Answer:
cell; prophase. prometaphasemetaphase. anaphase, telophase.Explanation:
Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.

e. the spinning of a celestial body, such as a planet, around
an axis
Answer:
Axis - B
Rotation - E
Revolution - D
Latitude - A
Gravity - C
Explanation:
The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.
The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.
Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year
Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.
Gravity is the force that keeps things together. Large masses have gravity that attract other masses.

true or false: cardiac contractile cells have thick and thin filaments arrangement in sarcomeres.
Answer:
True
Explanation:
This is because sacromere is the basic unit of cardiac muscles which is made up of thin and thick filaments. Cardiac muscle is consist of the contractile cells of the heart which it's appearance is striated as a result of alternating thick and thin filaments which is composed of myosin and actin. Actin and myosin are both firm contractile protein filaments, the actin form the thin filaments, and myosin form thick filaments.
Which of the following is phosphorus not used for?
A. Cell membrane
B. Lipids
C. ATP
D. Nucleotides
The phosphorous is not necessary for lipids. The correct option is B.
What are lipids?A lipid is any organic molecule that is not soluble in water. They encompass fats, waxes, animal fats, hormones, and certain membrane constituents that serve as energy storage molecules and chemical messengers.
Even though the term "lipid" is occasionally used interchangeably with "fats," fats are a subcategory of lipids known as triglycerides.
Lipids also include fatty acids and their variants, in addition to other sterol-containing metabolites like cholesterol.
Adenosine 5′-triphosphate abridged ATP and generally represented without the 5′-, is a vital "energy molecule" found in all phosphorous-containing life forms.
The presence of phosphorous is also required by the cell membrane and nucleotides.
Thus, the correct option is B.

what makes lipids/fats hydrophobic?
Answer:
Lipids are hydrophobic because they do not mix with water. Lipids are made of long chains of carbon and hydrogen. ... The partial charges on the water molecule cannot interact with the neutral lipid molecule and thus water and lipids do not mix.
Answer:
"this hydrophobic ("water fearing") nature of lipids is driven by the bonds between these many carbons and hydrogens. ... Thus, long chains of carbon-hydrogens bonds form a nonpolar molecule."

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

A scientist exploring in the rainforest found an unclassified organism. It is multicellular and made of multiple thread-like structures. The organism has cells with a nucleus and a cell wall made of chitin. The scientist should classify this organism as belonging to the kingdom—
Answer:
Kingdom Fungi
Explanation:
Based on certain characteristics possessed by living organisms, they have been classified into five different kingdoms namely; plantae, animalia, monera, protista and fungi. Organisms with similar characteristics have been placed under the same kingdom.
Kingdom Fungi is a kingdom that contains organisms that possess characteristics different from plants and animals. Some of these features are those possessed by the unclassified organism found in the rainforest and they are as follows:
- They are eukaryotic (possess a true nucleus) and multicellular (have more than one cell).
- Their cell wall is made of chitin (a carbohydrate)
- They are made of multiple thread-like structures called HYPHAE.
Based on these mentioned characteristics above, the scientist should classify this organism as belonging to the kingdom FUNGI.

O All are tall and purple
O Three-quarters of the plants are short and white
All are short and white
Three-quarters of the plants are tall and purple
Answer:
A. All are tall and purple
Explanation:
When you set up a punnet square, all of the results would be TtPp.
When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).
So to break it down:
Tt -> tall plant
Pp -> purple plant
so they are all tall and purple.
For your given bite of food, outline or use a flow chart to show what happens to this piece as it moves down the digestive tract. Take notes in your laboratory journal about how this bite is processed in the digestive tract. Mention key enzymes, describe mechanical and chemical digestion, and discuss absorption of nutrients and removal of wastes.
Answer: Mouth (amylase digest carbohydrates), esophagus, stomach (digestion of proteins by pepsine), small intestine (digestion of fats, proteins and carbohydrate by pancreatic enzymes and bile), large intestine (it receives the indigestible substances, absorbs the water and leaves the waste products called feces, peristalsis helps move stool into the rectum and feces are expelled from the body through the rectum and anus). Insulin facilitates glucose uptake by the cells and glucagon turns glycogen into glucose.
Explanation:
The gastrointestinal tract is a series of hollow organs joined together in a tube from the mouth to the anus. The organs found there are the mouth, esophagus, stomach, small intestine, large intestine and anus. The liver, pancreas and gallbladder are the solid organs of the digestive tract that also have important functions during digestion.
Digestion is important because the organism needs nutrients to function properly. (carbohydrates, proteins, fats, vitamins). So, the digestive system breaks down nutrients into small parts so that the body can transport and absorb them. During digestion, carbohydrates are broken down into simple sugars, proteins into amino acids and fats into fatty acids and glycerol.
The digestion of food begins in the mouth, where the food is chewed. The saliva possesses enzymes that already begin with the degradation of starches and sugars. The two most important proteins in saliva are amylase (produced by parotid glands) and mucin (produced by sublingual and submandibular glands). When the person swallows, the tongue pushes the food down the throat and the epiglottis folds over the windpipe to prevent choking and so the food passes into the esophagus. The food bolus then passes through the esophagus, where a process called peristalsis takes place to transport the food.
Then the food reaches the stomach, where the upper muscle in the stomach relaxes (esophageal sphincter) to allow the food to enter and the lower muscle of the stomach mixes the food with the digestive juice. This sphincter remains closed to prevent the content in the stomach from flowing back into the esophagus. Protein digestion begins in the stomach with the action of pepsin and continues in the small intestine with pancreatic enzymes such as trypsin (produced in the pancreas), chemotrypsin, aminopeptidases and carboxypeptidases. So, the stomach acid and enzymes act there, which are molecules created by our body that are responsible for breaking down the polymers present in food into smaller molecules so that they can be easily absorbed.
The food then passes into the small intestine and is transported along the small intestine by peristaltic movements. There, fats, proteins and carbohydrates are digested. The small intestine has three parts: duodenum, jejunum and ileum. The pancreas produces pancreatic juice and the liver produces bile, and these two juices are discharged into the small intestine. Bile helps to dissolve fats, which facilitates their assimilation. Meanwhile, the pancreatic juice completes the digestion of proteins and sugars, a process that began in the stomach, together with the intestinal juice produced by the walls of the small intestine. Once the food has been digested, its components must pass into the blood to be distributed to all the organs of the body. The inner walls of the small intestine has intestinal villi which are irrigated internally by blood vessels and they are responsible for the absorption of water and nutrients into the bloodstream. So, when the digestive enzymes have dissociated the large molecules into small components, the products are absorbed by the wall of the intestine. The mucosa of the small intestine also secretes the hormone secretin, which stimulates the pancreas to produce digestive enzymes.
Finally, the large intestine is involved, where bacteria (microbiota) in the large intestine can also chemically break down food. The large intestine includes the appendix, cecum, colon and rectum and it receives the indigestible substances from the small intestine, absorbs the water and leaves the waste products called feces. The colon, is the last structure to process food. Peristalsis helps move stool into the rectum and feces are expelled from the body through the rectum and anus.
After digestion, glucose will be available as a source of energy. Once it begins to circulate in the bloodstream, it will need the help of a hormone called insulin to enter the cells and provide them with the energy they need. Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and it helps cellular glucose uptake by signaling cells to take in glucose from the blood. If the body has enough energy. On the other hand, glucagon turns a type of stored sugar called glycogen into glucose, which goes from the liver into your blood to provide energy.
