How is cytokinesis different
in plants and animals

Answers

Answer:

MAIN DIFFERENCES

- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.

- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.

- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.

What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell

Answers

Answer:

function as the powerhouse of cell

Explanation:

we have read the power house of cell as a mitochondria

Answer: C) Functions as the powerhouse of the cell

==========================================================

Explanation:

The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".

The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.

Atoms are the most basic unit of matter. Two or more atoms from the same or different elements can combine to form molecules.
Cells are the most basic unit of life. Cells are made up of many different types of molecules. Which of the following accurately shows higher levels of organization within organisms, from least complex to most complex?
A. cells → organs → organ systems → tissues → organism
B. cells → tissues → organs → organ systems → organism
C. cells → organ systems → organs → tissues → organism
D. cells → organs → tissues → organ systems → organism

Will pigs ever fly?
Support your answer with suitable examples. ​

Answers

Answer:

NO

Explanation:

the pigs will never be able to fly as the birds have:

wings – these enable the force of lift.

lightweight, smooth feathers – this reduces the forces of weight and drag

streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)

light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight

Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.

Answer:yes they might

Explanation:

Birds are able to breed with pigs and pigs might get wings

Answers

Answer:

C. in the mitochondria

Explanation:

Mitochondrial ADP/ATP carriers transport ADP into the mitochondrial matrix for ATP synthesis, and ATP out to fuel the cell, by cycling between cytoplasmic-open and matrix-open states. ... Because these features are highly conserved, this mechanism is likely to apply to the whole mitochondrial carrier family.

Which of the following is not one of the seven primary odors humans recognize?
fresh
putrid
pungent
roses

Answers

Answer:

roses

Explanation:

It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3

There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.

Answer:

Fresh

Explanation:

When you look at the chartr, Roses were cconsidered a floral scent, which was listed, then there was putrid, pungent, and 3 others, the only one that wasn't listed was fresh, because often out scent and taste work together to help us find rotten foods, but we find that by smelling putrid scents or pungent scents, rather than fresh scents. Therefor the correct response is fresh

which nutrients are present in solution x?

Answers

here is an explanation sorry if it’s long :/


Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. They are used in every process of an organism’s body. Some of the processes are growth (building cells), repair (healing a wound), and maintaining life (breathing).

Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.

From these basic nutrients, plants and other autotrophs synthesize, or create, their own nutrients, such as sugars. The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs. People and animals get most of their nutrients from food.

Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.

Can someone help me if this is correct

Answers

Answer:

I think your answer is wrong. The right answer is D. Nucleus & Ribosome.

Explanation:

A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
