PLZ HURRY
Answer:
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.
Explanation:
Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

Explanation:
Giraffes are herbivores that initially had shorter necks. They are found in grasslands and areas where trees grow tall. To feed on leaves from tall trees, giraffes had to stretch their necks. This behavior paved the way for
of giraffes with longer necks. A giraffe’s long neck is a
adaptation.
This behavior paved the way for natural selection of giraffes with longer necks. A giraffe’s long neck is a structural adaptation.

Leukemia is a malignant progressive disease in which the bone marrow and other blood-
forming organs produce increased numbers of immature or abnormal white blood cells.
Which statement about cell cycle checkpoints describes how this disease occurs?
A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.
Answer:
A Dysfunctional checkpoints may lead to abnormal cell growth.
Explanation:
One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.
There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

The correct answer is c, plz give me brainlest
Explanation:
got 100 percent on the quiz
A property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.
What is Radioactive dating?Radioactive dating may be defined as a type of methodology for dating rocks and minerals with the help of radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.
Potassium-argon dating is a method of determining the time of origin of rocks by estimating the ratio of radioactive argon in order to radioactive potassium in the rock. This dating method is typically based on the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks.
Therefore, a property of argon that makes it useful for potassium-argon dating is that it decays into potassium. Thus, the correct option for this question is A.

A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
Answer:
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic
Explanation:
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
-this is a plant cell because of the cell wall
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
-prokaryotes don't have DNA contained in a nuclear membrane
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
- DNA contained in a nuclear membrane --> eukaryototic
- cell wall --> plant cells, which are eukaryotic
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

Write the overall equation for photosynthesis using words?
Answer:
carbon dioxide + water =glucose +oxygen
Explanation:
hope this helps :)
The overall equation for photosynthesis using words is:
Carbon dioxide + water + sunlight energy → glucose + oxygen
Photosynthesis in plant chloroplasts and photosynthetic microorganisms is a complex metabolic process. Photosynthesis equation: [tex]CO_2 + H_2O + sunlight = glucose (C_6H_{12}O_6) + O_2.[/tex]
Photosynthesis converts carbon dioxide and water into glucose and oxygen. Special pigments like chlorophyll collect sunlight and transform it into chemical energy.
Photosynthesis underpins the food chain and sustains life on Earth. Primary producers, plants synthesise glucose that sustains all other organisms' growth and development. Photosynthesis provides oxygen for respiration and regulates carbon dioxide levels, preserving Earth's atmosphere.
