Seeds that are planted upside down are still able to grow into mature plants. Which explanation
best explains this phenomenon (a)The roots change into branches in the branches turn to roots(b) The roots grow towards the force of gravity and the stem goes away(c)The plant will become a smaller version of a mature plant(d) roots always grow toward the dark and the stem grows toward the light

Answers

The explanation that best explains this phenomenon is: the roots grow towards the force of gravity and the stem goes away

WHAT IS GEOTROPISM?

The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant.

When a seed germinates, the root part of that seed grows towards gravity i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.

Hence, if a seed is planted upside down, it will still grow into an erect mature plant because the root will grow downwards towards gravity (positive geotropism) while the stem grows upward away from gravity (negative geotropism).

What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?

Answers

Answer for you
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

How does this equation represent the law of conservation of energy—that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.

Answers

Answer:

Energy from the sun goes into making the sugar molecule. This energy is released to make ATP and heat.

Explanation:

6Co2+6H20->C6H12O6(glucose)+6O2(oxygen)

The sugar molecule is created by solar energy. This energy is discharged to produce heat and ATP.

What is the law of conservation of energy?

According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be generated or destroyed.

This indicates that unless energy is introduced from the outside, a system always has the same quantity of energy. In the situation of non-conservative forces, when energy is changed from mechanical energy to thermal energy yet the overall energy does not change, this is especially perplexing. Energy must be changed from one form to another in order to be used.

In photosynthesis,

6CO + 6H₂O → C₆H₁₂O₆ + 6O₂

Sunlight is used for the light energy required to produce the sugar molecule.

Therefore, the law of conservation of energy is applicable in photosynthesis as energy from the sun is utilized by all living organisms.
