Answer:
Chlorophyll A, and B.
Explanation:
Chlorophyll is known as the green pigment which is present in plants. Through the process of photosynthesis, It helps to convert solar light into useful energy. They have light absorption properties, so they are known as photoreceptors. Mainly two types of Chlorophyll are present in plants:
Chlorophyll A: It Is known as the primary photosynthetic pigment and has the ability to absorbs red, blue, and violet lights. Chlorophyll A is the location of the photochemical processes and can absorb light which is needed for the process of photosynthesis.
Chlorophyll B: It mainly helps to absorb blue light which is utilized to fill out the absorption of chlorophyll A it means it helps to supply additional light energy to chlorophyll A. It is known as the accessory pigment.

A new hormone has been isolated from an organism. Although the structure of the hormone has not yet been determined, the hormone is known to exert its effects by forming a hormone-receptor complex that acts as a transcription factor within target cells. What type of hormone is this most likely to be? a peptide hormone a steroid hormone either a steroid or a peptide hormone either a steroid hormone or an amine hormone either an amine or a peptide hormone
Answer:
a steroid hormone-This is genomic pathways.
Explanation
Due to their like -dissolve -like forms steroid hormone are transported free across the phophoslipid membranes. These hormones on reaching the cytoplasm may undergo enzyme mediated alteration, and later binded with specific steroid hormone receptors.
In order to enter the cell nucleus , some of these receptors joined together as a sub unit, called a a dimer.
It is this Dimer which exist as one functional DNA binding unit that enters the cell nucleus. In the latter the steroid-receptor ligand complex binds with a specific DNA sequence to bring about transcription of the targeted gene;to complete genomic pathways.

The given question is not complete. The complete question is:
A company in San Francisco uses petroleum products to make plastics. Arrange the sentences in the correct order to show how the company could be contributing to climate change.
Put in order:
1.Burning fuel releases greenhouse gas
2.higher air temperature causes ocean water to evaporate more rapidly
3.Greenhouse gases trap solar radiation and warm up the atmosphere
4.The company burns fuels to make plastic
5.The amount of water vapor in the air rises, which further increases the air temperature
Answer:
The development of the source of energy that takes place millions of years to form by the action of temperature and pressure under the heap of sediments are known as fossil fuels. The organic matter of dead plants and animals are the raw materials needed for fossil fuel development, however, these are the non-renewable source of energy as it never is replenished once vanished.
These fossil fuels are used in enormous amounts by the industries, which liberate gases like sulfur dioxide, carbon dioxide, nitrous oxide, and other deleterious components upon burning. These gases are the major source of global warming that even contributes to climate change.
Based on the given question, the following are the steps in the correct order that contributes to climate change:
4. The burning of fuel is done by the company to produce plastic.
1. This burning of fuel discharges greenhouse gases in the atmosphere.
3. The trapping of solar radiation takes place by greenhouse gases, which eventually increases the temperature of the atmosphere.
2. This increase in the temperature of the air makes the water bodies like oceans evaporate more briskly.
5. This further results in the increase in the concentration of water vapor in the air that further elevates the temperature of the air.
Where is the blood filtered
Blood is primarily filtered in the kidneys. Kidneys contain nephrons, which filter waste and excess substances from the bloodstream, producing urine as a result. The liver also helps detoxify blood.
Blood is primarily filtered in the human body by the kidneys. The kidneys play a crucial role in maintaining the body's internal environment by filtering blood to remove waste products and excess substances. This filtration process is essential for regulating fluid balance, electrolytes, and blood pressure.
Inside the kidneys, there are numerous tiny filtering units called nephrons, each consisting of a glomerulus and a renal tubule. The glomerulus acts as a sieve, allowing small molecules like water, glucose, and waste products to pass through, while retaining larger molecules like blood cells and proteins. The filtrate, which is the filtered blood minus these waste products, then travels through the renal tubules, where essential substances like water, sodium, and other ions are reabsorbed into the bloodstream, and the remaining waste is concentrated and excreted as urine.
In addition to the kidneys, the liver also plays a role in filtering blood by removing toxins and metabolizing various substances. However, the primary site of blood filtration in the context of waste and excess substance removal is the kidneys.

Evolution is a process of genetic change in a population through variation over successive generations. Evolution involves natural selection and adaptation.
Evolution is a dynamic and ongoing biological process that describes the changes in heritable traits within a population over successive generations. At its core, evolution relies on the concept of genetic variation, which arises through mechanisms such as mutation, recombination, and gene flow. Individuals within a population exhibit diverse traits due to these variations, and the differential survival and reproduction of organisms with advantageous traits lead to the process of natural selection. Natural selection acts as a mechanism that favors the propagation of traits that enhance an organism's fitness in its environment.
Adaptation is a central concept in evolution, representing the gradual adjustment of populations to their changing environment over time. As organisms with traits beneficial to their survival and reproduction are more likely to pass those traits to the next generation, the frequency of advantageous traits increases within the population.

Describe: Imagine a rock on a beach and a rock on the side of a mountain. How
would the factors that control weathering be different for these two rocks?
Answer:
mountainside: temperature extremes have more influencebeach: wind and waves have more influenceExplanation:
It depends on what you mean by "factors that control weathering" and where the beach and mountain are located.
If we assume that the rock on the mountain is at a place that has seasonal snow, and the beach is in a temperate climate, then we can make these observations.
The rock on the mountainside will be "weathered" by freezing and thawing, and by plant growth (roots). These will tend to enlarge any cracks in the rock, breaking it apart. While the mountainside may be windy, that wind may not carry particles that would tend to erode the rock surface.
__
The rock on a beach will be most affected by wave and water action, tending to smooth any exposed surface. Freezing and thawing action is less common, due to the moderating influence of the water on the local weather. In some cases, plant growth may also be a factor. Wind may pick up beach sand, further tending to smooth any exposed surfaces.

a. break the intramolecular bonds
b. expose hidden bacteria in the fatty bolus
c. increase the surface area available for hydrolysis by lipase
d. trigger secretion of pancreatic enzymes
e. pass these molecules through the stomach
Answer:
c. increase the surface area available for hydrolysis by lipase
Explanation:
Emulsification of fats(fatty acid) is a chemical reaction where large molecules(globules) of fats are broken down into a smaller molecules (droplets) by the action of an emulsifier.
In the human body, emulsification takes places in the duodenum during the process of digestion of fats. When large fat molecules have been broken down into smaller fat molecules by action of an emulsifier called bile salts from the gall bladder, a larger surface area is created which makes it possible for the enzyme lipase from the pancreas to react with or act on fat molecules through the process of hydrolysis thereby converting the fats to fatty acids and glycerol for use by the body.
Answer:
Option C
Explanation:
The emulsification of fats is necessary so as to allow to easy break down of large molecules of fats into smaller droplets increasing their surface are such that enzymes like lipases can act on them, digest them breaking them down into fatty acids and glycerol to be easily absorbed by the small intestine.
