In fruit Flies a white eyed female is crossed with a red eyed male. What are the changes the offspring will be a white eyed male?
Answer:
the chances of the offspring having white eyes is 50%
Explanation:
i used a punnet square to calculate the output:)
Answer:
25%
Explanation:
There's a 50% chance of the offspring being male & 50% chance female. The genotypes must be co-dominant otherwise their question doesn't give enough information to get an anwser. Also a 50/50 chance of red/white, so added together a 25% chance.
Also, the funny thing is that remember this from 7th grade so you must be reviewing things that evreyone learned a long time ago but forgot.

You make two agar plates: one is a nutrient agar plate (plate A) that contains histidine and penicillin. The other is a glucose salts agar (plate B) that also contains penicillin. You inoculate a sample onto both plates using replica plating technique, incubate the plates, and compare the growth after 48 hours. There are 12 colonies on the nutrient agar plate and 11 colonies on the glucose salts medium. Which of the following statements is INCORRECT?
a. The colony that is missing from plate B is an auxotroph that cannot synthesize histidine.
b. The prototrophs are resistant to penicillin but the auxotrophs are sensitive to this antibiotic.
c. Prototrophs and auxotrophs in this experimeſit are resistant to penicillin.
d. Approximately 92% of the bacteria in the original sample are prototrophs.

How does sexual reproduction bring about variation
Answer:
The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.

6. What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods (or in a heat wave with no air conditioning)
Answer:
Shivering and sweating.
Explanation:
A prolonged exposure to extreme cold environment would activate the brain's heat-gain center. Your brain's heat-gain center causes shivering in order to increase our muscle contraction which leads to warming of our body. Increase sweating is the regulatory processes our body use if it experience very high temperature. In order to regulate internal temperature of body, our body remove water which takes up heat with itself to lower th internal temperature.
The table above shows the nutritional information in a bottle of pop. Drinking 16 oz of this beverage would provide which of the following?
A.

C.
15% of the total carbohydrates for a person on a 1,000 diet
D.
30% of the total carbohydrates for a person on a 2,000 calorie diet
Answer:
30% of the total carbohydrates for a person on a 2,000 calorie diet
Explanation:
Study Island
30% of the total carbohydrates for a person on a 2,000 calorie diet will provide if drinking 16 oz of this beverage.
How is 30% 15% in the given table?The table is based on 2000 calories, and one serving is 8 oz.
Thus the question is for two servings.
Which equals 30% carb of a 2k calorie diet.
What are carbohydrates?Carbohydrates are macronutrients that provide energy to our bodies in three ways.Carbohydrate-containing foods are converted into glucose or blood sugar by the digestive system during the digestion process.Thus, we can conclude that option D is the correct option, 30% of the total carbohydrates for a person on a 2,000 calorie diet.

“Scientist have long understood how nutrients move from the oceans surface to its depths. As phytoplankton die, they sink and collect on the ocean floor. But if nutrients are continually sinking to the depths of the ocean, how are surface waters replenished with nutrients? Scientist discovered that in certain regions of the ocean, the nutrients-rich deep water was upwelling, or rising to the surface”
which phrase from the paragraph helps you to understand that ocean health involves steady restoration
Answer:
"As phytoplankton die,they sink and collect on the ocean floor"......."scientist discover that in certain regions of the ocean the nutrients deep water was rising to the surface"
Explanation:
this shows steady restoration of ocean nutrients
As seen that the death of planktons lead to uprise in oceanic nutrients .the cycle just keeps going on and on
its quite self explanatory
A PCR-RFLP analysis was performed to identify PTC tasters in a population. The taster allele sequence included a palindromic sequence recognized by a restriction enzyme, whereas the non-taster allele did not due to a SNP in the sequence.

Is it a good idea for humans colonize mars pls real answers :)
Answer:
I believe yes and no at the same time
Explanation:
If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?
Answer:
Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors
But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains
In conclusion, no it would not be a good idea.
what is evolution?...
Answer:
Evolution is an adjustment of the heritable attributes of natural populaces over progressive ages. These attributes are the outflows of qualities that are given from parent to posterity during generation. There are also three main types of evolution: divergent, convergent, and parallel evolution.

If you pressed a stethoscope diaphragm firmly on a volunteer's skin at the following locations on the right side of the body: Inferior to the clavicle (this is the 1st intercostal space) In a more inferior intercostal space Along the medial border of the scapula What type of sounds are you listening for
Answer:
The correct answer is - Vesicular Breath Sound.
Explanation:
The vesicular breathing is lower-pitched and soft where expiration is shorter than inspiration and there is no pause between expiration and inspiration. It can be heard through the thorax and with a stethoscope around the lungs or the thorax inferior to the clavicle, medial border of the scapula, and intercostal space. It can be heard with each expiration around the lung area.
Thus, The correct answer is - Vesicular Breath Sound.

What is tRNA?A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.
Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.
Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.
Therefore, The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.
