Which visualization best helps the reader see the relationship between the two variables temperature and radiation why
Answer:
The correct answer is - scatter plot.
Explanation:
A Scatter plot is one of the visualization tools which is used to show or represent how much a single variable is affected by the other or what are the effects they have on one another. This visualization tool uses the position of dots on a graph to represent the values of variables.
Scatter plot helps in the show the relation or correlation of variables like temperature and radiation as they affect one other, if the dots are closer it means they have more correlation and vice versa.
Thus, the correct answer is - scatter plot.
Answer:
The scatter plot with the line of best fit (figure 4) is the most helpful in showing the reader the relationship between the two variables. It shows how the values relate to each other and also shows an approximation of that relation.

caleb has a double row of eyelashes that he inherited from his mother as a dominant trait. His maternal grandfather is the only other relative to have the trait . veronica, a women with normal lashes, falls madly in love with Caleb, and they marry. Their first child , molly, has normal eyelashes. Now veronica is pregnant again and hopes they will have a child with double eyelashes. what chance does their child have of inheriting a double row of eyelashes
Answer:
1/2 or 50%
Explanation:
From the illustration, the double row of eyelashes is a dominant trait.
Caleb inherited his double row eyelashes from his mother, meaning that Caleb is heterozygous.
Assuming that the allele for double eyelashes is represented by D, Caleb's genotype would be Dd.
Veronica has normal eyelashes, her genotype would be dd.
Dd x dd
Progeny Dd Dd dd dd
Probability of double eyelashes = 1/2 or 50%
Probability of normal eyelashes = 1/2 or 50%
Hence, the chance of their child inheriting a double row of eyelashes is 1/2 or 50%.
In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted pod shape (f). If two heterozygous plants (PpFf) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? _________________ X ____________________ What are the gametes for each p
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1

What global climatic change gave gymnosperms an advantage over ferns?
A) Increased fluctuations in global climate
B) the climate becoming hotter and wetter
C) the climate becoming cooler and drier
D) the climate becoming hotter and drier
The climate becoming hotter and drier which is the global climatic change gave gymnosperms an advantage over ferns. So, the correct option is D.
What are Gymnosperms?In contrast to angiosperms, or blooming plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms are described as any vascular plant that reproduces by an exposed seed, or ovule. Many gymnosperms bear their seeds in cones, which are known as "uncovered seeds" because they are not visible until they are fully developed.
Pinophyta, Cycadophyta, Ginkgophyta, and Gnetophyta are the four classes of gymnospermous plants, having 88 genera and more than 1,000 species among them. Gymnosperms have an advantage over ferns as a result of the temperature growing hotter and drier as a result of global climate change.
Therefore, the correct option is D.

You want to prepare a 1:50 dilution of your protein extract in a total volume of 1000 uL. You will need ___ uL of protein extract and ___ uL of water.
I’ll mark the brainliest!!
Answer:
20uL of protein, 980uL of water
Explanation:
According to the question, a protein extract is about to be prepared using a 1:50 dilution of the extract in a total volume of 1000uL.
1:50 means there will be;
1/50 part of protein and 49/50 part of water.
Hence, in a total volume of 1000uL, one would need:
Protein extract: 1/50 × 1000 = 20
Water: 49/50 × 1000 = 980
Therefore, 20uL of protein and 980uL of water will be needed to make a 1000uL solution containing protein extract and water in the ratio 1:50

Motor oil has different ratings depending on how readily it flows. This property depends on how much attraction is present between its particles. Which property of a liquid does this illustrate?
A. expandability
B. flexibility
C. surface tension
D. viscosity
Please let me know . Thank you!
Answer:flexibility
Explanation:
The property of a liquid that does illustrate the attraction present between its particles is the viscosity. Thus, the correct option for this question is D.
What is Viscosity?Viscosity may be defined as a type of physical property that significantly deals with the resistance of a fluid with respect to alteration in shape on the basis of the movement of neighboring portions relative to one another.
In a more simple sense, viscosity may be characterized as the estimation of the resistance of a fluid to processed deformation by shear or tensile stress.
According to the context of this question, motor oil has possess a different degree of viscosity which directly depends on how readily it flows. It illustrates a property that demonstrates the efficiency of attraction that is present between its particles.
Therefore, viscosity is the property of a liquid that does illustrate the attraction present between its particles. Thus, the correct option for this question is D.

What is the definition of a protein-binding site?Choose one:A. the region of the cell where proteins are assembled based on information from the genetic codeB. a pocket on a protein where a small molecule can be covalently attached and thus modify the proteinC. the portion of a protein that attaches to the cell membrane and tethers the protein as a peripheral membrane proteinD. any region on a protein’s surface that interacts with another molecule through noncovalent bonding
Answer: I think this is C
Explanation:
Plasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it can traverse cell membranes or diffuse.
The protein-binding site is any region on a protein’s surface that interacts with another molecule through noncovalent bonding. The correct option is D.
Why is protein-binding site important?A binding site is any region of a protein's surface that can interact with another molecule via noncovalent bonds. A protein can have binding sites for many different molecules, both large and small.
Protein binding is most clinically important in antimicrobial therapy, where a high degree of protein binding acts as a drug "depot,".
It allow for a longer duration of time the drug concentration remains above the bacterial minimum inhibitory concentration, thereby increasing antimicrobial efficacy.
Ligand binding sites are involved in a variety of protein biological processes, including signal transduction and enzymatic activity.
Understanding the properties of binding sites is critical in drug development and protein engineering.
Thus, the correct option is D.

What is a bad outcome of technology
Living things should not be viewed under a(n) _____ because the preparation process would kill them.
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.

Water moves out of the cell C. Water moves in and out equally D. Water does not move in the above situation. 11 Which of the following terms would best describe the effects on that cell? A. Apoptosis B. Crenation C. Lysis D. No effect of the cell
Answer:
A. Water moves into the cell
C. Lysis
Explanation:
Water moves into the cell due to high concentration of solutes i. e. sugar. If a cell has low concentration of solute than outside environment so the water moves outside toward more solutes while when the concentration of cell has more solute than external environment so water moves inside the cell towards more solute through the process of osmosis. Due to more diffusion of water into the cell, the Lysis will occurs in which the cell will burst due to expansion of its area.
