As plants diverged from a common ancestor, characteristic features evolved that distinguished
the main plant groups from one another. Which statement shows the evolutionary sequence in
which these features developed?
A. vascular tissue, seeds, flowers
B. seeds, vascular tissue, flowers
C. flowers, seeds, vascular tissue

Answers

The statement 'vascular tissue, seeds, flowers' shows the evolutionary sequence in which plant features developed (Option A).

What is evolution?

Evolution means descendence with modification, which mainly occurs due to natural selection.

In terrestrial plants, the main evolutionary feature that emerged was the appearance of vascular tissues.

Subsequently, terrestrial plants evolved to produce seed plants and then flowers (angiosperm plants).

Which chemical compund is formed during photosynthesis ?

Answers

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

Answers

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.

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.

Decreased water quality, increased pollution, depletion of natural resources and global climate change are the results of human land use.

How human impacted the environment?

Humans impact the environment in many ways such as overpopulation, pollution, burning fossil fuels, and deforestation. Human activities triggered climate change, soil erosion, poor air quality, and undrinkable water.

So we can conclude that reduction of water quality, increased pollution, depletion of natural resources and global climate change are the results of human land use.

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?

Answers

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 × time

In 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.
