How does a forest fire impact a population of birds that nest in the trees.

Answers

Answer:

If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.

Assuming birds escape a fire, smoke might still affect their health in ways that aren’t very well understood. Scientists have found that smoke can damage lung tissue and leave the animals susceptible to potentially lethal respiratory infections.

John and Marissa purchase their first home for $120,000. They must put 15 percent down on the purchase price as a down payment. What will the amount of the down payment be?

Answers

Answer:

Downpayment: 15% of original price

Original price: $120,000

15% of 120,000 = [tex]\frac{15}{100}[/tex] × 120,000

                          = $18,000

Thus, the downpayment is $18,000.

John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price

Original price: $120,000

15% of 120,000 =  × 12 = $18,000

Thus, the downpayment is $18,000.

What is down payment?

Part A

The down payment of $48,000 is 20% of the purchase price

Part B

A $12,000 down payment will be 5% of the purchase price

A percentage is the expression of the product of the ratio of two numbers and 100

The amount the investors buy the studio apartment = $240,000

The amount the investors have as down payment = $48,000

Part A

The ratio of the down payment the investors have and the amount the investors buy the apartment = 45,000/240,00 = 0.2

Therefore, their down payment is 0.2×100 = 20% percentage of their purchase price

Their $48,000 down payment is 20% of their purchase price

Part B

The percentage of the purchase price a $12,000 down payment would be is given as follows;

12,000/240,000 × 100 = 5%

Therefore, a $12,000 down payment will be 5% of the purchase price.

John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price

Original price: $120,000

15% of 120,000 =  × 12 = $18,000

Thus, the down payment is $18,000.

a scientist finds an organism that has a single cell without a nucleus this organism was found in pond water in which kingdom does it belong to? explain what is the answer if you find the answer i will give you 100,000 dollars

Answers

Answer:

Protista

Explanation:

In biology, there are said to be six different kingdoms that an organism can be classified under. They include Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria.

With this in mind, you say that a unicellular (single-celled) organism without a nucleus was found in pond water. This would point to the Protista kingdom, which are also known as protists. These organisms are single-celled beings with no big nucleus that are typically found in environments like ponds.

what processes in your cells produce the co2 that you exhale?

Answers

Answer:

Co2 is released from the pyruvate that is formed during glycolysis, and CO2 is also released during the citric acid cycle.

Explanation:

Cellular respiration in mitochondria produces [tex]CO_2[/tex] as a waste product, exhaled during breathing.

Cellular respiration occurs mostly in mitochondria. During cellular respiration, glucose and other nutrients are broken down to make ATP. This procedure produces [tex]CO_2[/tex]. [tex]CO_2[/tex] from mitochondria diffuses into the circulation.

Breathing exchanges [tex]CO_2[/tex] for oxygen in the lungs from the circulation. Your body releases [tex]CO_2[/tex] when you exhale. This important cycle eliminates unwanted [tex]CO_2[/tex] and supplies cells with oxygen for respiration and energy generation.

Stem cells can be developed into a required tissue because of their ability of cellular DIFFERENTIATION. These cells can develop specialized cells.

Stem cells are cells that can develop into specialized types of cells in order to perform specific functions.

The process of cellular differentiation from stem cells involves differential gene expression patterns, a cellular process that leads to the development of distinct types of cells.
