How do flowers attract pollinators
Answer:
Explanation:
Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.
Flowering plants need to get pollenDust-like grains that contain male sex cells (gametes) of flowering plants (angiosperms) and cone plants (gymnosperms). Pollen is made on the anthers of flowering plants. from one flower to another, either within a plant for self-pollination or between plants of the same species for cross-pollination to occur. However, pollen can’t move on its own, so animals or the wind (and water in rare cases) move the pollen for plants.

Photosynthesis is the process by which producers convert energy from the Sun into chemical energy in the form of glucose. Explain why photosynthesis is so important for ecosystems.
Answer:
Some animals feed on plants which make their food through photosynthesis, and most animals feed on animals which feed on plants so, without photosynthesis most living things may go extinct. Right from ma brain
Explanation:
PLZ give a crown
Answer:
plants are called photosynthetic autotrophs...
WHY ARE THEY CALLED PHOTOSYNTHETIC...?!? because they convert light energy (i.e. sunlight) to chemical energy (i.e. glucose) this process is called photosynthesis. The Photosynthetic formula is 6CO2 + 6H2O ---> GLUCOSE + 6O2......
WHY ARE THEY CALLED AUTOTROPHS....?!? because they make their own food by using inorganic sources that is Water and Carbon dioxide. they are fully independant from other organism. So they do not feed on any other organism for survival hence they are found on the bottom of the energy pyramid so if they wouldn't convert light energy into chemical energy all the animals would be dead because we are not autotrophs we can not make our own food by using inorganic sources we need already made organic food thats why those organisms which can not make their own food are called heterotrophs

All of the following is true of GMOs EXCEPT
A. They have increased food production
B. Only animals are modified genetically
C. They can increase resistance to disease
D. Many are concerned that the full impact of GMOs on people is not known
Only animals being modified genetically is not true of GMOs. Genetically
modified organisms(GMOs) usually undergo some changes to their DNA in
order to infuse beneficial trait such as size and taste, resistance to diseases
etc.
The infused trait through DNA alteration helps to increase the quality and
yield of crops thereby making them readily available for the population.
Plants and animals undergo this process and isn't restricted to animals
which makes option B the right choice.

if a cell needs 180 molecules of ATP to perform a function within the cell,home many molecules of glucose and oxygen will be needed. Include in your answer the equation for cellular resperation and how its used to calculate the answer
Answer:
Fill in the word that completes each sentence.
Food contains a sugar called
glucose
which is broken down in a process called cellular
⇒ respiration.
This process uses
⇒ oxygen
Explanation:
The equation for cellular respiration is:
Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)
What is cellular respiration?
Cellular respiration is the process by which cells convert the energy stored in food molecules into a form that can be used by the cell, called adenosine triphosphate (ATP). This process occurs in the mitochondria of eukaryotic cells, and in the cytoplasm of prokaryotic cells.
To calculate how many molecules of glucose and oxygen will be needed to produce 180 molecules of ATP, we can use the ratio of ATP produced per molecule of glucose and oxygen consumed.
The standard ratio of ATP produced per molecule of glucose is 36 ATP per molecule of glucose. Therefore, to produce 180 molecules of ATP, the cell would need to consume 5 molecules of glucose.
The standard ratio of ATP produced per molecule of oxygen is 4 ATP per molecule of oxygen. Therefore, to produce 180 molecules of ATP, the cell would need to consume 45 molecules of oxygen.
So, the cell would need 5 molecules of glucose and 45 molecules of oxygen to produce 180 molecules of ATP through cellular respiration.

Select the correct location on the image. Keiko’s teacher was discussing the theory of endosymbiosis. She asked Keiko to mark the organelles in the diagram that most closely resembled prokaryotes. Which organelles should Keiko mark?.
Mitochondria in animal cells, while mitochondria and chloroplast in plant cells most closely resembled prokaryotes.
What do you mean by endosymbiotic theory?This theory states that organelles such as mitochondria and chloroplast in eukaryotic cells were once prokaryotic microbes.
These organelles when occupied in prokaryotes divide by binary fission. But they become a part of the eukaryotic cell now and result in a symbiosis relationship between each other.
Therefore, Mitochondria in animal cells, while mitochondria and chloroplast in plant cells most closely resembled prokaryotes.

(A) True or (B) False: Two species of lizard with the same thermal niche could coexist in the same range.
The statement "two species of lizard with the same thermal niche could coexist in the same range" is true.
What is species?Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
Two species of lizards are given the same thermal niche. So these lizards have similar characteristics of thermal niches. So these lizards can live in the same range because they can coexist. But in these organisms, there can be competition between them.
The statement can be true as it can coexist in the same range as they have a similar thermal niche. They can live in the same temperature.
Therefore, the statement is false.

Which of the following will best accelerate glycogen storage after physical activity? a. a high-fat meal taken within two hours of exercise completion b. a high-carbohydrate snack within two hours of exercise completion c. a high-protein snack taken midway through exercise and another 30 minutes after exercise
Glycogen storage after physical activity will be accelerated by taking a high carbohydrate snack within two hours of exercise.
What is Glycogen?Glycogen is a polysaccharide that forms glucose after hydrolysis has taken place.
They exists as substance which are deposited in bodily tissues and serve as a store of carbohydrates.
When one consumes a high carbohydrate snack within 2 hours of exercise, muscle tissue which are spongelike will rapidly soak up glucose from the high-glycemic carbohydrates.

Seven times a number minus the number is -48. Find the number
Answer:
the number should be -(8)
Explanation:
7x-(8) = -56 - 8 = -48
The reason I put it in the format that I did is because if you just put -8, that means that you would multiply 7 by -8 and then instead of subtracting -8 from -56 you would be adding it to -56 so your answer would be incorrect. so by putting the negative outside of the parenthesis that means that the number isn't always going to be negative.
This may be wrong but I hope it helps.
Which statement describes an event that occurs during glycolysis that contributes to the production of ATP?
A. Pyruvic acid is broken down to form carbon dioxide.
B. Oxygen molecules are broken down and converted into pyruvic acid.
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
D. Carbon atoms in glucose are transferred to ADP, forming ATP.
Answer:
C. High-energy electrons and hydrogen ions are passed to NAD+ forming NADH.
Explanation:
The sixth step in glycolysis is the first of the two-energy-conserving reactions of glycolysis which results in the formation of ATP. This step involves the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate.
In the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, high-energy electrons and hydrogen ions are passed to NAD⁺ forming NADH.
Glyceraldehyde-3-phosphate + inorganic phosphate + NAD⁺ ----> 1,3-bisphosphoglycerate + NADH + H⁺
The NADH produced in this reaction transports the high-energy electrons passed to it through the electron transport chain to produce ATP in oxidative phosphorylation.
