When heat leaves your body, how far could it travel?
Answer:
over 6 ft
Explanation:
Answer:
over 6 feet probably about 10 to 15 ft to be exact.
Explanation:
That is because your heat slowly devolves into chemicals that trees use for oxygen. And if there is no trees around it can take 100's of miles until it gets to trees.
Thomas and Julie wanted to find out which material would insulate their
teacher's coffee cup and keep the coffee hot for the longest period of
time. They first wrapped her cup with bubble wrap and recorded the
temperature of the coffee once every 15 minutes for 2 hours. They
repeated the investigation, this time using newspaper instead of bubble
wrap, but they got the same results for both materials. Which of the below
is their control or constant variable?
the type of insulation
the temperature of the coffee
the type of coffee cup
The students conducting the experiment
Answer:
The type of coffee cup
Explanation:
Because the insulation changed
The type of coffee temperature can change
The students can change
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.
What is a dihybrid cross?A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.
Given,
Autosomal dominant = Bb (beard), W (black coat)
Autosomal recessive = B+ (beardless ), w (white coat)
Parent = B+Bb Ww male and B+Bb Ww female
The cross between the parent is attached to the image below.
From the cross, it can be said that:
9/16 bearded, black coat1/16 beardless, white coat3/16 beardless, black coat3/16 bearded, white coatFrom the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.
Therefore, options b and e. 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.

Ok y’all I don’t have time to research for my sis so I will ask a bunch of questions
Answer:
stomach
Explanation:
During digestion, muscles push food from the upper part of your stomach to the lower part. This is where the real action begins. This is where digestive juices and enzymes break down the food that you chewed and swallowed.
Answer:
mouth
Explanation:
The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
When are acids used in the human body?
Answer:
The most commonly-known way is in the stomach, during digestion.
Jaden's father is not sensitive to poison ivy. Jaden is also not sensitive to poison ivy. Jaden's lack of sensitivity to
poison ivy is which kind of trait?
environmental
acquired
learned
inherited
Answer:
Jaden's lack of sensitivity to poison ivy may be an inherited trait.
Explanation:
The poison ivy poisoning is due to the essential oils of this plant, mainly uroshiol, causing a reaction in the skin characterized by intense itching, redness and even burns with flicthenes, manifesting as an allergic reaction of varying severity.
Some people may have a low sensitivity or be insensitive to uroshiol, which does not rule out the possibility that they may become sensitive at some point in their lives.
The fact that Jaden and her father are insensitive to poison ivy venom may be an inherited trait, determined by a resistance to the allergic reaction the plant produces.
Regarding other options:
Environmental, acquired or learned traits, do not determine the resistance to certain hypersensitivity or allergy reactions, which depends on each person's immune response or sensitivity.
Answer:
inherited

Shark
PLEASE HELP ASAP
Answer:
=) salmon
Explanation:
The primary cause of these orcas deaths is starvation. The southern residents—which include the J, K, and L-pods—survive mainly on Chinook salmon, another species in decline due to overfishing, hydroelectric projects, and the harbor seals that get to them before they make their way to Puget Sound

Using established recombinant DNA technology, you insert a gene from a human liver cell into a bacterium. The bacterium then expresses a protein corresponding to the inserted DNA. To your dismay, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by the eukaryotic cell.
Assuming there is no mutation in the human gene, explain why this happened.
a. bacteria do not use splicing to edit RNA after its transcription.
b. rRNAs in bacterial cells contain more nucleotides than in eukaryotic cells.
c. bacterial RNA contains less stop codons.
d. amino acids in bacterial cells are specified by double codes.
Answer:
The fact that the amino acid chain is consistently having more amino acids than what is actually present can be attested to the fact of how gene expressions can be observed in the prokaryotic cell compared to the eukaryotic one.

Without heat from the Sun, the water cycle would...
A)
reverse
B)
not work
slow down
D)
not be affected
Answer:
B; Not work
Explanation:
Water constantly moves around the Earth and changes between solid, liquid, and gas. This all depends on the Sun's energy. Without the Sun there would be no water cycle, which means no clouds, no rain, no weather.
Some of the water that falls as rain evaporates back into the atmosphere. What happens to the water molecules during this process?
Answer:
The water molecules separate into oxygen and hydrogen molecules which allows them to transfer back up into the atmosphere in their individual state.
