Answer:
red blood cells
Explanation:
Answer:
Blood cells formed in the bone marrow start out as stem cells. A stem cell (or hematopoietic stem cell) is the first phase of all blood cells. As the stem cell matures, several distinct cells evolve. These include red blood cells, white blood cells, and platelets.

How do adaptations affect organisms such as orchid plants
Answer:
Orchids are very well-adapted to life in the canopy. They have roots with a large surface area for rapid absorption of nutrients and water. Their secondary stems can hold stores of water so the plant can withstand periods of drying. ... Orchids also utilize insects to spread their pollen.
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.

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.

Explanation:
During the light dependent reaction,_____ is oxidized to form oxygen. During the light independent reaction, _____
Is reduced to form glucose
Answer:
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.

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.
