White leaf disease is caused by phytoplasma. The disease infects the leaves and create white spots in them.
The farmers in Thailand are facing this issue with sugarcane crops. The organisms infect phloem tissues in sugar cane and cause the leaves to turn white.
The size and shape can change as sometimes there are fine white lines created while sometime there are white spots.
Scientists are trying to deal with such disease and an spray of liquid copper has been found beneficial to treat this disease. The white spot fungus stops to spread with the spray.

What theory explains why the Uranian system is on its side?
Answer:
Astronomers have always assumed that Uranus must have been knocked onto its side by a collision. Now a new idea suggests that the planet's remarkable tilt could have another explanation.

Answer:
Astronomers have always assumed that Uranus must have been knocked onto its side by a collision. Now a new idea suggests that the planet’s remarkable tilt could have another explanation.
by Emerging Technology from the arXivarchive page
December 3, 2009
One of the great mysteries of our Solar System is why Uranus is tilted on its side. Surely, if the solar system formed from the same rotating cloud of dust and gas, then all the bodies within it should rotate in the same way. And yet Uranus’ axis of rotation lies at 97 degrees to the plane of the solar system.

Define Siamese twins
Answer:
Conjoined twins are two babies who are born physically connected to each other. Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two fetuses will develop from this embryo, they will remain physically connected — most often at the chest, abdomen or pelvis.

Random distribution is also known as predictable spacing.
true ot false?
Random distribution is not the same predictable spacing. Hence, the correct answer would be False
In actual fact, random distribution can be said to be the direct opposite of predictable spacing.
For example, when a group of numbers is randomly distributed, each number has an equal chance of being located within the distribution. In predictable spacing, each number would have a predefined probability or an unequal chance of being located.

Please help I have one more attempt. I need help labeling the upper muscles of the arm.
There are four muscles in the upper arm. These muscles are Brachialis, Biceps brachii, triceps brachii, and coracobrachialis.
What is the function of muscles in the upper arm?The upper arm has many muscles which are arranged in different compartments. The muscles in the upper arm are the muscles that connect the scapula with the thorax and are responsible for most of the movement of the scapula. The muscles that link the humerus are responsible for the movement of the arm. The muscles in the arm or the forearm move the arm, wrist, and hand.
The humerus is where the muscles that move your arm are located. The humerus is made up of the following muscles: Tricep, Biceps, Brachial, and Bicepsioradial. The 20-plus muscles that cause the majority of wrist, hand, and finger movement are located along the arm. The labeled image of the arm is attached below.

13. A father and mother claim they have been given the wrong baby at the hospital. Both parents are
blood type A. The baby they have been given is blood type o. Does the genetic evidence support
their claim?
No, the claim is not based on scientific evidence because to heterozygous parents with genotype AO may have offspring with O phenotype and therefore OO genotype (proportion 1/4 of descendence).
What is the ABO blood type?The ABO blood type is a group of phenotypes controlled by a single locus, which is based on the alleles that encode surface antigens in red blood cells. The O phenotype is due to the recessive allele, while the A allele is dominant and therefore masks the O allele in heterozygous individuals.
Therefore, we can conclude that parents having the AO genotype may produce offspring with OO genotype

The bacteria Listeria monocytogenes is capable of doubling every 36 hours in the refrigerator at 4°C and can grow even when temperatures are less than 2°C. Therefore, L. monocytogenes is best classified as a psychrophile.
a. True
b. False
Answer:
True
Explanation:
Listeria monocytogenes is a psychrophilic food-borne pathogen that is problematic for the food industry. Structures of Csps from psychrophilic bacteria have not yet been studied.
Listeria is not killed by freezing. Growth is arrested altogether, but normal growth will be resumed after thawing.

The sodium-potassium pump does not do which of the following actions?
-Moves sodium molecules against their concentration gradient into the cell
using ATP.
-Moves sodium molecules against their concentration gradient out of the cell
using ATP.
-Maintains the cell's physiological needs by establishing an electrochemical
gradient.
-Moves potassium molecules against their concentration gradient into the cell
using ATP.
The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell with the use of ATP molecules.
In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.
https://brainly.com/question/24347696
Answer: Moves sodium molecules against their concentration gradient INTO the cell using ATP.
Explanation:
The sodium-potassium pump moves sodium molecules against their concentration gradient out of the cell and moves potassium molecules against their concentration gradient into the cell. It also helps to regulate internal physiological needs through gradients. However, it doesn’t move sodium ions into the cell—that occurs through passive transport.

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes
salt water freezes slower than fresh water

Select one:
a. They are examples on a structure called a microfilaments
b. They are all structures found in prokaryotic cells
c. They are microtubules
d. They are found in the nuclei of eukaryotic cells
Answer: c
Explanation: Spindle fiber: is a microtubules that comes out from the centrosomes when the cell is preparing for division. They are responsible for the segregation of sister chromatids and movement of chromosomes during mitotic and meiotic division.
Flagella: a slender threadlike structure, especially a microscopic appendage that enables many protozoa, bacteria, spermatozoa, etc. to swim.The thread-like structure is called chromosomes.
This can conclude that microtubules are common in spindle fiber and flagella.
