GIVE ME GOOD ANSWER PLEASE! WILL MARK AS BRAINLIEST Remove a filament and anther from the flower, and write down your observations. Then, shake the pollen grains from the anther onto a microscope slide, add a drop of water, and place a coverslip on it. Observe the slide under a magnifying glass or a microscope. Describe the differences between the observations made with the naked eye and under magnification. If using a microscope, record specific observations for each magnification used.
Answer: when you put the pollen under a microscope you can see that the pollen isn’t just yellow and looks like dots but that that each one has a different shape and size

protein synthesis is a multistep process. put the steps of protein synthesis in sequential order.
Answer:
Replication - Transcription - Translation
Explanation:
Replication duplicates the DNA so that happens first. Then in transcription converts the DNA to mRNA which goes to the cytoplasm to make proteins. In translation proteins are made when codons and anti codons join to make amino acids which create the proteins.

how do cells get the correct number of chromosomes?
Answer:
"During cell division, a mother cell divides into two daughter cells, and during this process, the DNA in the mother cell, wrapped up in the form of chromosomes, is divided into two equal sets. ... This finding gives us a glimpse of an important step in the process of cell division."
Explanation:
Using the information in Model B as a reference. Which of the following from the elephant is directly available to the lion?
Grass
Respiration
Biomass
Waste
I need this answer quick please!
Answer:
Biomass
Explanation: Grass is not available in its original condition as it's digested.
Respiration doesn't make any sense.
Waste including faecal matter is removed from the organism via urinary and digestive systems.
Biomass is what the lion consumes.
why do trees sometimes get white spots on it
Answer:If you see a suspicious abundance of white spots on your twigs, branches, or leaves, you may have an infestation of scale insects, which are parasites of plants and feed on internal plant fluids. The white spots that you see are in fact thousands of tiny white bugs.

1to 5. Write a 1 by the first event to occur and a 5 by the last event.
5 The number of native clams per sample falls from 100 to 10.
1 Scientists find European Green Crabs in Bodega Bay.
4 Scientists find that the number of native clams per sample has risen to 40.
3 The number of native shore crabs per sample falls from 25 to 20.
2 The number of European Green Crabs per sample falls from 5 to 4.

Explanation:
the pigment-producing cells of the epidermis are located in which layer?
Answer:
Basal Layer
Explanation:
Melanocytes are found in the basal layer of the epidermis. These cells produce a pigment called melanin, which is responsible for different skin color. Melanin is packaged into small parcels (or melanosomes), which are then transferred to keratinocytes.
how does the loss of species affect the entire ecosystem
Answer:
Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Answer:
"When a species becomes extinct, they reduce the variety of animals, plants, or bird species from that ecosystem resulting in the extinction of the other species that were dependent on them. Different species are playing different roles in the ecosystem to maintain a balance of the world." Credits to outside sources that it won't let me say :(

Name a process in plants that uses oxygen. Compare the raw materials and products of this process with those of photosynthesis
Answer:
Cellular respiration uses oxygen. Comparisons below in explanation.
Explanation:
Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).
Photosynthesis has this as its general chemical equation:
[tex]6CO_2 +6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6 + 6O_2[/tex]
Cellular respiration has this as its general chemical equation:
[tex]C_6H_{12} O_6 + 6O_2[/tex] ⇒ [tex]6CO_2 + 6H_2O[/tex]
As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.
