which statement correctly describes how the amount of ofoxygen in the earth’s atmosphere has changed over time?
Answer:
Based on the relative volumes of the gases in Earth’s atmosphere, nitrogen is actually more than 3 times more than oxygen. Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass.. From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2 and trace gases.

The birds on the old island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
D.
The birds on the new island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
Answer:
D.
Explanation:
because if the birds in figure A move to the new island with new food size and shape they will adapt to the food
The hours of daylight can vary greatly because of latitude. How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.
Answer:
Explanation:
The amount of daylight that is received is directly proportional to how close the sun is to each hemisphere. This happens due to Earth's inclined axis which changes as the Earth rotates and causes more daylight in the Northern or Southern hemispheres which is when summer starts in each. That being said the Equator is the only location that has an even amount of sunshine all year round. This is why it is always hot and Equator cultures only recognize dry and wet seasons but still consider it summer all year round.

3. The sequence of nitrogenous bases is unique to each organism. The sequence of the
bases in DNA is most important for which of the following?
Random mutations may occur because a change in the order of nitrogen bases in a codon. One type of mutation involves a substitution of one of the nitrogen bases in a codon. What amino acid is called for by GGA codon?
Answer:
Alanine
Explanation:
Using the codon chart (see the attached image), that is, a chart of triplet codes and the corresponding amino acids that they represent, the amino acid called for by GCA codon is alanine.
There are 64 possible codons in nature from 4 nitrogen bases - adenine (A), guanine (G), cytosine (C), and uracil (U). The codes are degenerates because they represent only 20 naturally occurring amino acids. Hence, more than one codons codes for each amino acid. Apart from GCA, other codons that translate as alanine include GCU, GCC, and GCG.

10. Deafness in cocker spaniels is inherited. The allele for deafness (d) is recessive to the allele for hearing (D). Two cocker spaniels that are heterozygous for hearing are mated together. What is the chance that a puppy will be deaf?
Question 10 options:
0%
25%
50%
100%
Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
The chance that the puppy will be deaf is 25%. The correct option is B.
What is allele?The term "allele" refers to the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to categorize the alleles.
We usually refer to them as normal or wild-type alleles, or abnormal or mutant alleles.
If they are both heterozygous, they have the Dd genotype. As per the Punnett square Dd x Dd, one can see the the following genotypes for the puppy:
DD, Dd, dD, dd
Because deafness is recessive, the puppy must be dd, which is 1/4 of the population.
Thus, the correct option is B.

What 2 chemicals are inside skeletal muscle?
Answer:
Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber.
The 2 chemicals inside skeletal muscle are : i) Organophosphate ( OP ) and ii) Acetylcholine ( ACh )
The skeletal muscle is toxic in nature due to the presence of certain chemicals ( Organophosphate and Acetylcholine ). and this causes the skeletal muscle to experience some level of toxicity. some of the toxic effects caused by the presence of these chemicals in the skeletal muscle include :
weakness of the muscle.partial/complete paralysis.muscle hyperactivity.Hence we can conclude that the 2 chemicals that can be found inside skeletal muscle are Organophosphate ( OP ) and Acetylcholine ( ACh )

BB, Bb and bb are examples of?
dominant
recessive
genotypes
phenotypes
BB, Bb and bb are examples of genotypes. Thus, the correct answer is genotype.
A genotype is the genetic constitution of a trait in an individual. It is the genotype that results in the particular phenotype. Phenotype is the observable result of the trait.
Capital letter indicates that the allele is dominant and for recessive allele, small letter is used. Thus, B indicates dominant allele of that trait and b indicates recessive allele for that trait.
Depending on the genotype, the individual can be homozygous dominant, homozygous recessive or heterozygous for a trait.
In this case, BB is for denoting homozygous dominant, Bb is for heterozygous dominant and bb is for homozygous recessive.

For a certain plant, purple flowers (allele: P) are dominant and white flowers (allele: p) are recessive. A heterozygous purple plant is crossed with a true-breeding (purebred) white plant. What are the possible genotypes (allele pairs) of the offspring?
The possible genotype of all the offspring will be PP, and Pp as per the given situation.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.
The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.
Thus, the possible genotype will be 50% PP and 50% Pp.

C) Evaporation and condensation
D) Evaporation and precipitation
Answer:
D
Explanation:
I took the test for flvs, it was correct.
The process that directly connect the ocean to the water cycle is evaporation and precipitation. The correct option is D.
What is water cycle?The water cycle is a biogeochemical cycle that describes the continuous movement of water on, above, and below the Earth's surface. It is also known as the hydrologic cycle or the hydrological cycle.
The water cycle depicts the continuous movement of water within the Earth's and atmosphere's atmosphere.
It is a complicated system with numerous processes. Liquid water evaporates into water vapour, condenses into clouds, and falls back to earth as rain and snow.
The water cycle describes the exchange (cycling) of water through Earth's land, ocean, and atmosphere. Evaporation and precipitation are the processes that directly connect the ocean to the water cycle.
Thus, the correct option is D.

Researchers are investigating the use of gene therapy as a treatment option for human genetic disorders, such as cystic fibrosis. When gene therapy is successful, how does it treat the disorder?
A. by activating, or "turning on," one or more genes
B. by deactivating, or "turning off," one or more genes
C. by incorporating a human gene into the genomes of bacteria or other organisms
D. by replacing a faulty gene with a normal gene in the human genome
Answer:
A
Explanation:
By replacing a faulty gene with a normal gene in the human genome. Therefore, option (D) is correct.
Gene therapy works by inserting a functioning gene into a patient's cells. A viral vector or other delivery method transports the normal gene into target cells.
In cells, the normal gene integrates into the genome and produces the functional protein that was missing or faulty in genetic disorder patients. Gene therapy replaces the damaged gene with a normal gene to repair the genetic origin of the condition and restore normal cell or tissue function.
