defined as substances that are used to control pests in an environment. Example of a pesticide includes:

- fungicides,

- herbicides( these are used to kill unwanted plants) and

- insecticides.

From the existing knowledge that the time of day the fertilizer is applied, morning and night affects the pesticide, and the Company managers know that peppermint oil or lavender oil will be used.

The insects should be subjected to the following treatments to effectively compare all combinations of these choices listed above:

- Peppermint oil and morning,

- peppermint oil and night,

- lavender oil and morning,

- lavender oil and night

Question 8 of 10
Fynjy0 [20]
I believe it’s A but I’m not too sure


Reason; Warm air rises, and when it rises it becomes cooler. ... If the pressure of the surrounding air is reduced, then the rising air parcel will expand. The molecules of air are doing work as they expand. This will affect the parcel's temperature (which is the average kinetic energy of the molecules in the air parcel).

How are scientists able to use fossils of extinct organisms as evidence?
nikdorinn [45]

The answer is; C

Fossil fuels are the remains of an organism  that lived in the past and have been preserved  or their impression has been preserved. Fossils are studied to identify the difference (genetic and phenotypic) between past and future related organism  and are carbon dated to determine the time in which the organisms existed. The study of fossils is called paleontology.

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
