Answer:

Kingdom Protista was first described by Antony van Leeuwenhoek in 1675. The kingdom includes the majority of unicellular and eukaryotic organisms.

Explanation:

Protists are eukaryotic organisms such that they consist of a well-defined nucleus, membrane-bound cell organelles, and are mostly unicellular. However, some of the protists such as algae perform photosynthesis, some protists exhibit mutualism, and some are parasitic.  

Most of the protists are single cells, but they can exist in multicellular forms, in colonies, and can live as single-cell. Some of the examples include giant kelps, euglena, and diatoms.  

Protists such as alga are capable of performing photosynthesis. Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield oxygen and provide energy.  

Protists are one of the diverse kingdoms in the classification of organisms as it comprises moulds, algae, and protozoa. Protists are not classified as plants, fungi, or animals. For example, the division Bryophyte is considered as a primitive division to plants, whereas kingdom Moneran is considered as most primitive.

Explanation:

Answer:

In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.

The statement that Best describes the students' results is option A. Mushrooms grow better at the cooler temperature.

Since the students' are experiment and results are described in the table.

So based on this, we can say that the mushroom should grow better at the cooler temperature.

Also, the number of mushroom should be 34.

Therefore, the option a is correct.

Answer:

1.The period during which a heart chamber is contracting is called systole.

2. The period during which a heart chamber is relaxing is called diastole.

3. During ventricular contraction, the AV valves (tricuspid and mitral valves) are closed.

4. During ventricular relaxation, the AV valves are open.

5. The pulmonary and aortic valves open when the pressure in the ventricles exceeds the pressure in the pulmonary trunk and aorta.

6. The first sound of a cardiac cycle occurs when the atrioventricular valves are closing.

7. The second sound of a cardiac cycle occurs when the semilunar valves are closing.

Explanation:

We can divide the heart cycle into two parts the systole and the diastole. The systole happens when the heart walls contract, and the diastole when these relax.

The relaxation and contraction allow the flow of blood into the different heart chambers.

During diastole, blood flows to the right atrium from the vena cavae superior and inferior, and the coronary veins and to the left atrium from the pulmonary veins. The blood accumulated in the atriums causes the AV valves to open, and blood flows to the ventricles. In this part, the atrium pressure exceeds the ventricular pressure allowing the blood's flow. When the atriums contract, the remaining blood that was in them, goes to the ventricles. Throughout all this process, the pulmonary and aortic valve is closed due to a pressure difference.

During ventricular systole, there are two phases. First, the ventricles contracts themselves, and the ventricular pressure increases, being higher than the atrium pressure. As a consequence, the AV valves close. During this first phase of contraction, there is not enough pressure to open the pulmonary and aortic valves. In the second phase, the ventricles completely contract themselves, the ventricular blood pressure increases. It becomes higher than the pressure in the aortic and pulmonary valves. As a consequence, the blood pushes the valves open, and blood goes out of the heart. Then, the difference in pressure between the ventricles and the pulmonary trunk and aorta causes the valves in these areas to close.

The first sound that we listen to is the S1 and is during the ventricular contraction that closes the atrioventricular valves. The second sound is the S2, and it happens when the semilunar valves close, also knowns as aortic and pulmonary valves. S2 occurs during diastole once that the blood is out of the ventricle and the contraction has finished.

Explanation:

Cactuses can store water nearly four months mainly in the winter and watering is not required for them frequently during that time. The stem acts as a reservoir for the amount of water it holds. The ground tissue of cactus has lots of parenchymal cells that store water.

The ground tissue system comes from a ground meristem which has three tissues, namely parenchyma, collenchyma, and sclerenchyma.

The ground tissue of cactus has many parenchyma cells that store water.

Thus, it can be concluded that the ground tissues helps cactus to store water for a long time.
