Which of the following is true about CO_2CO
2
?
A
It does not have much effect on the climate.
B
It is a greenhouse gas.
C
Very little CO_2CO
2
is being emitted now.
D
If we cut CO_2CO
2
emissions by half, the temperature will stop rising.
Answer:
B.
Explanation:
It has a huge impact on the environment
It is being emitted in large amounts
And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.
But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.
CO2 is a greenhouse gas.
what are greenhouse gases?
Greenhouse gases are gases in the atmosphere that affect the energy balance of the planet. The greenhouse effect is caused by them. Carbon dioxide (CO2), methane, and nitrous oxide, the most well-known greenhouse gases, can all be present in low concentrations in the environment.
The greenhouse gases in the atmosphere trap heat and warm the earth.
Carbon dioxide, methane, nitrous oxide, and water vapor (all of which exist naturally) are the principal greenhouse gases, as are fluorinated gases (which are synthetic).
Carbon dioxide (CO2) is released into the atmosphere as a result of the combustion of fossil fuels (coal, natural gas, and oil), solid waste, trees, and other biological materials, as well as chemical processes (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is absorbed by plants and released from the atmosphere.
hence, CO2 is a greenhouse gas.

5. What would be the effect if a gene has a mutation in the location of the stop codon? (4 points)
During translation protein synthesis won't stop when it should so amino acids will continue to be placed and the peptide will be bigger.
Answer:
In genetics, a point-nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a point-nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product.
How does the double helix structure of DNA support its role in encoding the genome?
1)The sugar-phosphate backbone provides a template for DNA replication
2)tRNA pairing with the template strand creates proteins encoded by the genome
3)Complementary base-pairing creates a very stable structure
4)Complimentary base pairing allows for easy editing of both strands of DNA
Answer: Complementary base- pairing creates a very stable structure
Explanation:
The double helix structure of deoxyribonucleic acid (DNA) support its role in encoding a genome because the: 3. Complementary base-pairing creates a very stable structure.
A double helix can be defined as the spiral configuration of the deoxyribonucleic acid (DNA) molecule.
In Biology, a double helix is typically used to describe the molecular structure of a double-stranded deoxyribonucleic acid (DNA) molecule, which comprises two (2) linear strands that are complimentary and run opposite to each other and twist together (anti-parallel).
Hence, the complementary base-pairing in a double-stranded deoxyribonucleic acid (DNA) or double helix structure of deoxyribonucleic acid (DNA) helps to create a very stable structure, which in turn makes it possible to encode a genome.

The stage of spinal shock that follows spinal cord injury is characterized by a. absent spinal reflexes below the level of injury. b. autonomic dysreflexia. c. motor spasticity and hyperreflexia below the level of injury. d. reflex urination and defecation.
Answer:
The correct answer is a. absent spinal reflexes below the level of injury.
Explanation:
Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.

Fish are considered carbon-based organism
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth can be thought of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
What is the pH of a 2.4 x 10-5 M
OH-solution?
Answer: pH = 9.4
Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14
-log(H+) is pH
so pH = 14 - -log(OH-)
= 14 - -log(2.4*10^-5)
= 14 - 4.6
= 9.4

A botanist finds that when compared to pink flowers, the population of purple flowers is very high. Ten years later, the population of purple flowers is nearly gone, and the number of pink flowers has tripled. Why would this be?
Answer:
Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.
Explanation:
From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:
1. Disease and pest attack on the purple flowers.
2. The pink flowers developed a good survival mechanism even in adverse conditions.
3. Environmental stress could also come into play on the purple flowers.
4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.

What is the process of Asexual reproduction? Honey Bees
And
What is the process of Sexual reproduction? Honey Bees
Answer:
ASEXUAL
female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees. The team sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees that reproduce normally.
SEXUAL
The typical story of reproduction is that males and females of an animal species do it sexually. Generally, that's what honeybees do, too. Sperm from a male drone fertilizes a queen's eggs, and she sends out a chemical signal, or pheromone, that renders worker bees, which are all female, sterile when they detect it.

What would be the expected response to a skin injury if the involved tissue had lost the normal cell characteristic of contact inhibition
Answer:
uncontrolled excessive growth of cells in the tissue
Explanation:
Contact inhibition is a cellular mechanism where cell growth is arrested when adjacent cells are in contact with each other. Contact inhibition serves to arrest further cell growth beyond a monolayer, by limiting the migration and/or proliferation of cells in a tissue or organ. In consequence, contact inhibition is critical for normal cells to stop proliferating. When contact inhibition is disrupted, cells undergo uncontrolled growth, which leads to the development of cancer and tumor progression.
