Answer:
The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.
Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.
Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.

Which statement describes Mendel’s hypotheses regarding gametes?
A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.
Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
Thus, option B) is the right answer.

If you are pushing on a box with
5N, and the box pushes back 5N,
what would the net force be?.
ΑΟ
A. ON
B. 25N
C. 10N
The correct answer is A. 0N, as there is no net force acting on the box.
The net force in this scenario can be determined by calculating the difference between the applied force and the opposing force. In this case, if you are pushing on a box with a force of 5N, and the box pushes back with an equal force of 5N, the net force would be zero.
Net force is the vector sum of all the forces acting on an object. In this situation, the applied force of 5N is countered by the opposing force of 5N exerted by the box. Since the forces are equal in magnitude and opposite in direction, they cancel each other out.
When the net force is zero, it means that the forces are balanced, resulting in no acceleration or movement of the object. The box would remain at rest or continue moving at a constant velocity if it was already in motion.
Therefore, the correct answer is A. 0N, as there is no net force acting on the box.

X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?
Answer:
can reveal the precise three-dimensional positions of most atoms in a protein molecule because x-rays and covalent bonds have similar wavelength, and therefore currently provides the best visualization of protein structure.
Because x-rays and covalent bonds have comparable wavelengths, they can now give the finest imaging of protein structure because they can reveal the precise three-dimensional locations of the majority of atoms in a protein molecule.
What is X-ray crystallography?
X-ray, a scientific technique called crystallography may be used to map out the atoms of a crystalline material in three dimensions. By using most crystalline materials' interatomic gap as a diffraction gradient for x-ray radiation, which has wavelengths on the order of 1 angstrom, this method makes use of the interatomic spacing of most crystalline solids.
Wilhelm Rontgen made the discovery of x-rays in 1895. Up until 1912, there remained disagreement about whether x-rays constituted electromagnetic energy or particles. Researchers recognized that this light's wavelength would need to be in the range of 1 Angstrom (A) if the wave theory was accurate.
It would be necessary to use a gradient with separation on the same order of magnitude as the light for diffraction and measurement of such tiny wavelengths.
To diffract the x-ray beams, the arrangement of the atoms must be in an ordered, periodic form. The specific arrangement of atoms in that crystal is then revealed through a sequence of mathematical computations to create a diffraction pattern. The principal technique still in use today for studying the structure and bonding of organometallic compounds is X-ray crystallography.
Therefore, since x-rays and covalent bonds can display the precise three-dimensional locations of the majority of atoms in a protein molecule, they provide the best imaging of protein structure currently achievable.

Explanation:
Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).

Answer:
A
Explanation:
Choose one biogeochemical cycle and explain.
A researcher dried a feedstuff and determined that it contained 10 percent moisture. he took 1 gram (dry) of it and combusted it in the bomb calorimeter. the calorimeter contains 1 kg of water. The temperature was raised 2.7 degrees centigrade. Two kilograms (2000 grams) of dry matter of the material was fed to a pig each day for several days. the fecal collections of the pig averaged 200 grams dried per day for the last few days. the feedstuff analyzed 2.41 percent nitrogen (dry basis); the feces (dry basis) analyzed 4.6 percent nitrogen. (hint: the feedstuff contained _____ grams protein, the feces contained _____ grams protein.)
Answer:
Explanation:
The objective of the information given is to calculate the apparent digestible dry matter present in the feedstuff(%) and the apparent digestibility of the protein?
From the given information:
The apparent digestible dry matter present is:
[tex]=\dfrac{ (\text{Dry matter fed to the pig} - \text{Fecal matter of the pig} )}{\text{Dry matter fed to the pig}} \times 100 \%[/tex]
where;
Dry matter fed to the pig = 2kg = 2000 g
Fecal matter of the pig = 200
∴
The apparent digestible dry matter present = [tex]\dfrac{2000-200}{2000}\times 100\%[/tex]
[tex]=\dfrac{1800}{2000}\times 100\%[/tex]
= 90
Amount of Nitrogen(i.e. the protein) content present in the feedstuff = 2.41%
i.e.
2.41 g/100 g OR 48.2 g/2000 g feed
Amount of protein present in feces = 4.6% (4.6 g/100 g OR 9.2g/200g of feed)
∴
apparent digestibility of the protein is:[tex]=\dfrac{\text{Amount in feed }- \text{Amount in feces}}{\text{Amount in feed }}\times 100[/tex]
[tex]= \dfrac{(48.2 - 9.2)}{48.2}\times 100[/tex]
[tex]= \dfrac{39}{48.2}\times 100[/tex]
= 81%

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers
Answer:
nose
Explanation:
nosenosenosenosenosenosenosenosenosenosenose
The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.
In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).
In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.
Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.
