researchers combined sequences of fruit-fly dna from a gene for particular trait with frog dna .the mixture was heated to separate the dna strands .cooling allowed the single strands to for pairs. the researchers observed that some of the fruit-fly dna paired with frog dna .the results provided evidence that —
Answer:
The correct answer is - Similar nucleotides are present in both fruit-fly and frog DNA.
Explanation:
Fruit fly or drosophila DNA sequence and DNA sequence of the gene of frog for a particular trait is combined and heated to separate the DNA strands by separating the nucleotides present between the strands of both organisms.
This is observed after cooling down the single strands after paired up that some of the DNA paired with the DNA. This is only possible if the DNA strands of the particular gene have similar nucleotides to form hydrogen bond in single strands of DNA of frog and fruit-fly.
Diurnal animals are active
Answer:
During the day time
Explanation:
Diurnal animals are active during the day time and are inactive at night.
A wide range of animals fall into this category. Examples are human beings, chipmunks, goats, sheep etc.
As the sunrises, diurnal animals begins to get up and as the sun set, their activities reduces and they become inactive.
What happens to carbohydrates in fruit as they ripen? Make sure you explain the different carbohydrate molecules in the two stages of bananas and how that makes them taste.
Answer:
What happens to carbohydrates in fruit as they ripen is explained below in details.
Explanation:
As the fruit ripens after produce, the sucrose content develops only somewhat, while glucose and fructose progress in parallel, to enhance the principal sugars in ripe fruit. Carbohydrates are very essential in horticultural products because of their supplement to texture, flavoring, coloring, and nutritional value.
What does the "oxidative" in oxidative phosphorylation mean?
Oxygen is added to ADP to make ATP
Oxygen is necessary for the process which adds phosphorus to ADP
Oxygen phosphorylates ADP into ATP
Phosphorylating ADP into ATP releases oxygen as a bi-product
Answer:
B
Explanation:
Oxygen is the final acceptor of electrons in the process of oxidative phosphorylation. Without oxygen, the process becomes jammed with electrons.

Answer:
Abnormal BRCA1 and BRCA2 genes are found in 5% to 10% of all breast cancer cases in the United States. A study found that women with an abnormal BRCA1 gene had a worse prognosis than women with an abnormal BRCA2 gene 5 years after diagnosis.
Explanation:
If more airplanes and cars are used (both of which burn fuels) carbon levels will decrease ?
Answer: If the question is "would the carbon levels decrease?" then they would not, they would increase.
Explanation: More airplanes and cars would burn fossil fuels, and release more carbon dioxide, increasing carbon levels, not decreasing them.
What BEST describes the roles of photosystem I and photosystem Il in the process of photosynthesis?
Answer:
Photo system 1 = Light
This is the presence of sunlight, whereby Chlorophyll is used to trap sunlight energy to split water molecules into hydrogen ions and hydroxyl ions also NADP is reduced by the addition of hydrogen to form NADH
Photo system II: Dark stage
It happens when there is abscence of light where by CO2 ingested by plants react with hydrogen atoms from the light stage to form the Emperial Formula of simple sugar. Also Hydroxyl ions (OH -) is furtherly broken-down to oxygen & molecules.
Photosynthesis is the process in which green plant manufacturer their food in the presence of Sunlight ND chlorophyll. Where CO2 (Carbon [iv] oxide) and water (H2O)

What is the name of the winds that blow from the Poles southward?
Trade Winds
Westerlies
Sub-Arctic Northerlies
Polar Easterlies
Trade Winds is the name of the winds that blow from the Poles southward. So, the correct option is (A).
What are Winds?Wind is the movement of air caused by the uneven heating of the Earth by the Sun and the rotation of the Earth. This includes natural calamities/disasters ranging from light breeze to storms and tornadoes.
Sometimes winds arise from differences in atmospheric pressure. At the equator, the sun heats the water and land more than the rest of the world. Warm equatorial air rises up in the atmosphere and migrates towards the poles. This type of system is called a low pressure system while at the same time, cooler, denser air moves over Earth's surface toward the equator to replace the warmer air. This type of system is called a high pressure system.
The boundary between these two areas is called a front and the complex relationships between fronts cause different types of wind and weather patterns. The Earth contains five major wind zones:

define kinetic energy and thermal energy. Describe what happens to each as the temperature of a substances increases.
Explanation:
All matter is made up of particles that are constantly moving. The motion of the particles results in kinetic energy. The part of total internal energy that can be transferred is thermal energy. As temperature increases, the particles in a substance move faster and have greater kinetic and thermal energy.

What were the first vertebrates to evolve?
The earliest vertebrates that use to resembled are hagfish and lived more than 500 million years ago. As other classes of fish appeared, they evolved traits such as a complete vertebral column, jaws, and a bony endoskeleton.
What are Amphibians?Amphibians were the first tetrapod vertebrates as well as the first vertebrates to live on land. Segmentation is a part of characteristic of the body plans of various goup of animals including the annelids, and recently developed vertebrates. There are three different segmental systems origin in development of the vertebrates that are - the somites, the rhombomeres and the pharyngeal arches.
There are several benefits of the segmentation development and these are the different type of anatomical and morphological developments are helps in facilitate specific functions are led by the segmented body.
The Paraxial mesoderm also have segmentation that helps in lateral movement and It has been also helps in the consistent and fast interaction or communication in the neuronal system.
