How are the spines on a cactus different from the leaves on an oak tree?
1. They provide nutrient intake
2. They provide heat exchange
3. They reduce water loss
4. They reduce oxygen release

Answers

Answer 1

Answer:

3.

Explanation:

because normal leaves transpire and release water where as spine don't transpire

Answer 2
Answer:3.
Explanation: Cactus spines are basically modified leaves. They defend the cactus against herbivores but also assist in reducing water loss by reducing air flow to the cactus, which provides shade. And due to no leaves the cactus stems are what carry out photosynthesis. In simpler terms, the water on leaves can be lost due to evaporation, but cactus spines don’t.

Name some harmful substances found in cigarette smoke. How do these
substances affect the respiratory and the circulatory systems?​

Answers

There are more than 7,000 harmful chemicals in tobacco smoke, at least 250 are known to be harmful. Some of these chemicals are:

Nicotine
Formaldehyde
Lead
Arsenic
Ammonia
Radioactive elements such as Polonium-210
Benzene

How some of those chemicals affect the body:

Nicotine is highly addictive and can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood).

Symptoms for formaldehyde are watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation

High levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death.

Arsenic poisoning occurs over a brief period of time, symptoms may include vomiting, abdominal pain, encephalopathy, and watery diarrhea that contains blood. Long-term exposure can result in thickening of the skin, darker skin, abdominal pain, diarrhea, heart disease, numbness, and cancer.

High concentrations of ammonia in air causes immediate burning of the eyes, nose, throat and respiratory tract and can result in blindness, lung damage or death.

Tobacco smoke contains many chemicals that are harmful to both smokers and nonsmokers.

A can of antifreeze spills near a clump of Dryopteris dilatata, a type of fern. The chemical seeps into the ground, endangering the plant's roots. The plant roots grow as far away from the chemical as possible to absorb only fresh water and minerals.
During this process, the roots primarily work in conjunction with which system? a) The immune system to defend against the toxic chemicals
b) The vascular system to reduce the absorption and transport of toxic chemicals
c) The reproductive system to make more root cells
d) The digestive system to create enzymes that break down the toxic chemicals​

Answers

Answer:D

Explanation:

I got it right on my test

Dryopteris dilatata is in family Dryopteridaceae. The movement of plant away from spill the roots primarily work in conjunction with vascular system to reduce the absorption and transport of toxic chemicals.

What is Dryopteris dilatata?

Dryopteris dilatata is a fern mainly located in deciduous or semi-evergreen family, native of Europe.

It can be grown in most cool, moist and light shaded areas. It is also called as broad buckler-fern.

As to avoid antifreeze spills, the plant roots grow far away from the area of spill. During this process roots primarily work with vascular system to reduce absorption and transport of toxic chemicals.

Thus, the correct option is b.

Answers

Answer:

Original sentence: When new information does not support a scientific theory, the theory  may be revised or sometimes rejected.  

New changed sentence: When the results of the experiment do not support a hypothesis, the hypothesis must be revised or rejected to state a new scientific theory.

Explanation:

The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.

The theory is fundamental to science because it allows scientists to organize and understand observations.

The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.

A scientific theory is a knowledge that has been contrasted in several ways.
