DNA is made up of molecules called nucleotides. ... Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs

In order to dilute a solution, you need to
A-add more of the solid
B-add more water
C-find the mass
D-find the volume
What would be an appropriate key for these traits
Answer:
The correct answer is -
TT - short BB - blue eyes
Tt - short tail Bb - blue eyes
tt - no tail bb - brown eyes
Explanation:
In this given question it is stated that short tails of ribbits are dominant over the no tail trait of the rabbits and similarly blue eyes trait of the rabbits is also dominant over the brown-eye trait.
A dominant trait is represented by a capital letter and a recessive trait is represented by the small letter so for the tails alleles will be denoted as T and t, and for the eyes, the alleles would be B for blue and b for brown.
The key for these traits would be-
TT - short BB - blue eyes, due to both dominant allele,
Tt - short tail Bb - blue eyes, due to dominant allele masks the recessive allele
tt - no tail bb - brown eyes, due to both alleles are recessive

What is cell division ?
In a living organism there are two types of cell such as somatic cell and germinal cell which undergo the process of cell division.
Cell division occur which can be up two types such as mitosis and meiosis where mitosis is called as equatorial cell division as the number of daughter cell is equal to number of parent cell.
meiosis is called as reductional division as the number of daughter cell is half of the parent cell, occur in germ cell.

What controls the timing of The Great Migration?
Answer:
The best time to see the Great Migration is during the dry season, between July and early October. It's warm, weather is stable, and animals are abundant. The sparse vegetation and dried-up waterways force the animals to head up north to find food and drink.

How are the vocabulary terms diploid and haploid related to each other?
Answer:
Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

Frida wants to measure the volume of a stone. The correct volume is B
The volume of the stone is 26 mL.
What is volume?
The initial volume = 473 mL
The final volume = 499 mL.
The final volume − Initial volume
= 499 − 473
= 26 mL.
Therefore, Frida wants to measure the volume of a stone. The correct volume is B .The volume of the stone is 26 mL.

Listed in blue, please help!! Is biology and chemistry two different things and why?
Answer:
Yes they are two different things!
Explanation:
Chemistry is more basic to existence-it is the study of the composition of matter and all associated structures, properties, and reactions. This includes, but is not limited to, biological matter. Biology meanwhile is focused entirely on biological organisms.
Answer: Yes they are
Explanation: Biology is the study of life and the ecosystems of what surrounds it. Biology consists of anatomy marine biology and the spheres of the earth. Chemistry has to do with our elements take gold for example it is known as Au or Aurum. Element 79 with an atomic mass of 196.96657u you will learn this in chemistry. Chemistry makes biology like a scratch on the surface because in chemistry you are going deep into the elements by classifications and the periodic table. You will be able to learn about dissolvents and why salt dissolves in water. You will learn about molecules in both fields. In general, biology is more the basis of life and chemistry is the more complexity of life.
Help please describe how the biotic factors taiga differ from those in the rainforest
Answer: biotic factors include plants and animals. So, the rainforest animals are more adapted to warmer weather meaning they have less fur and are built for warmer weather. The plants in a rainforest need lots of water to survive as well as carbon dioxide so they have large, wide leaves.
In a Taiga biome, the animals have more fur and adaptations to help them to survive in colder weather. The plants primarily consist of fir and pine trees, which have waxy, needle-like leaves to retain water as well. The trees also dont lose their leaves in the winter.
Explanation:
The biotic factors are significantly found to be different in two types of habitation such as taiga and rainforests.
What are biotic factors?Biotic factors may be defined as those factors that are directly associated with living forms. It includes producers, consumers (herbivores, carnivores, and omnivores), decomposers, etc. It may also be characterized as any living thing that has a significant effect on an ecosystem.
The animals in the rainforests adapted to the average temperature that remains warm throughout the year and must be frost-free. So, the animals generally have less fur. While the plants require more water in order to survive and reproduce at a higher temperature.
The climatic conditions on taiga are actually cold as compared to the rainforests. So, the animals possess fur appearance in order to survive in low temperatures. The plants compose of waxy structures and needle-like leaves in order to retain water. The number of leaves remains the same throughout the year.
Therefore, the biotic factors are significantly found to be different in two types of habitation such as taiga and rainforests.

FACURE IS 1CM ON A SIDE, CALCULATE ITS VOLUME. HINT WRITE OUT
Answer:
Surface area of the cube = 6cm²
Volume of the cube = 1cm³
Explanation:
The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:
S.A = 6 × a²
That is; a² + a² + a² + a² + a² + a²
Where;
a = length of a side of a cube
a² = area of one side of a cube
Note that, a cube has 6 faces
According to this question, a cube has a length of 1cm on each side.
Hence, S.A = 6 × 1²
S.A = 6 × 1
S.A = 6cm²
Volume of the cube can be calculated using the formula: a³
Where a = 1
Volume = 1 × 1 × 1
Volume = 1cm³

Why would scientists want to monitor the migration habits of red-winged blackbirds in MA?
Answer:
Blackbird and Oriole : Varieties of swamps, shrubs, swamps, and dry grasses; foraging in arable land and water. The species is most commonly found in freshwater marshes, but in wooded or bushy marshes, weed fields, hay fields, and salt marshes also have levels on the upper edge. Usually foraging in other open habitats, such as fields and tidal flats; outside the breeding season, flocks of chickens gather in farmlands, pastures and feedlots.
Among the birds we are most familiar with, the red wings seem to sing nasal sounds on every swamp and wetland from coast to coast. They are particularly bold, and a few often attack larger birds, such as eagles or crows, and they fly over their nesting areas. When singing, the male's red shoulder patches are hidden under the body feathers most of the time, which is very beautiful. Outside the nesting season, red wings sometimes live in large areas.
