The right option is d) bubbles

The production of bubbles when baking soda mixes with an acid such as vinegar is the observation that indicated a chemical property of the baking soda.

Baking soda (also known as sodium bicarbonate) is a nonflammable, white crystalline powder. Baking soda is odorless, and alkaline. Baking soda reacts with vinegar (acetic acid) to produce carbon dioxide (a gas), water, sodium ion and acetate ion. Baking soda is used for many purposes such as; as an antacid for treating indigestion, for baking, in fire extinguishers, as a water softener, as a pesticide, and to remove dirts from materials.

A spectacular marine animal has a network of glassy spicules that forms a sac-like structure. This animal does not have true tis
PolarNik [594]

Answer:

Sponges use <em><u>choanocytes</u></em> or <em><u>flagellated channels</u></em> to get nutrients from the feeding cells to other parts of their body.

Explanation:

Sponges are marine animals with a sac-shaped body. The epidermis is composed of polygonal flat cells called pinacocytes and pores protected by porocytes. Under the epidermis, there is a protein matrix called mesenchyme, which is composed of spicules and <em><u>amibocytes</u></em>. By the interior side of the sponge, there are the<em><u> choanocytes</u></em>. These are ovoid cells that can be shaping the spongocoele (internal cavity of the sponge), with an extreme attached to the mesenchyme and the other extreme projected to the spongocoele, or can be grouped in spaces called <em><u>flagellated channels</u></em>.

These animals depend on water to get oxygen and food to the inside of the sac and take excrements and reproductive cells to the outside. Sponges <em>feed on small detritus particles and suspending organisms</em> that get near the animal by water streams produced by choanocytes.

Particle size is essential. Only the small ones can get through the flagellated channels, where they get stuck to the choanocytes and are encapsulated by the cells. If the choanocytes are too small, the particle is transferred to the amibocytes for digestion. These last ones also act as food storages. Excrement products are dragged by a water stream.

How many covalent bonds can carbon make?
Ostrovityanka [42]

Answer:

4

Explanation:

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

Jason has five equally massed lead fishing weights, each weighing 250 grams. What is the total mass of the five lead fishing wei
algol [13]

Answer:

1250 g=1.25 Kg

Explanation:

We are given that Jason has five fishes of equally massed lead fish weights.

Weigh of each fish =250 grams

We have to find the value of total mass of the five lead fishing weights

Total number of fishes=5

In order to find the total mass we will use unitary method

Total mass is obtained by multiplying the total number of fishes with weight of one fish

Total mass=5\times 250

Total mass of five fishes=1250 g

1 kg =1000g

Then 1250 g=\frac{1250}{1000}=1.25 Kg

Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
