If there is an increase in mass, what has happened?

Answers

Answer:

The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Q: Tony has greater mass than the other two boys he is racing (pictured in the opening image).

Explanation:

Answer:

The greater the mass of an object the more it will accelerate! when a given force is applied the mass of the object will change and thats what causes something called speed! Now you will also increase in energy and it will be hard to slow the object down.

True or False: Metals have a higher melting point than water.

Answers

The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.

5. What do porifera use their flagella for?
(1 Point)
O swimming
O eating
reproducing

Answers

Answer:

Porifera use their flagella to eating.

Explanation:

Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.

Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.

The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.

The other options are not correct:

Porifera is immobile, so the flagella do not participate in swimming.Flagella do not participate in the reproductive process of marine sponges.

3. Evaluate Information Sodium is an example of an alkali metal. The alkoli metals are
found in the leftmost column of the periodic table, known as Group 1. Use the interactive
periodic table to explore the properties of the following alkali metals: lithium (Li), sodium
(No), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical
property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?

Answers

Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.

A model of an animal cell is shown above. Eukaryotic cells, like this one, have compartmentalization that allows for efficiency in the cell processes. Identify the names, labels, and roles of three eukaryotic organelles that are involved in the transport, packaging, and export of a protein synthesized on a bound ribosome in this cell.

Answers

Answer:

Three eukaryotic organelles that are involved in the transport, packaging, and export of a protein synthesized on a bound ribosome in this cell are -

Endoplasmic reticulum Golgi bodiesRibosomes

Explanation:

ENDOPLASMIC RETICULUM - The endoplasmic reticulum ( ER) is a broad, dynamic structure that serves many cell functions, including the storage of calcium, protein synthesis and metabolism of lipids. Separate regions, consisting of tubules, sheets and the nuclear envelope, perform the diverse functions of the ER.GOLGI BODIES -: A membrane bound organelle found in most cells is the golgi apparatus. Before secretion, it is responsible for packaging proteins into vesicles and thus plays a key role in the secretory pathway.RIBOSOMES -: The organelles which aid in protein synthesis are ribosomes. For many cell activities, protein is necessary, such as damage repair and other chemical processes.

A ribosome is composed of two subunits:

the small ribosomal subunits- these read the mRNA. The large ribosomal subunits - form amino acid polypeptide chains.

Hence , the labelled diagram of eukaryotic cell is attached below.

what is one reason cell biology is important? explain

Answers

cell bio is important so that we can know more about cells and how they function

Cell biology helps in understanding the state of cell, its functioning, which further helps in understanding the living things more clearly.

Cell biology

• A branch of biology, which examines and studies the function, structure, and behavior of cells.

• All living things are formed of cells, and a cell is the fundamental unit of life, which is accountable for living and working of organisms.

• Cell biology is important as by knowing how the cell functions in both diseased and healthy conditions, the cell biologists can work with plant, animal and medical science and will be able to create novel vaccines, plants with better qualities, and more efficient medicines.

Thus, cell biology is a branch that deals with the study of cells, which can further help in better understanding of the living things around us.

Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.

Answers

Answer:

Explanation:

Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.

In an enzymatic reaction: Select one: a. The enzyme leaves the reaction chemically unchanged b. The least important level of organization for an enzyme is its tertiary structure c. Increasing temperature above the optimal value slows the reaction rate

Answers

Answer:

c. Increasing temperature above the optimal value slows the reaction rate

Explanation:

Enzyme activity is affected by factors, such as temperature, pH, and concentration.

The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.

Thus, the correct option is "C"

c. Increasing temperature above the optimal value slows the reaction rate

Chavez is best known for his use of nonviolent means to draw attention to the poor working conditions of farm workers in the United States. He also formed the National Farm Workers Association in 1962. In 1972, the National Farm Workers Association merged with the Agricultural Workers Organizing Committee to become the United Farm Workers. Chavez led marches, boycotts, and hunger strikes. It is believed that these hunger strikes may have contributed to his death on April 23, 1993. Chavez dedicated his life to improving the lives of farm workers, a life with which he was very familiar. Until he was ten, his parents had owned a farm. They lost this farm during the Great Depression, and he and his family became migrant farm workers. Chavez had to work even harder after his father was injured in an automobile accident. He knew all too well about the poor pay and terrible working conditions withstood by farm workers. Chavez used nonviolent means to fight for the improved treatment, pay, and working conditions of farm workers. He was instrumental in organizing one such famous strike against the California grape growers in 1965, a battle that lasted for years. At one point, Chavez even called for a national boycott against the grape growers. His efforts over the years resulted in several victories for farm workers. After his death, Chavez was awarded the Presidential Medal of Freedom. Which sentence from the passage contains information that could best be used to create a yearbook page about Cesar Chavez? A. Cesar Chavez was born on March 31, 1927, near Yuma, Arizona. B. In 1972, the National Farm Workers Association merged with the Agricultural Workers Organizing Committee to become the United Farm Workers. C.
