The article Bananas Under Attack claims that scientists need to research how banana genes might be manipulated by humans so that

they can resist infection by the Black Sigatoka fungus.
Construct an argument that supports the scientists’ claim about how to combat the Black Sigatoka in banana crops. In your response be sure to include:

-An explanation of how knowledge of cause-and-effect relationships in how traits occur in organisms has led to advances in technology.
-Scientific reasoning related to why humans influence the inheritance of traits.
-Appropriate evidence from the resources provided.

Answer:

Explanation:

Gert Kema, a professor of tropical plant pathology at Wageningen University and a banana expert, led the study. "Black sigatoka has significant social, environmental and economic implications around the world. Thanks to the DNA sequencing of Pseudocercospora, we gain deeper insight into the interaction between the fungus and  banana plants. It can provide us with clues to increase the sustainability of banana cultivation and make it better for the environment, the locals, and the economy. For example, the findings show production and It provides us with the opportunity to develop  banana plants that are suitable for export and  resistant to black sigatoka. ”

This new understanding of the DNA of  black sigatoka also provides new information for more effective development. increase. And hopefully a crop protection product that is less harmful to the environment. This can reduce the amount of spray and improve the quality of life for those who work in  plantations and those who live nearby.

Choose the CORRECT statement concerning the cell membrane lipid molecules
VashaNatasha [74]

Answer:

The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)

Explanation:

Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.  

Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur
mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

w=mg     ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

g=\frac{GM}{r^2}

where, g = acceleration due to gravity = ?m/s^2

G = Universal gravitational constant = 6.67\times 10^{-11}Nm^2/kg^2

M = mass of the planet = 5.97\times 10^{24}kg

r = distance of the person from the planet = 6.38\times 10^6m

Putting values in above equation, we get:

g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2

Putting this value in equation 1, we get:

w=65kg\times 9.782m/s^2=635.83N

Hence, the weight of the person above the surface of a planet is 635.83N.
