Answer:

Growing new trees to replace old trees

Explanation:

Growing new trees in place of old ones sustains the environment, since trees help circulate oxygen and provide homes and nutrients for animals and other plants.

Any form of mining is bad for the environment and unsustainable in the long run, garbage is the same way, and putting it on land is only slightly better, and switching to other resources doesn't do anything but burn out more resources and does nothing to sustain anything.

The statement embryonic stage is the first phase of the prenatal stage, lasting only two weeks after conception is false.

An embryonic stage may be defined as the period after implantation, during which all of the major organs and structures within the growing mammal are formed.

The first two weeks after conception are known as the germinal stage, not the embryonic stage. The third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.

Therefore, the statement embryonic stage is the first phase of the prenatal stage, lasting only two weeks after conception is false.

Systemic circulation involves the movement of blood from the right ventricle of the heart to the cells of the body and back to the heart through the right atrium.

It is a form of blood circulation through which functional blood is supplied to all the cells and tissues of the body.

The system starts with oxygenated blood leaving the right side of the heart through the ventricle.

The blood travels through arteries to different cells/tissues of the body, supplies them with oxygen and vital nutrients, and picks up waste materials simultaneously.

Deoxygenated blood then travels through veins back to the heart through the right atrium.

Information about the four organisms can be found on the Internet. Use credible websites to find answers to the questions you developed in part A. Based on this data, draw your own dichotomous key. Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.

Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms. For example, Does the organism have cells? would be an inappropriate question, because all the organisms have cells.

If the solution becomes transparent we could assume that ;  The solution was hypotonic and the cells had burst.

To test for Tonicity of red blood cells, we placed the cells in a solution.When red blood cells are placed in hypotonic solution there is high rate of osmosis in which the solvent flows into the red cells placed in the solution the cells will experience a process known as Hemolysis and these cells do not diffuse light, the solution becomes a red transparent solution.

Hence we can conclude that If the solution becomes transparent we could assume that ;  The solution was hypotonic and the cells had burst.

Animals' belching, field burning, deforestation by burning, transportation products, and operating factories are the activities that emit greenhouse gases.

Many of the chemical elements that make up the atmosphere of the planet function as greenhouse gases. Some of the sunlight that touches the surface of the planet reflects back into space as infrared radiation (heat). This infrared radiation is absorbed by greenhouse gases, which trap the heat it contains in the atmosphere and causes global warming and climate change.

These greenhouse effects are seen in many gases. Some gases are created both naturally and by human activity. Some are entirely human-made, such as industrial gases. The most prevalent greenhouse gas is water vapor, although most scientists think that the quantity of water vapor in the atmosphere that is directly created by human activities is quite little.

Therefore, the activities that can produce greenhouse gases are animal belching, field burning, deforestation by burning, transportation products, and operating factories.

The kidney's intrinsic capacity to control blood flow gives the ability to regulate glomerular filtration.

Renal autoregulation is a mechanism that allows the kidneys to maintain constant blood flow and glomerular filtration rate (GFR). This is hugely important to keep homeostasis for several reasons:

Two mechanisms take part in Renal autoregulation:

In conclusion, blood flow and glomerular filtration are two hugely important factors in renal function and both can be regulated by the kidney itself via two mechanisms.

Answer:

A filter will absorb its complementary color of light. So a yellow filter absorbs blue light since blue is across from it on the color wheel. Whatever light is not absorbed will be transmitted; so yellow filters transmit red and green light (if incident upon it), also known as yellow light.

hope its helpful

A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.

A filter is a translucent substance that lets some colors flow through while absorbing others.

Color can only be produced by light. Color pigments (paints, dyes, or inks) display color by reflecting the light that isn't absorbed while absorbing some portions of the light spectrum.

The same principles govern how color filters function, with some color wavelengths being absorbed and others being transmitted.

Only yellow will pass through a yellow color filter while all other colors are absorbed. Therefore, if blue light is shone on a blue object through a blue filter, the object will still reflect blue and thus appear blue.

Therefore, A filter will absorb light of the complementary color. As blue is opposite yellow on the color wheel, a yellow filter will therefore absorb blue light.

The correct amino acids are brought to the ribosome by tRNA.

mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein is occurs during translation.

Translation is the procedure by which the mRNA codes for a specific protein. All the while, the ribosome interprets the mRNA created from DNA into a chain of explicit amino acids.

In the pathway of gene expression, protein synthesis is an essential process and a crucial control factor. Translation regulation is essential for maintaining homeostasis in both the cell and the organism and plays a prominent role in most cell processes.

Translation is the process of making a polypeptide chain from mRNA codons. tRNA charging, initiation, elongation, and termination are the four stages.

Answer:

disorder in the ecosystem

Explanation:

Invasive species are organisms from different ecosystems that somehow find their way to a different one. The ecosystem that they arrive in cannot be prepared to receive them and the invasive species, these species may not have predators or characteristics that help them to feed or reproduce quickly. This causes a disorder in the ecosystem that can wipe out entire species and if a species disappears in a chain many others will be affected.

Explanation:

In some plants, the pollen and stigma can come from the same flower or plant, which is known as self-pollination.
