When they lose their leaves they need much less resources to survive (because they don’t need nutrients to support the leaves). For example trees lose their leaves in the winter because the ground freezes up and it’s harder to suck up nutrients.
What is the difference between a unicellular organism and multicellular organism?
Select one:
a. Unicellular organisms are made up of a single cell, while multicellular organisms are made up of several cells.
b. Unicellular organisms are not living, while multicellular organisms are living.
c. Unicellular organisms are highly organized into tissues and organs, while multicellular organisms are simple.
d. Unicellular organisms do not need water, while multicellular organisms do need water.
Answer:
A.
Explanation:
From the name, "unicellular" you can deduce that "uni" means one, and vice versa for multicellular "multi".
The diagram below shows a type of virus called a bacteriophage. Select the name of the structure that the virus can use inside a host cell to produce new virus particles.
Answer:
It's the DNA..........
The structure that the virus can use inside a host cell to produce new virus particles is the DNA.
Bacteriophage which literally means bacteria eater is a type of virus that has the ability to infect bacteria.
Basically all bacteriophages consist of nucleic acid molecule (DNA) which is surrounded by a protein coat( the capsid head).
It also possess a tail sheath through which it transfers it's DNA into host cell.
Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis.
Therefore, the structure that the virus can use inside a host cell to produce new virus particles is the DNA.

How does Klinefelter syndrome caused by nondisjunction might have occurred??
Answer:
Cause. Klinefelter syndrome usually occurs as a random event during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes.

Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

What phase of mitosis is shown in the picture above?
A. Metaphase
B. Anaphase
C. Telephase
D. Prophase
The phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.
What is Mitosis?Mitosis may be defined as the type of cell division in which two daughter cells are formed from a parental cell with the exact number of chromosomes.
In metaphase, the chromosome usually lines up in one plane and forms an equatorial plate in which they are attached to the spindle fiber through their centromere.
Therefore, the phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.

Which pair is correct?
a. G2 phase, preparation for mitosis
b. G1 phase, DNA replication
c. M phase, cell growth
d. S phase, cell division
A pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next.
In the G1 phase of the cell cycle, the cell grows in size and synthesizes mRNA as well as proteins which are required for DNA synthesis.
M-phase governs the nuclear division (Karyokinesis), and cytoplasm division ( cytokinesis).
S-phase is known to double the amount of genetic content within the cell.
Therefore, a pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.

Which statement is not an example of how the use of resources has changed?
A. More products are made from recycled materials.
B. Cars still largely rely on oil.
C. Car companies have developed hybrid cars.
D. More wind farms are present in the United States.
Answer:
B. Cars still largely rely on oil.
Explanation:
Nowadays, most countries still use transportation systems that burn fossil fuels. An example of this may be private cars that consume gasoline, which derives from fossil fuels (oil). The use of fossil fuel transportation systems increases the emission of carbon dioxide (CO2), a major greenhouse gas involved in global warming. In the near future, it is expected that fossil fuel-based vehicles can be replaced by electric cars that use energy obtained from renewable sources (e.g., solar energy, wind energy, etc).

What would happen if the rate of evaporation reduces
Answer:
When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.
Answer:
if the rate of evaporation reduces water cylcle will stops and amount of water present in the world will be increase.humifity will be more.

Explanation:
A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, which is an animal that eats a plant or another animal.
Green plants are producers
They are the first link in all food chains
Plant cells contain chlorophyll and can photosynthesise
Photosynthesis produces glucose and oxygen
Animals are consumers
If they eat plants, they are the first-order consumers or herbivores
The chemical energy in the green plants is transferred to the animal when it eats the plant .
