Jaden’s mass is 50 kilograms. His weight on Earth is

Answers

Answer:

Weight of the Jaden on earth is 490 N.

Explanation:

Formula

w = mg

Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .

Gravity on Earth is 9.8 m/s² .

Jaden’s mass is 50 kilograms.

g = 9.8 m /s²

m = 50

Put the values in the formula

Thus

w = 50 × 9.8

  = 490 kg m /s²

(As N = kg m/ s²)

  = 490 N

Therefore the weight of the Jaden on earth is 490 N.

Rice is an important food crop in the the world. Growing rice requires large amounts of water because the roots of rice plants must remain under water. Explain how genes could play a role in helping farmers grow rice using less water. 2 sentences, explain they could do (answerrrr ASAP)

Answers

Answer:

Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.

Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.

The genetically modified rice plant then do not require large amount of water and can grow easily.

There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.

Two main challenges conservationists will face while monitoring population of organisms in wild are:

weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.

Hence, conservationists face the above challenges while dealing with wild.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria

Answers

Answer:

A.The bacteria in the culture tube were already dead when you made the plate

Explanation:

Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.

Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.

There can be several interpretation for the absence of bacteria such as:

The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.

Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.

So, the correct option is A.
