Which answer choice correctly identifies structures A, B, C, and D?A.Chromosome; centromere; homologues; sister chromatidsB.Sister chromatids; centromere; homologues; chromosomeC.Homologues; centromere; homologous chromosomes; spindle fibersD.Chromosome; centromere; sister chromatids; homologous chromosomes
Answer:
The structure of the materials are given below.
Explanation:
If the structure of the picture is thread-like we called it chromosomes. If the structure in a chromosome that holds together the two chromatids is known as centromere. Half part of the duplicated chromosome is known as Sister chromatid. If two material has same size and shape we called it homologous structure such as sister chromatids.

thylakoid? choose all that apply
1.breakdown of glucose
2.pumping of hydrogen across that thylakoid
membrane

4.splitting of CO2
Answer: splitting of water + pumping of hydrogen across that thylakoid membrane.
Explanation:
The sources of Hydrogen in the thylakoid are- Pumping of hydrogen across the thylakoid membrane; Splitting of water molecule. Thus, the correct options are 2 and 3.
What is Photosynthesis?Photosynthesis is the process through which plants make their food. This process takes place in the chloroplast of plant cell. The chloroplast contains Photosystems- PSI and PSII which are responsible for photosynthesis. The hydrogen ions required by the plants are obtained by the Photolysis (splitting of water molecules) to release oxygen and hydrogen. This occurs in photosynthesis. i.e., photosystem-II.
To replace an electron in the reaction center in PSII, a molecule of water is split. This releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space.
The hydrogen ions are pumped actively through ATP synthase. This uses up ATP energy and causes the production of ADP and phosphate. The Ubiquitin protein present in the membrane is the carrier for hydrogen ions.
Therefore, the correct options are 2 and 3.

Which corrections should be made to describe photosynthesis accurately?
Answer:
try this
Explanation: (1) Light energy and chemical energy should be switched. (2) Chemical energy should be changed to mechanical energy
Explanation:
Answer:Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Which of the following would provide the most energy in an ecosystem?
A. Omnivore
B. Carnivore
C. Producers
D. Herbivores
Answer:
The one that would provide the most energy in an ecosystem are producers!
Explanation: On the food chain and in the ecosystem they contain the most energy. About 90% is lost through heat and and movement of the animals. Lets say you have 10,000 kelo calories, then you have the producer and then your 3 animals, this means the last one only gets 10 kelo calories!
The following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.
What is the significance of the producers in energy production?Producers include plants, algae, and some bacteria that serve as the primary source of energy, converting light or chemical energy into a form of food such as glucose, and in every ecosystem, the producers have many important roles. Herbivores and carnivores all depend on them, both directly and indirectly.
Hence, the following would provide the most energy in an ecosystem: producers, which are in Option c, as the producers are organisms such as algae and green plants that can synthesize their own food using the energy of the sun.

it's a comet i hope it helps
Its structure is considered to be like a large dirty snowball is Comet. Thus, option A is correct.
What is commet?Objects that are generally smaller than planet as the Asteroids, meteors, and stars have one thing in common which is they all smaller object that a planet which in turn means that the planet is bigger that them.
Asteroids are smaller in nature than planet and meteors are smaller in nature than planet and the Stars are smaller in nature than planet. Asteroids- are made from minerals and rock. Meteors- is made from space debris and rocks Comets- are made from Frozen gasses,ice, and rocks.
Asteroids, comets and meteors are small objects present in the galaxy which orbits the planets such as earth. They are very small when compared to the planets.
Some stars are bigger than certain planets therefore the group of objects comprising of stars do not explicitly represent the group of objects smaller than planets.
Therefore, Its structure is considered to be like a large dirty snowball is Comet. Thus, option A is correct.

Answer:
Exocytosis is the reverse of endocytosis. Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.

Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Answer:
Light energy.
Explanation:
Light energy cannot reach the chloroplasts, preventing ATP, NADPH and sugars because light energy is responsible for photosynthesis in algae. if light energy is not available to algae, then no photosynthesis happens and as a result no energy produced in the form of ATP, NADPH and sugars in the body of algae. so we can conclude that light energy is responsible for the preventing of production of ATP, NADPH and sugars.
GBR or Great Barrier Reef is the largest coral reef, which includes many marine organisms and corals. The GBR water is inhibiting the growth of algae mostly due to Diuron.
Diuron is an unmanageable pesticide found in the GBR. Diuron is highly toxic, persistent, and can travel long paths. Diuron interferes with photosystem II by blocking the electron transfer. PSII is an important membrane protein complex, which plays a crucial role in oxygenic photosynthesis. Thus, any interference in PSII will interfere with the production of NADPH and ATP.
However, the high temperature and paraquat can affect algae in the following ways:
Paraquat is also a herbicide, which has toxic effects on the organisms. Exposure to Paraquat has shown significant damage to the cell and inhibited cell growth. High Temperature is one of the major concerns worldwide. Due to global warming, all the organisms, terrestrial or marine are in danger.To know more about GBR, refer to the following link:
