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.

Why do we exhale more carbon dioxide than we inhale?

Answers

Answer:

When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.

Answer:

because our bodies take in O and put out  CO2

Explanation:

O is Oxygen

and CO2 is Carbon dioxide

Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above

Answers

Answer:

It's 3!

Explanation:

There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur

It's not 1 because a food shortage isn't required, there's always competition for food sources

It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.

And it can't be 4 if 1 and 2 are wrong!

in pea plants, purple are dominant to white.
complete the chart showing the genotypes and phenotypes possible.

someone help me i’m kinda lost on how i do this

Answers

Answer:

PP (genotype) - Purple (Phenotype)

Pp (Genotype - Purple (Phenotype)

pp (Genotype) - White (Phenotype)

Explanation:

The genotype allele combinations, in order to for purple to be dominant there are three possible genotypes

*Capital P represents a purple dominant allele

*Lowercase p represents a white recessive allele

(Alleles are the variants of a certain gene, ex: brown eyes, green eyes, etc. )

A Dominant always overpowers the recessive, the only way for a recessive to show would be to have two recessive alleles from both parents

ex: Green eyes recessive to Brown

B - Brown       bb = green eyes (from dad)  

b - green       bb = green eyes (from mom)  

this means that their child would have green eyes because there is no brown present

So for your pea plants to be purple

Pp = Purple      pp = white

PP = Purple    (yes there can be white recessive present, it just might not appear as a plant because of the percent of purple)

The colors or observations we see as the plant are the phenotypes

so the colors I have listed would be the phenotypes

Don't get alleles and phenotypes confused, alleles are the various forms of a gene, and phenotypes are what we see when the gene is brought through.

how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.

Answers

Answer:

Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.

The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

The diagram below shows two processes, P and Q, in the carbon cycle.



Which of these statements best describes the processes P and Q?

P shows diffusion and Q shows weathering.
P shows weathering and Q shows diffusion.
P represents combustion and Q represents decomposition.
P represents decomposition and Q represents combustion.

Answers

Answer:

P shows diffusion and Q shows weathering.

Explanation:

The process shown in the image attached to this question is a part of the carbon cycle. Based on the image in this question, atmospheric carbon enters the ocean in a process called P while carbon deposited in limestone is released into the atmosphere via a process called Q.

- Atmospheric carbon which is carbon dioxide (CO2) enters the surface of the ocean via a process called DIFFUSION, hence, process P shows diffusion

- Also, for the carbon in limestone to be released into the atmosphere, the limestone has to be broken down in a process called WEATHERING. Hence, process Q shows weathering.

⦁ Arrange these statements in the right order to describe process of inhalation.

____ Air is drawn into the lungs
____ Air pressure in the chest cavity decreases
____ Lungs expand
____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out

Answers

Answer:

air is drawn into the lungs

lungs expand

the muscles between the ribs contract to move the ribs up and down

air pressure in the chest cavity decreases

the diaphragm contracts and flattens

Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.

What is inhalation?

Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.

This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.

Therefore, the air is drawn inside the lungs in inhalation.

why do large organisms require a transport system?​

Answers

Answer:

Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.

Explanation:

Answer:

As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.
