Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.
A technique that can be used to separate proteins based primarily on the presence of non-polar residues on their surface is called A) ion-exchange chromatography. B) gel filtration chromatography. C) affinity chromatography. D) gel electrophoresis. E) hydrophobic interaction chromatography.
Answer:
E) hydrophobic interaction chromatography.
Explanation:
Hydrophobic interaction chromatography (HIC) is a methodology used to separate protein molecules depending on their hydrophobicity. HIC enables the separation and purification of proteins by using a reversible interaction between the target protein and the hydrophobic ligand of a HIC resin such as, for example, methacrylate-based beads. This interaction is influenced by the running buffer (high salt concentrations favor hydrophobic interactions). HIC enables the separation of proteins under low denaturation conditions, thereby preserving their biological functions.

HOPE IT HELPS YOU.Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

differences between regolith and bedrock in 5 points
Answer:
Explanation:
Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. ... Bedrock also underlies sand and other sediments on the ocean floor. Bedrock is consolidated rock, meaning it is solid and tightly bound. Overlying material is often unconsolidated rock, which is made up of loose particles.
Regolith is a blanket of unconsolidated, loose, heterogeneous superficial deposits covering solid rock.

Malcolm altered an experiment to be able to reach his desired conclusionResponsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.
Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.

Answer:
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains.
Explanation:
took the test and got it correct
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. The correct option is D.
What are Eubacteria?Eubacteria are bacterial counterparts. They go under the name "real bacteria." They lack membrane-bound cell organelles and a genuine nucleus. These are single-celled, tiny creatures.
Contrary to appearances, Eubacteria and Archaebacteria (also known as Archaea) are divided into distinct realms of life based on variations in their genetic make-up, particularly in the sequences of their ribosomal RNA (rRNA).
Together with Eukarya, Eubacteria and Archaebacteria are currently acknowledged as distinct domains of life.
This classification represents the underlying biological differences between the two categories, including variations in cell walls, lipid membranes, and metabolic pathways.
Thus, the correct option is D.

what is role of the stomach in the human digestion system
Explanation:
The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are processed enough, they’re released into the small intestine.
Answer:
first the stomach secretes the gastric juice which is made up of digestive enzymes and digest the hydrochloric acid and plays a big role in digesting nutrients.

How high is the ceiling in a school gym if a volleyball thrown upward from the floor at 15 m/s barely touches the ceiling before returning to the ground?
Answer:
11.47 m
Explanation:
Givens
vi = 15 m/s
a = - 9.81 m/s^2
vf = 0
d = ?
Formula
vf^2 = vi^2 + 2ad
Solution
0 = (15)^2 + 2*(-9.81)*d
- 225 = 2 * - 9.81 *d
-225 = - 19.62 * d
d = - 225/-19.62
d = 11.47 m
The height of the ceiling in the school gym from the floor is 11.48m.
HOW TO CALCULATE HEIGHT OF A PROJECTILE:
Using one of the equations of motion as follows:v² = u² + 2as
Where;
v = final velocity (m/s)
u = initial velocity (m/s)
a = gravitational acceleration (m/s²)
s = distance traveled (m)
According to this question,
The final velocity (v) of the volleyball is 15m/sThe initial velocity is 0m/sThe acceleration due to gravity is 9.8m/sUsing the formula, v² = u² + 2as, the height of the ceiling (s) can be calculated as follows:
15² = 0² + 2 (9.8) (s)
225 = 0 + 19.6s
225 = 19.6s
s = 225/19.6
s = 11.48m
Therefore, the height of the ceiling in the school gym from the floor is 11.48m

At temperatures higher than the maximum growth temperature for an organism:
a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.

Consider the following chromosomes and if they are affected by hemophilia.
X = unaffected X chromosome, x = X chromosome affected by hemophilia, and Y = Y chromosome.
If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by hemophilia?
(1 point)
A. 1/4 and 1/2
B. 1/2 and 1/4
C. 1/2 and 1/3
D. 1/4 and 1/4
I've been stuck on this question for a while, may someone please assist?
Answer:
B. 1/2 and 1/4
Explanation:
Hemophilia is a rare disease that has to do with the inability for blood to clot. It is inherited on the X chromosome, hence, it is said to be X-linked. It is usually passed from mother to son. According to this question;
X - unaffected X chromosome
x = X chromosome affected by hemophilia
Y = Y chromosome
Therefore, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:
Xx- X and x gametes
XY- X and Y gametes
Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY will be possibly produced.
XX (1) - unaffected female
Xx (1) - unaffected but carrier female
XY (1) - unaffected male
xY (1) - affected male (have hemophilia)
Based on the questions;
- 2 out of the possible 4 children will have the affected chromosomes i.e. both xY son and Xx daughter have the affected (x) chromosome. Hence, the fraction is 1/2
- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.
