Answer:

the nucleolus

Explanation:

In the eukaryotic cell, the subunits that make up ribosomes are synthesized in the nucleolus. Once formed, these subunits pass through nuclear pores and are functional only in the cytoplasm when the two subunits are attached to an RNA molecule. Ribosomes are machines for translation.

Answer:

Cilia and flagella are slender, hair-like structures that protrude from many types of cells. In many cells, cilia act as a fundamental unit of motion, serving as key organelles that convert chemical energy into mechanical work in the form of an oscillatory beating motion.Flagella acts primarily as an organelle of locomotion in the cells of many living organisms.In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.Cilia are present on the surface of the cell in much greater numbers. Ciliated cells often have hundreds of cilia but flagellated cells usually have a single flagellum. The function of cilia is to move water relative to the cell in a regular movement of the cilia.

Explanation:

Answer:

During transpiration, water will evaporate from tiny holes in the surfaces of leaves into the air (the tiny holes are called stomata). As the water molecules evaporate from plant leaves, they attract the water molecules still in the plant, helping to pull water up through the stems from the roots.

Answer:

In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.

Explanation:

Answer:

see explanation

Explanation:

Meiosis is involved in gamete reproduction and results in four genetically distinct daughter cells. In contrast, mitosis involves the somatic cell and results in two genetically identical daughter cells. In mitosis when the division is complete you have two diploid cells. A diploid cell has two sets of chromosomes. Whereas with meiosis whose goal is to produce gametes you end up with 4 haploid cells. A haploid cell has just a single set of chromosomes. Meiosis and mitosis go through very similar phases however meiosis crossing over takes place and variation occur. Mitosis the division takes place in four stages and in Meiosis there is a two-division process of four stages each.

Explanation:

In frameshift mutations, the addition or deletion of 1,2 or 4 nucleotides occurs, which changes the ribosome reading frame. In single-nucleotide substitution, only one is substituted, as the name implies. A single substation is when one of our DNA bases is replaced with another and changes one amino acid. In Frame-shift, mutations usually have more significant effects on the final proteins. Frame shifts can affect the entire chain of proteins.

Answer:

The difference threshold

Answer:

Explanation:

Answer: The recycling of. NAD+ allows glycolysis to continue. The products of this process are two molecules of an alcohol, often ethyl alcohol, two molecules of carbon dioxide, and two molecules of NAD+. Just like lactic acid fermentation, alcoholic fermentation recycles NAD+ and so allows glycolysis to keep making ATP.

I hope this helps! Good luck!

Answer:

Image result for What is an enzyme?

An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process.

Answer:

D

Explanation:

ATP formatioon is not a photosyntheic process, neither is NADPH formation. The calvin cycle is correct because it can happen with or without light

Answer: Protein is healthy

Explanation: Protein is in milk, juice

Answer:

Where I am it's called the Independent variable (Manipulated), but anyway, the manipulated variable is whether the plant has fertilizer or not, and the responding variable is the height growth of the plants.

Explanation:

Answer:

an individual animal, plant, or single-celled life form.

Explanation:

yes! thats there the same exact thing your just explaining the definition of mitochondria

Explanation:

Answer:

I dont know there are no options

Explanation:

Answer:

Those that are biodegradable.

Answer:

cytosine is one of the three pyrimidine nucleobases used in forming nucleotides of the nucleic acid

It is located opposite guanine in the DNA double helix

It pairs with guanine in both DNA and RNA forming three hydrogen bonds

cytosine is one of the nitrogenous bases coding the genetic information molecules carry

It can even be modified into different bases to carry epigenetic information

Answer:

an electron is excited. As electrons are passed through the system of electron carriers associated with photosystem II, they lose energy

Answer:

Answer:

3. The equator receives more direct sunlight than the North Pole.

Explanation:

Answer:

A) The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.

B) The five major hormones are: gastrin ( stomach ),                                                          secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).

Explanation:

Explanation of answer A):

Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Answer:

mitosis and cytokinesis.

Explanation:

Microwave sources include artificial devices such as circuits, transmission towers, radar, masers, and microwave ovens, as well as natural sources such as the Sun and the Cosmic Microwave Background. Microwaves can also be produced by atoms and molecules. <3
