Answer:
-10
Explanation:
add all temperatures together divide by 5 for your average
Answer:
-10°F
Explanation:
We want to find the average low temperature for the five days. To find an average, add up every value, then divide by the number of values.
The data given is:
-8°F, -13°F, -4°F, -9°F, -16°F
1. Add the values
-8 + -13 + -4 + -9 + -16
-50
2. Divide by the number of values
Count how many numbers there are. The data was for 5 days, so there are 5 values.
-50/5
-10
The average low temperature for the 5 days was -10 degrees Fahrenheit.

A:group
B: Period
They have the same number of____
A:Valence electrons
B:Electrons shells
Answer:
Sodium, Magnesium, and Sulfer are all in the same period meaning they have the same number of electron shells.
Explanation:
Periods are rows in the periodic table. The number of Valence electrons grows across the period (left to right) until reaching the electron shell's capacity.
Groups occur in columns in the periodic table and all have the same number of valence electrons, and the number of electron shells increase as you move downward on the table

7. Mrs. Everhart developed the theory that all bulldogs are great pets. After all her bulldog Meatball is a
wonderful dog! Is this statement a scientific theory? Why or why not.
finoccientific method
Answer:
No it is not a scientific theory.
Explanation:
An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.
Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.
For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.

The stage of the stress response in which the pituitary gland releases a flood of adrenocorticotropic hormones is
Answer:
This is Alarm.
Explanation:
Adrenocorticotropic hormones and stress.
This the hormones secreted at the corticotrophs cells of the anterior pituitary glands.Its major function is to ensure the efficient functioning of the Adrenal gland and body response to stress.It is also mediate the secretion of cortisol from the cortex of the adrenal gland into the blood stream.When it is released into the blood streams it binds to the receptors in the adrenal gland to stimulate the release of cortisol hormone.
ACTH controls diurnal (circadian) rhythm in human.This is because it peaks in the morning and progressively reduced towards the end of the day,with lowest concentration during period of sleeping.
Generally stress either by dehydration or internal complications,leads to increase in solute potential of the blood.Stress increases the activation of ACTH from the adrenal gland while boosting the concentration of cortisol. When the stress is sensed by the brain,this causes the release of corticotrophin-releasing hormone into the bllood.
The latter cause the discharge into the blood stream of ACTH via hypothalamic–pituitary–adrenal (HPA) axis.As this enters the blood it binds to the receptors for the cortisol secretions in the cortex of the adrenal gland to produce cortisol as explained earlier.Cortisol is the primary sex hormone which create the alarm.

TOR kinases are enzymatic proteins found in a diversity of species, from yeasts to mammals. They serve in a phosphorylation cascade that promotes progression through the cell cycle. What evidence would confirm that eukaryotes share a common ancestor with regards to cell signaling pathways?
Answer:
By phylogenetic analyses
Explanation:
The target of rapamycin (TOR) is a major regulator of growth only found in eukaryotic organisms. The TOR pathway is known to regulate critical cellular processes including, among others, cell growth. The TOR protein is a kinase capable of activating translation by phosphorylation of the ribosomal S6 kinase (S6K) and the eukaryotic translation initiation factor 4E binding protein (4E-BP). In this regard, phylogenetic studies have shown that this pathway involves duplication events of ancestral kinases, as well as sub-functionalization of the S6K kinase.

Which of these would be a disadvantage when forming a fossil? hard body parts buried quickly high oxygen atmosphere high pressure
Answer:
c
Explanation:
usatestprep
The disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option, as the high oxygen atmosphere can lead to the rapid decay of organic matter, making it less likely to be preserved.
What is a fossil?Because oxygen is a reactive gas that can decompose organic material when exposed to high temperatures and pressures, fossils will be destroyed in such a climate, which is why fossils are more commonly found in environments with low oxygen levels, such as deep underwater sediments or anaerobic environments like swamps and bogs. One of the main factors that determines whether or not an organism will be fossilized is the speed at which it is buried after death, if an organism is buried quickly, it is less likely to be disturbed or exposed to scavengers.
Hence, the disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option.
