List 5 changes that could be made in your community that could
help protect the environment.

Answers

Answer:

-distribute energy grids

-recyling manufacturers for recycling resources that are not just plastic

-composting food waste to produce nutrient dense soil for crops

-conserving water= using it only when its needed

-walking biking or taking public transport instead of a car to reduce pollution and traffic amongst the streets

1) Reduce, reuse, and recycle. Cut down on what you throw away. Follow the three "R's" to conserve natural resources and landfill space.

2) Volunteer. Volunteer for cleanups in your community. You can get involved in protecting your watershed, too.

3) Educate. When you further your own education, you can help others understand the importance and value of our natural resources.

4) Conserve water. The less water you use, the less runoff and wastewater that eventually end up in the ocean.

5)Use long-lasting light bulbs. Energy efficient light bulbs reduce greenhouse gas emissions. Also flip the light switch off when you leave the room!

How do you explain that the variability in a domesticated species is greater than in the same species, or a similar one, in the wild? For example: dogs vs. wolves; chickens vs. red jungle fowl.

Answers

Explanation:

i believe it is because the domesticated breeds were bred specifically through generations in order to serve a specific purpose, for example dogs could be bred for hunting or herding, etc and chickens could be bred for eggs or meat, etc. but in the wild, their only job is to survive and reproduce.

As a seedling , the strangler fig and host tree have a relationship that is described as commensalism . Why is commensalism a good description for this relationship ?

Answers

Answer:

It merely uses the host tree to get closer to the sunlight and rain, and finds nutrients in decaying leaves and soil caught in nooks of the host tree's branches . This is a case of commensalism: one organism benefits while the other is unaffected.

Explanation:

The relationship between the strangler fig and a host tree would be described as commensalism because the strangler benefits from the relationship while the host tree is unaffected.

Commensalism refers to a relationship between two organisms in which one of them (the commensal) benefits and the other (the host) is unaffected in any way.

As a seedling, the strangler fig grows harmlessly around the a host tree. As the seedling develops to a more mature plant, it starts extending its branches and roots around the host plant, eventually strangulating the host plant.

The graph below shows drug levels in the blood and in a target organ through time, while taking Pill Type C in the Gizmo. The dosage schedule is one pill every two hours. What will eventually happen if the patient continues to take the pill on the same dosage schedule?

Answers

Answer:

I don't know man

Explanation:

Answer:

Correct Answer: B. The drug level in the target organ will level off and reach equilibrium.

Explanation:

As long as the dosage schedule is maintained, the drug level in the target organ and blood will stabilize. The reason for this is that as the concentration of drug increases in the organ and blood, the amount of drug removed by the kidneys increases as well, as each cubic centimeter of liquid removed from the blood by the kidneys contains a greater amount of drug. Eventually, the amount of drug removed in the time period between pills is equal to the amount that is added with each pill. As the graph below shows, the maximum organ drug level in this example is about 192 mcg/cc.

C.
Protozoans can be heterotrophic or autotrophic.

D.
Protozoans can be unicellular or multicellular.

Answers

Answer:

pretty sure that its c

Explanation:

Answer:

B

Explanation:

Answer B is correct:

Because the biologists are continuing to learn more and more about

such minute organisms, protozoan systematics – that is,  the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a  topic of debate and change, still today.

Some of the rather  LARGE and unwieldy taxonomic groupings of past years are  particularly subject to revision with expansion of and  refinement in the knowledge about the members of those –  and related – assemblages. Paradoxically, the protozoa  themselves are becoming more difficult to define with  precision as our information about them and other microbial assemblages increases. Thus, presenting a single  satisfactory circumscribed definition for them is not an  easy task.

...

Answer A sounds so funny.

Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

When Mendel crossed tall pea plants with short pea plants all of the offspring were tall. Which of the following explains the tall gene?
A) The tall gene is peas is recessive
C) The short gene is peas is dominant
B) The short gene in peas is recessive
D) The tall gene in peas is dominant

Answers

Answer: D: The tall gene in peas is dominant

Explanation:

When alleles are heterozygous, dominant genes will "overpower" the recessive gene.

The offspring in the pea plants had both alleles of the gene, but despite this, all of the pea plants were tall. This is because the dominant gene, the tall gene, was expressed over the recessive gene.

The correct answer is D.

B is also correct, but the question asks us to explain the tall gene, not the short one.

D The tall gene in peas is dominant

Explanation: The tall gene in the peas is dominant while the short gene in the peas is recessive otherwise most of the offsprings would be short

O C. To filter out fiber and bacteria and send them to the large intestine
O D. To filter out salts and fats and send them to the urinary bladder

Answers

Answer:

D. To filter out salts and fats and send them to the urinary bladder

Explanation:

Kidney is an excretory organ in the systems of certain living organisms e.g humans. It is a bean-shaped organ responsible for getting rid of waste products in our body via urine and maintaining homeostasis in the body.

Among the many excretory functions of the kidney, they help filter out electrolytes e.g salts and fats out of the blood and pass them to the urinary bladder through tubes called ureter. The waste products are eventually passed out as urine from the bladder.
