According to the base-pairing rules of DNA, if the sequence of bases on one strand was CGGCTTA, what would be the sequence of based on the complementary strand?
Answer:
GCCGAAT
Explanation:
Deoxyribonucleic acid, also known as DNA, is a molecule that serves as the genetic material in living organisms. It is a double-stranded molecule made up of nucleotides subunits. The nucleotides, which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T) on each strand are held together using the COMPLEMENTARY BASE PAIRING RULE.
The complementary base pairing rule states that an Adenine base will always hydrogen bond with Thymine base while Guanine will always bond with Cytosine base i.e. A-T, G-C. Based on the rule, a DNA strand with sequence: CGGCTTA will have a complementary sequence of GCCGAAT on the other strand.

Which statement best explains why an object appears green in sunlight?
The object absorbs most white light and refracts most green light.
The object refracts most white light and absorbs most green light.
The more green light is absorbed while more red and blue light are reflected.
More green light is reflected while more red and blue light is absorbed
Answer:
More green light is reflected while more red and blue light is absorbed. is D
Explanation:
An object appears green in sunlight because it reflects more green light and absorbs more red and blue light. So the correct option is D.
Why do we see colours?The overall perception of colours depends on the length of the energy wavelengths. Red colour has the longest energy wavelength and violet colour has the shortest energy wavelength.
When sunlight hits an object, a material will absorb a specific wavelength. Sunlight is a combination of all wavelengths. The wavelengths that are not absorbed by an object are reflected.
The reflected light reaches our eyes and is perceived. Thus, the colour that we associate with an object depends on what wavelength is reflected.
When the sunlight reaches our eyes, the rods and cones of the retina are stimulated. This stimulation signals the brain of our colour perception. The rods and cones have specific colours and lighting by which they are activated.
Therefore, an object will appear green because it absorbed red and blue light and reflects green light. The correct option is D.

Which of the following correctly characterizes one of Earth's atmospheric layers?
A
Layer A is the stratosphere, where meteors are found.
B
Layer B is the troposphere, where weather occurs.
с
Layer C is the stratosphere, where the ozone layer is found.
D
Layer D is the thermosphere, where auroras are found.
Answer:
it is A layer A is the stratosphere where meteors are found
Explanation:
Answer:
It is Layer D
Explanation:
It would not be a because the first layer is not stratosphere but troposphere. It would not be b because layer b should be the stratosphere. It would not be c because layer c should be mesosphere not stratosphere. Which leads us to the only answer choice that is left answer choice D.
Place the four images from the cell cycle in the correct chronological order.
A, D, B, C
C, D, B, A
C, B, A, D
B, C, D, A
Answer:
C, B, A, D
Explanation:
The images in this question is portraying the stages involved in MITOSIS, which is a kind of cell division that forms two genetically identical daughter cells. The four stages of mitosis represented in the image are as follows: interphase, prophase, metaphase, and anaphase
- INTERPHASE: This stage is regarded as the resting stage of the cell. The chromosomes are found to be supercooled together as chromatins as seen in image C.
- PROPHASE: In the prophase stage, the chromosomes become condensed and more visible as seen in image B.
- METAPHASE: In the metaphase stage, the chromosomes align at the equator of the cell in order to be pulled apart by microtubules as seen in image A.
- ANAPHASE: In the Anaphase stage, the chromosomes are pulled apart into opposite poles of the cell as depicted in image D.
The images of the cell cycle in the correct chronological order would be C, B, A, D.
The order of the cell cycle is from the interphase to the m phase.
The interphase order is:
G1 phase - cell growth and developmentS phase - DNA synthesisG2 - protein synthesisThe m phase order is:
Prophase - nuclear envelope dissolves, chromatin condensesMetaphase - chromosomes align at the equatorAnaphase - sister chromatids are pulled apart and migrate to opposite polesTelophase -migration of sister chromatids completeIn the image:
A - metaphaseB - S phase C - G1 phaseD - telophaseHence, the order would be C, B, A, and D.

Scientists studying the Delta water notice that levels of both chlorophyll and sediment in the water rise and fall on a regular cycle. Which of these hypotheses are consistent with their data? Select all that apply.
A.
Phytoplankton populations increase during warmer, summer months.
B.
Phytoplankton populations decrease as chlorophyll in the water increases.
C.
Sediment deposition in the Delta increases when snow melts during the summer.
D.
Phytoplankton populations increase after sediment is washed into the Delta.
E.
Sediment flow is impeded by the growth of plants and animals in the water.
Answer:
i think B can you help me plz
Explanation:
In water chlorophyll and sediment rise and fall when chlorophyll level and light increase it will increase the phytoplankton population when sediment is washed into the delta, hence option b is correct.
What is phytoplankton?Phytoplankton, which includes single-celled algae and other creatures that resemble plants, makes up the base of the ocean's food chain.
Chlorophyll and other light-harvesting pigments are used by phytoplankton, just like plants on land, to perform photosynthesis, absorbing atmospheric carbon dioxide to create sugars for fuel.
The stratification, or layering, intensifies with increasing surface water temperature and further inhibits mixing. As a result, phytoplankton productivity and nutrient transport from deeper water to surface waters both decrease.
Therefore phytoplankton population is affected by the chlorophyll and sediments to increase photosynthesis, hence option b is correct.

8. Which of the following are functions of external regulators of the cell cycle?
Select two answers.
a. regulate checkpoints
b. make sure chromosomes have replicated
c. speed up or slow down the cell cycle
d. stop the cell cycle
Speed up or slow down the cell cycle are functions of external regulators of the cell cycle.
The regulation of cell proliferation, growth and DNA synthesis are controlled by the regulatory machinery of the cell cycle.
Cell cycle progression is activated directly by a series of heterodimers formed by cyclins and cyclin-dependent kinases (CDKs).
Cyclin D, by forming a complex with the cyclin-dependent kinases CDK4, activates the action of the kinase whose main substrate is the Rb protein. Cyclin D are proteins that respond to external signals in cells and execute responses such as acceleration of the cell cycle.Cyclin D1 is a protein encoded by the CCND1 gene this acts on the cell cycle by accelerating the G1 phase.In the hypophosphorylated state, the Rb tumor suppressor protein is active and performs its function by inhibiting cell cycle progression.Therefore, we can conclude that speed up or slow down the cell cycle are functions of external regulators of the cell cycle.
