please I need help immediately, describe an experiment to verify the living organisms in the soil.
Answer:
Soil living organisms compromise from mammals (such as rats) to micro organisms (such as nematodes and protozoa). Soil organisms help in the modification of soil, and also in the decomposition of organic matter. However they can also pose as a treat to to some crops, as they are responsible for some plant diseases.
Explanation:
When living organisms breathe they give out carbon dioxide gas as a waste product. Carbon dioxide gas can be detected (identified) using a carbon dioxide indicator solution called bromothymol blue. To find out if there are living organisms present in the four different levels of soil takenfrom the deciduous forest.

An individual invested $5,000 into two accounts. They placed part of it into an account that earned 4.5% and the rest in an account that earned 6%. The total annual income generated from this investment in simple interest was $270. How much was invested in each account?
Based on the total annual income from simple interest, $2000 was invested in Account 1 while $3000 was invested in Account 2.
What is simple interest?Simple interest the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest = Principal × rate × timeIn simple interest, the principal amount is always the same.
Given that the principal is $5000
This amount was invested into two account at the following rates:
Account 1 at 4.5% interest rate
Account 2 at 6% interest rate
Total income from simple interest = $250
Let amount invested in Account 1 be y; amount invested in Account 2 will be 5000 - y
Interest on Account 1 = y × 4.5% × 1 = 0.045y
Interest on Account 2 = (5000 - y) × 6% × 1 = 300 - 0
06y
0.045 y - 0.06y + 300 = 270
-0.015 y = -30
y = 2000
5000 - y = 3000
Therefore, $2000 was invested in Account 1 while $3000 was invested in Account 2.

Which chemical compund is formed during photosynthesis ?
Answer: carbon dioxide / CO2
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose

Proximal convoluted tubule
Loop of Henley
None of the above
Proximal convoluted tubule is the part labeled from the above diagram of nephron.
What is nephron?The nephron is the small microscopic structural and functional unit of the kidney. It comprises of a renal corpuscle and a renal tubule. The renal corpuscle is composed of a tuft of capillaries which is refer to as the glomerulus and Bowman's capsule. The renal tubule extends from the capsule.
Therefore, The proximal convoluted tubule is a portion of kidney nephron between the loop of Henle and the collecting tubule.

What does the process of cellular respiration begin and end with?
a. oxygen, glucose
b. energy, glucose
c. glucose, energy
d. glucose, oxygen
Answer:
C. glucose, energy
Explanation:
Glucose is ‘raw material’ in cellular respiration. It passes through the glycolysis cycle, in the cytoplasm of the cell. This occurs in virtually all cells. In eukaryotic cells, with mitochondria, the product of glycolysis (usually pyruvate) is channeled to the organelle and pass through the Citric acid /Krebs cycle that produces even more ATPs than glycolysis.

At the molecular level, how do scientists know a new species has arisen?
Answer:
DNA sequencing has brought us the genetic species concept. In this model, species are defined by genetic isolation rather than reproductive isolation. Species may be more or less identical morphologically, but differences in DNA determine whether or not a population is a new species.

I. It is random.
II. It results from genetic mutations.
III. It only affects an individual in a population.
I, II, and III
I and II
II and III
I only
Answer: I and II
Explanation: so basically, when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities, Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.
