These changes can be natural, such as through variations in the solar cycle.

<h3>Climate history</h3>

Clam shells

2. 800,000 years ago

Ice cores

1. 150 million years ago

Oldest rocks in the world

5. 3.8 billion years ago

Tree cores

3. 10,000 years ago

Ocean sediments

4. 200 million years ago

With this information we can conclude that these changes may be natural, such as through variations in the solar cycle. But since 1800, human activities have been the main driver of climate change, mainly due to the burning of fossil fuels like coal, oil and gas.

All enterics are facultative anaerobes; they have both respiratory and fermentative enzymes. What color results would you expect
Andrej [43]

Answer:

Explanation:

The O-F glucose test (oxidative-fermentation) is used to determine whether an organism is performs oxidative or fermentative metabolism.

Oxidative metabolism (i.e respiration) takes place in the presence of oxygen while fermentative takes place in the absence of oxygen.

Facultative anaerobes can carry out both fermentation and respiration.

The O-F medium has glucose, peptones and a pH indicator. When the pH of the medium is acidic, that is glucose has been broken down, the medium turns yellow. When it is basic, it turns blue implying that peptone and not glucose had been broken down.

The sealed tube is overlaid with oil so as to prevent oxygen from getting in, making it anaerobic.

The unsealed tube allows oxygen.

Enterics would be yellow is both tubes because they are facultative anaerobes and can grow in the presence or absence of oxygen, hence they carry out both respiration and fermentation.

Why does passive transport matter?
adell [148]

Answer:The most direct forms of membrane transport are passive. Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.

Hypothesize how some people have red hair through viable errors. Explain your answer in 1-2 sentences.
DENIUS [597]

Considering a viable error as a mutation that remains viable for the continuation of life, we can confirm that some people have red hair through viable errors due to mutations in the genetic code.

A viable error or mutation would be any mutation that allows the cell in question to stay alive. This is because there are mutations in which <em><u>key features or processes essential to life are altered. </u></em>

The cells that suffer these mutations would not be able to sustain life. The mutation that causes red hair is a mutation in the gene responsible for melanin (the pigment that gives hair its color) is <u>not one that affects an essential process.</u>

<u />

For this reason, we can confirm that some people have red hair through viable errors given that these errors or mutations do not affect mechanisms <em><u>essential </u></em>to life.
