A trisomic kangaroo would have 25 chromosomes, and a double monosomic kangaroo would have 15 chromosomes in a somatic cell.
A nullisomic kangaroo would have 7 chromosomes, a triple disomic kangaroo would have 23 chromosomes, and a tetraploid kangaroo would have 32 chromosomes.
a) In a trisomic somatic cell, one of the homologous pairs of chromosomes would have an extra copy, resulting in a total of 17 chromosomes (8 homologous pairs + 1 extra copy).
In a double monosomic somatic cell, two homologous pairs of chromosomes would be missing, resulting in a total of 12 chromosomes (8 homologous pairs - 2 missing pairs).
b) In a nullisomic somatic cell, one of the homologous pairs of chromosomes would be completely missing, resulting in a total of 14 chromosomes (8 homologous pairs - 1 missing pair).
In a triple disomic somatic cell, one of the homologous pairs of chromosomes would have two extra copies, while another pair would have one extra copy, resulting in a total of 19 chromosomes (8 homologous pairs + 3 extra copies).
In a tetraploid somatic cell, there would be four sets of 8 homologous pairs of chromosomes, resulting in a total of 32 chromosomes (8 homologous pairs x 4 sets).
Therefore, the correct answer for a) is 25, 23, and 24 chromosomes, respectively, and b) is 14, 26, and 32 chromosomes, respectively, depending on the scenario.

Question
A kangaroo is a diploid animal that has 8 homologous pairs of chromosomes in a typical somatic cell. How many chromosomes would be in an
a. trisomic, double monosomic, somatic cell?
b. nullisomic, triple disomic, tetraploid cell?
The kangaroo would have 9 pairs of chromosomes or a total of 18 chromosomes.
Each homologous pair of chromosomes contains two chromosomes, so a diploid kangaroo with 8 homologous pairs of chromosomes would have a total of 16 chromosomes. However, the question does not provide information on how many additional chromosomes are present in this particular kangaroo, so we cannot determine the exact number of chromosomes. However, we do know that the kangaroo has an odd number of chromosomes, which means it has an extra chromosome in one of the pairs, resulting in a total of 9 pairs or 18 chromosomes.
Kangaroos, like all mammals, have two sets of chromosomes in their somatic cells, which means they are diploid organisms. Each set of chromosomes comes from one of the parents, and they contain the genetic information that determines the physical and biological characteristics of the kangaroo.
In a typical kangaroo somatic cell, there are 8 pairs of homologous chromosomes, which means that there are two copies of each chromosome. The chromosomes are said to be homologous because they carry the same genes in the same order, although the specific versions of those genes may differ.
However, it is important to note that the question does not provide information on how many additional chromosomes are present in this particular kangaroo. It only mentions the number of homologous pairs of chromosomes. Therefore, we can only infer that the kangaroo has an odd number of chromosomes, indicating that there is an extra chromosome in one of the pairs. This would result in a total of 9 pairs or 18 chromosomes in this particular kangaroo.

A student tries to push a refrigerator-sized box of textbooks safely across the classroom.
The box does not move. He asks for help from other students.
The box starts to move when the number of students shown in the image is pushing together.
Based on this information, what conclusion can be drawn?
The box has a mass greater than the combined mass of the first two students pushing.
The forces acting on the box became unbalanced when the third student started pushing.
The only force acting on the box is the push applied by the students.
When the third student started to push, the box’s mass decreased
Answer:
The forces acting on the box became unbalanced when the third student started pushing.
Explanation:
The horizontal forces, friction and applied, were balanced until more force was applied than friction. Mass can't increase or decrease.

What is EPA?The Environmental Protection Agency (EPA) is a federal agency of the United States government that was established in 1970 to protect human health and the environment. The EPA's mission is to ensure that all Americans have clean air to breathe, clean water to drink, and safe land to live and work on. The agency is responsible for setting and enforcing national standards for air and water quality, as well as for managing toxic waste and other pollutants.
The EPA also works with other federal agencies, states, tribes, and local governments to address environmental challenges, such as climate change, ozone depletion, and exposure to hazardous substances. The EPA uses a range of tools and programs, including research and development, regulation, partnerships, and education and outreach, to achieve its mission. The agency also provides information and technical assistance to help individuals, communities, and businesses protect the environment and public health.

the carbon cycle review of terms
Answer:
A solid line would represent point on the graph that actually are included in the solution, while points that lie on dash lines aren't included in the solution.
The carbon cycle takes place in the environment, where plants, herbivores, consumers, and decomposers are present and fix the carbon in the environment.
What is the carbon cycle?The carbon cycle is important for the environment because carbon is present in the animal cell, in food, etc., and the carbon cycle is present in the given diagram. Here, the plant takes in the atmospheric carbon dioxide shown in the arrow 1, and the carbon dioxide is released by the animals and plants shown in the arrow 2.
Arrow 3 explains the rabbit taking the carbon from the food source, the plant releases oxygen and arrow 4 explains the carbon released by the decomposers from the animals and plants; and arrow 5 shows the carbon converted into fossil fuels. Arrows 6 and 7 both explain the release of carbon dioxide while plants use it for food synthesis.
Hence, the carbon cycle takes place in the atmosphere, where plants, herbivores, consumers, and decomposers are present and fix the carbon in the environment.

With respect to normal base pairing, when a molecule of DNA replicates, thymine will most likely pair with 2 points
Answer: Adenine
Explanation:
The structure of the DNA double helix is complex in nature. There are two strands of DNA that are wound around each other. The nitrogenous bases are bonded with hydrogen bonding and base complementarity. According to the Chargaff's rule of base complementarity adenine always pairs with the thymine and guanine with cytosine. These nitrogenous bases are paired on the basis of hydrogen bonding. Adenine bonded with thymine through two hydrogen bonds whereas the cytosine pairs with guanine via three hydrogen bonds. During DNA denaturation these hydrogen bonds are broken whereas during DNA replication these hydrogen bonds are formed between the nitrogenous bases.
