The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.

Only laboratories BSL-3 and higher require fire extinguishers, emergency showers and eye wash stations.
Answer:
false
Explanation:
Fire extinguishers, emergency showers and eye wash stations are basic safety elements that must be present in all laboratories, regardless of their classification. This is because these are essential elements for common accidents in laboratories and can be easily solved with their presence.
Explain how diffusion is used to support the life processes of animals.
Answer:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow.
Explanation:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
The dandelion is a successful weed. Explain why its adaptations make it a better competitor than many other plants on a school field or a garden lawn.
Answer:
The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.
Explanation:
The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.
Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind. Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.
Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution?
Answer:c
Explanation:
c
Embryology is used in evolution because similar structures often also exhibit a common evolutionary origin.
Embryology refers to the discipline that studies the early development of an organism.Evolution is a biological process associated with descendence with modification, thereby evolutionary close organisms share similar features.Embryology often evidences evolutionary relationships due to the resemblance between structures found in different organisms.In conclusion, embryology is used in evolution because similar structures often also exhibit a common evolutionary origin.

A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.
Hope this helps (:

What are three kinds of volcanoes? What makes them different?
Answer:
Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.
Composite volcanoes are tall, steep cones that produce explosive eruptions.
Shield volcanoes form very large, gently sloped mounds from effusive eruptions.
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

4. Why does semen contain fructose?
A. Fructose breaks down to provide energy for the penis.
B. Fructose travels with the sperm to feed the egg before it is fertilized.
C. Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
D. Fructose provides energy for the development of the fertilized egg.
I’ll give brainiest:)
Answer:
The answer is C
Explanation:
I just got it right on the quiz
Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.
What is fructose?Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.
The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

The hours of daylight can vary greatly because of latitude. How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.
Answer:
Explanation:
The amount of daylight that is received is directly proportional to how close the sun is to each hemisphere. This happens due to Earth's inclined axis which changes as the Earth rotates and causes more daylight in the Northern or Southern hemispheres which is when summer starts in each. That being said the Equator is the only location that has an even amount of sunshine all year round. This is why it is always hot and Equator cultures only recognize dry and wet seasons but still consider it summer all year round.
For a certain plant, purple flowers (allele: P) are dominant and white flowers (allele: p) are recessive. A heterozygous purple plant is crossed with a true-breeding (purebred) white plant. What are the possible genotypes (allele pairs) of the offspring?
The possible genotype of all the offspring will be PP, and Pp as per the given situation.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.
The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.
The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.
Thus, the possible genotype will be 50% PP and 50% Pp.

This soil sample is the LEAST porous?
True or false
Answer:
False
Explanation:
Soil with least porosity
Thus, the correct answer is 'Clay soil. '
There are other types of soil that can be more crumbly, but this is not the least. Because porous means something is full of tiny holes or openings, you can see that this is the right word to match it with! The least crumbly, or porous would only have a little crack. Good luck, and I hope this helped!
Also....
Clayey soil is the least porous.
Clayey soil is the least porous soil as the spaces between the molecules of the soil is less and water cannot pass through them.
