Why are the supraorbital height and thumb indexes important measurements in
comparing primates
The supraorbital height is an important measurement in comparing primates because they give information related to the size of the skull above the eyes.
What do you mean by Primates?Primates may be defined as those organisms which generally have flexible hands and feet with opposite first digits, good eyesight, and, in the higher apes, a highly developed brain.
As primates have an internal system, it is required to measure their skull size, thumb length, etc. So, the above techniques are used for measurement and comparison.

Anna runs 5 km in 20 minutes. What is her speed in kilometers per hour?
Answer:
15 km/h
Explanation:
5 km in 20 min
5km is 5000m and 20 min is 20×60 =1200s
5000÷1200= 25÷6 m/s
To convert m/s to km/h we multiple by 18/5
25÷6×18÷5
15 km/h.

Answer:
Mar 29, 2007 · Child Artists' Tools Include Mixed Media, Maggots Letting kids dip maggots into paint may sound merely disgusting — but there's an entomologist from U.C.-Davis who calls it …
Explanation:
By making "maggot art," Ms. O'Flaherty is utilizing maggots in a distinctive way.
What is Maggots art?A great approach to get kids interested in insects, especially fly larvae, is through maggot art. Although it is mostly geared towards kids between the ages of 6 and 14, parents and siblings of all ages find it entertaining as well! Prepupillary blow fly larvae are submerged in non-toxic solution as the main assumption.
Fly eggs are laid everywhere there is a protected area and a fresh food source again for new brood of maggots to feed on. Maggots hatch from these fly eggs. As a forensic entomologist, Ms. O'Flaherty frequently employs maggots to, among other things, ascertain the time of death through investigation and examination. Three main positive benefits of maggots on wounds include debridement, disinfection, and improvement of wound healing.
Thus, by making "maggot art," Ms. O'Flaherty is utilizing maggots in a distinctive way.

Blood glucose begin to increase after a meal. As a result, glucagon levels must _________ while insulin levels must ________ in order to maintain metabolic homeostasis.
If glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.
What is homeostasis?Homeostasis is the process by which a stable internal environment is maintained irrespective of the changes in external conditions.
The regulation of sugar level in the blood is one of the homeostatic responses. Insulin and glucagon are two hormones used to perform this task of blood sugar regulation.
Insulin is an hormone that reduces blood sugar level by stimulating the conversion of excess sugar to glycogen.Glucagon, on the other hand, increases blood sugar by converting glycogen back to sugar.Therefore, if glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.

Our oceans absorb carbon dioxide from the air. Carbon doxide and ocean water form carbonic acid.
This causes the ocean's pH to become 4b
O lower
O higher
O it does not change
lower since it is becoming more acidic
The absorption of carbon dioxide from the air by the oceans causes the ocean's pH to become lower, meaning it becomes more acidic. Therefore option (A) is correct.
What affects ocean's pH?The ocean's pH can be affected by a variety of natural and human factors. One of the primary factors affecting the ocean's pH is the absorption of carbon dioxide from the atmosphere. As carbon dioxide dissolves in seawater, it reacts with water to form carbonic acid, which increases the concentration of hydrogen ions (H+) in the water and lowers the pH.
Other factors that can affect the ocean's pH include volcanic activity, which can release large amounts of carbon dioxide and other chemicals into the ocean, and nutrient runoff from land, which can lead to algal blooms that increase carbon dioxide and lower the pH. Human activities, such as burning fossil fuels and deforestation, can also release large amounts of carbon dioxide into the atmosphere, contributing to ocean acidification.

They are not stable atoms.
They are not readily available on Earth.
They tend to give up all of their valence electons easily.
They have the maximum possible number of electrons in their outermost shell.
Answer:
They have the maximum possible number of electrons in their outermost shell.
Explanation:
There are only a few elements that are less reactive than noble gases. The reason for this is that they are filled with electrons, which are referred to as valence electrons.
Essentially, the more electrons on the outermost shells, the less reactive.

What material is too important to ever leave the nucleus? A. DNA B. Protein. C. Ribosomes D. Chromosomes
A. DNA is too important to ever leave the nucleus.
DNA material is too important to ever leave the nucleus. Hence the correct option is A.
DNA (Deoxyribonucleic Acid) is a crucial molecule found within the nucleus of cells. It carries genetic information and instructions necessary for the growth, development, functioning, and reproduction of living organisms. The information encoded in DNA determines an organism's traits, characteristics, and overall biological processes.
DNA's essential role in inheritance and cellular activities makes it too important to ever leave the nucleus. While other cellular components like proteins, ribosomes, and chromosomes are important, DNA is the primary genetic material that must remain securely stored within the nucleus.
Hence the correct option is A.
