Plants like the stinging nettle seen here have sharp, needle-like hairs that inject a burning chemical into animals that touch the stems or leaves. These hairs are used for A) protection. B) reproduction. C) photosynthesis. D) attracting insects.

Answers

Answer:

A. Protection

Explanation:

These plants have this external protection system to protect them against being eaten by these animals.

In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.

The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals

where is sugar removed and how can you tell​

Answers

Explanation:

What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.

    It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.

Explain the relationship between a hypothesis and a theory. Then give an example of something that would cause a hypothesis or a theory to be revised or discarded.

Answers

Answer:

Hypothesis is a written observation, that has not been proven correct, but is written after observation of a specimen. Proving this particular hypothesis, shows the interconnectivity/ relationship between a hypothesis and a theory.

Explanation:

Simply put, a hypothesis is a written observation, which may or may not be true, while a theory is established when a hypothesis is proven correct.

AN EXAMPLE OF SOMETHING THAT COULD MAKE A THEORY TO BE REVISED:

If other laws or theories put before it controversies it.If its observations where not correctly written.If it cannot stand the test of time.If further experiments doesn't show the same result.

Hypothesis is  either written or evidence based observation but it has to be proven where as when a hypothesis is proved by doing experiments multiple times and getting same results then it is called as as scientific theory.  

What is scientific theory ?

scientific theory can be  a structured form where a group of facts can meet and  be explained by using scientific hypothesis and laws, each theory can be proved by doing experiments and applying scientific method.

Scientist will design an experiment and conduct the experiment to test  and prove that hypothesis; If the result of hypothesis is incorrect, then new hypothesis will be set and new experiment will begin.

If the result of  hypothesis is correct, repeated tests  have been done to ensure the accuracy of the result.

Blue crabs get their name from their blue-tinted claws and are very popular type of crab. Many people harvest these crabs for meat. The number of blue crabs has decreased in the Chesapeake Bay because of over- harvesting and changes to their habitat.

D. Embryo development

Answers

Answer:

Answer is A, Homologous Structures

Explanation:

The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures. Option A is correct.

Homologous structures:

These are the structures in the different organisms that show similarities in the basic organization of the structure.

These organisms are from common ancestors, Homologous structures serve completely different functions.For example- The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants.

Analogous structures are those structures that serve the same function but are from different ancestors.

Therefore, The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures.

Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.

Answers

Answer:

C. Electromagnetic energy is transformed into chemical energy

Explanation:

Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.

This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.

it is C.  Electromagnetic energy is transformed into chemical energy.
