1 3
2 1.8
3 1.08


Jessa wants to find the sum of the length of string after 10 throws. Choose the answer that shows the sum of the lengths rounded to the nearest hundredth.

A. 0.03 foot
B. 2.50 feet
C. 7.50 feet
D. 7.45 feet

Answers

The general formula for a geometric sequence can be written as: 
a(n) = a r^(n-1) 

a = first term = 3 
r = common ratio = 0.6 
n = number of terms = 10

substituting the values:

a(n) = 3 * (0.6)^(10-1)
a(n) = 3 * (0.6)^9 
a(10) = 0.030

Sum of the ten terms = 3 (1-0.6^10)/1-0.6
                                   = 2.98/0.4
                                   = 7.45

7.45

Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. What would most likely happen to the legume population if Rhizobia suddenly became extinct?

Answers

Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.

What are legumes?

A legume is a plant from the family of fabaceae, they are basically pulses that are the rich source of protein. Legumes are grown agriculturally, primarily for human consumption, for living and forage and silage.

Legumes are chickpeas, peanuts, green peas, black beans, kidney beans, navy beans and lima beans.

Legumes are plants refers to a plant from the family fabaceae that would include leaves, stems, and pods.

Rhizobium is a gram- negative soil bacteria that fix nitrogen in the soil and they are also known as nitrogen fixing bacteria and they help to fix nitrogen of soil during the process of photosynthesis.

The rhizobium is from class alphaproteobacteria, Genus rhizobium and order hyphomicrobiales, phylum pseudomonadota and domain bacteria.

Therefore,Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen during photosynthesis. Rhizobia use the legumes for food. If Rhizobia suddenly became extinct the legumes become extinct too because for the growth of legumes rhizobia is required and if they are extinct than legumes also extincted.

The answer is: the legumes will extinct, too.


It is known that plants cannot directly use atmospheric nitrogen. But, some legumes have a symbiotic relationship with bacteria that live in their root system. These bacteria are called Rhizobia and have the ability of nitrogen-fixation. In the root nodules, they use atmospheric nitrogen to convert it into ammonia, and later to ammonium, which can be used by plants. When legumes die, nitrogen from their remaining is released back to the soil where it is available to the other plants.

So, if Rhizobia suddenly became extinct, the symbiotic relationship between will be interrupted. The legumes will not be able to use atmospheric nitrogen without the help of Rhizobia, and eventually, they will extinct, too.

Answers

Answer:1.) is LAW and 2.) is experiment

Explanation: i already did this

Final answer:

A theory is an accepted explanation of an observed phenomenon supported by empirical data, whereas the scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses.

Explanation:

1.) A theory is an accepted explanation of an observed phenomenon supported by empirical data. For example, the theory of evolution is an accepted explanation of the observed changes in species over time, based on a wealth of empirical evidence from biology, geology, and other fields. 2.) The scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses. This process includes making an observation, asking a question, doing research, constructing a hypothesis, testing the hypothesis through experimentation, analyzing data, and drawing a conclusion.
